Thousand Oaks prohibits outdoor lighting that unreasonably spills onto neighboring properties. Light trespass is addressed through the city's nuisance ordinance and development code lighting standards. Complaints are handled by code enforcement.
Light trespass, where outdoor lighting from one property shines unreasonably onto an adjacent property, is regulated under TOMC nuisance provisions and Chapter 9 development standards. New construction must include lighting plans showing that fixtures will not cast light beyond property boundaries. Existing properties creating light trespass through poorly aimed floodlights, unshielded fixtures, or excessively bright lighting may receive code enforcement complaints. The city evaluates complaints based on the reasonableness of the light impact, considering fixture type, aiming, intensity, and time of operation. Residents experiencing light trespass should first discuss the issue with their neighbor before filing a complaint. Code enforcement can require the offending property to shield, redirect, or remove problematic fixtures. HOAs in Thousand Oaks often have their own exterior lighting standards that supplement city requirements.
Persistent light trespass after a complaint is filed may result in code enforcement citations. Fines escalate for repeated violations. The property owner may be required to modify or remove the offending fixture at their expense.
