Tulsa's Outdoor Lighting: The Rules That Matter
Every city handles outdoor lighting a little differently. In Tulsa, Oklahoma, there are 3 distinct rules that residents and property owners should be aware of. Some are stricter than what neighboring cities enforce, and others are more relaxed. Here is what you need to know.
Billboard Lighting
Tulsa caps illumination on off-premise billboards at 70 foot-candles measured at the sign face, requires constant (non-flashing) light, and bans blinking, traveling lights or reflective glitter under the city's zoning code.
Key details: Max illumination: 70 foot-candles at sign face. Light type required: Constant light only, no flashing. Digital billboard cap (day): 6,500 nits maximum. Digital billboard cap (night): 500 nits, dusk to dawn. Governing code: Tulsa Zoning Code § 60.080.F.9.
Signs need a permit under Title 51 before installation; unpermitted, over-bright, or flashing off-premise advertising signs are zoning violations enforced by the city's development administrator, who can deny, condition, or revoke a sign permit for noncompliance.
Dark Sky Rules
Tulsa's zoning code requires outdoor fixtures installed since 2016 to be shielded with cutoffs limiting glare, caps light spillover onto neighboring lots at 0.5 to 3.0 foot-candles, and sets maximum fixture heights up to 35 feet based on distance from residential land.
Key details: Effective date: January 1, 2016. Shielding cutoff: 2.5% light above 90° nadir. Spillover cap: 0.5–3.0 foot-candles at lot line. Max fixture height: 16–35 ft by distance. Max penalty: $1,200 fine, 6 months jail.
Violating any zoning code provision, including Chapter 67's lighting standards, is a misdemeanor punishable by up to a $1,200 fine and six months in jail; the development administrator can also withhold permits or issue stop-work orders (Section 85.040.A).
Light Trespass & Shielding
Tulsa caps spillover light at the property line to 0.5 foot-candles next to homes and 3.0 foot-candles elsewhere, measured under the zoning code's outdoor lighting standards.
Key details: Residential-abutting limit: 0.5 foot-candles at lot line. Non-residential-abutting limit: 3.0 foot-candles at lot line. Measurement height: 3 feet above grade. Effective date: January 1, 2016. Exempt fixtures: Under 1,000 lumens.
Enforced through the site plan and lighting plan review process administered by Tulsa's Development Services; noncompliant lighting can hold up site plan approval, and existing installations exceeding the foot-candle caps or lacking required shielding are subject to code enforcement action under the Zoning Code.
The Bottom Line
Tulsa'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 Tulsa is broadly strict or permissive.
