Address Assignment

Based upon the PWC code, chapter 24, the GIS Office uses a uniform numbering system for addressing properties and buildings within the County. Addresses must be whole numbers and consist of no letters or fractions. There are three (3) different types of addresses:
 
  • Parcel addresses are assigned to a single piece of land. 
  • Premise addresses are assigned to buildings and/or units that are located on a parcel of land. 
  • Unoccupied Structure addresses are assigned to freestanding or attached structures that are not meant to be occupied as residential or commercial space but require permits or a phone. Examples are retaining walls, cell towers, signs, meters and many more.
 
In cases where the parcel of land contains a single structure that is owner-occupied, the parcel address and premise address are the same. In cases where many structures are located on the same parcel (such as apartment complexes or business parks), the premise address will be different than the parcel address.
 
Buildings with multiple units will have one address for the main entrance with a unit, apartment or suite number to identify each separate unit. Houses or single tenant buildings have one address for the entire structure. 

Properties that are located on a corner lot will be addressed off of the street in which the property is accessed (via driveway or parking lot entrance).
 
Most new addresses are assigned as development occurs and are created by the GIS Office during site plan review prior to the final approved plan. It is the responsibility of the engineer or developer to provide the County addresses to the architect for annotation on any architectural plans. Architects can send the GIS Office a copy of the plan cover sheet and tenant layout prior to submittal and GIS will verify, free of charge, the addresses shown on the plans to avoid future addressing, permitting or inspection issues related to addresses.  Information can be emailed to pwcmaps@pwcgov.org  or call 703-792-6840 for more information.
 
Addresses can also be assigned outside of the Plan Review process. These include, but are not limited to, the following situations and will require the owner to visit GIS before any permits can be issued. At that time, GIS will assign an address and sign off on validation.
  • Subdivisions with lots greater than 10 acres
  • New street creation or street renaming
  • Temporary addresses for Construction Trailers, Seasonal Stands, etc. A copy of the approved site plan showing the location drawn to scale is required to scale by the Prince William County Zoning Department for permitting purposes.
  • Unoccupied structures not tied to a specific parcel or owner. A copy of the plan identifying the location of the structure is required.
