Los Angeles FAQ
Can I install motion-activated floodlights?
Yes, if fully shielded and aimed within your property so the bulb is not directly visible from the neighbor's yard or the street. Bare unshielded floods violate LAMC §93.0117.
What if my neighbor's lights shine into my window?
File a complaint with LADBS Code Enforcement. Inspectors will evaluate whether the fixture violates §93.0117 shielding rules and issue an order to retrofit or aim the light.
Norwalk FAQ
My neighbor's security light shines into my bedroom. What can I do?
File a written light-trespass complaint with LA County Code Enforcement under Title 22.140.385. Inspectors measure spill at the property line and order the neighbor to add shielding or redirect the fixture.
Can I install motion-activated floodlights at my home?
Yes, with proper shielding and downward aim. The fixture must be full cutoff, the spill at the property line cannot exceed 0.5 foot-candles, and the light must shut off within ten minutes of motion ceasing.
