510 14th St, San Francisco, CA 94103

Located in the Mission Dolores neighborhood, 510 14th Street is a 1-story, 2-unit multi-family residential building constructed in 1906, currently owned by the Lee Family Trust. The building has undergone several significant events over the past decade, most notably in 2013 when serious concerns were raised about an allegedly illegal ground floor dwelling unit (unit 510), unauthorized renovation work, and multiple safety hazards including a collapsing deck, flaking lead paint, and an unsafe garbage storage situation.

This prompted official complaints and investigations by the Building Inspection Division, though these violations were eventually marked as "Not Active." In more recent years, the building has maintained compliance with no major violations on record, with two significant permitted improvements: a $28,800 reroofing project completed in 2022, and a $5,000 bathroom remodeling project in 2013 that addressed the aforementioned violations. The property has experienced recurring issues with sidewalk cleanliness and parking enforcement in the surrounding area, particularly between 2023 and 2025, with multiple documented cases of driveway blocking and reports of waste on public property.

While these external issues have been consistently addressed by city services, they represent ongoing challenges in the immediate vicinity of the property. The most recent infrastructure concern, filed in January 2024, involves a defect in the curb or curb ramp, which remains open and accepted for investigation.
