Outdoor Lighting in Provo, UT: What Residents Actually Need to Know

If you live in Provo or are thinking about moving there, outdoor lighting are one of those things you probably won't think about until they affect you directly. Provo has 2 specific rules on the books covering different aspects of outdoor lighting, and some of them might surprise you.

Dark Sky Rules

Provo requires new development lighting to be fully shielded, cut-off fixtures aimed downward, bans uplighting outside approved landscaped areas, and requires most outdoor lighting to turn off after business hours.

Key details: Fixture type required: Fully shielded, cut-off. Uplighting: Prohibited without DRC approval. Off-hours rule: Off after business hours. Glare limit: No light above 90° horizontal plane.

Installing unshielded, non-cut-off fixtures or uplighting without Design Review Committee approval violates Section 15.21.030; a development lighting plan lacking the required shielding certification under Section 15.21.020 can be rejected outright, and installed fixtures that don't match an approved plan are subject to Chapter 15.20's site development enforcement process.

Light Trespass & Shielding

Any outdoor lighting plan Provo requires, for everything except one- and two-family dwellings, must certify the fixtures are fully shielded, cutoff types that keep light from spilling above a 90-degree horizontal plane, and parking-lot lights must specifically be shielded to stop direct illumination from crossing onto a neighbor's property.

Key details: Shielding standard: cutoff fixtures, no glare above 90° plane. Parking-lot light height cap: 20-50 ft depending on zone. Illumination ratio cap: 4:1, average to minimum. Exempt uses: one- and two-family dwellings. Holiday lighting: exempt, but 'dangerous glare' still barred.

An outdoor lighting plan missing the required shielding or illuminance certifications can be rejected at project review, and an installed fixture found casting glare or direct illumination onto a neighboring property is a zoning code-compliance violation that Development Services or Code Compliance can order retrofitted or removed, including as a condition tied to the certificate of occupancy.

The Bottom Line

Provo's outdoor lighting rules are a mixed bag. Some areas are strict, others are relaxed, and the details matter. The best approach is to check the specific rule that applies to your situation rather than assuming Provo is broadly strict or permissive.
