Age-restricted communities are common in manufactured housing, and the exemption that makes them lawful is narrower and more specific than most operators realise. It rests on three separate tests in federal regulation, one of which names particular marketing language as evidence working against you.

This article summarises federal regulation at 24 CFR Part 100 Subpart E. It is not legal advice. State and local law may impose additional requirements, and the consequences of losing the exemption are significant. Have your policies, marketing materials and verification procedures reviewed by counsel familiar with fair housing law in your jurisdiction.

What the Exemption Actually Is

Start with what you are relying on.

The Fair Housing Act prohibits discrimination on the basis of familial status, which broadly means discriminating against households with children. An age-restricted community is doing exactly that, and it operates lawfully only within a specific exemption.

Under 24 CFR § 100.304, the familial status provisions do not apply to housing intended and operated for persons 55 years of age or older. For an alleged violation occurring on or after 28 December 1995, housing qualifies where it complies with section 807(b)(2)(C) of the Fair Housing Act and with three regulations: 24 CFR 100.305, 100.306 and 100.307.

The exemption is not something a community registers for or receives in advance. To qualify for it, the community must satisfy the applicable statutory and regulatory requirements, and be able to show that it does.

There is no question about whether this sector is covered. Section 100.304 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 a manufactured housing community operating under one set of community rules sits within that.

Test One: The 80 Percent Rule

Section 100.305 sets the occupancy threshold. At least 80 percent of occupied units must be occupied by at least one person 55 years of age or older.

Three details in that sentence do more work than operators expect.

"Occupied units," not all units. Unoccupied units are excluded from the calculation. The regulation is explicit that a community can qualify where there are unoccupied units, provided at least 80 percent of the occupied ones meet the test. For a community with vacant lots, and most have some, that matters.

"At least one person." The threshold is one qualifying occupant per unit, not all of them. A household where one occupant is 58 and another is 40 counts toward the 80 percent.

Temporarily vacant counts, conditionally. The regulation treats a temporarily vacant unit as occupied where the primary occupant resided there during the past year and intends to return on a periodic basis. Where the unit is temporarily vacant, the test is whether at least one of the occupants immediately before it was vacated was 55 or older. Seasonal residents are common in this sector, and this is the provision that accommodates them.

The Employee Exception

The regulation also provides that a community may qualify where there are units occupied by employees under 55, and family members residing in the same unit, provided those employees perform substantial duties related to the management or maintenance of the community.

For manufactured housing that is a practical provision. On-site managers living in the community are normal, and this is what keeps a manager's household from counting against you.

Other Circumstances the Section Addresses

Section 100.305 sets out several situations in which a community may still qualify despite units not occupied by a person 55 or older. The employee provision above is one. The section addresses others, and the calculation is more nuanced than a simple headcount.

If your community is anywhere near the threshold, read the section in full or have someone read it for you. Working from a summary, including this one, is not sufficient when the margin is thin.

The Fractional Unit Rule

Where applying the 80 percent calculation produces a fraction of a unit, the regulation provides that the unit is counted among those which must be occupied by at least one person 55 or older. The fraction rounds against you. Run the number rather than estimating.

What the Regulation Allows for the Remaining Units

Section 100.305 allows a community to determine the age restriction, if any, for units not occupied by at least one person 55 or older, subject to the community continuing to satisfy the intent requirements in § 100.306.

Whatever the community decides, its published policies and its actual practices both remain relevant to qualification. So the decision needs to be written down and then followed.

What You Cannot Do During the Transition

Section 100.305 contains a specific prohibition connected to its transition provision. A community relying on that provision may not evict, refuse to renew leases, or otherwise penalise families with children in order to achieve occupancy of at least 80 percent of occupied units by at least one person 55 or older.

The broader process of establishing or maintaining 55+ status can raise additional fair housing issues, particularly where occupancy policies affect families with children. Those questions should be reviewed against the community's specific circumstances and applicable law rather than resolved by reference to this provision alone.

Test Two: Intent, and the Language That Can Undermine It

Section 100.306 requires that the community publish and adhere to policies and procedures demonstrating its intent to operate as housing for persons 55 or older.

The regulation lists factors considered relevant to whether that requirement has been met, including the manner in which the community is described to prospective residents, any advertising designed to attract them, lease provisions, written rules, regulations, covenants, deed or other restrictions, the maintenance and consistent application of relevant procedures, and public posting in common areas of statements describing the community as housing for persons 55 or older.

Read that list as a document audit. Every item is something you either have in writing or do not.

Section 100.306(b) adds a specific warning. The regulation states that phrases such as "adult living," "adult community," or similar statements in any written advertisement or prospectus are not consistent with the intent to operate as housing for persons 55 or older.

If your written advertising or prospectus uses that language, review it against § 100.306(b). Review signage and other public-facing descriptions as well, because the regulation separately treats how the community describes itself to prospective residents and public postings in common areas as relevant evidence of intent. Those are different routes to the same concern, and both are worth checking.

And subsection (c) on inherited documents. Where language in a deed or other community documents is inconsistent with 55+ intent, the regulation provides that HUD shall consider documented evidence of a good faith attempt to remove that language, alongside other evidence of intent.

Two things follow. Inherited language does not automatically sink you. But the good faith attempt has to be documented, which means the fix has to be recorded rather than merely intended. If you acquired a community with problematic covenants, start the removal process and keep the paper trail.

