Northglenn FAQ
Does Adams County require a short-term rental license fee?
Unincorporated Adams County does not currently publish a dedicated short-term rental licensing fee in the Development Standards and Regulations, unlike many Colorado mountain counties. Operators still need a Colorado Department of Revenue sales-tax license and must collect state and county sales and lodging tax. If you live inside Brighton, Commerce City, Westminster, or another Adams County city, that municipality's STR rules and fees apply instead. Confirm current requirements with the Adams County Community & Economic Development Department at 720-523-6800.
What sales and lodging taxes apply to an Adams County Airbnb?
Stays under 30 consecutive days are taxable lodging in Colorado. Operators must register with the Colorado Department of Revenue and collect 2.9% state sales tax plus 0.75% Adams County sales tax. Adams County also levies a local lodging (accommodations) tax on short-term stays. Confirm the current lodging-tax rate, filing frequency, and any special-district add-ons with the Adams County Finance Department at 720-523-6051 before setting nightly prices.
Do I have to display a license number on my Airbnb listing?
Yes. Colorado House Bill 23-1287, signed in 2023, requires short-term rental operators to display their state sales-tax license number on platform listings such as Airbnb and Vrbo, and clarifies counties' authority to license and regulate STRs. Even though Adams County does not currently issue its own STR license, the state DOR sales-tax account number must still appear on listings and in remittances.
