Yuba City, CA Outdoor Lighting: Light Trespass (2026)

There is no dedicated light-trespass ordinance or footcandle spillover limit in the unincorporated Sutter County Zoning Code. The most directly applicable enforceable standard appears in the sign chapter: Section 1500-21-040(C) requires that external sign light sources be directed and shielded to limit direct illumination to the sign area only, and that illuminated signs not be of an intensity or brightness that creates glare or other negative impacts on residential properties in direct line of sight. For development projects, lighting and glare are treated as operational/performance and design considerations: Section 1500-25-040 (Design Review) allows the county to evaluate lighting as part of commercial, employment, and multifamily project review, and Section 1500-25-060 lists light and glare among the operational/performance standards that can be addressed through the variance process. Outside the sign and project-review context, there is no specific residential-to-residential light-trespass metric in the code; persistent light spillover that substantially interferes with a neighbor's use of property may be addressed under general county nuisance authority or, for new construction, through Title 24 lighting-control and shielding requirements. Residents experiencing light trespass should contact Sutter County Development Services / code enforcement to determine whether a specific provision applies.
