471 18th Ave, San Francisco, CA 94121

This two-unit multi-family residential building, located at 471 18th Avenue in the Central Richmond neighborhood, was constructed in 1921 and has experienced several maintenance and infrastructure events over its lifetime. The property, owned by Martina My Lai Tr, has undergone three significant structural improvements: a complete reroofing project in 2013 costing $3,000, sidewalk repairs in 2010, and the repair of rotted rear stairs completed in 1985, which affected both floors of the two-story structure.

Of particular note is a sewage backup incident in May 2021 involving a 4-inch sewer vent, which was resolved by PUC Sewer Operations. The building's recent history (2018-2022) shows a pattern of parking-related issues in the vicinity, with multiple reports of abandoned vehicles and parking violations, though most were resolved promptly.

There have been two documented infrastructure concerns - a curb defect reported in 2017 that was noted to exceed city specifications, and a sidewalk parking violation in February 2020. The property has also seen routine municipal interactions such as general cleaning in 2008, and requests for service related to street painting in 2020. While the building has required various maintenance work over the years, the documented permits suggest regular upkeep of major systems, with no recorded violations or safety concerns in the recent decade.
