Certificate of Appropriateness

Acquiring the appropriate permits for the proposed project, in some instances, is not the only requirement of the Columbus City Code. There are multiple historic districts and commission areas in our city that require a review of the proposed design prior to obtaining the permits to begin construction.

Please refer to theOnline Zoning Mapto verify if your project is located in one of these areas. A Certificate of Appropriateness will be required from the historic district or commission area for all projects located there.
