Barndominium & Metal Building Builder in Katy, TX
Katy is about a 34-mile drive south of our Magnolia office, typically by way of the Grand Parkway (SH 99). The city sits at the junction of Harris, Fort Bend, and Waller counties, along Interstate 10, US 90, and FM 1463. That incorporated city is only a small part of what people mean when they say they live in Katy. Around it are master-planned neighborhoods and, especially toward Brookshire, Fulshear, and the less developed county edges, remaining acreage that can still support a metal building, a barndominium shell, or a move-in-ready custom home.
Exteriors of Texas (EOT Builders) serves the Katy area from Magnolia. In the suburban core, deed restrictions and city zoning often do not allow a barn-style house or a large metal shop. The work we take on is usually on less restricted tracts — rural and semi-rural acreage on the northwest, west, and southwest sides of the area, including land toward Waller County, Brookshire, and Fulshear.
What we build in the Katy area
- Metal buildings for workshops, storage, and agricultural use on lots that allow them, with openings and clear height planned around your equipment.
- Barndominium shell packages if you want the structure closed in first and prefer to finish the living space on your own timeline.
- Turnkey barndominiums and custom homes when you want a finished, move-in-ready house and the property’s rules support that design.
A Katy mailing address does not tell us whether a shop and a house can share the same tract. We start with the deed restrictions, the survey, and the correct permit office, then plan the driveway, drainage, and building placement together.
Typical pricing
These figures are typical ranges. Design, site conditions, and finishes determine where a specific project lands.
- 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.
Acreage west and northwest of Katy often needs more work outside the building than a neighborhood lot — land clearing, a longer driveway, 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 around Katy: local considerations
The first question is which office governs the tract. The City of Katy spans Harris, Fort Bend, and Waller counties, and a “Katy, TX” address may sit inside the city, in unincorporated land in any of those counties, in a nearby city such as Fulshear or Brookshire, or in a city’s extra-territorial jurisdiction. We confirm that on the appraisal-district record and official maps, not from the postal city.
Inside Katy city limits, the City issues building permits for new homes, additions, and many accessory buildings — including garages, shops, and storage buildings — through its Civic Access portal. It has adopted the 2021 International Residential Code and related International codes, and it also administers zoning. A metal building or barn-style house may need planning review as well as a building permit. The City’s residential survey rules set a minimum finished-floor height: 12 inches above the centerline of the front street, 18 inches above the top of the curb, or 12 inches above base flood elevation, whichever is higher.
On unincorporated land, the county changes the paperwork. Harris County tracts go through the Office of the County Engineer for a residential development permit, floodplain review, and driveway or culvert access. Drainage deserves an early look in this part of the county, including areas in the Barker Reservoir watershed; floodplain permits still come from the county or city, not from the Harris County Flood Control District. Fort Bend County requires a Development Permit for new residential structures of 400 square feet or more, and for work in the 100-year floodplain, filed online, usually with CenterPoint address verification, a site plan, and a grading plan. Septic design goes through the Fort Bend County Health Department when the tract is not on public sewer, and a new driveway or culvert may be a separate permit. Waller County requires a 9-1-1 address before other permits, then a residential building permit and, for most new county-road driveways, a culvert permit, plus septic and floodplain filings when they apply.
If the tract is inside Fulshear or its ETJ, or inside Brookshire, that city — not the county — issues the building permit. Fulshear requires a city permit in both the city limits and the ETJ. Brookshire has its own office for new residential construction, driveways, and floodplain work.
Deed restrictions and HOA covenants can decide the project even when the city or county would otherwise allow the building. We ask to read those documents before drawing a plan the association will not approve.
How a Katy-area project typically proceeds
- Request a quote at our contact page with ZIP, project type, size, land status, and timeline.
- Confirm the jurisdiction — City of Katy, another city, a city ETJ, or unincorporated Harris, Fort Bend, or Waller County — and review deed restrictions, then walk the site for drainage and access.
- Prepare plans and file the correct permits, including floodplain, driveway or culvert, and septic filings when they apply.
- Build the metal building, shell, or finished home.
- Walk the project with you and complete city or county close-out, including elevation documentation on floodplain lots.
FAQ
I have a Katy address. Who issues my permit?
It depends on the lot, not the mailing address. The City of Katy, the Cities of Fulshear or Brookshire, or the Harris, Fort Bend, or Waller County permit office may be in charge. We confirm this on the tax record and official maps before we file anything.
Will my HOA or the City allow a barndominium or metal building?
Many Katy-area associations will not, or they will limit exterior materials and use. Inside the city, zoning can add another review. Read the deed restrictions first. If they prohibit the building you want, we can talk about less restricted acreage toward Brookshire, Fulshear, or the Waller County edge of the area.
How far is your office from Katy?
It is about a 34-mile trip from our Magnolia office, typically by way of the Grand Parkway. That is a longer run than Tomball or Waller, but it is a corridor we already serve, and we plan site visits around it.
