PERFORMANCE VESTING 

LTIP UNIT AGREEMENT 

(2020 Stock Award and Incentive Plan)  

This PERFORMANCE VESTING LTIP UNIT AGREEMENT, dated as
of                 (the “Agreement”), by and between Apartment Income REIT Corp., a Maryland corporation (the “Company”),
and                (the “Recipient”). Capitalized terms used but not otherwise defined in this Agreement shall have the respective meanings set forth in
the Apartment Income REIT Corp. 2020 Stock Award and Incentive Plan, as amended (the “Plan”). 
 WHEREAS,
effective                 (the “Date of Grant”), pursuant to the Plan and the Partnership Agreement the Compensation and Human Resources
Committee (the “Committee”) of the Board of Directors (the “Board”) of the Company granted the Recipient this LTIP Unit Award and hereby causes the Partnership to issue to the Recipient the maximum number of LTIP
Units set forth below, having the rights, restrictions, limitations as to distributions, qualifications and terms and conditions of redemption and conversion set forth herein, in the Plan and in the Partnership Agreement. 

NOW, THEREFORE, in consideration of the Recipient’s services to the Company and for other good and valuable consideration, the receipt
and sufficiency of which are hereby acknowledged, the parties hereto agree as follows: 
  

	1.	 Number of LTIP Units. The Company hereby grants the Recipient an LTIP Unit Award (the “LTIP
Award”) with a target of                LTIP Units (the “Restricted LTIP Units”) pursuant to the terms of this Agreement, the provisions of the
Plan and the provisions of the Partnership Agreement. The target number of LTIP Units subject to this LTIP Award (the “Target Award”) was determined by dividing
$                 by $                , which was the average closing price
of Company’s Common Stock on the New York Stock Exchange for the five trading days up to and including the Date of Grant. The Recipient may ultimately vest into more LTIP Units or fewer or no LTIP Units, as set forth in more detail in this
Agreement. The Recipient shall be admitted as a partner of the Partnership with beneficial ownership of the Restricted LTIP Units as of the Grant Date by (i) signing and delivering to the Partnership a copy of this Agreement and
(ii) signing, as a limited partner, and delivering to the Partnership a counterpart signature page to the Partnership Agreement (attached hereto as Exhibit A).  

 

	2.	 Restrictions and Restricted Period. 

 

	 	(a)	 Restrictions. LTIP Units granted hereunder may not be sold, assigned, transferred, pledged, hypothecated
or otherwise disposed of and shall be subject to a risk of forfeiture until the lapse of the Restricted Period (as defined below). Neither the Company nor the Partnership shall be required (i) to transfer on its books any LTIP Units which shall
have been sold or transferred in violation of any of the provisions set forth in this Agreement, or (ii) to treat as owner of such LTIP Units or to accord the right to vote as such owner or to pay dividends to any transferee to whom such LTIP
Units shall have been so transferred. 

	 	(b)	 Lapse of Restrictions; Restricted Period. The restrictions set forth above shall lapse and the
Restricted LTIP Units shall become freely transferable (provided, that such transfer is otherwise in accordance with federal and state securities laws) and non-forfeitable as set forth in
this Section 2(b) and on Exhibit B. 

  

	 	(i)	 The Company’s total shareholder return (as defined in more detail on Exhibit B, “TSR”)
over the period beginning on                 and ending on                
(the “Performance Period”), as calculated by comparison to the indices stipulated on Exhibit B to this Agreement (and using the methodology set forth on such Exhibit B), shall be compared to the threshold, target and maximum TSR
hurdles set forth on Exhibit B to determine the “Vesting Portion” (as defined on Exhibit B) of the LTIP Award as a percentage of the Target Award. Such calculations shall be determined by the Committee no later
than                (the date of such determination, the “Determination Date”). Restrictions with respect
to                % of the related Vesting Portion of the LTIP Award set forth on Exhibit B shall lapse as of the later of the Determination Date and
the                 anniversary of the Date of Grant (the “Vesting Date”), with the restrictions on the
remaining                % of such Vesting Portion lapsing on the                
anniversary of the Date of Grant (the “Anniversary Date”). 

  

	 	(ii)	 Except as set forth in Section 3, each such lapse of restrictions shall occur only if the Recipient has
remained employed by the Company through the Vesting Date or the Anniversary Date, as the case may be (the “Restricted Period”). The portion of the Restricted LTIP Units which does not vest as of the Vesting Date (or the Anniversary
Date, as the case may be) based on TSR performance shall be forfeited to the Company without payment of any consideration by the Company, and neither the Recipient nor any of his or her successors, heirs, assigns or personal representatives shall
thereafter have any further rights or interests in such shares of Restricted LTIP Units. 

  

	 	(iii)	 All determinations with respect to the calculations pursuant to this Agreement shall be made in the sole
discretion of the Committee. 

  

	 	(c)	 Distributions. 

 

	 	(i)	 For purposes of this Agreement, the “Distribution Participation Date” with respect to LTIP Units
granted hereunder that have vested in accordance with Section 2(b) hereof shall be the Vesting Date or Anniversary Date, as the case may be. Such vested LTIP Units shall be entitled to receive the full distribution payable on Partnership Common
Units outstanding as of the record date next following the date set forth in the preceding sentence, whether or not they will have been outstanding for the whole period. 

 

	 	(ii)	 From and after the Date of Grant and prior to the applicable Distribution Participation Date, the Recipient
shall be entitled to receive distributions with respect to such Restricted LTIP Units in accordance with the terms of 

  
 2 

	 	
the Partnership Agreement; provided, that the Recipient’s Sharing Percentage for purposes of the Partnership Agreement shall be         % (the
“Current Distributions”). 

