Evanston's Outdoor Lighting: The Rules That Matter

Every city handles outdoor lighting a little differently. In Evanston, Illinois, there are 3 distinct rules that residents and property owners should be aware of. Some are stricter than what neighboring cities enforce, and others are more relaxed. Here is what you need to know.

Billboard Lighting

Illuminated signs in Evanston, including any billboard-type structure, cannot exceed 75 foot-candles of brightness, dropping to 50 in residential zoning districts and 1 on adjoining residential property.

Key details: General brightness cap: 75 foot-candles. Residential-district cap: 50 foot-candles. Spillover onto neighbors: 1 foot-candle maximum. Governing section: Evanston City Code § 6-19-7(M)(5).

A sign that measures above the foot-candle ceiling for its zoning district, or that spills more than 1 foot-candle onto neighboring residential land, violates Evanston's illumination standard.

Dark Sky Rules

Evanston caps outdoor lighting at half a foot-candle measured at the property line. Section 402.4 of the 2021 International Property Maintenance Code, adopted and enforced as Evanston City Code Section 5-1-3, bars exterior lighting that causes light trespass or glare onto neighboring properties and the public way, with narrow exceptions for motion-activated security lights and holiday lighting.

Key details: Limit: 0.5 foot-candle at the property line. Source code: 2021 IPMC § 402.4, adopted at § 5-1-3. Security lighting exception: Motion-activated, off within 5 minutes. Holiday lighting: Governed by NFPA 70 instead. Enforcer: Building & Development Services Code Official.

A property owner who ignores a notice of violation is guilty of a strict-liability offense under Section 109.3 and faces escalating fines set by Section 109.4: $150 for a first violation, $400 for a second, and $750 for a third or later violation, with each day the excess lighting continues counted as a separate offense. The Code Official can also pursue a court action to restrain or correct the violation, and unresolved fines become a lien against the real estate.

Light Trespass & Shielding

Evanston caps exterior lighting at one-half foot-candle measured at the property line, barring glare and light trespass onto neighboring properties and public ways.

Key details: Property-line limit: 0.5 foot-candle. Security lighting: must be motion-activated. Security light shutoff: within 5 minutes. First-offense fine: $150.

First offense $150, second $400, third and later $750, with each day a violation continues after notice counted as a separate offense.

The Bottom Line

Evanston's outdoor lighting rules are a mixed bag. Some areas are strict, others are relaxed, and the details matter. The best approach is to check the specific rule that applies to your situation rather than assuming Evanston is broadly strict or permissive.

These rules come from Evanston's publicly available municipal code. For complete penalty schedules, exemption details, and answers to common questions, see the individual ordinance pages throughout this guide.
