Gardena addresses light trespass through the exterior-lighting provisions of Gardena Municipal Code Chapter 18.42, which require security lighting not to be directed beyond property lines and require sign illumination visible from a residential zone to be shielded so light does not spill into that zone.
GMC 18.42 states that security lighting shall not be directed beyond the property lines, the core light-trespass standard for the city. Exterior fixtures must be enclosed on the top and sides to control spill, and all external sign lighting must be hooded and directed onto the sign face and away from adjacent properties. Where a sign is visible from a residential zone, its illumination must be shielded to minimize the flow of light into the residential zone. For multifamily, commercial, and industrial projects, lighting plans reviewed against these standards are required with site development plans. Persistent glare or spillover onto a neighboring property can also be pursued as a nuisance under the city's code-enforcement authority.
Lighting aimed past property lines or unshielded illumination reaching a residential zone can be cited during review and abated as a nuisance.
