14-16 Sonoma St, San Francisco, CA 94133

The two-unit residential building at 14-16 Sonoma St in Telegraph Hill, owned by the Grassini Living Trust, is a two-story flats and duplex structure built in 1912. The building's maintenance history shows relatively minimal documented work, with only one recorded permit for reroofing work from 1998, which has since expired.

The property's most recent significant infrastructure issue occurred in November 2023, when a sewage backup incident involving a 4-inch sewer vent was reported and subsequently resolved by the PUC Sewer Operations team. This recent incident marks the third documented sewage-related problem in the building's history, following a similar event in October 2009. The property has experienced recurring issues with street cleanliness and waste management in the vicinity, particularly between 2008 and 2020, including multiple reports of loose garbage (2011, 2017, and 2020) and improper waste container management (cans left out continuously in 2008).

A hazardous materials incident involving glass was reported in May 2011, though specific details require further review in the notes. The building's parking-related complaints have been minimal, with only one documented case in February 2019 regarding a blocking vehicle, though the responding officer was unable to locate the vehicle in question. While the property's basic infrastructure appears to function adequately, the recurring sewer issues and periodic cleanliness concerns suggest ongoing maintenance challenges in both the building and its immediate surroundings.
