Louisiana Plumbing Contractor License — Act 908 and the LSLBC Transfer

Louisiana's plumbing licensing landscape is in the middle of a major structural change. Act 908 (House Bill 953), passed during the 2026 Regular Legislative Session, abolished the independent State Plumbing Board of Louisiana and transferred all regulatory authority to the LSLBC, effective January 1, 2027.

What Act 908 Changes

Before Act 908, plumbing contractors answered to two separate boards: the State Plumbing Board of Louisiana (SPBLA) handled individual plumber licensing and trade testing, while the LSLBC handled contractor-level business licensing when plumbing projects exceeded $10,000.

Act 908 consolidates everything under the LSLBC. Specifically:

New Plumbing Contractors Subcommittee. Act 908 establishes a dedicated Plumbing Contractors Subcommittee within the LSLBC to handle regulatory, testing, and licensing matters for the plumbing trade after the January 1, 2027 transfer.

Reduced experience requirements. Under Act 908's new rule, individual journeyman plumbing experience requirements will be reduced from 7,000-8,000 hours to 2,500 verified hours. This is a significant reduction that opens the trade to a wider pool of candidates.

New license distinction. Act 908 created a formal separation between an individual plumber's license (for employees who perform plumbing work) and a plumbing contractor's license (for business entities that contract directly with clients). Previously, this distinction was blurry and caused confusion about when a plumber needed contractor-level licensing versus just an individual trade credential.

The $10,000 Licensing Trigger

The monetary threshold for plumbing contractor licensing remains unchanged at $10,000. Any plumbing project where the contract value — including all labor and materials — exceeds $10,000 requires the contractor to hold an LSLBC plumbing specialty license.

This threshold applies to both commercial and residential projects. A residential bathroom renovation that includes extensive plumbing work can easily cross the $10,000 line once supply rough-in, fixture installation, and water heater connections are factored in.

Licensing Path After the Transfer

After the January 1, 2027 transfer, the licensing pathway for plumbing contractors will run through the LSLBC:

1. Form your business entity and register through GeauxBiz
2. Prepare a CPA financial statement demonstrating $50,000 minimum net worth
3. Submit your LSLBC application selecting the plumbing specialty classification
4. Designate a qualifying party with verified plumbing experience (2,500 hours minimum under Act 908's new rule)
5. Complete the Business & Law course through the LSLBC portal
6. Pass the plumbing trade exam administered by PSI Services
7. File insurance certificates — commercial plumbing contractors are exempt from filing GL directly with the LSLBC but must maintain coverage for local permit requirements; residential-scope plumbing contractors must file $500,000 GL and workers' comp

Transition Timeline

The formal transfer takes effect January 1, 2027, but the transition has practical implications for existing license holders:

• Active SPBLA licenses — follow the SPBLA/LSLBC transition instructions and verify your status as the January 1, 2027 transfer approaches.
• Pending SPBLA applications — check the transition instructions for how applications will be handled after January 1, 2027.
• Testing transitions — after the transfer, PSI Services will administer plumbing trade exams on behalf of the LSLBC; check the current testing instructions during the transition.

The SPBLA website remains a transition resource; use it alongside the LSLBC site for current information.

Why This Matters for General Contractors

If you hold a general contractor license and subcontract plumbing work, you need to verify that your plumbing subs are properly licensed under the new LSLBC framework. Contracting with an unlicensed plumbing subcontractor is a violation that can result in disciplinary action against your own license.

The Louisiana General Contractor License Guide covers the plumbing specialty classification alongside all other LSLBC license types, with the updated Act 908 requirements built into the application workflow.
