Layton, UT Outdoor Lighting: Light Trespass & Shielding (2026)

100, "Prohibition Of Undesirable Emissions," bars any use from emitting glare beyond its own lot line and requires commercial, industrial and institutional projects adjacent to residential areas to submit lighting plans for City approval. Under subsection 1, any fixture within 35 feet of a residential boundary is capped at 20 feet in height; fixtures farther than 35 feet away are capped at either the zoning district's main-structure height limit or 35 feet, whichever is less. Light standards must be spaced at least four times their own height apart, and shielding must keep the light source itself from being visible above five feet at any residential property line, while also preventing glare from hitting drivers on adjacent public streets.

Uplighting or spotlighting used to highlight architecture, landscaping or signs must be focused inward toward the site, or angled so no beam crosses onto residential property or into a street. A site plan showing the lighting pattern of every fixture, whether pole-mounted, ground-mounted or building-mounted, must go to the Community and Economic Development Department for approval. Recreational facilities and community uses needing brighter lighting can be exempted from these specific standards, but only by obtaining conditional use approval. Off-street parking lots city-wide must also provide at least one foot-candle of illumination at the pavement while keeping light shielded and directed downward, not spilling onto adjacent properties.
