Chicago FAQ
Do paper sale signs count toward the limit?
Yes. All window signage including paper, vinyl, painted, and electronic signs counts toward the coverage limit set in MCC 17-12. Temporary holiday and sale signs are still subject to time limits.
Can I put neon in my front window?
Neon is allowed with a sign permit and must meet brightness and percentage-of-window limits. Pedestrian street overlays may further restrict illuminated window signs facing the public sidewalk.
Oak Lawn FAQ
Do I need a permit for a window sign in suburban Cook?
Permanent window signs usually need a sign permit from the municipal building department; many suburbs exempt temporary or seasonal signs under 30 days. Check your village or city code before installing painted or vinyl applied signage.
What counts toward the percentage limit?
Most codes count any opaque or translucent signage, including vinyl lettering, neon, LED open signs, and posters visible through glass. Clear glass area used for visibility into the store generally is excluded from the calculation.
Can I cover my entire storefront window during a sale?
Generally no. Even temporary sale banners count toward window coverage limits in most Cook suburbs. Some allow short-term coverage for grand openings or going-out-of-business sales with a temporary permit and time limits.
