642 Natoma St, San Francisco, CA 94103

The three-unit residential building at 642 Natoma St, owned by Ranjanben S & Anil Patel, is a 3-story TIC structure built in 1906 in San Francisco's South of Market neighborhood. The building has undergone several significant improvements in recent years, most notably a comprehensive $250,000 renovation in 2015 that included remodeling all three units' kitchens and bathrooms, adding new bathrooms and closets, and installing new furnaces. This was accompanied by complete electrical overhauls, with each unit receiving dedicated 100-amp services and new appliances, as well as a 200-amp main line installation in 2016.

Structural improvements were made in 2018 with voluntary strengthening of the basement walls, and maintenance work including a $23,850 reroofing project that same year. Recent plumbing work included a house trap replacement in 2020. The building's history shows regular maintenance and improvements, with several safety inspections conducted in the past. Although there was one fire violation in 2007 regarding fire extinguishers, this was promptly abated within one month.

While there have been multiple fire alarm activations recorded (primarily unintentional), smoke detector activations, and one gas leak incident, none resulted in civilian injuries or significant damage. The property has experienced recurring issues with abandoned furniture and debris on the sidewalk, as evidenced by multiple 311 calls in 2024, some of which remain open, indicating ongoing cleanliness concerns in the immediate vicinity. The most recent building-related activity was a curb defect report in November 2024. The owners appear to have maintained the property adequately, with most major improvements and repairs being properly documented and completed.
