1459-1461 Thomas Ave, San Francisco, CA 94124

The two-unit residential building at 1459-1461 Thomas Ave in San Francisco's Bayview neighborhood is a two-story flats and duplex structure built in 1900, currently owned by Sakai Yuhki. The property has undergone several significant improvements over the past decades, with the most substantial renovations occurring in late 2015 when comprehensive work was completed to legalize and remodel multiple bathrooms and kitchens, along with electrical rewiring, installation of new subpanels, and plumbing updates including laundry room modifications.

The building received earlier window upgrades in 1985-1986 with the installation of aluminum windows, and vinyl siding work was attempted in 2000 but the permit expired. The property has faced various maintenance and safety issues in recent years, particularly in 2024-2025, including problems with collapsed sidewalks, sewer-related incidents (water leak and sewage backup discharge), and mold/mildew concerns. Environmental health and urban forestry departments have been involved due to these issues.

Historical data shows the building had a nursing home extension proposal in 2008-2009 to increase capacity from 6 to 8 patients, which was approved. While there was one electrical systems complaint in 2018, it was found to have no merit, and an earlier complaint about weeds and grass in 2008 was promptly resolved. Recent 311 calls primarily relate to external issues such as sidewalk defects, garbage, and parking concerns, rather than building-specific problems.
