Tiny Homes in Louisiana: Laws, Rules and Communities

Updated November 4, 2026. Some laws may have changed since then. Confirm with your parish or city before you buy land or a home.

The short answer

Yes, you can live in a tiny home full time in Louisiana, on a permanent foundation and where local zoning allows it. Louisiana's statewide building code already includes the tiny house appendix, Appendix AQ, for homes of 400 square feet or less, not counting lofts, and every parish and city must enforce that code. For a tiny home on wheels, the state has no category of its own, so your parish or city decides where you can live in one. The state has proposed moving to the 2024 building codes on January 1, 2027, and a new law on manufactured and modular housing takes effect the same day. Louisiana has the 16th lowest cost of living of the 50 states, a flat 3 percent income tax, an effective property tax rate of 0.55 percent (13th lowest), and homeowners insurance averaging $2,020 a year.

On this page. Quick facts, the rules in plain words, where to start, living in Louisiana, communities and common questions.

In Louisiana, the state sets one building code for the whole state, and parishes and cities enforce it and decide zoning. A tiny home on a permanent foundation, anchored to a base built into the ground like a slab or piers, is a house under that code, and the code's tiny house appendix eases some rules for very small homes. A tiny home on wheels, built on a trailer so it can be towed, is harder. No state law gives it a category, so your parish or city decides.

This guide covers the state code and its tiny house appendix, permits in every parish, homes on wheels, camps, manufactured and modular homes, ADUs, septic, wells, flood and wind, and where to find a community.

Quick facts

  • On a foundation: a house under the Louisiana State Uniform Construction Code, which uses the 2021 International Residential Code.
  • Tiny house rules: Appendix AQ of the 2021 code, adopted statewide, for homes of 400 square feet or less, not counting lofts.
  • Code change ahead: the 2024 codes are proposed to take effect January 1, 2027. The proposal is not final, and a public hearing on changes to it is set for November 24, 2026.
  • Permits: every parish and city must enforce the state code, including outside city limits.
  • On wheels (built on a trailer): no category of its own in state law. Your parish or city decides where you can live in one.
  • ADUs (a second, smaller home on the same lot as a house): we found no statewide ADU law. The state code says an ADU must be built to the code, with plan review and inspection.
  • Septic: a permit from the state health officer, through your parish health unit, installed by a licensed installer.

Can you live in a tiny home full time in Louisiana?

Yes, on a permanent foundation where local zoning allows it. On wheels, it depends on your parish or city.

  • On a foundation, a tiny home is a house. It has to meet the state residential code, and Appendix AQ applies if it is 400 square feet or less, not counting lofts.
  • It needs public sewer or a permitted septic system.
  • On wheels, we found no state law that allows or bans living full time in one. Local rules decide, so ask your parish or city first.
  • A hunting or fishing camp exempt from the building code has to be one that is not used as a residence, so a camp is not a way around the code for full-time living.

The rules in plain words

Building code

Louisiana has one mandatory building code for the whole state, the Louisiana State Uniform Construction Code. For homes it uses the 2021 International Residential Code, minus its administrative and electrical parts, and it applies to new homes, reconstruction, additions to homes built to the residential code, and extensive alterations. The 2021 codes took effect January 1, 2023.

A change is on the way but not final. On August 20, 2026, the state's construction code commission published a proposal in the Louisiana Register to adopt the 2024 codes "with an effective date of January 1, 2027." On October 20, 2026, the commission published changes to the plumbing and electrical parts of the proposal and set a public hearing on them for November 24, 2026. As of November 1, 2026, no final rule has been published, and until one is, the 2021 code is the one in force. If you plan to apply for a permit around the turn of the year, ask your building official which edition your plans will be reviewed under.

The tiny house appendix

The national code has an optional appendix with rules for tiny houses, often called Appendix Q. In the 2021 code it is lettered Appendix AQ. Louisiana adopted it statewide along with the residential code, "with inspections on site and or in the manufacturing plant as required by" state regulations. That means a tiny home built in a factory can be inspected at the plant.

The appendix covers homes of 400 square feet or less, not counting lofts. It relaxes some of the main code's rules for them, mainly around lofts, including ceiling heights, compact stairs and ladders, guards and emergency escape openings. Ask your building official for the exact figures before you design a loft. If you would rather skip the loft, see tiny home layouts without a loft.

One detail of the 2027 proposal is not settled. In the 2024 national code, the tiny house appendix is lettered Appendix BB, not AQ. The proposed Louisiana rule pairs the 2024 residential code with "Appendix AQ, Tiny Houses." The October changes did not touch the residential code section, so the proposal still names Appendix AQ. The intent to keep a tiny house appendix looks plain, but which letter and text the final rule uses has not been decided. Builders planning for 2027 should ask the parish or city building official, or the commission, which version will apply.