  

	 	(iii)	 An amount equal to (i) the difference between (x) all distributions paid with respect to one
Partnership Common Unit between the date of grant of an LTIP Unit granted hereunder and the applicable Distribution Participation Date of such LTIP Unit and (y) the Current Distributions paid with respect to such LTIP Unit up to the
Distribution Participation Date of such LTIP Unit (such difference, the “Contingent Distributions”) multiplied by (ii) the number of LTIP Units granted hereunder with the same LTIP Unit Distribution Participation Date
shall be credited to a notional (unfunded) account for the benefit of the Recipient on the books and records of the Partnership subject to vesting. As promptly as practicable after the applicable Distribution Participation Date, an amount equal to
the Contingent Distributions that would have been paid with respect to such LTIP Units that have become vested pursuant to Section 2(b) hereof shall be paid to the Recipient. Any portion of the notional account that is not payable to the
Recipient shall be forfeited and revert to the Partnership free and clear of any claims by the Recipient. 

  

	 	(iv)	 To the extent that the Partnership makes distributions to holders of Partnership Common Units partially in cash
and partially in additional Partnership Common Units or other securities, unless the Administrator in its sole discretion determines to allow the Recipient to make a different election, the Recipient shall be deemed to have elected with respect to
all LTIP Units eligible to receive such distribution to receive         % of such distribution in cash and         % in Partnership Common Units or other securities,
with the cash component constituting the Current Distribution prior to the Distribution Participation Date. 

  

	3.	 Termination of Employment. Except as otherwise set forth in this Agreement, in the event that the
Recipient ceases to be employed by the Company for any reason prior to the lapse of the Restricted Period, then the Restricted LTIP Units shall be forfeited to the Company without payment of any consideration by the Company, and neither the
Recipient nor any of his or her successors, heirs, assigns or personal representatives shall thereafter have any further rights or interests in such Restricted LTIP Units. In the event that the Recipient’s employment with the Company is
terminated due to his death or total and permanent disability, then the Restricted Period set forth in Section 2(b) hereof shall immediately lapse and the Restricted LTIP Units shall become immediately and fully vested, with the level of TSR
performance calculated as if the date of termination was the final day of the Performance Period, and as if the level of TSR performance as of such date was the higher of (a) target or (b) actual TSR performance as of such date, as
determined in the sole discretion of the Committee in accordance with Section 2(b) and Exhibit B. Restricted LTIP Units not vesting in accordance with the foregoing sentence shall be forfeited to the Company without payment of any consideration
by the Company, and neither the Recipient nor any of his or her successors, heirs, assigns or personal representatives shall thereafter 

  
 3 

	 	
have any further rights or interests in such Restricted LTIP Units. For purposes of this Section 3, the Recipient’s employment will have terminated by reason of total and permanent
disability if, in the reasonable and good faith judgment of the Committee, the Recipient is totally and permanently disabled and is unable to return to or perform his or her duties on a full-time basis. 

 

	4.	 Change in Control. The Restricted LTIP Units issued hereunder shall, in addition to any provisions
relating to vesting contained in this Agreement, become immediately and fully vested, and the Restricted Period set forth in Section 2(b) hereof shall immediately lapse, upon the termination of the Recipient’s employment with the Company
by the Company without Cause or by the Recipient for Good Reason, in either case within twelve (12) months following the occurrence of a Change in Control (as defined below), with the level of TSR performance calculated as if the date of the
Change in Control was the final day of the Performance Period, and as if the level of TSR performance as of such date was the higher of (a) target or (b) actual TSR performance as of such date, as determined in the sole discretion of the
Committee in accordance with Section 2(b) and Exhibit B. 

  

	 	(a)	 For purposes of this Agreement, a “Change in Control” shall mean the occurrence of any of the
following events: 

  

	 	(i)	 an acquisition (other than directly from the Company) of any voting securities of the Company (the
“Voting Securities”) by any “person” (as the term “person” is used for purposes of Section 13(d) or Section 14(d) of the Securities Exchange Act of 1934, as amended (the “Exchange
Act”)) immediately after which such person has “beneficial ownership” (within the meaning of Rule 13d-3 promulgated under the Exchange Act) (“Beneficial Ownership”) of 50% or more of the combined voting power of
the Company’s then outstanding Voting Securities; provided, however, in determining whether a Change in Control has occurred, the acquisition of Voting Securities in a Non-Control Acquisition (as
hereinafter defined) shall not constitute an acquisition that would cause a Change in Control. “Non-Control Acquisition” shall mean an acquisition (A) by or under an employee benefit plan (or a
trust forming a part thereof) maintained by (1) the Company or (2) any corporation, partnership or other person of which a majority of its voting power or its equity securities or equity interest is owned directly or indirectly by the
Company or in which the Company serves as a general partner or manager (a “Subsidiary”), (B) by the Company or any Subsidiary, or (C) by any person in connection with a Non-Control
Transaction (as hereinafter defined). “Non-Control Transaction” shall mean a merger, consolidation, share exchange or reorganization involving the Company, in which (1) the stockholders
of the Company, immediately before such merger, consolidation, share exchange or reorganization, own, directly or indirectly immediately following such merger, consolidation, share exchange or reorganization, at least 50% of the combined voting
power of the outstanding voting securities of the corporation that is the successor in such merger, consolidation, share exchange or reorganization (the “Surviving Company”) in substantially the

  
 4 

	 	
same proportion as their ownership of the Voting Securities immediately before such merger, consolidation, share exchange or reorganization, and (2) the individuals who were members of the
Board of Directors of the Company immediately prior to the execution of the agreement providing for such merger, consolidation, share exchange or reorganization constitute at least 50% of the members of the board of directors of the Surviving
Company; 

  

