Summary
Most residential fences do not require a building permit, but zoning approval is mandatory for every new fence installation. A building permit is required when a fence serves as a swimming pool barrier or for pedestrian protection.
Fence maximum height is 42 inches (3.5 feet) for the front yard and the side of your yard that faces a street. Side and rear yard fencing is generally allowed up to 6 feet.
Full Breakdown
Prince William County states that most residential fences do not need a building permit, but zoning approval is mandatory for all new fence installations to confirm compliance with height and setback rules under Zoning Ordinance section 32-300.02.3. A building permit is required if the fence is intended for swimming pool safety or pedestrian protection. Apply through Development Services; the independent cities of Manassas and Manassas Park issue their own permits separately.
Violations & Fines
