Louisiana Contractor Licenses

The State of Louisiana has Licensing Boards and Departments that regulate the work of individuals and businesses performing in the construction industry. The main regulatory entities issuing the licensing are Louisiana State Licensing Board for Contractors (LSLBC), State Plumbing Board of Louisiana (SPBL), Louisiana State Board of Home Inspectors (LSBHI), Louisiana Department of Public Safety (DPS), Louisiana Department of Environmental Quality (LDEQ)and Louisiana Agriculture & Forestry (LDAF).

As part of the application process, candidates must take and pass the corresponding tests and present documentation to support their application. In most cases, the board administers the examinations for the licenses or certifications within that board. The International Code Council (ICC)is responsible for administering the test for the Louisiana State Uniform Construction Code Council (LSUCCC)certifications. The Louisiana State Licensing Board for Contractors provides a “Business and Law” interactive educational course that is required for ALL licenses except for the Home Improvement Registration.

Below is a list of all the existing trades for Louisiana. Each contains the requirements, exams, books, and all the information related to the application process.

Board for Contractors (LSLBC)

The Louisiana State Licensing Board (LSLBC) is the entity in charge of issuing contractor licenses in the state. It also ensures legal standards and qualified work performance from contractors working in the construction industry.

To obtain a contractor license, each candidate must apply through the LSLBC Online License Application, meet the requirements, and present a trade examination if required. The LSLBC has reciprocal agreements with other states. Each board offers different license arrangements depending on the classification trade.

The Lead Based Paint Abatement and Removal (7-417) license is considered a contractor license that can be found listed within the LSLBC. However, the application form, exam, and licensing process are administered by the Louisiana Department of Environmental Quality (LDEQ).

Louisiana Classification List

The Louisiana State Licensing Board has an official classification list where the applicant can review all the trades for which the state of Louisiana offers contractor licenses and the different classifications used to categorize the trades.

• The Major Classification refers to the main category that allows the contractor to bid and perform work in, for example, Building Construction, Electrical, Heavy Construction, or Residential Construction Building and any subclassifications listed under the Major Classification. (some exceptions may apply)
• Subclassifications are trades listed under a Major Classification. These classifications are for contractors looking to be licensed in a specific trade. Examples of subclassifications are Drywall (7-10) or Painting and Flooring (7-49). Those two trades are under the Major Classification Building Construction (1)
• The Specialty Classification category does not fall under any Major Classification within the Louisiana Contractor Licensing Board. Coverings and Linings, Water Well Drilling, or Leaks Repairs are examples of Specialty Classifications
• Credential is a classification required for applicants that must be certified or licensed by an outside agency or organization and/or other documents

Agriculture & Forestry (LDAF)

The Louisiana Department of Agriculture and Forestry (LDAF) administers programs that regulate the environmental impact of commercial businesses, from a farm to an industrial-level economy, through State Legislation.

Inside LDAF is the Louisiana Horticulture Commission (LHC), which regulates workers at horticultural businesses, preventing fraudulent practices and encouraging continuing education, achieving high-quality services by green industry professionals while meeting the Louisiana Laws listed in the LA State Legislature. The LDAF provides an official Agriculture & Forestry reference list for licensing certification. Therefore, the applicants must complete all the respective forms to apply for the test.

The Arborist, Landscape Horticulturist, and Landscape Irrigation Contractor Licenses are listed under the LDAF; however, the licensing process is done through the LA Horticulture Commission. If the applicant wants a reciprocal certification for pesticide, the pesticide waiver form must be completed and sent to the Department of Agriculture & Forestry.

Yard Work does not require a license because it is not regulated. This includes: cutting lawns, edging, and hand-weeding beds.
