Who needs a license? - All residential building contractors and residential remodelers who contract with an owner to construct or improve dwellings for habitation by one to four families (including detached garages) and perform two or more special skills must be licensed unless exempt under one of the provisions noted below. The licensing requirement also applies to any person acting as a "spec" homebuilder. The only difference between a residential building contractor and residential remodeler is a residential building contractor can build new homes and work on existing structures, whereas a remodeler can only work on existing structures.

The following are exempt from the contractor/remodeler licensing requirements:

  • employees of a licensed contractor or remodeler;
  • material suppliers who do not install or attach the items;
  • owners doing work on their own property (unless they are engaged in building on speculation);
  • architects or engineers doing work within the scope of their practice;
  • people whose annual gross receipts from their residential contracting or remodeling activities are less than $15,000 (gross receipts are defined as the total amount derived from residential contracting or remodeling activities, regardless of where the activities are performed, and must not be reduced by cost of goods sold, expenses, losses or any other amount)*;
  • school districts and technical colleges;
  • specialty contractors who provide only one "special skill" (except residential roofers);
  • any person who only engages in activities found within one of the eight categories listed below is not required to be licensed (except residential roofers).

"Special skill" means one of the following eight categories

1. Excavation

  • excavation
  • trenching
  • grading
  • site grading

2. Masonry/concrete

  • drain systems
  • poured walls
  • slabs and poured-in-place footings
  • masonry walls
  • masonry fireplaces
  • masonry veneer
  • water resistance and waterproofing

3. Carpentry

  • rough carpentry
  • finish carpentry
  • doors, windows and skylights
  • porches and decks (excluding concrete footings)
  • wood foundations
  • drywall installation (excluding taping and finishing)

4. Interior finishing

  • floor covering
  • wood floors
  • cabinet and countertop installation
  • insulation and vapor barriers
  • interior or exterior painting
  • ceramic, marble and quarry tile
  • wallpapering
  • ornamental guardrail and installation of prefabricated stairs

5. Exterior finishing

  • siding
  • soffit, fascia and trim
  • exterior plaster and stucco
  • painting
  • rain carrying systems, including gutters and down spouts

6. Drywall and plaster

  • installation
  • taping
  • finishing
  • interior plaster
  • painting
  • wallpapering

7. Roofing

  • roof coverings
  • roof sheathing
  • roof weatherproofing and insulation
  • repair of roof support system, but not construction of new roof support system

Roofers are required to obtain a license.

8. General installation specialties

  • garage doors and openers
  • pools, spas and hot tubs
  • fireplaces and wood stoves
  • asphalt paving and seal coating
  • exterior plaster and stucco
  • ornamental guardrail and prefabricated stairs

Roofers: For more information regarding the specific licensing requirements for people who only engage in residential roofing activities.
Siding contractors: Siding contractors who also install doors, windows or skylights must be licensed as a residential building contractor or remodeler.

Anyone who is licensed as a residential building contractor or remodeler can engage in all of the special skill categories noted above, including roofing, without obtaining a separate roofer license

Building contractor and remodeler license - The licensing program requires only companies to obtain a license (therefore, in the case of an individual, the license is issued to an "individual proprietorship"). However, each company must designate one individual who will serve as a "qualifying person" regardless of whether the licensee is an individual proprietorship, partnership or corporation. The qualifying person is the individual who must take the required examination and fulfill the continuing education requirements for the licensee.

Licensing requirements for a building contractor license: - Attach a copy of the Certificate of Assumed Name, filed and stamped by the Minnesota State, if the business name is different than the legal name of the individual, corporation or other business entity.

For example:

An individual proprietor who intends to do business using a company name that does not include the individual's first and last name;

A partnership that intends to do business using a name that does not include the first and last name of each individual partner; or

A corporation or other business entity that intends to do business under a name that is not the legal corporate name or business entity name.

Examples: "John Smith Construction" would not be required to attach a Certificate of Assumed Name if John Smith is the sole owner of the business. However, "Smith's Construction" would be required to attach the certificate, because it does not contain the full first and last name of the owner. Similarly, if a legally incorporated company, such as "ABC Construction, Inc.," intends to do business as Acme Construction, the company must attach a Certificate of Assumed Name to the license application. The Certificate of Assumed Name is required to provide information to the public about the true identity of the business owner.

Examination results expire after two years. If the examination was taken more than two years prior to this application, attach Course Completion Certificate(s) documenting seven hours of continuing education for each license period after the expiration of the examination results. The qualifying person must be chief executive officer of the corporation, general partner of the partnership, chief manager of the LLC or a managing employee who is regularly employed by the applicant and is actively engaged in the business of residential contracting or residential remodeling on behalf of the applicant.
