Short answer
It's a letter signed by a licensed mental health professional in your state, for your reasonable accommodation request at your rental. With it you can ask to live with your animal in no-pet housing, ask for exceptions to breed or weight rules, and ask your landlord to waive pet fees. Your landlord reviews the request. If it's approved, your animal can live with you even where the rules say no pets; since HUD's 2025-2026 changes, whether a landlord may still charge pet fees or deposits depends on your state and the type of housing. Your letter is dated, shows as current in our free letter verification for one year from its date, and your landlord can check it free, 24/7, with its MPC ID and your last name.
What it's for
An ESA Housing Letter supports your reasonable accommodation request at your rental. It's signed by a licensed mental health professional in your state. With it you can ask your landlord:
- to let you live with your animal in no-pet housing;
- for exceptions to breed or weight rules;
- to waive pet fees.
What your landlord does with it
Your landlord reviews your request. Since HUD's 2025-2026 changes, what a landlord has to allow depends more on your state, the type of housing and whether your animal is trained. What HUD's changes mean, pet fees and deposits and ESA laws by state.
