What is a Louisiana contractor license and who needs one?

A Louisiana contractor license is issued by the Louisiana State Licensing Board for Contractors (LSLBC) under Title 37, Chapter 24 of the Louisiana Revised Statutes (R.S. 37:2150 et seq.). Louisiana is a monetary-threshold state: whether you need a license, and which one, turns on the dollar value of the project. Per R.S. 37:2150.1, a Commercial license is required when a commercial project is valued at $50,000 or more, a Residential license is required for new residential construction valued at $50,000 or more, a Home Improvement Registration is required for repairs or improvements to an existing residential structure valued at $7,500 or more (and below $50,000), and a Mold Remediation license is required for mold work valued at $7,500 or more. Every applicant designates a qualifying party for each classification and for the Louisiana Business and Law requirement, submits a financial statement showing the required net worth ($50,000 for commercial and residential, $25,000 for home improvement and mold), and passes the Business and Law course plus any trade exam tied to the classification. Statutory fees are capped at a $100 license fee, a $50 examination fee, a $50 home improvement fee, a $100 renewal fee, and a $50 delinquent fee. The initial license is valid for one year, then renews on its anniversary for a 1, 2, or 3 year term, and residential licensees complete 6 hours of continuing education each year.

Every fact below traces to the LSLBC published pages or the Louisiana Contractors Licensing Law (R.S. 37:2150 et seq.) in the board’s official Blue Book. Verify any figure against the source before you pay a fee, because the board can adjust fees and classification rules.

Do you need a contractor license in Louisiana?

Louisiana does not license every job. It licenses by project value, and the threshold is the first thing to settle. Per R.S. 37:2150.1, the project value includes the entire cost of labor, materials, rentals, and all direct and indirect expenses, counted regardless of who pays for them or whether materials are donated. You cannot split a job into phases to slip under a threshold, because the principal contract is the agreement to perform the entire scope of work.

The four monetary thresholds

Residential vs commercial vs home improvement

Commercial covers any construction project except residential structures intended primarily as a residence with no more than two dwelling units. Residential covers new construction of a residential structure. Home improvement covers the reconstruction, alteration, renovation, repair, modernization, conversion, improvement, removal, or demolition of, or an addition to, an existing residential structure. A home improvement contractor works between $7,500 and less than $50,000 and may not perform structural work integral to the structural integrity of the building. Once a residential job hits $50,000, it moves from the Home Improvement Registration into the Residential license.

Statutory exemptions (narrow)

The law carves out a small set of exemptions. A residential property owner who physically performs home improvement work on their own personal residence does not need a registration. An owner or tenant, or a managing agent or employee of an owner or tenant, who performs mold remediation on their own property is exempt from mold licensure. Work below the dollar threshold for each category falls outside the licensing requirement, although the prohibition on splitting a project to dodge a threshold still applies.

License types and classifications

Per R.S. 37:2156.1, an applicant selects classifications from the list of major classifications or from the subclassifications and specialty classifications adopted by board rule. The board states the classification on the license, and a licensee may not bid or perform work outside the classification under which the license was issued.

The 11 major classifications

• Building construction
• Highway, street, and bridge construction
• Heavy construction
• Municipal and public works construction
• Electrical (license required at $10,000 or more)
• Mechanical (license required at $10,000 or more)
• Plumbing (license required at $10,000 or more)
• Hazardous materials (license required at $1 or more)
• Residential construction
• Mold remediation
• Home improvement

The four credentials most contractors choose

Subclassifications and specialties

Beyond the four headline credentials, the board maintains a long list of subclassifications and specialty classifications. Residential construction includes subclassifications such as Residential Roofing and Residential Swimming Pools, each with its own trade exam. Commercial specialty classifications cover scopes such as Carpentry, Concrete Construction, Curb, Gutter, and Driveways, Glass and Glazing, Insulation, Painting and Coating, Solar Energy Equipment, and Water Well Drilling. A Labor Only specialty exists for subcontractors who provide labor on commercial projects, and it carries a lower net worth bar and no trade exam. Review the board’s Examinations and Classifications list before applying so you select every scope you intend to perform.

