Technically you’re not supposed to be parked on the street at any time during the street sweeping time window. However if the street sweeper has passed AS WELL AS THE PARKING ENFORCEMENT OFFICER, the chance is low that the enforcement officer will come down the street a second time to give you a ticket. Some cities DO allow you to park after the sweeper has passed but it's rare so make sure you know the rules for your city so you don't get a ticket. That’s not legal advice so park at your own risk.
