Louisiana Tiny Home Zoning Laws
Louisiana calls its counties "parishes," and that's not just terminology — it reflects a genuinely distinct legal tradition. Louisiana is the only US state built on a civil-law system rather than English common law, a legacy of its French and Spanish colonial history, and each of its 64 parishes holds its own separate zoning authority.7
- Louisiana's 64 parishes (not counties) each hold separate zoning authority, under a unique civil-law legal tradition.
- All parishes currently allow tiny homes in some form, generally under the statewide-adopted 2021 IRC.
- ADUs are already formally defined in the current building code — not a future update as older sources claim.
- Parish websites typically offer very little zoning detail online — a direct call or visit is often genuinely necessary.
- Local parishes can and do adopt more stringent requirements on top of the state baseline.
The practical takeaway: all parishes currently allow tiny homes in some form, and most follow the statewide-adopted 2021 IRC, but local governments can and do adopt more stringent requirements on top of it.4 ADUs are already formally defined in the Louisiana Residential Code 2021 (Chapter 2, Section R202) as a structure providing complete independent living facilities on the same lot as the primary dwelling, and must be built to the Louisiana State Uniform Construction Code with plan review and inspection by a registered LSUCCC inspector.9 Most parish government websites offer very little zoning detail online beyond that baseline, so a direct call or in-person visit to the parish planning office is often genuinely necessary here, more so than in most other states in this series.4
1. Parish Examples
| Parish | Notable Detail |
|---|---|
| Lafayette Parish | Allows tiny homes in residential zones with standard building code compliance1 |
| East Baton Rouge Parish | Permits tiny houses as ADUs on larger lots, with specific setback and size requirements1 |
| Calcasieu Parish | Supports tiny homes in rural areas, with particular attention to hurricane-resistant construction standards1 |
| St. Tammany Parish | Allows both permanent and mobile tiny homes in its mix of suburban and rural areas, with design standards limiting visual impact on natural surroundings1 |
| Iberia Parish | Welcomes tiny homes in agricultural zones, largely to support farmworker housing needs1,6 |
| Vermilion & Ascension Parishes | Allow tiny homes; both require standard building and zoning permits before installation or occupancy4 |
2. New Orleans Specifics
New Orleans defines several distinct residential zoning districts, each with its own height limits, setback requirements, and permitted uses, including Historic Urban Neighborhoods Residential Districts with rules tailored to preserve neighborhood character.3 ADU-style structures generally fall under Article 21 of the city's code, and like most of the state, homes on wheels are typically restricted to designated RV parks or manufactured housing communities rather than treated as legal ADUs.8
3. Homes on Wheels Face Consistent Restriction
Louisiana zoning codes classify most tiny houses on wheels strictly as RVs.6 Park model tiny homes specifically are classified under ANSI A119.5 standards and generally cannot serve as permanent ADUs, since Louisiana law requires legal dwellings to meet the 2021 IRC instead.8 To qualify as an ADU, a structure typically must be permanently anchored to a foundation and built to Appendix AQ safety standards.8
4. Real, Named Communities
Burleigh Plantation, founded by Karen McCoy in St. Landry Parish, is a real tiny home hamlet of 11 homes on 4 acres, built around a philosophy of community rather than isolation.5 Santosha Village is a sustainable farming community, RV park, and integrated campground with designs finalized for 2025.5
Research record: A previous version of this page described ADUs as not yet included in Louisiana's building code, expected in a future revision. We found and verified the actual current code language directly on UpCodes, which shows ADUs are already formally defined in the adopted 2021 Louisiana Residential Code; that forward-looking hedge was simply out of date. We have not separately confirmed how each individual parish's zoning ordinance treats ADUs beyond the baseline construction-code definition, since that remains genuinely parish-specific. Information last checked August 2026.
How to Verify Your Specific Situation
- Call or visit your target parish's planning office directly — online information is often genuinely sparse in Louisiana compared to other states.
- If in a hurricane-prone parish like Calcasieu, budget for wind-resistant construction requirements specific to that risk.
- Confirm whether your target parish has adopted the base 2021 IRC or a more stringent local variation.
- If considering a home on wheels, don't assume ADU flexibility extends to it — confirm RV park or manufactured housing community requirements directly.
