Palm Springs, CA Outdoor Lighting: Dark Sky Rules (2026)

PSMC Chapter 93.21 (Outdoor Lighting) is among the most comprehensive dark-sky ordinances in California. All new and replacement outdoor lighting must use fully-shielded (full cutoff) fixtures that emit no light above the horizontal plane of the lamp, have correlated color temperature of 3000K or lower (warm white), and fall within lumen caps set by property type and size (residential typically capped at a few thousand lumens per lot). Uplighting of buildings, trees, and landscape features is severely restricted or prohibited outside of specifically exempted architectural applications. Floodlights, barn lights, and exposed-bulb fixtures are generally not allowed. Lighting may not cause glare or light trespass onto adjacent properties, with measurements at the property line typically capped at 0.1 foot-candles. Pool and spa lighting is exempt if not visible from off-site. Holiday lighting is exempt November 15 through January 15. Commercial and resort properties have specific standards and often require photometric plans with permit submittal. The ordinance supports Mt. San Jacinto view preservation, protects migratory birds and desert wildlife, and preserves the night sky that draws stargazers and contributes to the city's resort character. Violations can result in retrofit orders and fines.
