Historic Preservation

Historic Preservation Planning has long been advocated by Baltimore County plans and policies. Historic districts, buildings and their settings provide continuity with the past, establish a tangible sense of place, enhance the visual quality of life in the County and present opportunities for economic revitalization.

Historic Preservation staff implement the County’s programs and strives to improve preservation information and processes for key stakeholders and the general public to leave a visible legacy for learning and enjoyment by future generations.

Landmarks Preservation Commission

A key stakeholder in the Historic Preservation Program, the Landmarks Preservation Commission (LPC) conducts design reviews for exterior and site alterations to locally-designated historic structures and historic districts, through the historic review or tax credit application processes. The LPC also approves eligible Baltimore County properties for inclusion on the Preliminary Landmarks List and consider petitions for new Baltimore County Historic Districts (BCHD).

Baltimore County Landmarks and Historic Districts

A Baltimore County Landmark or a Baltimore County Historic District (BCHD) is a local historic designation created by the Baltimore County Zoning Code. It recognizes historic properties, sites, buildings, structures, objects, or areas for their significance in Baltimore County and or American history, archaeology, architecture, engineering or culture, and identifies them as worthy of preservation. Learn more about how to submit nominations for Landmarks and Historic Districts.

Historic Tax Credit Programs

Baltimore County and the Maryland Historical Trust (MHT), the state agency for Historic Preservation, both offer historic rehabilitation tax credit programs to residential and commercial properties that qualify. Both programs may be used in conjunction, for projects that return the historic structure “to a state of utility through repair or alteration, that allows for the efficient use of the structure while preserving those portions and features of the structure and its site and environment, that are historically, architecturally or culturally significant."

National Register of Historic Places

The National Register of Historic Places (NRHP) is a program of the U. S. Department of the Interior, National Park Service, and is administered at the State level by the Maryland Historical Trust (MHT), the state agency for historic preservation.The NRHP recognizes districts, buildings, structures, objects and sites for their significance in American history, archeology, architecture, engineering or culture, and identifies them as worthy of preservation.

A NRHP historic designation is largely honorary and does not provide protections at the local level, however, they are reviewed in the planning phases of federally and state funded or permitted projects.

Properties listed on the NRHP or that are contributing resources in a National Register Historic District are eligible for State and Federal tax credits for historic rehabilitation. In addition, a NRHP designation in Baltimore County is eligible for Baltimore County’s historic rehabilitation tax credit program.

Maryland Inventory of Historic Properties

The Maryland Inventory of Historic Properties (MIHP) is a catalog of survey information or documentation on resources of known or potential value to the prehistory and history of the State of Maryland. The MIHP is not a historic designation. Inclusion on the MIHP involves no regulatory restrictions or controls. It is solely an instrument for research and documentation. The information gathered is often used to determine if a property is eligible for designation as a Baltimore County Landmark, BCHDs or for the National Register of Historic Places. This is why County Landmarks, BCHDs and National Register listings have MIHP inventory numbers.

The MHIP contains information about both standing structures and archeological resources. The survey information gathered on inventoried properties contribute to our understanding of Maryland’s architecture, engineering, archaeology or culture. Search the Maryland Inventory using MHT’s online database, MEDUSA.
