Galt FAQ
My neighbors floodlight shines into my bedroom, what can I do?
Start with a polite conversation. If unresolved, file a complaint with Galt Code Enforcement describing the fixture and impact.
Can Galt measure light levels at my property line?
Code enforcement may use a light meter for serious commercial complaints. Residential cases typically rely on observed spillover rather than formal metering.
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.
