City STR rules not reflected in Airbnb listings

[Dalton Clem]

Hello, 

This is in regards to residential zoning. The town I live in (WISCONSIN DELLS) has STR rules which require no less than 7 days but no more than 29 days for STR. When I check Airbnb listings they show listings that can be booked for a day or so, which are not the towns rules. I am considering doing STR on my property in the future but want to abide by the rules and stay on good terms with the town. Are these listings breaking the rules or is there something I am not aware of. I have contacted the city twice for clarification but gotten an "out of office" message both times and never gotten a reply when they were suppose to be back in the office.
