651-653 Natoma St, San Francisco, CA 94103

The two-unit residential building at 651-653 Natoma Street in San Francisco's South of Market neighborhood is a two-story flats and duplex structure built in 1907, currently owned by Robert W. Page Jr.

The property has a documented history of renovations and permit violations, most notably in 2009 when unpermitted work was performed related to an instant hot water unit installation, electrical wiring, and exterior lighting, which led to multiple notices of violation. This resulted in subsequent permits being obtained to complete kitchen and bathroom remodels, including new fixtures, cabinets, tiles, and a switch to a tankless hot water heater, with final compliance achieved in 2012. The building has undergone several significant improvements over the years, including a complete reroofing project in 2007 costing $4,853, and various plumbing and electrical upgrades.

More recent maintenance issues include a missing side sewer vent cover reported in May 2023 (currently open as of the latest data) and multiple reports of human or animal waste on nearby streets between 2022-2023. While the building has experienced some violations and maintenance challenges, particularly related to the 2009 unauthorized renovations, many of these issues have been addressed through subsequent permitting and inspections, with documented corrections made to the electrical system and plumbing infrastructure. The most recent building-related concerns appear to be primarily maintenance and environmental health issues rather than structural or safety violations.
