HIGHLIGHTS
- Adult children can usually live with a qualifying 55+ parent—if the community allows it.
- Federal law only requires one 55+ resident in 80% of occupied homes.
- Minimum ages for the younger household member are set by the community, not by law.
- If the 55+ parent dies or moves out, the right to stay depends on the rules and state law.
- Always confirm occupancy rules in the CC&Rs before buying.
In most active adult communities, an adult child (18 and older) can live with a parent as long as at least one resident is 55 and older and the community’s rules allow the extra occupant. Whether a grown child is moving back after a divorce, a job change, or to help out, the arrangement is often possible, though it is never guaranteed.
The real answer lives in the community’s governing documents. This guide explains how to read them, what the federal 80/20 rule does and does not promise, how long a grown child may stay, and what happens if the 55-and-older parent moves out or passes away.
How the Age Rules Actually Work
Active adult communities operate under the federal Housing for Older Persons Act (HOPA), which requires at least one resident 55 and older in at least 80% of occupied homes. Vacant homes don’t count against the community. HOPA is a narrow exemption to the Fair Housing Act’s protection for “familial status” (households with children under 18), and it does not permit discrimination by race, color, religion, sex, disability, or national origin.
An adult child living with a parent 55 and older is therefore a community policy question layered on top of a federal floor. Federal law doesn’t forbid the arrangement; it sets the minimum standard. The community’s CC&Rs and HOA policies set every concrete rule about who else may live in the home is set by the community’s CC&Rs and HOA policies.
Can Your Adult Child Live With You? (The Short Answer)
Usually yes for an adult child 18 and older, provided a household member is 55 and older, and the community’s governing documents permit the additional occupant. Federal law sets no minimum age for the other people in a qualifying home, but communities can and do set their own secondary age floors, and those minimum ages vary from one community to the next.
Living there is not automatic. Some communities cap how many people may live in a home, require HOA approval, or limit the length of stay. The distinction between owning and occupying matters. Anyone can own a home in an active adult community, but who may live there is restricted. Confirm the specifics with the HOA and get any approval in writing.

What About the 80/20 Rule and the 20%?
At least 80% of occupied homes must have a resident 55 and older, and up to 20% may have no resident 55 and older. That 20% is a ceiling, not an entitlement. Federal law lets each community “determine the age restriction, if any,” for the non-qualifying units, so a community may require that 100% of residents be 55 and older.
In practice, the 20% is usually a management cushion reserved for a younger spouse, an inheritance situation, or an approved exception. It is not open capacity a family can claim on demand. Assuming the 20% means an adult child is automatically allowed is one of the most common misreads of the rule.

How Long Can an Adult Child Stay?
It depends on the community’s governing documents. Some communities allow an adult child to live there permanently. Others treat longer stays as “guest” visits with day caps and require written approval. Many communities track guest-days per year, so the line between visiting and residing can be strict.
State law may set a floor. California, for example, requires developments for residents 55 and older to permit under-55 temporary residency for at least 60 days per year. The practical takeaway: Get the length-of-stay policy in writing before counting on permanent residency.
What Happens If the 55+ Parent Moves Out or Passes Away?
Federal HOPA is silent on this scenario. The home shifts into the up-to-20% non-qualifying group, so a surviving under-55 occupant doesn’t by itself endanger the community’s status. But whether the adult child may stay is decided by the community’s rules and state law, not federal law.
Some CC&Rs allow the under-55 occupant to remain. Others use a survivorship window, often a set number of months, before requiring them to move. California offers a statutory example: a “qualified permanent resident” (generally 45 and older) is entitled to continue occupancy after the senior’s death or prolonged absence. The same statute creates a pathway for a disabled child or grandchild of any age.
If an adult child may one day need to remain, read the survivorship and inheritance language before buying and ask about state protections.
Minor Children and Grandkids: A Quick Note
Minors (under 18) generally cannot be permanent residents in an active adult community. That is the core of the HOPA exemption, which allows communities to exclude households with children under 18. Communities commonly allow visits for a set number of days, and some offer narrow grace periods for a custody change or similar situation. Policies vary widely.

How to Confirm the Rules Before You Buy
Before committing to a community where an adult child may need to live, take these steps:
- Read the CC&Rs and bylaws for occupancy, guest, and minimum-age language.
- Ask the HOA directly: Can an adult child live here full-time? At what minimum age? For how long?
- Get any exception in writing (caregiver, disability, hardship).
- Ask how age is verified. HOPA requires age verification at least once every two years using reliable documentation.
- Check whether your state adds protections beyond the federal floor, especially for survivorship.
- Work with an agent who knows the specific community’s rules. 55places Partner Agents can help find communities that fit a multigenerational household.
Frequently Asked Questions
Can a 30-year-old live in a 55+ community with their parent?
In many communities, yes, as long as at least one resident is 55 and older and the HOA allows additional adult occupants. Some communities require formal approval or cap how long an additional occupant may stay, so confirming the policy before moving in is essential.
How long can my adult child live with me in a 55+ community?
There’s no federal time limit. The community’s governing documents decide whether an adult child qualifies as a permanent occupant or a capped guest. Some allow full-time residency while others limit stays to a certain number of days per year. Confirm the length-of-stay policy in writing.
Can my child inherit and live in my 55+ community home?
A child can usually inherit the home, because age restrictions apply to who lives in the home, not who owns it. Whether the child can then live in the home depends on their age, the community’s rules, and state law. California, for example, protects certain “qualified permanent residents” (generally 45 and older) who may remain after a senior’s death.
Can someone under 55 buy a home in a 55+ community?
Yes. Age restrictions apply to who lives in the home, not who owns it. A person under 55 can purchase a home as an investment or for a qualifying family member, but the occupant still has to meet the community’s age and occupancy rules.
