Colorado Low Voltage Contractor License Requirements (2026)

Colorado does not issue a dedicated state low-voltage contractor license. The DORA State Electrical Board licenses electricians and electrical contractors under C.R.S. §12-115, and structured cabling under 50 V is generally exempt from state electrical licensing under §12-115-120(3). Burglar and fire alarm work falls under the same exemption — Colorado has no statewide alarm contractor license. However, most Colorado municipalities (Denver, Aurora, Colorado Springs, Boulder, Fort Collins) require local low-voltage / alarm contractor registration through the building department, and fire alarm acceptance is enforced locally under NFPA 72. Some jurisdictions require NICET Fire Alarm Systems Level II for commercial fire alarm projects.

Governing Authority

Colorado Department of Regulatory Agencies — State Electrical Board (DORA) administers and enforces this credential under the authority of Colorado Revised Statutes Title 12 Article 115 (Electricians); 3 CCR 710-1. The DORA State Electrical Board licenses Residential Wiremen, Journeyman Electricians, Master Electricians, and Electrical Contractors statewide, adopts the National Electrical Code by reference, and conducts disciplinary proceedings.

Eligibility Requirements

At a minimum the applicant has to be 18 years old and supply a valid Social Security Number. No Colorado residency requirement.

Good moral character

DORA reviews criminal history on the electrical contractor application. Local jurisdictions impose their own background requirements for low-voltage / alarm registrations.

Background investigation

DORA does not require fingerprinting for low-voltage scope. Some Colorado municipalities require local police background checks for alarm installer registrations.

Experience & Education Matrix

No fixed number of years of experience is set out in the cited sources for this credential; instead, the controlling requirement is No state experience requirement for low-voltage work because the scope is exempt from state licensing under §12-115-120(3). Local jurisdictions typically require one to two years of supervised experience under a registered low-voltage installer. Fire alarm planning superintendents need NICET Fire Alarm Systems Level III on most commercial projects..

Accepted proof of experience or eligibility

Local jurisdiction Experience Verification Form (varies by city)
BICSI Installer or NICET Fire Alarm Systems certificates
W-2 statements covering the qualifying period
Manufacturer training certificates

Education substitution

BICSI and NICET certifications are widely recognized by Colorado AHJs as substitutes for portions of any local experience requirement.

Examination Structure

Examinations are administered by No state exam for low-voltage scope. Some Colorado municipalities use ICC, BICSI, or NICET certification as the qualifying credential. Denver Building Code Division requires the ICC Electrical Inspector exam for fire alarm AHJ acceptance.. The applicant must pass the following examination parts before the license can issue:

BICSI Installer 1 (or higher) — for structured cabling — 100 questions, 180 minutes, passing score 70%
NICET Fire Alarm Systems Level II — for fire alarm work — 100 questions, 180 minutes, passing score 70%

Examination fee: BICSI Installer 1 exam $185; NICET Fire Alarm Systems Level II exam $315.

Retake policy: BICSI and NICET allow re-tests after a 30-day waiting period.

Insurance & Financial Security

The cited materials impose no contractor license bond for this credential. Bear in mind that specific contracts, permits, or public works can still require their own bonds.

General liability

DORA does not require liability insurance for exempt low-voltage work. Most Colorado municipalities require $300,000 – $1,000,000 commercial general liability for local low-voltage contractor registration.

Workers' compensation

Workers' compensation is mandatory under C.R.S. §8-44 for any Colorado employer with one or more employees.

Additional financial requirements

No financial statement required.

Application and License Fees

Fee	Amount
Application (non-refundable)	No separate state fee
Examination	$500
Initial license	No separate state fee
Renewal cycle varies by jurisdiction	No separate state fee

Maintenance & Renewal

The Colorado DORA State Electrical Board Residential / Journeyman Wireman Plus Local Low-Voltage Registrations does not have a single statewide renewal cycle; follow the issuing board or local jurisdiction schedule. The cited materials name no distinct statewide fee for renewal. No state renewal cycle for low-voltage scope; local jurisdictions vary from annual to triennial renewals.

Continuing education: BICSI and NICET certifications require continuing education hours every three years to maintain. Local jurisdictions impose their own renewal requirements.

Reciprocity and Endorsement

Colorado does not accept the NASCLA Accredited Examination for this classification.

Reciprocal State	Accepted Exam	Conditions
No formal bilateral reciprocity agreements identified.

No statewide low-voltage license means no reciprocity. NICET and BICSI certifications are portable across jurisdictions.

Step-by-Step Application Roadmap

Confirm scope is exempt from DORA. Pure low-voltage work under 50 V is exempt from state electrical licensing under C.R.S. §12-115-120(3). Tying into 120 V branch circuits requires a DORA-licensed electrician.
Identify local jurisdictions. Each Colorado municipality (Denver, Aurora, Boulder, Colorado Springs, Fort Collins) has its own low-voltage / alarm contractor registration. Check the building department for each.
Earn industry credentials. BICSI Installer 1 for cabling; NICET Fire Alarm Systems Level II for fire alarm; manufacturer credentials for access control / CCTV.
Register with each jurisdiction where you work. File local low-voltage contractor registration with the building department. Provide proof of insurance and credentials.
Pull electrical permits for fire alarm work. Most Colorado AHJs require an electrical permit and acceptance test for commercial fire alarm projects per NFPA 72.
Maintain workers comp and insurance. Renew workers comp and liability annually per C.R.S. §8-44.

Common Filing Mistakes

Based on the board's own instructions and the sources cited here, the problems below are what most often stall a Colorado Low Voltage application.

Assuming the state exempts everything

The state exemption applies to pure low-voltage work under 50 V. As soon as the installer ties into a 120 V branch circuit, a DORA electrician is required.

Skipping local jurisdiction registration

Each Colorado city has its own low-voltage / alarm registration. Operating without local registration is unlicensed contracting at the municipal level.

Missing NICET on commercial fire alarm projects

Most Colorado AHJs require NICET Fire Alarm Systems Level II for commercial fire alarm acceptance even though DORA does not.

Underestimating workers comp coverage

Colorado requires workers comp for any employer with one or more employees. Lapses trigger penalties.

Multiple jurisdictions multiply paperwork

A contractor working in five Colorado cities maintains five separate registrations and renewals. Plan administrative time accordingly.
