Airbnb hosts are offering free housing for evacuees and emergency relief workers through Oct. 1st.

Airbnb is a home-sharing company, where ‘hosts’ rent their homes to others.

As of Thursday, more than 400 hosts in Atlanta and Augusta, Georgia; Charlotte and Greensboro, North Carolina; Columbia, Greenville and Spartanburg, South Carolina; and Charlottesville, Virginia have open their homes to those affected by Florence.

Evacuees or emergency workers can sign into the Airbnb app and navigate to the tab directing them to free shelter. They are asked to click a box confirming they have been affected by the storm. Airbnb said it will also waive its booking fees for those guests.

Anyone interested in opening their home can visit the Airbnb “Open Homes Program” website here.
