1721 Chestnut St, San Francisco, CA 94123

1721 Chestnut Street is a 12-unit, three-story multi-family residential building constructed in 1964, currently owned by Mehan Properties LLC. The building has undergone significant safety improvements in recent years, most notably completing mandatory soft-story retrofits in 2019 (with an additional revision) at a total cost of $115,000, achieving compliance with San Francisco's seismic safety requirements. The building's fire safety systems have received attention, with a new fire alarm system modification and low-frequency sounder installation currently in process (August 2024), though a recent fire violation was issued in January 2024 regarding alarm system maintenance.

The building has experienced several maintenance and safety issues over its history. In 2017, multiple violations were issued and subsequently abated regarding interior surfaces, water damage, lead paint concerns, and various safety systems including carbon monoxide detectors, fire escape maintenance, and smoke enclosure doors. A 2014 complaint about inadequate hot water service due to an undersized replacement water heater was documented.

More recently, the building has had visible maintenance issues including graffiti (2023) and a collapsed sidewalk (2023) nearby. The property has a history of plumbing and electrical work, with records showing water heater replacement in 2014 and the most recent gas line work completed in March 2024. While the building has faced various challenges, most violations and complaints have been resolved through appropriate corrective actions, and major safety systems are being actively maintained and updated.
