Exam Requirements

An exam is required in order to obtain a Supervisor Certificate for all General Contractor licensing categories and many of the Specialized Trade contractor licensing categories.

The 2009 IBC (International Building Code) with City Amendments became effective October 11, 2010 for commercial and multi-family construction. The 2009 IRC (International Residential Code) with City Amendments also became effective October 11, 2010 for single family, duplex and property line townhomes. As as result of these new code adoptions, we will no longer provide any City of Fort Collins supervisor certificate exams for General Contractors. The only new supervisor certificate exam offered by the City of Fort Collins will be for the Specialized Trade of Framing. An applicant for any of the license/certificates noted below(except Framing) must provide documentation of a passed ICC (International Code Council) administered exam from an approved Pearsonvue testing center, unless an exam is not required to obtain a supervisor certificate for that class of license. Please see the bottom of this page for a listing of those licenses not required to test. A list of approved ICC testing centers is available from the ICC website: www.iccsafe.org See specific license categories below for more details on other exam requirements.

A short "refresher" exam covering the adopted City Amendments to the 2009 IBC and/or the 2009 IBC will be required for all new General Contractors and any City licensed General Contractors that do not renew their supervisor certificate within 60 days of the expiration date of their certificate. The Amendment exams are open-book, with a 2 hour allowance to complete the exam. City Amendments may be downloaded from the Building Services web page . The Amendment exam code version (IBC or IRC) will be determined by the license category, e.g., commercial/multi-family would take the IBC version, residential would take the IRC version. There is a $35 testing fee for any City Amendment exam that must be paid prior to taking the exam. The minimum passing score is 75%.

Amendment exams and the Specialized Trade Framing exam will be offered by the City of Fort Collins on the 1st and 3rd Thursdays of every month, at 9:00 a.m. at the Community Development and Neighborhood Services building, located at 281 N. College Avenue. Check in time is at 8:30 a.m. If you are unable to attend a regular testing date/time, special arrangements may be made for testing on a different day/time, please call 970-416-2740 to schedule.

An applicant is limited to two (2) attempts on the same exam within any six month period unless the applicant can demonstrate, to the satisfaction of the Building Official, that they have completed additional coursework covering the building code, or other applicable codes, or unless they receive approval from the Building Review Board. It is requested that you pre-register for the test as seating may be limited. City of Fort Collins exam formats are a mix of multiple-choice, fill-in-the-blank, and true/false responses. Questions are not intended to be trick questions. All have only one correct response and should be read carefully and completely since there are many exceptions and conditions in the Code. Only basic mathematics is required and a simple calculator is useful.
