649 Bay St, San Francisco, CA 94133

This three-story, six-unit multi-family residential building located at 649 Bay Street in Russian Hill was built in 1962 and has undergone several significant improvements over the years. The most substantial recent work was a completed seismic soft-story upgrade in 2017 costing $95,000, which brought the building into compliance with important safety standards.

Regular maintenance has been demonstrated through various building permits, including reroofing work in 2008 and 1991, and street space permits in 2010 and 2017. The building has experienced several infrastructure issues recently, particularly with sewer systems, as evidenced by four sewage backup incidents between October 2023 and January 2024 involving the 4-inch sewer vent. There were also two sidewalk-related issues reported in April 2023, though inspections found no problems.

Historical records show a cluster of violations in 2006 related to fire safety and gas utility systems, including malfunctioning emergency exit lights, fire door issues, and gas meter requirements, though all these violations were promptly addressed and abated by July 2006. The building has maintained regular housing inspections (2000, 2004, 2006, and 2008), indicating ongoing oversight by housing authorities. While there have been miscellaneous issues reported through 311 calls, such as graffiti, illegal postings, and human/animal waste on the street, these appear to be more related to the building's urban environment rather than structural or maintenance concerns.
