275-277 Oak St, San Francisco, CA 94102

The 275-277 Oak Street property is a two-unit, two-story multi-family residential building located in Hayes Valley, constructed in 1900 and currently owned by Nobuth Prithvi & Patel Kirt. The most significant recent development occurred between 2018-2020 when the building underwent major improvements including the addition of two ADU units in the ground floor garage and storage area, installation of a complete sprinkler system, and substantial plumbing and electrical upgrades.

The project included voluntary seismic improvements and was completed with a total investment of approximately $190,550. More recent maintenance and compliance work has been conducted in 2020, including furnace replacements, water heater installations, and electrical upgrades, with the most recent building inspection-related work completed in late 2020 to comply with inspection report CC-8465. The building's history reveals several maintenance and safety concerns, with the most serious being an active housing complaint from 1995 regarding a bathroom ceiling collapse with potential electrical concerns, as well as multiple plumbing-related issues in 2005 involving sewer concerns that were promptly addressed.

The property has had some fire safety incidents, including two false alarms in 2021 and a sprinkler system issue that was corrected in July 2021. Recent records from 2025 show multiple reports of garbage and debris issues near the property, though these are street-related matters and not directly concerning the building itself. The property's infrastructure upgrades, including the 2018-2020 sprinkler installation and ADU additions, suggest significant investment in improving the building's safety and living conditions, though ongoing maintenance issues like the 1995 ceiling collapse complaint and recent street cleaning needs indicate that some areas still require attention.
