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 code edition that actually governs a filing here and when it changed, the statutory conditions on permit issuance that sit outside the building code, what permits cost and who may pull them, and how inspections are booked.
This guide covers work inside the City of Kenner limits. Neighbouring Metairie and other unincorporated areas are permitted by Jefferson Parish.
Kenner and Metairie sit side by side and file in completely different places. Kenner is an incorporated city with its own building department; Metairie has no city government at all and is permitted directly by Jefferson Parish. The built environment across that boundary is continuous suburban development with no visible change. This is the single most common jurisdictional error in the parish, and it is settled by checking the parcel rather than by looking at the street.
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.
Permit required
- New residential and commercial construction, additions, conversions and tenant improvements
- Structural and load-bearing alterations, foundations, decks, porches and garages
- Electrical service changes, panel work, new circuits, solar and EV charging equipment
- Plumbing alterations, repipes, water heaters, gas piping and sewer connections
- HVAC installations, change-outs, ductwork and venting
- Re-roofing, siding, windows, pools, signs, demolition and change of occupancy or use
Typically exempt
- Painting, wallpapering, tiling, carpeting and cabinet installation
- Countertop replacement and comparable finish work
- Minor repairs replacing existing materials in kind with no structural or system change
- Small detached accessory structures below the local size threshold, where zoning allows
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.
Louisiana runs one of the most uniform construction-code regimes in the country, and understanding why explains almost everything about how permitting works here. After Hurricane Katrina the Legislature created the Louisiana State Uniform Construction Code under La. R.S. 40:1730.21 et seq., administered by the Louisiana State Uniform Construction Code Council within the Office of State Fire Marshal. The LSUCC adopts the 2021 International Codes — Building, Residential, Existing Building, Plumbing, Mechanical, Fuel Gas and Energy Conservation — with Louisiana amendments, effective 1 January 2023, together with the National Electrical Code.
The decisive provision is that no parish or municipality may adopt construction codes more stringent or less stringent than the LSUCC. Local government administers permitting and inspection; it does not set the technical standard. That means the code you design to in Kenner is the code you design to across Louisiana, and a plan set that satisfies the LSUCC is technically sufficient statewide. What still varies locally — and varies a great deal — is zoning, flood and elevation requirements, historic review, fee schedules, portals, submittal expectations and inspection scheduling.
That is a genuinely useful thing to know, because it tells you where to spend your effort. In Louisiana the technical review is predictable. The local layer is where projects actually get held up.
The State Fire Marshal also carries its own life-safety review responsibilities on many occupancy types, so on commercial and institutional work it is common to be dealing with the state and the local authority in parallel rather than sequentially. Ask early which reviews run concurrently.
Who handles permitting in Kenner?
The Inspection and Code Enforcement Department handles permitting, plan review and inspections inside the city limits. 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.
Louisiana calls its counties parishes, and the difference is more than vocabulary. Parish government takes several forms — a police jury, a parish council, or a consolidated city-parish government — and which form applies affects who administers permitting and how the department sits within the wider government. Louisiana also has an unusually high number of large communities with no municipal government of their own, which are permitted by the parish rather than by a city.
What the state decides, and what Kenner decides
Because Louisiana splits these questions unusually cleanly, it is worth setting out plainly which body answers what — it saves asking the wrong office and getting a confident wrong answer.
The state decides the technical standard. The construction code itself, its edition, its Louisiana amendments and the referenced standards all come from the LSUCC through the Council and the Office of State Fire Marshal. No local authority may add to it or subtract from it. The state also performs commercial plan review wherever the local authority does not, and holds its own life-safety review responsibilities on many occupancy types. Contractor licensing is a state question too, through the contractor board and, on plumbing, the plumbing board.
Kenner decides almost everything else. Whether a permit is required for a particular scope, what the application must contain, the fee schedule, the portal, the review turnaround, inspection scheduling and sequencing, zoning and land use, subdivision and drainage requirements, floodplain administration and elevation documentation, historic and design review where it applies, and local contractor registration. That is a long list, and it is where the working life of a permit actually happens.
So the useful instinct in Louisiana is the reverse of the instinct in a home-rule state. Do not ask the local department what the code requires — that is settled statewide and portable. Ask them what they need from you, in what order, and by when.
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.
Flood, elevation and wind requirements
Flood, elevation and wind — the constraints that actually govern
Because the LSUCC removes technical variation between jurisdictions, the requirements that most often decide a Louisiana project are the ones layered on top of it: flood elevation, wind design and, in some cities, historic review. All three are established from the site rather than the code book, and none of them can be retrofitted into a finished design.
