How permitting works in Mississippi

Local permits; state fire code for public buildings. In Mississippi, building permits come from cities and counties, and the State Fire Marshal's code covers state-owned and public-assembly buildings. Residential contractors need a state license for new homes over $50,000 and remodels over $10,000.

A county name is only a geographic starting point. Depending on the address, a city, town, borough, township, or county office may issue your permit. How to check who issues your permit.
