1478-1480 9th Ave, San Francisco, CA 94122

The Huang Family Trust owns this two-unit, two-story multi-family residential building located at 1478-1480 9th Avenue in the Inner Sunset neighborhood. Built in 1912, this flats and duplex structure has undergone several significant modifications over the years, with the most pressing concerns centering around unit legalization and potential habitability issues. Most notably, there is currently an active housing inspection complaint filed in May 2015 regarding a possible illegal unit and concerns about building safety, along with a prior complaint from March 2014 mentioning unpermitted kitchen/bathroom remodeling and overcrowding issues.

The property has seen multiple improvements, including a $15,000 kitchen renovation in 2015 (unit 1478) with associated electrical upgrades, and substantial garage-level modifications in 2009 that added two bedrooms, a half bathroom, and an office space at a cost of $60,000. The building's maintenance history shows attention to structural integrity, with an attempt to install anchor bolts in 1998, though this permit expired, and a garage door replacement in 1997. Electrical system upgrades have been completed, including an underground service conversion in 2003 and extensive garage-level electrical work in 2009.

The property has experienced regular maintenance issues typical of the area, with recent 311 calls for graffiti removal in October 2023 and general cleaning in May 2021. Historical records from 2012-2015 indicate efforts to legalize additional bathrooms and address various building improvements, though some permits were filed rather than completed. While the building has received various upgrades and maintenance work over the years, the most concerning aspect remains the unresolved housing inspection complaints regarding unit legality and building safety from 2014-2015.
