South Jordan, UT Outdoor Lighting: Light Trespass (2026)

South Jordan's exterior lighting standards under Title 17 specifically address glare and spillover. Light trespass — defined as light cast beyond the property line onto adjacent properties — must be controlled to maintain low illuminance values at residential property lines (commonly a maximum of 0.1 foot-candles measured at the boundary of residential uses, and up to 0.5 fc at commercial boundaries). Fixtures generating glare (direct view of a bare lamp or bright source) visible from a neighboring residential window or adjacent public roadway are prohibited. Common remedies include installing full-cutoff fixtures, reducing wattage, repositioning/aiming lights downward, adding side shielding, adding timers or motion sensors so lights are on only when needed, and landscape screening. Temporary construction lighting must be aimed away from dwellings and generally shut off by 10 PM. Complaints of glare or spillover can be filed with Code Enforcement, which will typically inspect at night. Repeated or unresolved violations can result in citations. Neighbor-to-neighbor disputes over yard lighting are common in Utah suburbs and often resolved through HOA architectural committees or direct conversation before code enforcement escalation.
