Which Colorado cities require a rental license?
There is no statewide rental license in Colorado. Every city decides for itself, the rules change, and two properties fifteen minutes apart can face completely different requirements. Here is how to work out what applies to yours.
The short answer
- Colorado has no statewide rental license. Requirements are set city by city and vary enormously.
- Denver and Boulder both require residential rental licenses with inspections. These are the two strictest in the region.
- Some cities require registration rather than licensing — cheaper and simpler, but still mandatory.
- Requirements are revised regularly. A rule that was true when you bought may not be true now.
- The reliable method is always the same: call the city and ask about long-term residential rental requirements for your specific address.
Owners routinely assume rental rules are set at the state level. They are not. Colorado leaves residential rental licensing almost entirely to municipalities, which means the requirement can change completely when you cross a street.
An owner with three properties — one in Denver, one in Westminster, one in Erie — may face three different obligations, three different renewal cycles and three different inspection regimes. Nobody sends a reminder.
The strict end: Denver and Boulder
Denver requires a residential rental license for long-term rentals, including single houses and condos, and the process includes a third-party inspection. See our full Denver rental license guide.
Boulder has required rental licenses for decades, enforces them actively, and layers occupancy limits on top. See our Boulder guide.
If you own in either city, assume you have an obligation and work backwards from there.
The middle: registration and targeted programs
Several metro cities sit between "nothing" and "full licensing." Common patterns include:
- Rental registration — the city wants to know the property is a rental and who to contact, without a full inspection regime.
- Complaint-driven inspection — no proactive requirement, but the city will inspect on complaint and can require remediation.
- Targeted programs — requirements that apply only to certain property types, certain zones, or properties above a unit count.
These are easy to miss precisely because they are low-friction. There is no inspector at the door, so an owner who never checked simply never finds out until something else brings the property to the city's attention.
Short-term rentals are a separate question entirely
Almost every city in the metro treats short-term rentals differently from long-term ones, and generally far more strictly — licensing, primary-residence requirements, caps on the number of permits, lodging taxes. If your property is or might become a short-term rental, research that separately. A long-term rental license does not cover it.
Own in more than one city?
Different rules, different renewal dates, different inspectors. We track all of it across the twenty cities we manage in.
How we handle multi-city complianceThe reliable way to find out
Do not rely on a forum post, a previous owner, or an article — including this one. Requirements change, and they change without much publicity.
Call the city's planning, licensing or community development department and ask a specific question: "I own a residential property at this address that I rent long-term. What licensing, registration or inspection requirements apply?" Ask them to point you at the ordinance. Then write down what they tell you and the date they told you.
Do this once per property, and again any time you hear that a city is revising its housing code. It takes twenty minutes and it is the cheapest compliance work available.
Why this is worth taking seriously
An unlicensed rental is not usually a catastrophe on its own — it is generally a fine and a scramble to get compliant. The real exposure is what it does to everything else. It weakens your position in an eviction. It surfaces during a sale or refinance. It gives a tenant's attorney something free to work with. And it tends to be discovered at the exact moment you least want a complication.
For the broader legal picture beyond licensing, our Colorado landlord-tenant law guide covers what applies statewide.
Short-term rentals are a separate regime entirely, and stricter — see short-term rental rules in Boulder County.
Frequently asked questions
Is there a statewide rental license in Colorado?
No. Colorado does not require a statewide residential rental license. Requirements are set by individual cities and counties and vary widely across the Denver metro.
Which Denver-area cities require rental licenses?
Denver and Boulder both have well-established residential rental licensing requirements with inspections. Other metro cities range from registration-only schemes to no requirement at all, and the rules are revised regularly. Check with each city directly for the current position at your address.
What is the difference between rental registration and a rental license?
Registration generally just records that the property is a rental and identifies a contact. Licensing usually adds an inspection against minimum housing standards, a fee, and a renewal cycle. Both are mandatory where they apply.
Do I need a separate license for a short-term rental?
Almost always yes. Short-term rentals are usually governed by a separate and stricter regime, often including a primary-residence requirement and lodging tax registration. A long-term rental license does not authorize short-term use.
How do I find out what my city requires?
Call the city's licensing, planning or community development department, describe the property and how it is rented, and ask what applies. Ask them to cite the ordinance so you can read it yourself, and note the date of the conversation.
