How to Start a Contracting Business in Louisiana

Start with the project value, not the trade name

Almost every Louisiana licensing mistake begins the same way: an owner decides what kind of contractor they are, then goes looking for the matching licence. LSLBC works the other way round. The Board publishes four basic licence types, and which one you need is set by the property type and by the total project value, which the Board defines as the cost of labour and materials combined "no matter who supplies the materials".

The commercial side has three tiers. A Commercial licence is required for commercial projects with a value of $50,000 or more. Electrical, mechanical and plumbing projects require a licence when they exceed $10,000. Asbestos, hazardous waste, lead-based paint abatement or removal, and underground storage tank work require a licence at a value of $1 or more, which in practice means always. Under Acts 481 and 757 of 2026 the Board added a fourth low trigger: effective July 1, 2026, water well and environmental well or hole work with a project value of $1 or more requires the appropriate LSLBC licence and classification.

The residential side has its own tiers. A Residential licence is required for residential construction exceeding $50,000, and for home improvement work on existing residential structures exceeding $50,000. Below that, home improvement projects exceeding $7,500 but not in excess of $50,000 require a home improvement registration or a licensed contractor. Residential swimming pool work needs the Residential Swimming Pools classification once labour and materials exceed $7,500, and effective August 1, 2026 residential roofing work with a project value of $7,500 or more requires the Residential Roofing or Residential Construction classification.

• Commercial, major and specialty classifications: $50,000 or more.
• Electrical, mechanical and plumbing: exceeding $10,000.
• Asbestos, hazardous waste, lead-based paint, underground storage tanks: $1 or more.
• Water well and environmental well or hole work: $1 or more, effective July 1, 2026.
• Residential construction and home improvement on existing structures: exceeding $50,000.
• Home improvement registration band: exceeding $7,500 but not in excess of $50,000.
• Residential swimming pools, and residential roofing from August 1, 2026: $7,500 or more.
• Mold remediation: $7,500 or more.

One definition worth reading twice, and one that currently conflicts

"Commercial purpose" is not defined by who pays the invoice. LSLBC defines it as any construction project except residential structures below a stated size. Its Types of Licenses page words that as residential structures with "no more than two incorporated or attached dwelling units". The Board's own licensing brochure words the same definition as "no more than four incorporated or attached dwelling units". Those two official sources do not agree, and the difference decides whether a triplex or fourplex job is screened as commercial or residential. If your work sits in that range, ask the Board directly and get the answer in writing before you bid.

The Board is much clearer on the reverse case. A Commercial licence does not allow you to build a single residential home; that requires a Residential licence with the Residential Construction classification. The only stated crossover runs the other way: a commercial licensee holding the Building Construction classification is exempt from a Home Improvement Registration, and even then the Board caps that at a project value, including labour and materials, that "cannot exceed $50,000".

Build the company in the order Louisiana expects

Decide the legal owner first, because LSLBC will licence that exact name and nothing else. The statute requires a licensee to "bid, contract, conduct all business transactions, and perform work in the name as it appears on the current license or registration and the official records" of the Board, and the Board separately states that it does not recognise DBAs, assumed names or fictitious names. If you plan to trade under a different name, understand before you file that the Secretary of State registers trade names but does not file DBAs at all, which are filed at the parish level with the Clerk of Court.

If the owner will be an LLC, corporation or limited partnership, register it with the Louisiana Secretary of State. geauxBIZ is the state's official portal for creating, maintaining and closing a business, and it also handles trade name and trademark registration, registration with the Department of Revenue and registration with Louisiana Works in the same flow. The published filing fees are $100 for Articles of Organization for a Louisiana LLC, $75 for Articles of Incorporation for a Louisiana business corporation, $25 for a name reservation, and $30 for an LLC or corporation annual report. A name reservation holds the name for 120 days, and every business registration requires an agent with a physical address in Louisiana.

Then handle tax registration. The Louisiana state sales tax rate is 5 percent, and sales tax returns and payments are due on or before the 20th of the month following the close of the reporting month or quarter. Whether you are a "dealer" required to collect and file turns on the definition at R.S. 47:301(4), which the Department of Revenue reproduces on its general sales and use tax page. Read that definition against what you actually sell rather than assuming construction labour is outside it.

Then get the licence, in the order the Board applies it

The licence is not the last step before your first job; it is the step before your first bid. The Board states that "A contractor's license or registration is required before you can bid, contract, or perform work", and that there are no provisions in Louisiana law for a temporary licence. Joint ventures are caught by the same rule: under R.S. 37:2162 a joint venture must be properly licensed at the time of bid, contract and performance, "regardless of whether they intended to operate as a joint venture".

You will need a qualifying party. The Board defines that as a natural person designated to represent the contractor for the purpose of complying with the licensing law, who holds the exam scores and who is not the owner of the licence unless they are a sole proprietor. Eligible qualifying parties include a sole proprietor, a partner named in the partnership agreement, any member or manager of an LLC, any incorporator, stockholder or officer of a corporation, or a full-time employee, which the Board ties to the IRS definition of an employee averaging 30 hours a week or 130 hours a month and receiving a W-2, backed by a notarised affidavit from both employee and employer. There is no limit on how many qualifying parties a company may have.

Commercial and residential applications also require a financial statement showing net worth, current within 12 months of application, plus completion of the Business and Law course and a passing trade exam score where applicable. Mold remediation adds 24 hours of approved training. Home improvement registration requires no trade exam and no financial statement, but does require insurance. Applications are filed through the Board's online application system.

