SLC lighting ordinance (21A.36.290) requires full-cutoff fixtures and lumen caps to reduce light pollution.
All new exterior lighting must be full-cutoff (no light above horizontal) and meet maximum lumen densities per zone. Residential properties are limited in total outdoor lumens; commercial properties have stricter limits near residential zones. Uplighting is generally prohibited except for flags and permitted architectural features. Foothill areas have enhanced dark-sky provisions to protect views.
Contact your local code enforcement office for specific penalty information.
