Seattle has some of the strongest deposit rules in the country. On top of Washington’s 30 day refund deadline and move in checklist requirement, the city caps the deposit and fees combined at one month’s rent and lets renters pay in installments. In the city of Seattle, about 204,500 of 363,500 occupied homes, or 56.3 percent, are rented, according to the U.S. Census Bureau’s 2020 to 2024 American Community Survey (Homzora Seattle dataset, Table B25003). The median gross rent is $2,030 a month (Homzora Seattle dataset, Table B25064).

Quick answers
- Seattle cap: security deposit and fees combined cannot exceed one month’s rent (Renting in Seattle, Move in costs).
- Checklist: no deposit may be collected without a written lease and a signed move in condition checklist (RCW 59.18.260).
- Deadline: 30 days after the lease ends and you move out (RCW 59.18.280).
- Penalty: up to two times the deposit for intentional refusal to return it (RCW 59.18.280).
How much a Seattle landlord can charge
In Seattle, the security deposit and fees combined cannot exceed one month’s rent. Nonrefundable fees are allowed only for cleaning and screening, capped at 10 percent of one month’s rent, and a pet deposit of up to 25 percent of one month’s rent may be charged on top of the cap (Renting in Seattle, Move in costs). At Seattle’s median gross rent of $2,030, the general cap is $2,030.
Statewide, a fee or deposit to hold a unit cannot exceed 25 percent of the first month’s rent (RCW 59.18.610).
Paying in installments
Washington lets tenants ask in writing to pay deposits, nonrefundable fees, and last month’s rent in installments, with no fees or interest (RCW 59.18.610). Seattle goes further: for a tenancy of six months or more, deposits may be paid in six monthly installments and fees in three, and for a month to month tenancy, deposits in two installments and fees in three (Renting in Seattle, Installment payments).
The checklist and the trust account
A landlord may not collect a deposit without a written rental agreement and a written checklist describing the unit’s condition, signed and dated by both parties, with a copy for the tenant. A landlord who collects a deposit without the checklist is liable for the deposit amount, plus costs and attorney fees (RCW 59.18.260). The deposit must be placed in a trust account at a Washington financial institution or licensed escrow agent, and the tenant must be told where (RCW 59.18.270).
The 30 day rule
Within 30 days after the lease ends and you move out, the landlord must return the deposit or give a full and specific statement of the basis for keeping any of it. Damage charges must include copies of estimates or paid invoices, and repairs the landlord does personally must show time spent and the hourly rate (RCW 59.18.280). Seattle notes that a landlord who needs more time for repair quotes or a final utility bill must notify the tenant within the 30 days (Renting in Seattle, Return of your security deposit).
What cannot be deducted
A landlord may not charge for ordinary wear and tear, for carpet cleaning unless wear beyond ordinary use is documented, for items not recorded on the move in checklist, or for replacing more than the damaged portion (RCW 59.18.280).
Penalties
A landlord who misses the deadline is liable for the full deposit and generally loses later claims against it, with limited exceptions. If a landlord intentionally refuses to return the deposit, a court may award up to two times the deposit, and the prevailing party recovers costs and attorney fees (RCW 59.18.280).
Nonrefundable fees
A nonrefundable fee cannot be called a deposit, and the written agreement must clearly say it is nonrefundable; otherwise it is treated as a refundable deposit (RCW 59.18.285).
A worked example
Suppose your rent is $2,030. Your landlord may charge a deposit and fees totaling no more than $2,030, plus a pet deposit of up to $507.50 (Renting in Seattle, Move in costs). You move out June 30. By July 30, the landlord must return the deposit or send a full statement with invoices (RCW 59.18.280). A charge for scratches that appear on your signed move in checklist is not allowed (RCW 59.18.280).

Build your evidence file
Landlord and tenant disputes are usually decided by documents. Keep these together from the day you sign:
- The signed lease, every addendum, and every renewal.
- Receipts or bank records for the deposit and each rent payment.
- Dated photos and video of every room at move in and move out.
- Copies of every repair request and the landlord’s replies.
- Every notice you send or receive, with proof of delivery.
Keep copies somewhere other than your phone, such as an email to yourself, so they survive a lost device.
Before you sign your next lease
- Ask who owns and who manages the property, and get contact details in writing.
- Read the clauses on early termination, subletting, renewal, late fees, and notice before you sign.
- Confirm the deposit amount, where it will be held, and how it will be returned.
- Walk through the unit, note existing damage in writing, and keep a signed copy.
- Ask how much notice the landlord gives before a rent increase or a non renewal.

Questions to ask at move in
- Where will my deposit be held, and will I receive that information in writing?
- Is there a move in condition checklist, and can I add items to it?
- What cleaning standard does the lease require at move out?
- How and where will the refund be sent?
- Who should I contact about the deposit if the building is sold?
Ask these before you pay. Answers in writing are far more useful than a conversation in the leasing office.
Mistakes to avoid
- Skipping move in photos. Photos are usually the deciding evidence on what damage existed before you.
- Leaving without a final walkthrough. Attend any inspection offered, or ask for one.
- Not giving a forwarding address in writing. It is the simplest way to make sure the refund reaches you.
- Letting deadlines pass. Send a written demand promptly once the refund deadline has passed.
How to document the unit
- Take a slow video of each room, narrating what you see, on move in day and move out day.
- Photograph appliances inside and out, including the oven, refrigerator, and dishwasher.
- Photograph floors in good light, close enough to show scratches or stains.
- Photograph windows, blinds, doors, and closet interiors.
- Email the files to yourself so the timestamps are preserved in your inbox.
