About Sweep SF

Analzying over 1 million tickets to help you park legally and respectfully in SF (and avoid a $100 ticket!).
Our data utilization and mission.

Our Mission

This tool is designed to help San Francisco residents and visitors park legally and respectfully while avoiding parking tickets. By understanding when street sweeping occurs and when enforcement typically happens, you can make informed decisions about where and when to park.

Our goal is to promote responsible parking that respects street sweeping schedules, helping keep San Francisco's streets clean while reducing unnecessary parking citations.

3. Street Blocks

Source: City of San Francisco - Streets (Active and Retired) Dataset

This dataset provides accurate street geometry and address ranges, enabling precise address matching and side-of-street determination.

How It Works

This application combines official street sweeping schedules with historical parking ticket data to provide insights into:

  • When street sweeping is scheduled for your address and block
  • When tickets are typically issued based on historical enforcement data
  • How your side of the street is unique (East/West/North/South)
  • Time distributions showing when tickets are most commonly issued

By analyzing patterns in historical ticket data, we can help you understand when street sweeping is most likely to occur, allowing you to move your car or park accordingly.
