Mead Valley FAQ
What does "fully shielded" mean for my outdoor light?
Under Ordinance 655 Sec. 4.J, a fully shielded fixture is built so that all of its light is projected below the horizontal plane through the fixture's lowest light-emitting point - meaning no light escapes sideways or upward.
Is there a county rule for a neighbor's light shining on my property?
Within the Palomar light-pollution zones, Ordinance 655's shielding and curfew rules apply. Outside those zones the County has no general numeric trespass standard, and such disputes are usually handled as a private nuisance matter.
Temecula FAQ
My neighbor's floodlight shines into my bedroom — what can I do?
Talk to them first. If unresolved, file a Code Enforcement complaint (951-694-6480). Officers will measure footcandles at your window. Over 0.1 footcandles violates TMC 17.30 and they'll be required to correct it.
Are motion-activated security lights allowed?
Yes, and preferred over continuous lighting. Aim them within your property, use shielded fixtures, and set short timer durations (1-5 minutes) to minimize neighbor impact.
Can I uplight my house or trees?
Limited uplighting for architectural or landscape features is allowed if shielded to prevent direct sky glow and not creating off-site trespass. Avoid lighting that crosses property lines or shines into windows.
