Our Mission

The mission of the Maryland Association of Historic District Commissions (MAHDC) is to provide advocacy, training and program support for historic preservation commissions and local governments across the state. Formed in 1979, MAHDC serves 47 commissions, representing both urban and local historic districts, local governments, commissioners, residents and owners of historic properties. Our basic philosophy is that by working together, Maryland’s historic district commissions can help one another become more effective protectors of the historic resources in each of their own communities.
