Is there a cost for replacing the lost parking pass and do you charge a deposit?
If you know the cost and have a damage deposit, I would put in your description about parking that there is a $$$ charge for having to replace a missing parking pass. If someone does lose the parking pass, you will have to provide a proof of the replacement cost to Airbnb as part of your claim.
For example:
"Parking Permit is required in most areas. Will provide one guest parking permit ($40 replacement fee if lost). Free parking in front of the house and in other areas without permit (see parking map provided upon checkin). Be sure to read all parking signs to avoid $80 ticket."
