Can You Have Pets in Apartments in Washington? What Renters Should Know

Can you have pets in apartments in Washington? In most cases, yes — but only because your landlord has chosen not to say no. The Washington State Residential Landlord-Tenant Act outlines that tenants can keep pets unless the rental agreement states otherwise, meaning landlords have the right to restrict pets but must explicitly state this in the lease. That single rule shapes everything else about pet ownership in a Washington rental, from deposits to breed limits to what happens if your building suddenly changes its policy.

This guide covers what Washington law actually allows around pet deposits and fees, breed and weight restrictions, service animal and emotional support animal rights, mid-lease policy changes, and what to do if a landlord refuses your pet outright.

Can a Landlord Ban Pets in Washington

Washington State has specific regulations about pets in rental properties, and the Residential Landlord-Tenant Act outlines that tenants can keep pets unless the rental agreement states otherwise, meaning landlords have the right to restrict pets but must explicitly state this in the lease. A landlord can legally run a strict no-pets building. What they cannot do is spring a pet ban on you after you’ve already signed a lease that’s silent on the issue, since the restriction has to be written into the agreement from the start.

Most Washington landlords who do allow pets handle the details through a pet addendum rather than leaving it to a single sentence in the lease. These addendums typically outline acceptable pets, breed or size restrictions, and noise or behavior guidelines, and some leases require written permission from the landlord before you introduce a pet into the property. Skipping that step and moving a pet in anyway can put you at risk of eviction or other lease penalties, so it’s worth getting any verbal approval from a property manager confirmed in writing.

Standard no-pet clauses are usually written with cats and dogs in mind, which leaves plenty of gray area for smaller or less conventional animals. Before assuming a “no pets” apartment is off-limits for every kind of animal, check whether your exotic pet is even legal to own in Washington in the first place, since state wildlife rules apply on top of whatever your lease says. Many renters have had success keeping low-key species like pet insects, a pet chameleon, or even a small hermit crab habitat in buildings that technically ban dogs and cats, though it’s always safer to get explicit sign-off in writing rather than assume a loophole applies.

Pet Deposits and Pet Fees: What Washington Allows

Washington landlords can charge tenants for having pets, but every pet-related charge falls under rules in the state’s Residential Landlord-Tenant Act, and the type of charge determines what the landlord can keep, how the money must be handled, and what documentation is required. Tenants also have the right to pay these charges in installments rather than as a lump sum, and assistance animals are exempt from pet charges entirely.

Washington law draws a sharp line between three types of pet-related charges:

Charge Type	Refundable?	Typical Amount	Key Rule
Pet Deposit	Yes	Counts toward total security deposit	Must be returned within 21 days if no damage occurs
Nonrefundable Pet Fee	No	$200–$500 one-time	Lease must state in writing that it’s nonrefundable
Pet Rent	No (ongoing)	$25–$50 per month	No statutory cap, but must appear in the lease

A nonrefundable pet fee is a one-time charge you pay for the privilege of keeping a pet, and for it to be legally nonrefundable the lease must be in writing and clearly state that the fee is nonrefundable — if the lease fails to specify that, the charge defaults to a refundable deposit that the landlord must handle under standard deposit rules. One-time pet fees typically range from $200 to $500, though nothing in state law caps the amount, while pet rent is a recurring charge added to the base rent each month, usually between $25 and $50 per pet.

Important Note: Washington lawmakers have proposed a cap on pet damage deposits under Senate Bill 6064, which would set the limit at $150, but as of late 2025 the bill was still pending passage rather than enacted law. Confirm the current status before assuming a $150 cap applies to your lease.

Whatever you pay, your landlord has 21 days after you move out to return your deposit, and if any portion is kept, must explain why — the rental unit must be restored to the same condition as when you moved in, and a deposit cannot be used to cover normal wear and tear or damage that existed before you moved in. A low-maintenance pet that’s less likely to scratch floors or chew baseboards can make it considerably easier to get your full deposit back at move-out.

Washington also requires a paper trail for your unit’s condition. Complete a move-in checklist and keep a copy, since the move-in/move-out checklist required under RCW 59.18.260 protects renters by documenting the apartment’s condition when you move in and out, especially if a pet is present, and should be completed at the start and end of your tenancy to avoid disputes over pet-related damages.

Breed and Weight Restrictions in Washington

Landlords can set their own pet terms, and unless local or state law limits them those terms stand — many properties that allow dogs restrict specific breeds and set weight limits, often capped around 25 pounds. These restrictions are usually driven by insurance carrier requirements rather than personal preference, which is why you’ll often see the same handful of breeds excluded across otherwise unrelated buildings.

In Washington specifically, a landlord could argue that a dangerous breed of dog, such as a pit bull or rottweiler, puts their property insurance at risk, and some in the Washington Landlord Association treat this as a valid reason for denying even a service or companion animal. That position is legally contested, since federal fair housing guidance generally calls for an individualized assessment of an animal’s actual behavior rather than a blanket breed exclusion for assistance animals.

Pro Tip: If a landlord cites insurance as the reason for a breed denial, ask for the specific policy language in writing. Many insurers exclude breeds by name in their underwriting guidelines, and seeing the actual clause helps you understand whether the restriction is negotiable.

Weight and breed rules exist for ordinary companion animals, but they stop applying the moment a disability-related accommodation is involved. None of a landlord’s pet rules — breed, weight, or number — ever apply to assistance animals, and landlords cannot deny an emotional support animal by breed, since breed restrictions simply do not apply to ESAs.

If a breed restriction rules out the dog you had in mind, it’s worth considering apartment-friendly alternatives. A rabbit breed suited to small spaces often clears a building’s pet policy without triggering weight limits or insurance riders. If you do bring home a dog, basic care knowledge helps too — knowing how many teeth dogs have can inform decisions about chew toys and flooring protection that keep your deposit intact.

