434-436 27th Ave, San Francisco, CA 94121

The two-unit, two-story multi-family residential building at 434-436 27th Avenue in the Central Richmond neighborhood, owned by Carey Duane Chin & Hui Xia, was constructed in 1923 as a flats and duplex structure. The building's maintenance history shows several significant improvements, including two separate aluminum window installations in 1985 and 1987, and reroofing work in 1998, though the roofing permit has since expired.

The property has experienced various infrastructure and maintenance issues over the past decade, with the most recent incident occurring in August 2024 involving abandoned furniture and debris on the street, which was resolved by Recology. A notable incident occurred in December 2021 involving a sewage backup incident that required attention from PUC Sewer Operations and was subsequently resolved.

The surrounding street infrastructure has faced some challenges, with two pavement defects reported in 2018 (April and July), both of which were resolved. The area has also seen multiple incidents of abandoned vehicles in early 2017, with three separate reports between January 21 and June 26 of that year, though all vehicles were gone upon inspection. Other external issues have included a loose street sign repair in November 2017 and an offensive graffiti incident on a pole in June 2014, both of which were addressed and resolved.
