1326-1328 16th Ave, San Francisco, CA 94122

The two-unit residential building at 1326-1328 16th Avenue in San Francisco's Inner Sunset neighborhood, owned by Zhao Liang & Xiao H, is a two-story flats and duplex structure built in 1925. The building has a significant history of unauthorized modifications and occupancy issues, particularly evident in a series of complaints filed in 1998-1999 regarding illegal units and overcrowding, with one complaint alleging 16 occupants in total.

These complaints led to the successful legalization in 1999 of an existing living area behind the garage that included storage, bedroom, laundry, and bathroom facilities, though this was not without controversy. The building has undergone various legitimate improvements over the years, including a kitchen remodeling project in 1994 (though this permit expired), reroofing in 1993, and efforts in 1990 to bring the building up to code.

More recent history shows no major building permit activity or complaints about illegal units, suggesting improved compliance with housing codes. The property's recent maintenance record includes two minor incidents: a 2022 report of loose garbage that was investigated but found to have no issues, and a 2018 sidewalk parking violation that was resolved through police intervention. While the building's past includes numerous code compliance and occupancy challenges, recent history indicates no similar problems have been reported.
