The law behind an ESA request
An emotional support animal request is a reasonable-accommodation request, and almost every argument about one comes back to a handful of rules. These pages set out what those rules say, where they come from, and which of them the May 2026 HUD rescission moved.
8 pages below. If your question turns on the rules where you live, the state pages answer it for your state, and five states have a rule that changes the answer to almost everything here.
- The Fair Housing ActThe statute did not change in 2026. How one agency enforces it did, and the difference between those two things is the whole story.
- Section 504 of the Rehabilitation ActThe most under-used provision in this area, and the one least affected by what happened in May 2026.
- The ADA and animals in publicThe statute people cite at the wrong moment, and the one that now shapes housing enforcement as well.
- The Air Carrier Access ActThe clearest answer in this whole area, and the one most often reported incorrectly.
- The reasonable accommodation standardFour words in the statute carry nearly every dispute in this area. Here is what each of them does.
- Undue burden and fundamental alterationThe most frequently claimed defence and the least frequently evidenced one.
- The private right of actionThe part of the Fair Housing Act that HUD cannot change, and the one that now matters most.
- State fair housing agenciesThe route that did not narrow, and the one most people do not know exists.
Every page carries the date it was last reviewed. This is a plain description of what the law says, not legal advice.
