681-683 16th Ave, San Francisco, CA 94118

This two-unit, two-story multi-family residential building, located at 681-683 16th Avenue in the Central Richmond neighborhood, was built in 1920 and is currently owned by Diane P. Perrine.

The building's maintenance history reveals several significant plumbing issues, most notably a broken or defective house trap reported in May 2023 that was classified as causing health and sanitation concerns under various plumbing codes. This plumbing situation appears to be part of a broader infrastructure concern, as there were also reports of sewage backup in May 2023 and some plumbing work performed in January 2017 including secondary line replacement and spot repairs. The building has undergone various improvements over the years, including roofing work in 2005 (permit expired) and an extensive chimney-related upgrade in 2009 that involved the installation of a stainless steel flue, exhaust fan, and associated electrical work.

Historical records show the building was inspected for fire safety in 2012 with two complaints regarding combustible materials and blocked exits, though both were found to have no merit. More recent incidents include two parking enforcement calls regarding sidewalk parking in 2022 and 2023, and a flickering streetlight complaint in 2012 that was resolved by PG&E. The property's permit history indicates regular maintenance work, though the plumbing system appears to have experienced recurring issues, with administrative records showing both completed and withdrawn permits for various chimney-related work in 2009.
