Contact the Department of Neighborhoods early to confirm whether your property requires a Certificate of Appropriateness.

Overview

A Certificate of Appropriateness (sometimes called a Certificate of Approval in city literature) is the formal decision that proposed exterior work on a landmark or within a historic district is compatible with the district or landmark designation. The certificate applies to changes such as material replacement, additions, demolition, signage, and site work when review is required by the landmark ordinance or district rules.

When you need one

  • Work on a designated landmark or within a local historic district.
  • Exterior alterations, additions, demolition, or new construction that affect the landmark or district character.
  • Projects that trigger design review under the applicable preservation board rules.

Penalties & Enforcement

Enforcement for failure to obtain a required Certificate before starting regulated work is handled through city administrative processes and may involve permit holds, stop-work orders, or enforcement action by the Department of Neighborhoods in coordination with permitting agencies.

  • Monetary fines: not specified on the cited page.
  • Escalation: first, repeat, or continuing offense penalties are not specified on the cited page.
  • Non-monetary sanctions: stop-work orders, required restoration, permit denial or conditioned permits are used as enforcement tools.
  • Enforcer and complaint pathway: the Department of Neighborhoods Historic Preservation handles preservation review and referral; complaints and inspections are coordinated with Seattle Department of Construction and Inspections (SDCI).
  • Appeals and review: appeal routes exist through the city review process; specific appeal time limits are not specified on the cited page.
