When does Seattle Landmarks Preservation Board review apply?

Answered by AskBaily Editorial · Updated

Short answer

Landmarks review applies in Seattle's designated historic districts — Pioneer Square, Pike Place Market, Ballard Avenue, Columbia City, Harvard-Belmont, and the International District — plus ~450 individually landmarked buildings. Any visible exterior alteration inside these overlays requires a Certificate of Approval before SDCI issues the permit. Plan 6-16 additional weeks for staff-level CofA review; Board-level review extends to 20-32 weeks.
