Mississippi Tiny Home Building Code Requirements Statewide

Mississippi Code Section 17-2-1 mandates that counties and municipalities adopt one of the last three editions of the IRC unless they opted out by November 2014. The 2018 and later IRC editions include Appendix Q, which provides specific provisions for dwellings 400 square feet or less on permanent foundations, addressing loft access, ceiling heights, emergency escape, and stair dimensions. Appendix Q applies only when a jurisdiction specifically adopts it. Tiny homes on wheels are regulated as RVs or manufactured housing rather than under the IRC. Local zoning controls minimum dwelling size, lot use, and whether tiny homes are permitted at all.

Building or occupying a tiny home without code compliance and permits can result in stop-work orders, occupancy denial, condemnation, and forced removal at owner expense.
