1660-1662 Sacramento St, San Francisco, CA 94109

The 12-unit, 3-story multi-family residential building at 1660-1662 Sacramento Street in Nob Hill, constructed in 1910, has undergone several significant safety improvements and renovations in recent years. Most notably, the building completed its mandatory soft-story retrofit in 2021 (Tier 3, with Certificate of Final Completion issued), and received a comprehensive fire safety system upgrade in 2021 including new control panels, smoke detectors, and low-frequency sounders. A concerning issue emerged in 2021 when tenants reported inadequate heating system functioning, with temperatures averaging between 63-66 degrees.

The building underwent important infrastructure upgrades including reroofing in 2018 (cost: $50,000), a steam boiler replacement in 2019, and a $120,000 fire alarm system upgrade in 2021. Multiple fire safety violations were recorded from 2009-2024 related to alarm systems, with the most recent violation in July 2024 concerning alarm system maintenance that was subsequently abated. The property has a history of various maintenance and safety compliance issues, with the most significant being the attempted ground floor unit addition in 2017 (estimated cost $450,000, canceled) and subsequent legalization efforts.

Historical complaints include concerns about windows, drainage, electrical systems, and pest control, though all these issues were ultimately resolved or abated. The building's fire safety systems have required ongoing attention, with multiple complaints and violations related to alarm systems between 2009 and 2024, though recent maintenance appears to have improved compliance. Recent 311 calls from 2024 primarily concern street-level debris and encampments, suggesting potential neighborhood maintenance challenges, though these are not directly related to the building's condition.
