Louisiana State Licensing Board for Contractors, 600 North Street, Baton Rouge, LA (2026)

10/07/2026

🔧 Here’s another important update for Louisiana’s plumbing professionals.

Right now, the plumbing contractor licensing requirement generally starts when the plumbing project reaches $10,000.

Beginning January 1, 2027, that $10,000 threshold goes away.

That means the cost of the job will no longer be what determines whether a plumbing contractor license is required. A plumbing job won’t have to reach $10,000 before the licensing requirements may apply.

We know there are a lot of questions about the new plumbing requirements, and we’ll keep sharing information between now and January 1 to help everyone know what to expect.

If your company already holds an active LSLBC contractor license with the Plumbing classification, here’s an important part of the January 1 transition:

𝐘𝐨𝐮 𝐚𝐫𝐞 𝐧𝐨𝐭 𝐬𝐭𝐚𝐫𝐭𝐢𝐧𝐠 𝐨𝐯𝐞𝐫.

Existing LSLBC Plumbing classifications will automatically transition to the new Master Plumbing Contractor classification on January 1.

Why?

LSLBC’s current Plumbing classification already requires the qualifying credential of a Master Plumber license issued by the State Plumbing Board of Louisiana.

Under the new law, a licensed Master Plumber is the qualifying party for a Master Plumbing Contractor, which may contract to perform plumbing work on any structure.

As Louisiana transitions plumbing licensing to the Louisiana State Licensing Board for Contractors (LSLBC), one of the most important things for plumbers, contractors and local permit offices to understand is the difference between an individual plumber license and a plumbing contractor license.

Beginning January 1, there will be two plumbing contractor licenses:

🏢 𝐌𝐚𝐬𝐭𝐞𝐫 𝐏𝐥𝐮𝐦𝐛𝐢𝐧𝐠 𝐂𝐨𝐧𝐭𝐫𝐚𝐜𝐭𝐨𝐫

A Master Plumbing Contractor may contract to perform plumbing work on 𝐚𝐧𝐲 𝐬𝐭𝐫𝐮𝐜𝐭𝐮𝐫𝐞.

The qualifying party for this license must be a licensed Master Plumber and meet the other requirements for contractor licensure.

🏠 𝐑𝐞𝐬𝐢𝐝𝐞𝐧𝐭𝐢𝐚𝐥 𝐏𝐥𝐮𝐦𝐛𝐢𝐧𝐠 𝐂𝐨𝐧𝐭𝐫𝐚𝐜𝐭𝐨𝐫

A Residential Plumbing Contractor may contract to perform plumbing work on 𝐫𝐞𝐬𝐢𝐝𝐞𝐧𝐭𝐢𝐚𝐥 𝐬𝐭𝐫𝐮𝐜𝐭𝐮𝐫𝐞𝐬 𝐧𝐨𝐭 𝐦𝐨𝐫𝐞 𝐭𝐡𝐚𝐧 𝐭𝐡𝐫𝐞𝐞 𝐟𝐥𝐨𝐨𝐫𝐬 𝐢𝐧 𝐡𝐞𝐢𝐠𝐡𝐭.

This license may be qualified by either a licensed Journeyman Plumber or licensed Master Plumber, along with meeting the other requirements for contractor licensure.

𝐖𝐡𝐲 𝐝𝐨𝐞𝐬 𝐭𝐡𝐢𝐬 𝐦𝐚𝐭𝐭𝐞𝐫 𝐚𝐭 𝐭𝐡𝐞 𝐩𝐞𝐫𝐦𝐢𝐭 𝐨𝐟𝐟𝐢𝐜𝐞?

Louisiana law requires a person obtaining a building permit for work that requires a contractor’s license to hold an active contractor’s license in the appropriate classification for the scope of work.

In other words, holding an individual Journeyman Plumber or Master Plumber license does not, by itself, mean you hold a plumbing contractor license.

The individual license establishes the plumber’s qualification. The appropriate contractor license is what authorizes the business to contract for the plumbing work within the scope allowed by that license.

Individual 𝐀𝐩𝐩𝐫𝐞𝐧𝐭𝐢𝐜𝐞, 𝐉𝐨𝐮𝐫𝐧𝐞𝐲𝐦𝐚𝐧 𝐚𝐧𝐝 𝐌𝐚𝐬𝐭𝐞𝐫 𝐏𝐥𝐮𝐦𝐛𝐞𝐫 𝐥𝐢𝐜𝐞𝐧𝐬𝐞𝐬 will also be administered by LSLBC beginning January 1.

