640 Post St, San Francisco, CA 94109

The 39-unit, 9-story multi-family residential building at 640 Post Street, owned by the Harry H III Trust, has experienced significant and ongoing maintenance and safety issues since its construction in 1912. Most recently, in the first half of 2024, there have been multiple complaints regarding inadequate hot water supply, low water pressure, and unauthorized plumbing work, with residents reporting persistent discomfort in cold weather. Three plumbing complaints were filed in March 2024 regarding inoperative plumbing, affecting multiple units.

The building has a concerning history of fire safety violations, with multiple citations issued between 2015 and 2024, including recent violations in December 2024 related to sprinkler systems and sleeping area requirements. There have also been significant plumbing infrastructure updates, including the removal and replacement of domestic hot water storage tanks in March 2024, and the installation of a new heating boiler in 2011. The building's maintenance record shows a pattern of deferred upkeep and emergency repairs, with residents reporting unpermitted work, construction outside of posted hours, and various system failures. A cluster of complaints in December 2022 highlighted multiple urgent issues, including gas leaks, plumbing problems, and concerns about an alleged illegal unit on the rooftop.

The property has also faced historical violations regarding its sprinkler system, electrical work, and window safety features. Recent 311 calls from January 2025 indicate continued concern about building management responsiveness, though these were primarily related to housing inventory requests. The fire department's records show regular inspections and occasional incidents, though none involving civilian injuries. The building's age and history suggest ongoing maintenance challenges, with recent complaints focusing on basic services like hot water and heating being particularly prominent through 2023-2024.
