957 Duncan St, San Francisco, CA 94131

The two-unit residential building at 957 Duncan Street in Diamond Heights is a single-story flats and duplex structure constructed in 1969, owned by Tim Quan and Terri M Woo. The building's maintenance history shows a significant issue from 2002-2003 when a roof leak was reported and subsequently addressed by Housing Inspection Services.

More recent records from 2023-2025 indicate ongoing maintenance concerns in the vicinity, particularly related to pavement conditions with active reports in October 2024 and November 2024. The property has experienced several infrastructure and maintenance issues in the surrounding area, including a resolved catch basin maintenance case in October 2024, though these are primarily external to the building itself.

The surrounding area has seen various municipal service calls, including three parking-related incidents in 2024 (including one for parking on the sidewalk that resulted in a citation), two abandoned vehicle reports, and other maintenance requests such as street cleaning and sidewalk defect reports. While most of these issues have been resolved or are being actively addressed by appropriate city departments, they appear to be more pertinent to the neighborhood infrastructure rather than the building itself. The only historical building-specific issue on record remains the roof leak from 2002-2003, which was resolved nearly two decades ago, suggesting that recent complaints have primarily concerned the immediate vicinity rather than the building's structural integrity or maintenance.
