Outdoor Lighting in Frisco, TX: What Residents Actually Need to Know
If you live in Frisco or are thinking about moving there, outdoor lighting are one of those things you probably won't think about until they affect you directly. Frisco has 3 specific rules on the books covering different aspects of outdoor lighting, and some of them might surprise you.
Billboard Lighting
Every illuminated sign in Frisco, including electronic message boards, is capped at 750 candelas per square meter under Section 70-28, and external fixtures must be fully shielded. The luminance limit kicks in a half hour before sunset and stays in force through sunrise, using NOAA sunset and sunrise times.
Key details: Max luminance: 750 cd/m2 (Nits). Compliance window: half-hour before sunset through sunrise. External fixtures: must be fully shielded. Sunrise/sunset source: NOAA-determined times. Applies to: every illuminated sign, any zoning district.
A sign that exceeds the 750 cd/m2 luminance cap, uses an unshielded external fixture, or stays at daytime brightness after the half-hour-before-sunset compliance window begins violates Section 70-28 and is enforced under Chapter 70's general penalty scheme: a misdemeanor fine of up to $500 per day under Section 70-22, plus a possible civil penalty of up to $1,000 per day under Section 70-23 for a notified, continuing violation.
Dark Sky Rules
Frisco's Zoning Ordinance requires every outdoor light fixture on nonresidential property to be fully shielded so the bulb itself is never visible at three feet above grade on a lot line next to a home, or six feet elsewhere, and bans cobra-head style fixtures outright to protect the night sky and cut glare for drivers and neighbors.
Key details: Shielding height: 3 feet near homes, 6 feet elsewhere. Cobra-head fixtures: Prohibited outright under § 4.05.07(A). Pole height cap: 30 feet, 20 feet within 100 feet of homes. Cutoff angle: 90 degrees or less required. Governing law: Frisco Zoning Ordinance §§ 4.05.01, 4.05.02, 4.05.07.
A property owner who installs an unshielded fixture, a cobra-head lamp, or a pole taller than the height cap near a Protected Residential Property is out of compliance with Subsection 4.05, and the Chief Building Official can require a change-request submission and correction before a certificate of occupancy issues; a nonconforming lighting plan can also be denied or modified on review under § 4.05.06(C).
Light Trespass & Shielding
Frisco's Zoning Ordinance caps how much light can spill onto a neighbor's property: no more than one-quarter footcandle at a property line next to a Protected Residential Property, and one-half footcandle where the light spills toward a street right-of-way instead. The limit applies to every outdoor luminaire on private property, not just parking lot lights.
Key details: Limit near homes: 1/4 footcandle at the property line. Limit near streets: 1/2 footcandle at a right-of-way. Governing law: Frisco Zoning Ordinance § 4.05.02(D). Residential exemption: Fixtures 75 watts or less with cutoff. Measured at: The property line itself, not the fixture.
A luminaire that measures above one-quarter footcandle at a property line next to a Protected Residential Property, or above one-half footcandle at a street right-of-way, violates § 4.05.02(D); the Director can require the fixture be re-aimed, re-shielded, or replaced, and a noncompliant photometric plan can be rejected or modified under § 4.05.06 before a certificate of occupancy is granted.
The Bottom Line
Frisco'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 Frisco is broadly strict or permissive.
