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

Yes. Lafourche Parish administers permits for home and business construction, and the permit application requires job-site access during normal business hours for inspections16. The parish enforces the adopted residential, building, mechanical, existing-building, fuel-gas, plumbing, and electrical codes listed in its code notice2. Residential permit fees are $0.30 per square foot with a $150 minimum; commercial fees are $0.50 per square foot with a $200 minimum, and the fees are non-refundable13. An owner-builder may self-contract by submitting the required subcontractor/supplier list and affidavit claiming a licensing exemption10. The residential application offers an owner signature option for owner/builders, but that option does not exempt the work from permits, inspections or applicable construction laws14. A farmer's agricultural construction exemption concerns contractor licensing and does not waive health or life-safety requirements15.

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

The Lafourche Parish Permits & Planning Department, at 4876 LA-1, Raceland, LA 70394, phone 985-537-7603, handles building permits16. Its staff include permit technicians, plan reviewers, inspectors, and floodplain managers, and office hours are 7:30am to 4:30pm Monday through Thursday16. Applications can be submitted through mypermitsnow.org16. A residential applicant must first obtain a completed and signed 911 Addressing form, then submit flood-zone documents, a permit application, land verification, a site plan, plans, and Board of Health approval when applicable17. Permit applications also require a current Entergy or SLECA bill when applicable18.

Does Lafourche Parish have zoning?

No. Unincorporated Lafourche Parish has no parish zoning regulations, and the Planning Department does not determine land use through zoning3819. Parish zoning therefore sets no minimum dwelling size, minimum lot size, setback, lot-coverage limit, or building-height limit there, and does not restrict an RV, tiny home, manufactured home, accessory dwelling, or temporary camping as a land use11. Subdivision, floodplain, health, and construction requirements still apply3. Public subdivisions or redivisions of six lots or more require plats showing details such as lot dimensions, elevations, drainage, easements, and utility servitudes4. Smaller administrative divisions request confirmation that listed utility services are available, but the form does not require every parcel to connect to public water or sewer20.

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 Unit921. A state permit and approved plans are required before installing, altering, or operating an individual sewerage system7. 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 hazard7. 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 completion7. Individual sewage disposal can serve qualifying rural tracts, but the system still must meet state health requirements22. 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 buildable12.

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 parcel11. That land-use answer does not waive construction permits, state approval for an individual sewerage system, inspections, or floodplain requirements1765. Mobile-home parks and RV parks remain subject to Planning Commission review23. Before occupying a small home or RV, ask Permits & Planning how the unit will be classified for building, utility, addressing, and flood review, and ask the Lafourche Parish Health Unit what sanitation arrangement it will approve1621.

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

  1. Confirm that the parcel is in unincorporated Lafourche Parish before relying on the no-zoning answer8.
  2. If land will be divided, submit the subdivision or redivision to the Planning Commission before designing around new lot lines23.
  3. Ask the Lafourche Parish Health Unit to evaluate sewer availability and the proposed individual sewerage system, then obtain state approval before installation7.
  4. Obtain the signed 911 Addressing form and assemble the site plan, land verification, plans, flood documents, and any applicable Board of Health approval17.
  5. Submit the permit application and current Entergy or SLECA bill, when applicable, through Permits & Planning or mypermitsnow.org1816.
  6. If self-contracting, include the subcontractor/supplier list and affidavit claiming a licensing exemption10.
  7. Present the second elevation form before requesting a foundation inspection24. Give inspectors job-site access, complete the required flood-elevation documentation, and obtain final septic verification before occupancy657.

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 field12. Check whether the parcel lies in a Special Flood Hazard Area; the parish requires staged elevation documents and a final elevation certificate before occupancy for covered construction, while an affidavit may be used outside that area, and an additional 1 foot of freeboard may be required on structures5. Owners rebuilding a home in a Special Flood Hazard Area after damage costing 50% or more of its pre-damaged market value must comply with the parish floodplain ordinance25. If the tract will be divided, confirm Planning Commission review and the health, drainage, access, and utility documentation that may apply even without zoning420. The agricultural exemption covers contractor licensing for qualifying farm construction, not health or life-safety codes15. A driveway connecting to a state highway requires a signed and numbered state access permit before construction26. 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 $951272829.

Watch-outs

  • Flood-zone construction may require elevation documents at multiple stages and a final elevation certificate before occupancy5.
  • No parish zoning does not answer the rules inside any city or town in Lafourche Parish; confirm the parcel is unincorporated before relying on these answers3.
  • A septic permit is required before installation, alteration, or operation, and final approval requires state verification of compliant installation7.
