4730-4734 California St, San Francisco, CA 94118

The multi-family residential building at 4730-4734 California Street, owned by Angel Ng, is a three-story, three-unit flats and duplex structure built in 1907 and located in the Lake - The Presidio neighborhood. The most significant recent improvement was a comprehensive renovation completed in 2021, costing $60,000, which included kitchen and bathroom remodeling, electrical rewiring, and plumbing upgrades such as fixture replacements and central heating installation.

This renovation addressed several previous concerns, including the removal of an inadequate heating system that had been reported in 1998. The building had notable maintenance history, including dry rot repairs in 1998 and compliance work in 2001 that addressed multiple violations related to fire proofing, egress obstruction, and plumbing/electrical issues, all of which were successfully abated by April 2001. The property has experienced several infrastructure issues over the years, with 311 calls in recent years primarily related to external maintenance matters such as pavement defects (2016), tree overgrowth (2020), and one flooding incident (2019) that was resolved promptly.

While there have been periodic complaints and violations, particularly in 2001 when multiple housing inspection issues were documented, these have all been resolved. More recent complaints have primarily concerned external factors like parking violations and street maintenance, rather than building-specific issues. The most recent building-related permit activity was in 2021, and there have been no major building violations or complaints recorded in recent years, suggesting improved maintenance and compliance since the 2021 renovations.
