Verify a Louisiana Contractor Before You Sign, Pay or Let Work Begin
The State of Louisiana contractors license lookup is operated by the Louisiana State Licensing Board for Contractors, commonly called LSLBC. Use the official public search to confirm that the contractor you are dealing with appears under the correct legal name, credential type and classification before relying on a bid, contract, advertisement or old license certificate.
A useful check goes beyond finding a company name. Confirm the exact license or registration number, current record, classifications and expiration information, then review public violations, the Louisiana business record when relevant, insurance requirements and any local permit requirements that apply to the project.
Louisiana Contractor License Lookup: Quick Answer
Open the official LSLBC contractor search and use the license or registration number when you have it. The general public search also supports fields such as license type, company name, first and last name, phone number and location, while LSLBC’s advanced search adds filters such as parish, contractor type, classification and qualifying party.
LSLBC specifically states that its contractor-search results contain currently licensed or registered contractors. This matters when an old contractor number produces no result: a blank search does not by itself prove that the contractor was never licensed. Recheck the number, legal name and search route, then contact LSLBC if a contractor claims to hold a current credential that you cannot confirm.
The Board also warns that public search information is provided as a courtesy and may not reflect every recent change or update. If the result affects a major payment, permit, legal requirement or high-value contract and something in the record is unclear, confirm the issue directly with LSLBC.
Match the legal contractor identity
The name on the bid and contract should make sense when compared with the official LSLBC record. Louisiana licensing guidance requires licensed or registered contractors to conduct contracting business in the name appearing in the Board’s official records.
Confirm the classification
A current credential does not automatically authorize every kind of construction. Check the classification or subclassification against the work actually being advertised, bid or performed.
Review violations separately
LSLBC maintains a separate contractor-violations database. Use it when a hiring or compliance decision requires more than a simple current-status lookup.
How to Verify a Louisiana Contractor License or Registration
Use this workflow before signing a construction agreement, paying a deposit, accepting a subcontractor, relying on a roofing credential or approving a contractor for a regulated project.
Get the contractor’s exact legal name and credential number
Ask for the business or individual name that appears in the LSLBC record and the contractor’s license or registration number. Compare that information with the estimate, contract, invoice and payment instructions.
Open the official Louisiana contractor search
Use the LSLBC public search rather than relying on a private directory, advertisement, social profile or photograph of a license certificate. The Board provides several public search routes.
Search by license or registration number when possible
A number search is usually the fastest way to avoid confusing businesses with similar names. Check every digit before deciding that no record exists.
Compare the full matching record
Confirm the contractor identity, credential type, license or registration number, current status or current-looking record, issue and expiration information where displayed, classifications and qualifying-party information where available.
Match the classification to the actual project
Check whether the classification covers the work being offered. Roofing, electrical, mechanical, plumbing, pools, mold remediation and other specialty scopes can have requirements that are not established merely by finding an active company record.
Complete the second-layer checks before hiring
Review the LSLBC violations database, compare the legal business entity through the Louisiana Secretary of State when applicable, request current insurance evidence for covered license types, and confirm any parish or municipal permit requirements for the project.
Save the contractor name, license or registration number, credential type, classification, expiration information, date checked and official page used. Recheck the record if the project is delayed or the contractor changes the contracting entity.
Which Louisiana Contractor Search Should You Use?
LSLBC offers more than one search form. Choose the route that matches the information you already have instead of using a broad company-name search when a precise identifier is available.
| Search method | Best information to use | Useful when | What to watch for |
|---|---|---|---|
| License number | Exact LSLBC license or registration number. | The contractor has provided a credential number on a bid, contract or certificate. | Transposed digits, stale paperwork or a number belonging to another entity. |
| Company or individual name | Legal contractor name rather than only a marketing name. | You have no license number. | Similar names, abbreviations and DBA names that differ from the Board record. |
| General public search | License type, number, company, person, phone or address information. | You know contact or location details but not the exact license number. | Matching the correct entity when several records appear. |
| Advanced search | Company, individual, number, city, parish, type, classification or qualifier. | You need to narrow a broad search or find contractors by classification. | Using too many filters and accidentally excluding the correct record. |
| Qualifying party | Qualifier first and last name. | You know the person who qualifies a licensed contractor for a classification. | A qualifying party is not automatically the owner of the contractor license. |
| Find License Near Me | License type, ZIP code, city, state and search distance. | You need licensed contractors around a Louisiana location. | Proximity does not replace classification, status and violation checks. |
What to Check in a Louisiana Contractor Record
The lookup is most useful when you treat identity, credential type and scope of authority as separate questions.
Legal business or individual name
Compare the official name with the party signing your contract and receiving payment. If the names do not align, ask the contractor to explain the legal relationship before proceeding.
License or registration number
Match the exact number supplied by the contractor. Do not assume a number copied from an advertisement belongs to the business actually performing your work.
