San Diego County's Light Pollution Code and general nuisance provisions address light trespass — unwanted light spilling onto neighboring properties. Outdoor lighting must be directed downward and shielded. Excessive light affecting neighbors may be cited as a nuisance.
The County's Light Pollution Code requires all outdoor lighting fixtures to be fully shielded and directed downward to minimize light trespass to adjacent properties. Section 51.202 establishes general requirements for outdoor lighting in unincorporated areas. Outdoor lighting that creates a nuisance for neighboring properties may be addressed through Code Compliance. Security lights, sports lighting, and commercial lighting must be designed to minimize off-site impacts. The Light Pollution Code's three-zone system provides specific maximum illumination levels at property lines. Residents experiencing light trespass can file complaints with County Code Compliance. Solutions include fixture repositioning, adding shields, adjusting angles, or reducing wattage.
Light trespass complaints are investigated by Code Compliance. Violations may result in required fixture modifications. Persistent violations may lead to fines.
