Outdoor Lighting in Irving, TX

If you live in Irving or are thinking about moving there, outdoor lighting are one of those things you probably won't think about until they affect you directly. Irving has 3 specific rules on the books covering different aspects of outdoor lighting, and some of them might surprise you.

Light Trespass & Shielding

In Irving's State Highway 161 overlay district, exterior lighting cannot cast glare onto neighboring lots or streets and cannot add more than one footcandle of light at any point off the property. Building-mounted fixtures are also height-capped so spillover stays close to the ground and off adjacent land.

Key details: Maximum spillover: 1.0 footcandle at any off-site point. Applies to: State Highway 161 overlay district only. Fixture height: 10 to 18 feet above grade for wall-mounted lights. Max fine: $2,000 per day, Code § 1-6. Grandfather date: March 22, 2012 for existing structures.

Exceeding the one-footcandle spillover limit or casting glare onto a neighboring lot is a zoning violation under Code of Civil and Criminal Ordinances § 1-6, punishable by a fine up to $2,000 because it arises under the zoning ordinance rather than the general $500 cap, with each day the condition continues counted as a separate offense. Irving's Building Official checks lighting plans against these limits during site plan and permit review before construction in the overlay proceeds.

Billboard Lighting

Irving's digital-billboard permit rules under Section 7-4.2(b) set hard limits on how a converted freeway billboard can display and light its image: no flashing, intermittent, or moving lights, no animated video or scrolling text, and the display must automatically dim or brighten to match natural ambient light conditions before city council will approve it.

Key details: No flashing/animation: Static image required, § 7-4.2(b)(2). Dimming requirement: Auto-adjusts brightness to ambient light. Message hold time: Minimum 8 seconds per message. Message change speed: 2 seconds or less, whole face at once. Malfunction response: Owner must respond within 1 hour.

A digital billboard that flashes, scrolls, animates, or fails to dim automatically to ambient light violates the Section 7-4.2(b) performance standards and can have its special sign permit suspended or revoked by the director; noncompliant conversions are also subject to the Section 7-22 penalty of one to five hundred dollars per day the violation continues.

Dark Sky Rules

New development in Irving's State Highway 161 overlay district must shield every outdoor fixture with skirts or cutoffs capped at a 90-degree angle so glare stays off neighboring property. Cobra-head fixtures, galvanized poles, and light arms over four feet are banned, and non-security lighting must dim or shut off after business hours.

Key details: Cutoff angle limit: 90 degrees maximum on shielded fixtures. Applies to: State Highway 161 overlay district only. Banned fixtures: Cobra head, galvanized poles, arms over 4 ft. Color standard: Minimum 2,800 Kelvin white light. Max fine: $2,000 per day, Code § 1-6.

Lighting that isn't shielded, or that uses a banned fixture style, is a zoning violation under Code of Civil and Criminal Ordinances § 1-6: since it arises under the zoning ordinance, it carries a fine up to $2,000 rather than the general $500 cap, and each day the noncompliant fixture stays up counts as a separate offense. Irving's Building Official reviews lighting plans during site plan and permit review before construction proceeds in the overlay.

The Bottom Line

Irving'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 Irving is broadly strict or permissive.

These rules come from Irving's publicly available municipal code. For complete penalty schedules, exemption details, and answers to common questions, see the individual ordinance pages throughout this guide.
