Zoning

B-1

ROD

General Business District

The B-1 District is intended to implement the regional commercial center and general commercial land use classifications of the Comprehensive Plan. It is generally intended to provide areas for community-scale retail, office, and institutional uses in appropriate areas. The purpose of this district is to also promote retail employment opportunities and to enhance the tax base of Prince William County. The B-1 District is not designed to implement the non-retail employment based land uses reflected in the Comprehensive Plan; non-retail uses, however, are permitted within the district to complement and support the retail purposes.
