Summary
Thousand Oaks has no citywide dark-sky ordinance, but its self-storage facility standard mandates full cut-off, shielded fixtures capped at 14 feet and bans low-pressure sodium and mercury-vapor lamps. A near-identical shielding rule applies to backyard residential sports-facility lighting.
(iii) Lighting. The use of lighting must be integrally designed as part of the built environment and should reflect a balance of the lighting needs for the self-storage facility and surrounding nighttime characteristics of the community. aa. Lighting should be designed to minimize glare and light spillover and maximize energy conservation. bb. Full cut-off fixtures reduced mounting heights, and the use of shielding should be utilized to effectively control glare and light trespass. cc. Maximum height of any light standard shall be fourteen (14') feet. dd. Low pressure sodium and mercury vapor lamps are prohibited. ee. Photometric plans are required with all applications requesting self-storage facility lighting.

Full Breakdown
There is no general outdoor-lighting or dark-sky ordinance that applies to ordinary Thousand Oaks homes or businesses. The shielding language exists only inside special use-permit standards for specific facility types. TOMC Sec. 2528(b) sets development conditions for self-storage facilities, which are only permitted as a primary use in the M-1 and M-2 industrial zones with an approved Special Use Permit. Subsection (b)(3)(iii) requires that lighting be integrated into the site design and minimize glare and spillover onto neighboring uses. It then gets specific: full cut-off fixtures and reduced mounting heights are required to control glare and light trespass, no light standard may exceed 14 feet, low-pressure sodium and mercury-vapor lamps are prohibited outright, and a photometric plan is a required part of any application proposing self-storage lighting.
The Community Development Director reviews that photometric plan as part of the Special Use Permit process under Article 18. The city applies the same design philosophy elsewhere on a narrower scale: TOMC Sec. 2524(b)(1), covering backyard residential sports facilities like tennis or pickleball courts, likewise requires full cut-off fixtures, shielding, a 14-foot maximum light-standard height, and bans on low-pressure sodium and mercury-vapor lamps. Outside these two use-specific standards, a homeowner or ordinary commercial property in Thousand Oaks is not subject to a fixture-shielding or lamp-type mandate under the Municipal Code.
Violations & Fines
Installing non-compliant self-storage lighting, such as fixtures without full cut-off shielding, exceeding the 14-foot height cap, or using a banned lamp type, is a condition violation of the facility's Special Use Permit, which the City can enforce or revoke. It is also a Municipal Code violation under TOMC Sec. 1-2.01/1-2.03, carrying an infraction fine of $100 to $500 depending on repeat offenses within a year, or a misdemeanor charge of up to $1,000 and six months in jail, with each day of noncompliance a separate offense.
