662-664 22nd Ave, San Francisco, CA 94121

The property at 662-664 22nd Avenue is a two-story, two-unit multi-family residential building located in the Central Richmond neighborhood, constructed in 1918 and currently owned by Ki Young & Sook Hee Han 200. The building has undergone several significant maintenance and improvement projects over the years, including a complete reroofing in 2009 costing $10,700, and a vertical addition was completed in 1989.

More recently, in May 2019, both the sewer line/house trap system was replaced and street space work was performed, though these improvements were preceded by a concerning plumbing violation regarding fresh air inlet issues and house trap installation that remains active as of now. The building's recent history shows some maintenance activity but also some pressing infrastructure concerns that have not yet been resolved.

The active plumbing violation from April 2019 indicates problems with the fresh air inlet system that were serious enough to require a violation notice, and though there have been subsequent sewer line improvements, the original concern appears to have persisted. The property has experienced relatively few complaints over the years, with only one notable incident in 2017 involving structural concerns due to excessive loading, which is noted as not active. The most recent municipal interaction was a street cleaning matter reported in December 2023 regarding loose garbage, which remains open as of now.
