Street Cleaning starts April 1 and ends November 30, dependent upon weather conditions. South Oakland days are typically the third Wednesday or Thursday. Check the signs in your area.
If there are a lot of parked cars being ticketed, it can greatly delay and ultimately prevent street cleaning. Please make sure to move your car and alert any neighbors as well.
