Snow & Ice Management in Evanston & Chicago's North Shore

Commercial property is not covered by the Illinois Snow and Ice Removal Act

The Illinois Snow and Ice Removal Act, 745 ILCS 75, shields residential owners, occupants and the people they hire from liability for injuries caused by the snowy or icy condition of an abutting sidewalk — even where the removal was done badly. The only exception is conduct that rises to wilful or wanton. That is a high bar, and it makes residential clearing a low-risk act.

Commercial property gets none of that. The Act is written for residential units, and commercial owners are left with the ordinary Illinois rules: generally no duty to remove a natural accumulation, but real exposure for an unnatural one. An unnatural accumulation is very often something the removal itself created — a snow pile stacked uphill of an entrance that melts across the walk by afternoon and refreezes after dark, a downspout discharging onto a cleared path, a low spot in a lot that nobody graded out.

Which is why where the snow goes matters as much as whether it moved. We stake and map piling locations before the season against the site's grades and drainage, and we keep them off entrances, accessible routes and anything that drains toward one. This is general information about how the rules work, not legal advice — your counsel and your insurer should see your actual contract.

The two-inch trigger, and what the village is doing while you wait

Most North Shore villages run their own operation on a two-inch trigger, and yours has to work around it. Wilmette begins plowing streets, business and school routes, cul-de-sacs and alleys after two inches, and imposes a village-wide parking ban once accumulation reaches two inches, holding for 24 hours after the snow stops or until operations finish, whichever comes first, under Village Code Chapter 13-8.10.1. Smaller events — under two inches, or sleet and freezing rain — trigger a one-side ban on streets 27 feet or narrower under Chapter 13-8.10.2.

Sidewalks are the gap people get wrong. Wilmette clears commuter and business routes first, targets completion by six to eight in the morning, moves to school routes, and only reaches residential sidewalks after four inches — within 48 to 72 hours of the storm ending. Your own walks, steps, entries and the path from the drive to the door are not in that queue at all. On a two-and-a-half inch event the village will have plowed your street and never touched a sidewalk.

We sequence our routes against those village schedules rather than against a clock, so a drive does not get cleared an hour before the municipal plow returns the berm to the apron.

Salt is the liability and the long-term damage, in that order

Over-application is the default failure in this trade, because more salt looks like more diligence. It is not. Rock salt stops working as temperatures drop, so a heavier spread on a cold night mostly produces runoff, and runoff in this region reaches the Lake Michigan watershed. The Salt Smart Collaborative, an Illinois programme for winter maintenance professionals, certifies contractors against calibrated spreading equipment, documented event records, annual staff training and yearly reporting.

There is a second cost that matters more to us than to a plow-only contractor: we built the hardscape. Chlorides spall concrete, work into the joints of a paver field, damage natural stone and kill the plantings along a drive edge — the same bluestone terrace and boxwood run somebody paid for two summers earlier. Product choice, application rate and where the meltwater goes are all design questions, and we treat them that way.

Winter contracts are written before the season

The seasonal window for signing is September through October. Route order is set before the first event, equipment and material are committed against the properties already under contract, and a property added in January is genuinely at the back of the queue. This is not a sales tactic. It is how the capacity works.

A scope worth signing names the trigger depth, the surfaces included — drive, walks, steps, entries, accessible routes — the response window, the ice management approach, where snow will be piled, when hauling becomes necessary, and what gets documented after each event. If a proposal does not say all of that, the parts it leaves out are the parts that get argued about in February.
