Baldwin Park, CA Outdoor Lighting: Light Trespass (2026)

The City of Baldwin Park addresses light trespass (light spilling onto neighboring property) directly in its Zoning Code Performance Standards, Section 153.140.040 (Light and Glare). Subsection (F), Lighting Orientation and Shielding, requires that all lights be directed, oriented and shielded to prevent light from shining onto adjacent properties, onto public rights-of-way, and into driveway areas in a manner that would obstruct motorists' vision. Subsection (G) adds that lighting for advertising signs shall not cause light or glare on surrounding properties, reinforced by the general sign standard (153.170.070) that signs be arranged, operated, shielded and maintained to prevent glare, reflection, nuisance or hazardous interference to abutting properties, streets and walkways. The candle-power limit (153.140.040(C)) requires lighting to be no brighter than necessary, and light sources are kept out of buffer areas except for walkway lighting (153.140.040(E)). These standards apply to all new construction, renovation and alteration in every zone. The City does not set a specific numeric maximum (e.g., foot-candles measured at the property line) for residential light trespass; enforcement is based on the qualitative requirement that light not shine onto adjacent property or the right-of-way. Persistent glare or spillover onto a neighbor can also be addressed as a nuisance. This is a City of Baldwin Park standard, distinct from Los Angeles County's lighting rules that apply only in unincorporated areas.
