The 55+ rulebook nobody actually reads.

HOPA, the 1995 amendment to the Fair Housing Act, lets a community restrict by age only if it meets three tests at once: at least 80% of occupied units must have at least one resident aged 55 or older, the community must publish and follow policies demonstrating its intent to operate as 55+ housing, and it must comply with HUD’s age-verification requirements. The near-universal misreading is that the other 20% is "reserved" for younger buyers. It is not. The 80% is a floor the community must stay above, not a quota of spaces held below it — and nothing obligates a community to admit anyone under 55 at all.

In fact, many communities are stricter than the federal floor: some require every unit to have a 55+ occupant, and each association’s own governing documents control which version applies. That is the recurring theme of this whole page — the statute sets the outer boundary, but the community’s documents set your actual rules, and I read them before my clients sign.

The good news most couples want first: HOPA requires only one occupant per unit to be 55 or older, so in most 55+ communities a younger spouse can live there without issue. The sharp edge is the 62+ community — a different exemption entirely, where every resident must qualify and a couple with one member under 62 can be refused outright. And some 55+ associations set internal rules tighter than the federal minimum, so "my spouse is 51" is a documents question, not a settled yes.

Grandchildren: welcome as guests, not as residents. Nearly all age-restricted communities allow under-age visitors on a limited basis, with covenants typically permitting temporary stays somewhere between two weeks and ninety days per year — the specific cap, amenity access, and registration requirements live in the CC&Rs and vary widely. The 80/20 provision governs permanent residents, not visitors; the guest policy is where the real limits live.

A 55+ community must be able to prove its status, not just claim it: HUD requires verification of the 80% occupancy floor through reliable surveys and affidavits, with age attested in leases, applications, or signed certifications. Florida made one change buyers misread constantly — effective July 1, 2020, the state eliminated the requirement for 55+ communities to register with the Florida Commission on Human Relations every two years. That did not deregulate anything: the underlying obligation to run a resident age survey every two years remains, because it is what keeps the federal exemption defensible.

Why should a buyer care about the association’s compliance hygiene? Because the exemption belongs to the community, not to you — and a community that gets sloppy about its surveys and policies is a community whose age restriction is legally vulnerable. Part of my diligence in any 55+ purchase is confirming the association actually operates its exemption, not just advertises it.

This is the rule Northeast Florida families keep learning the hard way — including in a 2026 dispute at a Jacksonville-area community in Oakleaf, where the attorney’s summary was exact: an under-55 heir can absolutely inherit the property and take title, but no owner under 55 may occupy the home unless the community’s requirements are met. The widespread assumption that the "20% slack" automatically entitles a younger heir to move in is wrong — the community is not required to spend its buffer on anyone.

The estate-planning consequence: a 55+ home passes down as an asset your heirs may only be able to rent out (subject to the community’s rental rules — another documents question) or sell, not live in. Families who plan around the house as a future residence for a younger generation are planning around a right that does not exist. I raise this before contract with every 55+ buyer, because the honest time to hear it is at the purchase, not at the estate reading.
