Fremont fence rules combine FMC Chapter 18 zoning with Chapter 15 building code, plus Fire Code rules in the Very High Fire Hazard Severity Zone.
Fremont fence requirements draw from three main sources. FMC Chapter 18 (Zoning) sets height, setback, and visibility triangle standards. FMC Chapter 15 (Building) governs permit triggers and structural requirements for walls over 7 feet and retaining walls over 3 feet. FMC Chapter 9 and the California Fire Code apply in the Very High Fire Hazard Severity Zone (VHFHSZ) covering Mission Peak foothills and Niles Canyon, requiring non-combustible materials within 5 feet of structures. Corner lot visibility triangles must remain clear to a 3-foot height within 15 feet of intersections. Fences must be maintained structurally sound; leaning or collapsing fences can be cited as a public nuisance. Master-planned HOAs in Warm Springs Innovation District often require specific styles and colors. Historic Niles fences require HARB review. Good Neighbor Fence Act cost-sharing applies to all shared boundaries.
