3420-3430 26th St, San Francisco, CA 94110

The 6-unit residential building at 3420-3430 26th Street in San Francisco's Inner Mission neighborhood is a three-story flats structure built in 1907 currently owned by 3420-3430 26th Street LLC. The property has undergone several significant modifications and faced multiple maintenance challenges over the years. Most recently, in 2023, two new furnaces and associated plumbing work were installed, and an accessory dwelling unit (ADU) was created in 2022 with proper electrical installations.

In 2018, important fire safety improvements were initiated with plans to upgrade the rear building wall to a one-hour fire rating. The building has experienced recurring pest issues, with the most recent complaint in 2023 reporting non-functional laundry facilities and mouse problems, echoing similar complaints from 2017. Past violations from 2004 and 2011 highlighted various safety concerns, including the need for smoke detectors, fire safety equipment, and ceiling fan repairs, all of which were eventually abated.

The property's maintenance history shows attention to infrastructure improvements, including a new bathroom and kitchen plumbing installation in 2020, and a 4-inch main sewer line upgrade. Various historical permits show past work such as reroofing (1998), stair repairs (1990), and window replacements (1988). Recent inspections have revealed ongoing exterior maintenance needs, as evidenced by multiple 311 calls in late 2024 regarding sidewalk debris and cleaning issues, though these appear to be related to public space rather than direct building maintenance problems. A notable building inspection in 2014 documented multiple interior issues including flooding, non-operational smoke detectors, and drainage problems, suggesting periodic challenges with building systems and maintenance responsiveness.
