A practical permit path

1
Confirm which permitting office serves the property

A Seattle mailing address can be outside incorporated Seattle. Shoreline, environmentally critical area, landmark, tree and utility layers can add separate decisions.

2
Define the complete project scope

Document the equipment, location, connections and any related structural, electrical, plumbing, fuel or fire work.

3
Verify the application and permit holder

Ask Seattle Department of Construction and Inspections which permit type applies and whether the homeowner or a locally qualified contractor must apply.

4
Complete inspections and close the permit

Permitted remodels can need rough plumbing, electrical, framing or mechanical inspections before walls close, followed by finals.

Conditions that change the answer

Cosmetic or layout change

Paint, finishes and unchanged fixtures are different from moving walls, drains, supplies or doors.

Wet-area work

Shower pans, waterproofing, ventilation and safety glazing can add inspection checkpoints.

Electrical scope

New circuits, lighting, receptacles and exhaust fans can create an electrical permit.

Inspection and close-out

Permitted remodels can need rough plumbing, electrical, framing or mechanical inspections before walls close, followed by finals. Keep the approved documents, inspection results and final permit record with the property files.

Do not treat the mailing city or a contractor estimate as proof of jurisdiction. Check the property in the official city or county system before relying on this guide.