These changes are part of Louisiana’s 2026 legislation transferring plumbing regulation to LSLBC. We will continue sharing information in the coming months to help plumbers, contractors, permit offices and the public prepare for the transition.

Statutory exemptions from contractor licensure continue to apply where provided by Louisiana law.

It may be more than the amount on one contractor’s invoice.

Under Louisiana contractor licensing law, project value includes the entire cost of:

• Labor
• Materials
• Rentals
• Direct and indirect project expenses

And here’s the part many people may not realize:

𝗠𝗮𝘁𝗲𝗿𝗶𝗮𝗹𝘀 𝗮𝗻𝗱 𝗽𝗿𝗼𝗷𝗲𝗰𝘁 𝗲𝘅𝗽𝗲𝗻𝘀𝗲𝘀 𝗰𝗮𝗻 𝗰𝗼𝘂𝗻𝘁 𝗲𝘃𝗲𝗻 𝘄𝗵𝗲𝗻 𝘁𝗵𝗲 𝗽𝗿𝗼𝗽𝗲𝗿𝘁𝘆 𝗼𝘄𝗻𝗲𝗿 𝗯𝘂𝘆𝘀 𝘁𝗵𝗲𝗺 𝗱𝗶𝗿𝗲𝗰𝘁𝗹𝘆—𝗼𝗿 𝘄𝗵𝗲𝗻 𝘁𝗵𝗲𝘆 𝗮𝗿𝗲 𝗱𝗼𝗻𝗮𝘁𝗲𝗱.

Another important term is scope of work.

Licensing requirements are not determined simply by looking at what one person was paid. You have to look at the work that was agreed to and the value of that scope of work.

For example, if more than one contractor is involved in performing the same scope of work, you cannot necessarily separate the project into each contractor’s individual invoice when determining licensing requirements. The value of the whole scope of work may matter.

Likewise, if an owner purchases the materials and hires someone only for labor, the project value is not necessarily just the labor charge.

Why does this matter?

Because Louisiana contractor licensing and registration requirements are based in part on the value of the project or scope of work, not simply the amount paid directly to one person performing the work.

Louisiana is building — and the scale of construction activity happening across our state is significant.

Major industrial investments, infrastructure projects, new facilities, and expanding communities are creating construction activity that reaches far beyond the boundaries of any one project. With that growth comes opportunity for contractors and subcontractors at every level.

Over the coming weeks, LSLBC will take a closer look at Louisiana’s construction boom — where major projects are taking shape, what that growth means for the construction industry, and why proper licensing and classifications matter as the work expands.

Big projects create big opportunities. Let’s make sure Louisiana is ready to build them well.

This is what investing in the future of Louisiana’s construction industry looks like.

Construction Education Trust Fund dollars are reaching beyond universities and into career and technical education programs, giving younger students opportunities to discover construction careers, develop real skills, and see a future for themselves in the industry.

The answer may depend on where the project is located and what kind of work is being done.

Building permits are generally handled by your local parish or municipal permit office, and procedures can vary from one jurisdiction to another.

Before work begins, homeowners and contractors should confirm:

• Whether a permit is required
• Who may apply for the permit
• What inspections will be required
• What contractor license or classification is required for the work

But one thing does not change:

𝐀 𝐩𝐞𝐫𝐦𝐢𝐭 𝐝𝐨𝐞𝐬 𝐧𝐨𝐭 𝐭𝐚𝐤𝐞 𝐭𝐡𝐞 𝐩𝐥𝐚𝐜𝐞 𝐨𝐟 𝐚 𝐫𝐞𝐪𝐮𝐢𝐫𝐞𝐝 𝐜𝐨𝐧𝐭𝐫𝐚𝐜𝐭𝐨𝐫’𝐬 𝐥𝐢𝐜𝐞𝐧𝐬𝐞.

Louisiana law generally prohibits a local building department from issuing a permit to someone who does not hold the active contractor’s license and appropriate classification required for the work. Work that does not require a state contractor’s license is treated differently.

