476-478 Corbett Ave, San Francisco, CA 94114
The duplex at 476-478 Corbett Avenue, located in the Clarendon Heights neighborhood, is a two-story multi-family residential building constructed in 1948 and currently owned by Andreas J & Mary Mourelatos. The property has undergone several significant maintenance and infrastructure improvements over the years, including a 2013 complete replacement of the house trap, installation of underground electrical service in 2005, and multiple plumbing upgrades.
Of particular note is a substantial cluster of building violations filed in April 2000, which included issues with windows, stairs, insulation, and fire safety concerns, though all violations were officially abated by February 2002. The building's maintenance history shows attention to window and exterior upkeep, with permits for vinyl windows and siding installation in 2000, and a stair repair in 1995. Recent records indicate several infrastructure issues, particularly in the years 2013-2014, including multiple sewage backup incidents that required professional intervention and coordination between the owner and city services.
The property has also experienced some exterior maintenance challenges more recently, with a collapsed sidewalk reported in 2022. All known violations and complaints have been resolved according to official records, with the most recent building-related service calls being for utility billing matters in 2024. The building's unit configuration remains as originally built, with two separate residential units under the flats/duplex classification.
