Every municipality in the county bans overnight street parking in winter. The hours start at 2 a.m. in all of them and end somewhere between 5 and 8, the season runs from three months to all year, and two villages change the rules the moment the snow reaches a set depth.
The parking rules are the municipalities’ own; the driveway the car moves onto is the part an independent local operator can be matched to clear. This site makes that match and plows nothing.

A row that says “not read” means the municipality’s page states the rule but the codified section was not served. The hours and fines are the municipality’s own.
Most snow emergencies have to be declared. Menomonee Falls’ does not. Village code § 106-154: “There is hereby declared an emergency to exist in the village by reason of a heavy snowstorm whenever snow falls to a depth of three inches or more.” It lasts 48 hours or until plowing is declared complete. There is no announcement to miss; the depth is the announcement. NOAA’s 1991–2020 normals for Waukesha count 4.7 days a season with three inches or more, so a Menomonee Falls resident should plan on about five automatic emergencies a winter.
Delafield’s trigger is an inch higher and works differently. Under § 48-5(d) the ordinary ban runs 2 to 6 a.m. from November 1 to May 1. When snowfall reaches “four inches or more in any 24-hour period,” two more windows close: no parking over 30 minutes from 7 p.m. to 2 a.m. and again from 6 to 9 a.m., and vehicles “are subject to being removed.” The effect is that on a four-inch day a car on a Delafield street has to be off it from 7 in the evening until 9 the next morning, with a half-hour grace.
The City of Waukesha’s rule is not seasonal: “No vehicle shall be parked on any public street within the City between the hours of 2 a.m. and 5 a.m., except with a night parking permit.” The permit is priced by the night, $6 for three nights up to $160 for a year, and it comes with an even-odd rule, permit holders parking “on even-numbered sides of the street on even days and odd-numbered sides of the street on odd days.” In a snow emergency the permit is worthless: “Permits are not valid during snow emergencies.” A Waukesha renter with a permit and no driveway has nowhere to put the car on the night that matters.
Brookfield’s § 10.08.030 bars street parking “between two a.m. and six a.m. of any day except with express permission of the police department,” and its § 10.08.120 adds a separate offense that applies at any hour: a vehicle “upon any uncleared street during or after a snowstorm so as to interfere with the operation of snow removal” is towed at the owner’s expense. The Town of Brookfield goes further in season, with no parking on town roads at all from November 1 through April 30.
Oconomowoc’s ban is the shortest, December 1 to March 1 from 2 to 5 a.m., with a $30 fine under Ord. 7.03(2). Hartland, Sussex, Mukwonago and Merton run November 1 through March 31, or November through March in Merton’s wording; Delafield runs to May 1. Hartland’s is the one with a published escalation: $25, rising to $50 after five days, a DOT registration suspension after 30, and a tow six hours after the notice is posted. Mukwonago and Merton allow 30 minutes, which covers a drop-off but not a night.
The Village of Pewaukee’s rule is built around the emergency rather than the calendar. Under § 86.117 twelve named streets are closed to parking “during a snow removal emergency during the hours of 10:00 p.m. to 7:00 a.m.,” and ordinary all-night parking from 2 to 6 a.m. needs a permit. The street list was not reproduced here; the village’s own code has it.
Where a row above is blank, the village either does not publish the rule online or its code host would not serve it. Elm Grove’s parking chapter and New Berlin’s were both unreachable; neither absence means there is no rule.
Say how many cars need to come off the street and which municipality sets the hours.
