Washington sets no statewide cap on pet deposits or pet fees (RCW 59.18.260), and Seattle caps total move-in costs at one month's rent. Any deposit still needs a written lease and a signed move-in checklist, a nonrefundable fee must be labeled nonrefundable in the lease (RCW 59.18.285), and deposit balances are due back within 30 days with a full and specific statement (RCW 59.18.280(1)).
This post gives you a numbered checklist to run before you charge anything for a pet. Then it covers how to label each charge, how to handle pet damage at move-out, and what changed for emotional support animals now that HUD has pulled back its federal guidance.
What should I check first before charging a pet deposit or fee in Washington?
Run this seven-step checklist before you write a number into the lease. Each item is explained in the sections that follow.
- Is it a pet, or a request for a service or support animal? Charges for pets and charges for assistance animals follow different rules.
- Is your lease in writing, with the withholding terms spelled out? No written lease means no collectible deposit.
- Is each charge labeled correctly? Use one of three labels: refundable deposit, nonrefundable fee, or monthly pet rent.
- Does a city rule cap your total move-in costs? Seattle does, at one month's rent.
- Have you completed and signed a move-in condition checklist? The tenant must get a copy.
- Will you offer installments if the tenant asks? In many cases you must.
- Can you deliver a documented, itemized statement within 30 days of move-out?
Items 2, 5 and 7 carry the money penalties. Skipping the checklist can cost you the whole deposit, and a missed deadline can cost you the deposit and then some.
How much can I charge for a pet deposit or pet fee in Washington?
There's no statewide dollar limit, so the amount is up to you unless a city caps it. Washington has no statewide security deposit cap under RCW 59.18.260, and Seattle caps total move-in costs at one month's rent. Check your local rules before you set a pet charge on top of the base deposit.
The state does regulate how you collect it. If a tenant pays a deposit or security for performance, the lease must be in writing and state the terms and conditions under which the deposit may be withheld. You also can't collect any deposit unless you give the tenant a written checklist at move-in describing the condition and cleanliness of the premises, fixtures and appliances. Both you and the tenant sign and date it, and the tenant gets a copy. For a pet, add specific lines for flooring, carpet, doors, screens and any yard or fence. That gives you a baseline to compare against at move-out.
The penalty for skipping the checklist is steep. If you collect a deposit without providing the written checklist, you're liable to the tenant for the amount of the deposit, and the prevailing party may recover court costs and reasonable attorneys' fees.
Installments matter too. For leases of three months or longer, the tenant may elect to pay deposits, nonrefundable fees and last month's rent in three consecutive equal monthly installments. In all other cases the tenant may elect two. You aren't required to allow installments if the total of deposits and nonrefundable fees is no more than 25% of the first full month's rent and you don't require last month's rent at the start. You can't charge a fee or interest because the tenant chooses installments. Refusing a written installment request can cost you a statutory penalty of one month's rent plus reasonable attorneys' fees. The source for all of this is RCW 59.18.610.
What's the difference between a pet deposit, a pet fee and pet rent?
A pet deposit is refundable security, a pet fee is a one-time charge you keep, and pet rent is a recurring monthly charge. Washington treats the first two very differently, and mislabeling is the most common way to lose a fee. The table shows how each is handled.
| Charge | What it is | Washington rule |
|---|---|---|
| Refundable pet deposit | Security held against pet damage and unpaid charges | Needs a written lease with withholding terms and a signed move-in checklist (RCW 59.18.260). Return it, or send an itemized statement with documentation, within 30 days (RCW 59.18.280(1)). |
| Nonrefundable pet fee | One-time charge you keep whether or not there's damage | It can't be designated as a deposit, and the lease must be in writing and clearly say the fee is nonrefundable. If the lease doesn't say so, the fee must be treated as a refundable deposit. (RCW 59.18.285) |
| Monthly pet rent | Recurring charge for keeping the animal | It's not a deposit or a fee. I didn't verify how the 2025 rent-increase limits apply to it, so check RCW 59.18.700–.730 before adding or raising it at renewal. |
| Damage charge | Actual cost to repair pet damage | No deposit may be withheld for wear resulting from ordinary use of the premises. (RCW 59.18.260) |
One trap sits between a fee and a deposit. At move-out the tenant must restore the premises except for ordinary wear, and the tenant can't be charged for normal cleaning if they've paid a nonrefundable cleaning fee. That's in RCW 59.18.130. If you label a pet fee as cleaning, you've probably given up the right to deduct routine cleaning from the deposit.
