340 Duncan St, San Francisco, CA 94131
340 Duncan Street is a two-unit, two-story multi-family residential building located in San Francisco's Noe Valley neighborhood, owned by the Careway Family Revocable Living Trust. Built in 1890, this flats and duplex-style building has undergone several significant renovations, with the most substantial work occurring between 2002-2003.
During this period, a comprehensive $75,000 renovation project was completed to construct a new 3-car garage with stairs, an exit corridor, and electrical and plumbing updates, followed by additional structural improvements including the replacement of a glu-lam header and installation of steel frames. The building underwent window-related improvements in 2003, involving the replacement of nine windows, repair of dry rot, and associated patching and painting work totaling $22,000. The property has seen various maintenance and upgrade work over the years, including two kitchen remodels in the late 1980s, installation of new furnaces and ducts in 2008, and some street space permitting in 2008.
A garage modification project in the rear yard with a roof deck and stairs was also approved, demonstrating the property's ongoing development history. The only recorded parking-related complaint was in 2018 regarding a blocked driveway, but this case was deemed invalid due to incomplete reporting information. The building's maintenance and improvement history suggests regular upkeep and modernization efforts by the ownership, with no documented safety concerns or habitability issues on record.
