Louisiana Contractor Licenses: Updated Requirements Guide

Overview of Louisiana Contractor Licensing

Louisiana regulates contractors through multiple authorities. The Louisiana State Licensing Board for Contractors (LSLBC) oversees commercial and residential contracting across major classifications, including Building Construction, Residential Building, Residential Renovation, Highway/Street/Bridge, Heavy Construction, Home Improvement, and certain specialty activities such as mold remediation. Thresholds commonly encountered include $50,000 for commercial projects and $75,000 for residential construction, with home improvement projects regulated between $7,500 and $75,000. Commercial electrical, mechanical, and plumbing scopes often trigger state licensing requirements at $10,000 and above.

Plumbing contracting is separately regulated at the state level by the Louisiana State Plumbing Board. In addition, some cities—most notably the City of New Orleans—maintain their own local licensing for electrical and mechanical (HVAC) contractors within city limits. This guide presents the state-level licenses first, followed by per-trade sections that highlight local licenses where applicable.

Because Louisiana blends state and local oversight, you may need to hold both a state contractor license and a city-issued credential to lawfully perform work. Always align your licensing plan with where you will perform work and the value/scope of your projects.

State-Level Licenses in Louisiana

State-level licensing in Louisiana refers to licenses and registrations issued by a statewide authority and valid across Louisiana, subject to any local business licensing or permitting. The LSLBC regulates most general and residential contracting, home improvement work between set thresholds, and selected specialties. The Louisiana State Plumbing Board regulates plumbing contracting statewide.

Below are the principal state-level credentials by trade. For local credentials (for example, New Orleans electrical and mechanical), see the per-trade sections that follow.

State-Level Electrician Licenses

Louisiana does not issue a statewide electrician contractor license in the materials provided here. If your scope includes electrical work within commercial projects, note that state thresholds may apply at $10,000 and above. Local jurisdictions may also have their own electrical licensing—see the Electrician section below.

State-Level HVAC Licenses

HVAC/mechanical contracting is not shown here as a standalone statewide license; however, commercial mechanical scopes commonly trigger state-level requirements at $10,000 and above. New Orleans also licenses mechanical contractors locally—see the HVAC section below.
