1405-1407 12th Ave, San Francisco, CA 94122

The two-unit residential building at 1405-1407 12th Avenue in San Francisco's Inner Sunset neighborhood is a two-story flats and duplex structure built in 1947, currently owned by the Janice Siu Jin Jeong Trust. The building's documented history shows typical maintenance activities, including a completed reroofing project in 2001 costing $4,800 and a street space-related permit issued in 2014.

The property has experienced several incidents requiring municipal attention over the past decade, though none directly related to the building's condition or safety. These incidents primarily involved street-level issues, including sidewalk cleaning matters, with the most recent being a 2022 general cleaning call regarding loose garbage that was resolved with nothing found.

A 2021 report of medical waste (needles) on the street was resolved, and there have been three reports of abandoned vehicles in the vicinity between 2016 and 2018, though none were present when authorities arrived. An expired street space complaint was addressed in 2013 when a foreman was given 48 hours to renew the permit. The documented history suggests the building itself has been maintained according to standard requirements, with street-related issues being the most notable recurring theme in the property's external environment.
