What work requires a Certificate of Appropriateness (COA) ?

A COA is required for any proposed changes to building exteriors or sites within a local historic district or a local landmark. Possible proposed changes include new construction and alterations to and restoration of buildings, walls and fences, paving, landscaping, above-ground utilities, lighting, and signage. No COA is required for routine maintenance that results in no change in appearance, design, or materials.
