Boulder

Short-term rentals in the City of Boulder are strictly limited to an owner's primary residence. A biennial license and a safety inspection are required, and the city imposes a 7.5% Accommodation Tax on stays under 30 days.

To host an Airbnb in the City of Boulder, you must actually live in the home for most of the year—investment properties or second homes are generally not allowed for short-term rental. You will need to get a specific STR license which lasts for two years and pass a safety inspection (SmartRegs). Be sure to include your license number on your listing to avoid fines, and remember that even if Airbnb collects the 7.5% tax for you, you still have to file quarterly tax forms with the city.
