1331-1333 35th Ave, San Francisco, CA 94122

The two-unit residential building at 1331-1333 35th Avenue in the Central Sunset neighborhood is a two-story flats and duplex structure built in 1946, currently owned by Chuk H. & Wai Yu Wong Kwan F.

The building has undergone several notable improvements and maintenance work over the years, including a conversion from gas to electric heating in 1999, a significant renovation adding a family room, bedroom, bathroom, and extended playroom in the same year, and various plumbing upgrades in 2009 that included replacing fixtures and pipes. The garage received an automatic door opener installation in 2004, and two minor fire incidents were recorded - a contained cooking fire and a smoke detector activation, neither of which resulted in civilian injuries.

Recent external environment issues have been documented through 311 calls, with the most pressing concerns being multiple reports of abandoned vehicles (two incidents in late 2023 and one in 2024), parking violations including driveway blocking and sidewalk parking in 2024, and some street maintenance matters such as graffiti and curb defects, though most of these issues have been promptly resolved. While the building's interior systems have received regular updates over the years, including the notable 1999 renovations and plumbing work in 2009, the property has experienced recurring issues with street parking and abandoned vehicles in the vicinity, which might impact resident convenience.
