818 25th Ave, San Francisco, CA 94121

The property at 818 25th Avenue is a 2-story, 2-unit multi-family residential building located in the Central Richmond neighborhood, constructed in 1923. The building's maintenance history shows regular upkeep, including multiple roofing projects (1990, 1989, and 2005) and various street space improvements. Significant interior renovations occurred in 2003, encompassing kitchen and room remodels on different floors, along with electrical upgrades for lighting and receptacles in both kitchen areas and a new basement bathroom installation.

However, the building has a concerning history of unauthorized unit modifications and space conversions, particularly regarding the garage area. Between 2002 and 2008, there were multiple complaints and violations regarding allegedly unauthorized construction of living spaces, including a garage conversion and basement modifications with unpermitted windows. These issues were officially abated, but the illegal unit behind the garage allegations appear in both complaint and violation records.

The building's plumbing and electrical systems have received attention, with documented work including sidewalk sewer pipe replacement in 2010. Recent maintenance records include a 2021 tree pruning request related to an overgrown tree near the property. The structure has undergone periodic exterior maintenance, including vinyl siding installation in 1988, and several street space and sidewalk repairs between 2008 and 2017, though these were relatively minor interventions. While many of the historical issues have been officially resolved, the pattern of unauthorized modifications and subsequent corrections raises questions about the building's maintenance history during that period.
