Homeowner’s Exams

Exams are offered in person at the Contractor Licensing counter. An appointment is not required to take a homeowner's exam. Exams are free.

Exams offered:

  • Electrical
  • Plumbing
  • Mechanical
  • HVAC (heating, ventilation, or air conditioning)

A state license may substitute for electrical or plumbing exams. No exam is needed for general construction, roofing, or siding.

Taking the Exam

To take the exam, you must be the legal owner and resident of the property. Please bring:

  • A photo I.D. matching the Assessor’s database, or
  • The deed listing you as an owner of the property. 

No other forms of ownership will be accepted. Copies of your deed may be available from the Denver Clerk and Recorder for a small fee.

Test Rules

  • The exam is currently only available in English.
  • Taking or using notes is prohibited.
  • Code books are provided for your use on a first-come, first-serve basis. You may bring your own code books or instructional books; however, they may be rejected if they contain notes or other inappropriate material.
  • Any contact with individuals outside of the test area is prohibited during the exam, including cell phones, radios, and pagers.
  • If you need to leave the test area for any reason, you must return all test materials immediately.

Anyone who fails an exam may retake it after waiting 30 minutes.

Using a "Designated Worker"

Homeowners may use the assistance of a designated worker to help complete the work and to take the exam. The designated worker cannot accept payment for services rendered and must be identified on the permit. To assist with the test, the designated worker must bring a current Colorado photo I.D. or driver’s license. A temporary Colorado driver’s license, other form of state-issued photo I.D., passport, or Green Card may also be accepted.
