Homes and lots in Double Oak
A 1980s town
By the U.S. Census Bureau's 2020–2024 survey estimates, 464 of Double Oak's 1,107 housing units went up in the 1980s, or 41.9%, and 649, or 58.6%, before 1990. The median home was built in 1988, give or take two years, and only 27 units date from 2020 or later. The Handbook of Texas tracks the same boom in people: 836 residents in 1980, 1,664 in 1990 and 2,179 in 2000.
Single-family homes on an acre or more
Detached single-family houses make up 1,096 of the 1,107 units in that survey, and owners live in 97.6% of the occupied homes. The Town calls itself a general law city restricted to single-family homes on lots of at least one acre, with a commercial area in the northeast of its limits. Its zoning asks for homes of at least 1,600 square feet in the Single-Family district and 2,300 square feet in the Ranch Estate district, both on lots of an acre or more, and it lists a swimming pool cabana among the uses allowed for a major accessory building. The survey puts the median owner-occupied home at $736,600.

The 2018 edition on the Town's list
Double Oak's Development Services page lists the codes the Town follows as the 2018 editions of the International codes, the International Swimming and Spa Code among them, along with the 2017 National Electrical Code. The adopting section of its Code of Ordinances, § 3.201, takes up the 2018 International codes with the North Central Texas Council of Governments' regional amendments, yet its list names no pool code. Ask the Town's plan reviewer which pool code and edition it will check your plans against.
From a diving pool to a Type O pool
The figures on this page come from the 2021 International Swimming Pool and Spa Code. That edition sorts residential pools suited to diving equipment into Types I to V and calls a nondiving pool Type O, on which no board or other diving equipment may be installed. Even its smallest diving types call for water 7 feet 6 inches deep at Point B and 6 feet at Point A, so a deep end filled in below those depths leaves a Type O pool and the board comes off.
Depths and slopes after the fill
For the pool that remains, the same edition sets the shallow end between 33 inches and 4 feet deep, puts the first change of floor slope no less than 33 inches under the waterline and no closer than 6 feet to where the shallow end begins, and lets the deep floor slope no steeper than 1 in 3. If part of the pool is still deeper than 5 feet, the code wants a way in and out there as well, and a pool with a slope break gets a rope and float line 1 to 2 feet toward its shallow side.

(469) 526-3886Permits for pool work in Double Oak
The Town requires a building permit for all new construction, remodeling, and changes or additions to structures, and it names swimming pools in that rule. Its list of work needing a permit includes “Pools & Hot Tubs” and “Additions and Remodels”, and a project started before its permit is approved is subject to double permit fines. The Town's pages don't say whether a deep-end conversion goes under the pool line or the remodel line, so put that question to Development Services before the pool is drained.
Reviews, inspections and fees
A third-party contractor handles the Town's building inspections and permit reviews. Double Oak has no contractor registration, though a contractor must file the permit application or be listed on someone else's. The fee schedule shows no separate line for an in-ground pool; it lists an in-ground spa with its fence at $325, flatwork at $85, and additions or remodels under 1,200 square feet at all required permits, not to exceed $500. When a private pool or spa inspection needs a second reinspection, a $35 fee is paid first, under an ordinance adopted in 1987.
Fences and setbacks
The zoning ordinance calls for a fence at least 4 feet high around in-ground and above-ground pools, with no gap or opening wider than 4 inches and gates that close and latch by themselves. A pool must sit at least 4 feet from the property line or road easement, measured from the water's edge, and a fence permit issued with a pool permit is good for 60 days.
Flower Mound Pool Resurfacing will lay out the Town's permit steps before any work is scheduled.

(469) 526-3886Soil, water and the refill
Sandy loams with moderate clays
Inside Double Oak's Census boundary, the USDA soil survey maps Gasil fine sandy loam on about 30.8% of the land at 1 to 3 percent slopes and on another 9.2% at steeper slopes, with Birome fine sandy loam at 15.0% and Callisburg fine sandy loam at 10.2%. Gasil's linear extensibility, the survey's measure of how far a soil swells as it wets, is 1.8 percent, low on the 1980 county survey's scale; Birome and Callisburg reach 4.5 percent, which that survey counts as moderate. In its words, soils rated moderate or higher can damage structures as they shrink and swell, and special design is often needed.
Water from Cross Timbers
Cross Timbers Water Supply Corporation serves most of Double Oak, as it does most of Bartonville and Copper Canyon. Its 2025 water quality report names ground water from the Trinity Sands and Paluxy aquifers and surface water from the Upper Trinity Regional Water District, and it prints no hardness figure, so the fill water is worth testing before a new finish goes in.
Refilling under the drought plan
On October 4, 2026, the corporation's home page showed Stage 2 (Yellow) restrictions. Its Demand Management Plan, revised in August 2022, makes filling a new pool in Stage 2 a scheduled job, with three days' written notice to its office, which assigns a time. Stage 3 schedules the filling of any pool the same way and holds the Double Oak zone to Friday watering, and Stage 4 prohibits refilling drained pools, so check the stage before a converted pool is emptied.
History: a schoolhouse name and a volunteer town
The area had a school district as early as 1884, according to the Handbook of Texas, and the town is named after the old Double Oak School, which stood on McMakin Road. It grew out of James F. “Bill” Brittain's plan for a tax-free municipality in south central Denton County, became a town on May 25, 1974, with 243 residents, and elected J.R. Griswald its first mayor on June 29 that year. It covers roughly 2 1/2 square miles, and the Town still calls itself a volunteer town, where residents have fixed streets on “Pot Holes Days”, kept the town's gardens and staffed the Double Oak Volunteer Fire Department.
Children go to Lewisville ISD schools (Flower Mound Elementary, Clayton Downing Middle School and Marcus High School) or Denton ISD schools (Adkins Elementary, Tom Harpool Middle School and Guyer High School), depending on where they live. Bartonville's first incorporation, in 1960, took in Double Oak and Copper Canyon too, before its residents voted to dis-incorporate. Copper Canyon still shares a border with Double Oak; for its spa and barrier rules, see adding a spa to a pool in Copper Canyon.
Other pool work alongside a conversion
Since the pool is drained and resurfaced anyway, ask about anything else it needs while it is empty. Flower Mound Pool Resurfacing also handles pool replastering, pebble and quartz finishes, waterline tile and coping repair, and tanning ledge and pool step additions for homes in and around Double Oak. Lantana, to the north, has amenity pools of its own; HOA pool resurfacing in Lantana explains the state rules they fall under.
How a diving pool conversion runs
In the order the Town's rules and the work itself set:
Ask the Town first
Development Services says whether the job is a pool permit or a remodel, and its third-party reviewer checks the plans. Nothing starts before approval, since early work draws double permit fines.
Check the water stage
Cross Timbers’ stage on the day decides whether the refill needs three days’ written notice and an assigned time, or, in Stage 4, whether a drained pool may be refilled at all.
Drain and fill in the deep end
The pool is drained and part of the deep end is filled in, with the new slope change, floor slope and walls set to the code the Town applies. The board comes off, since a Type O pool takes no diving equipment.
Resurface
The whole pool gets a new finish, the last of the three steps in the deep-to-shallow figures, chosen like any resurfacing: plaster, quartz or pebble.
Inspection
The Town’s third-party inspector checks the work; if a second reinspection is needed after noted violations, its $35 fee is paid first.
Refill and start-up
The refill follows Cross Timbers’ schedule for the current stage, and the new finish then goes through its start-up.
