Tomball sits about 11 miles southeast of our Magnolia office, along SH 249 and FM 2920, at the northern edge of Harris County. The incorporated city has a clear downtown and neighborhoods, but many people who use a Tomball address actually live on acreage just outside the city, in Harris County or across the line in Montgomery County. That is usually where a metal building or barndominium is the most practical fit.

Exteriors of Texas (EOT Builders) works with Tomball-area landowners who want a shop, a barndominium shell, or a move-in-ready custom home on land that can support it. Tomball is a short trip from Magnolia on SH 249, and we treat this corridor as part of our regular service area.

What we build in Tomball

  • Metal buildings for personal shops, storage, and small business use, laid out for your vehicles, equipment, and workshop flow.
  • Barndominium shell packages that close in the structure so you can finish the interior in a later phase.
  • Turnkey barndominiums and custom homes built to a move-in-ready standard, including interior finishes.

Inside many Tomball subdivisions, deed restrictions or HOA rules may limit metal exteriors or non-traditional house styles. On unrestricted or lightly restricted acreage west and north of town, toward Hockley, Magnolia, and Decker Prairie, those buildings are a more natural match.

Typical pricing

Pricing is a typical range and depends on design, the site, and finishes.

  • Shell-only packages typically start around $50–$80 per square foot.
  • Move-in-ready custom builds typically run $130–$200 per square foot under roof.

A city lot with existing utilities prices differently than a raw Harris or Montgomery County tract that needs land clearing, a driveway culvert, a septic system, a water well, or an electrical tie-in. Those items are not included in the per-square-foot price and are quoted separately.

Building in Tomball: local considerations

Jurisdiction is the first question. Inside Tomball city limits, the City’s Building Office reviews plans and issues building permits under the city’s adopted codes (including the International Residential Code) through its SmartGov portal, and the city inspects the work.

Outside the city, the rules change by county. Unincorporated Harris County projects go through the Harris County Office of the County Engineer, which issues a residential development permit and reviews floodplain, platting, and driveway or culvert access. Unincorporated Montgomery County land requires a county Development Permit, a septic permit when you are not on public sewer, and floodplain elevation compliance if you are in or within 100 feet of a special flood hazard area.

A Tomball ZIP code or mailing address does not tell you which office is in charge. We check city limits and the appraisal-district record before design is finalized.

How a Tomball project typically proceeds

  1. Send a quote request at our contact page with ZIP, project type, size, land status, and timeline.
  2. Confirm jurisdiction and walk the site, including SH 249 or FM 2920 access, drainage, and any deed restrictions.
  3. Complete design and permits with the City of Tomball, Harris County, or Montgomery County, whichever applies, plus septic when needed.
  4. Build the metal building, shell, or finished home.
  5. Walk the project with you and close out inspections or county documentation.

FAQ

My property says Tomball, but I am not sure I am in the city. Who issues the permit?
The City of Tomball only permits lots inside its limits. Many Tomball addresses are in unincorporated Harris County or in Montgomery County. We verify that on the official maps and tax record so the application goes to the right office.

Can I build a barndominium in a Tomball neighborhood?
Only if the zoning, plat, and any deed restrictions allow that use and appearance. Some neighborhoods will not. If the restrictions are a problem, we can talk with you about acreage options in the surrounding area.

Do you work on both sides of the county line?
Yes. Tomball sits in Harris County, and a short drive north or west puts you in Montgomery County. We build in both counties around Tomball.
