Within Local Historic Districts and Conservation Districts, a Certificate of Appropriateness (COA) is required for a variety of exterior changes to both contributing and non-contributing buildings when visible from the public right-of-way. Each district has unique regulations and requirements as well as its own COA application and checklists.
Apply for a COA using the application for your local historic district. See Local Historic Districts, Conservation Districts, and Historic Properties to determine in which district you are located.
The applications and checklists can be downloaded from the Applications, Instructions, and Forms section of our website, or hard copies can be obtained in the lobby of the MPC office at 110 East State Street. Submit your completed application, required supplemental information, and filing fee check (when required) to the MPC Office.
NOTICE: Per House Bill 493, detailed checklists of items are now required to be submitted with each development application. Additionally, there is now an affidavit at the end of the application and each checklist that must be signed, certifying that all required items are provided. This new process was adopted to help the review process for all types of development reviews in the state - for both the applicant and the reviewing body.
