A provision in HB953 shifts plumbing licensing authority and creates new compliance requirements for any business that bids on or performs plumbing work.
Most Louisiana manufacturers don't realize that a plumbing licensing change buried in HB953 could directly affect their ability to bid on or perform plumbing work—and the penalties for non-compliance are steep.
Here's what changed: Starting January 1, 2027, any small business or manufacturer that bids on or performs plumbing work must obtain a plumbing contractor license from the State Licensing Board for Contractors (SLBC), rather than from the State Plumbing Board as before. This shift consolidates plumbing contractor oversight under a different state agency.
If your manufacturing operation includes in-house plumbing work, bids on projects with plumbing components, or subcontracts plumbing services, this applies to you. It also affects any contractor or vendor your company hires to do plumbing work on your behalf.
Operating without the correct license is now an enumerated violation under Louisiana law. The consequences include:
These aren't minor administrative slaps. A 10% fine on a six-figure plumbing contract can be substantial, and debarment can lock you out of bidding on public or regulated projects for years.
The effective date for the main licensing requirement is January 1, 2027 (Sections 1–5 of HB953). Before that date, both the SLBC and the State Plumbing Board must complete rulemaking to establish how the new licensing process will work, what qualifications are required, and how applications will be processed. Section 6 of the bill requires these preparatory actions.
This means the rules governing the new license aren't finalized yet. Manufacturers should monitor announcements from the SLBC starting in 2026 for application procedures, fees, and documentation requirements.
Review your current plumbing work practices and vendor relationships. If you perform plumbing work in-house or regularly bid on projects with plumbing components, plan to apply for the SLBC plumbing contractor license well before the January 1, 2027 deadline. If you use subcontractors for plumbing, verify they will obtain the correct license and build compliance timelines into your vendor management process.
