Riverside's municipal code includes outdoor lighting standards designed to reduce light pollution and protect the night sky. Riverside County Ordinance 915 establishes requirements for shielded fixtures and limits on upward light emission. New development in the city must submit lighting plans showing fully shielded, downward-directed fixtures. The proximity of Mount Palomar Observatory has historically influenced lighting regulations in the region.
Riverside enforces outdoor lighting standards through building codes and zoning regulations. New exterior lighting must use fully shielded (full-cutoff) fixtures that direct light downward. Maximum wattage and lumen limits may apply in residential zones. Motion-sensor lighting encouraged for security. Commercial lighting must not spill onto adjacent residential properties. Parking lot lighting has specific pole height and coverage requirements. Some jurisdictions adopt International Dark-Sky Association recommendations. LED lighting must meet color temperature guidelines, typically 3000K or below to reduce blue light emissions.
Non-compliant fixtures: notice to correct within 30 days. Failure to comply: fines $100 to $500. Commercial violations: permit revocation possible. Repeat offenders: daily fines.
