Barndominium & Metal Building Builder in Willis, TX
Willis sits about 22 miles northeast of our Magnolia office, north of Conroe on the I-45 and SH 75 corridor, with FM 1097 running west toward Lake Conroe. The city itself is modest. Around it, especially west of the interstate and out toward the lake, there is still room for acreage, shops, and barndominiums. That mix — a small town with rural land close by — is what we build for.
Exteriors of Texas (EOT Builders) serves Willis from Magnolia. The drive is straightforward up I-45, and Willis is already on our published service-area list. If you have a tract here and want a metal building, a shell, or a move-in-ready custom home, we start by figuring out whether the City of Willis or unincorporated Montgomery County will permit the job.
What we build in Willis
- Metal buildings for workshops, boat and trailer storage, and equipment, with door heights planned for what you actually park inside.
- Barndominium shell packages if you want the structure weathertight first and the interior finished later.
- Turnkey barndominiums and custom homes for a finished, move-in-ready house.
West of I-45, toward FM 1097 and the lake, lots are often larger and less restricted than in-town parcels. In-town lots still work when the city’s codes and any plat rules allow the building type you want. We will look at both the land and the paperwork before recommending a plan.
Typical pricing
These are typical ranges, not a bid. Design, site conditions, and finishes set the price.
- 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 lake-area tract may need more elevation or drainage work than a high lot east of SH 75. Land clearing, a long driveway, a septic system, a water well, and electrical tie-in are not included in the per-square-foot price and are quoted separately.
Building in Willis: local considerations
Inside the city limits, the City of Willis Building Permits & Inspections office issues permits and inspects construction. If the lot is in the city, that is the office we use.
A Willis mailing address, though, often belongs to unincorporated Montgomery County. On that land, the county requires a Development Permit for new buildings and for grading, clearing, or fill. The county does not perform a final residential building inspection on homes outside the floodplain. You will typically need a county septic permit if you are not on public sewer, and each livable structure must have its own 9-1-1 address. Buildings in or within 100 feet of a special flood hazard area must be elevated at least two feet above base flood elevation, with elevation certificates.
For properties toward Lake Conroe, flood-map review is part of the first site look, not a late surprise.
How a Willis project typically proceeds
- Submit a quote request at our contact page with ZIP, project type, size, land status, and timeline.
- Confirm city or county jurisdiction and walk the site, including access from I-45, SH 75, or FM 1097 and any drainage or floodplain issues.
- Prepare plans and file permits with the City of Willis or Montgomery County, plus septic when needed.
- Build the metal building, shell, or finished home.
- Walk the project with you and close out inspections or county documentation.
FAQ
Is a Willis address always inside the city?
No. Many properties that use a Willis address are in unincorporated Montgomery County. The city only permits lots inside its limits. We check the appraisal-district record and city maps first.
Can I build west of I-45 toward the lake?
Yes, on tracts where floodplain and site conditions allow a compliant building. Those lots often have more room for a home and a shop, but they also need a careful drainage and elevation review.
Do you already serve Willis?
Yes. Willis is listed on our Service Areas page and in the site footer, and it is about 22 miles from the Magnolia office.
