Dark Sky Rules
Lewisville does not have a standalone dark sky ordinance, but outdoor lighting is regulated through zoning standards in the Unified Development Code Chapter 114. Commercial and multifamily developments must use full-cutoff fixtures that direct light downward and minimize upward emission, with light levels at property lines adjacent to residential zones limited to 0.5 foot-candles. Residential exterior lighting is largely unregulated beyond general nuisance provisions in Chapter 42. The city does not mandate International Dark Sky Association-compliant fixtures or enforce specific color temperature limits. HOA communities such as Castle Hills and Valley Vista may regulate exterior lighting through their architectural review standards.
