128-130 Kingston St, San Francisco, CA 94110

The two-unit residential building at 128-130 Kingston Street in Bernal Heights is a 1909 flats/duplex structure owned by Christine C. Swanson. The building has experienced several significant maintenance and compliance issues over the past decade, most notably in 2019 when unauthorized construction of a wet bar and bathroom in the attic triggered multiple complaints and violations, though these violations were ultimately resolved by April 2022.

A series of roofing-related problems occurred between 2014-2017, including unauthorized work that led to violations and monitoring fees during roofing projects in 2014-2015, with complaints of late-night construction work that were also documented. The building has undergone several permitted improvements, including a roofing project completed in 2014 costing $4,800, safety-related work in 2019 to address water damage and compliance issues, and basement remodeling work permitted in 1990. Recent developments (2024-2025) have primarily involved street-level maintenance issues, including multiple reports of parked vehicles obstructing the sidewalk and recent calls regarding garbage and debris on the street, though these are external to the building itself.

The property has maintained active compliance with building codes since 2019, with no current building violations on record. A 2022 UDU screening determined that no Unauthorized Dwelling Unit was present on the property due to lack of distinct living space. The building's maintenance history shows a pattern of addressing violations through subsequent permits and compliance work, though some issues have required multiple interventions to resolve fully.
