If you’re planning a kitchen remodel in Seattle or anywhere in King County, the permit question comes up fast. The short answer: a kitchen remodel permit is required for most real remodels — anything that touches plumbing, electrical, walls, or ventilation. Purely cosmetic work usually doesn’t need one.
I’m a general contractor here in Seattle, and permits are part of almost every kitchen we build. Here’s how it actually works in 2026 — what needs a permit, what doesn’t, what it costs, and how long it takes.
Typical kitchen permit costs in Seattle (2026 estimates)
| Permit | Typical cost (estimate) |
|---|---|
| Building permit (same-footprint remodel, ~$65K project) | ~$830 |
| Plumbing permit | ~$300 |
| Electrical permit | ~$380 |
| Total, typical full kitchen remodel | ~$1,500–$2,100+ |
These are estimates based on 2026 SDCI fee schedules. Fees scale with project valuation, and each city sets its own rates.
Do You Need a Permit to Remodel a Kitchen?
It depends on what you’re changing, not how much you’re spending.
You need a permit when the project involves:
- Moving or adding plumbing — relocating the sink, adding an island with a prep sink, moving the dishwasher drain
- Electrical work — new circuits, moving outlets, adding recessed lighting, upgrading the panel for an induction range
- Removing or altering walls — even a partial wall or a pass-through opening
- New or relocated venting — range hood ducting through a wall or roof
- Moving gas lines for a range or cooktop
You usually don’t need a permit for:
- Painting
- New countertops
- Replacing cabinets in the same layout
- New flooring
- Swapping appliances in the same spot (plug-in, no new circuits or gas work)
Seattle also exempts some minor interior work under about $6,000 in value — but that exemption disappears the moment plumbing, electrical, or structure is involved. In practice, almost every full kitchen remodel needs at least one permit, because the sink, the wiring, or the layout is changing.
One Seattle-specific detail that surprises homeowners: many older homes here have 1.5-inch kitchen drain lines, and current code calls for 2-inch. If your remodel touches the sink drain, the upgrade usually comes with it — and that’s a plumbing permit.
Kitchen Remodel Permit Cost in 2026
Permit fees are based on project valuation, so bigger projects pay more. Based on the 2026 Seattle fee schedules, a same-footprint full kitchen remodel valued around $65,000 runs roughly $830 for the building permit, $300 for plumbing, and $380 for electrical — call it $1,500 all-in. Take out a wall and push the valuation to $90,000, and you’re closer to $1,700–$2,100 total.
All of these are estimates. Every city in King County sets its own fee schedule, and fees change yearly. The permit line on your budget is real, but it’s small next to the project itself — see our full breakdown of kitchen remodel costs in Seattle.
Who Issues the Permit Depends on Where You Live
King County isn’t one permit office. Where your house sits decides who you deal with:
Seattle. The Seattle Department of Construction and Inspections (SDCI) issues the construction permit. Most same-footprint kitchen remodels qualify for a subject-to-field-inspection (STFI) permit — a simpler, faster version with less paperwork, where the inspector checks the work in the field instead of a full plan review. Electrical permits also go through SDCI (Seattle runs its own electrical program). Plumbing is the odd one out: plumbing and gas piping permits in Seattle come from Public Health — Seattle & King County, a separate agency.
Bellevue. Permits go through MyBuildingPermit.com, the regional portal Bellevue shares with several Eastside cities. Non-structural remodels that don’t change the building footprint can often be issued the same day under the no-plan-review remodel permit.
Renton. Renton runs its own permit counter through the city’s Development Services division, with its own fees and review times.
Unincorporated King County. If you’re outside city limits — parts of the Eastside, rural King County — the King County Permitting Division handles the building permit, and Public Health handles plumbing and gas, same as Seattle.
If you’re not sure which jurisdiction you’re in, look up your address on the King County parcel viewer, or just ask us — it’s the first thing we check on any project.
How Long Does a Kitchen Permit Take?
In Seattle, an STFI permit for a straightforward kitchen remodel is usually the fast path — often days to a couple of weeks. A full plan review takes longer; SDCI reviews typically run at least four weeks, sometimes more in busy seasons. We covered the details in our post on Seattle DCI permit approval timelines.
Bellevue’s no-plan-review permits can be same-day. Renton and unincorporated King County vary by workload — plan on a few weeks for anything with structural changes.
The practical takeaway: permits belong at the start of your schedule, not the end. We file them while cabinets are on order, so the paperwork and the lead times run in parallel instead of stacking up.
What If You Skip the Permit?
Tempting, and a bad idea. Unpermitted work in Seattle is a civil infraction — and it tends to surface at the worst time, like when you sell the house and the buyer’s inspector starts asking questions. You can end up paying for permits after the fact, opening up finished walls for inspection, or redoing work entirely. We wrote about exactly what happens if you remodel without a permit in Seattle.
A licensed contractor should never ask you to skip permits. If one does, that tells you something.

Frequently Asked Questions
Do I need a permit to replace kitchen cabinets?
Not if the new cabinets go in the same layout with no plumbing or electrical changes. Move the sink run or add circuits for under-cabinet lighting, and a permit comes into play.
Do I need a permit for new countertops or flooring?
No. Countertops, flooring, paint, and backsplash are cosmetic — no permit needed anywhere in King County.
Can I pull a kitchen permit myself as a homeowner?
Yes, if you own and occupy the home you can apply as an owner-builder. But if a contractor is doing the work, the permit should generally be in the contractor’s name — that keeps responsibility for code compliance where it belongs.
How much does a kitchen remodel permit cost in Seattle?
For a typical full kitchen remodel, plan on roughly $1,500–$2,100 total across building, plumbing, and electrical permits (2026 estimates — fees scale with project value).
Does moving the kitchen sink require a permit?
Yes. Relocating the sink means new drain and supply lines, which requires a plumbing permit — in Seattle that comes from Public Health — Seattle & King County, not SDCI.
