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.
In detail
Landmarks review attaches whenever a property sits inside one of Seattle's seven designated historic districts or is on the individually landmarked list of roughly 450 buildings, sites, and objects. The seven districts are Pioneer Square Preservation District, Pike Place Market Historical District, Ballard Avenue Landmark District, Columbia City Landmark District, Harvard-Belmont Landmark District, Fort Lawton Landmark District, and the International Special Review District. The legal authority is SMC Chapter 25.12 (Landmarks Preservation Ordinance) and the parallel district-specific chapters at SMC 25.16 through 25.30.
Any exterior alteration visible from a public right-of-way (window replacement, paint color in some districts, signage, awnings, roof material, additions, demolitions, fenestration changes) requires a Certificate of Approval issued by the Landmarks Preservation Board or, for in-kind work, by board staff under delegated authority. SDCI will not issue a building, mechanical, or electrical permit on a landmarked property until the Certificate of Approval is in hand.
Review pace splits cleanly. Staff-level Type I review (in-kind repair, paint, minor signage) typically resolves in 2 to 6 weeks. Type II staff review (most window swaps, smaller roof work, mechanical screening) lands in 6 to 16 weeks. Full Landmarks Board review for new additions, demolitions, or contemporary infill stretches to 20 to 32 weeks because the Board meets twice monthly and most projects need at least one briefing and one action meeting, sometimes preceded by an Architectural Review Committee work session.
The judgment-call that drives schedule risk: the Boards apply the Secretary of the Interior's Standards for Rehabilitation, and material substitution is the most common point of friction. Fiber-cement substitutes for original cedar, vinyl-clad windows for old-growth fir, or composite shingles for slate are routinely sent back for revision in the contributing-structure review of districts like Harvard-Belmont and Pioneer Square. Front-loading a materials submittal at the pre-application phase consistently saves 6 to 10 weeks versus discovering the issue at the formal Type II hearing.
