Summary

Aurora's Unified Development Ordinance requires all sign illumination, including off-premises billboards, to be shielded against glare onto neighboring land, and bars lighting billboards next to residential property between 11 p.m. and 6 a.m.

3. Illumination. Illumination shall be shielded so there is no glare in the public right-of-way and adjacent properties, and directed so light does not stray above the light source horizontally. All lighting elements shall be kept in working condition.

Full Breakdown

Two UDO provisions govern billboard lighting in Aurora. Section 146-4.10.15(E)(3) requires all sign illumination, including off-premises signs/billboards, which are permitted only in the I-2 district within 1,000 feet of a highway, to be shielded so there is no glare onto the public right-of-way or adjacent properties, with light directed so it doesn't stray above the light source horizontally. Section 146-4.10.13(A)(5) separately requires any off-premises sign abutting a residential use or district to go dark between 11:00 p.m. and 6:00 a.m. A billboard visible from a residential zone district or a freeway/interstate isn't allowed at all under § 146-4.10.13(C). Billboards along state highways may also need a separate Colorado Department of Transportation outdoor-advertising permit; the UDO governs only local siting and illumination.

Violations & Fines

An unshielded or non-curfewed billboard light is a UDO violation. The City typically gives 10 days' written notice to correct it, then may summon the owner to municipal court, with penalties set under Aurora City Code § 1-13 and each day of continued violation counted separately.

Frequently Asked Questions

Do billboards near homes have to turn their lights off at night?