Permits in every parish

Since 2007, every parish and city in Louisiana has had to enforce the state code, including in unincorporated areas. Act 881 of 2026 (HB 1186), signed June 9, 2026, rewrote the state's code law and kept that rule. It says municipalities and parishes "shall enforce only the Uniform Construction Code." A parish or city can enforce the code itself or contract with another public body or a licensed private inspector, so the office that issues your permit may be a third-party provider.

The rewritten law also says parishes and cities cannot require fire sprinklers in one and two family homes, and cannot require an architect's or engineer's stamp on plans for a one or two family home that fits the residential code's standard prescriptive rules.

Tiny homes on wheels

Louisiana law has no category of its own for a tiny home on wheels, and how one is treated is not settled. Three things point different ways.

  • The state code adopts the tiny house appendix and allows inspections in the factory, but the appendix is written for houses. We found no state rule that says whether a home on a trailer built to Appendix AQ counts as a house.
  • Local rules can be strict about anything that looks like an RV, including how long one may be lived in or stay parked in a flood zone. Ask your parish or city what applies to your lot.
  • Cities can allow RV parks as a use. New Orleans, for one, has zoning standards for RV parks, including spaces of at least 1,500 square feet where there are utility connections, and its RV park section sets no stay limit.

The sources we found lean toward a tiny home on wheels being handled locally like an RV, but no state rule says so. The label can decide where zoning lets you park it, so get your parish or city's answer in writing before you buy or build. A certified park model faces the same question.

We found no state rule on titling a tiny home on wheels. The Office of Motor Vehicles has a policy for homemade and shop-built trailers. For a homemade trailer built with parts from another vehicle, it asks for a permit to dismantle that vehicle or a licensed dismantler's receipt. For a shop-built trailer, it asks for a notarized builder's invoice and an affidavit that the trailer was not bought from a manufacturer. State Police assign a serial number to a trailer that has none. The policy does not mention tiny homes, so ask OMV how it will title yours before you build or buy.

Camps

State rules exempt farm structures and private hunting and fishing camps from the building code, under conditions. A camp qualifies only if it is not used as a residence, sits outside city limits, is not on the same property as a residence, and meets the rule's other conditions, and the owner files an affidavit in the parish conveyance records. A camp you live in full time is a residence, so the exemption does not apply to it.

Modular and manufactured homes

State law defines a modular home as a factory-built home built to the International Residential Code as adopted in Louisiana, the same code as a site-built house. A manufactured home is built to the federal HUD code instead.

Louisiana licenses manufactured and modular home installers, through the State Fire Marshal until the end of 2026. A 2026 law, Act 765 (SB 398), moves the state's manufactured and modular housing rules, including installer licensing, to a residential subcommittee of the State Licensing Board for Contractors starting January 1, 2027, and says the state's installation standards override local installation standards. If your home will be set up around that date, ask your dealer and installer which rules will apply. The act covers how a home is installed, not where it may go. We found no state law that limits a parish or city from restricting manufactured homes through zoning, so check local zoning.

ADU rules

We found no statewide ADU law in Louisiana. A bill filed in 2022 on building and repairing accessory dwelling units used as personal residences (HB 737) was referred to the House Commerce committee and never got a vote.

The state code does address ADUs. Louisiana's amendments to the residential code define an accessory dwelling unit as a complete, independent home on the same lot as a house and say it "shall be designed and constructed in accordance with the Louisiana State Uniform Construction Code," including plan review and inspection by a registered inspector. So a backyard tiny home used as a home needs permits like any house.

Whether you can build one is a local zoning question. New Orleans, for example, says in its zoning code that "No detached accessory structure may be used for habitation," though some districts allow more than one principal building on a lot. Ask your parish or city before you plan a backyard home, and check any deed restrictions or HOA rules too.

Septic

If the land is not on public sewer, you need a septic permit. The state rule says no one may install, alter or operate an individual sewage system without a permit from the state health officer, and parish health unit sanitarians run the permitting. A temporary permit comes first, and the final permit follows once the installation is checked. The installer must be licensed and must notify the parish health unit before installing. The permit rule weighs lot size along with soil and drainage when deciding whether a system can be approved. A combination license is required to install an aerobic treatment unit, and the Louisiana Department of Health says your installer should give you a maintenance contract.

