San Mateo does not have a dedicated dark sky ordinance. Outdoor lighting on new development is regulated through the zoning code to minimize glare and light trespass. California Title 24 energy code sets efficiency requirements for outdoor lighting.
The City of San Mateo does not have a standalone dark sky ordinance. Outdoor lighting for new development is regulated through the zoning ordinance and site plan review process. New development must provide exterior lighting that is directed downward and shielded to minimize light spillover onto neighboring properties. The California Building Code Title 24 energy provisions regulate outdoor lighting wattage and efficiency. Light trespass that creates a nuisance may be addressed through code enforcement. San Mateo's urban/suburban character on the Peninsula means it does not have the same dark sky concerns as rural areas.
Non-compliant lighting on new projects may delay permits. Light trespass nuisance complaints handled by Code Enforcement.
