219-221 Liberty St, San Francisco, CA 94114

The two-unit, two-story multi-family residential building at 219-221 Liberty Street, owned by the Marvin Rous Trust, was constructed in 1890 and has undergone several significant infrastructure improvements over the years, including a documented building permit from 1982 and an electrical service upgrade in 2003 that converted the underground service to 100 amps with two meters.

The property has experienced recurring sewer-related issues between 2016 and 2018, with multiple incidents involving sewage backup, flooding, and infrastructure maintenance requests, though these have all been officially resolved according to PUC records. More recently, the building's location has faced intermittent challenges with parking enforcement, particularly regarding driveway blocking incidents, with five documented cases between 2020 and 2024 involving various vehicles, all of which were resolved through citations or officer response.

While these driveway access issues are noteworthy, they primarily affect street access rather than the building infrastructure itself. The most recent incident on record was a parking violation in January 2024, suggesting that while the building's critical systems have been stable in recent years, street-level access remains a periodic concern for residents.