On flood, a parcel inside a FEMA Special Flood Hazard Area brings base flood elevation, flood-resistant construction and floodplain development requirements, and on renovation the substantial improvement and substantial damage thresholds can convert a repair project into a full-compliance one. Louisiana has more property in mapped flood hazard areas than almost any state, so this is the normal case rather than the exception. Establish the flood zone and base flood elevation for the specific parcel before design, and confirm the effective mapping rather than working from an older panel.
On wind, the LSUCC carries Louisiana’s wind design provisions including wind-borne-debris requirements in the coastal zone. Opening protection, cladding, roof covering and connection detailing follow from the design wind speed and exposure for the site. In the parishes rebuilt after recent hurricanes these provisions are enforced with particular attention, and a design imported from a lower-exposure region will not clear review.
Elevation certificates and flood documentation are permit documents in Louisiana, not afterthoughts. On elevated construction the department will expect elevation documentation at defined points in the build, and a certificate produced late — or produced against the wrong datum — holds the certificate of occupancy rather than merely annoying the file clerk. Agree with the department at the outset who provides what, and at which stage.
Why construction standards carry financial weight in Louisiana
Louisiana has one of the most difficult property insurance markets in the country, and that gives construction quality a commercial dimension it does not have everywhere. How a roof is attached, whether openings are protected, how a structure is elevated and what documentation exists to prove any of it can bear directly on whether a completed building is insurable and on what terms. Owners here are frequently more receptive to build-quality decisions than owners elsewhere, because the consequences show up in an annual premium rather than only in a storm.
The practical implication for a permitting file is documentation. Product approvals, roof attachment details, opening protection specifications, elevation certificates and inspection records are worth assembling properly and handing to the owner at completion, not just satisfying the inspector and discarding. Several strengthening standards and incentive arrangements operate in Louisiana; confirm the current position with the owner’s insurer or broker rather than assuming, because the requirements are specific and the paperwork has to match them exactly.
Commercial permits
Commercial development includes airport-related hospitality, logistics and services, retail and office space along the corridors, and lakefront and civic development. Airport-area height and airspace considerations apply to commercial projects in a way they do not elsewhere in the parish, and commercial plan review may be local or performed by the State Fire Marshal.
What varies locally, and what does not
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 component | How it works |
|---|---|
| Residential building permit | Valuation-based against the adopted city fee schedule |
| Commercial building permit | Valuation-based, varying by scope, occupancy and floor area |
| Plan review | Per the adopted fee schedule; State Fire Marshal review may apply on commercial work |
| Trade permits | Electrical, plumbing and mechanical permits are charged separately |
| Flood and elevation | Floodplain development review and elevation certification where applicable |
| Re-inspections and revisions | Additional fees apply for failed inspections, revisions and expired permits |
Fee schedules in Louisiana are set locally and revised on each jurisdiction’s own cycle, so a figure quoted from a neighbouring city, an older packet or a national estimator is not a reliable number here. Ask the department for the schedule in force on your filing date, and ask separately about plan review, trade, and any re-inspection or revision charges, which are frequently billed as distinct lines.

Trade permits and who may pull them
Trade permits are generally separate from the building permit and are issued to the licensed installer. Louisiana licenses contractors through a single consolidated board, with classifications and dollar thresholds that decide which credential a project needs. Local registration with the permitting department is commonly required on top of the state licence before a permit will issue.
Louisiana consolidates contractor licensing in a single agency — the Louisiana State Licensing Board for Contractors. One board, with classifications, rather than a scatter of trade boards. The thresholds are what matter at the permit counter.
- Commercial licence — required for projects of $50,000 or more, in the relevant classification: Building, Electrical, Mechanical, Plumbing or Specialty.
- Residential licence — required for new construction of one- to four-family dwellings over $75,000.
- Home Improvement Contractor registration — required for residential remodelling between $7,500 and $74,999.
- Electrical, mechanical and plumbing subcontractors — require a licence once their commercial work exceeds $10,000.
Plumbing carries a second layer: plumbers are also licensed by the Louisiana State Plumbing Board, separately from the contractor board. On plumbing scope, confirm both credentials rather than assuming one covers the other.
Alongside the state credential, most Louisiana permitting authorities require the contractor to be registered locally before a permit will issue, and many require proof of general liability insurance and workers compensation coverage with the application. These are administrative rather than technical requirements, and they are among the most common reasons a submittal is held at intake rather than at review — the drawings are fine, but the contractor record is incomplete.