	 	(ii)	 the individuals who constitute the Board as of the date hereof (the “Incumbent Board”) cease
for any reason to constitute at least 50% of the Board; provided, however, that if the election, or nomination for election by the Company’s stockholders, of any new director was approved by a vote of at least
two-thirds of the Incumbent Board, such new director shall be considered as a member of the Incumbent Board; provided, further, that no individual shall be considered a member of the Incumbent Board if such
individual initially assumed office as a result of either an actual or threatened “election contest” (as described in Rule 14a-11 promulgated under the Exchange Act) (an “Election
Contest”) or other actual or threatened solicitation of proxies or consents by or on behalf of a person other than the Board of Directors (a “Proxy Contest”) including by reason of any agreement intended to avoid or
settle any Election Contest or Proxy Contest; or 

  

	 	(iii)	 the consummation of any of the following: (A) a merger, consolidation, share exchange or reorganization
involving the Company (other than a Non-Control Transaction); (B) a complete liquidation or dissolution of the Company; or (C) the sale or other disposition of all or substantially all of the assets of
the Company to any person (other than a transfer to a Subsidiary). 

 Notwithstanding the foregoing, a Change in Control
shall not be deemed to occur solely because any person (a “Subject Person”) acquired Beneficial Ownership of more than the permitted amount of the outstanding Voting Securities as a result of the acquisition of Voting
Securities by the Company that, by reducing the number of Voting Securities outstanding, increases the proportional number of shares Beneficially Owned by such Subject Person, provided that if a Change in Control would occur (but for the operation
of this sentence) as a result of the acquisition of Voting Securities by the Company, and after such share acquisition by the Company, such Subject Person becomes the Beneficial Owner of any additional Voting Securities that increases the percentage
of the then outstanding Voting Securities Beneficially Owned by such Subject Person, then a Change in Control shall occur. 
  

	 	(b)	 “Cause” shall mean the termination of the Recipient’s employment because of the occurrence of
any of the following events, as determined by the Board in accordance with the procedure below: 

  

	 	(i)	 the failure by the Recipient to attempt in good faith to perform his or her duties or to follow the lawful
direction of the individual to whom the 

  
 5 

	 	
Recipient reports; provided, however, that the Company shall have provided the Recipient with written notice of such failure and the Recipient has been afforded at least fifteen
(15) days to cure same; 

  

	 	(ii)	 the indictment of the Recipient for, or the Recipient’s conviction of or plea of guilty or nobo
contendere to, a felony or any other serious crime involving moral turpitude or dishonesty; 

  

	 	(iii)	 the Recipient’s willfully engaging in misconduct in the performance of his or her duties (including theft,
fraud, embezzlement, securities law violations, a material violation of the Company’s code of conduct or a material violation of other material written policies) that is injurious to the Company, monetarily or otherwise, in more than a de
minimis manner; 

  

	 	(iv)	 the Recipient’s willfully engaging in misconduct unrelated to the performance of his or her duties for the
Company that is materially injurious to the Company, monetarily or otherwise; 

  

	 	(v)	 the material breach by the Recipient of any material written agreement with the Company. 

For purposes of this Section 4(b), no act, or failure to act, on the part of the Recipient shall be considered “willful” unless
done, or omitted to be done, by the Recipient in bad faith and without reasonable belief that his or her action or omission was in the best interest of the Company. Any termination shall be treated as a termination for Cause only if (i) the
Recipient is given at least five (5) business days’ written notice of termination specifying the alleged Cause event and shall have the opportunity to appear (with counsel) before the full Board to present information regarding his or her
views on the Cause event, and (ii) after such hearing, the Recipient is terminated for Cause by at least a majority of the Board. After providing the notice of termination in the foregoing sentence, the Board may suspend the Recipient with full
pay and benefits until a final determination pursuant to this Section 4(b) has been made. Notwithstanding the foregoing provisions of this Section 4(b), if the Recipient is party to an employment agreement with the Company that provides a
definition of Cause, such definition shall apply instead of the foregoing provisions of this Section 4(b). 
  

	 	(c)	 “Good Reason” shall mean (i) a reduction in the Recipient’s base salary; (ii) a
material diminution in the Recipient’s title or responsibilities; or (iii) relocation of the Recipient’s primary place of employment more than fifty miles; provided, however, that the Recipient may only terminate employment for
Good Reason by delivering written notice to the Board within ninety (90) days following the date on which the Recipient first knows of the event constituting Good Reason, which notice specifically identifies the facts and circumstances claimed
by the Recipient to constitute Good Reason, and the Company has failed to cure such facts and circumstances within thirty (30) days after receipt of such notice; and provided further, however, that if the Recipient is party to an employment
agreement with the Company that provides a definition of Good Reason, such definition shall apply instead of the foregoing provisions of this Section 4(c). 

  
 6 

	5.	 Tax Matters. 

  

	 	(a)	 83(b) Election. The recipient may make an election to include in gross income in the year of transfer
the fair market value of the Restricted LTIP Units granted hereunder in accordance with Section 83(b) of the Code. 

  

	 	(b)	 Withholding and Taxes. No later than the date as of which an amount first becomes includible in the
gross income of the Recipient for income tax purposes or subject to the Federal Insurance Contributions Act withholding with respect to the Restricted LTIP Units granted hereunder, the Recipient will pay to the Company or, if appropriate, any of its
subsidiaries, or make arrangements satisfactory to the Administrator regarding payment of, any United States federal, state or local or foreign taxes of any kind required by law to be withheld with respect to such amount. The Company may cause the
required minimum tax withholding obligation to be satisfied, in whole or in part, by withholding from Restricted LTIP Units granted to the Recipient with an aggregate value that would satisfy the withholding amount due. The obligations of the
Company under this Agreement shall be conditional on such payment or arrangements, and the Company and its subsidiaries shall, to the extent permitted by law, have the right to deduct any such taxes from any payment otherwise due to the Recipient.

