Most Round Rock enclosure projects start with a covered patio that is already there. Screening it typically costs $8,000 to $14,000 for a 12x16, and it needs a City of Round Rock permit. The city's published fees are $200 for a covered patio and $300 with electrical or plumbing, with about 30 business days of review.
Screening the patio you already have
Plenty of Round Rock homes have a builder covered patio or a cover added later. Before we screen one, we check that the posts sit on real footings, not the slab edge, and that the beam can carry screen walls, a door, and the wind load an enclosed room picks up.
East Round Rock sits on clay. If an existing post has moved, the screen door will bind. We fix the footing first. On the west side, limestone is closer to the surface and posts are usually stable.
Check the roof too. Many builder covers in Round Rock are framed with light rafters and a shallow pitch. Adding a door header and screen walls is usually fine, but a cover that already sags needs a new beam before we enclose it.
West sun and sunroom comfort
Many Round Rock backyards face west. A three-season sunroom on that wall gets hot fast in summer with the windows closed. If you want glass, plan for an insulated roof, low-E windows, and ventilation, or step up to a four-season room with a mini-split at $200 to $350 per square foot installed.
If you want screens, solar screen on the west wall blocks much of the heat and glare while keeping airflow. A ceiling fan does the rest.
Round Rock rules that shape the room
Round Rock reviews to the 2024 IRC. No structure may encroach into easements or 5 ft side and rear setbacks, and accessory structures are limited to 15 ft in height. For an existing patio, those limits rarely change anything. For a new screened porch or sunroom, they set how far out and how tall you can go.
The published fees are $200 for a covered patio and $300 when electrical or plumbing is included; an enclosed room may be classified differently, so we confirm at submittal. We include the fee in your quote.
Creeks, ponds, and mosquitoes
Neighborhoods along Brushy Creek and near retention ponds get steady mosquito pressure. If your lot backs onto a drainage area, check the flood zone before planning new footings. We build the room tight at the base, door, and roofline, which is where bugs get in.
Timing matters too. With about 30 business days of city review, a screen room you want done before peak mosquito season should be designed in winter. Construction on a screen-in typically takes 1 to 2 weeks once the permit is issued.
We Know Round Rock Backyards
Round Rock is Williamson County's largest city, and it straddles two kinds of ground: limestone on the west side and Blackland clay to the east. It also has some of the clearest published permit rules in the area, down to the fee for an uncovered deck. We build decks, covered patios, pergolas, gazebos and screened porches in Round Rock and handle the city permit and HOA approval.
Permits, HOAs, soil and local building tips for Round Rock
"Round Rock is easy to plan if you start with the city's rules. Five feet off the side and back property lines, nothing in an easement, and the review takes a while. So we lay the deck out against your survey on day one. Then we look at the dirt, because the west side and the east side are two different jobs."

Why Sunrooms & Screened Porches Matter Here
Central Texas has one of the longest mosquito seasons in the country - roughly February through November in a warm year. That means an open patio is a battle for most of the year, and an uncovered one is unusable all summer. A screened porch gives you the breeze without the bugs. A sunroom goes further: real windows, real comfort, and usable square footage in January and August alike. Either way, you're converting space you avoid into space you live in - and quality enclosed outdoor space is one of the features Austin-area buyers consistently pay attention to.
Bug-Free Outdoor Living
Mosquitoes are the number one reason Central Texas patios sit empty. A properly built screen room ends that problem completely - evenings on the porch from spring through fall without a citronella candle in sight. We build tight: screen panels tensioned correctly, doors that seal, and no gaps at the roofline where bugs sneak in.
Built as a Real Structure
We don't staple screen to an existing patio and call it a screen room. We frame screened porches and sunrooms as true structural additions - engineered posts and beams, proper roof tie-in, correct flashing where it meets your house. That's the difference between 5 years and 30 years.
Three Levels of Enclosure
Screened porch, three-season room, or four-season sunroom - we build all three and we'll tell you honestly which one fits your budget and how you'll actually use the space. Plenty of clients start with screens and upgrade to windows later; we can design for that from day one.
Convert What You Already Have
If you have a covered patio or a solid deck, you may be closer to a screened porch than you think. We assess the existing structure, tell you straight whether it can carry the new loads, and quote the conversion at a fraction of a ground-up build when the bones are good.
