Overall management and general oversight of a construction project in Fort Collins is the role of the "License Holder". The license holder, in turn, must provide direct on-site supervision on a regular basis through a qualified person designated as a "Construction Supervisor". The license holder may also be designated as the construction supervisor, as long as that person performs direct on-site construction supervision as noted herein, and meets the qualifications, including passing the required written exam.

A construction supervisor must be working exclusively for the license holder for the express purpose of providing direct, personal and ongoing on-site construction supervision. Such person must also be one or more of the following:

• A person with substantial ownership in the company;
• A company officer; or
• A company employee expressly hired to supervise construction projects.

Only those persons who possess a current supervisor certificate qualify as a construction supervisor in Fort Collins. A supervisor certificate can only be obtained by passing a written examination administered by the ICC and by meeting the specific experience requirements detailed further in this site. At least one supervisor must be designated and approved for each license obtained.

No permits will be issued to a contractor who does not possess a current license sufficient in scope for the proposed project, or at any time that a license holder does not have an approved construction supervisor designated.

No unlicensed person may act as a general contractor or as a specialized trade contractor, or personally perform construction work or a specialized trade unless they are:

• A homeowner performing construction on his/her own personal residence;
• A volunteer under the continuous supervision of an approved construction supervisor or homeowner;
• An employee of a current license holder (must be on payroll and meet the City, State and Federal test for an employee); or
• An exempt specialized trade subcontractor that has been registered with the City as defined in this packet.

"Use" of another person's license, or work performed under a building owner's permit by an unlicensed person, except as provided for above, is prohibited and may result in civil action or other disciplinary action against the parties involved.

The following are exemptions to the Fort Collins contractor licensing regulations:

1. A building owner and any unpaid volunteers or paid workers employed by said owner who perform only minor alterations and repairs to such building, provided that all such work is under the continuous personal supervision of said owner. For the purposes of this Section, minor alterations and repairs shall not include:
   • Significant structural alterations (except for the repair and replacement of existing window and door headers provided that such repair or replacement does not create larger openings or greater spans for such headers);
   • Alterations to fire-resistive assemblies as defined in the building code;
   • Alterations to or the installation of electrical, plumbing or mechanical systems, except for fixture replacement and emergency repairs, and except as otherwise permitted in this Article;

In the event such dwelling is destroyed or damaged, reconstruction thereof shall be exempt from the foregoing time period. Prior to performing any such construction, the owner must demonstrate sufficient knowledge and proficiency required to perform said construction as determined by the Building Official.
3. An owner or any unpaid volunteer under the continuous personal supervision of the owner of such building who personally demolishes any detached building housing an R-3 occupancy, as defined in the building code, or any building no larger than one thousand (1,000) square feet.
4. An employee of a contractor who is not otherwise regulated under this Article.
5. A partner, owner, or other company official of a licensed contractor who performs on-site construction under the direction of a qualified supervisor.
6. An exempt specialized trade subcontractor as defined in this Article.

However, any person who is paid for arranging for or supervising the overall construction or alteration to a building, including work involving any of the City licensed specialized trades or plumbing or electrical trades regulated by the City building codes is, by definition, a general contractor and must have an appropriate license. General contracting for basement and other interior finish work requires at least a Class D2 or Class E license.
8. Any person who is, without pay or compensation of any kind, performing construction or a specialized trade regulated under this Article and who is supervised directly by a licensed contractor and supervisor as specified in this Article to ensure that such work conforms to the applicable code(s).

Subcontractors and/or independent contractors are required to have their own license with the exception of exempt specialized trade subcontractors (see below).

• Is not a payroll employee of a specialized trade contractor; and

When such exempt subcontractors are used, the licensed specialized trade contractor is responsible for employing a City approved supervisor who is required to be readily available and present full-time on the project site where such subcontracted work is being performed to ensure that when completed such work fully conforms to applicable code(s).

Each exempt specialized trade subcontractor must be registered with the Building Services Department. See Exempt Specialized Trade Subcontractor registration packet.

All exempt specialized trade subcontractors must provide proof of general liability insurance coverage and, if utilizing payroll employees, proof of worker's compensation insurance coverage for all employees.
