Most homeowners in the New Orleans metro who want to enclose a patio are after the same two things: evenings without mosquitoes and an outdoor room that still works when an afternoon storm rolls through. There’s more than one way to enclose a patio in New Orleans or on either side of the lake, and each option trades airflow against weather protection in its own way. The paperwork changes too, and it turns on what you build and where your house sits.
This guide compares the main ways to enclose a patio and the local permit rules to check first. It’s general information, not a code review of your address, so confirm the details with your permit office before work starts.
Key takeaways
- A screen room blocks bugs but keeps the breeze, while a glass enclosure keeps the weather out as well.
- Motorized retractable screens roll down on demand, so the patio can stay open the rest of the time.
- Louisiana’s statewide code uses the 2021 International Residential Code for houses, and the state lists January 1, 2027 as the effective date for the 2024 editions.
- That residential code sorts sunrooms into 5 categories, from a screened, unconditioned room up to a heated or cooled room that’s open to the house and counted as habitable.
- New Orleans says roofs over otherwise unenclosed porches aren’t exempt from permitting, and Jefferson Parish requires a building permit for carports of any size.
- In New Orleans historic districts, the HDLC treats a screened-in porch as an enclosed porch.
What are the ways to enclose a patio in New Orleans?
Most enclosure projects in the metro land in one of three groups. The right one depends on when you use the space and how much weather you want to keep out.
Screen rooms
A screen room wraps a covered patio or a new frame in insect screening. You keep the breeze and the sound of rain on the roof, and the mosquitoes stay on the far side of the mesh. We build ours on engineered, wind-rated frames and covers, then tension each screen panel on its own, so a storm or a dog that tears one panel means replacing that panel instead of rescreening a whole wall. If your patio already has a sound roof, screening it is often the quickest route to an enclosed space. You can see how that works on our screen rooms and glass enclosures page.
Mesh choice matters too. Finer weaves are made for the tiny biters that show up near water at dusk, and our guide on how to choose the right screen material goes deeper on that decision.
Glass enclosures
When you want the bugs out and the weather out too, glass picks up where screens stop. We install glazing systems for patios and porches, including sliding glass panels and folding systems that open a whole wall. Guillotine-style units are another choice, with panels that move vertically into the frame. Insulated and laminated glass options can make the room more comfortable in summer heat and quieter during a downpour. You can also combine the two, with glass on the weather side and screens where you want the breeze.
Motorized retractable screens
Motorized screens roll down from a slim housing into side tracks and disappear when you don’t need them. They fit a covered patio you want open in the morning and sealed at dusk, and they mount cleanly to an existing cover. We compared the two approaches in motorized patio screens vs. a full screen room, and our awnings and motorized shades page covers exterior shades that work the same way against glare.
How does the building code tell a screen room from a sunroom?
Louisiana builds to one statewide code. The Louisiana State Uniform Construction Code rule adopts the 2021 International Residential Code, minus its administrative and electrical parts, and the state’s code body lists January 1, 2027 as the date the 2024 editions take effect. If your project straddles that date, ask your designer which edition applies to your permit.
Inside the 2021 residential code, Section R301.2.1.1.1 requires sunrooms to comply with the AAMA/NPEA/NSA 2100 standard and to be identified by category in the construction documents. The categories run from a simple screened room to a fully conditioned one:
- Category I: walls that are open or enclosed with insect screening or thin plastic film. The code calls this space nonhabitable and unconditioned.
- Categories II and III: enclosed walls with glass or plastic in the openings, still nonhabitable and unconditioned. Category III adds requirements for air infiltration and water penetration resistance.
- Category IV: enclosed walls, heated or cooled by a separate system and thermally isolated from the house. The space is conditioned but still nonhabitable.
- Category V: enclosed walls, designed to be heated or cooled and open to the main structure. The code calls this space habitable and conditioned.
Put simply, the more your enclosure behaves like a room of the house, the more it’s designed like one. A screened patio you never cool is a different project from a glassed room with its own air conditioning and a wide opening into the kitchen. Decide which one you actually want before you ask for a design, because that choice shapes the frame and the drawings you submit.
Local permit rules for enclosing a patio across the New Orleans metro
Every permit office in the metro enforces the same state code, but each one publishes its own guidance. Our patio cover permit guide covers the general picture. Here’s what matters most for enclosures.
