Kenner, Louisiana Building Permit Guide

Building permits inside the City of Kenner are issued by the Inspection and Code Enforcement Department at 1926 18th Street. Kenner sits at the western end of Jefferson Parish on the shore of Lake Pontchartrain, and it illustrates the parish's central jurisdictional lesson from the opposite side: Kenner is incorporated and permits its own limits, while neighbouring Metairie is not and does not.

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 inside the City of Kenner limits. Neighbouring Metairie and other unincorporated areas are permitted by Jefferson Parish.

What requires a building permit in Kenner?

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

Kenner enforces the statewide LSUCC and cannot vary it, as does Jefferson Parish next door. The technical requirements do not change as you cross the city line. Fees, the submittal process, inspection scheduling, zoning and the flood and elevation layer for the specific parcel all do.

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.

Who handles permitting in Kenner?

The Inspection and Code Enforcement Department handles permitting, plan review and inspections inside the city limits, and issues the city’s tradesman licences for electricians, plumbers and mechanical contractors. Its Permitting Office is at 1926 18th Street (504-468-4062, Option 1), open 8:30am to 4:30pm Monday to Friday. Jefferson Parish permits the surrounding unincorporated territory, including Metairie.

Much of Kenner sits low and close to Lake Pontchartrain behind the levee and drainage system, so flood zone status, base flood elevation and drainage are routine rather than exceptional considerations. Establish the flood position for the parcel from the effective mapping before design, and on renovation test the scope against the substantial improvement threshold.

The city's housing stock is largely post-war suburban, which makes renovation, addition and system replacement a large share of the residential caseload. On that work the existing building provisions determine how far a project must go, and it is worth agreeing the compliance path with the department before design develops.

In 2025, building permits issued in Kenner authorized 28 new privately owned housing units, 24 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, addition and replacement in an established suburban stock, with infill construction and post-storm repair alongside. Flood elevation and the substantial improvement threshold are the recurring constraints, and the existing-building compliance path governs renovation scope.

Commercial permits

Commercial development includes airport-related hospitality, logistics and services, retail and office space along the corridors, and lakefront and civic development. Taller commercial projects near the airport may need FAA airspace review. The city reviews commercial plans against the building code, 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.

Kenner permit costs and fees

Kenner permit fees are valuation-based against the city's adopted schedule, with plan review and separate trade fees. Jefferson Parish maintains a separate schedule.

Fee schedules are revised on each jurisdiction’s own cycle, so ask Kenner 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 Kenner 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 Kenner 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 Kenner

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.

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

Kenner 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 Kenner Inspection and Code Enforcement Department 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

Does Jefferson Parish issue permits in Kenner?

No. Kenner is incorporated and permits its own limits. The parish permits the surrounding unincorporated areas, including Metairie, which has no city government.

How do I tell Kenner from Metairie?

By the parcel, not the street. The development is continuous across the boundary with no visible change, and the two file in completely different places.

Does the airport affect my project?

It can. Structures and cranes near Louis Armstrong New Orleans International Airport may need notice to the FAA and an airspace determination under 14 CFR Part 77. That is a federal process, separate from the city permit, so ask the department whether any local zoning limit also applies to your parcel.

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 Kenner permitting with Alliance Permitting

Kenner's defining permitting fact is the boundary it shares with Metairie, an unincorporated community more than twice its size (143,507 people in the 2020 Census, against Kenner's 65,136 in 2025). The error costs a full cycle and is entirely avoidable, and airport airspace limits are the second thing people discover too late.

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

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

• We confirm Kenner versus unincorporated Metairie on the parcel.
• We check airport height and airspace constraints at the site stage.
• We establish flood zone and elevation before design.
• We test renovation scope against the substantial improvement threshold.
• We agree the existing-building compliance path in an older suburban stock.

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.

This guide is provided by Alliance Permitting for general information about Kenner permitting. Requirements, fees, and procedures change; confirm details with the permitting authority before relying on them.
