Bellflower, CA Outdoor Lighting: Light Trespass (2026)

Bellflower does not set a numeric light-trespass limit (such as a maximum foot-candle measurement at a property line). Instead, light spilling onto a neighbor's property is addressed through the same glare-and-shielding requirements found throughout the Bellflower Municipal Code. Zoning chapters such as the M-1 Light Industrial District (Chapter 17.52) and the Open Space Zoning District (Chapter 17.64) require exterior lighting to be arranged and shielded so as to prevent glare on adjacent properties or highways. The Development Review standards (Chapter 17.80) instruct the city to avoid approving structures or improvements that would cause undue glare impacts on adjacent properties, and to protect the privacy of neighbors and the amount of sunlight reaching adjacent buildings and exteriors. For illuminated signs, the Director may require a photometrics plan to ensure light and glare are shielded or directed so as to prevent glare on adjacent properties or highways. In practice, a resident bothered by a neighbor's floodlight would raise the issue through code enforcement under these glare provisions; the remedy is to shield, re-aim, or reduce the fixture so the glare no longer reaches the adjacent property. Owners should confirm current enforcement practice with the Community Development / Planning Division.
