How to Check a Contractor's License in Louisiana

Louisiana takes contractor licensing seriously, but the system is more layered than most states. The Louisiana State Licensing Board for Contractors (LSLBC) handles statewide licensing for projects over $50,000, while a separate home improvement registration covers smaller residential jobs. Add in specialty trades licensed through different boards and local parish requirements, and there's a lot to navigate — especially in a state where hurricane season brings an annual wave of unlicensed storm chasers.

This guide walks through how to verify a contractor's license in Louisiana, what the different license categories mean, and the red flags to watch for before signing a contract.

Does Louisiana require a contractor license?

Yes. Louisiana requires a state license for any contractor performing work valued at $50,000 or more (labor and materials combined). The Louisiana State Licensing Board for Contractors (LSLBC) issues residential and commercial licenses. For smaller residential jobs between $7,500 and $75,000, contractors must hold at minimum a Home Improvement Registration. Both are verifiable at lslbc.louisiana.gov.

The LSLBC requires any contractor performing work valued at $50,000 or more (including labor and materials) to hold a state license. This applies to both residential and commercial projects. The board has been around since 1956 and is one of the more established state licensing systems in the country.

Louisiana divides contractor licenses into two main categories:

• Residential— For contractors building or renovating single-family homes, duplexes, and residential structures. This covers new construction, remodeling, and repair work on residential properties when the project value exceeds $50,000.
• Commercial— For contractors working on commercial buildings, industrial facilities, and public works projects valued over $50,000. Commercial licenses are further broken down into building, highway, heavy, and municipal/public works classifications.

Within each category, contractors can hold licenses for specific classifications and subclassifications that define the type of work they're authorized to perform. A contractor licensed for residential building work cannot automatically take on a commercial highway project — the license has to match the work.

What is the Louisiana Home Improvement Registration and when does it apply?

The Home Improvement Registration is a separate LSLBC credential for contractors doing remodeling, repair, or improvement work on existing residential structures valued between $7,500 and $75,000. It is not a full contractor license. Projects on existing homes between $50,000 and $75,000 fall in an overlap zone — the registration may apply, but any project over $75,000 on an existing home requires a full residential contractor license. Verify both through the LSLBC's search tool.

Here's where Louisiana differs from many states. Projects between $7,500 and $75,000 on existing residential structures fall under a separate system: the Home Improvement Registration. This is not the same as a contractor's license. It's a registration with the LSLBC that covers remodeling, repair, and improvement work on existing homes.

The overlap between $50,000 and $75,000 can be confusing. The key distinction is whether the work is on an existing residential structure (home improvement registration may apply) or involves new construction (full contractor license required). For any project over $75,000 on an existing home, a full residential contractor license is required regardless.

If a contractor is doing a $15,000 bathroom remodel on your existing home, they need at minimum a home improvement registration. If they're building you a new house for $300,000, they need a full residential contractor license. Both are verifiable through the LSLBC.

What information do I need before searching the Louisiana contractor database?

Have at least one of these ready: the contractor's license or registration number (fastest), their full business or personal name, or the parish where they operate. Louisiana law requires contractors to include their license number on all bids, contracts, and advertisements — if a contractor quoting you a $60,000 job cannot produce a license number, that itself is a warning sign.

To look up a contractor in Louisiana, you'll want at least one of these:

• The contractor's license or registration number (fastest and most reliable)
• The contractor's full name or business name
• The parish or city where they operate

Louisiana contractors are required to include their license number on all bids, contracts, and advertisements. If someone gives you a quote for a $60,000 project and can't produce a license number, that tells you everything you need to know.

How do I look up a contractor's license in Louisiana?

Go to lslbc.louisiana.gov/contractor-search/ — the LSLBC's official verification tool. Search by contractor name, license number, or business name, and filter by license type (residential, commercial, or home improvement) if you know it. If you're unsure which category applies, search broadly by name across all types first. The LSLBC can also be reached by phone at (225) 765-2301 to confirm status directly.

Navigate to the Louisiana State Licensing Board for Contractors' verification tool at lslbc.louisiana.gov. This is the official lookup for both licensed contractors and registered home improvement contractors.

The search page lets you look up contractors by name, license number, or business name. You can also filter by license type (residential, commercial, or home improvement). If you're not sure which category to search, start broad and search by name across all types.

What should I look for in a Louisiana contractor's license record?

Confirm the license status is "Active" — any other status means the contractor is not currently authorized. Verify the license type (residential vs. commercial) and specific classifications match your project. Check the expiration date (Louisiana licenses renew annually). Also review insurance, bond information, and any complaints or violations on file — the LSLBC tracks enforcement actions and disciplinary history.

Once you pull up a contractor's record, here's what to look at:

• License status— You want to see "Active." Any other status — expired, suspended, revoked, or inactive — means the contractor is not currently authorized to perform licensed work.
• License type and classifications— Confirm the license type (residential or commercial) and the specific classifications match the work you need done. A contractor licensed for commercial highway work is not authorized for residential building.
• Expiration date— Louisiana contractor licenses must be renewed annually. Check that the license is current and hasn't lapsed.
• Insurance and bond information— The LSLBC requires licensed contractors to maintain general liability insurance and a surety bond. The search results should reflect current coverage.
• Complaints and violations— The board tracks enforcement actions, complaints, and disciplinary history. Any contractor with a pattern of violations is a risk you don't need to take.

Are plumbers, electricians, and HVAC contractors licensed separately in Louisiana?

Yes. Plumbers are licensed through the Louisiana State Plumbing Board (laspb.com), not the LSLBC. HVAC and mechanical contractors are licensed through the Louisiana Mechanical Contractors Licensing Board. Electrical contractors are licensed under a separate LSLBC classification and may also require local licensing. If you're hiring any of these trades directly, search the appropriate board — they will not appear in a standard LSLBC general search.

