How to get licensed as a contractor in Colorado
Colorado has no statewide general contractor license. The state licenses exactly two trades, electrical and plumbing, through boards in the Department of Regulatory Agencies, and leaves general contractors, HVAC, roofing, and everything else to cities and counties. That means a Denver GC license does not work in Colorado Springs, and the real question is which jurisdictions you pull permits in.

When a license is required
There is no state dollar threshold because there is no state general contractor license. Electrical and plumbing work requires a state license at any dollar amount, in every city and county. For all other work, licensing requirements and thresholds are set by the local jurisdiction where the project sits.
License classes in Colorado
Electrical licenses
Issued by the State Electrical Board through DORA at residential wireman, journeyman, and master levels, plus electrical contractor registration for the business itself.
Plumbing licenses
Issued by the State Plumbing Board at residential, journeyworker, and master levels, with a plumbing contractor registration tied to a responsible master plumber.
Local general contractor licenses
Cities and counties license GCs on their own terms. Front Range cities commonly classify licenses by building type and size and often ask for ICC exam results, insurance, and experience documentation.
Local specialty licenses
Roofing, HVAC, and other trades are licensed city by city. Requirements genuinely differ across municipal lines, so verify before bidding outside your home turf.
What you need before you apply
- For electrical or plumbing: qualifying experience hours and a passing state exam for your level
- For electrical or plumbing businesses: a contractor registration tied to a licensed master
- For GC work: whatever the permitting jurisdiction requires, commonly insurance certificates, experience, and an exam
- General liability insurance at the limits your jurisdictions demand
- Workers compensation coverage for employees, required statewide
- A registered business entity with the Colorado Secretary of State
How to get licensed in Colorado
- List where you will actually work. Licensing lives at the city and county level, so write down every jurisdiction where you expect to pull permits in the next year. That list defines your licensing plan.
- Handle the state trades first if they apply. Electrical and plumbing work requires a DORA license before any local step. Apprenticeship hours, exam, then contractor registration for the business.
- Apply to each local building department. Submit each city's contractor application with insurance, experience, and exam documentation. Many Front Range jurisdictions accept ICC exam results, which travel better than a city-specific test.
- Track renewals per jurisdiction. Each license renews on its own schedule with its own fee. A calendar of renewal dates prevents the classic mistake of pulling a permit on a lapsed license.
Reciprocity with other states
There is no general contractor reciprocity because there is no state GC license; every jurisdiction decides for itself, though many accept the same ICC exams. The state electrical and plumbing boards evaluate out-of-state credentials and experience case by case, so licensed trade workers moving to Colorado should apply through DORA with their history documented.
Working without a license
Doing electrical or plumbing work without a state license draws fines from the state boards. For everything else, enforcement is local: stop-work orders, permit denial, municipal fines, and trouble getting future permits in that jurisdiction. Confirm each city's current rules with its building department, because they change without much notice.
Frequently asked questions
Does Colorado have a state general contractor license?
No. Colorado licenses only electricians and plumbers at the state level, through DORA boards. General contractors are licensed by cities and counties, each with its own application, exam preferences, and insurance minimums.
I have a Denver GC license. Can I build in Aurora or Boulder?
Not automatically. Each jurisdiction issues its own license, though many accept the same ICC exam results, which cuts the retesting burden. Apply to each city where you will pull permits and keep each renewal current.
Do handymen need a license in Colorado?
Not from the state, unless the work is electrical or plumbing, which always requires a state license. Local rules control everything else, and some cities require a license or registration for even small permitted work. Check the building department where the job sits.
What insurance do Colorado contractors need?
Workers compensation is required statewide for anyone with employees. General liability limits are set by each licensing jurisdiction, and most cities want a certificate naming them before issuing a license. Carry limits that satisfy the strictest city on your list so one policy covers everywhere you work.
How do multi-city Colorado contractors keep their office work straight?
Working across several jurisdictions multiplies the admin, and the office usually rides shotgun in the truck. Staxen's AI employees draft estimates from a voice note, invoice with payment links, and send reminders on their own, for $59 per month per employee or $149 for all three.
