There was a recent fire in a summer vacation town popular with NYers. The town requires summer short term rental landlords to get a permit & inspection. The landlord did not get one. The landlord also had sketchy kitchen wiring that was probably some sort of DIY and not up to code. The landlord had removed batteries and hardwiring from 3 smoke detectors. These are the kind of things the inspector would have found immediately.
A family visiting from out of state lost 2 of their 3 children in this fire.
Apps like AirBnB create the facade of officialness on what are instead very sketchy markets. Family probably thought they were doing the right thing going through an app and the landlord must be verified and more "legit". Being from out of state they wouldn't know the intricacies of local town permit&inspection requirements and how to check if the landlord has one, etc.
Likewise in my condo in NYC, we had one particular owner who was trying to use their unit as an Airbnb. Regardless of the local laws which were tightening up at the time, our condo expressly forbid short term rentals, and had language around minimum length of stay and lease approval requirements. It only stopped when we started fining them $1000 per incident.
Stuff like this matters because you buy a condo to live in it and don't expect the unit on the other side of your bedroom wall to essentially be a hotel room with new neighbors every 3 days, staying up all hours (vacation, yay), dragging suitcases in&out at odd hours multiple times per week.. forever.
The building itself takes on a lot more wear & tear, and they put a burden on staff as they think the building porter&doorman are there for them like a hotel concierge and front desk.