⚠️ 𝐇𝐎𝐌𝐄𝐎𝐖𝐍𝐄𝐑𝐒: 𝐁𝐄 𝐂𝐀𝐑𝐄𝐅𝐔𝐋 𝐖𝐇𝐄𝐍 𝐔𝐒𝐈𝐍𝐆 𝐓𝐇𝐄 𝐇𝐎𝐌𝐄𝐎𝐖𝐍𝐄𝐑 𝐄𝐗𝐄𝐌𝐏𝐓𝐈𝐎𝐍.

Louisiana law allows a qualifying homeowner to obtain a permit for work on the homeowner’s primary residence by signing the LSLBC Affidavit Claiming Exemption from Licensure.

But signing that affidavit does more than allow you to pull the permit.

𝐘𝐨𝐮 𝐚𝐫𝐞 𝐚𝐜𝐭𝐢𝐧𝐠 𝐚𝐬 𝐭𝐡𝐞 𝐠𝐞𝐧𝐞𝐫𝐚𝐥 𝐜𝐨𝐧𝐭𝐫𝐚𝐜𝐭𝐨𝐫 𝐚𝐧𝐝 𝐛𝐞𝐜𝐨𝐦𝐞 𝐭𝐡𝐞 𝐜𝐨𝐧𝐭𝐫𝐚𝐜𝐭𝐨𝐫 𝐨𝐟 𝐫𝐞𝐜𝐨𝐫𝐝 𝐟𝐨𝐫 𝐭𝐡𝐞 𝐩𝐫𝐨𝐣𝐞𝐜𝐭.
That means you assume legal and financial responsibility for the entire project, must provide direct onsite supervision, and are responsible for making sure the work complies with applicable laws, ordinances, building codes and zoning requirements.

The homeowner exemption also does not allow you to hire an unlicensed person to act as your contractor or construction manager, and it does not eliminate licensing requirements that apply to subcontractors.

If you are hiring a contractor to run the project, the safer course is to make sure that contractor is properly licensed and that the permit accurately reflects who is actually acting as the contractor.

✅ Check with your local permit office.
✅ Verify the contractor’s license and classification with LSLBC.
✅ Make sure the permit accurately identifies who is responsible for the work.

If you have a concern involving a contractor or construction project, providing clear information at the beginning helps LSLBC understand what happened and identify the person or company involved.

When filing your complaint, be prepared to tell us:

• Who you hired or agreed with to perform the work
• The person and/or company name you dealt with
• What name appears on your contract, proposal, estimate, invoice or receipt
• Who you paid or made payments payable to
• The address and type of project
• The approximate contract or project amount
• When the work began
• A brief explanation of what happened
• Whether law enforcement or an insurance company is involved, if applicable

If you have them, keep your contract, proposal, estimates, invoices, receipts, proof of payment and relevant communications available. These documents can help identify the responsible parties and assist with review of the complaint.

Not sure whether the individual, the company, or both should be named in your complaint? That’s okay. Give us the information you have about who you dealt with, who was paid and whose name appears on your paperwork.

You do not need to know a contractor’s license number before filing a complaint.

And you do not need to have every piece of information before contacting LSLBC. Do not delay filing simply because something is missing.

The more clearly we understand who was involved, what work was agreed to, what happened and how much the project involved, the better we can determine the appropriate next step.

Hiring a contractor? Take two minutes to check a few things before money changes hands.

𝟏. 𝐒𝐞𝐚𝐫𝐜𝐡 𝐭𝐡𝐞 𝐜𝐨𝐧𝐭𝐫𝐚𝐜𝐭𝐨𝐫.
Look up the contractor or business through LSLBC and confirm that the credential is current.

𝟐. 𝐂𝐡𝐞𝐜𝐤 𝐭𝐡𝐞 𝐜𝐥𝐚𝐬𝐬𝐢𝐟𝐢𝐜𝐚𝐭𝐢𝐨𝐧.
A contractor may be licensed, but that does not necessarily mean the license covers the work you are hiring them to perform. Check the classifications listed on the license.

𝟑. 𝐂𝐡𝐞𝐜𝐤 𝐭𝐡𝐞 𝐧𝐚𝐦𝐞 𝐨𝐧 𝐲𝐨𝐮𝐫 𝐜𝐨𝐧𝐭𝐫𝐚𝐜𝐭.
The business you are contracting with should match the business you verified. Be cautious if you are given a license number belonging to someone else or told that a person or business is “working under” another contractor’s license.

A quick check before signing a contract or paying a deposit can help prevent problems later.

Not sure what credential or classification is required for your project? Contact LSLBC. We’re happy to help you figure it out.
