487 Potrero Ave, San Francisco, CA 94110

The 3-unit, 3-story multi-family residential building at 487 Potrero Avenue in Potrero Hill, built in 1986 and currently owned by the Dorothy W Choi Bypass Trust, has undergone several significant maintenance and infrastructure improvements over the years. Most recently, in July 2022, the building completed a house trap and sewer lateral replacement, addressing important plumbing infrastructure.

The property has experienced periodic maintenance and upgrade work, including a $13,320 reroofing project in 2014, vinyl siding installation in 1990, and a notable subdrain deletion beneath the garage slab in 1985. The building's history includes several violations in March 2004 related to fire safety and building maintenance, particularly concerning fire escape ladders, roof deck repairs, and egress obstructions, all of which were abated by April 2004.

More recent concerns include a complaint in October 2022 about possible unpermitted construction work, and a noise complaint related to construction in June 2015. The property has experienced recurring issues with graffiti, with the most recent incidents reported in 2023, and has been the subject of various 311 calls for topics including sidewalk cleaning, blocked parking spaces, and construction-related concerns. While there have been two fire incidents recorded at the address, both were minor—one being an unintentional alarm system activation and the other an invalid assist, with no civilian injuries reported in either instance.
