Round Rock, TX Outdoor Lighting: Light Trespass & Shielding (2026)

Section 8-1(b)(4) of Round Rock's Unified Development Code governs outdoor lighting on nonresidential and multifamily sites. Every light source must be completely concealed within an opaque fixture housing, invisible from the street or from any residential property line. Illumination is capped at one foot-candle at a shared nonresidential property line, two foot-candles along a public street, and just 0.5 foot-candles where a lot borders a residential property. City staff reviewing the site plan can require additional exterior shielding or other light-mitigation measures whenever they judge the standard fixture cutoff insufficient to protect neighboring homes.
