Frequently Asked Questions
Can I place a tiny home on my property in O’Fallon?

Can I use it as an Airbnb?
Yes, O’Fallon’s proximity to St. Louis, hospitals, and family events drives strong short-term rental demand, but obtain a city business license and comply with occupancy limits. Park Models work best for guests, boosting income in this growing suburb.
