Skokie, IL Outdoor Lighting: Dark Sky Rules (2026)

Skokie has not adopted the International Dark-Sky Association model ordinance but the zoning code and property maintenance code include provisions limiting glare and light trespass. Commercial and multi-family zoning districts require exterior lighting to be shielded and directed downward to prevent light spillage onto adjoining residential properties and public right-of-way. Maximum illuminance at residential property lines is typically capped at 0.5 foot-candles. Site plan review for new commercial development evaluates lighting plans. Residential properties are subject to fewer regulations, but outdoor lighting that creates a nuisance (excessive brightness shining into neighbors' windows, all-night unshielded floodlights) may be cited under the property maintenance code's general nuisance provisions. Skokie's dense suburban environment with street lighting means truly dark skies are not achievable, but careful lighting design can reduce light pollution and protect neighbors. Holiday lighting is generally excluded from regulation as a seasonal, temporary display.
