What is a Certificate of Appropriateness?

A Certificate of Appropriateness (COA) is a document approving work on local historic landmarks or properties in local historic districts based on consistency with the applicable review criteria. When changes are proposed to properties within local districts or to landmarks, the proposed changes are reviewed against the Local Historic Properties Review Criteria. If the proposed changes are consistent with the Criteria, either staff or the Historic Preservation Commission will issue the COA. A COA is required prior to the issuance of a building permit and is required even if no other permit is needed for the work proposed. If an applicant wishes to appeal a COA decision, he or she must appeal to the Board of Adjustment (BOA); a BOA decision may be appealed to the county Superior Court.
