431 15th Ave, San Francisco, CA 94118

The two-unit residential building at 431 15th Avenue in San Francisco's Central Richmond district is a two-story flats/duplex structure built in 1922 and currently owned by the Peter Haw Sheng Huang Trust. The building's maintenance history shows regular attention to upkeep, with the most recent significant work being a $12,900 reroofing project completed in 2021, following a previous reroofing attempt from 1997 (which expired).

Earlier structural and aesthetic improvements included a wall repair at the front of the building in 1992 and kitchen remodels in 1985 and 1991, though the kitchen cabinet change permit from 1991 expired without evidence of completion. The property's recent history has been marked by numerous street-level maintenance issues, particularly in 2023-2024, with multiple reports of abandoned garbage and debris on the surrounding sidewalks, including three incidents in 2024 alone involving mattresses, bagged garbage, and other loose debris.

There were also reports of hazardous materials (glass), parking violations (a truck parked on the sidewalk), and tree maintenance needs in 2024, though most of these cases were resolved through appropriate channels. The building's immediate vicinity has required regular cleaning attention, with several reports between 2023-2024 indicating ongoing street maintenance needs. While these exterior issues don't directly impact the building's internal conditions, they do suggest some challenges with the immediate neighborhood's upkeep and maintenance.
