Pomona Permit Requirements Rules (2026): What You Need to Know

Pomona's fence permit requirements are governed by a combination of the locally adopted California Building Code and the city's zoning ordinance (Article VIII). Under the California Building Code as adopted by Pomona, fences constructed of wood, chain link, vinyl, or wrought iron that do not exceed 6 feet in height are generally exempt from building permit requirements. This exemption covers the most common residential fence installations. However, even permit-exempt fences must comply with all applicable zoning standards, including height limits by yard location, prohibited materials in residential zones, and sight-visibility requirements on corner lots.

Masonry walls — including concrete block, brick, stone, and stucco-over-block construction — that exceed 4 feet in height require a building permit from the Pomona Building Division. The permit application must include structural engineering drawings prepared and stamped by a California-licensed structural engineer, demonstrating the wall's ability to withstand seismic and wind loads. This requirement reflects California's seismic hazard and the structural risk posed by unreinforced masonry walls. Retaining walls over 4 feet in exposed height similarly require a building permit with engineering.

The Pomona Planning Division may also require a zoning clearance before fence installation, particularly for fences in the front yard setback, fences on corner lots, or fences in overlay zones with special design standards. Residents planning fence installation should contact the Building Division at (909) 620-2191 or the Planning Division at (909) 620-2191 to confirm requirements before beginning work. When a fence is built on or near a property boundary, it is advisable to obtain a professional boundary survey to ensure the fence does not encroach on neighboring property.
