580-582 Corbett Ave, San Francisco, CA 94114

The two-unit residential building at 580-582 Corbett Avenue in Twin Peaks is a single-story flats/duplex structure built in 1959 and currently owned by the Ng-Tang Family Trust. The property has undergone several significant renovations over the past decade, with the most recent work being a complete bathroom remodel in unit 582 in 2020 ($44,000), which included electrical upgrades such as exhaust fans and recessed lighting.

In 2017, both units received kitchen updates including new cabinets, countertops, appliances, and electrical systems ($42,000), with subsequent structural revisions to install a new recessed beam in the kitchen. Additional improvements include a Level 2 EV charger installation in 2018, underground service conversion and 200A upgrade in 2004, and a reroofing project completed in 1990. The building has experienced some infrastructure challenges, including a sewer backup incident in November 2017 and multiple sewer line permit applications in October-November 2017, though these issues do not appear to have persisted.

A construction-related complaint was filed in July 2020 regarding work exceeding permit scope and construction noise, though this complaint is currently listed as not active. The property has experienced recurring issues with driveway blocking, with three incidents reported between 2019-2023, though enforcement officers were typically unable to locate the offending vehicles. A 2013 tree-related issue was resolved through replanting, and a 2010 building inspection complaint was assigned to Inspector Schroeder for follow-up.
