Who to ask about permits in SeaTac
Permit questions go to the City of SeaTac's Permit Center, at 206-973-4750 or permitcenter@seatacwa.gov. Its checklists cover decks, drainage control, new homes, additions, remodels and re-roofs. Driveways and patios aren't named on that list, so we don't guess. Before we schedule, we check which office covers your address, and when the job needs a permit, we handle the application and plan the start date around the wait.
You can check two things about any contractor before you sign. Washington requires every construction contractor to register with the state Department of Labor & Industries, and state law also requires them to be bonded and insured. SeaTac also requires a city business license from businesses that work in the city from somewhere else, not just ones based inside city limits. Ask a contractor for both.
- If your job needs a permit, it sets the start date.
- Every Washington construction contractor must register with L&I.
- SeaTac's business license applies to contractors based outside the city too.
