15-17 Nantucket Ave, San Francisco, CA 94112

The two-unit residential building at 15-17 Nantucket Avenue in Mission Terrace, owned by Lee Kwok-wing, has undergone several significant changes since its construction in 1961. In 2005, substantial modifications were made to the property, including the addition of a bedroom, storage room, full bathroom, and family room on the ground floor, along with a comprehensive electrical system upgrade to 200-amp service with multiple meters, panels, and new wiring installations, with these improvements totaling approximately $56,000. The building's maintenance record shows earlier care with a reroofing project completed in 1991.

The property has experienced numerous service calls and incidents in recent months, with the most notable being a sewage backup discharge from a side sewer vent in October 2024. There has been a concerning pattern of parking violations in the vicinity, with eight reported incidents between August and November 2024, though many could not be validated or resulted in no enforcement action. Several environmental issues have been reported, including two instances of garbage and debris on public property in late 2024, one of which involved accident debris.

The building has also faced some structural challenges, as evidenced by a property damage report related to tree maintenance in September 2024. While these incidents primarily involve the surrounding area rather than the building itself, they may impact resident quality of life. It's worth noting that there was a tenant buyout at the owner's other property (30 Paulding Street) in 2020, though this is unrelated to the current building.
