Address Validation and Permits

Address Validation by the GIS Office is required on all commercial properties including alteration/repairs when applying for a permit.  The two types of address validations are for all commercial properties, and address validations for freestanding signs. GIS will validate any address for a property owner, business or developer. Address Validations are free of charge.

bldg-permit2.jpgAddresses are validated by the GIS Office to ensure the proper location and sequencing of numbers for tenant spaces or structures. Staff verifies the address and space location with the use of approved site plans, tenant layouts and recorded plats. Address validation is the first step in the permitting process and ensures that all of the permits obtained are issued under the correct address. When you need multiple addresses verified in person, especially for new structures, we may request that you return at a later time/date. We appreciate your understanding as we try to provide all our customers with timely service.  It is highly recommended, in these cases, that you submit your request electronically (see address validation questionnaire above) a few business days prior to visiting the county for other services.

Once processed, the address validation may be emailed to you or can be picked up at the GIS Office. If you choose to come in person, please contact our office before arriving to ensure that we have received all of the required information and that your validation will be ready for pick up.

Address Validation for Commercial Use

In order to provide fast and efficient service, GIS staff can process your address validation via email. Please complete address validation form and email it to Please refer to the checklist for the required information/paperwork needed.

Address Validation for Freestanding Signs

Address Validation is the first step in the permitting process for all freestanding signs. The GIS Office will assign an Unoccupied Structure Code Address to each sign. The signs are plotted out geographically based on their location on the site plan that is submitted.

Please complete and submit the fillable address validation form for freestanding signs. The form contains three requirements in order to process the address validation. They include: attaching an image of the sign(s) that shows the display, a site plan indicating the exact location of the sign(s), and completing the questionnaire with regards to sign and contact information.

  • If there are multiple signs on a single parcel of land, you may submit one address validation freestanding sign questionnaire.
  • If you have multiple signs on multiple parcels of land, you will be required to submit an address validation freestanding sign questionnaire for each parcel of land.

Upon completion, a copy of the address validation will be sent to you as well as to Zoning and Building Permits office. Zoning is the next step in the process. Please contact the office at (703) 792-6830 on how to proceed.

Unoccupied Structures  

Unoccupied structures need addresses assigned for permitting purposes only and are not required to be posted. However, the unoccupied structure address should be displayed on any related applications or plans. Examples of unoccupied structures are retaining walls, cell towers, electrical boxes, light meters, signs, utility rooms and many more. GIS will be your first stop in the development services processes to get your unoccupied structure address assigned.

If the structure is freestanding, the GIS Office assigns an address with an unoccupied structure code. In some cases the structure is attached to a building so the building address along with the unoccupied structure code will make up the unoccupied structure address (3900 Fettler Park DR ULM001). In other cases, the structure may be related to the parcel address along with the unoccupied structure code.
