3267-3273 25th St, San Francisco, CA 94110

The property at 3267-3273 25th Street in San Francisco's Inner Mission district is a two-story, 4-unit multi-family residential building constructed in 1915 and currently owned by Stephen Karpman. The building has a documented history of maintenance and safety issues, with the most recent significant complaint occurring in February 2017 regarding water intrusion and mold in the rear building, which was reported as having yellow discoloration and black mold for months.

This followed a pattern of plumbing and structural concerns, particularly notable during 2010-2011 when multiple violations were recorded related to sewer infrastructure, including the absence of required fresh-air inlets and house traps, which resulted in chronic sewer stoppages. The building underwent some repairs during this period, including work on fresh-air vents, house traps, and gas lines in 2010, though these issues highlighted significant plumbing system deficiencies. Historical records from the 1990s show a range of maintenance challenges, including issues with heating systems, peeling paint, broken windows, and problems with stairs and handrails, particularly noted in multiple complaints from 1994 through 1999.

The property has seen various repairs attempted over the years, including window repairs and handrail installation in 1999, reroofing work in 1997, and more recent plumbing infrastructure improvements. While many historical violations have been marked as abated, the property's maintenance history shows recurring patterns of infrastructure and safety concerns, particularly regarding plumbing systems and basic building maintenance. Recent 311 calls from 2024-2025 primarily concern external issues such as garbage and debris, though these are less directly related to building habitability concerns.
