3917 California St, San Francisco, CA 94118

The three-story, two-unit multi-family residential building at 3917 California Street in San Francisco's Inner Richmond district was built in 1900 and is currently owned by Thanh D Thai & Bich D Hoang. The property experienced significant code enforcement issues in 2015 when complaints were filed regarding unpermitted construction, specifically the installation of an additional kitchen in the lower portion of the building.

This led to multiple Notices of Violation and the requirement for substantial remedial work, including the removal of the illegal kitchen, conversion to laundry facilities, and legalization of an existing bedroom on the ground floor, as well as kitchen and bathroom remodels on the second floor. These violations were eventually resolved through permits totaling $45,000 in improvements, completed by 2016. More recently, the property has generated numerous parking enforcement calls, particularly in 2024, with multiple reports of vehicles blocking driveways and parking on sidewalks.

Records show ten parking-related incidents between March 2024 and November 2024, with citations issued in several cases, though officers were often unable to locate the vehicles or the issues were addressed through other means. The building's plumbing and electrical infrastructure has seen some documented improvements over the years, including a gas houseline extension in 2007, and the 2015 permit work included extensive electrical upgrades comprising new lighting, switches, receptacles, and appliance installations. A storage room and toilet addition was previously completed in 1998.
