Screened porches are the fastest-growing thing people call us about, and the conversation almost always starts the same way: someone says they want a sunroom, and what they actually want is a screened porch.
They are not the same build, they are not the same money, and in Central Texas they are not the same value. Here is the straight version.
The short answer on cost
| What you are building | Typical range, installed |
|---|---|
| Screening in an existing covered patio | $12,000 to $22,000 |
| New structure plus screen enclosure | $22,000 to $38,000 |
| Same, with a deck built underneath | $30,000 to $48,000 |
| Glazed, insulated sunroom (true addition) | $45,000 to $90,000+ |
That last row is the one that ends most sunroom conversations, and it should. A sunroom is an addition. It carries foundation work, insulation, HVAC, and addition-level permitting, and it is priced accordingly.
Screened porch or sunroom: the actual difference
A screened porch
A roofed structure with screen panels where walls would be. It is not conditioned space. No insulation, no vapour barrier, no HVAC, no ductwork. Air moves straight through it.
What you get is shade, rain cover, and the thing Austin homeowners actually want, which is sitting outside at dusk in June without being eaten alive. What you do not get is a usable room during a February cold snap or a 105-degree August afternoon.
A sunroom
Glazed, insulated, and usually tied into the home's heating and cooling. It is a room of the house that happens to have a lot of glass. It appears in the square footage, it needs a proper foundation, and it goes through permitting as an addition.
A sunroom is genuinely lovely. It is also two to three times the money, and the extra you are paying for buys you the part of the year Austin spends indoors anyway.
Why we steer most Austin homeowners to the porch
This is a climate argument more than a money argument.
Central Texas gives you long, generous shoulder seasons. March through May and late September through December are the months people actually want to be outside, and a screened porch is perfect in every one of them. It handles the two things that otherwise ruin outdoor time here, which are direct sun and mosquitoes.
The months a sunroom adds, deep summer and the handful of genuinely cold weeks, are months you would mostly spend in the house regardless. You would be paying roughly double to unlock the part of the calendar you are least likely to use.
There is a real exception. If you want a year-round office, a studio, a plant room, or additional square footage that counts on an appraisal, then a sunroom is the right build and a porch will disappoint you. Be honest with yourself about which one you are picturing.
What drives screened porch cost up or down
1. Whether you already have a roof
This is the biggest single variable. If you have an existing covered patio in sound condition, screening it in is comparatively simple and lands at the bottom of the range. If we are building the structure and the enclosure together, you are paying for posts, beams, rafters, roofing and flashing before a single screen panel goes up.
Not every existing cover can be screened. The posts and beams have to be sized to carry screen framing, the slab or deck has to be reasonably level, and the roof has to already shed water away from the house rather than into it.
2. The ceiling
Bare rafters overhead read as a carport. A finished tongue-and-groove pine or cedar ceiling reads as a room, and it is the upgrade that changes how the space feels more than anything else you can do. It runs $12 to $25 per square foot installed, so a 14x16 ceiling adds $2,700 to $5,600.
If your budget is tight, this is the one upgrade we would tell you to keep and find savings elsewhere.
3. The floor
If you are screening in a concrete slab, the floor is already handled and you can stain or leave it. If you want a wood floor, you are building a deck underneath, which is a real project of its own at $10,500 to $26,000 depending on size and height.
4. Screen type
Standard fibreglass mesh is fine for most homes and is what we install by default. Pet-resistant mesh is significantly heavier and worth it if you have dogs, because standard screen does not survive a determined dog. Solar screen cuts heat noticeably on a west-facing porch, at the cost of some visibility and a slightly darker feel.
5. Doors
You need at least one, and the cheap aluminium ones sag inside two years. A properly framed wood screen door with real hardware costs more up front and does not become the thing you apologise for.
