Elk Grove FAQ
My neighbor's floodlight shines in my bedroom — what can I do?
Ask them politely first, then file a Code Enforcement complaint if it persists. It may qualify as a nuisance or violate Title 23 trespass limits.
Are motion-activated security lights allowed?
Yes, and they are encouraged over continuously-on floodlights because they naturally reduce light trespass.
Isleton FAQ
What can I do about a neighboring apartment or business shining light onto my property?
Sections 5.4.3 and 5.9.4.G require multifamily and commercial/parking lighting to be fully shielded and aimed so no fixture illuminates off-site. You can report spillover to Sacramento County Code Enforcement; for parking areas the standard even applies to existing businesses.
Does the code limit light trespass from a single-family home?
There is no specific fixture requirement for single-family homes. Glare or spillover from a neighbor's residential lighting is generally addressed as a nuisance through code enforcement rather than a dedicated lighting standard.
