Landlord cannot insist on a specific form from healthcare providers. They must rely on the ESA letter written by the provider if it meets HUD’s requirements.

Physicians are one type of licensed healthcare professional permitted to write ESA letters. For red flags, please see this article: https://esadoctors.com/dont-be-scammed-fake-esa-letters/

You cannot qualify for an ESA by “registering it”. The only way to qualify for an ESA is to have a signed letter from a licensed healthcare professional. HUD allows landlords to demand an ESA letter as proof that a tenant has a valid emotional support animal. Please see this link for more info: https://esadoctors.com/esa-letter/

My landlord says that there is only one esa allowed per apartment but my wife has an ESA and I need one as well, is what she’s telling me true?

You can submit it to your landlord to let them know that you have an emotional support animal.

There is no time limit but most ESA owners either already have their ESA or plan to get one soon when they get their ESA letter.
