The City of Thornton requires licensing for all contractors involved in the construction, alteration, remodeling, repairing and equipping of buildings and structures; installation of underground utilities; construction of roads and streets and construction of all City-owned water, sewer, and storm drainage facilities. Homeowners doing work on their personal private residence are not considered contractors and are not required to obtain a contractor license.
Applicants for Class A General, Class B Building, Class C Residential, Class D Mechanical and Class D Roofing License are required to provide proof that they are qualified to perform the work under that License Class. The City currently accepts a current valid contractor license from a reciprocating jurisdiction or a Contractor License Certification from the International Code Council for the currently adopted code. (For more information on ICC Contractor Certification go to www.iccsafe.org.) For the requirements of each License and for a list of jurisdictions that we reciprocate with, please refer to the Contractor License Information Packet.
The City of Thornton does not require proof of insurance to obtain a license. Please do not send us your insurance information.
