400 Liberty St, San Francisco, CA 94114

The 4-unit, 2-story multi-family residential building at 400 Liberty Street, owned by Blue Circle LLC, was constructed in 1949 and has undergone several significant maintenance and compliance updates over the years. Most recently, in October 2024, the building received a substantial reroofing project costing over $22,000, which involved the installation of a 3-ply modified bitumen system. Other notable recent infrastructure work includes the installation of a new building sewer with house trap in 2017, and a canceled plumbing permit in December 2023 for house trap replacement.

The building has a history of addressing safety and maintenance concerns, particularly evident in a cluster of violations and complaints from 2000-2006, which were all successfully abated by September 2006. These included issues with fire safety (requiring fire extinguisher recharge and combustible storage removal), security (self-closing exterior doors), and utility safety (gas meter instructions and shutoff tools). A 2008 complaint regarding a smoke alarm was resolved promptly.

The property has maintained regular upkeep, as shown by routine repairs such as a 2014 deck repair project and periodic reroofing work in 2012. Recent activity around the property (2023-2024) has primarily involved external matters such as garbage removal, street cleaning, and tree maintenance, with no active building violations or safety concerns currently outstanding. The building's systems have generally been kept up to date, with the most recent maintenance focusing on roofing and plumbing infrastructure.
