Mississippi Contracting Law & Unlicensed Practice
Mississippi law ties the Certificate of Responsibility to bidding and bars an unlicensed contractor from enforcing a covered contract. This chapter covers the bidding requirement, the unlimited-license rule in practice, the enforcement bar, and the residential thresholds.
Certificate of Responsibility required to bid
Under the Mississippi Code, Title 31, Chapter 3, a contractor must hold a current Certificate of Responsibility to bid on or perform covered commercial work of $50,000 or more, whether public or private. The certificate number is required on the bid, and a bid submitted without a valid Certificate of Responsibility can be rejected. The requirement reaches the qualifying individual who holds the certificate for the company.
One unlimited license, no tiers
Because Mississippi issues a single unlimited commercial license rather than A/B/C/D tiers, a qualified commercial contractor is not boxed into a per-project dollar tier on the license. This differs from tiered states where a licensee must upgrade a classification to take larger single contracts. In Mississippi the key line is the $50,000 threshold that triggers the Certificate of Responsibility, not a set of ascending tier caps.
Unlicensed contractors cannot enforce covered contracts
A contractor who performs covered work without the required license or Certificate of Responsibility generally cannot sue to enforce the contract in Mississippi. Together with civil penalties for unlicensed contracting, this makes proper licensure a precondition to collecting on covered work. On the residential side, the same discipline applies: a residential builder license is needed above $50,000 and a remodeler license above $10,000 before contracting.
