Introduction to Louisiana Contractor Licensing

Louisiana regulates contractors through the Louisiana State Licensing Board for Contractors (LSLBC), the single state agency responsible for licensing and oversight of the contracting industry. The LSLBC administers licensing for commercial contractors, residential builders, home improvement registrants, and mold remediation contractors across the state.

Unlike states that split oversight between multiple boards, Louisiana consolidates all contractor licensing under the LSLBC. The board enforces the Louisiana Contractors Licensing Law (Louisiana Revised Statutes Title 37, Chapter 24), which establishes the monetary thresholds, classification system, and penalties that govern the industry.

The key thresholds you need to know: commercial projects valued at $50,000 or more require a commercial contractor license, residential construction exceeding $75,000 requires a residential license, and home improvement work between $7,500 and $75,000 requires a home improvement registration. Specialty areas like hazardous materials and mold remediation have their own thresholds starting at just $1. Getting these thresholds wrong can result in criminal penalties, voided contracts, and the inability to collect payment for work performed.

Types of Contractor Licenses

The LSLBC issues four distinct license/registration types based on the nature and value of the work. Each type has its own monetary threshold, classification system, and requirements.

Commercial Contractor License

A commercial contractor license is required for any project valued at $50,000 or more (labor and materials combined) on property used for commercial purposes. "Commercial purpose" covers all construction except residential structures with no more than two attached or incorporated dwelling units.

Commercial licenses are organized under eight major classifications:

  1. Building Construction — structures, modifications, and additions for shelter, protection, or commercial use
  2. Highway, Street, and Bridge Construction — road infrastructure and related work
  3. Heavy Construction — large-scale industrial projects, dredging, and heavy civil work
  4. Municipal and Public Works Construction — utility infrastructure including water lines and sewer systems
  5. Electrical Work — electrical systems installation and maintenance
  6. Mechanical Work — HVAC, refrigeration, and mechanical systems
  7. Plumbing — plumbing systems installation and repair
  8. Hazardous Materials — asbestos, lead paint abatement, hazardous waste, and underground storage tanks

Each major classification contains numerous subclassifications for specialized trades (e.g., drywall, roofing, industrial piping, landscaping). There are also specialty classifications that fall outside the major categories, such as coverings and linings, water well drilling, and leak repairs. A complete list of all classifications is available on the LSLBC Exams & Classifications page.

Note: Subcontractors and specialty trades performing commercial work valued at $50,000 or more also require a license. Electrical, mechanical, and plumbing subcontractors have a lower threshold of $10,000 including labor and materials.

Residential Construction License

A residential construction license is required for residential projects exceeding $75,000 (labor and materials). "Residential structure" means a building used primarily as a residence or dwelling unit.

Important change effective January 1, 2026: Only licensees holding the Residential Construction or Residential Roofing classifications may perform residential roof work valued at $7,500 or more. Any person who advertises, solicits, or submits a price for roofing work on a residential structure at that threshold must hold one of these two classifications.

Home Improvement Registration

Home improvement registration is required for renovation, repair, remodeling, or improvement work on preexisting residential structures when the project value is between $7,500 and $75,000 (labor and materials). This covers reconstruction, alteration, renovation, repair, modernization, conversion, improvement, removal, or demolition of existing residential structures.

Contractors who already hold a valid commercial or residential license with the LSLBC are exempt from the home improvement registration requirement.

Mold Remediation License

A mold remediation license is required for mold remediation projects valued at $1 or more. This covers removal, cleaning, sanitizing, demolition, or other treatment of mold contamination, including preventative measures. The qualifying party must have completed at least 24 hours of mold remediation training and 4 hours of training in unfair trade practices and consumer protection law from a board-approved training provider.

Hazardous Materials

Asbestos removal/abatement, hazardous waste handling, lead-based paint abatement/removal, and underground storage tank work all require licensing at a threshold of $1 or more. Asbestos contractors must additionally furnish proof of certification from the Louisiana Department of Environmental Quality.

Licensing Requirements

Louisiana's licensing requirements center on designating a qualified individual, passing examinations, demonstrating financial capacity, and meeting insurance obligations.

Qualifying Party

Every applicant must designate a qualifying party — the individual responsible for the company's construction operations and for passing the required examinations. The qualifying party can be:

  • A sole proprietor or their spouse
  • An employee who has been in full-time employment for at least 120 consecutive days immediately preceding the application
  • An officer or manager of the company

The qualifying party must sign a notarized affidavit and is the individual who sits for the required exams.