 BY SIGNING THIS AGREEMENT, THE RECIPIENT REPRESENTS THAT HE OR SHE HAS REVIEWED WITH HIS OR HER OWN TAX ADVISORS THE
FEDERAL, STATE, LOCAL AND FOREIGN TAX CONSEQUENCES OF THE TRANSACTIONS CONTEMPLATED BY THIS AGREEMENT AND THAT HE OR SHE IS RELYING SOLELY ON SUCH ADVISORS AND NOT ON ANY STATEMENTS OR REPRESENTATIONS OF THE COMPANY OR ANY OF ITS AGENTS. THE
RECIPIENT UNDERSTANDS AND AGREES THAT HE OR SHE (AND NOT THE COMPANY) SHALL BE RESPONSIBLE FOR ANY TAX LIABILITY THAT MAY ARISE AS A RESULT OF THE TRANSACTIONS CONTEMPLATED BY THIS AGREEMENT. 

 

	6.	 Investment Representation; Registration. The Recipient hereby warrants and represents to and agrees with
the Company as follows: 

  

	 	(a)	 The LTIP Units issued pursuant to this Agreement will be acquired for the account of the Recipient for
investment only and not with a view to, nor with any intention of, a distribution or resale thereof, in whole or in part, or the grant of any participation therein. The Recipient acknowledges that the issuance of the LTIP Units has not been, and
will not be, registered under the Securities Act of 1933, as amended (the “Securities Act”), and the rules and regulations thereunder, or the securities or real estate syndication laws of any state or other jurisdiction, and cannot
be disposed of unless they are subsequently registered under the Securities Act and any applicable laws of states or other jurisdictions or an exemption from such registration is available. The Recipient acknowledges that the Company does not have
any intention of registering the resale of any LTIP Units issued hereunder under the Securities Act or of supplying the information necessary for the Recipient 

  
 7 

	 	
to sell any such LTIP Units; and that the Company and the Partnership shall be organized and operated so as to be exempt from registration under the Investment Company Act of 1940, as amended,
and from the provisions of that statute designed to protect investors. 

  

	 	(b)	 The Recipient also understands that the transfer of any LTIP Units issued pursuant to this Agreement will be
subject to restrictions contained in the Partnership Agreement, as well as the restrictions set forth in this Agreement. 

  

	 	(c)	 The Recipient acknowledges that (i) he or she has no obligation whatsoever to acquire the LTIP Units
issued pursuant to this Agreement, (ii) his or her acquisition of the LTIP Units issued pursuant to this Agreement is not, and will not be, in any way whatsoever a condition of continued employment with the Company or any entity affiliated with
the Company, (iii) neither the offer to the Recipient of the opportunity to acquire the LTIP Units or any shares of Stock issued pursuant to the Partnership Agreement nor this Agreement, shall be deemed to constitute a contract of employment or
to impose any obligation upon the Company or any of its affiliates to continue to employ the Recipient, and (iv) nothing stated or implied in this Agreement or in the Partnership Agreement shall be construed to abrogate, amend or otherwise
affect any rights or obligations with respect to employment which the Company or any of its affiliates or the Recipient may otherwise have by agreement or under law. 

 

	 	(d)	 The Recipient acknowledges that he or she has been furnished a copy of the Partnership Agreement, has carefully
read and understands the provisions of the Partnership Agreement, has had the opportunity to ask questions of the Company and has received answers from the Company concerning the provisions of the Partnership Agreement, and the terms and conditions
of the offering of the LTIP Units. The Recipient further acknowledges that he or she has been furnished information regarding the activities of the Company, has had the opportunity to ask questions of the Company concerning such activities, and is
satisfied with all such information and such answers as he or she has received. The Recipient acknowledges that no representation has been made by the Company otherwise by or on behalf of the Company as to any current value of the assets held by the
Company or as to any prospective return on any LTIP Units issued pursuant to this Agreement. The Recipient further acknowledges that he or she has not relied, in connection with the acquisition of the LTIP Units, upon any representations, warranties
or agreements other than those set forth in this Agreement or the Partnership Agreement. The Recipient further acknowledges that he or she provides services to the Company on a regular basis and that, in such capacity, the Recipient has access to
all such information, and has such experience and involvement in connection with the business and operations of the Company, as the Recipient believes to be necessary and appropriate to make an informed decision to accept the LTIP Units granted
pursuant to this Agreement. 

  

	 	(e)	 The Recipient acknowledges that neither the Company nor any of its affiliates is rendering any tax, legal or
financial advice or recommendation to acquire the LTIP 

  
 8 

	 	
Units issued pursuant to this Agreement. The Recipient has been informed that he or she should consult his or her own tax, legal and financial advisors to the extent the Recipient seeks advice
regarding these matters. 

  

	 	(f)	 The Recipient makes the representation regarding his or her status as an “accredited investor” as
defined in Rule 501(a) of Regulation D promulgated under the Securities Act as set forth below the Recipient’s name on the signature page hereto. 

  

	 	(g)	 So long as the Recipient holds LTIP Units, the Recipient shall disclose to the Company in writing such
information as may be reasonably requested with respect to direct or indirect ownership of any LTIP Units issued pursuant to this Agreement as the Company may deem reasonably necessary to ascertain and to establish compliance with provisions of the
Code, applicable to the Company or to comply with requirements of any other appropriate taxing authority. 

  

	 	(h)	 The Recipient shall indemnify and hold the Company harmless from and against any and all loss, cost, damage or
liability due to or arising out of a breach of any representation, warranty or agreement of the Recipient in this Agreement or any other document furnished by it to the Company in connection with this Award, including, without limitation, the
Partnership Agreement. 

  

	7.	 Miscellaneous. 

 

	 	(a)	 Entire Agreement. This Agreement, the Plan and the Partnership Agreement contain the entire
understanding and agreement of the Company and the Recipient concerning the subject matter hereof, and supersede all earlier negotiations and understandings, written or oral, between the parties with respect thereto.

