Unincorporated Lafourche Parish, Louisiana requires a building permit for new homes, additions, and modular or manufactured home placement through the parish Permits & Planning Department1. The unincorporated parish has no zoning regulations, but subdivision review, floodplain rules, building codes, and state septic permits still apply2345. An owner may apply as a residential owner-builder, but that status does not waive permits, inspections, licensing, or construction law6.

Do you need a building permit in Lafourche Parish, Louisiana?

Yes. Lafourche Parish's Permits & Planning Department issues building permits for new residential construction, additions, and modular or manufactured home placement in unincorporated areas under Louisiana's statewide construction-code system110. The parish publishes permit forms and checklists online, and an application becomes void if work does not begin within 180 calendar days or is suspended or abandoned for 180 calendar days11. The residential application includes an owner-builder signature option, but that option does not exempt the project from permits, inspections, licensing, or applicable construction laws6. Flood review can materially change a rebuilding project: in a Special Flood Hazard Area, damage costing at least 50% of the structure's pre-damage market value may require elevation, retrofitting, or other changes to comply with the floodplain ordinance4.

Who is the Lafourche Parish building department, and how do you reach them?

The Permits & Planning Department, at 4876 LA-1, Raceland, LA 70394, phone 985-537-7603, is the building-permit office for unincorporated Lafourche Parish12. Its staff include permit technicians, plan reviewers, inspectors, and floodplain managers, and office hours are 7:30am to 4:30pm Monday through Thursday12. Applications can be submitted through mypermitsnow.org, and applications require a current Entergy or SLECA bill where applicable as of March 16, 20261211. Call the department before finalizing plans to confirm the current checklist, required trade permits, flood-zone documents, inspections, and fees; we could not confirm a complete parish fee schedule.

Does Lafourche Parish have zoning?

No. Unincorporated Lafourche Parish has no zoning regulations, and its Planning Department does not determine land use through zoning213. As a result, parish zoning sets no minimum dwelling size, minimum lot size, setback, lot-coverage limit, or building-height limit there, and it does not restrict an RV, tiny home, manufactured home, accessory dwelling, or temporary camping as a land use8. That answer does not eliminate other reviews: new subdivisions, family subdivisions, re-divisions, mobile-home parks, and RV parks go before the Lafourche Parish Planning Commission3. Family-subdivision applications also receive health, planning, floodplain, addressing, and public-works reviews3. Incorporated municipalities may have their own zoning districts and standards under Louisiana's local zoning framework, so verify the parcel's jurisdiction before relying on the unincorporated-area answer14.

How do septic permits work in Lafourche Parish?

Louisiana, rather than Lafourche Parish government, controls individual sewerage permits through the state health officer and the local Parish Health Unit715. A state permit and approved plans are required before installing, altering, or operating an individual sewerage system5. A temporary installation permit depends on community sewer being infeasible and on soil, drainage, lot dimensions, and related site factors not being likely to create a nuisance or health hazard5. Final approval requires compliant installation verified by an on-site inspection and/or a licensed installer's certification, which must be submitted within 15 days after completion5. Individual sewage disposal can serve qualifying rural tracts, but the system still must meet state health requirements16. No Lafourche Parish soil is rated free of severe limits for a conventional drain field, so obtain the health review before treating any parcel as buildable9.

Can you live in an RV or tiny home on your land in Lafourche Parish?

Unincorporated Lafourche Parish does not use zoning to restrict RV occupancy, tiny-home occupancy, manufactured-home occupancy, accessory dwellings, or temporary camping on a parcel8. That land-use answer does not waive building permits for structures, state approval for an individual sewerage system, or floodplain requirements154. Mobile-home parks and RV parks also remain subject to Planning Commission review even though the unincorporated parish has no zoning3. Before occupying a small home or RV, ask Permits & Planning how the proposed unit will be classified for building, utility, addressing, and flood review, and ask the Lafourche Parish Health Unit what sanitation arrangement it will approve1215.

Building a home in Lafourche Parish: the steps, in order

  1. Confirm that the parcel is in unincorporated Lafourche Parish before relying on the parish's no-zoning answer2.
  2. If land will be divided, submit the subdivision or re-division to the Planning Commission before designing around new lot lines3.
  3. Ask the Lafourche Parish Health Unit to evaluate sewer availability and the proposed individual sewerage system, then obtain the state permit and plan approval before installation5.
  4. Confirm the flood zone and elevation requirements with Permits & Planning before finalizing the site plan412.
  5. Submit the building application and current Entergy or SLECA bill, where applicable, through Permits & Planning or mypermitsnow.org1112.
  6. If applying as an owner-builder, use the residential owner-builder signature option but do not assume it waives any permit, inspection, licensing, or code requirement6.
  7. Complete required building inspections and the state's final septic verification before occupancy175.

What to check before you buy land in Lafourche Parish

Check septic feasibility first because none of Lafourche Parish's soil is rated free of severe limitations for a conventional drain field9. Check whether the parcel lies in a Special Flood Hazard Area and whether existing damage or planned work will trigger elevation, retrofitting, or other floodplain compliance4. If the tract will be divided, confirm Planning Commission approval and the health, drainage, access, and utility reviews that can apply even without zoning318. A driveway connecting to a state highway requires a signed and numbered LaDOTD access-connection permit before construction19. A new domestic well must be installed by a licensed water-well contractor and registered after completion, with domestic wells following the applicable post-installation notification rules20. Typical home insurance is about $3,245 per year, while the effective property-tax rate is about 0.5% and the median annual bill is about $951212223.

Watch-outs

  • In a Special Flood Hazard Area, damage costing at least 50% of a building's pre-damage market value may require elevation, retrofitting, or other floodplain compliance4.
  • No parish zoning does not mean no rules inside any city or town in Lafourche Parish; confirm your parcel is unincorporated before assuming these answers apply2.
  • A septic permit is required before installation, alteration, or operation, and final approval requires state verification of compliant installation5.
