Seattle Roofing Permit Requirements

Seattle requires permits for most roofing work including full replacements, overlays, and structural repairs. The Seattle Department of Construction and Inspections (SDCI) handles all building permits. Seattle has its own online permit portal (Seattle Services Portal) and is one of the higher-volume permit offices in the region.

Some neighborhoods have landmark or historic district requirements — confirm before starting any project.