Wells

A water well has to be drilled by a contractor licensed with the state. A household well does not need notice before drilling, but the state must be notified no later than 60 days after the well is finished, on its water well notification form. The program now sits with the Louisiana Department of Conservation and Energy.

Flood and wind

  • Louisiana's version of the residential code lets parish and city floodplain managers require extra height above the base flood elevation, called freeboard, but never less than the ASCE 24 standard. Ask your floodplain manager what applies to your lot.
  • State law bars parishes, and cities of 45,000 people or fewer, from enforcing the building code on a small detached accessory structure, up to 200 square feet, used with a home. Larger cities may enforce it, and the rule does not cover hurricane-prone areas where the code's design wind speed is 130 mph or more. FEMA's flood insurance program standards still apply. Ask your building official the design wind speed for your lot before you choose a home.

Where to start

  1. Not sure which office covers your land? USA.gov's local government finder points to a directory of Louisiana's parishes and cities, with their websites and contacts.
  2. Call the city planning department, or the parish if the land is outside city limits. Ask whether tiny homes and ADUs are allowed in that zone, and whether a tiny home on wheels can be lived in there. Get the answer in writing.
  3. Ask the building official, or the parish's contracted inspection provider, which code edition your plans will be reviewed under, and whether they will apply Appendix AQ to your home.
  4. Ask the floodplain manager for the flood zone and required elevation for the lot.
  5. If the land is not on sewer, contact the parish health unit about a septic permit before you buy.
  6. For a well, hire a licensed water well contractor.
  7. For a manufactured home, use a licensed installer, and ask which rules apply if setup is near January 1, 2027.
  8. For a tiny home on wheels, ask the Office of Motor Vehicles how it will be titled before you build or buy.
  9. Before buying land, check the flood map and ask about insurance.

  • Sunshine in New Orleans. 57 percent of possible sunshine, 101 sunny days a year
  • People 65 and older (Census estimates, 2024). 17.7 percent

Louisiana's cost of living is below the national average, and housing is the lowest of the cost measures in that index. The state income tax is a flat 3 percent, and the effective property tax rate is 0.55 percent. NerdWallet puts homeowners insurance at $2,020 a year with $400,000 in dwelling coverage for owners with good credit, below its national figure of $2,490. U.S. News ranks Louisiana 45th in health care and 46th in education, and WalletHub ranks it 49th happiest.

Rankings mix many factors, and statewide averages hide big differences between places. NerdWallet's city averages run from $2,280 a year in Bossier City to $4,925 in Kenner, and New Orleans averages $4,480, so look closely at the parish where you plan to live.

Tiny home communities in Louisiana

These communities come from their own websites. Rules, prices and openings change, so contact each one directly before you plan around it.

  • Vue Du Ville Tiny Home Community, Lafayette area. Sells homes on rented lots. Its FAQ says lot rent is $600 a month, residents must be 25 or older, and you can bring your own home subject to approval of its quality and age. One home listing shows $500 lot rent, so ask which figure is current.
  • Caribbean Country View Subdivision, on Highway 190 between Opelousas and Eunice. Rents tiny homes, cabins, apartments and RV spaces on long-term leases only. Its site lists 12-month leases from $650 to $850 a month with utilities included. It does not say whether you can bring your own tiny home.

Ask each one about year-round living, availability and current prices.

Frequently asked questions

Is it legal to live in a tiny house in Louisiana?

Yes, on a permanent foundation, if it meets the state residential code and local zoning, with sewer or a permitted septic system. Louisiana's code includes the tiny house appendix for homes of 400 square feet or less. For a tiny home on wheels, your parish or city decides.

Does Louisiana use Appendix Q for tiny houses?

Yes. Louisiana adopted the tiny house appendix statewide as Appendix AQ of the 2021 residential code. A proposal to move to the 2024 code on January 1, 2027 keeps a tiny house appendix, but the rule is not final, and which letter and text it will use is not settled.

Can I live in a tiny home on wheels in Louisiana?

It depends on your parish or city. State law has no category for a tiny home on wheels, and we found no state law that allows or bans living full time in one. Local rules decide, so get your parish or city's answer in writing.

Can I build an ADU in Louisiana?

It depends on your parish or city. We found no statewide ADU law in Louisiana. The state code says an ADU must be built to the code with plan review and inspection, and local zoning decides whether one is allowed. New Orleans' zoning code says no detached accessory structure may be used for habitation.

Do I need a septic permit for a tiny home in Louisiana?

Yes, if the land is not on sewer. You need a permit from the state health officer through your parish health unit, and a licensed installer must do the work. The permit rule weighs lot size along with soil and drainage when deciding whether a system can be approved.
