St. Louis does not have comprehensive dark-sky lighting ordinance. General nuisance and zoning provisions address light trespass. New commercial development often required to use shielded full-cutoff fixtures through site plan review.
St. Louis has not adopted a formal dark-sky ordinance like Flagstaff or other designated dark-sky communities. Urban sky glow from the metropolitan area is significant. However, Title XXVI Zoning Code site plan review for commercial and multifamily projects commonly requires downward-shielded lighting and limits on light spillover across property lines. Industry standards referenced include IES (Illuminating Engineering Society) cutoff classifications. General nuisance provisions under Revised Code Chapter 11 allow complaints for unreasonable light intrusion. Parks Department and historic district reviews may require compatible fixture designs. Forest Park and the Central West End have upgraded many streetlights to LED fixtures with cutoff optics.
Nuisance lighting: notice to abate, $100-$500 fine if not corrected. Site plan noncompliance: reviewed at certificate of occupancy.
