Colorado Contractor License Bonds
Colorado contractors do not answer to a state licensing board. DORA does not issue contractor licenses. Instead, every city sets its own rules. A Front Range contractor working Denver, Aurora, and Colorado Springs carries three separate bonds to three separate building departments. This guide explains the municipal patchwork and how to navigate it efficiently. Start with what a surety bond is if you are new to bonding.
One application covers bonds for every Colorado municipality -- we handle the multi-city paperwork so you do not have to.

The Front Range Problem: Why Colorado Contractors Carry 3-4 Bonds at Once
In California, you get one state bond and work anywhere. In Colorado, a contractor who takes jobs in Denver, Aurora, and Colorado Springs needs separate registrations and separate bonds in each city. Miss one and you face stop-work orders, fines up to $999/day in Denver, and permit revocations. The bond vs. insurance distinction matters here: your general liability covers damages, but each city's bond guarantees you follow that city's building codes.
Common Mistakes
- Assuming one bond covers all cities

- Starting work before municipal registration
- Missing different renewal dates per city

Working Across the Front Range?
Contractors working in multiple Colorado cities need separate bonds for each jurisdiction. We can issue all of your municipal bonds under a single application -- Denver, Aurora, Colorado Springs, and beyond. Colorado businesses that sell vehicles will also need a separate Colorado auto dealer bond from the DMV.

Five Steps to a Colorado Contractor License
Since there is no state license, the process is city-by-city
- 1
Identify your work area
Determine which Colorado municipalities you will operate in. Each city has independent licensing requirements.
- 2
Check local requirements
Contact the building department in each city. Ask about license classifications, bond amounts, insurance minimums, and exam requirements.
- 3
Purchase your bond(s)
Buy a surety bond for each city. Denver requires $10,000-$50,000 depending on trade. Smaller cities typically require $5,000-$25,000. Read the full process at /how-to-get-a-surety-bond/.
- 4
Apply for the municipal license
Submit your application with bond, proof of insurance, and license fee. Denver charges $250 for a 3-year license.
- 5
Maintain and renew
Keep your bond active throughout the license period. Renew before expiration to avoid work stoppages.

Does Colorado require a state contractor license bond?
No. Colorado has no statewide contractor license or bond requirement. The Colorado Department of Regulatory Agencies (DORA) does not issue a general contractor license. Instead, individual municipalities and counties set their own licensing and bonding rules. Denver requires bonds ranging from $10,000 to $50,000 depending on trade type. If you work in multiple cities, you may need separate bonds for each jurisdiction.
Which Colorado cities require contractor bonds?
Major cities requiring contractor bonds include Denver ($10K-$50K by trade), Colorado Springs ($5K-$15K), Aurora ($5K-$25K), Fort Collins, Boulder, Lakewood, and Thornton. Each municipality sets its own bond amounts and renewal schedules. Denver has the most detailed requirements, with separate bonds for general, sewer, paving, structural, and sidewalk contractors. Always confirm with the local building department before starting work.
What is the Colorado Little Miller Act?
The Colorado Little Miller Act (C.R.S. Section 38-26-106) requires performance and payment bonds on public works projects exceeding $50,000. These are separate from municipal license bonds. The performance bond guarantees project completion, while the payment bond ensures subcontractors and suppliers are paid. Bonds are typically 100% of contract value. This mirrors the federal Miller Act for state-level government projects.
Do I need separate bonds for each Colorado city?
Yes. Because Colorado has no state license, each municipality operates independently. If you work in Denver and Aurora, you need separate bonds for each city. Some contractors working across the Front Range maintain three or four municipal bonds simultaneously. We can issue all of them under a single application, simplifying your paperwork and often reducing overall costs.
How long does it take to get a Colorado contractor bond?
Most Colorado municipal contractor bonds can be issued within 24 hours for applicants with good credit. Bonds are delivered electronically for immediate filing with your local building department. Denver contractor licenses are valid for three years once issued. Other cities may have annual or biennial renewal schedules.
