A Certificate of Appropriateness (COA) assures that your historic property maintains its historic integrity and that structures within the Historic Overlay District respect the historic character of the area.
A COA serves a two-fold purpose for historic properties. First, it helps ensure that the proposed work maintains the property's historic integrity and will evaluate the proposed work’s impact on the historic building. The qualities that make your property either architecturally or historically notable can only be maintained or enhanced when alterations are made according to universally accepted historic preservation practices. Second, it helps ensure that all structures within the “H” Overlay District respect the historic character of the area. That means that even brand-new construction needs a COA to ensure compatibility with the historic neighborhoods.