Financial statement and net worth requirements

Per R.S. 37:2156.1(B), every applicant submits a financial statement on a board form, current to within twelve months of filing, prepared and signed by an accountant, bookkeeper, or certified public accountant and signed by the applicant. The required net worth depends on the credential:

• Commercial and residential licenses, their subclassifications, and most specialty classifications: net worth of $50,000 or more.
• Home improvement, mold remediation, and labor only specialties: net worth of $25,000 or more.

An applicant who falls short of the required net worth may satisfy the requirement by submitting an irrevocable letter of credit equal to the net worth requirement plus the amount of any negative net worth. The financial statement is confidential and is not subject to the Louisiana Public Records Law. This financial bar, rather than a years-of-experience rule, is the gate that surprises many first-time applicants, so prepare the statement early.

Business and Law plus trade exams

Per R.S. 37:2156.1(D), an applicant designates a qualifying party for each classification and for the Louisiana Business and Law requirement. The qualifying party must satisfy any examination and credential requirement. There are two layers to clear.

The Business and Law requirement

Every applicant must complete the Louisiana Business and Law course. An exam or administrative fee applies for the Business and Law requirement and for each classification. The Business and Law layer covers Louisiana licensing law, contracts, lien and bid rules, business organization, insurance, and the board’s rules. It is the one requirement that is shared across every credential type, from commercial to home improvement.

Trade exams by classification

Most classifications also require a trade exam specific to the scope of work. Residential subclassifications such as Residential Roofing and Residential Swimming Pools each carry their own trade exam. Some classifications accept a recognized credential in lieu of a trade exam, such as a plumbing certificate or an asbestos certificate. Two notable exceptions exist: the Home Improvement Registration requires no trade exam, and the Labor Only specialty requires no trade exam. The Mold Remediation credential is different again, requiring evidence of at least 24 hours of training in mold remediation and basic mold assessment before the license is issued.

How to apply for a Louisiana contractor license: the 8-step process

The board runs applications through its online portal at arlspublic.lslbc.louisiana.gov, and an application stays active for one year from submission. Map every step before you start so the financial statement, insurance, and exams line up.

1. Confirm your threshold and pick your credential

   Start with the dollar value of the work you intend to bid. Commercial and new residential construction at $50,000 or more need a license, home improvement on existing homes needs a registration at $7,500 and up, and mold remediation needs a license at $7,500 and up. Pick the credential and the classifications that match every scope you plan to perform, because the board limits you to the classifications stated on your license.

2. Designate your qualifying party

   Name a qualifying party for each classification and for the Louisiana Business and Law requirement. The qualifying party can be a principal or a full-time employee, must complete the application, pass the background investigation, and satisfy any exam or credential requirement. One qualifying party can cover a subsidiary of a licensee.

3. Prepare the financial statement

   Complete the board’s financial statement form, current to within twelve months, prepared and signed by an accountant, bookkeeper, or CPA and signed by you. Show net worth of $50,000 for commercial or residential, or $25,000 for home improvement or mold. If you fall short, prepare an irrevocable letter of credit to make up the difference.

4. Complete the Business and Law course

   Every applicant completes the Louisiana Business and Law course covering licensing law, contracts, liens, bids, and board rules. An exam or administrative fee applies. This shared requirement is the same whether you pursue a commercial, residential, home improvement, or mold credential.

5. Pass the trade exam for your classification

   Sit the trade exam tied to each classification that requires one, such as Residential Roofing or Residential Swimming Pools. Home Improvement and Labor Only require no trade exam. Mold Remediation instead requires 24 hours of mold training. If you hold a Building Construction license, you are exempt from the residential trade exam.

6. File your insurance certificates

   Residential, home improvement, and mold applicants submit workers’ compensation certificates and general liability coverage of at least $100,000 (or $50,000 for mold remediation). Commercial applicants are not required to file insurance with the board, though general liability remains a practical necessity on most commercial jobs.

7. Submit the application and pay the fees

   Submit the application through the LSLBC portal with the statutory fees: a $100 license fee, a $50 examination fee for the Business and Law requirement and each classification, and a $50 home improvement fee where it applies. Out-of-state contractors may owe an additional non-domiciliary surcharge of up to $400. Fees are nonrefundable.

