This is the general rule for Thornton. Does your address qualify?

The free info covers the city as a whole. Your property can still be different: zoning can change from one street to the next, and an HOA or condo ban can stop rentals even where the city allows them.

Your $49 Compliance Check looks at your exact property:

Whether your exact address and zone allow short-term rentals
A check of HOA / condo rental restrictions to look for
Which permits and tax accounts you personally need
What you're missing right now
A personal report with clear next steps and official sources, by email
A refund if we report a rule in error (refund policy)

Taxes & who collects them

Register / account for City lodging tax (7%)
What Airbnb collects: Verify in payouts which taxes your platform remits.
Vrbo and direct bookings: check which taxes Vrbo collects in your area; for direct bookings you collect and remit all of them yourself.

Total rate: 7%. Collect and remit the 7% city lodging tax (instead of city sales tax) at least quarterly; platforms do not remit it for you. Calculate.

HOA / condo check

Read your declaration, bylaws and rules for rental bans, minimum terms, caps and approval requirements.
Get any association sign-off or approval letter your city or association requires.
See our HOA & condo guide.

Insurance

Confirm your homeowner/condo policy covers short-term rental use, or add a short-term rental policy. Platform host protection is not a substitute for insurance.
Ask your association whether it requires specific liability coverage.

Deadlines

Renew city/county permits or registrations on their schedule (often annually): confirm the date with the office that issued it.
File state and local lodging tax returns on the schedule your tax office assigns.