Test Three: Verification You Can Produce

Section 100.307 reframes how to think about the whole thing. The community must be able to produce, in response to a complaint filed under the Act, verification of compliance with the 80 percent requirement through reliable surveys and affidavits.

It must develop procedures for routinely determining the occupancy of each unit, including identifying whether at least one occupant is 55 or older, and those procedures may form part of a normal leasing or purchasing arrangement.

And those procedures must provide for regular updates, through surveys or other means, of the initial information supplied by occupants — at least once every two years.

The section goes further than that summary, addressing what documentation is adequate and what happens where occupants decline to cooperate. If you are building or rebuilding your survey process, read the whole section.

The framing matters. This is not an administrative filing. It is evidence, and the moment you need it is the moment somebody has complained. A community that has operated as 55+ for fifteen years without a current survey is relying on an exemption it may not be able to demonstrate.

What This Means in a Manufactured Housing Community

Four things are specific to this sector rather than to age-restricted housing generally.

1. Occupancy records are not title records:
   The resident may own the home, but the verification process needs to establish who occupies each unit or homesite. In a manufactured housing community that means the occupancy record should not be confused with the title record for the home, and your survey has to be built around the former.

2. Home sales in place involve two considerations at once:
   A sale can require the operator to consider both the incoming resident's eligibility under the community's policies and the effect of occupancy changes on the community's ongoing compliance. Those processes should be coordinated, while remaining subject to any state-law limits on transfer or residency approval, which in some states are specific and enforceable.

3. Your rules document is one of the listed factors:
   Section 100.306 names written rules and regulations among the evidence of intent. Communities frequently have rules that were adopted decades ago and never revisited. Our 50-state index of manufactured housing community laws covers the procedures states require for adopting and amending community rules, which is what you will need to follow to change them.

4. Signage is physical and permanent:
   Unlike a line in a document, an entrance sign is usually cast or carved, and replacing it is a small capital item that operators put off. If a review of your public-facing descriptions turns up a problem there, it needs a budget line rather than an edit.

What to Do This Quarter

Six things, in order of how quickly they can be done.

1. Audit your written materials. Search your advertising, prospectus, website, brochures, rules, lease and signage for "adult" and review each use in context. Pay particular attention to written advertising and prospectuses, where § 100.306(b) specifically addresses phrases such as "adult living" and "adult community."

2. Find your last age verification survey. If you cannot find one, or it is more than two years old, that is the item to deal with first.

3. Calculate your current percentage properly, using occupied units as the denominator, applying the provisions in § 100.305 rather than a rule of thumb, and rounding fractions against yourself.

4. Check your rules and lease describe the community as housing for persons 55 years of age or older, in those terms.

5. Confirm common area postings exist, since public posting is one of the listed factors.

6. Put the two-year survey in a compliance calendar with a named owner. Recurring obligations that live in someone's memory are the ones that lapse, and this one is your evidence.

Conclusion

The HOPA exemption provides the federal fair housing framework that allows qualifying communities to operate as housing for persons 55 years of age or older without violating the Act's familial status provisions. It depends on three tests being satisfied simultaneously.

Three things worth carrying away. The 80 percent calculation has more structure than it appears. Occupied units are the denominator, temporarily vacant units can count, several other circumstances are separately addressed, and fractions round against you.

The intent requirement is essentially a document and communications audit, and § 100.306(b) names specific language as inconsistent with the required intent when it appears in a written advertisement or prospectus.And the verification survey is evidence rather than paperwork. Section 100.307 frames it as what you produce when a complaint is filed, which means the time to have it is before you need it. If you take one action from this, search your own materials for the word "adult" and read each use in context. It takes ten minutes and it is the most likely thing on this list to need attention.

Frequently Asked Questions

1. What is the 80 percent rule for 55+ communities?
Under 24 CFR § 100.305, at least 80 percent of occupied units must be occupied by at least one person aged 55 or older. Unoccupied units are excluded from the calculation. A temporarily vacant unit can count where the primary occupant lived there in the past year and intends to return. The section also addresses other circumstances, including units occupied by under-55 employees performing substantial management or maintenance duties.

2. Can a 55+ community describe itself as an adult community?
Section 100.306(b) states that phrases such as "adult living," "adult community," or similar statements in any written advertisement or prospectus are not consistent with the intent to operate as housing for persons 55 or older. The regulation separately treats how a community describes itself to prospective residents and public postings in common areas as relevant evidence of intent, so signage and other public-facing descriptions are also worth reviewing.

3. How often does a 55+ community have to verify residents' ages?
At least once every two years. Section 100.307 requires procedures for routinely determining each unit's occupancy, including whether at least one occupant is 55 or older, with regular updates through surveys or other means at least biennially. The community must be able to produce verification through reliable surveys and affidavits in response to a complaint.

4. What happens to the other 20 percent of units?
The community decides, within limits. Section 100.305 allows a community to determine the age restriction, if any, for units not occupied by a person 55 or older, subject to continuing to satisfy the intent requirements in § 100.306. Whatever is decided should be written into published policies and followed in practice.

5. Does HOPA apply to manufactured housing communities?
Section 100.304 defines a housing facility or community as any dwelling or group of dwelling units governed by a common set of rules, regulations or restrictions. A manufactured housing community operating under one set of community rules sits within that definition.
