Move-out cleaning in Seattle: what Washington’s deposit rules mean

In Washington, the deposit is settled on paper. A landlord can’t collect one without a written rental agreement and a move-in checklist you both signed and dated, can’t keep any of it for ordinary wear, and has 30 days to refund it or explain, fully and specifically, what was kept. The clean is the part you control.

This is a cleaning company reading chapter 59.18 RCW, Washington’s Residential Landlord-Tenant Act, and Seattle’s move-in rules, with sections cited so you can check them. It’s general information, not legal advice: a deposit already in dispute belongs with a tenant-rights organization or an attorney.

The checklist you signed is the grading sheet

Washington ties the deposit to a document. Under RCW 59.18.260, no deposit may be collected unless the rental agreement is in writing and the landlord gives you, at move-in, a checklist “specifically describing the condition and cleanliness of or existing damages to” the unit. You both sign and date it, and you keep a copy. A landlord who takes a deposit without one is “liable to the tenant for the amount of the deposit.”

Read that phrase the way a cleaner would: condition and cleanliness. At move-out, RCW 59.18.130(10) asks you to “restore the premises to their initial condition except for wear resulting from ordinary use of the premises,” and the checklist is the record of that initial condition. If it says the oven was clean, the oven goes back clean; a stained tub noted on day one is part of the starting line too.

So a move-out starts with paperwork. Find your copy; if it’s gone, the same section gives you the right to request one free replacement copy, so ask in writing now. Then walk the unit with it and mark where the clean has to go deep.

What can come out for cleaning, and the carpet rule

Your written lease has to say when any of the deposit can be kept (RCW 59.18.260 again). RCW 59.18.280 sets the limits:

• Not for wear. “No portion of any deposit may be withheld” for wear resulting from ordinary use of the premises.
• Not for carpet cleaning without proof. Nothing may be withheld for carpet cleaning “unless the landlord documents wear to the carpet that is beyond wear resulting from ordinary use of the premises.”
• Not without paper. The statement must include “copies of estimates received or invoices paid to reasonably substantiate damage charges.”
• Not after 30 days. Within 30 days after the agreement ends and you’ve moved out, the landlord owes you “a full and specific statement of the basis for retaining any of the deposit,” plus any refund. Miss it and the landlord is liable for the full deposit; an intentional refusal can cost the landlord up to two times the deposit in court, with exceptions the statute lists.

The carpet line changes what you buy: in Washington, carpet cleaning comes out of a deposit only against documented wear beyond ordinary use. Extraction isn’t our trade, and our Seattle move-out page says so in one line: “No. Carpet extraction is a separate trade with separate equipment; we vacuum thoroughly and will tell you plainly if a carpet needs more than that before an inspection.” If you need a carpet company too, the order of the two visits is in our post on whether move-out cleaning includes carpet cleaning, written for our Florida market; its legal notes are Florida’s.

Inside Seattle city limits, and across the line

Inside the city, chapter 7.24 of the Seattle Municipal Code regulates deposits and move-in fees, and the City’s Renting in Seattle guidance states the limits: “Security deposit and fees combined cannot exceed one month's rent,” and “Non-refundable fees can only be charged for cleaning and screening and cannot exceed 10% of one month's rent.”

The same page adds a line that matters on move-out day: “A landlord cannot charge you for cleaning at the end of your rental agreement if they charge for cleaning at the start.” State law points the same way across Washington: under RCW 59.18.130(10), a tenant who paid a nonrefundable cleaning fee “shall not be charged for normal cleaning.” Check your lease and move-in receipt for that fee before you book anyone, us included.

Those caps are Seattle’s alone. Bellevue, Kirkland, Redmond, Edmonds and Lynnwood are separate cities, so chapter 7.24 doesn’t reach a lease there; the state act is the baseline, and your city may have rules of its own. Inside Seattle, the Department of Construction and Inspections enforces the City’s landlord-tenant laws and hosts the Renting in Seattle help line.

What October through March does to a move-out

Move out between October and March and the inspector sees a unit in the thick of the wet season. Our Queen Anne page puts the older housing there plainly: “Raised long before air conditioning, that stock holds damp in baths and on north-facing sills through an October-to-March wet season, and the west-facing view glass over Elliott Bay shows every streak in the nine hours of daylight January allows.” NOAA’s 1991–2020 normals for Seattle-Tacoma International Airport agree: the six wettest months run October through March, led by November.

At the walkthrough that means dark spots on bath caulk and grout, mildew on north-facing sills, grit at the entry and streaky glass.

Washington’s Department of Health draws the line to know first: “Generally, fixing leaks is the landlord's responsibility and reducing condensation is the renter's responsibility.” RCW 59.18.060 also has landlords give new tenants the department’s mold information at signing. Surface mildew on a sill is cleaning. A stain that keeps returning from a leak is a repair to report in writing, not something to scrub away the night before the inspection.

Empty, clean, photograph, then the keys

All of it runs on documents, so the order of the last day matters more than its intensity: last box out, then the clean, then dated photos of the empty unit with cabinet doors open, then the walkthrough and the keys. Photos with boxes in the frame prove less than photos of bare floor. Why empty comes first is laid out in our post on emptying the home before a move-out clean, written around our Miami-Dade buildings; the sequence holds anywhere. Book around the one date that won’t move, the key return, and if your building reserves its elevator, fit the clean inside that window.

What our clean covers, and what it can’t promise

Our Seattle move-out page scopes the visit the way this post reads the law: “A move-out clean is graded by someone else, so it is scoped against what that person inspects — not against how the room looks from the doorway.” Its list:

• Cabinets and drawers cleaned inside and out
• Inside the oven and inside the refrigerator
• Closets, shelving and closet tracks
• Baseboards, door frames and switch plates
• Bathrooms detailed: grout, fixtures, exhaust vents
• Floors cleaned edge to edge, including corners
• Interior windows, sills and tracks on request
• Photo record of the finished unit, emailed as a PDF

In a wet-season move-out, “on request” is the line to request. On timing, the page is blunt: “Move-out dates cluster at the end of the month, so the last three days of a month book out first. Tell us your key-return date as soon as you have it, even if the time is not settled yet.”

No clean can promise your deposit. Asked whether we guarantee you’ll get it back, the page answers “No, and nobody honestly can,” then: “What we can do is the cleaning standard a walkthrough is graded on, and hand you dated photo proof of the state we left it in.” Its proof line adds that “eligible completed visits include a CleanCheck report with customer-safe photo proof.” Nothing on that list patches a wall, repaints a room, fixes a leak or remediates the mold it feeds; a deposit statement treats those as other bills, as we argue in our post on cleaning deductions from a deposit, written for the Miami-Dade market under Florida law.
