Tomball, TX Swimming Pools & Spas: Above-Ground Pools (2026)

Tomball's building code applies the International Residential Code requirements to above-ground pools. Permanent above-ground pools with plumbing, electrical connections, or decks require a building permit from the Community Development Department. Above-ground pools with walls at least 48 inches above the adjacent grade may use the pool wall itself as the required barrier, provided the access ladder or steps are removable, lockable, or surrounded by a barrier with a self-closing, self-latching gate. If the pool wall is less than 48 inches above grade at any point (due to sloping ground, adjacent decks, or built-up landscaping), a separate barrier must be installed to achieve the 48-inch minimum. Electrical connections for pumps, filters, and other equipment must comply with the National Electrical Code including GFCI protection. Pools must be located outside of utility easements and comply with setback requirements from property lines. Temporary inflatable or soft-sided pools with a water depth of less than 24 inches are generally exempt from permit and barrier requirements but should still be supervised. Draining above-ground pools should be done in a manner that does not flood neighboring properties.
