1447 Chestnut St, San Francisco, CA 94123

The three-story, 12-unit multi-family residential building at 1447 Chestnut Street in the Marina, built in 1926, has undergone several significant safety and maintenance improvements over the years, with the most recent being a comprehensive fire alarm system upgrade completed in October 2024, costing approximately $35,800. The building has successfully completed its mandatory soft-story retrofit as a Tier 3 property, demonstrating compliance with seismic safety requirements. Major improvements include a 2017 soft-story retrofit costing $105,000, 2016 stair repairs following a violation notice, and electrical system upgrades in 2003 to 175-amp service with 13-meter sockets.

The property underwent routine safety inspections in 1999, 2006, and 2016, addressing various issues including gate manual release systems and carbon monoxide alarm installations, all of which were subsequently resolved. Recent building activities have primarily focused on life safety systems, with the most substantial work being the 2024 fire alarm system upgrade that included new low-frequency sounders in sleeping areas to meet current codes. The building had documented fire safety concerns in 2018 regarding hazardous materials and sprinkler systems, though these violations were abated as of May 2018.

Regular maintenance has been performed throughout the building's history, including termite repairs in 1995, window and bathroom improvements in the late 1980s, and various routine inspections. The property has experienced recurring issues with driveway blockage, as evidenced by multiple parking enforcement calls in recent years, though these are external to the building's internal systems and safety features. Recent service requests have primarily involved waste collection and public works matters, which have all been resolved promptly.
