No statewide law
Utah
Last checked October 29, 2026
Utah has no statewide outdoor lighting statute that we could find. The legislature has only urged action: SCR 1 (2003) and SCR 2 (2018) encourage full-cutoff or shielded fixtures but set no requirements. Binding rules are local: Moab (shielded, 3,000 K maximum, lumen caps), Hideout (2022, fully shielded, 3,000 K), and Park City (2021 code).
