645 Bush St, San Francisco, CA 94108

The Angelus Apartments, a 52-unit multi-family residential building located at 645 Bush Street in the Union Square neighborhood, is a 5-story structure built in 1911 currently owned by Angelus Apartments LP. The building has undergone several significant safety upgrades in recent years, with the most recent major works including a fire alarm system upgrade in 2024 costing over $105,000 to comply with fire code requirements, and the installation of low-frequency sounders in sleeping areas to meet current safety standards. The property has a history of addressing fundamental safety concerns, including seismic upgrading in 1993 and the installation of fire sprinklers in 2007.

Recent inspections and fire complaints have revealed ongoing safety and maintenance issues, particularly concerning fire safety systems. Multiple fire code violations were noted in 2024, including blocked exits and sprinkler system problems, though some violations were promptly corrected. The building experienced significant maintenance challenges in 2007, including plumbing issues, interior damage, and ventilation problems.

Historical building violations from 2000 included various safety concerns such as egress obstruction and fire extinguisher accessibility, all of which were subsequently abated. The property has also undergone several infrastructure improvements over the years, including electrical upgrades, plumbing improvements, and the replacement of circuit breaker load centers in 2012. While the building's management has generally addressed violations and performed necessary maintenance, the frequency of recent fire-related violations and complaints suggests ongoing challenges with maintaining current safety standards and systems.