The LSLBC does not license all contractor types. Several specialty trades are regulated by entirely separate state boards:

• Plumbing— Licensed through the Louisiana State Plumbing Board. Verify at laspb.com.
• Electrical— Licensed through the Louisiana State Licensing Board for Contractors, but under a separate electrical classification. Some electrical work also requires local licensing.
• HVAC and mechanical— Licensed through the Louisiana Mechanical Contractors Licensing Board. Separate verification required.
• Roofing— Roofing contractors working on projects over $50,000 need an LSLBC license. For smaller jobs, the home improvement registration applies. This is a common area where storm chasers operate without proper credentials.

If you're hiring a plumber, electrician, or HVAC technician directly, you'll need to check the appropriate board — not the LSLBC general search. When a general contractor subcontracts specialty work, they're responsible for using properly licensed subcontractors, but it's still worth verifying yourself.

How do I protect myself from unlicensed contractors after a hurricane in Louisiana?

After storms, unlicensed "storm chasers" flood Louisiana every year. The LSLBC and Attorney General's office issue annual warnings about contractor fraud after major hurricanes. Never pay a large upfront deposit to a contractor who approached you door-to-door. Verify any contractor at lslbc.louisiana.gov before signing anything — the search works on your phone and takes under two minutes in your driveway.

Louisiana's hurricane season runs from June through November, and the aftermath of major storms consistently brings a surge of unlicensed contractors. This is not a theoretical risk — it happens every single year. After major hurricanes, the LSLBC and the Louisiana Attorney General's office issue warnings specifically about contractor fraud.

The most common scams follow a predictable pattern:

• Door-to-door solicitation— Contractors showing up uninvited after a storm, offering to start work immediately if you pay a large deposit upfront. Licensed contractors rarely need to go door to door.
• Out-of-state storm chasers— Contractors from other states who flood into Louisiana after hurricanes, do substandard work (or no work at all), and leave before anyone can catch up to them. They typically have no Louisiana license and no local presence.
• Insurance claim manipulation— Contractors who offer to handle your insurance claim for you, inflate the damage estimates, and pocket the difference. This can also leave you personally liable for insurance fraud.
• Cash-only deals with no contract— Any contractor who insists on cash payment and won't provide a written contract is almost certainly unlicensed. Louisiana law requires written contracts for home improvement work.

The urgency after a storm is real, but taking 10 minutes to verify a license can save you thousands. The LSLBC's online search works on your phone — you can check a contractor's license standing in your driveway before they walk through the door.

What else should I check beyond the Louisiana contractor license?

The LSLBC requires licensed contractors to carry general liability insurance and a surety bond — confirm both are current by calling the insurer directly. Louisiana also requires workers' compensation for businesses with one or more employees. Louisiana law mandates a written contract for home improvement work that includes the license or registration number, scope, price, payment schedule, and start and completion dates.

A valid license confirms the contractor has met Louisiana's minimum requirements. Here's what else you should verify:

• General liability insurance— The LSLBC requires licensed contractors to carry liability insurance, and this should appear in their license record. Ask for a certificate of insurance and call the insurer to confirm it's current.
• Workers' compensation— Louisiana requires workers' comp insurance for businesses with one or more employees. If your contractor has workers on your property and no workers' comp, you could be on the hook for injuries.
• Surety bond— Licensed contractors must maintain a surety bond. The bond provides a financial guarantee that the contractor will fulfill their contractual obligations.
• Written contract— Louisiana law requires a written contract for home improvement projects. The contract must include the contractor's license or registration number, a description of the work, the total price, payment schedule, and estimated start and completion dates.
• Complaint history— Beyond the LSLBC records, check the Better Business Bureau and the Louisiana Attorney General's consumer protection division for any filed complaints. A pattern of complaints matters more than a single dispute.

What if I can't find a contractor in Louisiana's licensing system?

Check for a name mismatch first — search by license number if you have it, or try variations of the business name. If you're searching for a plumber or HVAC contractor in the LSLBC, you won't find them — check the appropriate specialty board instead. If the project exceeds $7,500 on an existing home or $50,000 for new construction and the contractor has no valid credential, do not hire them. Call the LSLBC at (225) 765-2301 to confirm status when in doubt.

A blank search result does not always mean the contractor is operating illegally. Here are the most common explanations:

• Name mismatch— The license may be under a different business name or the individual's legal name. Try searching by license number if you have it, or try variations of the business name.
• Wrong board— Plumbers, HVAC contractors, and some electricians are licensed through separate boards. If you're searching the LSLBC for a plumber, you won't find them.
• Project falls below the threshold— If the project is under $7,500 on an existing home, neither a license nor home improvement registration is required at the state level. Local requirements may still apply.
• They're genuinely unlicensed— If the project value exceeds the thresholds and the contractor doesn't appear in any relevant database, do not hire them. Unlicensed contracting in Louisiana is a criminal offense, and hiring an unlicensed contractor leaves you with limited legal recourse if the work is defective.

When in doubt, call the LSLBC directly at (225) 765-2301. They can confirm whether a contractor is licensed, registered, or neither.

The bottom line

Louisiana's contractor licensing system has more layers than most states, but that's actually a good thing for consumers. The $50,000 threshold for full licensing, the home improvement registration for mid-range projects, and the separate specialty boards create multiple checkpoints where you can verify that the person working on your property is qualified and accountable.

Use the LSLBC contractor search to confirm the license is active, the classifications match your project, and the insurance and bond are current. For specialty trades, check the appropriate separate board. And if you're dealing with post-storm repairs, slow down and verify before you sign anything — the contractor who pressures you to skip the license check is the one most likely to disappear with your deposit.
