ELECTRICAL x COLORADO

Electrical contractor requirements in Colorado.

Electrical work is one of only three construction trades Colorado regulates statewide. The State Electrical Board, inside DORA's Division of Professions and Occupations, licenses three grades of individual electrician, registers every apprentice, and registers the contracting company itself — which must be, or employ full-time, a master electrician who may be the responsible party for one company only.

The unusual part is the preemption. C.R.S. 12-115-116(12) declares electrical licensing a matter of statewide concern and bars any city, town, county or city and county from examining, certifying, licensing or registering electricians licensed by the board. A local government may impose reasonable registration on an electrical contractor, but the statute says no fee shall be charged for it — which is why Denver lists its electrical contractor license at $0. Section 12-115-121(2) then caps a local electrical inspection fee at $120, CPI-adjusted annually since January 1, 2021, plus an optional tiered charge of eight percent, and forbids any other electrical permit or inspection charge.

LICENSE TRUTH
Colorado licenses electricians at the state level and forbids cities from testing or licensing them: the State Electrical Board issues Residential Wireman, Journeyman and Master licenses, registers apprentices and electrical contractors, and caps what a local electrical inspection may cost.
STATE ↔ LOCAL
Colorado gives electricians the strongest preemption of any construction trade. Cities cannot examine or license them, and cannot charge for the contractor registration they are allowed to require (C.R.S. 12-115-116(12)) — which is why Denver's contractor fee table prints $0 next to the electrical license and Pikes Peak Regional Building Department simply says no license other than a Colorado electrical contractor's license is required, with registration in the jurisdiction. What stays local is the permit and the inspection: a town, city, county or city and county with a building department that meets the board's minimum standards issues the permit and inspects, and everywhere else a state electrical inspector does it (C.R.S. 12-115-120). Even then the money is capped at $120 CPI-adjusted plus an eight percent tiered charge, and a utility may not energize the installation without proof of final approval.

NOTE
The city cannot charge you to be an electrician

Under C.R.S. 12-115-116(12) a local government may impose reasonable registration on an electrical contractor, but no fee shall be charged for that registration. Denver's own fee table lists the electrical license at $0.

NOTE
One inspection fee, capped

C.R.S. 12-115-121(2)(a) caps a local electrical inspection fee at $120 as adjusted annually by the Denver-Aurora-Lakewood CPI, allows an added tiered charge of eight percent based on size or valuation, and bars any other electrical permit or inspection charge.

NOTE
Start work before the permit and it doubles

If the application is not filed in advance of the commencement of an installation, the inspection fee is twice the board-set amount (C.R.S. 12-115-121(3)).

§ 08 · Colorado FAQ

Questions electrical contractors ask about Colorado.

Q01Do electricians need a state license in Colorado?+
Yes. No one may work at the trade of residential wireman, journeyman or master electrician without a license from the Division, and electrical contracting additionally requires a company registration held by or employing a master electrician (C.R.S. 12-115-109).
Q02Can a Colorado city make me take its own electrician exam?+
No. C.R.S. 12-115-116(12) declares electrical licensing a matter of statewide concern and bars any city, town, county or city and county from examining, certifying, licensing or registering state-licensed electricians. A city may require reasonable contractor registration, but it cannot charge a fee for it.
Q03How much can a city charge for an electrical inspection?+
No more than $120, adjusted annually by the Denver-Aurora-Lakewood consumer price index since January 1, 2021, plus an optional tiered charge of eight percent based on size or valuation. No other electrical permit or inspection charge is allowed (C.R.S. 12-115-121(2)(a)).
Q04When do Colorado electrician licenses renew?+
September 30 on a three-year cycle, with 24 hours of continuing education required per cycle. Electricians who got their first license by examination during the current period do not owe CE until after their first renewal.
