476-478 3rd Ave, San Francisco, CA 94118

The two-unit residential building at 476-478 3rd Avenue in San Francisco's Inner Richmond neighborhood is a 2-story flats and duplex structure built in 1904 and currently owned by Stanley Albertine M Living Trust. The property has undergone several significant improvements and maintenance projects over the past decade.

Most recently, in September 2024, permits were issued for installation of seven front-facing double-hung windows and two custom doors, featuring energy-efficient Marvin aluminum clad construction (valued at $13,000), while earlier that month the building completed a $25,000 re-roofing project. In 2018, the property underwent exterior improvements with a $20,000 siding replacement project, which was particularly notable as the building is classified as a Category B historic resource, with the work being not visible from the street.

Historical records indicate some structural maintenance was performed in 1996, addressing issues with the rear stairway and replacing rotted joists, though this permit has since expired. The only recorded 311 call related to this address was in November 2019 regarding a sidewalk parking violation, which was resolved by parking enforcement.
