Seattle's rules for kitchen remodels
- SDCI says you don't need a permit for minor repairs or alterations that cost $6,000 or less in any 6-month period, counting labor and parts at fair market value, even if you do the work yourself.
- SDCI lists installing kitchen cabinets among projects that usually don't need a permit.
- You need a permit for any work on load-bearing supports, changes to the building envelope (a new window or exterior door, for example), or work that reduces egress, light, ventilation or fire resistance, "no matter how small the project."
- Electrical, plumbing and gas work need their own trade permits, whatever the project's size.

Who issues each permit in Seattle
| Permit | Issued by | Good to know |
|---|---|---|
| Building (walls, windows, structure) | SDCI | Non-structural interior alterations in single-family homes typically qualify for a Subject-to-Field-Inspection (STFI) permit, which SDCI typically processes within one working day. You file a checklist, a location plan and a floor plan. |
| Electrical | SDCI | Owners may do their own electrical work only in a home they own and live in. Most electrical permits need cover, service and final inspections. |
| Plumbing and gas piping | Public Health – Seattle & King County | Homeowner permits are available. Installing or changing gas piping needs a separate gas piping permit. |
SDCI's STFI option also covers some structural openings in single-family homes, such as a new opening in a load-bearing wall that supports one story and the roof, with a beam span of up to 14 feet. Larger structural changes need full plan review.

Seattle doesn't charge a flat permit fee: SDCI says its fees depend on what you install or alter, and Angi's Seattle page says they are based on the value of labor and materials. For 2026, SDCI says its construction permit fees rose 18% and its base hourly rate is $292. Ask each contractor whether permit fees are included in the quote.
How long a kitchen permit takes
- Seattle STFI permits: SDCI says it typically processes them within one working day of filing. Work can't start until the permit is issued.
- Angi says electrical and plumbing permits can sometimes be issued immediately, while building permits for structural changes typically take four to six weeks.
- Inspections happen during the job, so plan for the inspector's visits in the schedule.
What happens if you skip the permit
Angi warns that unpermitted work can invalidate insurance coverage, cause problems when you sell or refinance, bring fines and fees for applying after the fact, and force structural work to be redone to code.
Before you start
- Ask who pulls each permit (building, electrical, plumbing, gas) and whether the fees are in the quote.
- Look the contractor up on L&I's Verify a Contractor tool: active license, bond, insurance and past violations.
- For jobs of $1,000 or more on a home, the contractor must give you a written disclosure statement before work starts (RCW 18.27.114).
- Not sure whether your project needs a permit? Call SDCI at (206) 684-8600 before work starts.
