Swimming Pool permit in Lewisville, TX
Yes — you need a permit for swimming pool work in Lewisville.
Installing an in-ground or above-ground pool or spa needs a permit. The city adopted the 2021 International Swimming Pool and Spa Code (Sec. 4-483) with amendments, and its permit and inspection rules apply to pools serving one- and two-family homes.

Most building codes exempt a prefab pool under 24 inches deep. Lewisville is stricter — a permit applies at any depth.
How to pull the permit
- Put together a site plan showing where the work goes, with dimensions.
- Apply through the Lewisville building department.
- Pay the permit fee when the permit is issued. Work done before that isn't covered.
- Book each inspection listed on the permit as the job reaches that stage.
Either of you can pull it. When a contractor does the work, it is normally their job.
If you skip it
If you start pool work before getting the permit, the city adds an investigation fee equal to the permit fee, on top of the permit fee (ISPSC 108.4).

Questions people ask
How much does a swimming pool permit cost in Lewisville?
Pool permit fees are set by the city fee schedule (Sec. 2-201 / ISPSC 108.2).. Valuation-based fees mean the number depends on what the job is worth, so the department quotes it when you apply.
I already built it without a permit. What now?
Lewisville can issue a stop-work order and require you to apply after the fact, sometimes with an extra fee. Work that was covered up may have to be opened for inspection. Full walkthrough here.
Does unpermitted work cause problems when selling the house?
Often, yes. A buyer's inspector or the title company may flag it, and lenders can balk at financing a home with open or missing permits. What to do about it.
