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

Section 23.78.080 of the Placentia Municipal Code sits in Chapter 23.78 (Off-Street Parking) and is the provision that keeps parking lot light from crossing onto a neighbor. It says any lights provided to illuminate parking areas must be so arranged as to reflect light away from the public right-of-way and from any adjoining residential premises. The duty falls on whoever builds or operates the off-street parking area. The section prints no foot-candle limit, no mounting height, no shutoff time and no fixture type. The test is the direction of the light: it has to point away from the street and away from adjoining homes.

The neighboring section on walls works with it. When a parking area abuts a residential zone, Section 23.78.090 requires a solid masonry wall 6 feet in height along the abutting property line that is the zone boundary, erected by the developer of the parking lot. Where that boundary is a side property line, the wall is reduced to 3 feet within the front yard setback area for the abutting residential zone. That wall is a physical screen, not a lighting standard, but it sits at the same residential edge.

The scope is narrow. The text covers lights provided to illuminate parking areas. It does not address porch lights, floodlights or fixtures on a house. An enforcement officer who receives a complaint or sees a violation can act under Section 1.10.030(g), and the code requires a pre-citation courtesy notice before an administrative citation unless the violation creates an immediate danger to life, health or safety.
