Brentwood, CA Outdoor Lighting: Light Trespass & Shielding (2026)

200 (Office and Commercial Zones, General Regulations), folds light trespass into the same paragraph as heat and humidity nuisances. 2 requires that any operation producing glare be conducted inside a completely enclosed building, and it sets a hard numeric ceiling: light on the lot shall not cause illumination in excess of one-half foot-candle when measured at the lot line. Exposed light sources must be shielded, and any flickering or unusually intense source is separately barred from causing a nuisance across lot lines. 002, these performance standards apply to every office and commercial zone in the city, CO, COB, COR, CR, C-1, C-2 and C-3, unless a specific zone's chapter says otherwise, so a car lot on Brentwood Boulevard and a professional office building downtown are held to the identical half-foot-candle line.

004 require compliance with San Francisco Bay Area Air Pollution Control District rules for smoke and odor, so this section functions as Brentwood's general commercial nuisance-performance chapter, not a stand-alone lighting ordinance. Because the standard is tied to the zoning code, the community development department enforces it through the same code-enforcement process used for any other zoning violation, and a property found exceeding the half-foot-candle limit at the property line can be required to shield or redirect its fixtures to come back into compliance.
