Can a property require medical documentation, or require a letter from a “doctor only” to prove my disability?

A property cannot require detailed medical information, nor can a property require the documentation come only from a doctor or physician. According to HUD, If the disability is “not readily apparent” or known by the housing provider, like PTSD, Autism, or TBI, the housing provider may ask for “reliable documentation” to verify the disability. According to HUD, a reliable source could be “a doctor or other medical professional, a peer support group, a non-medical service agency, or a reliable third party who is in a position to know about the individual’s disability.” So, a property cannot require the reliable source be a doctor, however, a doctor could be a reliable source.