Experience Requirements

Louisiana does not impose a minimum number of years of experience for most contractor licenses. There is no formal experience prerequisite for commercial, residential, or home improvement applicants. The primary gatekeeping mechanism is the examination requirement.

The exception is mold remediation, which requires the qualifying party to have completed specific training hours (24 hours in mold remediation plus 4 hours in consumer protection law).

Financial Requirements

All applicants must submit a notarized financial statement showing a minimum net worth of $10,000. The financial statement must be:

  • Current within 12 months of the application filing date
  • Prepared by a CPA, accountant, or bookkeeper
  • Signed by the applicant before a notary public

If you cannot demonstrate the required net worth, you may furnish a surety bond, letter of credit, or other security acceptable to the board in the amount of the net worth requirement ($10,000) plus any negative net worth.

The LSLBC provides a financial statement form on their website.

Background Check

The LSLBC reviews the criminal background of all applicants, including individual owners, officers, managers, and qualifying parties. A criminal conviction does not automatically disqualify an applicant, but convictions related to the following may result in denial:

  • Fitness or ability to act as a contractor
  • Handling and accounting of money
  • False swearing or record keeping

If you have concerns about your criminal history, you can request a pre-application determination from the LSLBC. The board will provide a written response within 45 days informing you whether you are disqualified. The cost for this review is included in the $60 Background Financial Investigation fee. Visit the LSLBC Criminal Conviction page for details.

Business Registration

Before applying for a contractor license, you must register your business with the Louisiana Secretary of State. This applies to LLCs, corporations, and other business entities operating in Louisiana.

Application Process

The LSLBC handles all applications through its online application portal. Here is the step-by-step process:

Step 1: Determine Your License Type and Classifications

Review the Types of Licenses and Exams & Classifications pages to identify which license type and specific classifications apply to the work you intend to perform.

Step 2: Register Your Business

Ensure your business entity is registered with the Louisiana Secretary of State before submitting your application.

Step 3: Prepare Required Documents

  • Notarized financial statement (current within 12 months, showing minimum $10,000 net worth)
  • Proof of general liability insurance (for residential, home improvement, and mold applicants)
  • Proof of workers' compensation insurance (if you have employees)
  • Qualifying party's notarized affidavit
  • Background information for all owners, officers, managers, and qualifying parties

Step 4: Submit the Application and Pay Fees

Complete the application through the LSLBC online portal. Pay the non-refundable application fee ($100 for one classification, $195 for two) plus the $60 Background Financial Investigation fee.

Step 5: Pass the Required Examinations

After your application is accepted, schedule and pass both the Business and Law exam and the trade-specific exam for each classification. See the Examination Requirements section below for details.

Step 6: Submit Insurance Certificates

After passing your exams, submit proof of insurance to the LSLBC at insurance@lslbc.louisiana.gov. Residential, home improvement, and mold remediation applicants must provide certificates before the license can be issued.

Step 7: Receive Your License

Once all requirements are satisfied, the LSLBC issues your license. Processing times vary, but plan for several weeks after all documents and exam results are received.

Examination Requirements

Louisiana requires two examinations for contractor licensure: a Business and Law exam and a trade-specific exam for each classification sought.

Business and Law Exam

  • Format: Open-book, multiple choice
  • Duration: 1 hour
  • Topics: Louisiana licensing law, bidding procedures, contract management, job safety, lien laws, and tax fundamentals
  • Passing score: 70% or higher
  • Fee: $175 per attempt

Trade Exam

  • Format: Open-book, multiple choice, computer-based
  • Questions: 30 to 115 questions depending on classification
  • Duration: Varies by classification (e.g., 1 hour 15 minutes for Heavy Construction)
  • Passing score: 70% or higher
  • Fee: $175 per classification per attempt

Exam Provider

All examinations are administered by PSI Services LLC (PSI). Exams are computer-based and taken in person at PSI testing centers. You can view exam content outlines and study reference lists at PSI's Louisiana contractor exam page.

Retake Policy

If you do not pass an exam, you must wait a mandatory 30 days before retaking it. There is no limit on the number of attempts, but you must pay the exam fee each time.

NASCLA Accredited Examination

Louisiana accepts the NASCLA Accredited Examination for Commercial General Building Contractors. If you hold a passing NASCLA score, it can be applied toward your Louisiana commercial building construction classification. The NASCLA exam is also accepted in Alabama, Arkansas, Georgia, Mississippi, North Carolina, South Carolina, Tennessee, Utah, Virginia, and several other states.

License Fees and Costs

Below is a summary of the fees associated with obtaining and maintaining a Louisiana contractor license. All fees are non-refundable.