Insurance: the Board's own pages currently disagree, so check both

Read this section carefully, because two official LSLBC sources do not currently say the same thing. The Board's memorandum dated July 13, 2026 states that effective August 1, 2026, "Residential construction, its subclassifications and specialties, mold remediation, and home improvement applicants and licensees must maintain at least $500,000 in liability insurance or qualifying liability protection through an authorized liability trust fund." It cites Act 757 of 2026, La. R.S. 37:2156.1 and LAC 46:XXIX.105. The memorandum also requires that proof come from the agent, broker or insurer, identify the licensee, insurer, broker and broker address, policy number and coverage dates, cover at least six months and all licensed scopes with no exclusions for those scopes, and list LSLBC as certificate holder.

The Board's public FAQ and its "Licensing Requirements for Contractors in Louisiana" brochure both still say "$100,000" as the general liability minimum for home improvement, residential and mold remediation applicants, and both still show the older certificate rules. As of the review date of this guide those pages had not been updated to match the memorandum. Do not resolve that gap by guessing. The memorandum is the newer instrument and states an effective date, so treat $500,000 as the figure to buy toward, and confirm the exact current requirement with LSLBC before your agent issues the certificate. Getting this wrong does not merely cost coverage, it can hold up the licence itself.

Two requirements are not in dispute. Workers' compensation coverage is required with, in the Board's own words, "absolutely no exceptions to the WC requirement", and no minimum coverage amount is specified for it. The certificate must carry the correct name of the company or individual applying, must show effective and expiration dates and limits, must name LSLBC as certificate holder at 600 North Street, Baton Rouge, LA 70802, and must be emailed to the Board by the insurance agent rather than by the contractor. Coverage must stay continuously in effect for as long as the licence or registration is active.

What Louisiana actually publishes about fees

This guide will not print a current LSLBC application fee, because LSLBC does not publish a fee schedule on its website and no official page states one. What does exist is the statutory ceiling. The Contractors Licensing Law, published by the Board itself, provides at R.S. 37:2156(C) that "Fees for licenses shall not exceed the following amounts", then lists an examination fee of $50.00, a licence fee of $100.00, a renewal fee of $100.00, a delinquent fee of $50.00 and a Home Improvement fee of $50.00. R.S. 37:2156(B)(1) separately provides that "the basic license fee shall be the sum of not more than one hundred dollars" and that the fee for additional classifications shall be a lesser amount set by the Board.

Those are caps on what the Board may charge, not a price list, and two other charges sit outside them. The Board may assess an additional surcharge of not more than $400 in connection with the application of a contractor not domiciled in Louisiana, to defray the cost of investigating that application. And R.S. 37:2156(K)(1) requires the Board to assess on each licence renewal an additional fee of $100 per year dedicated to a Louisiana public university or community college school of construction management. The FAQ also confirms that "An exam/administrative fee is required for each classification and for Business and Law", without stating the amount.

Budget from the application itself, not from this page. Open the online application, list every classification you intend to hold, and price the Business and Law course, each trade exam, the licence, and the first renewal separately. Then add the costs that never appear on a Board invoice at all: the financial statement, the insurance certificates, the Secretary of State filings and your parish or municipal occupational licence.

Keep the licence alive and the paperwork in one place

Louisiana licences and renewals expire on the anniversary of the date the licence was originally issued, and licensees elect a one-, two- or three-year renewal term at renewal. A renewal application filed more than fifteen days after the expiration date draws a delinquent fee, capped by statute at $50. Insurance is not a one-time hurdle either: the Board requires current certificates at renewal and requires that coverage remain continuously in effect while the licence or registration is active.

Continuing education applies unevenly, so check your own licence type rather than a general rule. The Board states there are no continuing education requirements for commercial, mold or home improvement contractors and registrants. A residential construction contractor must complete at least six hours of continuing education annually with a board-approved provider, keep the certificate for five years and produce copies on request; that six-hour requirement is treated as met if the residential contractor also holds a valid current commercial licence in one of the four major classifications. Water well contractors licensed under the 2026 changes have their own five-hour annual requirement and must remain in good standing with the Louisiana Department of Conservation and Energy.

Keep one permanent company file: the Secretary of State filing and annual report confirmations, the registered agent record, the Department of Revenue accounts, the LSLBC application and licence with every classification listed on it, the financial statement, the exam and Business and Law completions, each insurance certificate as issued to LSLBC, the parish or municipal occupational licence, and the renewal dates for all of it. Louisiana will not remind you that a classification you never added is the reason a bid is invalid.

Recheck the official source before you file or sign

Louisiana contractor law changed materially in 2026 and the Board's own public pages have not all caught up, which is the strongest possible argument for opening the source yourself rather than trusting any summary, including this one. Act 757 of 2026 added a residential roofing threshold and raised the liability insurance requirement, both effective August 1, 2026, and Acts 481 and 757 brought water well and environmental well or hole work under licensing at a project value of $1 or more effective July 1, 2026.

Before you file an application, sign a contract, or buy an insurance policy, open the Board's current page for your licence type, confirm the threshold, the classification wording, the insurance limit and the certificate rules, and keep a dated copy of what you read. The Board's own memorandum says it "is intended to provide general notice of statutory changes" and that "The applicable statutes and regulations control in the event of any conflict or question of interpretation." Where a page and a statute disagree, the statute wins, and where you cannot tell, call the Board at the number on its contact page before you commit money.
