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

Section 13.20.055, Lighting Standards In Residential Developments, requires a photometric lighting plan for every area of a residential development other than land within individual single-family building lots, covering open space, driveways, parking lots and facilities, walkways, sidewalks, streets, clubhouses and pools. That plan must be prepared and stamped by a recognized lighting engineer or lighting professional applying the latest Illuminating Engineering Society (IES) Lighting Handbook recommendations. Spotlights, reflectors and floodlights may illuminate buildings, landscaping, signs, parking and loading areas only if fitted with lenses or other devices that concentrate the light on those features rather than letting it scatter.

The Code's light-spill rule is explicit: no unshielded light, reflector, spotlight, strobe light or searchlight may point toward or be directly visible from a public right-of-way, all lighting must be shielded and directed downward to avoid spilling beyond the property line, and unshielded exterior wall-mounted floodlights, called wall packs, are prohibited outright. Intensities must be controlled so neighboring areas are not adversely affected by glare or excessive light. Taylorsville applies a parallel light-spill standard to commercial developments under Section 13.23.110, and to development within the Traditional Neighborhood Development overlay under Section 13.12.090, so a light-trespass complaint from a homeowner next to a commercial site or TND project draws on the matching provision for that zone rather than Section 13.20.055 itself.
