Do you need a building permit in Orleans Parish, Louisiana?
Yes. Orleans Parish building permits are issued by the City of New Orleans Department of Safety & Permits for the consolidated city-parish12. Louisiana requires local code enforcement procedures to include permit issuance, plan review and inspections for construction covered by the state uniform construction code1112. The statewide residential code applies to new construction, reconstruction, additions to homes previously built to that code, and extensive alterations13.
An owner-builder exemption concerns contractor licensing, not permission to skip the building permit or life-safety rules. A property owner may supervise work on a personal residence under the exemption, but must provide the prescribed affidavit, keep the house as a primary residence, and ordinarily may build only one residence during the applicable one-year period6. Licensed subcontractors still must satisfy their own licensing requirements6.
Who handles Orleans Parish building permits, and how do you reach them?
The City of New Orleans Department of Safety & Permits is the building-permit office for Orleans Parish1. The office is at 1340 Poydras St, Suite 800, New Orleans, LA 70112 and can be reached at (504) 658-72002. Applications can be started through the city's One Stop portal2. Plumbing permits are issued separately by the Sewerage and Water Board rather than Safety & Permits2.
Before preparing plans, identify the parcel's zoning district and intended use. The New Orleans City Planning Commission handles zoning-map changes, amendments, appeals and subdivisions; its office is at 1300 Perdido Street, 7th Floor, New Orleans, LA 70112, and its phone number is (504) 658-70337. If the proposal needs a zoning change, subdivision approval or an interpretation of permitted use, start with City Planning before finalizing a building-permit set7.
Does Orleans Parish have zoning?
Yes. Land use in Orleans Parish is governed by the New Orleans Comprehensive Zoning Ordinance, and the applicable use and dimensional controls depend on the parcel's zoning district and required city approvals34. The ordinance includes Rural Development Districts as well as use standards, so a parcel that looks agricultural or low-density is still within the zoning system14.
Setbacks, building height, lot coverage and any minimum dwelling size must be checked against the parcel's local district rules; Louisiana does not supply one statewide number for those municipal standards15161718. Creating or modifying lots is also regulated: the City Planning Commission administers subdivision rules for new lots, changed lots and new streets19. Ask City Planning to confirm the zoning district, allowed use, dimensional table and any overlay or approval that affects the site7.
How do septic permits work in Orleans Parish?
An individual sewerage system in Orleans Parish needs a permit from the State Health Officer before it is installed, altered or operated5. Louisiana Department of Health sanitarians in parish health units operate the onsite-treatment permitting system20. A temporary installation permit depends on a finding that connection to community sewer is not feasible and that the soil, drainage, lot dimensions and related site factors will not create a nuisance or public-health hazard5.
Final approval follows compliance verification by an onsite inspection, installer certification, or both5. No mapped Orleans Parish soil is rated without severe limitations for a conventional drain field10. If Sewerage and Water Board service is available, private water or sewer lines require a licensed master plumber and proof of a private-plumbing permit before public work proceeds21. Confirm sewer availability and the connection route before treating a lot as buildable.
Can you live in an RV or tiny home on your land in Orleans Parish?
We could not confirm a general Orleans Parish rule allowing full-time RV occupancy on a private parcel or a complete tiny-home occupancy rule. Because New Orleans zoning is district-specific, ask the City Planning Commission whether the proposed vehicle or dwelling is an allowed principal or accessory use at the address and what approvals apply47. The ordinance's use standards and residential district provisions—not a statewide camping rule—control the local land-use question14.
Do not treat an owner-builder exemption as permission for an RV, tiny home or unpermitted structure. That exemption is limited to contractor licensing for an owner's personal residence and leaves permit, zoning, health and life-safety requirements in place6. We also could not confirm a complete parishwide minimum-home-size rule. City Planning should confirm the district's use, setback, height, lot-coverage and dwelling standards before purchase or design1815.
What are the steps to build a home in Orleans Parish?
- Ask the City Planning Commission to confirm the parcel's zoning district, allowed residential use, dimensional standards and any subdivision approval47.
- Confirm public water and sewer availability; if community sewer is not feasible, contact the Louisiana Department of Health about an individual-system permit and site review520.
- Check flood constraints with Safety & Permits because the department serves as the city's Floodplain Administration and development must meet applicable FEMA map elevations and city flood rules22.
- Submit the building-permit application to Safety & Permits through the city portal12.
- Obtain separate trade approvals as required; plumbing permits come from the Sewerage and Water Board2.
- If creating or changing a driveway connected to a public street, obtain the city driveway or curb-cut permit before that work9.
- Complete the required code inspections before occupancy12.
What should you check before buying land in Orleans Parish?
Start with zoning, sewer and flood exposure. New Orleans use and dimensional rules vary by district, and the city's subdivision rules cover the creation or modification of lots419. No mapped Orleans Parish soil is rated without severe drain-field limitations, while an individual system is allowed only through the state permitting process and when community sewer is unavailable or infeasible105.
Check access too. Installing, replacing or repairing a driveway connected to a New Orleans public street requires a city permit, and the application carries a $100 non-refundable fee plus possible inspection or reinspection charges9. Development subject to floodplain administration must meet applicable FEMA elevation standards and city flood rules22. For a private well, Louisiana requires a licensed driller and registration after completion; domestic wells follow the applicable post-installation notification path rather than the ordinary advance-notification rule8. Finally, obtain parcel-specific insurance and tax quotes rather than relying only on parish averages.
Watch-outs
- An owner-builder contractor-licensing exemption does not waive Orleans Parish building permits, zoning, health rules or life-safety requirements6.
- No mapped Orleans Parish soil is rated without severe limitations for a conventional septic drain field, so confirm sewer availability or state approval before relying on an onsite system105.
- Safety & Permits serves as the city's Floodplain Administration, and applicable development must meet FEMA map elevations and city flood rules22.