Commercial, Residential, Home Improvement or Mold
Louisiana uses different license and registration categories. The correct category depends on the property, project value and work being performed.
Classification or subclassification
Classification determines the work covered by the license. An active contractor credential should not be treated as unlimited authority to perform every construction specialty.
Issue and expiration information
Review the dates shown in the current record and verify again before work begins if the expiration date is close or the project has been delayed.
Public violations
Search the separate violations database for published allegations, hearing information and Board actions when a deeper compliance check is appropriate.
Louisiana Contractor License vs Registration: Know the Credential Type
Searchers often use the word “license” for every contractor record, but Louisiana distinguishes several categories. Understanding the category prevents a false match.
| Credential | Typical use | Important verification point |
|---|---|---|
| Commercial License | Covered commercial construction and specialty work meeting applicable project thresholds. | Confirm the classification covers the commercial scope being bid or performed. |
| Residential License | Covered residential construction and higher-value residential work. | Check Residential Construction or the correct residential subclassification. |
| Home Improvement Registration | Qualifying improvement work on existing residential structures within the home-improvement range. | Do not treat registration alone as authority for structural work or residential roofing. |
| Mold Remediation License | Covered mold-remediation projects meeting the state threshold. | Verify the Mold Remediation credential rather than relying on a general remodeling license. |
LSLBC describes the qualifying party as the natural person designated by the contractor to represent the contractor for licensing-law purposes and to satisfy applicable classification, examination or credential requirements. The qualifier is not automatically the owner of the license.
Louisiana Contractor License Thresholds and Project Rules
Louisiana licensing depends on both the type of work and project value. Labor and materials are generally considered when determining the applicable project amount, so a homeowner should not look only at the contractor’s labor charge.
| Project or work type | Current rule to know | Credential check | Practical warning |
|---|---|---|---|
| General commercial construction | $50,000 or more under current LSLBC guidance. | Commercial license with the classification covering the work. | Include labor and materials when evaluating the project amount. |
| Commercial electrical, mechanical or plumbing | LSLBC public guidance describes the threshold as work exceeding $10,000; 2026 enacted statutory language uses $10,000 or more for these defined trades. | Applicable Commercial trade classification and any separate trade credential required by law. | If a project is exactly at a statutory boundary, confirm the requirement directly with LSLBC. |
| Hazardous-material classifications | $1 or more for covered asbestos, hazardous waste, lead-abatement/removal and underground-storage-tank work. | Appropriate hazardous-material classification. | Do not assume a small dollar value removes the licensing requirement. |
| New residential construction | 2026 enacted law uses $50,000 or more for new residential structures. | Residential Construction license. | Some older LSLBC wording uses “exceeding $50,000”; confirm exact-boundary projects with the Board. |
| Home improvement | The Home Improvement category covers qualifying work beginning at $7,500 and below the Residential-license level. | Home Improvement registration or the appropriate Residential credential depending on scope and value. | A contractor operating only under Home Improvement registration should not be treated as authorized for structural or roofing work. |
| Mold remediation | $7,500 or more. | Mold Remediation license. | Routine cleaning is not the same thing as regulated mold remediation. |
| Residential swimming pool | LSLBC classification guidance applies the pool classification when labor and materials exceed $7,500. | Residential Swimming Pools classification where required. | Confirm whether the prime contractor holds the pool classification or is using a properly licensed subcontractor. |
| Residential roofing | $7,500 or more beginning January 1, 2026. | Residential Roofing or Residential Construction classification. | An ordinary Home Improvement registration alone is not the correct proof for covered residential roofing. |
Louisiana’s 2026 enacted legislation changed portions of the licensing definitions while some public guidance pages may still use older “exceeds” wording. If your total project is exactly $10,000, $50,000 or another legal boundary, confirm the requirement with LSLBC before bidding, contracting or starting work.
Important Louisiana Contractor Changes in 2026
Two 2026 changes are especially important when you verify residential contractors: the new residential-roofing classification rule and the higher insurance requirement introduced by Act 757.
Residential roofing now has a specific $7,500 rule
Louisiana Revised Statutes §37:2156.4 requires a person who advertises, solicits, offers, bids, quotes, supervises or performs covered residential roofing work valued at $7,500 or more to hold the Residential Roofing or Residential Construction classification.
For a homeowner, the practical check is simple: do not stop after finding an active Louisiana contractor record. Open the classification information and verify that the contractor has Residential Roofing or Residential Construction authority for a covered roof project.
Liability-insurance minimum increased to $500,000
LSLBC’s June 25, 2026 memorandum states that Residential Construction and its subclassifications, Mold Remediation and Home Improvement applicants must provide workers’ compensation evidence in compliance with Louisiana law and liability insurance of at least $500,000, or qualifying liability-trust protection of at least $500,000.
