3441-3443 26th St, San Francisco, CA 94110

The 3441-3443 26th Street property is a two-unit, two-story multi-family residential building located in San Francisco's Inner Mission neighborhood, constructed in 1900 and currently owned by the 26th Street Residence Trust. The building underwent significant transformation in 2016-2019, including the conversion of a non-conforming ground floor commercial space into residential use, complete with rear horizontal expansion, bathroom additions, and kitchen renovations costing $181,000. This period also saw comprehensive infrastructure updates, including radiant heating system installation, new bathroom and laundry facilities on both floors, and modernization of utilities including a tankless water heater.

The property has a history of building violations from 2008 related to an unpermitted hot tub installation on the roof and expired permits, though these were ultimately abated in 2012. There was a serious building complaint in 1998 regarding roof leaks, cracked walls, and ceiling issues, which was resolved by 2000. Recent years have shown ongoing maintenance activity, including window replacements in 2013, electrical system upgrades, and various plumbing improvements.

The building received facade modifications in 2016 to restore base and side paneling, and historical records indicate past issues with unpermitted storefront facade removal and a lot-line window installation, though these were addressed through proper channels. The most recent building systems improvements include a completed electrical service relocation and various plumbing updates in 2019. The property has experienced recurring street-level sanitation issues as evidenced by multiple 311 calls in recent months (2024-2025) regarding garbage and debris, though these are more reflective of the street environment than building conditions.
