1640 Bay St, San Francisco, CA 94123

1640 Bay Street is a 17-unit, 3-story multi-family residential building constructed in 1956, currently owned by Mehan Properties LLC. The building has undergone several significant safety improvements, including a completed soft-story retrofit in 2016 at a cost of $178,000, which required to comply with seismic safety regulations. Most recently, in 2024, the building upgraded its fire alarm system to meet current fire code requirements, with the work now complete at a cost of $41,800.

The building has experienced multiple fire safety-related issues over the years, with violations recorded for sleeping area requirements (December 2023), alarm system maintenance (March 2019), and several fire alarm system and fire escape concerns between 2015 and 2023 - though most of these were corrected promptly. The property has faced compliance challenges regarding its boiler systems, with multiple violations recorded between 2005 and 2024 for operating permits - though these were ultimately abated. In terms of emergency responses, there have been several false alarms and non-fire related incidents recorded between 2015 and 2023, including one intentional building fire (date unspecified) with no civilian injuries reported.

The building's maintenance history shows attention to major infrastructure elements, including reroofing work completed in both 1996 and 2003. Recent activity around the property (2024) has included multiple parking enforcement calls, primarily for blocked driveways, and some minor sanitation issues, though these do not appear to directly affect building safety. The building's documented history shows a reasonable pattern of addressing safety and compliance issues, though the recurring nature of some violations suggests ongoing monitoring of building systems and code compliance requirements.
