Virginia Beach, VA Fence Regulations: Retaining Walls (2026)

Retaining walls in Virginia Beach are regulated by the Department of Planning and Community Development and the Permits and Inspections Division. Per VUSBC Section R404 and the Virginia Residential Code, any retaining wall exceeding 3 feet in height (measured from bottom of footing to top of wall) requires a building permit. Walls supporting a surcharge such as a sloping backfill, driveway, structure, or swimming pool require a permit regardless of height. Walls over 4 feet or with surcharge loads require engineered plans sealed by a Virginia-licensed professional engineer showing soil analysis, wall geometry, reinforcement, and drainage. Virginia Beach's coastal location creates special conditions: walls within the Chesapeake Bay Preservation Area Resource Protection Area (RPA) or Resource Management Area (RMA) require CBPA review and may need variance approval. Walls within designated dune areas are subject to Coastal Primary Sand Dunes and Beaches Act restrictions enforced under Virginia Code §28.2-1400 et seq. and require Wetlands Board approval. Setbacks from property lines typically match fence setbacks (see fence-requirements). Proper drainage is critical: French drains, weep holes every 4-6 feet, and geotextile fabric behind the wall prevent hydrostatic pressure buildup. Timber walls must use pressure-treated lumber rated for ground contact. Segmental retaining wall (SRW) blocks are common and must be installed per manufacturer specifications. Inspections are required at footing, reinforcement, and final stages for permitted walls. Neighbor notification is recommended when walls are near property lines, though not legally required unless a variance is sought.
