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.
