2143-2145 Jones St, San Francisco, CA 94133

The two-unit, two-story multi-family residential building at 2143-2145 Jones St in San Francisco's Russian Hill neighborhood is a century-old structure dating back to 1909, currently held in trust by the Osborne Family Trust. The building's maintenance history shows several significant improvements, including a complete reroofing project in 2005 valued at $14,000 and foundation bolting work completed in 1993, which are critical for structural integrity.

In 2003, substantial interior work was undertaken, including floor insulation between the basement and first floor, installation of 5/8" gypsum board on the basement ceiling, and replacement of existing unframed components, along with electrical upgrades that added 5 circuits, 17 outlets, and 5 lights; however, these permits were either expired or renewed. The most recent permitted work was a minor street space and sidewalk permit issued in 2008. The building has maintained a relatively quiet record with only one reported incident in recent memory - a parking enforcement call in August 2023 regarding an illegally parked vehicle, which was promptly addressed by law enforcement.

Given the age of the building and the nature of the improvements, the property appears to have undergone necessary maintenance and upgrades over the years, particularly focusing on structural and safety elements such as the foundation and roofing systems. The absence of recent major repairs or renovation work, while not uncommon for older buildings, may suggest a period of relative stability in terms of building conditions. The property's documented history predominantly reflects routine maintenance and infrastructure improvements typical of a well-maintained residential duplex.
