2260-2264 Union St, San Francisco, CA 94123

The property at 2260-2264 Union Street in Cow Hollow is a two-story, three-unit multi-family residential building owned by Giampaolo Boschetti, constructed in 1909. The building has undergone several significant events over its history, most notably a series of violations identified in November 2005 related to fire safety, interior surfaces, and sanitation issues. These violations included problems with fire proofing, damaged doors, floor coverings, walls/ceilings, egress obstructions, and sanitation concerns, all of which were officially abated by December 21, 2009.

A separate incident from 1983 involved small fire damage to the basement and blind wall, though records show no injuries were reported. In recent years, the building has experienced various maintenance issues typical of urban properties, as evidenced by multiple 311 calls. Between 2021 and 2025, there have been reports of sidewalk graffiti (both public and private), street cleaning needs, parking violations, and a defaced parking sign.

Two driveway blocking incidents occurred in 2023, resulting in citations being issued. The most recent graffiti incident from January 2025 remains open, while a February 2022 encampment issue near the property was resolved. The building's maintenance history shows regular attention to addressing violations when they occur, with significant improvements made following the 2005 violations and a completed termite treatment in 2009.
