Tiny Homes Zoning — State ProfileReviewed 2026-08-23
Can you put a tiny home in Mississippi?
Current tiny-home-on-wheels and ADU rules for Mississippi, sourced and dated — plus verified local builders.
GENERALLY ALLOWED
Mississippi — Broadly permissive outside cities, with real named counties (verified 2026-08)
Tiny home on wheelsNo statewide tiny-home-on-wheels law; many counties have minimal zoning outside incorporated towns, consistent with the pattern across much of the rural South. Two counties (Warren and Adams) are documented to have opted out of the statewide building code entirely.
ADU / accessory unitCounties with more formal paths include Jackson, DeSoto, Harrison, Hinds, and Forrest, which generally require a building permit and basic safety-code compliance; many other rural counties have no building department at all. Hinds County has traditionally used 256 sq ft as an informal minimum-dwelling-size benchmark, though this is shifting as more jurisdictions adopt modern codes. Post-Katrina 'Katrina cottages' (300–600 sq ft) set an early precedent for small permanent housing in the state, though durable zoning reform has been slow to follow.
Minimum square footageNone outside city limits in most counties; Hinds County's traditional benchmark is 256 sq ft
Foundation requirementDepends on county; wheeled units are commonly accepted in unzoned rural areas
Local notesAs with Alabama, absence of county zoning doesn't remove septic, well, or floodplain permitting requirements. Jackson, DeSoto, Harrison, Hinds, and Forrest counties are the most concrete, named starting points.
!Zoning is set by your specific city or county, not the state as a whole. Use this as a starting point, then confirm with the local building or planning department before you buy land or start a build. Not legal advice.
