2270-2272 Mission St, San Francisco, CA 94110

The two-unit residential building at 2270-2272 Mission Street, owned by Tan Thai Investments LLC and built in 1907, has experienced several significant events over its history, with particular attention required to recent fire safety concerns. The building underwent a major renovation in 2007-2008, converting office space and restroom facilities for a dental office on the ground floor, including substantial plumbing and electrical upgrades totaling approximately $45,500. A previous fire incident occurred in 1991, and more recently, the property has faced recurring fire safety violations, with the most recent being an electrical systems issue in November 2024 and a fire extinguisher violation in the same month.

The building's fire protection systems have shown areas requiring attention, with violations recorded in both 2022 and 2023 regarding alarm systems, sprinkler systems, and exit maintenance. The property has undergone various structural and safety-related improvements over the years, including siding repairs in 2008 following a violation, and multiple sidewalk repairs between 2004 and 2007. A notable building complaint was filed in 2008 regarding water/rot damage affecting neighboring properties, though this was abated within a couple of months.

Recent activity on the property includes a 2024 complaint about a solid roll-security gate installation that was submitted for review. The surrounding area has experienced periodic maintenance issues as evidenced by multiple 311 calls in late 2024, primarily related to street cleaning and graffiti, though these are external to the building itself. While the building has had several maintenance issues over the years, it's worth noting that most violations have been addressed and abated, indicating compliance with required corrections, though the frequency of recent fire safety violations suggests ongoing monitoring of these systems is necessary.
