438-440 Campbell Ave, San Francisco, CA 94134

The two-unit residential building at 438-440 Campbell Avenue in Visitacion Valley is a 1908 two-story flats/duplex structure currently owned by the Sonny Nitin Vichare Revoc T trust. The property has undergone significant renovations, primarily in 2005, when a substantial $90,000 remodel was attempted, including updates to both units' kitchens, bathrooms, windows, electrical systems, heating, and landscaping. Multiple building violations were documented during this period (2005), including unauthorized construction work, plumbing modifications, foundation excavation, and unsafe electrical installations, though these violations were eventually abated by April 2007.

The building's systems have been maintained over the years, with water heaters replaced in 2015 and 2016, and various electrical upgrades including a 200-amp service upgrade in 2005. Recent activity shows some ongoing maintenance and compliance issues, particularly documented through 311 calls in 2024 regarding sidewalk obstructions, garbage, and debris. The property has experienced three fire-related incidents since 2009, though none resulted in injuries or significant damage, and most were found to have no merit.

The most recent violation was issued in October 2023 for weed and grass maintenance issues. The building's inspection history shows a pattern of unauthorized modifications and subsequent correction, typical of many older San Francisco properties, while recent maintenance records suggest more regular upkeep. The property owner had successfully resolved all major historical violations by 2007, demonstrating compliance with necessary building codes and regulations.
