The Maryland Inventory of Historic Properties (MIHP) is a broad-based collection or catalog of survey information on districts, sites, buildings, structures, and objects of known or potential value to the history of the United States, Maryland, and Harford County.
The inventory is maintained by the Maryland Historical Trust (MHT), the state agency for historic preservation, and is solely used for educational and research purposes. Inclusion in the MIHP involves no regulatory restrictions or controls and is different from a formal historic designation. It can be used as the first step in determining eligibility for the National Register and/or local landmark designations.
Harford County has more than 2,500 recorded resources on the MIHP. The MIHP for Harford County functions as the county’s inventory of historic resources. The Department of Planning and Zoning and the Historic Preservation Commission maintain and update the inventory and use it as a tool for county planning. MIHP information is available online and kept on file for public viewing at the Department of Planning and Zoning offices and in duplicate at the Maryland Historical Trust Library in Crownsville, MD.
