New Orleans, Louisiana Building Permit Guide

Building permits in New Orleans are issued by the Department of Safety and Permits at 1340 Poydras Street, Suite 800, New Orleans, LA 70112 ((504) 658-7200, 9am–5pm Monday to Friday), through the city's One Stop App. Plumbing permits are the exception: they are issued by the Sewerage and Water Board. New Orleans is coextensive with Orleans Parish under a consolidated city-parish government — there is no separate parish authority to consider, which removes one question and leaves two much harder ones: flood and historic review.

This guide covers the department and how to reach it, the local conditions that shape a filing here, what permits cost and who may pull them, and how inspections are booked. Rules that apply everywhere in Louisiana are summarized in each section, with a link to the full statewide explanation.

This guide covers work in New Orleans, which is coextensive with Orleans Parish.

What requires a building permit in New Orleans?

Under the LSUCC as administered by the city, a permit is required before most construction, alteration, demolition, repair, relocation, change of occupancy and trade work begins.

Exemptions are narrow and local, and an exemption from a building permit is not an exemption from zoning, setbacks, floodplain rules, utility approval or a fire authority review. Confirm scope with the department before work starts rather than after.

Which code edition applies

New Orleans enforces the statewide LSUCC. The city does not set the technical standard and cannot vary it, so the building code answer here is the Louisiana answer. What is distinctively local is the combination of flood elevation requirements, historic design review, and the zoning framework of the Comprehensive Zoning Ordinance — and those three, not the code, are where New Orleans projects are decided.

Every Louisiana parish and municipality enforces the state’s Uniform Construction Code (R.S. 37:3737), adopted by the Louisiana Uniform Construction Code Commission: the 2021 International Codes with Louisiana amendments, in force since 1 January 2023, and the 2020 National Electrical Code, with the 2024 codes taking effect on 1 January 2027. A local government may set more stringent requirements only with the Commission’s approval, and the State Fire Marshal reviews plans for fire and life safety on all but one- and two-family dwellings. How the LSUCC works

Who handles permitting in New Orleans?

Safety and Permits handles plan review, building, electrical and mechanical permits, and inspections throughout the city. Plumbing permits are issued by the Sewerage and Water Board (S&WB) Plumbing Department through the One Stop, and only an Orleans Parish licensed master plumber registered with S&WB may apply for one. Because the city and parish are one government there is no separate parish permit, but the historic review bodies are separate authorities, and the State Fire Marshal reviews plans for life safety on buildings other than one- and two-family dwellings.

The One Stop App handles application, document upload and fee payment. Inspections are requested by email to inspections@nola.gov once the permit is issued, and the inspection status is then shown in the One Stop App; plumbing inspections are requested through the Sewerage and Water Board. Because so many New Orleans projects carry a design review approval, a flood determination and a state fire review alongside the building submittal, keeping those approvals attached to the correct record matters more here than in a simpler jurisdiction.

Much of the city's building stock is old, which makes the existing building provisions of the LSUCC the operative document on a large share of projects. How much of a structure must be brought to current requirements, what a change of occupancy triggers, and how structural adequacy is demonstrated in a building with no original drawings are all questions worth settling with the department before design develops.

In 2025, building permits issued in New Orleans authorized 882 new privately owned housing units, 210 of them single-family homes, according to the U.S. Census Bureau Building Permits Survey.

Louisiana’s counties are parishes, governed by a police jury or a home rule charter government, and some large communities, such as Metairie, have no city government and are permitted by the parish. The state sets the code and licenses contractors; the local authority sets fees, submittal requirements, review times, inspections, zoning, floodplain administration and local registration. What the state and the parish each decide

Permit types

Residential permits

Residential work is dominated by renovation, restoration and elevation of historic housing, together with infill construction and post-storm rebuilding. The three governing questions are the flood zone and required elevation, the historic district status, and the existing-building compliance path. All three should be settled before design, and on an elevation project the first two have to be reconciled with each other.

Commercial permits

Commercial work spans hospitality and tourism, downtown and warehouse district redevelopment, medical and institutional construction, and port-related activity. Adaptive reuse of historic commercial buildings is a defining category, bringing change of occupancy, life-safety retrofit, accessibility and structural verification together in buildings never designed for their new use. Commercial plans are reviewed by the city's Plan Review Division, and the State Fire Marshal reviews them for life safety.

Flood elevation and wind design decide most Louisiana projects: in a FEMA Special Flood Hazard Area, base flood elevation, flood-resistant construction and the substantial-improvement rules apply; the state code’s wind provisions include wind-borne debris requirements in wind-borne debris regions; and elevation certificates are permit documents that can delay the certificate of occupancy.

New Orleans permit costs and fees

The New Orleans building permit fee is $60 plus $5 per $1,000 of the value of the work. Where plans are required, a plan review fee of $1 per $1,000 is added (minimum $60). Electrical and mechanical permits are charged separately, and the Sewerage and Water Board charges its own fee for plumbing permits. Starting work before the permit is issued carries a penalty of twice the building permit fee. Design review and flood-related approvals carry their own processes and, where applicable, their own fees.

