Frederick County, VA Building Setbacks & Zoning: Lot Coverage Limits (2026)

60, meaning no more than 60% of the site can be covered by buildings, pavement and other surfaces that keep water from soaking into the ground. That cap sits alongside the district's setback and height rules for the same uses under the same table: garden apartments and multifamily buildings hold a 35 to 60 foot principal-structure front setback and can reach 55 to 60 feet in height, while age-restricted multifamily housing runs larger setbacks (60 feet front, 100 feet side and rear) tied to a lower 40-foot height limit that the Board of Supervisors can waive up to 60 feet if adjacent residential uses will not be harmed. 60 ceiling is specific to the district's multifamily housing types rather than a countywide lot-coverage rule. 60 ratio before approval.
