Chicago Code Lighting Requirements
The City of Chicago maintains a building code that is distinct from the standard NFPA guidelines used in the rest of the country. To pass inspection, your Chicago exit sign must meet three critical visual standards:
- Red Letters Only: The word "EXIT" must be illuminated in Red. Green exit signs are strictly prohibited within city limits.
- 6-Inch Letter Height: The letters must be exactly 6 inches high with a 3/4-inch stroke (width), ensuring clear visibility.
- Arrow Placement: Unlike standard signs that use "pop-out" chevrons on the left and right, Chicago code lighting mandates that any directional arrows must be located below the word "EXIT" and cannot be removable stickers.
Steel Housing & Glass Panels
Beyond the lettering, the construction of the sign itself is regulated for durability and fire resistance.
- 20-Gauge Steel: The housing must be made of non-combustible material, typically 20-gauge steel in a white finish. Plastic or thermoplastic housings are generally prohibited.
- Translucent White Background: Unlike "stencil face" signs where the letters are cut out of a plastic frame, Chicago signs typically feature a translucent glass or high-grade acrylic panel. This creates a fully illuminated white background that diffuses light evenly, with the red letters and arrows screened or painted onto the face.
- Plenum Rating: If your sign is recessed into a ceiling used for air circulation, it must be Chicago Plenum Approved to ensure it meets air handling safety standards.
Chicago Emergency Lights & Combos
We also stock Chicago emergency lights that meet the city's requirement for metal components.
- Steel Heads: The lamp heads on emergency units must be constructed of metal, not plastic.
- High Wattage: Chicago code often requires higher wattage capacity to ensure brighter illumination of the egress path.
- Combo Units: Our Chicago exit signs are available as combination units, featuring the mandatory steel sign with attached metal emergency lights for a complete, code-compliant solution.
