Historic District Review Committee
General Purpose
The Historic District Review Committee (HDRC) is a seven-member review committee appointed by the Board of Supervisors and charged with maintaining the architectural and historic integrity of Loudoun County's Historic Districts.

The HDRC uses the county’s Historic District Guidelines as the basis for review of proposed projects. The Historic District Guidelines are an adopted part of the county's Zoning Ordinance, and relate only to the exterior appearance and the siting of structures on a property.

The siting of new construction is particularly important in a rural district where the protection of historic landscapes and viewsheds is of special importance. The guidelines are available to the public as a guide for the renovation of existing structures and/or new construction projects.

The HDRC publishes a twice yearly newsletter “What’s Old is News” with insights and helpful information for owners of historic properties. The newsletters are mailed to residents in the county’s historic districts and are also available online (Adobe Reader required).


Committee members are appointed at large by the Board of Supervisors and serve three-year staggered terms. For more information on the application process, please click here.
