1307 21st Ave, San Francisco, CA 94122

The two-unit residential building at 1307 21st Avenue in the Central Sunset neighborhood is a two-story flats and duplex structure built in 1916, currently owned by Kwan Ying C & Marilyn. The building has undergone several significant maintenance works over the years, including two major roofing projects - one completed in 1989 and another costing $7,500 in 2016. In 1998, there was an electrical system issue reported when fuses were blowing, though this complaint was resolved within six months.

The most recent building permit on record from 2018 involved street space work with a nominal cost. The property has experienced considerable recent activity in terms of street-related issues, particularly between December 2024 and January 2025, with multiple reports of garbage and debris on the surrounding streets and sidewalks. These included instances of human waste, furniture dumping, and overflowing city garbage cans, with several cases remaining active or unresolved as of January 2025.

While these external environmental issues are noteworthy, they pertain to the public space rather than the building itself. The only recorded fire incident was a service call with no civilian injuries involved. The building's documented maintenance history shows regular upkeep of major systems, though the age of the structure (107 years old) warrants attention to ongoing maintenance needs.
