Thanks for the question. There are a ton of Hosts who do require additional contracts at time of check-in, copies of ID, collection of occupancy or value added taxes at check-in, etc etc. It is very clearly in policy that Airbnb allows this. Simply edit your listing ad and MAKE SURE to CLEARLY let it be known in the “house rules” section that per county regulations, you will be required to take a copy of their state issue ID or passport at time of check-in. No exceptions will be made.
Stating this in your listing is the only way Airbnb allows it and quite frankly, the only way to cover your own ass. A guest can call a CSR and bitch, scream, yell all they want and Airbnb will stand behind you 100% because it was known at the time of booking that you require it. The only time Airbnb will not be on your side in this matter is if the guest shows up and then is asked to provide ID, they say no, you say fine cancel, etc etc.
Biggest takeaway, the additional requirements need to be listed in House Rule section of your listing and then Airbnb will have your back on it and it is not breaking any policy. Sidenote: if you have any upcoming guests that you need ID for but havent added it to your house rules, shoot them a message and just let them know your county just changed rules and you’d like them to accept the new rule. If they give you any push back, either continue the reso and hopefully it slides under county radar, or call a CSR and tell them you’re uncomfortable with the upcoming guest and are requesting to cancel. NOTHING MORE NOTHING LESS> This type of cancellation is a cancel by admin or CBA and doesn’t count against you up to three times a year, so use the phrase only on much needed situations.
