Low-voltage licensing
Colorado
Colorado has no state-level low-voltage license; municipalities handle licensing. Denver, Aurora, Colorado Springs, and Boulder each have their own contractor registration requirements. The Colorado State Electrical Board does license MASTER and JOURNEYMAN electricians as individuals, but the contractor license itself is municipal.

Common pitfalls
Mistakes we see installers make when navigating Colorado licensing.
- Individual electrician licensing is state-level; contractor business licensing is municipal. Both are typically required.
- Denver requires registration as an Electrical Contractor through Community Planning and Development; Boulder has a separate process.
- Low-voltage-specific work under 50 volts often falls outside the State Electrical Board's jurisdiction but may still be covered by municipal contractor registration.
