As @Anonymous said, this is not a fee that airbnb supports. The onus is on you to try and collect it. Also, hosts have found that a high percentage of guests don’t even read the house rules. So, in addition to the house rules in my listing, and the house rules located in the STR, I also ask guest to agree to house rules if it’s an IB or a request for approval during booking. Then at check-in, I give a 5-10 minute tour and go over the house rules again.
@Yaisa0 When a house rule is broken, it’s up to the host to intervene immediately through airbnb’s messaging portal, reminding guest of your house rules and letting guest know that you will cancel the reservation if the behavior continues.
