Overview
An emotional support animal (ESA) letter is a signed statement from a licensed mental-health clinician confirming that an animal provides therapeutic benefit for a diagnosed mental-health condition. Under the federal Fair Housing Act (FHA), a valid ESA letter forces landlords — including most no-pet buildings — to allow the animal and to waive pet rent, pet deposits, and breed or weight restrictions.
Treatment
A legitimate ESA letter requires: 1) a real telehealth or in-person evaluation with a clinician licensed in your state (LCSW, LPC, psychologist, psychiatrist, MD, DO, NP, or PA who does mental-health work), 2) a documented DSM-5 mental-health diagnosis (anxiety, PTSD, major depression, panic disorder, etc.), 3) the clinician's professional opinion that an ESA is part of the treatment plan. Clindle issues ESA letters after a real online evaluation for $50, includes a PDF on Clindle letterhead with the clinician's license number and state, and offers a free re-issue at 12 months if your address changes.

Are ESA letters that cost $29 or come without a visit legitimate?
No. Any site that promises a letter in minutes with no video evaluation is not compliant with HUD guidance and landlords routinely reject those letters. A legitimate letter requires a real clinical evaluation.
How long is an ESA letter valid?
There is no federal expiration, but most landlords require a letter dated within the last 12 months. Clindle re-issues yours free at the 12-month mark.
Does an ESA letter work for air travel?
No. The DOT removed ESA protections from air travel in 2021. Airlines now treat ESAs as regular pets. Only psychiatric service dogs (a separate category) still fly free in the cabin.
Can my landlord ask for my diagnosis?
No. Under HUD guidance, the landlord may ask for the ESA letter and verify the clinician's license, but they cannot demand your specific diagnosis or medical records.
