1447 20th Ave, San Francisco, CA 94122

The property at 1447 20th Avenue in the Central Sunset is a two-unit, two-story multi-family residential building constructed in 1941, currently owned by Moon Yu and Alice Chang Lee R. The building's maintenance history shows two significant permitted improvements: a roofing project completed in 2011 at a cost of $7,000, and a vertical and horizontal addition completed in 1987.

The building's recent history has been marked by several parking-related issues, particularly in 2018, when there were multiple reports (seven in total) of sidewalk parking violations, though enforcement officers often either could not locate the vehicles or were unable to validate the reports. A more recent parking enforcement incident occurred in June 2023, involving a bicycle lane blockage.

Other issues in the vicinity include two instances of loose garbage requiring general cleaning in 2016 and 2019, and a non-offensive graffiti incident in 2016 that resulted in administrative closure by Public Works. While the historical record shows several quality-of-life issues in the immediate area, particularly relating to parking violations, there are no documented safety concerns or structural issues with the building itself.
