3 Sonoma St, San Francisco, CA 94133

The three-unit, three-story apartment building at 3 Sonoma Street, owned by the Kwong Family Trust and located in Telegraph Hill, has been standing since 1909. The property has experienced several significant plumbing issues in recent years, most notably a series of sewage backup incidents in August 2021 that required multiple interventions by PUC Sewer Operations over several days, including inspections, plunging, flushing, and CCTV investigations.

A street space permit was issued in July 2017, though the cost was listed as $0.00. The building's exterior and surrounding areas have been subject to various maintenance and sanitation concerns, with multiple 311 calls regarding street cleaning and waste accumulation.

Notable incidents include a report of cans being left out continuously in August 2008, lifted sidewalk issues documented in August 2011 involving downed signs and bollards, and several street cleaning requests in July 2017 and January 2018. More recent external maintenance issues were reported in October 2020, though specific details were not elaborated in the record. A single hygiene-related incident involving human or animal waste was reported and resolved in January 2023 on the street near the property.
