How to Get an ESA Letter in Washington
An ESA letter is the only assistance animal document with a basis in housing law. Here is who can write one in Washington, how long it takes, what it must contain, and what a Washington landlord is allowed to ask you for.
Yes — from a provider licensed in Washington.
There is no Washington ESA registry and no Washington certificate. What works is a letter from a healthcare provider licensed here, confirming you have a disability and a disability-related need for the animal, followed by a written request to your housing provider.
What Makes Getting a Letter in Washington Different
Washington names assistance animals in its Law Against Discrimination and also has a misrepresentation penalty, so both sides of the question are legislated. Seattle adds a municipal civil rights office. A letter from a Washington-licensed provider is well supported here.
No waiting period. A letter can be written as soon as the evaluation is done.
Only five states — Arkansas, California, Iowa, Louisiana and Montana — require a minimum relationship period, and Washington is not one of them. That is about timing, not about standards. The clinician still has to actually evaluate you, and still has to be licensed in Washington.
Who Can Write an ESA Letter in Washington?
Any of the following, provided they hold a current Washington license and have actually evaluated you. The categories are the same nationwide; the exact license title varies from state to state, so check the credential against the Washington licensing board rather than against a list on a seller’s website.
| Provider | What it means |
|---|---|
| Psychiatrist | A medical doctor (MD or DO) specialising in mental health. Can also prescribe. |
| Psychologist | Doctoral-level (PhD, PsyD or EdD). Assesses and treats, does not usually prescribe. |
| Licensed clinical social worker | Master’s-level, usually LCSW. Writes a large share of ESA letters. |
| Licensed marriage and family therapist | Master’s-level, usually LMFT. |
| Licensed professional counselor | Master’s-level. Called LPC, LPCC, LCPC or LMHC depending on the state. |
| Nurse practitioner | A psychiatric-mental health NP (PMHNP) treating you for the condition. |
| Your primary care physician | Can write one if they treat you and are willing to speak to the need. |
The licensing trap. The provider must be licensed in the state where you are, not where they are. A therapist licensed in a neighbouring state cannot write you a valid Washington letter just because the appointment happened over video. This is the single most common reason letters get rejected, and telehealth services are where it usually goes wrong. Interstate compacts exist, but the main one covers only doctoral-level psychologists — it does not cover the social workers and counselors who write most ESA letters.
What a Washington Landlord Can Ask For
Washington has its own provision at RCW § 49.60.222 on top of the federal Fair Housing Act, so a Washington landlord is working from two sources rather than one. Read the citation yourself — the Washington code portal is linked at the foot of this page.
They can ask for this
Documentation from a licensed provider confirming a disability and a disability-related need for the animal. If your disability is not obvious, they can ask you to establish it. They can ask reasonable follow-up questions.
They cannot ask for this
Your diagnosis. Your medical records. A registration number or certificate. A specific form of their own design. A pet fee or deposit for an approved assistance animal. Access to your provider without your consent.
What Your Washington Letter Must Contain
Eight things. A letter missing any of them gives a Washington landlord a reason to come back to you, and every round trip costs you time.
| # | Element |
|---|---|
| 1 | Provider letterhead with real, checkable contact details |
| 2 | License number |
| 3 | Washington named as the state of licensure |
| 4 | A date |
| 5 | A statement that you have a disability — without naming the diagnosis |
| 6 | A statement that the animal is needed because of it |
| 7 | The animal identified |
| 8 | The provider’s signature |
Item 3 is the one that catches people in Washington. The full checklist covers each element and the six mistakes that get letters refused.
Ready to get a Washington letter?
Start with a provider licensed here. If you already see someone, ask them first — it is usually free and always the strongest version of this document.
The Penalty for a Fake ESA Letter in Washington
Washington penalises false documentation. RCW § 49.60.222 addresses misrepresentation of an assistance animal. This is one more reason a real evaluation is the cheaper option: a genuine letter and a purchased one cost about the same, and only one of them carries risk.
How to Get an ESA Letter in Washington: 4 Steps
Start With the Provider You Already Have
If you see a therapist, counselor or physician in Washington, ask them first. They already know your history, the letter costs you nothing extra, and it is the most defensible version of this document.
If You Are Not in Treatment, Find a Washington-Licensed Provider
Telehealth is fine. Check the license before you pay: the clinician must be licensed in Washington, and you can verify that against the Washington licensing board’s public register. Walk away from any service that will not name the clinician in advance.
Check the Letter Against the Eight Elements
Read it before you send it anywhere. If something is missing, ask the provider to reissue it. That is a normal request and a real provider will not object.
Send a Written Accommodation Request
This is the step that creates your landlord’s legal duty, and the step most people skip. Short, dated, attaching the letter, asking for a written response. Template here.
What an ESA Letter in Washington Costs
If you already have a provider, usually nothing beyond a normal appointment. If you do not, an evaluation with a Washington-licensed clinician typically runs from about $100 to $200, and insurance sometimes covers the appointment even when it does not cover the letter. Anything advertised as instant, guaranteed, or approved-before-payment is describing a product rather than a clinical service.
Guaranteed approval is the clearest warning sign there is. A clinician who guarantees the outcome before evaluating you is telling you the evaluation is not real. That is also the letter most likely to fail when a Washington landlord checks the license. How to spot the rest.
If Your Washington Landlord Says No
Get the reason in writing first. Then work out whether it is a lawful refusal or not — many are not. Washington State Human Rights Commission handles the state route, and HUD takes complaints from Washington through the HUD Northwest Regional Office (Region X). Both are free and neither needs a lawyer. The order to escalate in.

Questions
ESA Letters in Washington: Common Questions
How long does it take to get an ESA letter in Washington?
Washington sets no minimum waiting period, so it can be as quick as a single appointment plus the provider’s turnaround — often a few days. What it cannot be is instant, because a real evaluation has to happen first.
Can an online ESA letter work in Washington?
Yes, if the clinician is licensed in Washington and genuinely evaluates you. Telehealth is a legitimate way to practise. The problem is not that a service is online, it is that many online services use providers licensed elsewhere, which produces a letter a Washington landlord can reject.
Does my Washington ESA letter expire?
No law sets an expiry date. In practice housing providers often treat a letter more than a year old as stale, and asking for a current one is usually reasonable. A quick follow-up appointment is the simplest way to refresh it.
Do I need to register my animal in Washington as well?
No. There is no Washington registry and no federal one. Registration numbers, certificates and ID cards carry no legal weight anywhere in the United States, and a Washington landlord cannot require one.
Can my Washington landlord charge a pet deposit for an approved ESA?
An approved assistance animal is not a pet, so pet fees and deposits have not historically applied. HUD narrowed federal enforcement in May 2026, so the answer now leans harder on Washington law. See pet rent and deposits.
Can a doctor in another state write my Washington letter?
Generally no. The provider needs to be licensed where you live. A letter from an out-of-state clinician is the most common reason a Washington request gets refused, and it is worth checking the license number before you pay anyone.
