Can My Primary Doctor Write an ESA Letter?
Usually yes, and one state names physicians, PAs and nurses in statute. The specialty is not the constraint: licensure, direct knowledge and willingness are.
Some do, and they check two things only. What a housing provider may lawfully confirm, what triggers a closer look, and how to run the check on yourself first.
Three routes cost nothing or close to it, and each has a real catch. What free actually gets you, what it never gets you, and how to pick by the deadline you have.
