Building permits across Orleans Parish — coextensive with the City of New Orleans 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 Orleans Parish project stays on track.
Orleans Parish and the City of New Orleans are the same consolidated government; the Department of Safety & Permits issues building, electrical and mechanical permits parish-wide through the One Stop App, and the Sewerage and Water Board issues plumbing permits. Much of the parish lies in FEMA flood zones and within local historic districts (HDLC / Vieux Carré Commission) requiring separate design approval. Confirm flood and historic-district status before applying.
Louisiana enforces a mandatory statewide building code — the Louisiana State Uniform Construction Code (LSUCC). Adopted after Hurricane Katrina, the code law was re-enacted by Act 881 of 2026 as R.S. 37:3727 et seq., and the code is now overseen by the Louisiana Uniform Construction Code Commission (LUCCC) in the governor’s office, which replaced the former LSUCC Council. The code in force is the 2021 I-Codes (IBC, IRC, IEBC, IPC, IMC, IFGC) with Louisiana amendments, effective 1 January 2023, with the 2021 IECC from 1 July 2023 and the 2020 National Electrical Code; the 2024 I-Codes and the 2023 NEC take effect on 1 January 2027. Parishes and municipalities enforce only the statewide code (R.S. 37:3737) — local jurisdictions administer permitting and inspections. The city’s Department of Safety & Permits has its own Plan Review Division; the State Fire Marshal separately reviews plans for life safety on buildings other than one- and two-family dwellings (R.S. 40:1574).

Call 1-855-478-4290 →Orleans Parish 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 an electrician holding a City of New Orleans electrical license, renewed annually, and, for electrical work of $10,000 or more, an LSLBC (Electrical classification) license. Louisiana enforces the National Electrical Code statewide through the uniform code.
Plumbing & gas permits
Required for new plumbing, repipes, water-heater changeouts, fixtures, backflow, and gas/sewer connections — issued by the Sewerage and Water Board, and filed only by an Orleans Parish licensed master plumber registered with S&WB. Plumbers are licensed by the State Plumbing Board of Louisiana (whose duties move to the LSLBC on 1 January 2027 under Act 908 of 2026), and plumbing work of $10,000 or more also needs the LSLBC Plumbing classification. Plumbing inspections are requested through S&WB.
Mechanical (HVAC) permits
Required for HVAC installations, changeouts, ductwork, and venting — performed by a contractor holding a City of New Orleans mechanical contractor license and, for mechanical work of $10,000 or more, an LSLBC (Mechanical classification) 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.

A commercial license is required for projects $50,000+ (classified Building, Electrical, Mechanical, Plumbing, Specialty); a residential license for a new residential structure of $50,000 or more; and a Home Improvement license for residential improvement or repair work from $7,500 up to $50,000. Electrical, mechanical and plumbing work of $10,000 or more needs a license in that classification (R.S. 37:2150.1). Since 1 January 2026, residential roofing work of $7,500 or more needs the Residential Roofing or Residential Construction classification (R.S. 37:2156.4, from Act 422 of 2025). Plumbers are also licensed by the State Plumbing Board of Louisiana until its duties move to the LSLBC on 1 January 2027. In New Orleans, electricians and mechanical contractors also need a city trade license. Verify licenses at lslbc.gov.
How to get a building permit in Orleans Parish
Confirm permit requirement & zoning
Contact the Department of Safety & Permits ((504) 658-7200; Building Division (504) 658-7130). Confirm zoning compliance, identify the correct permit type, and confirm whether your project requires a permit. Verify any flood-zone (FEMA SFHA) and coastal/wind requirements before applying.

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.
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.
