Before you build in Sunnyvale

Dallas County · Blackland Prairie soil

Sunnyvale has long enforced unusually large minimum residential lot sizes, so backyards there are substantially deeper than in neighboring Mesquite or Garland and many homes sit on roughly an acre. The town’s northern boundary runs along Lake Ray Hubbard.

That ground decides how a slab, a pool shell or a footing has to be built here. Here is what it does to a patio.

We file the permit with the City of Sunnyvale and follow it through review, so the schedule doesn’t stall on paperwork.

Longhorn has built across Dallas County and the wider Metroplex since 1984, and every project starts with a free design visit and a firm price.

Homes and Yards in Sunnyvale

Sunnyvale was incorporated in 1953 with zoning that allowed only single-family houses on 1-acre lots.

Bigger lots give a backyard room to breathe. The planning shifts to utility runs, drainage across open ground and, where there is one, keeping well clear of the septic field.

Sunnyvale lies along Lake Ray Hubbard. Open ground near the water tends to catch more wind, so shade structures are anchored and placed with the breeze in mind.

North Texas Municipal Water District (Sunnyvale is a customer of NTMWD’s regional water system).

Sunnyvale was incorporated on February 26, 1953, taking in the communities of New Hope, Tripp, Hattersville and Long Creek, and the name was chosen by students of the Tripp-Long Creek school. The town had 1,000 residents in 1958, 2,228 in 1990, 2,693 in 2000, 5,130 in 2010 and 8,062 in 2021. The old New Hope school served as town hall in 1965, and the old New Hope area along Beltline Road became Main Street. Sunnyvale is on U.S. Highway 80 between Mesquite and Garland, about twelve miles east of Dallas.

The town’s 2024 Water Conservation and Water Resource and Emergency Management Plan was approved by the Town Council on April 22, 2024. No watering is allowed between 10 a.m. and 6 p.m., and watering days are assigned by a water zone map.

Pool and spa permits follow the 2021 International Swimming Pool and Spa Code. A pool or spa must sit at least 3 feet from the rear and side property lines, at least 5 feet from all other structures, outside any easement, and clear of a 1:1 ratio from the building foundation; it must also be at least 25 feet from the spray area of an aerobic septic system. Equipment may not be in the front yard. The submittal includes a pool plan stamped by the electrical service provider, a notarized Pool Construction affidavit covering dirt removal and disposal, and a Pool Protection Device affidavit confirming the pool alarm; the final inspection checks the barrier and door and window alarms. Town Hall is at 127 N. Collins Road, 972-226-7177.

What each outdoor project needs in Sunnyvale, TX

How is a pool built in Sunnyvale?

Blackland Prairie clay swells through a wet spring and shrinks hard by August, and a pool shell is a rigid object sitting in ground that moves around it. Here that means the shell, the beam and the deck are engineered for that movement from the drawing stage, and the flatwork gets its control joints placed on purpose rather than wherever the pour ends. In Sunnyvale the permit goes through the City of Sunnyvale, and Longhorn files it and follows it through inspection. More on pools.

What does a patio cover need in Sunnyvale?

Blackland Prairie clay lifts and drops with the season, so a patio cover’s footings are the whole job. Posts set in shallow pads move with the top of the soil and take the roofline with them; footings taken below the active zone, tied to a slab that drains away from the house, do not. In Sunnyvale the permit goes through the City of Sunnyvale, and Longhorn files it and follows it through inspection. More on patio covers.

How is a pergola built to last in Sunnyvale?

On Blackland Prairie clay a pergola’s posts are what decide whether it still stands square in five years. The clay moves most in the top few feet, so footings go deeper than the movement rather than resting in it, and the slab underneath gets its own drainage plan. More on pergolas.

How a Backyard Project Runs in Sunnyvale

  1. 1

    A free design visit in Sunnyvale

    A designer comes out to the house, measures the space a backyard project has to fit, walks the access a crew would need, and talks through what you want it to do. You leave with a firm price. On Blackland Prairie ground, that is also when the grading, drainage and movement details get decided rather than improvised on site.

  2. 2

    Drawings, permit and HOA

    We file the permit with the City of Sunnyvale and follow it through review, so the schedule does not stall on paperwork. Where an HOA wants a submittal, we prepare the drawings it asks for.

  3. 3

    One crew, one schedule

    The same team builds the whole backyard project in order, so the slab, the structure, the electrical and the finish work are not three different companies working around each other.

  4. 4

    Walkthrough and warranty

    We walk the finished backyard project with you, settle the punch list and leave one warranty on the work, and we are still Dallas County-local if you need us later.

Sunnyvale outdoor living questions

Almost always, for pools and for anything attached to the house, including patio covers, sunrooms and enclosures. Longhorn files the permit with the City of Sunnyvale and handles the inspections, so the schedule does not stall on paperwork.

Sunnyvale sits on Blackland Prairie ground in Dallas County. The ground decides how a slab, a pool shell or a footing has to be built, so we plan the drainage and the footings for it at the first visit rather than after something moves.

Where an HOA in Sunnyvale asks for a submittal, we prepare the drawings and details it wants, alongside the city permit, so the approval runs in parallel with the design rather than after it.

Yes. Many homeowners start with one piece, such as a pool or a patio cover, and add the rest later. We plan the whole space up front so the gas, power, water and drainage for later phases are in place from the start.
