Exhibit 10.1

INCREASE CERTIFICATE

April 15, 2016

Reference is made to that certain Credit Agreement, dated as of January 14, 2016
(as amended or otherwise modified, the “Credit Agreement”), among Rexford
Industrial Realty, L.P., a Maryland limited partnership (“Borrower”), Rexford
Industrial Realty, Inc., a Maryland corporation (“Parent”), PNC Bank, National
Association, as Administrative Agent, and each lender from time to time party
thereto. Capitalized terms used and not defined herein shall have the meaning
ascribed to such terms in the Credit Agreement.

Pursuant to Section 2.12 of the Credit Agreement, Borrower, Parent,
Administrative Agent, and the Lenders party hereto agree to make additional
Loans to Borrower in the aggregate amount of up to $100,000,000, which
additional Loans may be requested by Borrower and made by each Lender party
hereto during the period from the date hereof to the earlier of (a) May 16, 2016
and (b) the date on which Lenders make any such additional Loans to Borrower
(the “Increase Availability Period”).

Each Lender party hereto hereby agrees to make additional Loans to Borrower
under the Credit Agreement during the Increase Availability Period in an amount
not to exceed the amount of Maximum Additional Loans for such Lender set forth
on Schedule 1 attached hereto, subject to the following conditions:

(a)Borrower shall not make more than one request for any additional Loans and
such request shall be in the minimum amount of $25,000,000;

(b)If Borrower shall request additional Loans in an amount less than the
aggregate amount of Maximum Additional Loans set forth on Schedule 1 attached
hereto, then Lenders shall make such additional Loans pro rata based upon the
amount of such Lender’s Maximum Additional Loans set forth on Schedule 1
attached hereto;

(c)The representations and warranties of Borrower and each other Loan Party
contained in Article VII of the Credit Agreement or any other Loan Document, or
which are contained in any document furnished at any time under or in connection
with the Loan Documents, shall be true and correct in all material respects
(without duplication of any materiality qualifiers therein) on and as of the
date of such additional Loans, except to the extent that such representations
and warranties specifically refer to an earlier date, in which case they shall
be true and correct in all material respects (without duplication of any
materiality qualifiers therein) as of such earlier date, and except that the
representations and warranties contained in subsections (a) and (b) of Section
7.05 of the Credit Agreement shall be deemed to refer to the most recent
statements furnished pursuant to clauses (a) and (b), respectively, of Section
8.01 of the Credit Agreement;

(d)No Default shall exist, or would result from such additional Loans or from
the application of the proceeds thereof; and

(e)Administrative Agent shall have received a Loan Notice in accordance with the
requirements of the Credit Agreement.

The obligations of Lenders to make additional Loans hereunder shall terminate
upon the expiration of the Increase Availability Period.

--------------------------------------------------------------------------------

During the Increase Availability Period, Borrower shall pay to Administrative
Agent, for the account of each Lender, an unused fee equal to 0.20% times the
Maximum Additional Loans for such Lender set forth on Schedule 1 attached
hereto. Such unused fee shall be due and payable on the last day of the Increase
Availability Period.

Schedule 2.01 of the Credit Agreement is hereby replaced with Schedule 1
attached hereto. If Borrower requests additional Loans in an aggregate amount
less than $100,000,000, then Schedule 1 attached hereto shall be updated to
reflect such lesser amount of additional Loans and such updated Schedule 1 shall
replace Schedule 2.01 of the Credit Agreement.

The Loan Documents are ratified and affirmed by each of Borrower and Parent and
shall remain in full force and effect.

This Increase Certificate shall constitute one of the Loan Documents.