The proof must identify the licensee, insurer and broker information, policy number and coverage dates, show no exclusions for the licensed scopes, cover at least six months and list LSLBC as a certificate holder. The Board’s memorandum warns that failure to meet the new standards will result in suspension of licensure.
Some older LSLBC FAQ and checklist material still displays earlier $100,000 or $50,000 liability amounts. For current post-August 1, 2026 requirements, use LSLBC’s dated Act 757 memorandum and confirm any remaining conflict with the Board.
Before Hiring: Check the License, Contract, Insurance and Permits
A contractor lookup is an identity and licensing check. A safe hiring file also needs a written project scope, the correct contracting entity, required insurance and local permit information.
Verify before signing
Record the exact credential number, legal name, type and classification shown by LSLBC. Recheck before work if significant time passes between the estimate and start date.
Make sure the written agreement identifies the contractor
Louisiana law requires agreements for contracting services that require licensure or registration to contain specified information, including contractor names, addresses, license number, description of work, price information and signatures.
Request current certificates when required
The written-contract statute also requires current insurance certificates when insurance is a condition of the contractor’s license. Compare the insured name with the legal contractor you are hiring.
Match the work, not just the company
A contractor licensed for one category should not be assumed to hold every specialty classification. Verify roofing, pool, electrical, mechanical, plumbing, mold or other specialty authority separately when applicable.
Resolve name mismatches before paying
If the contractor record, contract and payment recipient show different legal names, ask for an explanation and supporting documentation before sending a deposit.
State licensure does not replace permits
Parish and municipal permits, inspections and local requirements are separate from the state contractor license. Confirm the local permit process for the property where work will occur.
Louisiana law prohibits contractors from interpreting property-insurance policy coverage for an insured or acting as a public adjuster on the insured’s behalf. A roofing or repair contractor can estimate construction work, but insurance-coverage interpretation and claim adjustment are separate regulated activities.
LSLBC Contractor Lookup vs Louisiana Business Search
Contractor licensure and business registration answer different questions. Checking both can help when the contractor is an LLC, corporation or another registered business entity.
| Official search | What it helps verify | Useful search fields | What it does not replace |
|---|---|---|---|
| LSLBC Contractor Search | Louisiana contractor license or registration information, type and classifications. | License number, legal name, contractor type, parish, classification and qualifying party depending on search route. | Separate Secretary of State business filing or local permit checks. |
| Louisiana Secretary of State Business Search | Business-entity filing information and legal business identity. | Entity name, charter or trade-registration number, officer name or agent name. | An LSLBC contractor license, registration or classification. |
LSLBC’s own FAQ states that registration with the Louisiana Secretary of State does not qualify a company to perform construction work that requires an LSLBC license or registration.
LSLBC states that a licensee must bid, contract and perform work in the name appearing in the Board’s official records and that the Board does not recognize a DBA, assumed name or fictitious name as the licensed legal business entity.
How to Check Louisiana Contractor Violations
LSLBC publishes a separate violations database. It includes fields such as contractor, location, hearing date, job number, allegation and action taken.
Do not judge from the contractor name alone
Open the relevant row and read the allegation and action taken. A continuance, settlement, fine, suspension, revocation or other action has a different meaning and should not be treated as interchangeable.
Wrong classification matters
Published LSLBC enforcement records include cases involving bidding or work without the proper license or classification. This is why classification verification belongs in the hiring workflow.
A violation search is not the same as filing a complaint
Use the violations database to review published Board actions. Use LSLBC’s consumer complaint route when you need to report a current contractor problem or suspected unlicensed activity.
No Louisiana Contractor License Result Found? Troubleshoot It
LSLBC says only currently licensed or registered contractors appear in its contractor-search results. Use the steps below before deciding what a missing result means.
| Problem | Possible reason | What to do |
|---|---|---|
| No result by number | Wrong digit, stale number or credential not currently appearing in the public search. | Check every digit, then search by the exact legal contractor name. |
| No result by company name | The advertising name or DBA differs from the legal LSLBC name. | Ask the contractor for the exact licensed name and credential number. |
| Several similar names appear | Common business or individual name. | Narrow by number, parish, city, classification, type or qualifying party. |
| Only a Secretary of State record appears | The company has a Louisiana business filing but you have not found a matching current contractor credential. | Request the LSLBC license or registration number and verify it separately. |
| Contractor shows an old certificate | The credential may have expired or the record may have changed. | Use the current public database rather than relying on the old paper certificate. |
| Contractor appears but classification does not fit | The contractor holds authority for different work. | Compare the project scope with LSLBC’s current classification list before proceeding. |
Contact the Board if a contractor claims the license is active but you cannot locate it, the legal name does not match, a classification is unclear or a recently renewed credential appears inconsistent with the contractor’s documentation.
