Building permits, zoning and land rules 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 inspections^1,5. 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-refundable⁴. An owner-builder may self-contract by submitting the required subcontractor/supplier list and affidavit claiming a licensing exemption⁸. 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 laws¹¹. A farmer's agricultural construction exemption concerns contractor licensing and does not waive health or life-safety requirements¹².

The Lafourche Parish Permits & Planning Department, at 4876 LA-1, Raceland, LA 70394, phone 985-537-7603, handles building permits¹. Its staff include permit technicians, plan reviewers, inspectors, and floodplain managers, and office hours are 7:30am to 4:30pm Monday through Thursday¹. Applications can be submitted through mypermitsnow.org¹. 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 applicable¹. Permit applications also require a current Entergy or SLECA bill when applicable¹.

No. Unincorporated Lafourche Parish has no parish zoning regulations, and the Planning Department does not determine land use through zoning³. 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 use⁹. 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 servitudes³. 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 sewer¹³.

Louisiana, rather than Lafourche Parish government, controls individual sewerage permits through the state health officer and the local Parish Health Unit^7,14. A state permit and approved plans are required before installing, altering, or operating an individual sewerage system⁶. 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 hazard⁶. 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 completion⁶. Individual sewage disposal can serve qualifying rural tracts, but the system still must meet state health requirements¹⁵. 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 buildable¹⁰.

Unincorporated Lafourche Parish does not use zoning to restrict RV occupancy, tiny-home occupancy, manufactured-home occupancy, accessory dwellings, or temporary camping on a parcel⁹. That land-use answer does not waive construction permits, state approval for an individual sewerage system, inspections, or floodplain requirements^1,4,5,6. Mobile-home parks and RV parks remain subject to Planning Commission review³. 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 approve^1,14.

1. Confirm that the parcel is in unincorporated Lafourche Parish before relying on the no-zoning answer³.
2. If land will be divided, submit the subdivision or redivision 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 state approval before installation⁶.
4. Obtain the signed 911 Addressing form and assemble the site plan, land verification, plans, flood documents, and any applicable Board of Health approval¹.
5. Submit the permit application and current Entergy or SLECA bill, when applicable, through Permits & Planning or mypermitsnow.org¹.
6. If self-contracting, include the subcontractor/supplier list and affidavit claiming a licensing exemption⁸.
7. Present the second elevation form before requesting a foundation inspection⁴. Give inspectors job-site access, complete the required flood-elevation documentation, and obtain final septic verification before occupancy^4,5,6.

Check septic feasibility first because none of Lafourche Parish's soil is rated free of severe limitations for a conventional drain field¹⁰. 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 structures⁴. 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 ordinance³. If the tract will be divided, confirm Planning Commission review and the health, drainage, access, and utility documentation that may apply even without zoning^3,13. The agricultural exemption covers contractor licensing for qualifying farm construction, not health or life-safety codes¹². A driveway connecting to a state highway requires a signed and numbered state access permit before construction¹⁶. 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 $951¹⁰.
