637-639 29th Ave, San Francisco, CA 94121

The two-unit multi-family residential building at 637-639 29th Avenue, owned by the Chen Tung Woo Family Trust, was constructed in 1961 in the Central Richmond neighborhood. The property has undergone several significant improvements in recent years, with the most substantial current project involving interior renovations on the second level unit, including wall modifications, kitchen and bathroom remodeling, and structural improvements, at an estimated cost of $80,000 (issued June 2024).

In early 2024, the building addressed compliance requirements from a physical inspection report (CC-8646) through various improvements totaling $4,000, and this work has been followed by additional plumbing and electrical upgrades, including kitchen rewiring and bathroom renovations (both issued November 2024). A major electrical system upgrade was completed in 2022, including a service increase from 125 amps to 320 amps, installation of a third meter, and replacement of subpanels in both units. The building has a history of maintenance and improvements over several decades, including reroofing work completed in 2004 and window replacements in 1997.

While there have been multiple reports of abandoned vehicles and some neighborhood maintenance issues (such as toters left out and a tree pruning request) documented through 311 calls between 2019 and 2023, these incidents generally relate to the surrounding area rather than building-specific concerns. The property's most recent significant improvements have focused on modernizing the infrastructure and addressing safety compliance requirements, with all major systems being actively maintained or upgraded. The building's 1998 dry rot repair indicates attention to structural maintenance has been ongoing, though no such issues have been reported in recent years.
