Do I need a permit to replace a bathtub in Washington?

A true like-for-like swap — new tub, same location, existing plumbing connections — often needs no permit. But most tub replacements today are really tub-to-shower conversions or involve a new valve in the wall cavity, and those require a plumbing permit in nearly every Washington jurisdiction.

Can I remodel a kitchen without a permit?

Yes, if the layout stays put: new cabinets, countertops, flooring, paint, and appliances in the same locations generally need no permit. Moving the sink, adding an island with power or plumbing, relocating outlets, adding circuits, or removing a wall all trigger permits.

Who pulls the permit — the homeowner or the contractor?

Either can, but on professionally built projects the contractor normally pulls the permits and is the point of contact for inspections. Be cautious if a contractor asks you to pull an owner's permit for work they are performing — it shifts responsibility to you and is a recognized warning sign.

How long do remodel permits take in the Seattle area?

Simple trade permits (plumbing, electrical) are often same-day to a couple of weeks. Building permits for interior remodels commonly take a few weeks; additions and ADUs typically run 6–12 weeks or more depending on the jurisdiction and the completeness of the submittal.

Does unpermitted remodeling affect selling a house in Washington?

Yes. Washington's seller disclosure statement asks whether work was done without required permits, buyers and lenders can demand retroactive permits or price the risk into their offer, and insurers can contest claims tied to uninspected work.

Do You Need a Permit to Remodel a Bathroom or Kitchen in Washington?

The short answer

In Washington, cosmetic, like-for-like work generally does not need a permit: paint, flooring, cabinets and countertops in the same layout, or swapping a faucet, toilet, or vanity in the same spot on existing lines. Anything that moves or adds plumbing, wiring, or walls generally does: relocating a sink or shower, adding circuits or outlets, removing walls, changing windows or exterior openings, or converting or adding square footage. Permitting in Washington is administered city by city, so the details — fees, forms, review times — depend on where the house sits, but that dividing line holds almost everywhere we build.

What usually needs no permit

Painting, trim, and interior finishes
Flooring replacement
New cabinets and countertops in the existing layout
Like-for-like fixture swaps — faucet, toilet, vanity, or appliance on existing connections
Minor repairs below your city’s exemption threshold

One caveat worth taking seriously: “replacing” has a narrow meaning. The moment a tub swap becomes a new shower valve in the wall cavity, or a vanity swap adds an outlet, you have crossed into permit territory.

What always needs a permit

Moving, adding, or upsizing plumbing — drains, supply lines, or fixtures in new locations
New electrical circuits, relocated outlets, or panel work
Removing or opening walls — especially load-bearing walls, which also need engineering
Changes to windows, doors, egress, or the building envelope
Additions, attic and basement conversions, and ADUs
Water heater, furnace, and ductwork replacement (mechanical/plumbing permits)

How it differs around Puget Sound

Each jurisdiction runs its own counter. Seattle (SDCI) offers streamlined subject-to-field-inspection permits for straightforward interior remodels, alongside separate plumbing and electrical permits. Snohomish County handles unincorporated areas through Planning & Development Services, while cities like Lynnwood, Edmonds, Bothell, and Everett issue their own — we cover Lynnwood’s specifics in our Lynnwood permit guide. In our experience, trade permits for a typical bathroom or kitchen remodel run from a few hundred dollars each, with building permits scaling on project valuation — real money, but a rounding error next to what unpermitted work can cost you later.

Why skipping permits backfires

Unpermitted work surfaces at the worst times: when you sell (Washington’s seller-disclosure form asks directly), when you refinance or the appraiser notices, when an insurance claim touches work no inspector ever saw, or when a neighbor’s complaint triggers a stop-work order. Retroactive permitting usually means opening finished walls for inspection — paying twice for the same drywall. Permits are cheap insurance, and inspections are a second set of trained eyes on your house.

Who handles the paperwork

On our projects: we do. Go Far Construction prices permits into the itemized estimate, prepares the drawings and submittals, pulls the permits, and meets the inspectors. The permit is filed with the city either way — what you are choosing is whether managing it is your job or ours. If you are planning a project and are not sure which side of the line it lands on, ask us — it is a two-minute answer.