On projects using multiple trade subcontractors, confirm early which trades will pull their own permits and whether each holds the classification the scope requires. In Louisiana the trade permit is issued to the licensed installer, so a general contractor cannot cover a subcontractor whose credential does not match the work.
Permit required
- Electrical service installations, panel upgrades, new circuits, solar PV and EV chargers
- New plumbing, repipes, water heater change-outs, backflow, gas and sewer connections
- HVAC installation and change-out, ductwork, venting and commercial kitchen exhaust
- Fire alarm, sprinkler and suppression systems on commercial work
Typically exempt
- Replacing a fixture, switch, receptacle or light with no alteration to wiring or piping
- Clearing a stoppage without replacing or rearranging concealed piping
- Filter, thermostat and routine component service
- Appliance repair that does not alter the gas, electrical or venting connection
How to apply for a Kenner building permit
The boundary is invisible on the ground and the authorities are different.
These sit in the land-use layer and are not waivable through the code.
These are set by the site, drive elevation and construction requirements, and cannot be retrofitted.
Low-lying stock makes this a live question.
The local authority or the State Fire Marshal, depending on the jurisdiction.
Classification and value thresholds decide which licence applies; roofing needs one at any value.
Denials, corrections and appeals
Design review, zoning and the approvals that come first
Because the LSUCC settles the technical question statewide, the approvals that most often decide timing in Louisiana are the ones that sit ahead of the building permit rather than inside it. Several Louisiana jurisdictions operate historic district or design review bodies whose approval is a prerequisite to issuance, not a parallel process, and a scheme that satisfies the construction code can still be refused on design grounds. Zoning, land use and subdivision approvals behave the same way.
The practical rule is to establish the full approval sequence at the start of a project and to ask the department explicitly which approvals must be in hand before the building permit application will be accepted, which run concurrently, and which follow. That single question resolves most of the scheduling uncertainty on a Louisiana project, and it costs one phone call.
Review, corrections and appeals
Because the technical standard is statewide, correction cycles in Louisiana are more often about completeness and about the local layer than about disputed code interpretation. The most common causes of a held submittal are missing flood or elevation documentation, an unresolved historic or design review approval, contractor licensing that does not match the scope, and drawings that are not sealed where the project requires it.
Ask the department three things before filing: what the current review turnaround is for your project type, whether commercial plan review is performed locally or by the State Fire Marshal, and what approvals must be in hand before the building permit rather than alongside it. In several Louisiana jurisdictions the answer to the third question includes a design review approval that people routinely assume runs in parallel.
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.
Two categories of work are concealed by the following trade if the sequence is wrong, and both matter more in Louisiana than in most states. Wind-resistive detailing — roof-to-wall and wall-to-foundation connections, strapping, sheathing attachment and opening protection — has to be observable when the inspector attends, which means framing, sheathing and roofing inspections need planning rather than calling when convenient. Elevation work has to be verified at defined points, and a certificate produced after the fact, or against the wrong datum, holds the certificate of occupancy.
Keep the approved plans, the current revision set, product approvals, elevation documentation and the correction history available on site. In a state where so much turns on flood and wind documentation, being able to show the inspector what is current is frequently the difference between an inspection that proceeds and one that is rescheduled.
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.
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.
The technical code is statewide; almost everything else is local. Confirm the current LSUCC edition and any state amendments with the Council or the Fire Marshal — the 2021 codes have applied since 1 January 2023 and later editions have been under review — and confirm fees, portals, submittal requirements, review turnaround and the flood and historic layers with the local department for your filing date. One call to each settles a question that otherwise costs a correction cycle.
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. Airport environs typically carry height limitations, noise considerations and airspace review that restrict what is buildable, and these sit in the zoning layer rather than the construction code.
Can this jurisdiction impose stricter requirements than the state code?
Not on the construction code. No parish or municipality may adopt codes more stringent or less stringent than the LSUCC. What does vary locally is zoning, flood and elevation requirements, historic review, fees, portals and inspection scheduling.
Who reviews my commercial drawings?
Either the local authority or the Office of State Fire Marshal. Where a parish or municipality does not provide commercial plan review, the OSFM performs it, so establish which body will review your set 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 and above, a residential licence for new one- to four-family dwellings over $75,000, and Home Improvement Contractor registration between $7,500 and $74,999. Electrical, mechanical and plumbing subcontractors need a licence once commercial work exceeds $10,000.
