Under 24 CFR Part 100 § 100.201a, HUD formally adopts several editions of the ANSI/ICC A117.1 accessibility standards—covering years 1986 through 2009—by incorporating them into the Fair Housing Act design-and-construction rules at §§ 100.201 and 100.205. This means those technical documents carry the same regulatory weight as the rule's own text, and compliance with the relevant edition is measured against the incorporated standard's specifications.

Operators subject to the Fair Housing Act's design-and-construction requirements under 24 CFR Part 100 § 100.201a should be aware that the applicable ANSI/ICC A117.1 edition—ranging from the 1986 through 2009 versions—functions as binding technical guidance for accessible and usable building features. Compliant developers and property managers typically identify which incorporated edition applies to their project and obtain the full standard directly from ANSI or ICC at the contact information listed in § 100.201a.

Under 24 CFR Part 100 § 100.201a, the accessibility standards incorporated by reference set the technical benchmarks that covered housing must meet, which means tenants experiencing accessibility barriers may have grounds to raise a Fair Housing Act design-and-construction concern. Tenants can explore options such as filing a complaint with HUD, raising a violation as a defense in relevant proceedings, or contacting a local tenant-rights organization for general information about how these incorporated standards apply.
