Detroit Certificate of Appropriateness for Alterations
In Detroit, Michigan property owners in locally designated historic districts must obtain a Certificate of Appropriateness (COA) before making exterior alterations that affect the appearance of a building or site. This guide explains when a COA is required, which department enforces the rules, how to apply, typical timelines, and what to expect at review. It summarizes official Detroit procedures and points you to the primary municipal source for forms and contacts.

The Historic District Commission (HDC) and the City’s historic preservation staff review proposals for compatibility with the district design standards.
