DEPENDS ON LOCATION
Louisiana — Parish-based local control, but a real statewide tiny-home building code exists (verified 2026-08)
Tiny home on wheelsRegulation is set by parish rather than county, with no statewide tiny-home-on-wheels law; rural parishes are generally more permissive than the New Orleans and Baton Rouge metro areas. THOWs are generally classified as RVs/park trailers under ANSI A119.5 or HUD standards, restricted to designated RV parks or manufactured-housing communities in most parishes, including New Orleans and St. Tammany Parish.
ADU / accessory unitThis adds an important confirmed fact: the Louisiana State Uniform Construction Code Council has adopted IRC Appendix Q for tiny homes 400 sq ft or less, and under La. R.S. 40:1730.28 this is mandatory statewide and cannot be weakened by parish amendments — a real statewide building-code floor, distinct from ADU zoning permission itself, which remains local. Orleans Parish (New Orleans) is comparatively progressive on ADUs under its Comprehensive Zoning Ordinance (Article 21); East Baton Rouge Parish supports them via conditional-use permits; Lafayette Parish is stricter, often capping at 500 sq ft.
Minimum square footageAppendix Q sets a statewide 400 sq ft definition for tiny homes; local minimums for standard dwellings vary by parish
Foundation requirementCoastal and flood-zone parishes carry elevation and flood-resistant construction requirements on top of the statewide 130–150 mph wind-load standard
Local notesIf you're near the coast, budget for flood-zone elevation requirements the way a Florida buyer would budget for hurricane code. Pending 2026 legislation aims to standardize ADU rules statewide but had not passed as of this review.
!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.
