city | Depends on scope | Replacing siding needs no building permit in Seattle. Replacing sheathing, changing structure, or altering doors or windows needs one.

This shall not include structural changes, replacement of sheathing or alteration to doors and windows." A permit is needed when the job changes structure, replaces sheathing, or alters doors or windows.

How this table is built
Each row reflects the most-recently-verified authoritative rule on file for that jurisdiction and project type. “Pending verification” means we have the jurisdiction in our database but haven't yet personally checked the city page for siding rules — those rows fall back to county or WA-state baselines until verified. Sources link directly to the city or county page we read on the verified-on date. See our data-quality leaderboard for how we keep these current.
