2331-2333 Bush St, San Francisco, CA 94115

The two-unit residential building at 2331-2333 Bush Street in Lower Pacific Heights, owned by the Bolaffi Family Trust, is a two-story flats and duplex structure built in 1904. The building has experienced recurring issues with dry rot and structural maintenance needs, particularly in its early years, with several documented repairs between 1997-2003 addressing problems with the rear deck, stairs, and kitchen.

A significant incident occurred in 2006 when excavation work at a neighboring property undermined the building's east foundation wall, resulting in emergency stabilization work that October and subsequent building violations, though these were resolved by October 2006. The property underwent kitchen improvements in 2003-2004, including electrical work, and had some exterior maintenance issues in 2006-2007, including concerns about lead paint and antenna encroachment, all of which were subsequently addressed.

More recent history shows an active parking enforcement environment, with numerous complaints about driveway blocking documented between 2024 and 2025, though many of these cases were either unable to verify the violation or required additional reporting information. A single fire-related incident was recorded in 2019 involving a malfunctioning smoke detector, with no injuries reported. The building's maintenance history shows regular upkeep, with the most significant structural challenges appearing to have been addressed through proper permitting and remediation.
