Barndominium and barn builders in Boerne, Texas
Boerne is the fast-growing front door of the Hill Country, where San Antonio gives way to ranch land along I-10. Buyers here want barndominiums, shops, and family compounds on small to mid-size acreage, and the market is active. The one Edwards Aquifer wrinkle in Kendall County sits right here.

Building around Boerne
Boerne is the seat of Kendall County, set along Cibolo Creek with its well-known Hill Country Mile downtown and the Cibolo Center for Conservation nearby. Growth pushes north and west off I-10 into ranchettes and acreage subdivisions. Buyers are often families and professionals leaving San Antonio for a few acres, plus established ranch owners. Projects skew to barndominium homes, big shops, and combined home-and-shop builds.
Barndominium builders in Boerne, TX
Barndominiums and metal building homes lead, with workshops and garages close behind because so many buyers want shop space for vehicles, an RV, or a home business. Horse barns appear on the larger western tracts.
Barndominium contractors around Boerne stay busy because the Kendall County acreage north and west of I-10 is where San Antonio families go to build a custom home with a shop attached. Most projects here are turnkey: a general contractor runs the post-frame or steel construction, the slab, the interior finish and the septic together and hands over a finished metal home. Ask a Boerne barndominium builder two things before you sign: whether they have taken a job through the Kendall County development-permit process, and whether they have checked the Edwards Aquifer recharge map for the southeast corner of the county, where a parcel can trigger a TCEQ review that changes the construction schedule.
Texas licenses no home builders or general contractors, so the checks that protect you are the ones you make yourself. How to choose a barndominium builder in the Hill Country walks through them: the trade licenses that do exist, the insurance certificate, the homestead contract rule and the shape a quote should take.
Permitting in and around Boerne
Inside the Boerne city limits, city building permits apply. In the city's one-mile extraterritorial jurisdiction they do not: the city's own development code FAQ lists subdivisions, platting, stormwater, infrastructure and signage as what reaches the ETJ, and building permits are not on that list. Out in unincorporated Kendall County, the county runs a development-permit process rather than a building code, covering septic, addressing and access, though a commercial building there does go through the county Fire Marshal. The Edwards Aquifer rule is one thing you can set aside here: 30 TAC Chapter 213 names eight counties and Kendall is not among them. The Kendall County permitting page explains it.

Site notes for Boerne land
Boerne-area land is classic Hill Country limestone, so wells can be deep and septic is usually an aerobic unit. Engineer for roughly 105 to 115 mph design wind, more on the exposed ridges north of town, and budget for rock in the pad and post holes.
What it costs, and what happens after you send it
- How much does a barndominium cost?
- A finished barndominium around Boerne runs $150 to $350 per finished square foot in published planning ranges, plus roughly $43,000 to $156,000 of Hill Country site work that most calculators leave out: aerobic septic, a well, limestone work, engineered plans and published electric fees. Those are third-party figures verified as of July 27, 2026, not our prices and not a quote. The cost calculator shows the publisher and date behind every band and lets you run your own square footage.
- How fast will someone get back to me?
- Your request goes to one independent builder, usually within about an hour during the day. The builder then contacts you to arrange a site visit and price the work on their own schedule.
- What building types are covered?
- Barndominiums, horse barns, workshops, equipment and hay barns, garages, covered arenas, commercial metal buildings and the concrete slabs under them. See every building type.
Only the builder who walks your site can price your actual project.

Boerne building questions
Is my Boerne-area land in the Edwards Aquifer recharge zone?
Not under the TCEQ rule. Chapter 213 names eight counties and Kendall is not among them, so a Boerne-area build files no Water Pollution Abatement Plan and no Contributing Zone Plan, and skips the TCEQ review those add across the line in Comal County. The regulated zones are whatever TCEQ's maps show, so if your tract sits toward the Comal County line, check the TCEQ Edwards map viewer for your parcel. See the [Kendall County permitting page](/counties/kendall/) for the full reading.
Do I need a building permit to build a barndominium near Boerne?
Inside the City of Boerne or its ETJ, yes, through the city. In the unincorporated county, there is no general building code, but you go through the Kendall County development-permit process, which includes the septic permit. Check the Kendall County permitting page for specifics.
