Summary
Thousand Oaks requires perimeter and floodlighting on commercial and industrial property to be hooded or shielded so no direct beam crosses onto a public street or a neighboring parcel. The rule sits in the zoning code's general commercial and industrial standards, not a standalone lighting chapter.
Perimeter or floodlighting, whether used for illumination or advertisement, which illuminates private land, whether improved or not, shall be permitted only when such lighting is installed on private property and is hooded or shielded so that no direct beams therefrom fall upon public streets, alleys, highways, or private property.
Official source re-checked September 7, 2026: no newer edition of the code had been published (publisher’s edition: 2026 S-78: 2026 S-78 Supplement contains: Current city legislation passed through March 31, 2026).
Full Breakdown
2309(d), perimeter or floodlighting on private land in commercial and industrial zones, whether it is used for illumination or for advertising a business, is only allowed if it is installed on private property and is hooded or shielded so that no direct beams fall on public streets, alleys, highways, or private property. The Community Development Department reviews lighting as part of the sign and site plan permit process for commercial and industrial parcels, and a fixture that throws unshielded glare across a property line does not meet this standard even if the light source itself sits legally within the site.
Thousand Oaks does not run a general nuisance-light ordinance for residential yards; the codified fix-at-the-source rule lives here, tied to commercial and industrial development standards under Article 21 of the zoning code (Chapter 4, Article 23, governing signs and general commercial/industrial requirements). Property owners installing floodlights, wall packs, or pole-mounted fixtures near a shared boundary or a public right-of-way should specify full cut-off or shielded fixtures at the outset, since retrofitting shielding after a code complaint is the typical enforcement outcome rather than a fine on first contact.
2528(b)(3)(iii), which separately caps light standard height at fourteen feet and requires full cut-off fixtures to control glare and light trespass for that use type.
Violations & Fines
A property found in violation is directed to install hooding, shielding, or fixture replacement to eliminate the direct beam crossing the property or street line; the Community Development Department can condition or withhold sign and site permits until the lighting complies. Continued noncompliance after notice exposes the property to the city's general municipal code enforcement process, including administrative citations, under TOMC Chapter 1's public nuisance and enforcement provisions.