 TSR results above the Threshold level and below the Maximum level shall result in a Vesting Portion that is interpolated
between the Threshold and Maximum Vesting Portions set forth on this Exhibit B. TSR results below the Threshold level will cause the Restricted LTIP Units to be forfeited to the Company without payment of any consideration by the Company, and
neither the Recipient nor any of his or her successors, heirs, assigns or personal representatives shall thereafter have any further rights or interests in such shares of Restricted LTIP Units.

 If the performance level is above Target but as of the Determination Date the Company has negative absolute
TSR with respect to the Performance Period, then the Restricted LTIP Units shall vest at the Target level as of the dates set forth in Section 2(b) of the Agreement, with the Vesting Portion in excess of Target (the “Excess
Portion”) vesting only (a) with respect to [    ]% of the Excess Portion, upon the Company’s achievement of positive absolute TSR with respect to the period beginning on the first day of the Performance
Period; and (b) with respect to the remaining [    ]% of the Excess Portion, on the later of (i) the Company’s achievement of positive absolute TSR with respect to the period beginning on the first day of
the Performance Period and (ii) the Anniversary Date; provided, however, that if the Company has not achieved positive absolute TSR with respect to the period beginning on the first day of the Performance Period as of the third anniversary of
the Determination Date, then the Excess Portion shall be forfeited to the Company without payment of any consideration by the Company, and neither the Recipient nor any of his or her successors, heirs, assigns or personal representatives shall
thereafter have any further rights or interests in such shares of Restricted LTIP Units. 
 For purposes of these calculations: 

“TSR” means the Company’s Total Shareholder Return as reported by SNL Financial or another third party judged by the Committee to be a
reputable third party, which measurement shall be confirmed by the Committee. For purposes of calculating Company’s TSR, the “starting” share price will be calculated using the average closing price for the 20-day trading period up to and including                (i.e., the first trading day of the three-year performance period), and the
“ending” share price be calculated using the average closing price for the 20-day period up to and
including                . 
 When measuring the TSR of the Company, the
calculation shall be adjusted as deemed appropriate by the Committee to reflect any change in corporate structure of the nature referenced in Section 3.4 of the Plan. 

Measurement of the TSR of the                Index
and                Index for purposes of comparison to the Company’s TSR shall be as reported by SNL Financial or another third party judged by the Committee to be
a reputable third party, which measurement shall be confirmed by the Committee. 
 “bps” shall mean basis points, each of which shall equal
1/100th of 1%.

 Exhibit 10.19 

NON-QUALIFIED STOCK OPTION AGREEMENT 

(2020 Stock Award and Incentive Plan) 

NON-QUALIFIED STOCK OPTION AGREEMENT, dated as of
                     (the “Agreement”), by and between Apartment Income REIT Corp., a Maryland corporation (the
“Company”), and                      (the “Optionee”). Capitalized terms used but not otherwise defined in
this Agreement shall have the respective meanings set forth in the Apartment Income REIT Corp. 2020 Stock Award and Incentive Plan, as amended (the “Plan”). 

WHEREAS, on                     
(the “Grant Date”) the Compensation and Human Resources Committee (the “Committee”) of the Board of Directors (the “Board”) of the Company awarded the Optionee a
non-qualified stock option, exercisable to purchase shares of the Company’s Class A Common Stock, par value $.01 per share (“Common Stock”), pursuant to, and subject to the terms and
provisions of, the Plan. 
 NOW, THEREFORE, in consideration of the Optionee’s services to the Company and for other good and valuable
consideration, the receipt and sufficiency of which are hereby acknowledged, the parties hereto agree as follows: 
  

	1.	 Number of Shares and Purchase Price. The Company hereby grants the Optionee a non-qualified stock option (the “Option”) to purchase                      shares of Common
Stock (the “Target Option Shares”) at a purchase price per share equal to                      (the
“Exercise Price”), pursuant to the terms of this Agreement and the provisions of the Plan. The number of Target Option Shares was determined by dividing
                    
by                    , which was the option valuation as determined by a third party valuation firm and approved by the Committee. The
Optionee may ultimately vest into more Target Option Shares or fewer or none as set forth in more detail in this Agreement. 

  

	2.	 Period of Option and Conditions of Exercise. 

 

	 	(a)	 Unless the Option is previously terminated pursuant to this Agreement or the Plan, the Option shall terminate
on the tenth anniversary of the Date of Grant (the “Expiration Date”). Upon the termination of the Option, all rights of the Optionee hereunder shall cease. 

 

	 	(b)	 The Option shall become exercisable as set forth in this Section 2(b) and on Exhibit A.

  

	 	(i)	 The Company’s total shareholder return (as defined in more detail on Exhibit A, “TSR”)
over the period beginning on                      and ending on
                     (the “Performance Period”), as calculated by comparison to the indices stipulated on Exhibit A to this
Agreement (and using the methodology set forth on such Exhibit A), shall be compared to the threshold, target and maximum TSR hurdles set forth on Exhibit A to determine the “Vesting Portion” (as defined on Exhibit A) of the Option
as a percentage of the Target Option Shares. Such calculations shall be 

	 	
determined by the Committee no later than                      (the date of such
determination, the “Determination Date”). Restrictions with respect to 50% of the related Vesting Portion of the Option set forth on Exhibit A shall lapse as of the later of the Determination Date and the third anniversary of the
Date of Grant (the “Vesting Date”), with the restrictions on the remaining 50% of such Vesting Portion lapsing on the fourth anniversary of the Date of Grant (the “Anniversary Date”). 

