1661 Filbert St, San Francisco, CA 94123

The two-unit residential building at 1661 Filbert Street in the Cow Hollow neighborhood is a two-story structure classified as a Flats & Duplex, built in 1948 and currently owned by the Belloni Marital Trust.

The building's documented history reveals relatively minimal issues, with only one significant building permit on record from December 2012 for a re-roofing project valued at $8,300, which has been properly completed. The property has had routine urban maintenance matters reported through the 311 system, including a street cleaning issue in October 2023 involving loose garbage (which was investigated but nothing was found), a defaced parking sign in May 2019 that was resolved, and an abandoned vehicle report in July 2012 where the vehicle was gone upon inspection.

A notable administrative matter was resolved in January 2022 when the Rent Board updated the property's records to correctly reflect its two-unit status following a customer callback request. While the building's record shows regular city maintenance interactions, there are no recorded safety incidents or significant building concerns, and no recent major renovations or permits besides the 2012 roofing work.
