El Monte FAQ
What does fully shielded mean?
The fixture must direct all light downward with no light emitted above the horizontal plane. This prevents glare and sky glow while still providing ground illumination.
Can my neighbor's lights shine into my yard?
Most codes prohibit light trespass onto neighboring properties. Contact El Monte code enforcement if outdoor lights from adjacent properties create a nuisance.
Los Angeles FAQ
Do I need to replace my existing lights?
No. Pre-existing fixtures are grandfathered. Replacements, new permits, and tenant improvements that touch the electrical system must comply with §93.0108.
Are holiday lights exempt?
Yes. Temporary seasonal lighting is exempt November 15 to January 15 if pointed downward.
What color temperature is allowed?
New outdoor LEDs are capped at 3000K. Warm-white 2700K is recommended for hillside and residential areas.
