Contractor Registration


The County’s Contractor Registration Program requires contractors applying for permits to be registered. All State issued electrical and plumbing contractors and company masters licensing are verified through the Department of Regulatory Agencies (DORA) prior to the issuance of a permit. If there is a contractor change during construction, Douglas County shall be notified, and the permit will be moved into a “Suspended” status until a new contractor is selected and registered.  Douglas County inspectors will conduct random on-site inspections to verify current licenses and appropriate licensed installer-to-apprentice ratios. Inspectors may report any violations to the State Board.

Contractor registration fees are currently waived in Unincorporated Douglas County.

The Douglas County Board of County Commissioners has determined that waiving the collection of contractor registration fees is in the best interest of both the business sector and the citizens of unincorporated Douglas County. Therefore, effective July 1, 2013 the registration fees for Contractors of all types and classes, as set forth in Sections 116.3 and R116.3 of Resolution No. R-009-061, are hereby waived and shall not be collected by the Chief Building Official until further resolution of the Board of County Commissioners.

The waiver only pertains to fees, all remaining requirements for Contractor’s registration as set forth in Douglas County Resolution R-009-061. The 2018 International Building Code, 2018 International Residential Code, 2018 International Plumbing Code, 2018 International Mechanical Code, 2018 International Fuel Gas Code, 2018 International Energy Conservation Code, and the 2017 National Electrical Code, shall remain in full force and effect Resolution R-019-124.

General contractors, roofing and mechanical contractors must be registered with Douglas County. Electrical and Plumbing contractors must be registered with Douglas County by providing proof of Licensing with the State of Colorado.

Contractors are required to submit proof of Workers Compensation Insurance (if applicable) and Business Liability Insurance. Douglas County’s Contractor registration process is not intended to be a “Preferred Contractor List”. Douglas County will not recommend contractors, and a contractor license or registration does not guaranty the quality of work beyond meeting minimum insurance requirements.
