424 Hayes St, San Francisco, CA 94102

The two-story, three-unit multi-family residential building at 424 Hayes Street, owned by Phethsaya Lieng & Vieng, was constructed in 1916 and has undergone several significant renovations and faced multiple safety concerns in recent years. Most notably, there have been recurring issues with the fire safety systems, with violations documented in late 2024 including problems with standpipe systems and sprinkler systems, as well as multiple alarm system violations between 2023-2024 that were marked as corrected or resulted in violations. The building received substantial improvements in 2013-2014, including substantial electrical upgrades, HVAC installations, and tenant improvements, particularly during the conversion of a former grocery space to retail use that cost approximately $130,000.

The property has experienced several infrastructure and safety-related incidents over the years, including a 2012 egress obstruction issue involving blocked rear stairways, and multiple 2024 complaints regarding garbage and debris in the vicinity of the building, though these were generally resolved promptly. The building's address has been clarified through permit #M1007288 in 2018, establishing designations for 424A, 424B Hayes Street, and 323 Ivy Street for commercial use. Recent activity includes multiple 311 calls in late 2024 regarding street cleaning needs, particularly for garbage and debris, and a noise complaint in January 2025 that remains open.

The most serious recent issues involve the fire safety systems, with the most recent violation regarding standpipe systems and missing caps logged in December 2024, while a previously corrected alarm system violation from October 2024 was noted for being improperly maintained. There is a notable historical complaint from 2000 regarding an illegal freezing unit, and while there have been numerous building permits issued over the years, most have been related to routine maintenance and upgrades rather than major structural changes. The building's maintenance history shows regular upkeep of systems and infrastructure, though the recurring fire safety violations indicate an area of ongoing concern that has required multiple corrections and resulted in recent citations. The property has been the subject of multiple permit applications for various improvements, including significant electrical work, HVAC installations, and plumbing upgrades, particularly during the 2013 renovation period.
