Why Their Letter Is Stronger
A landlord's scrutiny lands on the evaluation behind the letter, not on its formatting. Someone who has treated you for months can describe your history, how your symptoms have moved over time, and how your animal fits into your treatment. A single 20-minute visit cannot produce that depth, however genuine it is.
If a verification call comes, a treating clinician has real records to refer to. That is the difference between a letter that survives a challenge and one that merely looks correct.
There is also a cost argument. Many clinicians write a letter as part of care you are already receiving, so if your sessions are covered by insurance the letter may cost you nothing.
How to Ask
Raise it in a session rather than by email, and be specific. Vagueness is what produces a vague letter.
- Say you are requesting a reasonable accommodation for housing
- Ask for it on letterhead, with their license number and contact details
- Say roughly when you need it, and whether a landlord may call to verify
- Name the animals you need covered, with species
- Ask for a PDF you can forward, and a paper copy if you want one
Then give them the substance. Describe in concrete terms what changes when the animal is present and what happens when it is not — sleep, appetite, panic frequency, ability to leave the house, whatever is true for you. That specificity is what makes a letter read as a clinical opinion rather than a template.
What the Letter Must Contain
Check it against this list before you send it anywhere. A missing license number is a two-minute fix beforehand and a real problem afterwards.
- Their license type, license number and issuing state
- The date it was written
- A statement that they evaluated you
- A statement that you have a condition substantially limiting a major life activity
- A statement that the animal is part of your treatment
- Each animal named, with species
- Their signature and direct contact details
Notice what is not on the list. Your diagnosis does not need to be stated, and a housing provider generally cannot require it. A letter that discloses more medical detail than necessary is not a stronger letter — it is simply less private.
If They Say No
It happens, and it is usually not about you. Some practices have a blanket policy against writing any letters — housing, court, employment — because of liability concerns or because they do not want to be drawn into disputes between tenants and landlords.
Ask two follow-up questions. First, whether anyone else in the practice writes them, since the policy is often practice-wide rather than individual. Second, whether they would be willing to confirm your treatment history to another professional, which can help if you do go elsewhere.
If the answer is still no, an online service is a reasonable fallback. What you are buying is access to a professional licensed in your state, and exactly the same rules apply to their letter as to your therapist's.
Which Professionals Can Write One
- Psychologists
- Psychiatrists
- Licensed clinical social workers
- Licensed marriage and family therapists
- Licensed professional counsellors
- Psychiatric nurse practitioners
The credential type matters far less than the license state. License title conventions differ between states, so the letters after a name vary depending on where you live. What a housing provider verifies is the license number against the public state register.
If You Don't Have a Therapist Yet
It is worth considering whether you want one, separately from the housing question. If you do, starting with care and letting the letter follow is usually better value than buying a letter now and paying for therapy separately three months later.
Low-cost routes exist: community mental health centres and federally qualified health centres use sliding-scale fees, university counselling is free to enrolled students, and employee assistance programs often cover a set number of sessions.
If documentation is genuinely all you need, that is what we sell — $129 for up to two animals, charged only after a provider approves you, with your signed PDF delivered within 10 minutes of that approval.
If You've Just Moved States
This is the situation that trips up people who already have a therapist, and it is worth checking before you need the letter.
For a letter to do its job, the professional has to be licensed in the state where you live, because that is the register your new landlord checks. A therapist licensed only in the state you left cannot write you a letter that survives verification at your new address, even though they know your history best.
Some clinicians hold licenses in several states, and some states participate in compacts that extend practice privileges, so ask rather than assuming. If they cannot help, ask whether they will summarise your treatment history for a new provider. A professional in your new state who has that background can write something far more specific than one starting from nothing.
Frequently Asked Questions
Can my therapist write an ESA letter?
Yes, if they are licensed in your state. Any licensed mental health professional can — psychologist, psychiatrist, licensed clinical social worker, marriage and family therapist, licensed counsellor, or psychiatric nurse practitioner.
Will my therapist charge extra for an ESA letter?
Often not. Many write one as part of care you are already receiving, so if your sessions are covered by insurance your extra cost can be nothing. Some charge a small administrative fee. It is worth simply asking.
How long does my therapist need to have treated me?
There is no federal minimum. In practice, a clinician who has seen you over a period can write a more detailed letter than one who has met you once, which is what makes it more defensible.
What if my therapist won't write one?
Ask whether a colleague in the practice will — a refusal is often practice-wide policy rather than personal. If not, an online service licensed in your state is a reasonable fallback.
Does my therapist have to state my diagnosis?
No, and a landlord generally cannot require it. The letter needs to say you have a condition that substantially limits a major life activity and that the animal is part of your treatment, not what the condition is called.
Can my therapist be in a different state?
For the letter to work, they need to be licensed in the state where you live, because that license is what a housing provider verifies. If you have moved recently, this is worth checking.
Is an online letter as good as one from my own therapist?
It is valid, provided a licensed professional in your state genuinely evaluated you. It is not as detailed, because a treating clinician has months of history to draw on. If you have that option, use it.
Booking and screening are free. You're only charged after a licensed provider approves you.
