Perris, CA Outdoor Lighting: Light Trespass (2026)

The Perris Municipal Code does not set a specific maximum foot-candle of spillover at residential property lines, but it does require that lighting be aimed to avoid trespass onto neighbors. Section 19.69.030 (within the parking and loading standards, Chapter 19.69) provides that any illumination, including security lighting, shall utilize full-cut-off fixtures and be directed away from adjoining properties and the public right-of-way; it also requires a minimum of one foot-candle maintained across the parking surface for safety and that lighting standards be energy efficient and in scale with the structure. For commercial and other signs, Section 19.75.160 requires signs with external illumination to use fully shielded lighting fixtures and caps illuminated signs at a maximum luminance of 750 cd/m2 (nits) at night, holding that level from one-half hour before sunset until sunrise. Glare or spillover lighting that becomes a nuisance to neighboring residents may also be addressed through the city's general nuisance authority (Title 7) and through site-plan and design-review conditions imposed on new development. Because there is no standalone exterior-lighting ordinance, the practical standard for light trespass in Perris is shielded, downward-directed fixtures aimed away from neighbors; residents experiencing significant glare from a property should contact Municipal Enforcement Services / Code Enforcement.
