Contractor licensing

Louisiana contractor license requirements

Louisiana licenses contractors statewide through the Louisiana State Licensing Board for Contractors (LSLBC), and the license you need depends on whether the job is commercial or residential and what it is worth, including labor and materials.

Yes, Louisiana requires a state contractor license, and it is one of the stricter states about it. The Louisiana State Licensing Board for Contractors (LSLBC) issues four basic license types: Commercial, Residential, Home Improvement, and Mold Remediation. Which one you need is set by dollar thresholds. A commercial project of $50,000 or more needs a commercial license. Residential construction of $50,000 or more needs a residential license. Home improvement work starting at $7,500 needs at least a home improvement registration. Electrical, mechanical, and plumbing work trips the line at just over $10,000, and hazardous materials work needs a license at $1.

Commercial license: the $50,000 line

The LSLBC says commercial projects with a value of $50,000 or more must be bid or performed by a properly licensed commercial contractor when the property will be used for commercial purposes. The value counts labor and materials together, so a $30,000 labor quote with $25,000 of owner-supplied steel is still a $55,000 job in the board's eyes. The statute (R.S. 37:2150.1) and the board's printed requirements booklet define commercial purposes as any project except residential structures with no more than four dwelling units, while the board's types of licenses page still shows a two-unit cutoff. If you are bidding a triplex or fourplex, call the board before you price it.

The threshold applies down the chain too. Subcontracts of $50,000 or more on commercial work must be performed by a licensed subcontractor. That matters for a general contractor building a bid list: a $70,000 framing package or a $120,000 storefront scope has to go to a licensed sub, and the GC is the one who looks bad if it does not.

  • Electrical, mechanical, and plumbing: a license is required once the project exceeds $10,000, labor and materials included.
  • Hazardous materials: asbestos, hazardous waste, lead-based paint abatement or removal, and underground storage tank work need a license at a project value of $1 or more. There is no small-job exception.
  • Labor-only classifications: the board notes that labor-only commercial classifications do not require a trade exam, though the Business and Law course still applies.

Residential license, home improvement registration, and mold

Residential construction or home improvement projects of $50,000 or more, or any job involving structural work, must be bid and performed by a licensed Residential Building Contractor. A residential licensee can contract for a residential swimming pool but must use a sub holding the Residential Swimming Pools classification unless it holds that classification itself, and pool subs need that specialty once the work exceeds $7,500.

Below the residential line sits the Home Improvement Registration. It covers reconstruction, alteration, renovation, repair, and similar work on an existing home when the project is over $7,500 and not more than $50,000. Say a remodeler signs a $38,000 kitchen and bath job: a home improvement registration covers it. Add a load-bearing wall removal and the structural work pushes it into the residential license, regardless of price.

Mold remediation projects of $7,500 or more need a Mold Remediation license. The qualifying party must complete 24 hours of approved training in mold remediation and basic mold assessment, and the board posts approved training providers on its site.

How to get a Louisiana contractor license

  1. Pick the license type and classifications that match the work you will bid, using the board's types of licenses and classifications pages.
  2. Name a qualifying party. The LSLBC describes the qualifying party as the person who holds the exam scores. It can be a sole proprietor, partner, LLC member or manager, corporate officer, or full-time employee, each with its own supporting documents.
  3. Complete the online Business and Law course, which the board requires of all license applicants.
  4. Pass the trade exam for each classification that needs one. Approved candidates get an eligibility letter from PSI with scheduling details, and an exam or administrative fee applies for each classification and for Business and Law.
  5. Prepare a financial statement current within 12 months showing at least $50,000 net worth for commercial or residential, or $25,000 for mold remediation.
  6. Submit proof of insurance where required: general liability of at least $100,000 for residential and home improvement applicants ($50,000 for mold remediation) and workers' compensation coverage.
  7. File the application through the LSLBC online application portal.

The initial license is good for one year. After that you can renew for one, two, or three years. Renewal opens 60 days before expiration, and the board emails reminders at 60 and 15 days out. If a license stays expired for a year, you have to reapply from scratch. Residential, mold remediation, and home improvement licensees must show current liability and workers' comp coverage at renewal, and residential contractors need six hours of board-approved continuing education every year.

Checking a Louisiana contractor license

The LSLBC contractor search runs in real time against the board's licensing database. You can search by company name, license number, city, parish, contractor type, or qualifying party. The board's free mobile app, La. Contractor, does the same lookup from the job site. Check every sub before the subcontract is signed, and check again before you release a large payment, because a lapsed license or a classification that does not cover the scope is your problem as much as theirs.

Licensing is only one piece of getting paid in Louisiana. Read the Louisiana mechanics lien rules and Louisiana prompt payment and retainage rules before your first big job, and keep a current certificate of insurance on file for every sub. A subcontractor COI tracking template works for a handful of subs. Once you are tracking dozens of licenses, classifications, and insurance expirations, Smart Business Automator's subcontractor compliance automation flags lapses before a sub mobilizes.