Commercial and Residential License Fees

Fee Type Amount
Application fee (1 classification) $100
Application fee (2 classifications) $195
Each additional classification $95
Background Financial Investigation fee $60
Exam fee (per exam, per attempt) $175
Annual renewal fee $100

Home Improvement Registration Fees

Fee Type Amount
Application fee (domiciled in Louisiana) $75
Application fee (domiciled out of state) $475
Background Financial Investigation fee $60
Annual renewal fee $100

Total Estimated Startup Costs

For a typical commercial or residential applicant with one classification, expect to spend approximately $510 to $610 on application and exam fees alone (application + background investigation + two exams). Adding a second classification raises the total to roughly $780 to $880. These figures do not include insurance premiums, surety bonds (if needed), or exam preparation materials.

For a current and complete fee schedule, visit the LSLBC Fee Schedule Worksheet.

Insurance and Bond Requirements

Insurance requirements vary by license type. The LSLBC does not require proof of insurance for commercial contractor applicants, but residential, home improvement, and mold remediation applicants must provide coverage before a license or registration can be issued.

General Liability Insurance

License Type Minimum GL Coverage
Residential Construction $100,000
Home Improvement Registration $100,000
Mold Remediation $50,000
Commercial Not required by LSLBC

Workers' Compensation Insurance

Home improvement registrants and residential contractors must submit certificates evidencing workers' compensation coverage in compliance with Title 23 of the Louisiana Revised Statutes if they have employees. Even if you have no employees, you may still need to provide proof of an exemption or waiver.

Surety Bond

A surety bond is not universally required. However, applicants who cannot demonstrate the minimum net worth of $10,000 through their financial statement may post a surety bond, letter of credit, or other security in the amount of the net worth requirement plus any negative net worth. The bond amount is typically $10,000.

Maintaining Insurance

You must maintain continuous insurance coverage for the duration of your active license or registration. Updated insurance certificates must be provided to the LSLBC at each renewal. Lapsed coverage can result in license suspension.

License Renewal

Louisiana contractor licenses expire on the anniversary of the original issue date and must be renewed annually. The LSLBC sends renewal notices by email to the address on file at 60 days and again at 15 days before your expiration date.

Renewal Process

  • Renewal becomes available 60 days before the expiration date
  • Renew through the LSLBC online portal
  • You may choose a one-year, two-year, or three-year renewal period
  • Submit current insurance certificates (for residential, home improvement, and mold licenses)
  • Submit an updated financial statement if requested

Renewal Fees

The annual renewal fee is $100 for all license types.

Late Renewal

If you renew more than 15 days after expiration, the board may impose a late penalty of up to $50 in addition to the standard renewal fee. Renewal notices are sent from licensing@lslbc.gov, so make sure that address is whitelisted in your email.

Expired Licenses

If your license has been expired for more than one year, you cannot renew. You must reapply for a new license, which means going through the full application and examination process again.

Continuing Education

Residential contractors must complete a minimum of 6 hours of continuing education annually by December 31 each year. The CE must be completed through a board-approved provider. There are no specific course category requirements — you may choose topics that are most relevant to your work. Maintain a copy of your completion certificate for five years, as the board may request it.

Exemption: If a residential contractor also holds a valid commercial license in one or more major classifications (Building Construction, Highway/Street/Bridge, Heavy Construction, or Municipal/Public Works), the 6-hour CE requirement is considered met.

There are no continuing education requirements for commercial contractors, home improvement registrants, or mold remediation contractors.

For questions about CE, contact the LSLBC at ce@lslbc.gov.

Reciprocity with Other States

Louisiana maintains examination endorsement and reciprocity agreements with several states. These agreements allow out-of-state contractors to receive credit for approved classifications without retaking the Louisiana trade exam.

States with Reciprocity Agreements

The LSLBC has reciprocity or exam endorsement agreements with the following states (verify current status with the LSLBC, as agreements are updated periodically):

  • Alabama
  • Arkansas
  • Georgia
  • Kentucky
  • Mississippi
  • North Carolina
  • Ohio
  • South Carolina
  • Tennessee
  • Texas
  • Utah
  • Virginia

For complete details on reciprocity by classification, visit the LSLBC Reciprocity page or download the reciprocity guide (PDF).

What Reciprocity Covers

Reciprocity typically waives the trade-specific exam for equivalent classifications. However, all applicants — regardless of reciprocity status — must still pass the Louisiana Business and Law exam. This exam covers Louisiana-specific statutes, lien laws, and contracting regulations that differ from other states.

To qualify for reciprocity, you must have passed the trade exam in the other state without waivers, exemptions, or grandfathering.