8. Clear the background investigation and receive your license

   The applicant, each principal, and each qualifying party complete a background investigation covering fiduciary matters such as bankruptcies, judgments, and liens, plus any criminal conviction. The board may deny approval for cause. Once approved, the board issues the license with your classification stated on it, and you can bid and perform work within that scope.

Total cost of a Louisiana contractor license in 2026

Louisiana’s statutory fees are low and capped by R.S. 37:2156(C). The bigger line items are the financial statement preparation, exam prep, and the insurance that residential and home improvement applicants must carry. Most applicants complete the board side of the process for a few hundred dollars in fees, plus insurance and prep.

Statutory fees (capped by R.S. 37:2156)

Note the education trust fund fee: per R.S. 37:2156(K), the board adds a $100 per year fee on each renewal dedicated to accredited construction management programs, but the renewal form lets a contractor opt out of that dedication. The base statutory fees themselves are the $100 license fee, $50 examination fee, $100 renewal fee, $50 delinquent fee, and $50 home improvement fee.

Other initial and ongoing costs

Beyond board fees, budget for the financial statement preparation by an accountant or CPA, exam prep for the Business and Law and trade exams, general liability insurance (the board requires at least $100,000 of coverage for residential and home improvement, $50,000 for mold), workers’ compensation for residential, home improvement, and mold applicants, and continuing education (6 hours per year for residential licensees). General liability premiums for a small Louisiana residential contractor commonly run several hundred to a couple thousand dollars per year depending on revenue and trade, and workers’ compensation scales with payroll once you have employees.

How long it takes to get a Louisiana contractor license

Timeline depends mostly on how quickly you assemble the financial statement, complete the Business and Law course, and sit any trade exam. Applicants who line up the financial statement and insurance in parallel with exam prep often finish in 4 to 8 weeks. The application remains active for one year from submission, so there is room to complete outstanding requirements, but the board writes off the application and fees if the requirements are not met within that one-year window. The longest delays come from financial statements that need rework, insurance certificates that arrive late, or background investigation follow-ups.

Renewal and continuing education

Per R.S. 37:2156(H), a Louisiana license expires on the anniversary of the date it was originally issued. The initial license is valid for one year, and on renewal a licensee elects a 1, 2, or 3 year term, though licenses that depend on insurance or certifications are not eligible for multiple-year renewal. The renewal fee is capped at $100.

The 15-day grace window and the delinquent fee

After a license expires, the holder has 15 days to file the renewal without penalty. A renewal filed more than 15 days after expiration is charged a delinquent fee of up to $50. If a license is not renewed within one year of its expiration, it is no longer eligible for renewal, and the contractor must submit a new application for a new license.

Continuing education for residential licensees

Per the LSLBC continuing education rules, a residential building contractor must complete a minimum of 6 hours of continuing education annually through a board-approved provider. There are no continuing education requirements for commercial, mold, or home improvement contractors or registrants. Residential licensees retain their completion certificates for five years and produce them on request. Holding a current commercial license in a major classification such as Building Construction can satisfy the residential continuing education requirement.

Insurance and workers’ compensation

Per R.S. 37:2156.1(E), residential construction and its subclassifications, mold remediation, and home improvement applicants must submit certificates of workers’ compensation coverage in compliance with Title 23 of the Louisiana Revised Statutes and general liability insurance of at least $100,000 (or liability trust fund protection of at least $100,000). The checklist published by the board sets a lower general liability floor of $50,000 for mold remediation. Commercial applicants are not required to file insurance with the board.

That board filing rule is the floor, not the practical ceiling. On most jobs of any meaningful size, general contractors and project owners expect $1,000,000 per occurrence general liability before a contractor can pull a permit or work as a sub. Workers’ compensation is mandatory for residential, home improvement, and mold credentials at the board-filing stage, and Louisiana’s broader workers’ compensation law applies once you employ workers regardless of credential. Bind coverage before the first qualifying employee starts, because gaps create personal liability for any work-related injury.

