Sugar Land, TX Outdoor Lighting: Light Trespass & Shielding (2026)

Article XII of Chapter 2 regulates light trespass from any luminaire installed on non-single-family premises after February 9, 2010 (Sec. 2-351(A)). Section 2-352(B) makes it unlawful to operate a luminaire on a nonresidential or multi-family premises with a maximum vertical illuminance exceeding 2 footcandles on an adjacent premises zoned R-1E, R-1R, R-1, HR-1, R-1Z, MUC, R-3, or R-4, or on the residential portion of a Planned Development District, with the reading taken 10 feet inside the adjacent property. 5-footcandle ceiling where the adjacent property is zoned R-4, B-O, B-1, B-2, MUC, M-1, or M-2, or is used for commercial or industrial purposes in a Planned Development District, measured at the property line along a street right-of-way; that limit does not apply where a light spills across two adjoining lots that share the same zoning classification.

Vertical illuminance itself is defined at Sec. 2-350 as the reading taken by a light meter held vertically 5 feet above the ground and facing the light source, which keeps the standard objective rather than a matter of visual judgment. Several light sources are carved out of Article XII entirely under Sec. 2-351(B), including decorative holiday lighting, required airport lighting, hazard lighting, temporary emergency and construction-site lighting, fixtures emitting under 1,800 lumens, event-only entertainment lighting, architectural lighting aimed at building features, historic-landmark lighting, flag lighting, and public street lights. The Development Application Handbook sets the required content of the lighting plan submitted to demonstrate compliance with the footcandle limits (Sec. 2-352(D)).
