Interpretations of the Zoning Ordinance

zoning questionsAn interpretation of the Zoning Ordinance is a written or verbal determination made by the Zoning Administrator that explains the applicability of specific provision(s) of the Fairfax County Zoning Ordinance based on the set of facts presented in the request. These requests may include use determinations, questions on the placement or use of buildings or structures, and a variety of other zoning-related questions. 

Before submitting a request

Have you called our Planner of the Day (POD)? Many questions do not require an interpretation and can be answered over the phone by our POD staff at 703-324-1314 or by email at ORDAdmin@fairfaxcounty.gov. If you have basic questions on what a use may be, applicable yards or setback requirements, if a proposed use or structure is allowed in a specific zoning district and under what permissions, and other general zoning-related questions, please contact our POD.