How to Find a Licensed Louisiana Contractor Near You
LSLBC provides a Find License Near Me tool for people who do not already have a contractor in mind.
Search by ZIP, city and distance
The official tool allows you to select a license type and use ZIP code, city, state and maximum distance information to find nearby records.
Near you does not mean right for the job
After finding nearby contractors, open each record and check credential type, classification and current status. Then review violations and the legal business identity before hiring.
Louisiana Contractor Renewal, Expiration and Formal Verification
Contractors checking their own credential need a different workflow from homeowners performing a public lookup.
Renewal opens before expiration
LSLBC says a license cannot be renewed until 60 days before expiration. Renewal notices are sent to the email address on file approximately 60 days and again 15 days before the expiration date.
One-, two- or three-year options can apply
The Board’s renewal page describes one-, two- and three-year renewal options. Separate statutory restrictions can apply to licenses dependent on insurance or certifications, so follow the renewal options actually presented for your credential.
Reapplication becomes necessary
LSLBC states that a license cannot be renewed after it has been expired for one year. At that point, the contractor must submit a new application.
Use the contractor portal for account actions
The public lookup is for verification. Licensed contractors and applicants use the secure contractor portal for renewal, application and account-related actions.
Formal license verification is a different service
A Louisiana contractor who needs official verification for licensure in another state should use the Verification of License Request available through the contractor portal rather than relying on a public-search screenshot.
Covered licensees must keep required coverage current
Residential, Home Improvement and Mold Remediation credentials are subject to insurance requirements. Review the 2026 Act 757 memorandum when preparing current insurance documentation.

Louisiana Contractor License Lookup FAQs
How do I verify a Louisiana contractor license online?
Use the Louisiana State Licensing Board for Contractors public search. Search by license or registration number when possible, open the matching record, and confirm the contractor’s legal name, credential type, classification, current record and expiration information before hiring or paying.
What can I search by in the Louisiana contractor lookup?
LSLBC provides public search routes using contractor name, license number, city or town, parish, contractor type and qualifying party. The broader public and advanced searches can also use fields such as classification, phone number and location information.
Does no search result mean a Louisiana contractor was never licensed?
No. LSLBC says only currently licensed or registered contractors appear in its contractor-search results. A blank result can also come from a wrong number, different legal business name or search mismatch, so retry the search and contact LSLBC if the contractor claims a current credential.
What should I check besides whether the contractor appears active?
Confirm the credential belongs to the exact contractor you are hiring, check the license or registration type, match the classification to the project, review expiration information, search public violations, compare the legal business entity when appropriate, request required insurance evidence and confirm local permits.
When is a Louisiana commercial contractor license required?
Current LSLBC guidance requires a Commercial license for general commercial projects valued at $50,000 or more including labor and materials. Different thresholds apply to electrical, mechanical, plumbing and hazardous-material work, so verify the project type as well as the dollar amount.
What is the difference between a Home Improvement registration and Residential license?
Home Improvement registration is used for qualifying work on existing residential structures within the applicable home-improvement range, while Residential licensing covers residential construction and higher-value or otherwise regulated residential scopes. A Home Improvement registration alone should not be treated as authority for structural work or residential roofing.
What changed for Louisiana residential roofing in 2026?
Beginning January 1, 2026, Louisiana law requires a contractor who advertises, solicits, offers, bids, quotes, supervises or performs covered residential roofing work valued at $7,500 or more to hold the Residential Roofing or Residential Construction classification.
What changed for Louisiana contractor insurance on August 1, 2026?
LSLBC’s 2026 Act 757 memorandum requires affected Residential Construction and subclassification, Mold Remediation and Home Improvement applicants to provide workers’ compensation evidence and at least $500,000 in liability insurance or qualifying liability-trust protection, with additional policy and certificate requirements.
Is a Louisiana Secretary of State business record the same as a contractor license?
No. The Secretary of State search verifies business-filing information, while the Louisiana State Licensing Board for Contractors verifies contractor licenses, registrations and classifications. A business filing does not replace an LSLBC credential when contractor licensure or registration is required.
How do I check violations or report a contractor problem in Louisiana?
Use LSLBC’s Contractor Violations database to review published enforcement information. To report a current contractor problem or suspected unlicensed activity, use the dedicated consumer complaint resources instead of the general contact form.
Verify the Contractor, Classification and Legal Business Before Work Starts
Start with the official Louisiana State Licensing Board for Contractors search and match the exact contractor to the current state record. Then confirm that the credential type and classification fit the project, review violations, compare the legal business entity when appropriate and request the insurance documentation required for the contractor’s category.
For residential work in 2026, pay special attention to the $7,500 residential-roofing rule and the Act 757 insurance changes effective August 1, 2026. If a project sits exactly at a licensing threshold or the official pages appear inconsistent, contact LSLBC before relying on an assumption.
