642-644 Russia Ave, San Francisco, CA 94112

The two-unit multi-family residential building at 642-644 Russia Avenue in Excelsior, owned by Tsang Yuk Ming, was constructed in 1947 and is classified as a Flats & Duplex structure. The property has undergone several notable improvements over the years, with the most significant recent development being the addition of a 374 SF one-bedroom ADU unit on the first floor, completed under the state program in 2022 at a cost of $86,000. Prior renovations include a comprehensive kitchen and bathroom remodel in 2014 ($9,500), repairs to back stairs and siding in 2020 ($8,000 combined), and older improvements from 1989 including roof replacement and stucco patching.

The building's history includes a documented complaint in September 2020 regarding unauthorized construction of a two-story deck and stairs in the rear yard, though this issue appears to have been resolved as it is no longer active. More recently, from April to September 2024, there have been multiple reports of garbage and debris issues near the property, and three separate complaints about sidewalk parking violations involving a Dodge vehicle. These parking violations were addressed by enforcement officers.

Additionally, there is currently an open noise complaint filed in July 2024. While these recent complaints primarily relate to exterior and public space issues rather than building conditions, they may impact resident experience. The property's maintenance record shows regular upkeep, with structural and systems improvements completed systematically over the years, including plumbing and electrical upgrades during the 2014 remodel, suggesting responsible property maintenance overall.
