The San Francisco Police Department is still deciding exactly how it will enforce the law.
The ban was approved by voters in November and mandates that police give out citations to violators only after the person has been warned at least once. However, the department is still figuring out how to track those warnings.
Officers do have the discretion to issue additional warnings after the first one. Once a citation is issued, the maximum penalty is a $500 fine and 30 days in jail. Police hope to start enforcing the sit-lie ordinance by the end of the month.
