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

Yes. Jefferson Parish requires a building permit for new construction and most other work under Louisiana's State Uniform Construction Code1. Statewide, Louisiana requires a permit for new construction built to the residential code, reconstruction, additions to homes previously built under the International Residential Code, and "extensive alterations" defined as work covering more than 50 percent of a dwelling unit's total area2. The parish's Building Permits Department, formerly called the Department of Inspection and Code Enforcement, enforces this in unincorporated Jefferson Parish3. The department also requires a standalone permit before replacing 50 percent or more of a roof covering on a one- or two-family home in unincorporated Jefferson Parish3.

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

The Jefferson Parish Building Permits Department, whose mission is to ensure compliance with the parish's structural-development laws, runs two offices: East Bank, at 1221 Elmwood Park Boulevard, Suite 101, Jefferson, and West Bank, at 1855 Ames Boulevard, Suite A, Marrero3. Call the East Bank office at 504-736-6957 with questions about commercial or residential permitting requirements3. The department recently created a Permit Navigators team responsible for seeing each permit through the process and serving as a point of contact for applicants, so ask to be connected to one if your project is complex3. Confirm your parcel's zoning district with the Planning Department before you apply, since a building permit application needs zoning approval124.

Does Jefferson Parish have zoning?

Yes. Jefferson Parish administers zoning parish-wide through its own Comprehensive Zoning Ordinance, run by the Planning Department, rather than relying on a separate town or township layer4. That means questions about RV placement, tiny homes, minimum home size and setbacks are answered by that ordinance and the zoning district your parcel sits in, not by a single parish-wide yes-or-no rule4. Reach the Planning Department at 504-736-6320 to find out which zoning district covers your parcel and what it allows12. Because district rules vary across the parish, don't assume a use is allowed just because a neighboring parcel has it.

How do septic permits work in Jefferson Parish?

Septic permitting in Jefferson Parish is a state, not a parish, function: the Louisiana Department of Health's Onsite Wastewater Program operates through sanitarians at the Jefferson Parish Health Unit5. No one may install, alter or operate an individual sewerage system anywhere in Louisiana without a permit from the state health officer, and approved plans and specifications are part of that permit13. A septic tank system may be used only where a community-type sewerage system is not available14, and an individual mechanical treatment plant is allowed only when the state health officer determines a conventional system would not function properly15. That determination matters here: 0% of Jefferson Parish's soils rate favorably for a conventional septic drain field in the USDA soil survey, so plan on a site evaluation and likely an engineered or mechanical system rather than a standard trench field7. After installation, final approval requires either an on-site state inspection or a completed "Certification by Installer" form from a licensed installer16. Start the process with the Jefferson Parish Health Unit's environmental health service17.

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

Whether an RV or tiny home can sit on your land in Jefferson Parish depends on the zoning district your parcel falls in under the parish's Comprehensive Zoning Ordinance, not on one parish-wide answer4. Louisiana's rules for the Office of State Parks set stay limits and reservation requirements at state park campgrounds, but those rules govern visits to state parks, not occupancy on private land, so they don't settle this question for a homestead parcel18. A manufactured or mobile home you place on the property still has to meet that zoning district's standards, which the Planning Department administers412. Call the Planning Department for your specific parcel before assuming an RV or tiny home is allowed12.

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

  1. Confirm your parcel's zoning district with the Jefferson Parish Planning Department, since the parish's own Comprehensive Zoning Ordinance controls what you can build and where412.
  2. If your site will use a septic system, contact the Jefferson Parish Health Unit for the required state permit and site evaluation before installing anything, and confirm a community sewer isn't available first171314.
  3. If your parcel is in a mapped floodway, check with the parish's Floodplain Management & Hazard Mitigation office; Louisiana's no-rise rules require your project to show no added flood-height impact, or go through a floodway revision, before a permit issues1920.
  4. If your driveway will connect to a state highway rather than a parish road, get a signed and numbered Access Connection Permit from LaDOTD before starting construction21.
  5. Submit your building permit application, with zoning approval attached, to the Building Permits Department's East Bank or West Bank office3.
  6. Before you close in walls, make sure your septic system's final inspection or installer certification is on file and your required building inspections have passed1622.

What to check before you buy land in Jefferson Parish

Home insurance runs high here, with a typical policy costing $3,556 a year, reflecting the parish's flood and hurricane exposure11. Check flood risk directly: if a parcel sits in a mapped regulatory floodway, Louisiana's no-rise certification rules require showing zero added flood-height impact, or a floodway revision, before a permit issues, and the parish's Floodplain Management & Hazard Mitigation office can tell you whether your lot is affected2019. With 0% of the parish's soils rating favorably for a conventional septic drain field, budget for an engineered or mechanical system and a site evaluation if the lot isn't on a community sewer714. Jefferson Parish is dense and largely suburban, at about 1,402 people per square mile, though its southern reaches are far more rural, so check the zoning district for that specific parcel before assuming what's allowed234. Property taxes run a low effective 0.5% rate, with a median bill around $1,265 a year on the typical home910.

Watch-outs

  • Jefferson Parish's owner-builder permit exemption is unconfirmed in our research; ask the Building Permits Department directly before assuming you can pull your own permit63.
  • Zoning in Jefferson Parish comes from the parish's own Comprehensive Zoning Ordinance and varies by district, so never assume a parcel is unrestricted for an RV, tiny home or setback question without checking with the Planning Department412.
  • A driveway or access connection onto a Louisiana state highway needs its own signed and numbered LaDOTD Access Connection Permit before construction begins, separate from any parish building permit21.