NASCLA Accredited Examination

Louisiana accepts the NASCLA Accredited Examination for commercial general building contractors. Holding a passing NASCLA exam score can streamline licensing in Louisiana and in other NASCLA-member states including Alabama, Arkansas, Arizona, Georgia, Mississippi, Nevada, North Carolina, Oregon, South Carolina, Tennessee, Utah, the U.S. Virgin Islands, Virginia, and West Virginia.

How to Verify a Contractor's License

Before hiring a contractor in Louisiana, verify their license status through the LSLBC's free online lookup tools:

The search results display the contractor's license status (active, expired, or revoked), classifications held, financial limits, and any disciplinary history.

What to Check

  • Active status — confirm the license has not expired or been revoked
  • Correct classification — ensure the contractor is licensed for the type of work you need
  • Insurance coverage — verify current insurance is on file
  • Disciplinary actions — check for complaints, violations, or enforcement actions

Penalties for Working Without a License

Louisiana takes unlicensed contracting seriously. The penalties are both criminal and civil, and the consequences can be financially devastating.

Criminal Penalties

Under Louisiana Revised Statutes § 37:2160, engaging in the business of contracting without a license is a misdemeanor. Penalties include:

  • Fines up to $500 per day of violation
  • Up to 3 months in prison
  • Or both

The district attorney in the jurisdiction where the violation occurs has sole authority to prosecute these cases. Fines collected are remitted to the Contractor's Educational Trust Fund under R.S. 37:2162(J).

Contract Nullity

Perhaps the most severe consequence is that contracts with unlicensed contractors are considered absolute nullities under Louisiana law. Under Louisiana Civil Code Article 2030, an absolutely null contract is deemed to have never existed. This means:

  • The contractor cannot enforce the contract or collect payment
  • The parties must be restored to the situation that existed before the contract was made
  • Any person — including the homeowner — can invoke the nullity at any time
  • The court may declare the nullity on its own initiative

Louisiana courts have consistently upheld this principle. If you perform work without a license in situations where one is required, you risk being unable to collect for the work you have already completed.

Administrative Penalties

Under R.S. 37:2158, the LSLBC can issue cease and desist orders, revoke or suspend licenses, and pursue debarment actions against contractors who violate the licensing law. The board's enforcement division actively investigates complaints from consumers, competing contractors, and other agencies.

Frequently Asked Questions

Do I need a license for small residential projects under $7,500?

No. The LSLBC does not require a license or registration for residential work valued below $7,500 (labor and materials). However, some Louisiana municipalities may have their own local licensing requirements that apply at lower thresholds. Always check with your local parish or city government.

Does Louisiana require experience to get a contractor license?

For most license types, no. Louisiana does not mandate a minimum number of years of field experience. The primary requirement is passing the Business and Law exam and the relevant trade exam. The exception is mold remediation, which requires specific training hours.

How long does the licensing process take?

Timeframes vary, but most applicants should plan for 4 to 8 weeks from application submission to license issuance, assuming all documents are in order and exams are passed promptly. Delays are common when financial statements or insurance certificates are incomplete.

Can I operate in Louisiana with an out-of-state license?

Not automatically. You must apply for a Louisiana license through the LSLBC. If your state has a reciprocity agreement with Louisiana, you may be able to skip the trade exam, but you will still need to pass the Louisiana Business and Law exam and meet all other application requirements.

What happens if my license expires?

You have a 15-day grace period after expiration to renew without penalty. After 15 days, a late fee of up to $50 applies. If your license has been expired for more than one year, you cannot renew and must apply for a new license from scratch.

Are there separate licenses for electricians and plumbers at the local level?

Yes. While the LSLBC handles statewide contractor licensing, many Louisiana parishes and municipalities require separate trade-specific licenses for electricians, plumbers, and mechanical contractors working within their jurisdictions. The LSLBC license does not replace local licensing requirements.

Conclusion

Louisiana's contractor licensing system is administered by a single board — the Louisiana State Licensing Board for Contractors — which simplifies the process compared to states with multiple licensing authorities. The critical steps are understanding which license type and classifications apply to your work, passing the required examinations through PSI, meeting the financial and insurance requirements, and maintaining your license through timely renewals.

The monetary thresholds ($50,000 for commercial, $75,000 for residential, $7,500 for home improvement) are your first checkpoint. If your projects exceed these values, licensing is mandatory — and the consequences of operating without one range from criminal prosecution to having your contracts declared void.

For the most current information, always refer directly to the LSLBC website or contact the board at (225) 765-2301. The Contractors Licensing Law and Rules & Regulations (Blue Book) is the definitive reference for all Louisiana contractor licensing requirements.
