5045-5047 California St, San Francisco, CA 94118

The two-unit residential building at 5045-5047 California Street in San Francisco's Inner Richmond district was built in 1942 and is currently owned by Huang Hui Wen & Yang Hui Xi. The property has undergone several significant modifications over the past two decades, with the most substantial work completed in 2011, including the conversion of the garage level into a family daycare facility for 12 children, which involved creating a one-hour rated hallway, adding a full bathroom, and installing smoke detectors. This renovation was accompanied by comprehensive updates to the building's infrastructure, including plumbing work to add a bathroom with shower, vanity, and toilet, replace laundry facilities, and upgrade heating systems.

The electrical system received a major upgrade in 2011, boosting service from 80 to 200 amps and installing two 100-amp panels with multiple circuits. The building has faced some regulatory challenges, most notably in 2020 when complaints were filed regarding two unauthorized structures in the rear yard that reportedly blocked a neighbor's window and resulted in improper garbage placement. This violation was eventually abated by November 2020.

Earlier complaints in 2012 also addressed unauthorized construction in the backyard, though this was resolved within weeks. The property has maintained compliance with building codes since these issues were addressed, and there have been no recent violations. Other records show routine neighborhood issues typical for the area, including several 311 calls for street cleaning and graffiti removal between 2010 and 2022, as well as reports of abandoned vehicles and illegal postings, none of which directly relate to the building's condition or operation.
