STATE LICENSE
NoneSee what applies
There is no Title 12 article for general contractors in Colorado and no statewide contractor board. Nothing in state law tells a general contractor to hold a license, carry a bond, or prove a net worth. The entire regulatory system is municipal: a city or county adopts a building code, decides which contractor classes it will license, writes its own scope-of-work definitions, and refuses to issue permits to anyone who is not licensed in that class.
That makes the class you hold jurisdiction-specific in a way most states never see. Denver grades on building height and asks for notarized superintendent experience — seven years including ground-up high-rise for Class A. Pikes Peak Regional Building Department grades on occupancy group and square footage across B-A, B-B, B-C, B-D, B-E and B-F. Aurora splits the market into Commercial and Residential Building Contractor on ICC certification. Fort Collins runs Classes A through MM. The one statewide thread is energy code: under HB22-1362, any municipality or county that updates a building code must adopt an energy code at least as good as the 2021 IECC plus the state model electric and solar ready code, and after July 1, 2026 at least as good as the model low energy and carbon code.
The state sets the license floor; the county or city permit office controls filing, inspections, and local rules wherever the job site sits.
For general contracting in Colorado the local layer is not an overlay — it is the whole system. Denver runs a two-step process where an individual earns a supervisor certificate ($60, three years) and the company then holds a General Class A, Building Class B, Residential Class C or Specialty Class D license ($250, three years). Pikes Peak Regional Building Department, serving nine jurisdictions from one office, licenses Building Contractor A-1 through F on occupancy and square-footage scopes with $1,000,000/$2,000,000 general liability. Aurora licenses Commercial Building Contractor on ICC General Building A or B certification ($131 + $392) and Residential Building Contractor on ICC C ($131 + $235), and separately licenses Limited Building Commercial, Remodeling and Demolition contractors on registration plus three years of documented experience. Fort Collins licenses ten general contractor classes plus a long specialized-trade list. Because no state statute preempts them, all of these jurisdictions may both require the license and charge for it — the fee protections that shield electricians do not exist here. The one genuinely statewide constraint is HB22-1362: any municipality or county that updates a building code must move its energy code to 2021 IECC-equivalent performance plus the model electric and solar ready code, and from July 1, 2026 to the model low energy and carbon code.
The local offices section below names the exact permit desk for every Colorado county on file.
Each row names the issuing authority, cost, timeline, citation, and status behind the requirement — verified against the official source.
Published fees from the issuing authorities, as of September 2026. Local permit fees vary by project and jurisdiction — the basis is stated where a flat number does not exist.
A Denver Class B supervisor certificate is worthless in Colorado Springs and vice versa. Each jurisdiction writes its own scopes, so the same company is often Class B in one city and B-1 in another.
Denver requires notarized letters signed by the owner or controlling officer of the company worked for, or by customers, listing full project addresses, trades supervised, heights and exact construction start and end dates, limited to the last fifteen years.

Statutory consequences with their citations — not estimates, not “commonly cited” guesses.
There is no Colorado general contractor license and therefore no state unlicensed-practice offense. Operating without the required municipal license is an ordinance violation and, practically, means no permit issues and no inspections are scheduled.
An employer who fails to insure, lets coverage lapse or fails to renew shall not continue business operations while the default continues, and the director may order it to cease and desist and fine it for every day of default.
A lapse, cancellation or reduction of required coverage is cause for automatic suspension; more than six months lapsed and the contractor must reapply and retest.
Inside city limits, the city office listed here issues the permit; the county office serves unincorporated areas. Every office links to its official page.
