Hi @Stacey604
Airbnb generally does not allow hosts to collect a separate security deposit directly from guests. There are some exceptions for hosts using API-connected software, where a security deposit may be permitted, but it must be clearly disclosed in the listing and house rules so guests are informed before booking.
If damage occurs during a stay, hosts typically have several options: they can request reimbursement directly from the guest through Airbnb’s Resolution Center, rely on AirCover for Hosts if eligible, or file a claim with their own home or rental insurance policy if applicable.
