The exemption is narrow, and the narrowness is the most important fact on this page. 24 CFR 100.301(a) disapplies "the provisions regarding familial status in this part," and nothing else. Race, color, national origin, religion, sex and disability protections apply in full, as do the Act's accessibility requirements and its obligation to allow reasonable accommodations. A community that treats "55+" as a general license to select its residents has misread the exemption it is relying on.
The 80 percent test is about units and it is a floor, not a ceiling. 24 CFR 100.305(a) requires that "at least 80 percent of its occupied units must be occupied by at least one person 55 years of age or older." Two consequences follow that surprise people. First, the arithmetic runs on occupied units, so as many as 20 percent of households may have no resident aged 55 or over and the community still qualifies. Second, an occupied unit includes a temporarily vacant one under 100.305(b)(2), where "the primary occupant has resided in the unit during the past year and intends to return on a periodic basis," which is how a seasonal absence is handled. Separate carve-outs at 100.305(e) cover units held by employees of the community who are under 55 and by people needed to provide a reasonable accommodation to a resident with a disability.
What happens in the other 20 percent is the community's call, not the statute's. 24 CFR 100.305(h) says each facility or community "may determine the age restriction, if any, for units that are not occupied by at least one person 55 years of age or older," provided it still meets the intent requirement. This is where the practical questions live: whether a surviving spouse under 55 may stay, whether an adult child may inherit and occupy, whether a grandchild may live with a resident. None of those is answered by federal law. They are answered by the recorded documents and the community's own policies, and 100.306(d) makes clear that a qualifying community "may allow occupancy by families with children" if it still satisfies the occupancy and intent rules. Read the documents before buying, because they, not the regulation, decide.
Intent has to be published and adhered to, and advertising is evidence. 24 CFR 100.306(a) requires policies and procedures demonstrating the intent to operate as 55-or-over housing, and lists what HUD weighs: how the community is described to prospective residents, its advertising, lease provisions, written rules and recorded restrictions, whether procedures are consistently applied, actual practice, and public posting in common areas. Paragraph (b) then rules out a particular vocabulary: phrases such as "adult living," "adult community" or similar statements in written advertising "are not consistent with the intent that the housing facility or community intends to operate as housing for persons 55 years of age or older." A community advertising itself as an adult community is producing evidence against its own exemption.
Age has to be verified, on a schedule. 24 CFR 100.307 requires the community to be able to produce verification of compliance through reliable surveys and affidavits, to have procedures for determining the occupancy of each unit, and to update them "at least once every two years." Acceptable documentation includes a driver's license, birth certificate, passport, immigration card, military identification, comparable official documents, or a signed certification by a household member aged 18 or older that at least one occupant is 55 or older.
The 62-or-over exemption is a different and stricter animal. 24 CFR 100.303(a) covers housing "intended for, and solely occupied by, persons 62 years of age or older," with narrow carve-outs for residents in place on September 13, 1988, reserved vacant units, and under-62 employees performing substantial management or maintenance duties. There is no 80 percent allowance. HUD's own example makes the difference concrete: where John is 62 and Mary is 59, a community wanting to keep the 62-or-over exemption must refuse them, though renting to them "might qualify for the '55 or over' exemption in § 100.304."
Who this reaches is wider than a subdivision. 24 CFR 100.304(b) defines a housing facility or community as any dwelling or group of dwelling units governed by a common set of rules, regulations or restrictions, and its examples include a condominium association, a cooperative, a property governed by a homeowners' or resident association, a municipally zoned area, a leased property under common private ownership, a mobile home park, and a manufactured housing community. A portion of a single building does not count.
