The owners of apartment buildings in San Francisco’s Tenderloin neighborhood are suing the city and county of San Francisco for treating the working-class neighborhood as a “containment zone” for its drug and homelessness issues, creating unsanitary and unsafe conditions that have worsened during the coronavirus pandemic.

The complaint, filed in the U.S. District Court for the Northern District of California on Friday, follows a similar lawsuit brought by a group of Tenderloin businesses, as well as the University of California, Hastings College of the Law.
