243-245 Lexington St, San Francisco, CA 94110

The two-unit residential building at 243-245 Lexington Street in San Francisco's Inner Mission neighborhood, owned by Tan Hui Zhu, is a two-story flats and duplex structure built in 1912. The building has a limited permit history, with records showing a street space permit issued in 2009, a reroofing project from 1993 (now expired), and staircase repairs from 1989 (also expired).

More recently, the property has faced several significant maintenance challenges, particularly in relation to its sewer infrastructure. Between April and June 2023, there were three documented sewer-related incidents, including two sewage backup incidents from a 4-inch vent in April and one catch basin discharge in June 2024.

The area around the building has experienced recurring issues with street cleanliness, as evidenced by multiple 311 calls throughout 2024 reporting garbage, debris, and waste on or near the property. The most recent service request was in December 2024, and while some cases required no further action, others were resolved through cleaning efforts. The building's exterior has also been affected by vandalism, with three documented incidents of non-offensive graffiti between 2023 and 2024, all of which have been resolved.
