837-839 Oak St, San Francisco, CA 94117

The property at 837-839 Oak Street is a two-unit, two-story multi-family residential building located in Hayes Valley, owned by David L. and Carol E. Holcomb.

Built in 1890, this flats and duplex structure has undergone several documented improvements over the years, including the installation of six energy-efficient replacement wood windows in 2006 (with a U-value of .38-.52) and compliance work following a physical inspection in 2000. Historical records show two significant safety concerns from the late 1990s: a November 1997 complaint regarding heating issues and structural problems including a collapsing porch and missing stairs, which was abated within a month, and an expired permit from 1989 for reroofing work. The most recent history of the property shows several maintenance and safety issues in the immediate vicinity, though not directly related to the building itself.

Between 2022 and 2024, there have been multiple reports of urban concerns including graffiti (most recently in April 2024), hazardous materials (glass) street cleaning needs (November 2023), illegal postings, and parking violations. A fallen tree incident was reported and resolved in May 2024, and there was one noise complaint related to entertainment in September 2022. While these external issues indicate typical urban neighborhood challenges, most have been promptly addressed by appropriate city agencies. The building's permit and complaint history suggest that major structural and safety problems have been addressed over two decades ago, with no recent building-specific complaints or permits on file.
