Novel Coronavirus (COVID-19) Update
To protect the health and well-being of our community and to support social distancing guidelines, the contractor licensing counter is temporarily closed. Contractors should use the online options below to apply for and renew their licenses.
Our office issues licenses and certificates to individuals and companies who perform work within Denver that requires a building permit or right-of-way permit. Denver does not accept or reciprocate contractor licenses and/or certificates from other counties or states.
Contractors will need to show their license to pick up building permits. Permits are only issued to a contractor licensed to perform work in Denver. The person picking up the permit must verify the contractor’s license on the permit application by bringing (1) an original contractor license card (no copies or faxes accepted), or (2) a one-day license card signed by an owner or officer on file.
Review the prerequisites required for supervisor certificates, contractor licenses, and right-of-way licenses and print out all documents. Before applying for a contractor's license, the applicant must hold a trade-specific supervisor certificate, employ a supervisor certificate holder, or hold a state electrical or plumbing license. Contractor license applications are not accepted until supervisor certificates have been approved.
Both licenses and certificates expire every three years. You can renew online within 30 days of expiration. You can also renew by mail or in person.
Review the prerequisites required and the steps to apply for supervisor certificates. Certificates are issued to individuals who can show hands-on experience in the field for which they are applying.
Review and submit the following:
Remember, contractor licensing in Denver is a two-step process: a license applicant must hold a supervisor certificate (or a state electrical or plumbing license), or employ someone who holds a supervisor certificate before applying for a contractor license.
You can find license and certificate renewal forms below. If a license has been expired for over a year, it will require reinstatement.
Note: We do not mail renewal notices.
Once you demonstrate proficiency in a specific area by passing a homeowner's exam you will be able to complete several types of projects yourself—without hiring a contractor.
These exams are given Monday through Friday, 8:00 am to 3:00 pm at Contractor Licensing, 201 W. Colfax Ave., 2nd Floor, Denver, CO 80202. There are no fees for the exam, but you must be listed on the Assessor’s website as the property owner or submit a 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 Clerk and Recorder for a small fee.
A state license may substitute for electrical or plumbing exams. No exam is needed for general construction or roofing/siding.
The owner listed on the Assessor's website must be the individual taking the exam.
Contractors are licensed to ensure that they are competent and capable of meeting the relevant technical and safety standards for your project. Each license type has a defined set of competence criteria that contractors must meet to achieve and maintain a license.
Before any demolition or the first nail is hammered, a good home remodeling contractor has already done a lot of work for you. Denver, like most cities and communities has specific building codes that must be followed. In order to have any additions to or remodeling of your home, you need the correct permits.
Not only are reputable home contractors experienced at a wide range of home remodeling techniques, they also have contacts with other home improvement professionals you might need like plumbers and electricians.
Each contractor should have insurance and warranty information available to you. Typically contractors provide a one year warranty on material and labor, check with the contractors to verify the extent of any warranty extended to you.
Be sure to talk to and visit at least three previous clients and utilize the Better Business Bureau. You should also insist on proof that the contractor is insured and bonded. Check with the insurance company that the contractor's policy is current.
After selecting a contractor, get a written contract detailing the work to be performed, the costs associated with each task and a timeframe with estimated start and finish dates. Sign a contract that protects against liens from subcontractors and consider these additional tips for the completion of a good contract:
*Warning: Beware of unscrupulous contractors that suggest you, as the homeowner, secure the permit in your name. The permit holder is legally responsible for the completion of the job to code standards.
