347-349 17th Ave, San Francisco, CA 94121

The three-story multi-family residential building at 347-349 17th Avenue in the Central Richmond neighborhood is a duplex property built in 1912, currently owned by Liang Wah Chung & Feng Fu D. The building underwent significant renovation in 2005, which included substantial improvements to the upper unit #1 with the addition of a family room, bedroom, and bathroom on the first floor, along with associated electrical work.

More recently, in early 2022, important maintenance was performed including the replacement of dry rot on the back building stair landing and rear roof overhang, along with bathroom faucet replacement and an electrical upgrade that doubled the subpanel's capacity from 40-amp to 80-amp. The property has experienced recurring sewer-related issues in recent months, with two sewage backup incidents reported in 2024 (August and October), both involving the side sewer vent.

Additionally, there have been multiple parking-related incidents near the property between 2024 and 2025, including several cases of driveway blocking that required enforcement intervention, though many of these cases resulted in officers being unable to locate the offending vehicles. A significant maintenance issue from 2024 was reported in October regarding public utilities, while earlier incidents in 2024 included a human or animal waste situation on private property. The building's permit history also shows attention to basic infrastructure maintenance, including roofing work done in 1994, though this permit has since expired.
