Mississippi contractor license requirements
Mississippi licenses contractors through the Mississippi State Board of Contractors (MSBOC). Commercial work needs a Certificate of Responsibility at $50,000, residential builders need a license above $50,000, and remodelers need one above $10,000.
Yes, Mississippi has a statewide contractor license, and it comes in two tracks. The Mississippi State Board of Contractors (MSBOC) issues a commercial Certificate of Responsibility for commercial jobs of $50,000 or more, and a residential license for builders on jobs over $50,000 and remodelers on jobs over $10,000. Residential electrical, plumbing, mechanical, and HVAC contractors need a license no matter the dollar amount. Everyone takes a Mississippi Law and Business Management exam.

Who needs a Mississippi contractor license
The commercial law (Miss. Code Title 31, Chapter 3) exempts work that is less than $50,000. So a $50,000 commercial job is covered, not exempt. The definition of contractor reaches subcontractors and sub-subcontractors of any tier, which matters for a general contractor building a sub list. Fire protection work has lower triggers: a certificate is needed at $5,000 or more on public projects and $10,000 or more on private projects.
The residential law (Title 73, Chapter 59) splits builders from remodelers. A residential builder needs a license when the total cost of the undertaking exceeds $50,000. A remodeler needs one when improvements exceed $10,000, and MSBOC applies that same $10,000 line to remodeling, additions, and roofing. Construction managers and residential solar contractors also need a license. A residential builder can take a commercial job only when the contract job does not exceed 7,500 square feet.
Picture a roofing crew in Hattiesburg quoting a $14,500 tear-off and reroof on a house. That job is over $10,000, so the company needs a residential roofing or remodeler license before it signs. Drop the scope to an $8,000 repair and the state license is not triggered, though local permit rules still apply.
Classifications and exams
Commercial licenses are issued by classification. The major classifications are Building Construction, Electrical, Highway Street and Bridge Construction, Heavy Construction, Mechanical, and Municipal and Public Works. There is a long list of specialty classifications too, some tested (Plumbing; Roofing, Sheet Metal and Siding) and some not. Residential classifications include Builder, Construction Manager, Electrical, HVAC, Mechanical, Plumbing, Remodeler, Roofer, and Solar, and MSBOC lists each as test required.
- Business exam: every applicant takes the Mississippi Law and Business Management exam.
- Trade exam: required for major classifications and tested specialties.
- Provider: PSI administers all exams, and they are open book.
- NASCLA: a passing score on the NASCLA Accredited Examination for Commercial General Building can stand in for the Mississippi Building Construction trade exam.
Financial statement, insurance, and fees
Commercial applicants submit a CPA-reviewed financial statement showing net worth of $50,000 or more for a major classification, or $20,000 for a specialty. Renewals need a balance sheet prepared under generally accepted accounting principles. If your books are not already in shape, the same statements a surety asks for will help here; see construction financial statements bonding companies want.
Commercial applicants also need general liability insurance of at least $300,000 per occurrence or $600,000 aggregate (MSBOC's wording), with MSBOC listed on the policy so it is notified of any cancellation. Residential applicants only need proof of coverage, with no minimum amount set. Proof of workers' compensation is required if you have 5 or more employees.
| Fee | Commercial | Residential |
|---|---|---|
| Application | $400 | $50 |
| Renewal | $400 | $100 |
| Late fee | $50 | $10 |
| Additional classification | $100 | Not listed |
Licenses expire one year from the date of issuance. MSBOC allows late renewal for up to 180 days after expiration, and says that beginning in 2026 it sends annual renewal notices by email only, so keep the email on file current. Residential licenses issued on or after July 1, 2015 carry a continuing education requirement.
Public bids, subcontractors, and out-of-state firms
On public and private projects, a bid over $50,000 must show the contractor's current certificate number on the outside of the envelope, or a statement that the bid does not exceed $50,000. Public agencies may not consider a bid from a contractor without a Mississippi Certificate of Responsibility, and a contract awarded without one is null and void. Joint ventures without their own certificate list each member's number. If you are new to public bidding, read how to bid public construction projects and the Mississippi prevailing wage page.
It is unlawful to subcontract a portion of a project equal to or exceeding $50,000 to an unlicensed sub. Check every sub's certificate before you carry their number on a bid, and keep the lookup result in the sub file. Prequalifying subcontractors with a standard checklist makes that routine.
Mississippi has reciprocity agreements with boards in Alabama, Arkansas, California, Florida, Georgia, Louisiana, North Carolina, Ohio, South Carolina, and Tennessee, and each agreement covers only certain classifications. Reciprocity waives only the trade exam. The Law and Business exam is still required.
Penalties and local permits
Bidding commercial work without a certificate is a misdemeanor punishable by a fine of not more than $1,000 or up to six months in jail, and the Board can add a civil penalty of up to 3 percent of the total contract. Unlicensed residential work is a misdemeanor with fines of $100 to $5,000 or 30 to 60 days in jail, and the unlicensed contractor cannot sue to enforce the contract. That last point hits collections hard, and it also undercuts Mississippi mechanics lien leverage.
County and city building officials must refuse a residential building permit unless the applicant shows a license or an exemption. Residential contractors without a permanent Mississippi place of business or a commercial license also need a Department of Revenue permit before pulling building permits.

Use the MSBOC consolidated search at search.msboc.us. You can search by company name or license number and confirm classifications and status.
What exam do I need for a Mississippi contractor license?
All applicants pass the Mississippi Law and Business Management exam. Most classifications add a trade exam. PSI gives the exams, which are open book, and a NASCLA commercial general building score can replace the Building Construction trade exam.
How long is a Mississippi contractor license good for?

The remodeler license applies when improvements exceed $10,000, so a job of exactly $10,000 falls under the line. A job of $10,001 or more needs a license, and residential electrical, plumbing, HVAC, and mechanical work needs one at any amount.