New Orleans
The city’s guide to building permits says “roofs over otherwise unenclosed porches along with their framing is not exempt from permitting,” and it calls for plans stamped by a Louisiana licensed architect or civil engineer for new construction and additions. Freestanding structures go through the city’s accessory structure permit, which lists gazebos and picnic pavilions among its examples.
Historic districts add another layer. In the HDLC’s design guidelines, “a screened-in porch is considered an enclosed porch,” so screening a porch that’s visible from the street in a local historic district becomes a historic review question as well as a permit question. French Quarter properties answer to the Vieux Carré Commission instead. City homeowners can see how we approach these projects on our New Orleans screen rooms page.
Jefferson Parish
Jefferson Parish’s permit guidance says “no work may be done before a permit is obtained,” and it lists carports of any size among the structures that require a building permit. It doesn’t name screen rooms or glass enclosures, so ask the parish how it classifies your project before materials are ordered. Kenner is its own city, and its Inspection and Code Enforcement Department reviews and issues building permits for structures inside city limits, so Kenner addresses start there. For Metairie, our Metairie screen rooms page shows the options we offer there.
St. Tammany Parish and the Northshore
St. Tammany Parish’s permit office has required an engineered wind design since January 1, 2025 for several kinds of work, including additions over 500 square feet and accessory buildings over 1,000 square feet. The parish memo says the wind design has to be specific to the structure and stamped by a Louisiana licensed architect or engineer. A large glassed room tied into the house could cross that addition threshold. If your address sits inside Covington, Mandeville, Madisonville, or Abita Springs, check with that municipality first, since town permit offices can set their own requirements. Northshore homeowners can start with our Mandeville screen rooms page.
What drives the cost of enclosing a patio?
We don’t publish one price for enclosures, because a handful of site conditions move the number more than anything else. Here’s what we look at during a walkthrough before writing an estimate:
- The roof you start with. Screening a sound, existing cover is a smaller job than building a new cover and enclosure together.
- Screens or glass. Glazing systems, especially with insulated or laminated glass, add material and install time compared with tensioned screen panels.
- Size and openings. Longer walls and extra doors add panels and framing.
- Motorization. Motorized screens or shades add motors and wiring.
- Engineering and review. Stamped drawings and permit or historic review steps add time, especially for larger or conditioned rooms.
- Slab and drainage. A cracked or low slab, or a spot where water sits after a storm, needs attention before anything gets enclosed.
Every estimate we give is written, with the full scope spelled out. If the enclosure starts with a new roof, our patio covers page explains the insulated and aluminum options underneath it.
Planning an enclosure for storm season and humidity
The Atlantic hurricane season runs from June 1 to November 30, according to the National Hurricane Center, and an enclosure here has to be planned around it. Ask how the frame and cover are designed for wind at your address, and ask what the manufacturer expects you to do with operable glass panels or retractable screens before a storm. Our hurricane season patio prep guide covers the rest of the checklist.
Humidity is the other half of the job. A screen room breathes, so it dries out after a summer shower. A closed glass room can get hot fast on a July afternoon without ventilation or cooling, and cooling it changes which sunroom category it falls into. Think about how you’ll keep air moving before you pick glass for every side.
Frequently asked questions
Do I need a permit to enclose a patio in New Orleans?
Check before you build. The city’s building permit guide says roofs over otherwise unenclosed porches aren’t exempt from permitting, and it requires stamped plans for new construction and additions. Confirm the details for your project with the Department of Safety and Permits. If your house is in a local historic district, check that too.
Is a glass patio enclosure the same as a sunroom?
Under the 2021 residential code, a sunroom falls into one of 5 categories. A glassed patio that stays unconditioned fits one of the nonhabitable categories, while a room designed to be heated or cooled and open to the main house is Category V, which the code treats as habitable. The category gets identified in the construction documents.
Can I screen a porch in a New Orleans historic district?
It depends on your district and what’s visible from the street. The HDLC’s guidelines treat a screened-in porch as an enclosed porch and say the HDLC does not permit enclosing a porch visible from the public right-of-way. Check with HDLC staff before planning any street-facing project.
Should I choose screens or glass for a Metairie patio?
That comes down to how you use the space. Screens keep the airflow, while glass keeps rain out and can be part of a conditioned room. You can also mix them, with glass on the side that takes the weather and screens where the breeze comes through.
