Augrented Insights Report

The two-unit residential building at 1357-1359 Mason Street in Nob Hill, owned by Gene W Y and Flora H Yee, is a two-story flats and duplex structure built in 1923.

The property has experienced recurring parking-related issues between 2021 and 2022, with multiple incidents of driveway blocking and sidewalk parking, particularly involving a gold Toyota 4Runner, though enforcement responses resulted in either citations or officers being unable to locate the offending vehicles. There were also service requests related to street cleaning, including missed trash collection in November 2024 and other loose garbage in August 2022.

Two fire incidents have been recorded at the property, including a cooking fire that was confined to a container with no civilian injuries and an unintentional alarm system activation, both showing no injuries or significant damage. The building's maintenance and incident history suggests regular enforcement response to parking violations and prompt resolution of sanitation issues, with no major safety concerns reported through the fire incident records.
