Can an HOA tell you how many people can live in your house?

Can an HOA limit how many people live in your home? How occupancy limits collide with Fair Housing familial-status protection, the two-per-bedroom guideline, and when a single-family-use clause is enforceable.
The short answer
An HOA can enforce a reasonable occupancy limit, but it cannot use one to keep out families with children, and it usually cannot invent a stricter cap than the law allows. Occupancy is one of the trickiest areas in community-association law because two forces pull against each other: an association's legitimate interest in preventing overcrowding and preserving a residential, single-family character, and the federal Fair Housing Act's protection of families with children. A limit tied to the real capacity of the home - bedrooms, septic, building code - is generally defensible. A limit that functions to exclude households with kids is not, no matter how it is worded. This guide is about how many people may occupy a home; for the broader question of what an HOA can dictate about the inside of your house, see our guide on whether an HOA can control what you do inside your house.
Single-family use clauses are about use, not headcount
Most CC&Rs contain a 'single-family residential use' restriction, and owners often misread it as a cap on the number of people. In practice these clauses are aimed at use - they prevent running a duplex, a boarding house, or a commercial operation out of a home, and they define what counts as a 'family' or a 'single housekeeping unit.' They are generally enforceable to stop a home from being chopped into separate rented rooms or used as a business. What they cannot reliably do is set a low numeric cap on residents, because the definition of 'family' has been narrowed by fair-housing law: a definition that excludes unrelated people or limits a household in a way that screens out children invites a discrimination challenge. So a single-family clause can stop a true rooming-house use, but it is a weak basis for telling a married couple they have too many kids.
Where the Fair Housing Act draws the line
Familial status - the presence of one or more children under 18 in a household - is a protected class under the federal Fair Housing Act (42 U.S.C. section 3604). That means an occupancy rule that has the purpose or effect of discriminating against families with children is unlawful, even if it never mentions children. The U.S. Department of Housing and Urban Development has long treated a standard of two persons per bedroom as a reasonable general starting point when evaluating occupancy limits (the guidance from HUD's 1991 'Keating' memorandum), but it is only a rebuttable rule of thumb, not a hard ceiling - the size of the bedrooms, the configuration of the home, the age of the children, and local code all factor in. An HOA that tries to impose, say, a flat limit of two people per home, or that counts a nursery against a family, is on dangerous ground. Our guide on fair housing and HOAs explains how familial-status and other protected-class rules apply across community rules.
When an occupancy limit is legitimate
Occupancy limits are not automatically illegal - the key is that they must be tied to an objective, health-and-safety basis rather than to who the occupants are. The most defensible limits track an external standard: a local building or housing code occupancy formula (many jurisdictions follow a square-footage-per-occupant rule drawn from the International Property Maintenance Code or a local equivalent), the rated capacity of a septic or water system, or a state law setting a maximum. When an HOA's cap mirrors the municipal code, it is usually enforcing the same number the city would, which is far easier to defend than a number the board picked on its own. By contrast, an occupancy rule the association made up, that is stricter than local code and that bears no relationship to the home's physical capacity, is the kind most likely to be challenged as a pretext for excluding families. Boards are generally on safest ground deferring to the applicable building and health codes rather than legislating headcount themselves.
What to do if your HOA challenges your household size
If an HOA tells you that too many people are living in your home, first find out exactly what rule it is relying on - a single-family-use clause, an occupancy number in the rules, or a claim that you are violating local code - and ask for it in writing. Check whether the limit is tied to the building or health code or is simply a number the board chose; a cap stricter than local code that effectively targets a family with children is vulnerable. If you believe the rule discriminates based on familial status, you can raise that directly with the board, and you have the option of filing a complaint with HUD or your state fair-housing agency - our guide on how to file a complaint against an HOA covers those routes. Respond to any violation notice in writing and use your community's hearing process rather than ignoring it, and keep the exchange documented; an occupancy dispute that turns into a fair-housing claim will turn heavily on the written record of what the board demanded and why.
How OurHOA helps
Occupancy disputes go wrong when a board enforces a vague 'single-family' clause or a homemade headcount in a way that looks - even unintentionally - like it is aimed at families with children. OurHOA helps small self-managed communities keep their governing documents and rules organized and applied evenly, so a board can point to the actual use restriction or the local code it is enforcing, document any notice and hearing, and avoid drifting into the kind of subjective, family-targeting enforcement that creates fair-housing liability.
OurHOA is the friendly, affordable way self-managed communities keep dues, records, and reminders in one place. See how it works.