6. Electrical
A ceiling fan is close to mandatory on a screened porch in Texas, because screen cuts airflow more than people expect. Fan wiring and install runs $400 to $900 if there is an existing run nearby, $800 to $1,800 if we have to trench new wiring. Outdoor-rated outlets run $200 to $450 per location.

Screening in a cover that was never designed for it. Someone adds screen framing to a light patio cover, and a year later the posts have racked and the screen panels are out of square. The structure has to be right first.
Skipping the fan. Screen reduces airflow. A porch with no fan is noticeably hotter than the open patio it replaced, and people are always surprised by that.
Cheap door hardware. A screen door gets used thousands of times a year. Spend the extra on hinges and a closer.
Not planning for leaves and pollen. A screened porch under oaks collects a remarkable amount of debris on the screen. It is not a reason to skip the build, just a reason to plan on hosing it down a couple of times a year.
Permits and HOA
An attached screened porch is a structure, so inside most Austin-area city limits it generally needs a permit and often an engineer's stamp, especially where it ties into the existing roofline. Screening in an existing covered patio is sometimes simpler, but do not assume. We pull permits as part of the project rather than leaving it with you.
Separately, most Austin-area subdivisions have an active HOA with architectural review, and a screened porch changes the exterior of the house, so it is going to need approval. Review commonly takes two to four weeks. We prepare and submit the packet with drawings and material specs as part of every project.
If you want to be sitting on a finished porch by spring, start the conversation in winter. The review clock is the part nobody plans for.
How long the build takes
Screening in an existing covered patio is usually a few days to a week on site. Building the structure and the enclosure together is commonly two to four weeks. Add a deck underneath and you are at the longer end of that.
Almost none of that is the screen. It is the framing, the roof and the ceiling.
What we would build on most Austin lots
If it were our house: a solid-roof structure with a finished tongue-and-groove pine ceiling, a stained wood or stained concrete floor, standard screen unless there are dogs, one properly built wood screen door, a ceiling fan, and two outdoor outlets.
That is a genuine three-season room for a fraction of what an addition costs, and it is the build people tell us years later they use more than any other part of the house.
Screened porch questions from Austin homeowners
How much does a screened porch cost in Austin?
A screened porch built onto an existing covered patio typically runs $12,000 to $22,000 in the Austin area. Building the structure and the screen enclosure together, which is the more common job, runs $22,000 to $38,000 depending on size, ceiling finish and whether there is a deck underneath.
What is the difference between a screened porch and a sunroom?
A screened porch has screen panels instead of walls. It is not conditioned space, so it needs no insulation, no HVAC and no vapour barrier. A sunroom is glazed, insulated and usually climate controlled, which makes it a full addition with addition-level permitting, foundation requirements and cost.
Is a sunroom worth it in Austin?
For most Austin homes, no. A sunroom costs roughly two to three times a comparable screened porch and its main advantage is use in January and August, which is a small part of the year here. Central Texas has long, pleasant shoulder seasons, which is exactly when a screened porch shines.
Do I need a permit for a screened porch in Austin?
Usually yes. A screened porch attached to the house is a structure, so it generally needs a permit and often an engineer's stamp, particularly where it ties into the roofline. Screening in an existing covered patio is sometimes simpler. We pull permits as part of the project.
Can you screen in an existing covered patio?
Often yes, and it is the cheapest route to a screened porch by a wide margin. The deciding factors are whether the existing posts and beams are sized to carry screen framing, whether the slab or deck is level enough, and whether the roof already sheds water away properly.
What screen should I use in Central Texas?
Standard fibreglass is fine for most homes. Upgrade to a heavier pet-resistant mesh if you have dogs or cats, because standard screen will not survive a determined dog. Solar screen cuts heat noticeably on a west-facing porch at the cost of some visibility.
How long does a screened porch take to build?
Screening an existing covered patio is usually a few days to a week. Building the structure and the screen enclosure together is commonly two to four weeks on site. The longer part is often ahead of that, since HOA architectural review typically takes two to four weeks.