 

	 	(ii)	 Except as set forth in Section 4, each such lapse of restrictions shall occur only if the Recipient has
remained employed by the Company through the Vesting Date or the Anniversary Date, as the case may be (the “Restricted Period”). The portion of the Option that does not vest as of the Vesting Date (or the Anniversary Date, as the
case may be) based on TSR performance, shall, as of the Vesting Date (or the Anniversary Date, as the case may be), be forfeited to the Company without payment of any consideration by the Company, and neither the Recipient nor any of his or her
successors, heirs, assigns or personal representatives shall thereafter have any further rights or interests in such Option. 

  

	 	(iii)	 All determinations with respect to the calculations pursuant to this Agreement shall be made in the sole
discretion of the Committee. 

  

	3.	 Change in Control. Unexercised and unvested stock options issued hereunder shall, in addition to any
provisions relating to exercisability contained in this Agreement, become immediately fully vested and exercisable by the Optionee upon the termination of Optionee’s employment with the Company by the Company without Cause (as defined below) or
by Optionee for Good Reason (as defined below), in either case within 12 months following the occurrence of a Change of Control (as defined below), with the level of TSR performance calculated as if the date of the Change in Control was the final
day of the Performance Period, and as if the level of TSR performance as of such date was the higher of (a) target or (b) actual TSR performance as of such date, as determined in the sole discretion of the Committee in accordance with
Section 2(b) and Exhibit A. 

  

	4.	 Termination of Employment. Except as provided in this Section 4, the Option may not be exercised
after the Optionee has ceased to be employed by the Company or one of its affiliates. In the event that the Optionee ceases to be employed by the Company or one of its affiliates, the Option may be exercised following such termination, as follows:

  

	 	(a)	 if the Optionee’s termination of employment is due to his or her death or Disability (as defined below),
(i) if the Vesting Portion of the Option has already been determined pursuant to Section 2(b) above, then the unexercised portion of the Vesting Portion of the Option shall remain exercisable until the Expiration Date or (ii) unexercised
and unvested stock options issued hereunder shall become immediately fully vested and exercisable by the Optionee and the Option shall remain exercisable until the Expiration Date for the Vesting Portion of the Option Shares, with the level of TSR
performance calculated as if the date of termination was the final day of the Performance Period, and as if the level of TSR performance 

  
 2 

	 	
as of such date was the higher of (a) target or (b) actual TSR performance as of such date, as determined in the sole discretion of the Committee in accordance with Section 2(b)
and Exhibit A; 

  

	 	(b)	 if the Optionee’s termination of employment is by the Company without Cause or by Optionee for Good
Reason, in either case within 12 months following the occurrence of a Change of Control, unexercised and unvested stock options issued hereunder shall become immediately fully vested and exercisable by the Optionee as provided for in Section 3
and the Option shall remain exercisable until the Expiration Date; 

  

	 	(c)	 if the Optionee ceases to be employed by the Company or an affiliate other than under the circumstances
described in items (a) and (b) of this Section 4, the Option shall remain exercisable for a period of 90 days following such termination (but in no event later than the Expiration Date) with respect to the portion of the Option that was
otherwise exercisable as of the date of such termination (as provided for in Section 2(b)), and shall thereafter terminate; and 

  

	 	(d)	 if the Optionee’s termination is by the Company or one of its affiliates for Cause (as defined below), the
Option shall terminate immediately on the date of such termination. 

  

	5.	 Exercise of Option. 

 

	 	(a)	 The Option may be exercised only by the Optionee or, in the event of the death or incapacity of the Optionee,
the Optionee’s successor, heir or legal representative. The Option shall be exercised by delivery to the Company of (i) a written notice, substantially in the form attached hereto as Exhibit B, specify the number of shares for which
the Option is being exercised to purchase, and (ii) full payment of the Exercise Price for such number of shares being purchased (in respect of such shares, the “Total Exercise Price”), in the manner provided below, and any
transfer or withholding taxes applicable thereto. 

  

	 	(b)	 Payment of the Exercise Price for any shares being purchased shall be made as follows: 

 

	 	(i)	 The Optionee may satisfy all or any portion of the Total Exercise Price by delivery to the Company of cash, by
certified or cashier’s check, or 

  

	 	(ii)	 The Optionee may satisfy all of any portion of the Total Exercise Price by (A) assignment, transfer and
delivery to the Company, free of any liens, claims or encumbrances, of shares of Common Stock that the Optionee owns, or (B) assignment and transfer to the Company, free of any liens, claims or encumbrances, of common partnership units of AIMCO
Properties, L.P. (“OP Units”) that the Optionee owns. If the Optionee pays by assignment, transfer and delivery of shares of Common Stock, the Optionee must include with the notice of exercise the certificates for such shares of Common
Stock, either duly endorsed for transfer or accompanied 

  
 3 

	 	
by an appropriately executed stock power in favor of the Company. If the Optionee pays by assignment and transfer of OP Units, the Optionee must include with the notice of exercise a duly
executed assignment of all of the Optionee’s interest in such OP Units. For purposes of this Agreement, the value of all such shares of Common Stock delivered by the Optionee will be their Fair Market Value, and the value of all OP Units
assigned by the Optionee will be the Fair Market Value of the number of shares of Common Stock for which such OP Units are then subject to exchange upon a redemption of such OP Units. If the value of the shares of Common Stock delivered, or OP Units
assigned, by the Optionee exceeds the amount required to be paid pursuant to this Section 5, the Company will provide to the Optionee, as soon as practicable, cash or a check in an amount equal to the value of any fractional portion of a share
of Common Stock or OP Unit, and will issue a certificate to the Optionee for any whole share(s) of Common Stock or OP Units exceeding the number of shares of Common Stock or OP Units required to pay the Exercise Price for all shares being purchased;
or 

  

	 	(iii)	 At the discretion of the Administrator, the Optionee may satisfy all of any portion of the Total Exercise Price
by means of a cashless exercise procedure. 

