Do You Need a Permit for a Short-Term or Mid-Term Rental in Colorado's Front Range?
If you've started researching whether to rent out your home short-term or mid-term, you've probably already hit the most confusing part of the process: permits. Unlike a lot of states, Colorado doesn't have one set of rules that applies everywhere. Every city along the Front Range - Denver, Arvada, Lakewood, Boulder, and Fort Collins, sets its own requirements, and they don't always agree with each other.
I get asked about this constantly, so here's the breakdown I wish someone had handed me when I started:
The big picture: it's not one set of rules
Short-term rental regulation in Colorado happens at the local level. That means the rules that apply to a home in Denver can look completely different from the rules for a home twenty minutes away in Arvada or Lakewood. If you own property in more than one of these cities, or you're trying to compare notes with another host, don't assume what worked for them will work for you.
Denver: the primary residence rule is the big one
If your property is in Denver, the single most important rule to understand is this: short-term rental licenses are generally tied to your primary residence. In plain terms, the city's short-term rental program is built around owner-occupied homes, not investment properties sitting empty while you list them on Airbnb.
Beyond that, Denver hosts typically need to:
Hold an active short-term rental license tied to the property
Carry liability insurance that meets the city's minimum coverage
Register for Denver's lodger's tax (separate from your STR license)
Display your license number on every listing
Check your HOA or condo documents, since an HOA can restrict or prohibit short-term rentals even if the city approves your license
Fees, exact insurance minimums, and renewal timelines change fairly often, so I'd rather point you to the city's official short-term rental licensing page for current numbers than publish something here that could be outdated by the time you read it.
Where mid-term rentals fit differently
Here's the part most STR-focused content skips entirely: mid-term rentals (typically defined as 30+ consecutive nights) usually fall outside short-term rental licensing requirements altogether, because most local STR ordinances specifically define "short-term" as stays under 30 days.
That doesn't mean mid-term rentals are unregulated. You're still subject to things like landlord-tenant law, lease requirements, and local business licensing depending on how your rental is structured. But it does mean that for owners who are running into primary-residence restrictions, zoning limits, or licensing caps on the short-term side, a mid-term strategy can sometimes be the cleaner path, or a smart complement to a short-term listing during parts of the year when short-term demand dips. This is one of the reasons I encourage owners to think about a hybrid approach instead of locking into one model before fully understanding how local rules apply to their specific property.
Outside of Denver: every county writes its own rules
Boulder, Arvada, Lakewood, Jefferson County, and Fort Collins each maintain their own licensing processes, zoning restrictions, and occupancy rules for short-term rentals. Some have primary-residence requirements similar to Denver's. Others are structured differently, with separate rules for owner-occupied versus non-owner-occupied properties. None of them are identical to each other.If you're evaluating a property outside Denver, the only safe move is to check that specific county’s current ordinance.
Why I handle this part for owners
Permits and licensing are the least exciting part of hosting, and also the part where a mistake is the most expensive. A misunderstanding about primary residence requirements, HOA restrictions, or licensing categories can mean fines, a forced delisting, or worse.
I track these requirements across every city I manage in. If you're not sure where your property stands, or whether a short-term, mid-term, or hybrid approach makes more sense given local rules, that's exactly what we cover in a free consultation.
