Guests of Airbnb rental properties in Detroit will not be allowed to host parties through the summer, the company announced Thursday.

Airbnb said Thursday it will require hosts to comply with enhanced cleaning procedures as part of its effort to reassure guests and local officials during the coronavirus pandemic. Hosts in China are exempt because have their own local cleaning program, the company said. Airbnb is no longer requiring hosts to leave their rentals vacant for at least 24 hours between guests, as it did in April. San Francisco-based Airbnb said nearly 1.5 million listings have signed on to the enhanced cleaning standards since they were introduced in June. The company has also been removing party houses from its platform after a shooting last year at an unauthorized Halloween party in California.
