845-849 Diamond St, San Francisco, CA 94114

The property at 845-849 Diamond Street is a two-story, three-unit multi-family residential building located in Noe Valley, constructed in 1900 and currently owned by the Elaine R Tisell 2002 Trust. The building's infrastructure has received several important updates over the years, including a significant electrical upgrade in 2011 with the installation of a new 200-amp, 240-volt 5-gang meter socket and main service panel serving multiple addresses in the vicinity.

In 2006, street space was temporarily utilized for scaffold work, and historical records show earlier maintenance activities including the replacement of dry rot to mud sill and studs in 1999, and reroofing work in 1995. Of particular note are several building violations documented in late 2002 relating to fire safety concerns, including issues with fire extinguishers, smoke detectors, combustible materials in the basement, and egress obstructions. These violations were all addressed and abated by January 2004.

The building has experienced recurring plumbing issues as evidenced by two sewage backup incidents reported in 2022 (March and June), and more recently, there have been multiple reports of sidewalk parking violations near the property throughout 2023 and 2024. While most of these parking enforcement cases resulted in inability to locate the vehicles or other resolutions, one resulted in a citation being issued in May 2024. The property's maintenance record suggests that while there have been periodic issues requiring attention, most historical violations have been resolved, with the most recent infrastructure improvements focusing on electrical systems.
