3161-3163 Mission St, San Francisco, CA 94110

The three-story multi-family residential building at 3161-3163 Mission St in Bernal Heights, owned by Patricia Medina, was constructed in 1900 and contains 3 residential units plus ground-floor commercial space. The property has undergone several significant modifications and improvements since 2006, most notably the establishment of a preschool facility in 2012 that included extensive safety system upgrades (fire life system, smoke alarms, etc.), commercial space renovations, and new plumbing and electrical work. The building experienced multiple violations in 2006 related to unpermitted plumbing and renovation work, though these were abated by 2008.

Since then, there have been recurring issues with the fire alarm system, with multiple activations recorded between 2006 and 2020, though all appear to be false alarms or system malfunctions with no injuries reported. More recent complaints include a broken washer and dryer (active as of October 2024) and a notable incident in 2013 involving T&P pipes near the preschool area, which was resolved within a week. The building's infrastructure has been consistently maintained, with major systems such as plumbing (including repiping of bathrooms and kitchens) and electrical (including new service entrance and comprehensive rewiring) being properly updated between 2007-2012, though some work has required multiple permits and inspections to complete. Recent 311 calls from 2023-2024 have primarily related to external issues such as sidewalk cleanliness and graffiti, rather than internal building problems.

The building has experienced some parking and accessibility concerns as evidenced by 311 calls, but these relate more to street conditions than the building itself. The most recent fire safety inspections and incidents suggest a generally responsive maintenance pattern, with issues being addressed promptly, though the frequency of alarm system activations indicates ongoing monitoring requirements. Child care facility-specific improvements from 2012 remain in place, including safety systems monitored by ADT central station. The property's maintenance history shows a pattern of addressing violations and maintaining required systems, though some aspects (like the fire alarm system) exhibit recurring issues that have been documented over several years.