Fee schedules are revised on each jurisdiction’s own cycle, so ask New Orleans for the schedule in force on your filing date, and ask separately about plan review, trade, re-inspection and revision charges. How Louisiana permit fees work

Trade permits and who may pull them

The Louisiana State Licensing Board for Contractors requires a commercial licence for projects of $50,000 or more, a residential licence for a new house or duplex of $50,000 or more, a home improvement licence for residential improvement work of $7,500 to under $50,000, and a licence for electrical, mechanical and plumbing work of $10,000 or more. Since 1 January 2026 residential roofing of $7,500 or more needs a roofing or residential licence, and plumbers are also licensed by the State Plumbing Board of Louisiana until its duties pass to the contractor board on 1 January 2027.

How to apply for a New Orleans building permit

In Louisiana the approvals that sit ahead of the building permit, such as historic or design review, zoning and subdivision, most often decide timing. Before filing, ask New Orleans for the current review turnaround, which bodies review commercial plans (the State Fire Marshal and the local authority or its contracted reviewer), and which approvals must be in hand first.

Inspections in New Orleans

Standard checkpoints include foundation, framing, rough-in electrical, plumbing and mechanical, insulation and final, with a certificate of occupancy required before legal occupancy or use. Elevated construction adds elevation verification, and historic work may add design compliance checks.

On renovation of old housing stock the risk is concealment: structural repair, rated assemblies and elevation work must be observable when the inspector attends. Sequence deliberately, and keep elevation certification current rather than producing it at the end.

Do not cover work before the required inspection has been approved. Keep the issued permit, the approved plans, energy documentation, product listings, special-inspection reports and your correction responses available on site.

Plan framing, sheathing and roofing inspections so that wind-resistive connections and opening protection can be seen before they are covered, have elevation verified at the required stages, and keep product approvals and elevation documentation on site. Inspections in Louisiana

New Orleans permit search and official resources

Permit records sit with the authority that issued them. In Louisiana that is usually straightforward, because the LSUCC has applied statewide since 2023 and the permitting authority for a given parcel is generally stable — but records predating the statewide code, or predating a municipal incorporation or annexation, may sit elsewhere. If you are buying, refinancing or renovating, ask the Department of Safety and Permits what it holds for the parcel and whether any permit was closed without a final inspection.

On flood-exposed property the record question is sharper than usual. Prior elevation certificates, floodplain determinations and any history of substantial damage or improvement all bear on what a new project will be required to do, and they are worth obtaining before design rather than during review.

These are the primary sources behind this guide. Codes, fee schedules and portal procedures change, and in Louisiana a jurisdiction’s own published packet can lag a code change by months — the adopted ordinance governs, not an un-updated handout. Confirm the position for your filing date.

Frequently asked questions

Do I need historic approval before my building permit?

In the local historic districts, yes. The building permit is not issued until HDLC or Vieux Carre Commission design approval is granted. The HDLC process starts when you apply for the building permit, so establish designation before exterior work is designed.

Is there a separate Orleans Parish permit?

No. New Orleans is coextensive with Orleans Parish under a consolidated city-parish government, so there is no separate parish permit. Plumbing permits, however, are issued by the Sewerage and Water Board rather than Safety and Permits.

What governs elevating a historic house?

Both the flood requirements and the design review bodies. Elevation changes the street presentation that design review exists to protect, so the two have to be reconciled at design stage rather than sequentially.

Can this jurisdiction impose stricter requirements than the state code?

Only with the state’s approval. Parishes and municipalities must enforce only the Uniform Construction Code (R.S. 37:3737), but a local government that finds the state minimum standards do not meet its needs may set more stringent requirements with the approval of the Louisiana Uniform Construction Code Commission (R.S. 37:3748). What does vary locally is zoning, flood and elevation requirements, historic review, fees, portals and inspection scheduling.

Who reviews my commercial drawings?

On commercial work, usually both. The Office of State Fire Marshal reviews plans for fire and life safety on every building except one- and two-family dwellings (R.S. 40:1574), and the local authority, or a reviewer it contracts with, reviews against the Uniform Construction Code. Establish both routes before you submit.

What licence does my contractor need?

A Louisiana State Licensing Board for Contractors credential in the right classification. A commercial licence is required at $50,000 or more, a residential licence for a new house or duplex of $50,000 or more, and a home improvement licence for residential improvement work of $7,500 to under $50,000. Electrical, mechanical and plumbing contractors need a licence for work of $10,000 or more, residential or commercial (R.S. 37:2150.1).

Simplify New Orleans permitting with Alliance Permitting

New Orleans is a city where the building code is the predictable part. Historic design approval that must precede the permit, flood elevation set by the site, and an existing-building compliance path in very old stock are the three things that decide a project here.

Trusted by leading builders, developers, and national contractors — 21+ years of filing in the jurisdictions we write about.

Contractors and builders choose Alliance for New Orleans because the work is done by people who have stood at the counter:

• We establish historic district status before exterior work is drawn.
• We fix flood zone and base flood elevation before design begins.
• We reconcile elevation requirements with design review rather than sequencing them.
• We agree the existing-building compliance path with the department early.
• We keep design, flood and permit records aligned in the One Stop App.

Alliance Permitting is a permit documentation and submission company in Louisiana. We prepare your paperwork, file it correctly and coordinate with the building department through issuance. We are not a contractor and we do not perform licensed plan review or inspections; that work stays with your licensed team and the jurisdiction.
