4727-4731 California St, San Francisco, CA 94118

The three-story multi-family residential building at 4727-4731 California Street, located in San Francisco's Inner Richmond neighborhood, is a 4-unit apartment building constructed in 1908 and currently owned by Fu Kwock & Yuet Sim Fung Ng. The property has undergone several significant maintenance projects over the years, including multiple reroofing efforts (most recently in 2008 costing $10,500), kitchen and bathroom remodeling in 1998, and correction of code violations in 1987.

The building has been subject to regular housing inspections, with notable violations recorded in 2017 including fire escape ladder maintenance, water heater flue issues, and safety equipment requirements such as carbon monoxide detectors and fire extinguishers, all of which were abated by February 13, 2017. Earlier routine inspections in 2003 and 2009 also identified issues requiring attention, though all were resolved. The building's maintenance history shows attention to basic infrastructure, with records of roof repairs and interior improvements, though some permits have expired without documentation of completion.

Recent external maintenance issues noted through 311 calls include a streetlight repair in 2021, general street cleaning in 2020, and various neighborhood concerns such as illegal postings and graffiti in prior years. A noise complaint was filed in 2017 regarding amplified sound, and there was one report of an abandoned vehicle in 2014, though these are more reflective of neighborhood conditions rather than building-specific issues. The property's documented history shows regular engagement with housing inspection requirements and prompt response to identified violations, though the pattern of routine inspections suggests ongoing attention to building maintenance and safety compliance has been necessary.
