1643 Mason St, San Francisco, CA 94133

The two-unit residential building at 1643 Mason Street in Russian Hill, owned by Leo Cynthia, is a 2-story flats and duplex structure built in 1907. The property has experienced significant activity over the past year related to parking and public safety issues.

Between July and December 2024, there were multiple incidents of driveway blocking, with seven reports to parking enforcement, three of which resulted in citations, though most officers were unable to locate the offending vehicles. Additionally, there were two reports of encampments on/near the property in August 2024, one of which was resolved while the other could not be located.

A garbage and debris issue involving furniture was reported and resolved in July 2024. Looking further back in the building's history, there was a minor fire incident recorded from July 2008 involving smoke from a barbecue or tar kettle, which resulted in no civilian injuries, and a weed and grass complaint in the same year that was found to have no merit. The concentration of parking-related complaints in 2024, particularly those involving driveway blocking, suggests ongoing challenges with street parking in the immediate vicinity, though it's worth noting that enforcement officers were often unable to locate the offending vehicles.
