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.
