APPENDIX K

24 CFR 200.926

Minimum Property Standards for Property which is not

Multifamily or Care-type Property

The following portions of 24 C.F.R. Part 200 have been

included for the convenience of the users of this handbook. These

provisions establish procedures for the construction of one and two

family dwellings and reference standards found in the Appendices of

this handbook.

200.926 Minimum property standards for one- and two-family

dwellings.

\(a\) Construction standards.

\(1\) Applicable structures. The standards identified or

contained in this section and 200.926 and 200.926a-200.926e

shall apply to single family detached homes,

duplexes, triplexes and to living units in a structure

where the units are located side-by-side in townhouse

fashion.

\(2\) Applicability of standards to new construction. The

standards referenced in paragraph (a)(1) of this section

are applicable to:

\(i\) Structures approved for insurance or other benefits

prior to the start of construction, including

approval under the direct endorsement process

described in 203.5 of this chapter;

\(ii\) Structures which are approved for insurance or

other benefits based upon participation in an

insured warranty program;

\(iii\) Structures which are insured as new construction

based upon a Certificate of Reasonable Value issued

by the Veterans Administration.

4910.1

\(b\) Conflicting standards. The requirements contained in

200.926d do not preempt local or State standards, nor do they

alter or affect a builder\'s obligation to comply with any

local or State requirements. However, a property shall be

eligible for benefits only if it complies with the

requirements of this subpart, including any referenced

standards. When any of the requirements identified in

200.926c are in conflict with a partially accepted local or

State code, the conflict will be resolved by the HUD Field

Office servicing the jurisdiction in which the property is to

be located.

\(c\) Standard for evaluating local or State building codes. The

Secretary shall compare a local building code submitted under

200.926(d) or a State code to the list of construction

related areas contained in 200.926a.

\(1\) A local or State code will be accepted if it regulates

each area and subarea on the list. However, for seismic

design, ASCE 7-88, is mandatory.

\(2\) A local or State building code will be partially accepted

if it regulates most of the areas on the list provided,

however, that no code may be partially accepted if it

fails to regulate subareas in more than one of the major

areas. The major areas are: fire safety, light and

ventilation, structural loads, foundation systems,

materials, standards, construction components, glass,

mechanical, plumbing and electrical. See 200.926a.

\(3\) For purposes of this paragraph, a local or State code

regulates an area or subarea if it establishes a standard

concerning that area or subarea.

\(d\) Code selection. Any materials required to be submitted under

this section must be submitted by the time the lender or other

interested party applies for mortgage insurance or other

benefits.

\(1\) Jurisdictions without previously accepted building codes.

The following submission requirements apply to lenders

and other interested parties in jurisdictions without

building codes, jurisdictions with building codes which

previously have never been submitted for acceptance and

jurisdictions with building codes which previously have

been submitted for acceptance and have not been accepted

or partially accepted by the Secretary.

\(2\) Requirements for Accessibility to Physically Disabled

People

The HUD Field Office will advise project sponsors as to

the extent accessibility will be required for new

construction of one- and two-family dwellings on a

project-by-project basis.

\(i\) Technical Standards

See HUD, Minimum Property Standards, 4910.1 See 24

CFR Part 40.

\(3\) Variations to standards.

\(i\) New materials and technologies.

See 200.926d(d). Alternatives, nonconventional

or innovative methods and materials shall be

equivalent to these standards in the areas of

structural soundness, durability, economy of

maintenance or operation and usability.

\(ii\) Variation procedures.

Variations from the requirements of any standard

with which the Department requires compliance shall

be made in the following ways:

\(A\) For a particular design or construction method

to be used on a single case or project, the

decision is the responsibility of the Field

Office. Headquarters concurrence is not

required.

\(B\) Where a variation is intended to be on a

repetitive basis, a recommendation for a Local

Acceptable Standard, substantiating data, and

background information shall be submitted by

the Field Office to the Director, Office of

Manufactured Housing and Regulatory Functions.

\(iii\) Variances which require individual analysis and

decision in each instance are not considered as

repetitive variances even though one particular

standard is repeatedly the subject of variation.

Such variances are covered by 200.926d(a)(3)(ii)(A).

4910.1

\(b\) General acceptability criteria.

\(1\) Real estate entity.

The property shall comprise a single plot except

that a primary plot with a secondary plot for an

appurtenant garage or for other use contributing to

the marketability of the property will be

acceptable provided the two plots are in such

proximity as to comprise a readily marketable real

estate entity.

\(2\) Service and facilities.

\(i\) Trespass.

Each living unit shall be one that can be used

and maintained individually without trespass

upon adjoining properties, except when the

windowless wall of a detached dwelling is

located on a side lot line. A detached

dwelling may be located on a side lot line if:

\(A\) Legal provision is made for permanent

access for the maintenance of the

exterior portion of the lot line wall,

and

\(B\) The minimum distances from the dwelling

to the dwellings on the abutting

properties are not less than the sum of

the side yard distances computed as

appropriate for the type of opposing

walls. (Minimum distance 10 ft.)

\(ii\) Utilities.

Utility services shall be independent for each

living unit, except that common services such

as water, sewer, gas and electricity may be

provided for living units under a single

mortgage or ownership. Separate utility

service shut-off for each unit shall be

provided. For living units under separate

ownership, common utility services may be

provided from the main to the building line

when protected by an easement or convenant and

maintenance agreement acceptable to HUD, but

K-14

\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_

4910.1

shall not pass over, under or through any

other living unit. Individual utilities

serving a living unit may not pass over, under

or through another living unit under the same

mortgage unless provision is made for repair

and maintenance of utilities without trespass

or when protected by an easement of covenant

providing permanent access for maintenance and

repair of the utilities. Building drain

cleanouts shall be accessible from the

exterior where a single drain line within the

building serves more than one unit.

\(3\) Site conditions.

\(i\) The property shall be free of those

foreseeable hazards and adverse conditions

which may affect the health and safety of the

occupants or the structural soundness of the

improvements, or which may impair the

customary use and enjoyment of the property.

The hazards include toxic chemicals,

radioactive materials, other pollution,

hazardous activities, potential damage from

soil or other differential ground movements,

ground water, inadequate surface drainage,

flood, erosion, or other hazards located on or

off site. The site must meet the standards

set forth at 24 CFR Part 51, and HUD Handbook

4910.1, Section 606 for termite and decay

protection.

\(ii\) When special conditions exist or arise during

construction which were unforeseen and which

necessitate precautionary or hazard mitigation

measures, the HUD Field Offices shall require

corrective work to mitigate potential adverse

effects from the special conditions as may be

necessary. Special conditions include rock

formations, unstable soils or slopes, high

ground water level, springs, or other

conditions which may adversely effect a

property. It shall be the builder\'s

responsibility to assure proper design,

construction and satisfactory performance

where they are present.

\(i\) A site design shall be provided which includes

an arrangement of all site facilities

necessary to create a safe, functional,

healthful, durable and energy efficient living

environment.

\(ii\) These site design standards are applicable

only in communities which have not adopted

criteria for site development applicable to

one and two family dwellings.

\(iii\) Single family detached houses situated on

individual lots located on existing streets

with utilities need not comply with the

requirements of 200.926d(c)(2), (3) and

(4)(ii).

\(2\) Streets.

\(i\) Existing or proposed streets on the site shall

connect to private or public street and shall

provide all-weather access to all building for

essential and emergency use, including access
