Utah County's Land Use Ordinance Chapter 10 requires fully shielded, full-cutoff outdoor fixtures in most zones with lumen caps per acre and a 3000K max color temperature for residential areas. Utah is an international dark-sky leader with several nearby IDA-certified places driving regional standards.
Utah County's Land Use Ordinance outdoor lighting standards require new nonresidential and multi-family exterior lighting to use full-cutoff (IES-defined) luminaires emitting zero lumens above 90 degrees from nadir. Maximum lamp correlated color temperature is 3000K. Lumen-per-acre caps apply by zoning district, with tighter limits in agricultural and residential zones. Provo City Code §14.38 (Outdoor Lighting) and Orem City Code Chapter 22-6 impose similar full-cutoff requirements. Canopy lighting at gas stations and drive-throughs must be fully recessed. Parking lot pole heights are generally capped at 25 feet in residential-adjacent areas. Utah County sits near several International Dark-Sky Association designations (Antelope Island, Jordanelle, Goblin Valley) and the state has codified dark-sky friendly guidance in UAC R309 adjacent guidance. Upward-aimed architectural uplighting, sky beamers, and laser displays are prohibited without special permit.
Non-compliant fixtures on new construction: certificate of occupancy withheld until corrected. Existing non-compliant commercial lighting: notice to correct within 30–60 days, then fines $100 to $500 per day. Sky beamers without permit: immediate shutdown and $500 citation.
