632-634 18th Ave, San Francisco, CA 94121

The two-unit residential building at 632-634 18th Avenue in the Central Richmond neighborhood, owned by Wong Lvg Tr, is a 2-story property constructed in 1919. The building underwent significant modifications in the early 2000s, with building permits showing a horizontal addition project initiated in 2002 (valued at $150,000) to formally create the two-unit structure, though this permit ultimately expired.

This work continued in 2006-2008 with associated electrical work including the installation of two kitchens, four bathrooms, general lighting, and two new electrical panels, with costs totaling approximately $50,000. More recent building concerns include a documented heating system failure in December 2022 that took until March 2023 to resolve, and a complaint from 2013 regarding unauthorized construction work and debris issues affecting neighboring properties, though the resolution status is indeterminate. The building's more recent history shows ongoing maintenance and operational concerns, particularly in 2024, with multiple 311 calls regarding parking violations (including sidewalk parking and driveway blocking), flooding issues, and garbage problems.

There is also an open noise complaint from May 2023 regarding mechanical equipment. The property has been involved in various street space and electrical permits over the years, with the most recent significant infrastructure work appearing to be completed around 2007, including the installation of a garage door opener. The building's permit and complaint history suggests a pattern of both authorized improvements and unauthorized modifications, with particular attention needed to the property's heating system maintenance and parking-related concerns in the immediate vicinity.