  

	 	(c)	 Not less than 100 shares of Common Stock may be purchased at any time upon the exercise of the Option, unless
the number of shares of Common Stock so purchased constitutes the total number of shares for which the Option is then exercisable. The Option may be exercised only to purchase whole shares of Common Stock, and in no case may a fractional share of
Common Stock be purchased. The right of the Optionee to purchase shares for which the Option is then exercisable may be exercised, in whole or in part, at any time or from time to time, prior to the Expiration Date. 

 

	 	(d)	 The Company may require the Optionee to pay, prior to the delivery of any shares to which the Optionee shall be
entitled upon exercise of the Option, an amount equal to the Federal, state and local income taxes and other amounts required by law to be withheld by the Company with respect thereto. Alternatively, the Optionee may authorize the Company to
withhold from the number of shares he or she would otherwise receive upon exercise of the Option, that number of shares having a Fair Market Value equal to the minimum statutory withholding taxes with respect thereto. 

 

	 	(e)	 This Option may not be exercised unless such exercise is in compliance with the Securities Act of 1933, as
amended (the “Securities Act”) and all applicable state securities laws as they are in effect on the date of exercise and the requirements of any stock exchange or national market system on which the Common Stock may be listed at
the time of exercise. The Optionee understands that the Company is under no obligation to register, qualify or list the Option Shares with the Securities Exchange Commission, any state securities commission or any stock exchange or national market
system to effect such compliance. 

  
 4 

	6.	 Definitions. For purposes of this Agreement: 

 

	 	(a)	 “Cause” shall mean the termination of the Optionee’s employment because of the occurrence
of any of the following events, as determined by the Board in accordance with the procedure below: (i) the failure by Optionee to attempt in good faith to perform his or her duties or to follow the lawful direction of the individual to whom
Optionee reports; provided, however, that the Company shall have provided Optionee with written notice of such failure and Optionee has been afforded at least 15 days to cure same; (ii) the indictment of Optionee for, or Optionee’s
conviction of or plea of guilty or nobo contendere to, a felony or any other serious crime involving moral turpitude or dishonesty; (iii) Optionee’s willfully engaging in misconduct in the performance of his or her duties (including
theft, fraud, embezzlement, securities law violations, a material violation of the Company’s code of conduct or a material violation of other material written policies) that is injurious to the Company, monetarily or otherwise, in more than a
de minimis manner; (iv) Optionee’s willfully engaging in misconduct unrelated to the performance of his or her duties for the Company that is materially injurious to the Company, monetarily or otherwise; (v) the material breach
by Optionee of any material written agreement with the Company. For purposes of this Agreement, no act, or failure to act, on the part of Optionee shall be considered “willful” unless done, or omitted to be done, by Optionee in bad faith
and without reasonable belief that his or her action or omission was in the best interest of the Company. Any termination shall be treated as a termination for Cause only if (i) Optionee is given at least five business days’ written notice
of termination specifying the alleged Cause event and shall have the opportunity to appear (with counsel) before the full Board to present information regarding his or her views on the Cause event, and (ii) after such hearing, Optionee is
terminated for Cause by at least a majority of the Board. After providing the notice of termination in the foregoing sentence, the Board may suspend Optionee with full pay and benefits until a final determination pursuant to this Section 6(a)
has been made. Notwithstanding the foregoing provisions of this Section 6(a), if Optionee is party to an employment agreement with the Company that provides a definition of Cause, such definition shall apply instead of the foregoing provisions
of this Section 6(a). 

  

	 	(b)	 A “Change in Control” shall mean the occurrence of any of the following events:

  

	 	(i)	 an acquisition (other than directly from the Company) of any voting securities of the Company (the
“Voting Securities”) by any “person” (as the term “person” is used for purposes of Section 13(d) or Section 14(d) of the Securities Exchange Act of 1934, as amended (the “Exchange
Act”)) immediately after which such person has “beneficial ownership” (within the meaning of Rule 13d-3 promulgated under the Exchange Act) (“Beneficial Ownership”) of 50% or more of the combined voting power of
the Company’s then outstanding Voting Securities; provided, however, in 

  
 5 

	 	
determining whether a Change in Control has occurred, Voting Securities that are acquired in a Non-Control Acquisition (as hereinafter defined) shall not
constitute an acquisition that would cause a Change in Control. “Non-Control Acquisition” shall mean an acquisition (A) by or under an employee benefit plan (or a trust forming a part
thereof) maintained by (1) the Company or (2) any corporation, partnership or other person of which a majority of its voting power or its equity securities or equity interest is owned directly or indirectly by the Company or in which the
Company serves as a general partner or manager (a “Subsidiary”), (B) by the Company or any Subsidiary, or (C) by any person in connection with a Non-Control Transaction (as hereinafter
defined). “Non-Control Transaction” shall mean a merger, consolidation, share exchange or reorganization involving the Company, in which (1) the stockholders of the Company, immediately
before such merger, consolidation, share exchange or reorganization, own, directly or indirectly immediately following such merger, consolidation, share exchange or reorganization, at least 50% of the combined voting power of the outstanding voting
securities of the corporation that is the successor in such merger, consolidation, share exchange or reorganization (the “Surviving Company”) in substantially the same proportion as their ownership of the Voting Securities
immediately before such merger, consolidation, share exchange or reorganization, and (2) the individuals who were members of the Board of Directors of the Company immediately prior to the execution of the agreement providing for such merger,
consolidation, share exchange or reorganization constitute at least 50% of the members of the board of directors of the Surviving Company; 

  

	 	(ii)	 the individuals who constitute the Board as of the date hereof (the “Incumbent Board”) cease for any
reason to constitute at least 50% of the Board; provided, however, that if the election, or nomination for election by the Company’s stockholders, of any new director was approved by a vote of at least
two-thirds of the Incumbent Board, such new director shall be considered as a member of the Incumbent Board; provided, further, that no individual shall be considered a member of the Incumbent Board if such
individual initially assumed office as a result of either an actual or threatened “election contest” (as described in Rule 14a-11 promulgated under the Exchange Act) (an “Election
Contest”) or other actual or threatened solicitation of proxies or consents by or on behalf of a person other than the Board of Directors (a “Proxy Contest”) including by reason of any agreement intended to avoid or settle
any Election Contest or Proxy Contest; or 

  

	 	(iii)	 the consummation of any of the following: (A) a merger, consolidation, share exchange or reorganization
involving the Company (other than a Non-Control Transaction); (B) a complete liquidation or dissolution of the Company; or (C) an agreement for the sale or other disposition of all or substantially all of
the assets of the Company to any person (other than a transfer to a Subsidiary). 

