3215 Balboa St, San Francisco, CA 94121

The two-unit residential building at 3215 Balboa Street in San Francisco's Outer Richmond neighborhood is a two-story, flats and duplex structure built in 1944, currently owned by Chow Wan Koon.

The property has undergone several significant modifications and maintenance work over the past few decades, with the most recent major building activity being a street cleaning incident in May 2020 and a sewage backup resolution in November 2018. The building's history includes a noteworthy compliance issue in 1999 when a complaint was filed regarding a possible illegal unit with improper wiring to the main meter, though this matter was resolved by April 2002, followed by the removal of an illegal basement conversion in June 2000, which was subsequently modified into a playroom and guestroom.

Other permitted improvements include a change to the lower floor plan with the addition of a hallway from the garage to the rear in December 2000 and a complete reroofing project completed in 2004, demonstrating regular maintenance of the building's infrastructure. While the building has experienced some maintenance issues, including a sewer vent problem in 2018, all reported incidents have been resolved through proper channels.
