Portsmouth, VA Building Setbacks & Zoning: Setback Rules (2026)

2-218(1) in Sec. 2-218(G) sets minimum yard setbacks separately for each of the city's four base residential districts: Neighborhood Residential (NR), General Residential (GR), Urban Residential (UR), and Urban Residential-Mixed (UR-M). In the NR district, the standard is a 40-foot front yard, 10-foot side yard, 15-foot corner or end side yard, and a 40-foot rear yard, reflecting the district's large 30,000-square-foot minimum lot size. Front yard minimums step down with density: 30 feet in GR, 25 feet in UR, and 10 feet in UR-M. Side and rear yard setbacks vary further by housing type in GR, UR, and UR-M, permitting a zero-foot side yard for attached townhouse walls while detached homes and other uses keep a wider separation.

Sec. 2-218(A)(3) allows front and side yard setback averaging for single-family detached dwellings: an interior lot may use the average setback of the two neighboring residences, and a corner lot may match the setback of the adjoining lot, so long as any averaged side yard stays at least 5 feet. Certain features may still encroach into a required setback, including driveways, uncovered porches (up to 6 feet into the front setback), carports (up to 18 feet into the front setback), and privacy fences that meet the standards in Sec.

2-305. Corner lots must additionally preserve a sight triangle under Sec. 2-218(A)(6), limiting fences and other obstructions to 3 feet in height within 30 feet of the corner. New construction is reviewed for setback compliance at the Zoning Permit (Sec. 2-530) or Site Plan (Sec. 2-540) stage before a permit issues.
