Certificate of Appropriateness (COA)


COACertificate of Appropriateness (COA) is required for all work that would change the exterior appearance of a designated historic property. A COA includes the categories of alterations (additions), new construction and demolition, and relocation.

The COA is the application that the Historic Preservation Board (HPB) reviews at their monthly meetings. During their reviews, the HPB references the criteria set forth in the historic preservation sections of the City’s Unified Land Development Regulations. Review by the HPB insures that any proposed changes will be compatible with the character and design of the individual property and/or historic district.

The process of applying for a COA requires the owner to provide sufficient information on the City’s application form and to provide a narrative, drawings, sketches, photographs, a survey, proof of ownership, and possibly product approvals or brochures for certain building features that will be modified. The owner or representative will consult with staff to ensure that all the information is included in the application. The applicant or his agent must be present at the HPB meeting to answer any questions the HPB may have regarding the application.
