Cook County and most suburban municipalities exempt seasonal decorative holiday lighting from outdoor lighting and sign restrictions during a typical November 1 through January 15 window. Outside that period, decorative lights revert to standard light trespass and zoning sign rules.
Cook County zoning Ch. 102 and analogous suburban Cook municipal codes carve out seasonal exceptions for holiday and decorative lighting. The standard pattern allows residential and commercial properties to install temporary decorative lighting from approximately November 1 through January 15 without regard to color temperature, shielding, or sign-area limits, provided the lights do not create a traffic hazard or substantial light trespass. Outside the exemption window, the same lighting is treated as ordinary outdoor lighting subject to shielding rules or as a display subject to sign-area limits. Some suburbs extend the window for cultural and religious observances. Many HOAs impose stricter take-down dates enforced under covenants rather than county code.
Leaving holiday lighting installed past the seasonal exemption window can be cited as a sign-code or property-maintenance violation. Code enforcement typically issues a courtesy notice first; refusal to remove out-of-season decorations triggers administrative fines under municipal property maintenance ordinances.
