Irvine's lighting standards under Zoning Code Chapter 3-16 prohibit outdoor lighting from creating glare or light trespass onto neighboring properties. New development must demonstrate that lighting is contained within the property. Residents can file complaints about light trespass through code enforcement. HOA communities may have additional lighting standards.
Irvine codes prohibit light trespass, defined as artificial light that illuminates areas beyond the property where the fixture is installed. Residential properties typically must keep light levels below 0.5 to 1.0 foot-candles at the property line. Security lights must be aimed and shielded to illuminate only the owner's property. Floodlights aimed at neighboring homes are prohibited. String lights and decorative lighting must not create glare for neighbors or passing traffic. Holiday lighting may have temporary exemptions. Commercial properties face stricter standards with measured lumen limits at property boundaries.
Light trespass complaint: warning and 30-day correction period. Non-compliance: fines $100 to $300 per violation. Repeated complaints: escalating fines. Commercial violations: up to $1,000.
