1938-1940 19th Ave, San Francisco, CA 94116

Located in San Francisco's Inner Parkside neighborhood, this 2-unit duplex was built in 1945 and is currently owned by Mike Wen Hu Yao and Lin Yingx. The two-story multi-family residential building has a notable history of permit activity and compliance issues. Most significantly, in March 2008, the building received a violation for constructing an illegal third unit in the garage level, along with unauthorized stucco work at the front garage area.

These issues were addressed through a completed permit in 2008 that required the illegal kitchen removal and garage stucco repairs, with the violation ultimately being abated in March 2010. The building has undergone several permitted improvements over the years, including a substantial renovation in 2002 that added a storage room, study room, and bathroom to the ground floor, along with associated electrical work. The second floor received kitchen remodeling in 2008, which was properly permitted and included electrical upgrades.

Prior maintenance work included a roofing project from 2000 and vinyl siding installation in 1989, though these permits eventually expired. A recent street space permit was issued in September 2013, but no significant violations or complaints have been recorded in the past decade, suggesting a period of relative compliance. The building's permit history demonstrates a pattern of addressing unauthorized modifications through proper channels, most notably the 2008 violations that were ultimately resolved through permitted repairs and remediations.
