The property at 5939-5941 California Street is a two-unit residential building (Flats & Duplex) located in San Francisco's Central Richmond neighborhood, built in 1922 and currently owned by the Huizhen Liang Family Trust. The building has undergone significant renovations over the past decade, with the most substantial work occurring between 2012-2017, including major bathroom and kitchen remodels in both units, installation of new bathrooms, laundry facilities, and comprehensive electrical rewiring with new service entrance and panel board installations.

Initial permits totaling $50,000 were issued in 2012 for various improvements including addressing dry rot issues, with subsequent revisions and renewals in 2016-2017, indicating ongoing work to complete the approved projects. A plumbing permit from 2012 shows the installation of new plumbing fixtures in both units, with additional work on gas systems and HVAC equipment, including furnace installations. The building's maintenance history also includes a complete reroofing project in 2009 costing $8,000, demonstrating attention to basic building upkeep.

A complaint was filed in 2016 regarding suspected unpermitted work, specifically mentioning multiple contractors entering the property, though this complaint's current status is listed as not active. Recent external issues in the vicinity of the property include a damaged tree and pavement defect reported in 2023, and various street maintenance concerns such as overflowing garbage cans and sidewalk cleaning needs were documented through 311 calls between 2018-2024, though these are general neighborhood issues rather than building-specific problems. The extensive permit history suggests that significant improvements have been made to both units, focusing on modernization and maintaining safety standards, with most recent work typically being properly permitted and completed.
