Screened Porch vs Sunroom Cost in Austin, TX (2026 Pricing)

How much does a screened porch or sunroom cost in Austin in 2026?

There are four levels of enclosure, and each one steps up in price. Screening in an existing covered patio of about 12x16 (192 square feet) typically costs $8,000 to $14,000. Building a new screened porch with its own roof and structure, about 14x16 (224 square feet), runs $22,000 to $35,000.

A three-season sunroom of about 12x14 (168 square feet) runs $30,000 to $48,000. A four-season insulated sunroom of about 14x16 (224 square feet) runs $55,000 to $90,000, and large ones go into six figures.

All of those are complete project prices, including structure, screens or windows, electrical, permits, and cleanup. We quote every project at a fixed price, so there are no allowances that grow after construction starts.

What is the difference between a screened porch and a sunroom?

A screened porch is an outdoor room: a solid roof with screen walls instead of glass. You get the breeze and keep the bugs out, but the temperature is whatever it is outside. With a ceiling fan, a screened porch is often the most comfortable option in a Texas summer because air moves through it.

A three-season sunroom replaces the screens with sliding vinyl windows, usually over knee walls. It keeps out rain, dust, and pollen as well as bugs, and it is comfortable roughly nine months of the year. Closed up without conditioning, it gets hot in July, especially facing west.

A four-season sunroom adds insulated walls and roof, dual-pane low-E glass, and heating and cooling, usually a mini-split. It is as comfortable as your living room in August and January, and it costs like the room addition it is.

How much does a screened porch or sunroom cost per square foot?

Screening runs about $30 to $55 per square foot installed. On a 12x16 covered patio that already has a sound roof, 192 square feet times $30 to $55 is roughly $5,800 to $10,600, and the finished conversion typically lands at $8,000 to $14,000 once the door, kick plates, and any reinforcement are in.

A new screened porch costs more because you are building the roof, posts, and footings too, which is why a 14x16 new porch runs $22,000 to $35,000. Sunrooms price at a higher rate: about $120 to $220 per square foot for a three-season room and $200 to $350 per square foot for a four-season room. A 12x14 three-season room is 168 square feet, so the room itself works out to about $20,000 to $37,000, and finished projects typically land at $30,000 to $48,000 with the foundation, electrical, trim, and permits. A 14x16 four-season room works out to about $45,000 to $78,000 for the room, and $55,000 to $90,000 as a finished project with conditioning and energy code work.

Screened porch vs three-season vs four-season: which is right for you?

Choose a screened porch if you mainly want bug-free evenings from spring through fall and you like the feel of open air. It is the best value, and it is where most families start. Central Texas has a long mosquito season, roughly February through November in a warm year, so screens pay off for most of the calendar.

Choose a three-season sunroom if you want protection from rain, pollen, and wind, and you are fine with the room being too hot in the peak of summer or cool on the coldest winter days. It costs about double a new screened porch.

Choose a four-season sunroom if you want real, year-round square footage for an office, a playroom, or a breakfast room. It is the most expensive option and the only one that stays comfortable in a 105 degree August. Many clients start with screens and upgrade to windows later, and we can frame the porch for that from the beginning.

What drives the price of a screened porch or sunroom?

The biggest factor is the level of enclosure, followed by size. After that, the existing structure matters. If you already have a solid covered patio or deck, converting it costs far less than building new, but only if the posts, beams, footings, and ledger can carry screen walls, a door, and the added wind load. We inspect all of that before quoting, and if reinforcement is needed you know before you sign.

Screen and glazing choices also move the number. Standard fiberglass screen is the most affordable. Pet-resistant mesh, solar screen for west-facing walls, and fine 20x20 mesh for no-see-ums near water or ranch land each add cost. Motorized retractable screens run $3,500 to $7,000 per opening installed and work well on large openings or outdoor kitchens.

For sunrooms, insulation, window quality, and heating and cooling are the big line items. Roof tie-in is another. We frame and flash the new roof into your existing roofline and match siding and trim so the room looks original to the house. Electrical for fans, lights, and outlets rounds it out.

Is a sunroom usable in an Austin summer?

It depends on the type. A four-season sunroom with insulated glass and a mini-split stays comfortable all summer. A three-season room with the windows open behaves like a screened porch, but closed up without conditioning it heats up fast, especially on a west or south exposure.

That is why orientation matters so much here. We look at your sun exposure during the consultation and plan roof insulation, low-E glass, shade, and ventilation around it. Skipping roof insulation on a west-facing room is the most common mistake we see, and it is much cheaper to do during construction than after.

Do you need a permit for a screened porch or sunroom in Austin?

Yes. Anything enclosed and attached to your home needs a building permit in every city we serve, from Austin to Georgetown to Liberty Hill. A screened porch is usually a straightforward structural permit. A conditioned sunroom also goes through energy code review, so insulation values and window specs get checked.

Many HOAs, including Sun City in Georgetown and neighborhoods across Cedar Park, Round Rock, and Leander, require architectural approval on top of the permit. Plan on two to six weeks for permits and HOA review, with conditioned sunrooms at the longer end. Construction then takes one to two weeks for a screen-in, three to five weeks for a new screened porch, and four to eight weeks for a sunroom. We handle all permits and HOA paperwork, and the cost is inside your fixed quote.

How do you get an accurate screened porch or sunroom quote?

Start by deciding how you want to use the room: bug protection only, rain and pollen protection, or year-round comfort. That one answer sets most of the budget. Then have the existing structure evaluated, because whether your current patio cover can be reused is the biggest swing in a conversion price.
