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

04, Article VI of the Norwalk Municipal Code governs mixed use developments, projects that combine residential units with commercial, office, or other nonresidential floor area. 560, titled 'Lighting,' sets two linked standards that the Community Development Department checks during site plan and precise development plan review. Subsection A requires every project to provide adequate lighting for security and visibility, specifically along walkways and driveways, at entrances to parking areas, and throughout open space areas, so pedestrian routes and common areas stay illuminated after dark. Subsection B is the light-trespass control: lighting must be designed to minimize glare and light spillover onto adjacent properties, meaning fixture placement, shielding, and aiming have to keep illumination on the project site rather than washing across a neighboring yard, business, or window.

The section sets no numeric foot-candle cap; instead it directs designers to control fixture placement, shielding, and orientation so spillover is minimized, and staff evaluate submitted lighting plans against that standard before approving a project. The provision was carried forward in the citywide zoning code update adopted by Ordinance 25-1764 on December 16, 2025. 560 sits specifically in the Mixed Use Developments article, it governs projects reviewed under that classification; other development types elsewhere in Title 17 are subject to whatever lighting or screening conditions are imposed through their own discretionary review process.

A property owner who believes a neighboring mixed-use project's lighting is spilling onto their land can raise the issue with Community Development, which can require refitting or reshielding fixtures as a condition of maintaining the approved plan.