  
 6 

 Notwithstanding the foregoing, a Change in Control shall not be deemed to occur solely
because any person (a “Subject Person”) acquired Beneficial Ownership of more than the permitted amount of the outstanding Voting Securities as a result of the acquisition of Voting Securities by the Company that, by reducing
the number of Voting Securities outstanding, increases the proportional number of shares Beneficially Owned by such Subject Person, provided that if a Change in Control would occur (but for the operation of this sentence) as a result of the
acquisition of Voting Securities by the Company, and after such share acquisition by the Company, such Subject Person becomes the Beneficial Owner of any additional Voting Securities that increases the percentage of the then outstanding Voting
Securities Beneficially Owned by such Subject Person, then a Change in Control shall occur. 
  

	 	(c)	 The Optionee’s employment will have terminated by reason of “Disability” if, in the
reasonable and good faith judgment of the Company, the Optionee is totally and permanently disabled and is unable to return to or perform his or her duties on a full-time basis. 

 

	 	(d)	 “Good Reason” means (i) a reduction in Optionee’s base salary; (ii) a material
diminution in Optionee’s title or responsibilities; or (iii) relocation of Optionee’s primary place of employment more than fifty miles; provided, however, that Optionee may only terminate employment for Good Reason by
delivering written notice to the Board within 90 days following the date on which Optionee first knows of the event constituting Good Reason, which notice specifically identifies the facts and circumstances claimed by Optionee to constitute Good
Reason, and the Company has failed to cure such facts and circumstances within 30 days after receipt of such notice; and provided further, however, that if Optionee is party to an employment agreement with the Company that provides a definition of
Good Reason, such definition shall apply instead of the foregoing provisions of this Section 6(d). 

  

	7.	 Tax Withholding. The Company shall have the power and the right to deduct or withhold, or require the
Optionee to remit to the Company, an amount sufficient to satisfy any Federal, state, and local taxes (including the Optionee’s FICA obligation) required by law to be withheld as a result of any taxable event arising in connection with the
Option, in accordance with the terms of the Plan and applicable law. 

  

	8.	 No Right to Employment. Nothing in the Plan or this Agreement shall confer on the Optionee any right to
continue in the employ of, or other relationship with, the Company, any Company Subsidiary, the Partnership or any Partnership Subsidiary or limit in any way the right of the Company, any Company Subsidiary, the Partnership or any Partnership
Subsidiary to terminate the Optionee’s employment or other relationship at any time, with or without cause. 

  

	9.	 No Rights as a Stockholder. Neither the Optionee nor any of the Optionee’s successors in interest
shall have any rights as a stockholder of the Company with respect to any shares 

  
 7 

	 	
of Common Stock subject to the Option until the date such shares are credited in electronic form in an account by the Company’s transfer agent or other designee or the date of issuance of a
stock certificate for such shares. 

  

	10.	 Miscellaneous. 

 

	 	(a)	 Entire Agreement. This Agreement and the Plan contain the entire understanding and agreement of the
Company and the Optionee concerning the subject matter hereof, and supersede all earlier negotiations and understandings, written or oral, between the parties with respect thereto. 

 

	 	(b)	 Captions. The captions and section numbers appearing in this Agreement are inserted only as a matter of
convenience. They do not define, limit, construe or describe the scope or intent of the provisions of this Agreement. 

  

	 	(c)	 Counterparts. This Agreement may be executed in counterparts, each of which when signed by the Company
or the Optionee will be deemed an original and all of which together will be deemed the same agreement. 

  

	 	(d)	 Notices. Any notice or communication having to do with this Agreement must be given by personal delivery
or by certified mail, return receipt requested, addressed, if to the Company or the Committee, to the attention of the Legal Department of the Company at the principal office of the Company and, if to the Optionee, to the Optionee’s last known
address contained in the personnel records of the Company. 

  

	 	(e)	 Succession and Transfer. Each and all of the provisions of this Agreement are binding upon and inure to
the benefit of the Company and the Optionee and their successors, assigns and legal representatives; provided, however, that the Option granted hereunder shall not be transferable by the Optionee (or the Optionee’s successor or legal
representative) other than by will or by the laws of descent and distribution and may be exercised during the lifetime of the Optionee, only by the Optionee or by his or her guardian or legal representative. 

 

	 	(f)	 Amendments. Subject to the provisions of the Plan, this Agreement may be amended or modified at any time
by an instrument in writing signed by the parties hereto. 

  

	 	(g)	 Governing Law. This Agreement and the rights of all persons claiming hereunder will be construed and
determined in accordance with the laws of the State of Maryland without giving effect to the choice of law principles thereof. 

  

	 	(h)	 Plan Controls. This Agreement is made under and subject to the provisions of the Plan, and all of the
provisions of the Plan are hereby incorporated by reference into this Agreement. In the event of any conflict between the provisions of this Agreement and the provisions of the Plan, the provisions of the Plan shall govern. By signing this
Agreement, the Optionee confirms that he or she has received a copy of the Plan and has had an opportunity to review the contents thereof.
