Open the Mississippi State Board of Contractors’ classification listing, search it for the pool specialty, and you will find it three times.
That is not duplication. It is how the board tells you which broader licenses already contain pool work — and it is the first thing a Mississippi pool company should understand about its own market.
Majors, specialties, and what a major carries with it
The board sets out the architecture before the lists start. Two sentences do most of the work:
Holding a major classification entitles the license holder to perform all of the specialty classifications noted within the major classification category. Applicants who do not desire a major classification may choose an unlimited number of specialty classifications.
So there are two routes. Hold a major and you inherit every specialty nested beneath it. Or hold no major and assemble specialties instead — with no cap on how many.
The second route is priced per item: “One selection is included with the application fee, but each additional selection requires an additional $100 fee,” and the board notes that fees are non-refundable. Treat that figure as the one on the listing you read rather than the one here.
The pool specialty, in full
SWIMMING POOLS (Test Required). A specialty classification that involves the construction, repair, and servicing of any swimming pool, hot tub or spa, except for solar pool heating, whether public, private or otherwise, regardless of use. The scope of work includes the installation, repair, or replacement of existing equipment, any cleaning or equipment sanitizing which requires at least a partial disassembling and the installation of new pool/spa equipment, interior finishes, the installation of package pool heaters, the installation of all perimeter piping and filter piping. The scope of work does not include direct connections to a sanitary sewer system or to potable water lines, or electrical work.
The “(Test Required)” marker is the board’s own, and it is not on every classification in the list — some carry it, some do not. Pool work does.
Note also “whether public, private or otherwise, regardless of use.” The classification is not split by ownership or by who swims in the pool. A municipal facility, a hotel amenity and a backyard build sit inside the same specialty.
Solar heating is carved out by name
The exclusion sits inside the opening sentence rather than at the end: construction, repair and servicing of any pool, hot tub or spa “except for solar pool heating.”
Read that against the next clause and the line becomes precise. The scope expressly includes “the installation of package pool heaters.” So heating is not the problem — solar is. A Mississippi pool contractor can install a packaged heater under this specialty and cannot install solar heating under it.
It is worth noticing how differently states treat the same technology. Arizona builds solar into its pool licensing as a parallel classification you can hold — A-19, B-6 and KA-6 exist precisely so a pool contractor can add solar heating to its own scope. Mississippi takes the opposite approach and lifts solar out of the pool specialty altogether. Two confirmed states, the same equipment, opposite drafting choices.
Where solar pool heating does sit in Mississippi is not something this post asserts. The pool specialty tells you it is elsewhere; it does not tell you where.
The cleaning line is drawn at disassembly
One clause in the scope is doing quiet work for service companies:
any cleaning or equipment sanitizing which requires at least a partial disassembling
The test is mechanical, not commercial. It does not ask whether you are paid, whether the account is recurring, or how large the job is. It asks whether the equipment has to come apart.
That places routine chemical treatment and surface maintenance outside the licensed scope, and equipment service that requires opening something up inside it. A route technician and a repair technician can be doing work on opposite sides of that line on the same afternoon at the same pool.
Where the scope stops
The closing sentence names three exclusions in one breath:
The scope of work does not include direct connections to a sanitary sewer system or to potable water lines, or electrical work.
The first two are familiar boundaries — the utility tie-ins sit outside the pool trade in several states. The third is the one to plan around.
“Or electrical work” is unqualified. It is not limited by voltage. It does not stop at a disconnect. It does not carve out bonding, or lighting, or the equipment pad. As written, electrical work is simply not in this specialty, which makes the exclusion broader than the versions that name a stopping point on a circuit.
For a builder that means an electrical credential is on essentially every job, held by someone else. For a service company it means the same thing on any call that touches wiring rather than water.
Three majors already contain the pool specialty
Here is where the repeated listing pays off. Swimming Pools appears as a specialty beneath:
- Building Construction
- Mechanical
- Municipal and Public Works
Combined with the board’s rule that a major carries all the specialties listed beneath it, that means three separate major classifications reach pool work without their holders ever applying for the pool specialty.
For a Mississippi pool company this is competitive information rather than compliance information. The field licensed to bid your work is wider than the set of Swimming Pools specialty holders — it includes commercial builders, mechanical contractors and public-works contractors who hold the majors. Holding the specialty says what you do. It does not reserve the work.
It also suggests something about where pool work sits in the board’s mental model: alongside building, alongside mechanical, and alongside municipal infrastructure, rather than in one obvious home.
The bond, without a number
Mississippi’s licensing carries financial requirements, and this post does not publish bond amounts. They move, they differ by what is being satisfied, and a figure taken from an article is the wrong thing to plan an application around.
What is stable is the difference between the two instruments a contractor carries. A bond answers to the state and to the people your work affects; it does not defend you, and it expects repayment for whatever it pays out. A liability policy answers to you. Carrying one says nothing about the adequacy of the other.
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.
An unqualified electrical exclusion changes the paperwork
The insurance consequence here follows straight from the scope language rather than from anything added to it.
When electrical work is entirely outside your classification, every pool you build has a separately licensed electrician inside it — on your excavation, on your schedule, usually under your prime contract. The bonding grid, the lighting, the equipment pad wiring and the controls are all somebody else’s licensed scope and your commercial responsibility.
That arrangement moves the risk onto documents rather than onto craftsmanship. Whether the electrician’s certificate was current on the day. Whether the additional-insured wording matches what your customer required of you. Whether the indemnity you accepted upstream is the one you passed downstream. Those are the questions a claim asks, and none of them is visible while the job is going well.
We look at that alongside the coverage itself — our Mississippi pool contractor insurance page explains the approach, and a quote request gets the subcontracted electrical scope reviewed with the rest of the program.
Check the board’s current listing
Every quotation above comes from the Mississippi State Board of Contractors’ own classification listing, and the link goes to it. Classification lists are revised, fees change, and the scope wording of a specialty can be amended without announcement. Confirm the current position with the Mississippi State Board of Contractors before you file — the fees, the examination requirements, the financial and bonding requirements, and where solar pool heating sits, none of which we have asserted here. Requirements differ substantially between states; if you work across state lines, begin from the relevant state page rather than assuming Mississippi’s major-and-specialty structure carries over.
