Airbnb said recently 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.

The home-sharing company said hosts have until Nov. 20 to commit to the cleaning protocols, which include scrubbing floors and other surfaces with soap and water; washing linens on high heat; disinfecting high-touch items like doorknobs; and ventilating rooms. Hosts who don’t comply may be suspended or removed from Airbnb.

Airbnb is no longer requiring hosts to leave their rentals vacant for at least 24 hours between guests, as it did in April. But it does suggest a 24-hour waiting period, and is telling hosts to consult their local governments for requirements.

San Francisco-based Airbnb said nearly 1.5 million listings have signed on to the enhanced cleaning standards since they were introduced in June. But that’s only a fraction of the company’s 7 million listings.

The company also said Thursday that guests and hosts must wear masks and social distance when interacting with each other.
