Ask “what license do I need to build a pool in Louisiana” and the honest first answer is another question: for whom, and where.
The state runs the trade through two different subclassifications hanging off two different major classifications. They have different scopes, different codes, different trade examinations and different thresholds. A company that does both commercial and residential work is looking at two licensing conversations, not one.
Then a board rule decides who may lawfully touch a residential pool, and it does not simply say “the pool licensee.”
Four words the board uses precisely
Before the classifications make sense, the vocabulary has to. The Louisiana State Licensing Board for Contractors publishes its own definitions, and they are more disciplined than the words suggest:
- A major classification “allows you to bid or perform work, with some exceptions, on any of the subclassification/specialty type work listed under the respective major classification and/or any other work that might not be listed which is directly related to the major classification.”
- A subclassification is “a division under a major classification for which a contractor may be licensed for a specific trade.”
- A specialty classification is “a classification which does not fall under a major classification in the Louisiana Contractors Licensing Law.”
- A credential is “a classification that requires a certification or license from an outside agency or organization, and/or other documents.”
Pool work never appears as a specialty. It appears twice as a subclassification, under two different parents — which is why the parent you hold matters as much as the pool code you add to it.
1.13 — Swimming Pools, under Building Construction
The commercial entry reads:
Swimming Pools: the construction, installation, maintenance, or repair of all types of in ground swimming pools, whirlpools, water features and fountains and all associated components. Swimming Pools is a subclassification of Building Construction.
Three things are doing work in that sentence.
“In ground.” The commercial subclassification is written for in-ground construction. It is not a general grant over anything holding water on a commercial site.
“Water features and fountains.” Ornamental water is inside the same code as swimming. A company building a hotel water feature and a company building the hotel’s pool are in the same subclassification.
Building Construction is the parent. The major classification above it covers “the building, maintenance, repair, raising, leveling, development, or demolition of any and all structures as well as the landscaping, earthwork, parking areas, driveways, sidewalks, etc.” The pool code is a division of that, and it is examined separately — the board marks it “Trade Exam.”
9.1 — Residential Swimming Pools, under Residential Construction
The residential entry is a different scope, not a smaller version of the same one:
Residential Swimming Pools: the construction, installation, maintenance, or repair of swimming pools, whirlpools, hot tubs, and all related accessories for residential structures. A license is required when the value exceeds $7,500. Residential Swimming Pools is a subclassification of Residential Construction.
Compare it against 1.13 line by line and the differences are deliberate. Hot tubs appear here and not there. Water features and fountains appear there and not here. The residential code is not limited to in-ground work, and it is bounded instead by the phrase “for residential structures.” And it carries its own stated threshold, which the commercial entry does not.
That threshold is low. Seven thousand five hundred dollars is a renovation, a re-plaster, an equipment pad rebuild — not a new build. Residential pool work in Louisiana becomes licensed activity at a much smaller number than most construction does.
The rule that decides who may touch a residential pool
This is the provision to know, and it is a rule rather than a classification description. Section 503 of the board’s rules, reproduced in the board’s own rules and regulations book, reads:
A. Only contractors holding one or more of the license classifications of building construction, swimming pools, or residential swimming pools are permitted to build or repair residential swimming pools when the value of the project exceeds $7500.
Read the list. It names three qualifying classifications, and one of them is the major classification Building Construction — not a pool code at all. Another is the commercial pool subclassification 1.13. A commercially licensed pool builder is qualified to build residential pools in Louisiana without adding 9.1.
What is not on the list is Residential Construction. Which brings us to subsection B.
The residential builder may sell the job and must hand it over
B. Licensed residential construction contractors may bid or sign contracts to build, renovate, or repair residential swimming pools but must contract with a contractor holding a license to build, renovate, or repair the swimming pool if the licensed residential contractor does not hold a license for the classifications authorized to build, renovate, or repair residential swimming pools.
Subsection C adds that a violation may draw disciplinary action from the board.
This is an unusual arrangement and it produces a specific commercial shape. A Louisiana home builder can put a pool in the contract, price it, and carry the customer relationship — and then is required by rule to bring in a qualifying licensee to perform it. The builder stays on the contract; the pool company does the work.
If you are the pool company, that means a meaningful share of your Louisiana work may arrive as subcontracted scope under a builder’s prime contract rather than as your own direct sale. It is worth knowing which side of that rule your book of work actually sits on, because the indemnity language, the certificate requirements and the payment chain all look different from a direct residential job.
