Chicago’s sidewalk snow rule, by the numbers
Snow that falls between 7 p.m. and 7 a.m. has to be off the sidewalk by 10 a.m. Snow that falls from 7 a.m. until 7 p.m. has to be off by 10 p.m. That’s every day of the week, weekends included.
The cleared path has to be at least 5 feet wide on every sidewalk next to the property, including the crosswalk ramps at a corner. Fines run $50 to $500 per case, and an Administrative Hearings judge sets the amount, so the flat $50 you sometimes hear isn’t the whole story. The rules live in the Municipal Code, sections 4-4-310 and 10-8-180.
How often does it come up? O’Hare averages about 36.7 inches of snow a year, and about 11 days from December through March with an inch or more (1981–2010 normals). Evanston and Oak Park set their own rules, so check your city or village before counting on Chicago’s times there.
