670-672 47th Ave, San Francisco, CA 94121

The property at 670-672 47th Avenue is a two-story, two-unit multi-family residential building constructed in 1960 and currently owned by the Wang Living Trust. The building has undergone several significant maintenance and repair projects over the past decades, with the most notable recent history centering around water damage issues. In 2019, multiple violations were recorded related to water damage, including problems with interior surfaces, mold/mildew, and fan repairs, which were all addressed by September 2021 through a comprehensive kitchen and bathroom remodeling project costing $30,000.

The building has received regular maintenance attention, including reroofing projects in 2005 and 2018 (costing $7,500 and $8,500 respectively), a window replacement and exterior improvements in 2009, and structural repairs like back staircase work in 2001 and dry rot remediation in 1990. More recent improvements include significant electrical upgrades in 2021, with the installation of a new 200A electrical service and laundry facilities, as well as plumbing modifications to accommodate washer machine installation. The property's recent history shows proper remediation of major issues, with the 2019 water damage incidents being fully resolved by late 2021, including the installation of new utility infrastructure.

Safety concerns were also addressed promptly, such as a blocked exit issue in 2021 that was corrected the same day. The building's maintenance record shows regular upkeep through various permits, though some historical issues like plumbing system repairs in 1989 and window upgrades in 2009 indicate ongoing attention to building preservation. Recent community reports through 311 calls have primarily focused on external issues like street cleaning, parking enforcement, and graffiti, rather than building-specific problems, suggesting the property is currently maintaining a stable condition. While there have been multiple instances of vehicles blocking driveways near the property (most recently in January 2024), these are external neighborhood issues rather than building-specific concerns.
