Outdoor Lighting in Norman, OK

Norman maintains 134 local ordinances across all categories, and 3 of those deal specifically with outdoor lighting. Here is a breakdown of what the city actually requires, what is prohibited, and where Norman falls on the strict-to-permissive spectrum compared to other cities.

Dark Sky Rules

Since July 22, 2011, every new commercial, industrial, institutional, or multifamily development in Norman must use full cut-off outdoor light fixtures mounted horizontally so no light escapes upward, under NCC 36-549. Single-family and two-family residential lighting is exempt, as are athletic fields, holiday lights, and interior courtyard fixtures.

Key details: Fixture standard: full cut-off, mounted horizontally to the ground. Effective date: permits issued after July 22, 2011. Applies to: commercial, industrial, institutional, multifamily only. Exempt: single-family and two-family residential lighting. Prohibited citywide: laser advertising light and searchlights.

A confirmed lighting violation first triggers a compliance order requiring shielding, re-aiming, or replacement with a full cut-off fixture rather than an automatic fine. Ignoring that order becomes a Chapter 36 violation punishable under NCC 36-569 by a fine of $50 to $750 per day, with each day counted as a separate offense.

Billboard Lighting

Norman's off-premises sign standards, NCC 28-601, ban billboard lighting that glares into traffic or obscures a traffic signal. Digital billboards face their own brightness ceiling: no more than 300 NITs after dark, rising to 500 NITs if the site abuts a lit commercial or industrial property, and up to 5,000 NITs during the day, with each message held at least eight seconds.

Key details: Governing section: NCC 28-601, off-premises sign standards. Glare rule: No beams directed at travel lanes. Night brightness cap: 300 NITs, up to 500 near lit sites. Day brightness cap: 5,000 NITs. Message dwell time: At least 8 seconds per message.

A billboard that glares into traffic, obscures a signal, or exceeds the 300/5,000-NIT brightness schedule violates NCC 28-601 and is subject to citation by the Code Compliance Officer under chapter 28's enforcement provisions, with each 24-hour period of a continuing violation a separate offense. Chapter 28 sets no specific dollar fine for this section, so the Code's general penalty in NCC 1-114 applies: up to $750.00 or 60 days imprisonment, or both, and the City may also seek a court order to abate the violation.

Light Trespass & Shielding

NCC 36-549 caps light spilling onto neighboring single- or two-family property at 0.2 footcandles measured at the property line, with permanent shielding required on pole-mounted fixtures to keep it that way. Light poles within 25 feet of a residential line are also capped at 20 feet tall.

Key details: Max spillover: 0.2 footcandles at a residential property line. Measured: any point on the line, adjacent or across the street. Pole height near homes: 20 ft max within 25 ft of residential line. Pole height elsewhere: 30 ft max. Shielding: must be permanently installed.

Once a Code Enforcement or Police Officer measures light spillover above 0.2 footcandles at a residential property line, the fixture's owner must shield, re-aim, or replace it with a full cut-off fixture; refusing is enforced under NCC 36-569 with fines of $50 to $750 per day of continued noncompliance.

The Bottom Line

Norman'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 Norman is broadly strict or permissive.
