No state credential was found for routine pool cleaning and water-chemistry service. Building pools is contractor work: MSBOC lists a Swimming Pools specialty, with a trade exam, under the Building Construction, Mechanical, and Municipal and Public Works majors, required for public or private pool contracts of $50,000 or more.
At homes, pool construction or remodeling over $10,000 for an existing residence fits the statutory remodeler definition (Miss. Code Ann. § 73-59-1(c)), and any subcontractor doing the electrical, plumbing, or mechanical work on a residential project needs the matching MSBOC residential license regardless of dollar amount (§ 73-59-3(1)(d)).
The state sets the license floor; the county or city permit office controls filing, inspections, and local rules wherever the job site sits.
Mississippi licensing is statewide through MSBOC, but cities and counties enforce it: building officials must refuse permits to anyone who would be a residential builder or remodeler unless they show an MSBOC license or exemption, and must report suspected violations to the Board (Miss. Code Ann. § 73-59-17). Residential contractors without a permanent Mississippi place of business (and not holding a commercial certificate) also need a Department of Revenue permit under § 27-65-27 to obtain a building permit, regardless of project cost or insurance funding (§ 73-59-18).

Statutory consequences with their citations — not estimates, not “commonly cited” guesses.
Undertaking residential work that requires an MSBOC license without one — or giving the Board false information to get one — is a misdemeanor, and the Board may cite and stop the work.
A contractor unlicensed when the work was performed may not sue to enforce a residential building or remodeling contract; recovery is limited to documented labor and material expenses proved by clear and convincing evidence.
A public or private contract awarded to a contractor without a certificate of responsibility is void; knowingly bidding without one is a misdemeanor, and the Board may order abatement.
Inside city limits, the city office listed here issues the permit; the county office serves unincorporated areas. Every office links to its official page.
