Which Colorado Cities Require a Rental License

There’s no statewide law requiring a rental license in Colorado — this is entirely a city-by-city question, and the answer ranges from “nothing at all” to “a license, a paid third-party inspection, and renewal every four years,” depending on where the property is.

Denver: mandatory license and inspection

Every residential rental property in Denver has to be licensed — this requirement fully phased in by 2024 and now covers all rental units, not just certain building types. Getting licensed requires passing an inspection from a qualified third-party inspector, and the license is good for four years before it has to be renewed with a new inspection. Fees are tiered by portfolio size — a single unit costs meaningfully less than a license covering dozens of units — plus a separate inspection cost paid to the inspector directly. Skipping this isn’t a minor paperwork gap; operating a Denver rental without a license is enforceable as a real violation, not just a technicality.

Boulder: license, inspection, and a local-agent rule

Boulder also requires a rental license for every property offered for rent, with inspections roughly every four years. One requirement that catches out-of-town owners specifically: if the property owner doesn’t live in Boulder County, the property needs a designated local agent who can respond in person within 60 minutes — a contact person, not just a phone number on file. Boulder also has a separate short-term rental license track (under 30 days) distinct from the standard long-term license.

Fort Collins: registration, not a full license

Fort Collins requires rental registration rather than a full license-and-inspection program — a lighter process, but still a real requirement, not optional. Fort Collins also enforces an occupancy cap (commonly cited as no more than 3 unrelated adults per dwelling) through its code compliance program, separate from the registration requirement itself.

Colorado Springs: nothing for long-term rentals

Colorado Springs does not currently require a license or registration for long-term rental properties at all — general property-maintenance and zoning codes still apply, but there’s no separate rental-specific licensing program. Colorado Springs does regulate short-term rentals (stays under 30 days) with their own license requirement, so the “no licensing” answer is specific to standard long-term rentals.

Why this matters even with a fully compliant lease

A lease can be completely compliant with every state-level requirement covered elsewhere on this site — deposit cap, fee rules, notice periods — and the property can still be operating illegally if it’s in Denver or Boulder without the required license. This isn’t a lease-clause issue at all; it’s a separate business-license requirement that exists alongside the lease.

What to check for your property

• Is the property in Denver or Boulder? If so, is there a current, unexpired rental license on file?
• If the license is due for renewal, is a new inspection scheduled with enough lead time?
• If you don’t live in the county where a Boulder property is located, do you have a designated local agent who can actually respond within the required window?
• Is the property in Fort Collins? If so, is it registered, and does occupancy stay within the local cap?

The bottom line

Local licensing rules change independently of state law and vary sharply by city — always confirm current requirements with the specific city’s licensing office before assuming last year’s answer still holds. This falls outside what a lease-template compliance check covers, but it’s worth confirming alongside it if your property is in one of these cities.
