173 20th Ave, San Francisco, CA 94121

The property at 173 20th Avenue is a two-story, two-unit multi-family residential building located in the Lake-Presidio neighborhood. Built in 1917 and currently owned by the Annie K Woo Trust, this flats and duplex structure has a minimal permit history, with only one recorded street space permit issued in June 2014 at a nominal cost of $1.00.

The building's maintenance and incident record over the past decade shows relatively few issues, with most concerns being external to the property. There were two reports of abandoned vehicles near the address - one in July 2013 involving a red Jeep that was gone upon inspection, and another in December 2018 where a vehicle had left by the time authorities arrived.

Street maintenance issues were reported through 311 calls, including a general cleaning request due to loose garbage in February 2021 that was resolved, and a public works service request related to blight in May 2014. The property's overall record suggests limited internal issues, with most reported incidents relating to street parking and public areas rather than the building itself.
