458-460 28th Ave, San Francisco, CA 94121

The two-unit multi-family residential building at 458-460 28th Avenue in the Central Richmond neighborhood, owned by Henry J Wong, was constructed in 1924 and spans two stories plus a ground level garage. The property experienced significant regulatory issues in January 2010 when multiple complaints were filed regarding unauthorized modifications, including an illegal kitchen installation and bathroom modifications on the ground floor, which had been converted improperly despite previous permits for specific uses. These violations triggered enforcement actions, leading to required compliance work in February 2010 that removed unauthorized kitchen facilities and converted a shower room back to its original purpose.

The building underwent substantial improvements in 2004, including the addition of two bedrooms and a half bathroom on the ground floor, along with electrical system upgrades and insulation work. More recent maintenance issues have been documented, with a sewer-related 311 call in July 2022, though this appears to be an external infrastructure matter rather than a building-specific problem. The property's compliance history shows successful resolution of the 2010 violations, with all related permits marked as complete.

Earlier building history includes a reroofing project from 1992 and stair repair work from 1985, indicating regular maintenance attention. More recent external issues have been limited to routine municipal service matters, such as parking enforcement and sidewalk access concerns, which were not directly related to the building's structural or habitability conditions. The most significant past challenges regarding improper unit modifications and plumbing systems appear to have been adequately addressed through the 2010 compliance work and subsequent permits, suggesting improved regulatory adherence in recent years.
