645 9th Ave, San Francisco, CA 94118

The Chi & Cheung Family Trust owns this 4-unit, 2-story multi-family residential building located at 645 9th Avenue in San Francisco's Inner Richmond neighborhood. The building, constructed in 1973, has experienced several notable events over its history. Three routine housing inspections took place in the early 2000s, with violations noted in April 2002 related to fire safety issues including egress obstructions, fire extinguisher requirements, and smoke detector installations, all of which were abated by May 2002.

A subsequent inspection in March 2007 identified additional fire safety concerns regarding directional signs and combustible storage, which were also resolved by May 2007. The most recent routine inspection occurred in 2011, with no active violations recorded. The building has undergone some maintenance work, including a reroofing project initiated in 1994, though this permit has since expired.

More recently, there have been two service-related incidents: a sewage backup issue in December 2021 that was resolved through PUC Sewer Operations, and an abandoned property service request in August 2018 that was addressed by Recology. While the building has experienced various compliance and maintenance issues over the years, all known violations have been addressed and resolved. The property's documented history shows regular oversight through routine inspections, with no active violations on record as of the latest inspection.
