Our office issues licenses and certificates, to both individuals and companies who perform work within Denver that requires a building permit or right-of-way permit. Before applying for a contractor license, an applicant must hold a trade-specific supervisor certificate or employ a supervisor certificate holder. License applications will not be accepted until supervisor certificates have been approved. Denver does not accept or reciprocate contractor licenses and/or certificates from other counties or states.
Permits will only be issued to a contractor licensed for that work in Denver. The person picking up the permit can demonstrate the validity of the contractor’s license on the permit application by bringing an original contractor license card (no copies or faxes accepted), or a check or credit card from the licensed company. NOTE: The business name on the check or credit card must match the exact company name and spelling as listed on the license card in our records.
Once you demonstrate proficiency in a specific area by passing a Home owner's exam you will be able to complete several types of projects yourself—without hiring a contractor.
Homeowner’s Exams are given Monday through Friday, 8:00 am to 3:00 pm at Contractor Licensing, 201 W Colfax, 2nd Floor, Denver, CO 80202. There are no fees for the exam. For Homeowner verification you must be listed on the Assessor’s website at http://www.denvergov.org/Property as the property owner or provide us 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.
The Owner-Occupier 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 at http://www.denverbbb.org. 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.