The plaster is somebody else’s subclassification
One more division that catches renovation companies. The board’s list includes:
Lathing, Plastering, and Stuccoing: the installation, maintenance, or repair of all plastering or stucco including interior and exterior walls, swimming pools, etc. Lathing, Plastering, and Stuccoing is a subclassification of Building Construction.
Pools are named inside a plastering subclassification that has nothing else to do with pools, and it carries its own trade examination. The board has drawn the line by trade skill rather than by the object being worked on — which is the same logic that put fountains in with pools, applied in the other direction.
Where the board’s own book disagrees with itself
We are not going to give you a single figure for the Residential Construction threshold, and it is worth explaining why rather than quietly leaving it out.
The board’s rules book carries both the Contractors Licensing Law and the board’s rules. Inside that one document, the statutory definition of “contractor” at R.S. 37:2150.1 states a project value of “fifty thousand dollars or more” for a new residential structure and “seven thousand five hundred dollars or more” for improvements or repairs to an existing one. The classification list in the same book describes Residential Construction as applying “when the cost of the undertaking exceeds $75,000.”
The board’s website gives a third presentation again, describing a residential license as required for residential construction exceeding fifty thousand dollars.
There is a plausible reading in which these address slightly different questions — when a person is a contractor at all, versus what a particular classification covers — and the paragraph numbering the rules cite does not match the numbering in the statute text published by the legislature, which is consistent with the renumbering done by the 2026 act that amended this chapter. But “plausible reading” is not the standard for a number on a page someone might rely on.
So: confirm the current residential threshold with the board directly. The pool answer does not depend on it. Every source we fetched agrees that residential pool work above seven thousand five hundred dollars requires one of the three classifications named in Section 503.
Six hours a year, and an exemption worth knowing
Section 505 of the board’s rules requires a residential construction contractor to complete “a minimum of six hours of continuing education annually by a board approved provider,” to keep evidence of it for five years, and to produce that documentation to the board on request. Failure may subject the license to suspension or revocation.
The exemption is the part operators miss. A contractor who holds a residential construction license and a valid current commercial license in building construction; highway, street and bridge construction; heavy construction; or municipal and public works construction “shall be exempt from this continuing education requirement.”
For a pool company already carrying Building Construction with 1.13 on it, adding residential work does not necessarily add an annual education obligation.
Louisiana disciplines you for the bond you failed to produce
Louisiana’s treatment of surety in this chapter is not a licensing bond at all. It is an enforcement rule about the bonds and certificates a project requires.
Section 705 of the board’s rules provides that any person required to be licensed who bids a project requiring a bid bond, the posting of a bond for the project, or certificates of insurance evidencing mandated coverage, and “fails to provide such valid bonds or coverage when due,” is in violation of the Act and the rules. Subsection B extends it past award: once awarded, the licensee “shall not cancel, or otherwise fail to maintain the required insurance coverage or bonding as required in the bid proposal.” Subsection C exposes a violator to suspension, revocation, fines and administrative costs.
That is a rare linkage, and it is worth sitting with. In Louisiana, letting a bond lapse or a certificate expire mid-project is not only a contract problem with the owner. It is a licensing problem with the board.
The practical consequence is that your surety capacity and your certificate discipline are part of your license compliance here. Surety is handled by our sister brand, Wexford Bonds, the Wexford Insurance surety operation, which writes contractor license and permit, bid, and performance and payment bonds.
The classification does not answer the loss
Holding 1.13 or 9.1 tells the board you passed a trade examination. It does not decide who pays when a shell floats during a Gulf Coast rain event, when a subcontracted plasterer’s work fails and the customer’s contract is with the home builder rather than with you, or when the certificate you supplied to a prime contractor turns out not to match the scope you actually performed.
The Section 503 subcontracting structure makes that last one a live Louisiana question rather than a theoretical one. When the rule routes work to you through someone else’s prime contract, the additional insured language, the indemnity you agreed to, and the coverage sitting behind both are what decide the outcome — and none of that is visible on your license.

Verify with the board
Every quotation above is from the board’s classification list, its rules and regulations book, or the Contractors Licensing Law those documents reproduce, and each is linked. This chapter was amended in 2026 and the board’s published materials are not fully aligned on every figure, which is exactly why the section above declines to pick one. Confirm the current position with the Louisiana State Licensing Board for Contractors before you file — the residential threshold, the fees, and the current examination requirements in particular, none of which we have asserted here.
