"Parking is generally prohibited on all streets from 2:30 - 6 a.m., seven days per week, year around, except when allowed by permit or pass. The overnight parking restriction dates back to the late 1920s. Overnight on-street parking of cars bearing permits is only allowed in multifamily housing areas, except in front of churches, schools and parks and on blocks where housing is more than 50 percent single family.In areas of Oak Park not zoned for multi-unit buildings or designated as permit areas, the overnight parking ban remains fully in effect."
It's a little strange going down a dense Oak Park block of homes at night that looks like a Chicago street but with no cars parked anywhere. Few cars are parked on the streets during the day as well. When guests need to park overnight, you must call the car in to the Village.
