456 9th Ave, San Francisco, CA 94118

The 4-unit, 2-story multi-family residential building at 456 9th Avenue in San Francisco's Inner Richmond district, owned by Hanlon J Fong Tr, was constructed in 1977 and has undergone several significant renovations and maintenance activities over the past decade. The most recent work, completed in August 2023, involved reroofing at a cost of $13,800.

In 2021, a substantial renovation of Unit 3 was executed, including kitchen and two bathroom remodels, with the work properly permitted through building, plumbing, and electrical permits totaling $48,000. A notable incident occurred in late 2016 when unpermitted bathroom remodeling work led to a building violation complaint and subsequent noise complaints from neighbors, though this situation was eventually resolved through proper permitting and completion of the work by November 2018. The building has experienced various maintenance and service calls over the years, including routine housing inspections in 2001 and 2010, and several 311 calls addressing different issues such as sidewalk defects (2014), general cleaning needs (2012 and 2022), and construction noise (2016).

While there have been multiple fire department responses to the building, these were all related to either false alarms or system activations with no fires or civilian injuries reported. The property has maintained an active record of addressing necessary repairs and improvements, as evidenced by the proper completion of various permits and resolutions of complaints. However, the initial unpermitted construction work in 2016 and associated noise complaints represent the most significant disruption to resident experience on record.
