2633-2635 20th St, San Francisco, CA 94110

The two-unit residential building at 2633-2635 20th Street in the Inner Mission, constructed in 1907, has undergone several significant improvements over recent years, with particular attention to modernization and structural integrity. Most notably, in 2023, the property received substantial infrastructure upgrades including voluntary foundation work costing $148,400, complete sewer pipe replacement in the basement, and a 200-amp electrical system upgrade with new sub-panels.

The building has also seen the installation of multiple solar photovoltaic systems, with the most recent permits issued in early 2024 for systems ranging from 3.44 to 4.32 kW, demonstrating a commitment to sustainable energy. The property has maintained consistent upkeep through the years, with major renovations completed in 2011 including exterior stair replacement, interior remodeling of kitchens and laundry areas on multiple floors, and facade improvements.

Earlier improvements from the early 2000s included bathroom renovations, reroofing work, and structural strengthening with the installation of anchor bolts. The building's maintenance record shows regular attention to both aesthetic and functional elements, though there have been some recent environmental challenges in the surrounding area, including a currently open sidewalk defect related to tree roots (as of November 2024). The property has experienced minimal reported issues, with only two instances of graffiti on the building in 2023 and multiple street cleaning matters in the vicinity, all of which were promptly addressed and resolved.