How do I deduct pet damage from the deposit in Washington?
Send the tenant a full and specific written statement of what you're keeping, with documentation, plus any refund, within 30 days (RCW 59.18.280(1)). Miss that, and the consequences are severe. If you fail to give the statement, documentation and any refund within the time limit, you're liable to the tenant for the full amount of the deposit. The court may award up to two times the deposit for intentional refusal unless you show circumstances beyond your control prevented you from complying within 30 days, or that the tenant abandoned the premises. In any action by the tenant to recover the deposit, the prevailing party also gets costs and a reasonable attorneys' fee.
Pet damage is where documentation matters most. Use dated photos and the signed move-in checklist, and keep invoices for repairs. Carpet is the usual fight: you can't withhold for carpet cleaning unless you document wear beyond ordinary use. A pet that was in the unit for a three-year tenancy leaves wear and tear that's hard to separate from damage, so photograph and itemize specific spots.
Rent or other charges owed are a different matter. The checklist and documentation requirements don't apply when you withhold for reasons unrelated to damage, such as unpaid rent or other charges. A nonrefundable fee can't be pulled into the deposit pool, and a deposit shouldn't be treated as a fee.
Can I charge a pet deposit or fee for a service animal or emotional support animal in Washington?
Don't charge a pet deposit or fee for a trained service animal, and treat emotional support animal (ESA) requests case by case, because federal guidance on ESAs changed in 2025–2026 and Washington's position hasn't been clearly updated. A trained assistance animal is not a pet for pet-charge purposes.
Here's what changed. HUD's 2020 notice said housing providers may not charge pet fees or deposits for assistance animals. A HUD memo reaffirmed the September 2025 rescission of HUD's 2013 and 2020 guidance on assistance animals, including ESAs. That memo is dated May 22, 2026. It says requests to waive pet policies for animals trained to perform disability-related services are presumptively reasonable, while requests for untrained ESAs are not, and HUD no longer expects housing providers to extend accommodations to untrained ESAs automatically. It also cites a Louisiana federal district court decision. In that case, waiving a generally applicable pet fee for an ESA was held neither reasonable nor necessary. That decision isn't binding in Washington.
Washington's own statute hasn't been rewritten by the HUD memo. RCW 49.60.222 makes it an unfair practice to refuse reasonable accommodation in rules, policies, practices or services when necessary to give a person with a disability equal opportunity to use and enjoy a dwelling, and it names the use of a trained dog guide or service animal. I didn't find statute text that settles whether Washington requires you to waive pet charges for an untrained ESA. A federal agency's enforcement priorities also don't stop a tenant from filing a state complaint or a private lawsuit.
So for a self-managing landlord, the practical approach is this. Waive pet deposits and fees for trained service animals. For ESA requests, don't issue a flat "no" and don't ignore the request. Respond promptly in writing, handle each request individually, and get a lawyer's read before you deny one or charge a pet fee over a documented request. Whatever the animal, you can still deduct actual damage through the 30-day statement process above, the same way you would for any tenant's damage.

Is there a legal limit on pet deposits in Washington?
No. Washington has no statewide cap on security deposits or pet deposits under RCW 59.18.260. Seattle caps total move-in costs at one month's rent, so check your city's rules before adding a pet charge. Whatever you charge, you need a written lease and a signed move-in checklist before collecting any deposit.
Can I make a pet fee nonrefundable in Washington?
Yes, but only if the written lease clearly says the fee is nonrefundable (RCW 59.18.285). You also can't call it a deposit or put it into the deposit. If the lease doesn't specify that it's nonrefundable, the fee has to be treated as a refundable deposit, and you'd owe an accounting for it within 30 days of move-out.
How long do I have to return a pet deposit in Washington?
30 days after the tenancy ends. You must return the deposit or send a full and specific written statement of what you're keeping, with documentation (RCW 59.18.280(1)). If you miss the deadline, you can be liable for the full deposit. A court may award up to two times the deposit if the refusal was intentional, and the prevailing party recovers attorneys' fees.
Do I have to accept an emotional support animal if my lease says no pets?
It depends, and this area is unsettled. HUD rescinded its 2013 and 2020 assistance-animal guidance, and its May 22, 2026 memo says it will focus on individually trained animals. RCW 49.60.222 still bars refusing reasonable accommodations for tenants with disabilities, and I couldn't find statute text that settles untrained ESAs. Respond in writing, assess each request on its own facts, and consult an attorney before denying one.
