443-445 28th Ave, San Francisco, CA 94121

The three-story multi-family residential building at 443-445 28th Avenue in San Francisco's Central Richmond neighborhood is a duplex property built in 1919, currently owned by the Wendy W F Kwan Living Trust.

The building has undergone several significant renovations over the past few decades, with the most notable recent work occurring in 2006 when electrical upgrades were completed to install new outlets, lights, switches, and upgrade the electrical service to 200 amps with three meters, along with a ground floor renovation that added a bedroom, family room, and half bath while also modifying a rear door into a window. The property has maintained a relatively low number of complaints and issues, with only one recent building-related complaint noted in 2020 regarding unauthorized construction work, which is currently listed as not active.

Two infrastructure-related incidents have been documented through 311 calls: a parking enforcement issue in March 2024 that was unable to be verified by responding officers, and a water leak incident in April 2017 that required repair work. The building's historical maintenance record shows attention to basic upkeep, with repairs for dry rot on rear stairs in 1999, installation of new roofing in 1993, and an authorized street space permit from 2006.