Service Animals and Emotional Support Animals: Your Rights in Washington

Understanding the legal distinction between pets, service animals, and emotional support animals matters, because in Washington State service animals are not considered pets and must be accommodated regardless of a building’s pet policy. That distinction is why a “no pets” sign in the leasing office doesn’t apply to you if you rely on a trained service dog.

Landlords also cannot charge tenants deposits, extra fees, or cleaning charges for service animals, and doing so risks a discrimination complaint according to the Tenants Union of Washington State. The same protection extends to emotional support animals — landlords cannot deny housing to a tenant with an ESA or impose pet fees or deposits, though they can require documentation from a licensed mental health professional to verify the need for the animal.

Enforcement tightened heading into 2026. With House Bill 1217 expanding the Attorney General’s enforcement authority statewide, Washington landlords are expected to treat compliance with assistance animal laws as a non-negotiable requirement, and the same bill, effective May 7, 2025, introduced statewide rent stabilization, capped annual rent increases, required 90-day notice for rent increases, and established lease parity rules alongside the expanded enforcement authority.

If your building’s standard policy would normally exclude your dog’s breed, that restriction doesn’t survive contact with a legitimate assistance animal request. These protections apply even under a city-wide breed restriction — for instance, Auburn restricts pit bulls and kuvasz, but if your emotional support animal happens to be either breed, you won’t be forced to leave the city, and you can legally live with that dog in a rental.

To use these protections, you generally need to make the request yourself. You can request a reasonable accommodation at any point, including after signing a no-pet lease, by submitting your request in writing along with a letter from a licensed mental health professional; your landlord then has up to 30 days to respond, and if they refuse without a legally valid reason, you can file a complaint with HUD. On the flip side, you don’t have to disclose an ESA on a rental application unless you choose to, since privacy laws protect you from being required to do so before a lease is signed.

Can a Landlord Change the Pet Policy Mid-Lease in Washington

A signed lease is a contract, and Washington treats material terms — including pet policies — as fixed for the length of that term. Rent increases, for comparison, only take effect when a lease comes up for renewal, and landlords cannot raise rent in the middle of a lease term, and the same fixed-term logic generally applies to other substantive lease terms your landlord agreed to when you signed.

Under statewide law, a landlord must give tenants proper written notice at least 90 days before the end of the rental period, counted by the notice period rather than calendar days — for example, notice given on or before June 30 would put new terms into effect roughly 90 days later, at the start of the next rental period. A landlord who wants to convert a pet-friendly building to a no-pet building would typically apply that change at your next renewal, not in the middle of your current lease, and give proper advance notice of the new terms.

House Bill 1217’s lease parity rules, which took effect May 7, 2025, reinforce that landlords can’t apply new lease terms unevenly or spring them on tenants without the required notice window. If you’re on a month-to-month agreement rather than a fixed-term lease, your landlord has more flexibility to introduce policy changes with proper notice, but a true no-pet clause still can’t be used to force out a tenant with a legitimate service animal or ESA, regardless of when the new policy takes effect.

Pro Tip: Get any pet policy change in writing, along with its effective date. If a property manager verbally tells you dogs are suddenly banned, ask for the amendment in writing before you consider rehoming a pet you already have permission to keep.

What to Do If Your Landlord Won’t Allow Your Pet in Washington

What you do next depends on whether your animal qualifies for disability-related protections or whether you’re negotiating for an ordinary companion animal.

1. Re-read your lease and any pet addendum. Confirm exactly what’s prohibited and whether the restriction is stated clearly enough to be enforceable.
2. If it’s a service animal or ESA, submit a written accommodation request. Include a letter from a licensed mental health professional and give your landlord up to 30 days to respond.
3. Escalate an unlawful denial to HUD. If your landlord refuses without a legally valid reason, you can file a complaint with HUD.
4. For an ordinary pet, negotiate in writing. Offer a higher pet deposit, provide veterinary and behavior records, or propose a trial period, since consistent documentation strengthens your position.
5. Try mediation before litigation. Mediation is a preferred way to resolve pet-related disputes without going to court, since it’s less costly and time-consuming and can lead to amicable agreements.
6. File in small claims court if mediation fails. Small claims court offers a venue to address pet-related issues when informal resolution doesn’t work.
7. Use official state resources. Washington Law Help provides comprehensive guidance on tenants’ rights, helping renters understand what landlords can and cannot do concerning pets, and the Attorney General’s office publishes sample forms for documenting your unit’s condition.

Sometimes a landlord’s objection isn’t about pets in general but about a specific species they’ve had bad experiences with. If that’s the case, it helps to show you understand which animals are genuinely difficult to manage in an apartment — being able to say your choice isn’t one of the worst animals to keep as apartment pets can go a long way in a conversation with a hesitant property manager.

Responsible ownership also shapes how landlords perceive pet tenants generally. Simple habits — like never leaving pets in hot cars in Washington during summer visits to the leasing office, keeping vaccinations current, and cleaning up after your animal in shared spaces — build the kind of track record that makes landlords more willing to grant exceptions down the road.

If your pet is banned outright and none of the above resolves things, weigh whether a different unit or a more clearly pet-friendly building is worth the move. Low-maintenance pets suited to families and small households tend to clear apartment screening more easily than large or high-energy animals, and choosing accordingly from the start can save you the entire negotiation.

Whether you can have pets in apartments in Washington ultimately comes down to your lease’s specific language, not a single blanket state rule. Read your pet addendum closely, keep every pet-related payment and communication in writing, and remember that assistance animals carry protections no ordinary lease clause can override.
