3270-3274 23rd St, San Francisco, CA 94110

The three-story, 6-unit apartment building at 3270-3274 23rd Street in the Inner Mission, owned by Phong Van & Kieu Loan Duong, was constructed in 1913 and has undergone several significant improvements over the past decades. Most notably, the building completed mandatory seismic upgrades in 2018 as a Tier 4 soft-story retrofit, involving both commercial and residential components, with a total investment of $80,000. In 2019, accessibility improvements were made with the installation of an ADA-compliant bathroom on the first floor, including new plumbing and electrical work.

The building has a history of maintenance and compliance issues, particularly evident in a series of violations documented in 2000, which included problems with stairs, windows, combustible storage, and fire safety features, though all were abated by January 2001. More recent years have shown attention to building maintenance and safety, with three fire complaints in 2021 being either found to have no merit or corrected, and the most recent soft-story retrofit work receiving proper certification. The property has experienced recurring issues with graffiti and sidewalk cleanliness, as evidenced by multiple 311 calls throughout 2023-2024, though most were resolved promptly.

A 1996 complaint regarding hazardous flooring conditions was addressed within three months, and there was a reported water leak in 1996 affecting a commercial space, which was resolved over approximately four years. The building's plumbing and electrical systems have received updates as part of the recent renovations, including the installation of new wiring for bathroom facilities in 2019. While the building's historical records show various maintenance challenges, recent improvements and completed safety upgrades suggest a focus on maintaining current building standards.
