Monterey County, CA Fence Regulations: Material Restrictions (2026)

Monterey County does not publish a simple list of banned fence materials in its FAQ, but it does treat materials differently for permit purposes, which functions as a de facto restriction by height. The Building & Planning Services FAQ exempts from a building permit "concrete and masonry fences not over 6 feet high, wood, vinyl and metal fences not more than 8 feet high and open metal fences not over 10 feet high." Heavier or solid materials (concrete/masonry) get the lowest exempt height because of structural and engineering concerns, while lighter and more transparent materials (open metal) get the most. Beyond the exempt heights a construction permit and engineering may be required. Where appearance matters most, parcels in a Design Control District must obtain a Design Approval, which reviews materials, finishes and visual compatibility, so even an exempt-height fence may face material conditions in those overlays. Coastal Zone parcels can face additional scenic and Coastal Development Permit review under Title 20. For exact material rules in your zoning district or overlay, the County directs applicants to HCD Planning.
