Showing ordinances that apply to Loma Mar, CA
Loma Mar is an unincorporated community (population 134) in San Mateo County, California. Because Loma Mar is not an incorporated city, it does not have its own municipal code. Instead, San Mateo County ordinances apply directly to properties here. The carport rules rules below are the ones that govern your area.
Unincorporated San Mateo County requires building permits for carports regardless of size. Zoning Regulations set setback, height, and lot coverage limits. Typically 5-foot side setback, 20-foot front setback, max 15 feet height in residential zones.
San Mateo County Building Regulations require a building permit for all carport construction, whether attached, detached, or prefab/kit. Carports are classified as accessory structures in Zoning Regulations §6117. Typical residential zone requirements: minimum 5-foot setback from side property lines, 10 feet from rear, 20 feet from front (or matching primary structure front setback), maximum height 15 feet. Lot coverage maximums (typically 35-40% in R-1 zones) count carports toward total coverage. Materials must meet California Building Code for wind (85 mph exposure C on Peninsula, 110+ mph on coast) and seismic loads. Detached carports over 120 sq ft generally require permit. Prefab metal kit carports — common at hardware stores — still require permit and proper anchoring per manufacturer specs. HOA communities (Emerald Hills subdivisions) may prohibit or restrict carports. Coastside properties may face additional design review under LCP.
Unpermitted carports: stop-work order, retroactive permit with 2x fee penalty, or removal required. Setback violations: relocation or variance required. Fines $250-$2,500. Inadequate anchoring leading to wind damage: liability for neighbor property damage.
