3149-3151 Harrison St, San Francisco, CA 94110

The two-unit residential building at 3149-3151 Harrison Street in Bernal Heights is a two-story flats and duplex structure dating back to 1921, currently owned by Sajid Sohail. The property underwent significant improvements in 2016, including a comprehensive remodel of the second-floor unit that expanded its habitable space, installation of two new furnaces, conversion to tankless water heaters, and extensive electrical upgrades including new receptacles, lights, switches, and sub-panels. The building's infrastructure was further enhanced with roofing work and sewer system updates in 2016, bringing the total modernizations that year to approximately $120,000.

Historical records indicate previous concerns about unauthorized living spaces, with complaints about an illegal basement unit dating back to 1994 and a garage-level unit cited in 2003. These violations were addressed and abated by June 2003, and more recent permits from 2016 sought to establish the legal use and occupancy of the building as two dwelling units over garage space. The property has also received regular maintenance attention, including moisture barrier installation and siding replacement in 2013.

Recent activity around the property has mostly involved external maintenance and urban management issues, with multiple 311 calls related to street cleaning, parking enforcement, and graffiti removal between 2021 and 2025. While there were historical violations regarding unauthorized units and habitability concerns from the 1990s and early 2000s, these issues appear to have been resolved through subsequent renovations and permit approvals. The building's major systems have been comprehensively updated in recent years, suggesting improved safety and comfort for current residents. The property's maintenance record shows regular attention to both building systems and exterior upkeep, with most recent 311 calls relating to street-level issues rather than building conditions.
