Building permits in New Orleans — Louisiana's largest city, coextensive with Orleans Parish under a consolidated city-parish government — are issued by the Department of Safety & Permits, enforcing the statewide LSUCC.
This guide covers what requires a permit, the One Stop App (onestopapp.nola.gov), fees, trade permits, and inspections — so your New Orleans project stays on track.
New Orleans is a hurricane- and flood-exposed city where FEMA Special Flood Hazard Areas, base-flood-elevation requirements, and wind-borne-debris provisions drive design. Much of the city also falls within local historic districts regulated by the HDLC or Vieux Carré Commission (VCC), which require separate design approval before a building permit. Confirm flood and historic-district status before applying.
Louisiana enforces a mandatory statewide building code — the Louisiana State Uniform Construction Code (LSUCC). Adopted under R.S. 40:1730.21 et seq. after Hurricane Katrina and administered by the Louisiana State Uniform Construction Code Council (LSUCCC) under the Office of State Fire Marshal (OSFM), the LSUCC adopts the 2021 I-Codes (IBC, IRC, IEBC, IPC, IMC, IFGC, IECC) with Louisiana amendments (effective Jan 1, 2023; 2024 editions under review) plus the National Electrical Code. Critically, no parish or municipality may adopt codes more or less stringent than the LSUCC — local jurisdictions administer permitting and inspections but enforce one consistent statewide code. Where a parish or municipality does not provide commercial plan review, the OSFM performs it.
What requires a building permit in New Orleans?
Under locally adopted codes, a permit is required for most construction activities:
Permit required
- New residential and commercial construction, additions, conversions
- Structural and load-bearing alterations
- Reroofing, windows, siding, and exterior modifications
- Electrical service changes and most wiring work
- HVAC installations, changeouts, and ductwork
- Plumbing alterations, repipes, water heaters
- Decks, porches, fences, patios, pools, garages
- Change of occupancy or use, sign installation
Typically exempt
- Painting, wallpapering, tiling, carpeting, cabinet installation
- Countertop replacement and similar finish work
- Minor repairs replacing existing materials in kind
- Small one-story detached accessory structures below the local size threshold (verify locally)
Exemptions are narrow and scope-specific. When unsure, confirm with the building department before starting — see the penalty note below.
Get the permit issued before starting work. Building without a permit in New Orleans can result in fines, stop-work orders, and mandatory removal of unpermitted work.

New Orleans trade permits
Electrical, plumbing, and mechanical work each needs its own permit and appropriately licensed tradespeople.
Electrical permits
Required for service installations, panel upgrades, solar PV, EV chargers, and most wiring alterations — performed by a contractor licensed by the LSLBC (Electrical classification). Louisiana enforces the National Electrical Code statewide through the LSUCC; commercial electrical subcontracts over $10,000 require a license.
Plumbing & gas permits
Required for new plumbing, repipes, water-heater changeouts, fixtures, backflow, and gas/sewer connections — performed by a contractor licensed through the Louisiana State Plumbing Board and, for commercial work, the LSLBC (Plumbing classification).
Mechanical (HVAC) permits
Required for HVAC installations, changeouts, ductwork, and venting — performed by a contractor licensed by the LSLBC (Mechanical classification). Commercial mechanical subcontracts over $10,000 require a license.
Miscellaneous & specialty
Fencing, pools, decks, sheds, and patio covers may require special permits depending on size and utility hookups. Demolition, sign, and right-of-way permits follow separate tracks.
Verify contractor licensing. Louisiana consolidates contractor licensing under a single agency, the Louisiana State Licensing Board for Contractors (LSLBC). A commercial license is required for projects $50,000+ (classified Building, Electrical, Mechanical, Plumbing, Specialty); a residential license for new 1–4 family dwellings over $75,000; and a Home Improvement Contractor (HIC) registration for residential remodeling between $7,500 and $74,999. Electrical, mechanical, and plumbing subcontractors need a license when their commercial work exceeds $10,000. Under Act 422 (effective Aug 1, 2025), all roofing work now requires a separate LSLBC roofing license regardless of project value. Plumbers are also licensed by the Louisiana State Plumbing Board. Verify licenses at lslbc.gov.
How to get a building permit in New Orleans
Confirm permit requirement & zoning
Contact the Department of Safety & Permits (see nola.gov / One Stop). Confirm zoning compliance, identify the correct permit type, and whether your project requires a permit. Verify any flood-zone (FEMA SFHA) and coastal/wind requirements before applying — these are common across Louisiana.
Prepare your application package
Assemble the permit application, site plan, construction drawings (sealed by a Louisiana-licensed design professional where required), scope and valuation, LSLBC contractor license, and proof of insurance.
Submit application & plans
Submit through the One Stop App (onestopapp.nola.gov). Select the correct permit type and upload required documents. Where the jurisdiction doesn't provide commercial plan review, the State Fire Marshal performs it.
Plan review & corrections
Staff reviews against the LSUCC. Typical review: varies by scope; historic-district and flood review common. Address any correction notices promptly.
Pay fees & receive permit
Pay permit fees upon approval. Print the permit and post it on-site before construction begins.
Schedule inspections
Schedule inspections through the One Stop App (onestopapp.nola.gov) or the Department of Safety & Permits. Typical checkpoints: footing/foundation, framing, rough-in MEP, insulation, final. A Certificate of Occupancy is required before occupancy.