Setting up your contracting business in Louisiana

Most Louisiana contractors run the business through an LLC or corporation that holds the license, with an individual named as the qualifying party. Entity formation and tax registration are prerequisites, not afterthoughts.

Entity choice and Secretary of State registration

The single-member LLC is the most common structure for a small Louisiana contractor because it gives liability protection without double taxation. Form the entity with the Louisiana Secretary of State before applying so the license issues in the correct legal name. A person licensed or registered by the board must bid, contract, and perform work in the exact name on the current license and the board’s official records, so the entity name and the license name have to match.

Federal EIN and Louisiana tax registration

Pull a free EIN from the IRS. Register with the Louisiana Department of Revenue for sales and use tax if your work involves the retail sale of materials, and register for unemployment and workers’ compensation once you hire. Residential, home improvement, and mold applicants must show workers’ compensation at the board-filing stage, so set up payroll and coverage before you file.

Penalties for unlicensed contracting in Louisiana

Per R.S. 37:2163, it is unlawful to engage in the business of contracting, or to act as a contractor as defined in the law, without an active license. A first violation is a misdemeanor punishable by a fine of up to $500 per day of violation, three months in prison, or both. If an unlicensed person violates the law and causes harm or damage to another in excess of $300, the penalty rises to a fine of $500 to $5,000, imprisonment with or without hard labor for six months to five years, or both. The district attorney where the violation occurs has sole authority to prosecute.

On top of the criminal exposure, R.S. 37:2164 gives the board a civil penalty of up to ten percent of the total contract or the value of the work bid or being performed, after notice and a hearing, plus administrative costs and attorney fees. The board can also issue a cease-and-desist order and seek an injunction. Beyond the fines, contracting without the required license puts collection at risk, so the practical cost of skipping the license is far higher than the license itself.

Local rules across Louisiana

The LSLBC license is the statewide qualification, but parishes and home-rule cities layer their own permit and registration requirements on top. Per R.S. 37:2160, local permit offices issue building permits and may not waive the state license requirement. No parish issues a separate general contractor license that replaces the state credential, but local building departments run their own permit, inspection, and sometimes registration tracks.

Plan local permits as part of the initial timeline, not as an afterthought. Plumbing, mechanical, and electrical contractors licensed by the board are, per R.S. 37:2156.1(H), excluded from local examination procedures and may bid and perform within any local jurisdiction after paying the appropriate fees, which simplifies multi-parish work for those trades.

Common pitfalls to avoid

Beyond the application itself, four pitfalls trip up Louisiana contractors:

• Misreading the threshold. Treating $75,000 as the residential cutoff is the most common error, because older rule language and the separate Construction Management registration both reference that figure. The current statute sets the residential and commercial trigger at $50,000. When the number drives a bid or a license decision, confirm it against the live LSLBC page.
• Working outside your classification. The board limits you to the classifications stated on your license, and a licensee may not bid or perform work outside them. Map every scope you intend to perform and add the classifications up front, because adding one later means meeting its requirements and paying its fees.
• Splitting a job to dodge a threshold. The project value counts the entire scope of work, including labor, materials, rentals, and indirect costs, regardless of who pays. Carving one job into smaller contracts to stay under $50,000 or $7,500 is a violation, not a workaround.
• Letting insurance or the financial statement go stale. Residential, home improvement, and mold licenses depend on current insurance certificates, and the financial statement must be current to within twelve months at filing. A lapsed certificate or an outdated statement stalls the application or the renewal. Track both alongside the license anniversary.

Bottom line

Louisiana licenses contractors by the dollar value of the work. Commercial and new residential construction need a license at $50,000 or more, home improvement on existing homes needs a registration from $7,500 up to under $50,000, and mold remediation needs a license at $7,500 or more. Every path runs through the LSLBC: designate a qualifying party, clear the net worth bar ($50,000 commercial and residential, $25,000 home improvement and mold), pass the Business and Law course plus any trade exam, file insurance if you are residential, home improvement, or mold, and submit the application with the capped statutory fees. Renew on the license anniversary for a 1, 2, or 3 year term, and log 6 continuing education hours a year if you are a residential licensee. Get the threshold and the classification right the first time and you hold a credential that works in every Louisiana parish.
