Placer County, CA Fence Regulations: Permit Requirements (2026)

Placer County adopts the California Building Code (CBC) through its Building and Construction Code (Article 15.04 of the County Code). Under CBC Section 105.2, fences not over seven feet (2,134 mm) high are exempt from a building permit. The same provision states that exemption from a building permit does not authorize work that violates other laws or ordinances of the jurisdiction, so a fence still must comply with the Placer County Zoning Ordinance height and setback limits in Section 17.54.030. Fences taller than seven feet, retaining walls supporting a surcharge, and walls over a certain height generally require a building permit and engineering review. Separately, exceeding the zoning height limits for a setback area requires a discretionary variance from the Zoning Administrator under Section 17.60.100, regardless of whether a building permit is needed. Pool barrier fencing must also meet safety-code requirements. Property owners should contact Placer County CDRA Building Services to confirm whether a permit is required for a specific fence or wall and to verify that the proposed location and height meet zoning standards before construction.
