Tomball's Unincorporated County Rules vs. City Permitting

How permitting differs for a pool just inside versus just outside Tomball city limits.

Two Different Permitting Paths

A pool inside Tomball city limits goes through the city's building department; a few hundred yards outside, on unincorporated Harris or Montgomery County land, it goes through the county instead, each with its own forms, fee schedule, and inspection process.

Confirming Jurisdiction First

Because the Tomball city line doesn't always match what residents assume, confirming jurisdiction (a quick county/city GIS lookup) is one of the first steps in design, before assuming either permitting path applies.
