266-268 15th Ave, San Francisco, CA 94118

The two-unit residential building at 266-268 15th Avenue in the Central Richmond neighborhood is a two-story flats and duplex structure, built in 1905 and currently owned by Herbert W & Karen L Choy 20. The property has undergone some significant maintenance work in recent years, most notably in May 2016 when permeation grouting was performed beneath the foundation on the rear north side, covering an area of approximately 27 linear feet at a cost of $4,500 - this work was completed successfully.

The building's service history includes several maintenance and enforcement issues between 2018 and 2024. A sewage backup incident occurred in August 2021 involving a 4-inch sewer vent, which was promptly addressed and resolved by PUC Sewer Operations.

The property has experienced recurring issues with blocked driveway access, with three documented incidents in 2018 involving vehicles ranging from a Ford to a Toyota Yaris and a Chevy Express; citations were issued in at least one of these cases. More recently, in September 2024, there is an open case regarding an overgrown tree reported to Public Works Street and Environmental Services. While the parking-related issues and the sewer incident are noteworthy, the most significant structural maintenance on record remains the 2016 foundation work, which demonstrates proactive maintenance of the building's infrastructure.
