Changes to landmark properties
Significant historic and archaeological properties in unincorporated King County including buildings, sites, districts, objects, and structures are protected by certain design review processes and may be eligible for certain incentives.
Any major restoration or changes of a significant feature of a designated King County Landmark property in unincorporated King County requires a Certificate of Appropriateness (COA), which is granted through a design review process. "Landmark" refers to a physical property that has been formally designated and listed on a register of historic places by an agency of government.The COA process is separate from the building permit process. COAs must be obtained through the King County Historic Preservation Program before building permits are issued. Some projects that do not require building permits may still require COAs. Design review may result in changes to the project specifications; the Historic Preservation Program recommends applying for a COA prior to finalizing your plans.
