470-472 11th Ave, San Francisco, CA 94118

The three-unit multi-family residential building at 470-472 11th Avenue in San Francisco's Inner Richmond neighborhood, owned by Sung Ping Jso, has undergone significant improvements and modifications since its construction in 1913. Most notably, between 2015 and 2018, the property underwent extensive renovations including a major remodeling project in 2015 that encompassed four bathrooms, six bedrooms, two kitchens, and multiple living spaces across the first and second floors, with comprehensive electrical and plumbing upgrades.

The building's safety systems were significantly enhanced in 2017-2018, with the installation of fire sprinklers on the ground floor, followed by the addition of a fire alarm communication unit to monitor the sprinkler system, complying with San Francisco Fire Department requirements. The property has a documented history of addressing safety and maintenance concerns, including a fire safety inspection in 2017 that noted the presence of combustible materials (though this complaint was ultimately found to have no merit). The building's infrastructure has received regular attention, with significant work completed on the electrical system in 2015 including new panelboards, lighting, and smoke detectors, as well as plumbing upgrades including bathroom and kitchen remodels.

Older maintenance records show attention to basic upkeep, including dry rot repairs to the rear deck/stair in 1998 and a roof replacement in 1997. While there have been multiple documented issues with the sidewalk in front of the property between 2012 and 2015, these were addressed through inspections and notice of temporary repairs, along with some tree root-related damage that required attention. The most recent documented issues have been parking-related complaints in 2022, which were handled through standard enforcement channels.
