446-448 3rd Ave, San Francisco, CA 94118

The property at 446-448 3rd Avenue in San Francisco's Inner Richmond neighborhood is a two-unit, two-story multi-family residential building classified as a Flats & Duplex, built in 1914 and currently owned by the Shu Hung Lee Trust. The building's documented history shows several significant improvements, including the installation of a fire escape in 1986, foundation work to revise footings, and a horizontal extension project that converted one garage into two completed that same year.

A reroofing project was initiated in 1996 but the permit has since expired. Recent activity around the property has primarily involved street maintenance and parking enforcement issues. There have been multiple incidents of general street cleaning required in 2020, 2021, and 2023, including one instance involving hazardous materials (liquids) in 2021.

Driveway access has been a recurring concern, with two recorded instances of blocked driveways in July 2024 and July 2020, both resulting in enforcement actions. In 2014, there were two significant permit verification cases regarding driveway access and color curb requirements: one confirmed the presence of valid permits for driveway modification, and the other noted the existence of legally permitted red tips for the driveway. The building's structural and safety improvements, particularly the addition of a fire escape in 1986, appear to have been appropriately completed, though it's worth noting that the roof replacement initiated in 1996 remains listed as expired in the permit records.
