Emotional support animals in basement flats and accessory units
Housing situations
This is the situation where the federal exemption genuinely applies, and where state law usually decides the question instead.
Why this setting is different
A basement flat, garage conversion or granny annexe is usually part of a building the owner lives in. The Fair Housing Act does not reach owner-occupied buildings of four units or fewer, so unlike almost every other page on this site, the starting position here may genuinely be that the federal Act does not apply.
Working out whether the exemption applies
- Does the owner actually live in the building now? Not previously, and not next door.
- How many units are there in total, counting the owner unit? Four or fewer.
- Is the unit in the same building, or a separate structure on the same lot? A detached unit can change the analysis and is worth asking about.
- Was a letting agent used to find you? That generally forfeits the separate single-family exemption, though not this one.
State law is usually the answer here
Most states have their own fair housing statute, and many have narrower exemptions than the federal Act or none at all. A basement flat exempt federally can be fully covered by state law, and since May 2026 the state route is the one with enforcement behind it anyway. Check your state page before accepting that the exemption ends the matter.
Even where the exemption applies
The advertising provision of the Act applies regardless of any exemption, so a listing that excluded disabled tenants or assistance animals is a problem for the owner even if the tenancy itself is exempt. And an exempt owner can still agree. A short, calm request to somebody who lives upstairs succeeds more often than a legal argument would.
Common questions
- My landlord lives upstairs. Am I out of luck?
- Federally, possibly. Under your state statute, quite possibly not, and that is the question worth asking first.
