The Communities We Build In

Where Summit Oak Builders Builds

We work out of an office on FM 3159 at Canyon Lake and build custom homes across the Texas Hill Country and along the I-35 corridor, from Fredericksburg to Kingsbury. We keep that range deliberate. We take on a limited number of homes at a time and keep the range close enough that we can actually stand on your site rather than manage it down a phone.

Below are the communities we build in, grouped by county — because the county is what determines who permits your build, who inspects it, and in a couple of cases whether anyone inspects it at all.

Where we build most often

Comal County

Canyon Lake — Our home ground, and where the office sits. Unincorporated county land: septic, wells, steep lakeview lots and architectural committees in most subdivisions.

New Braunfels — Where we built our reputation before the office moved. The Balcones Escarpment runs through town, so the ground under your slab changes depending which side of it you build on.

Spring Branch — Unincorporated, with bigger tracts than most. Out here the driveway, the power run and the water line are real budget lines before the house even starts.

Bulverde — An incorporated city whose mailing address reaches well beyond its limits. Which side of that line your lot sits on decides whether the City or the County permits your build.

Hays County

Wimberley — Steep valley ground where Cypress Creek meets the Blanco River. Wells are permitted through a groundwater district, and the town’s dark-sky expectations shape exterior lighting.

San Marcos — The most regulated ground we build on, and reasonably so. Impervious cover limits over the Edwards recharge zone effectively size the house before design begins.

Blanco County

Blanco — Ranch country out toward the western Hill Country. Outside the city there is generally no building permit and no framing inspection, which makes who you hire the only real safeguard.

Guadalupe County

Seguin — The one place we build that is not Hill Country. The limestone gives out and you are on expansive clay, which changes foundation engineering completely.

We also build in

Beyond the communities above, we build custom homes throughout the surrounding Hill Country and the I-35 corridor. The same approach applies: we walk the land first and tell you what it will take to build there.

West into the Hill Country

Boerne — Kendall County, northwest along I-10.

Comfort — Kendall County, on the Guadalupe River west of Boerne.

Fredericksburg — Gillespie County, in the heart of the Hill Country.

Johnson City — Blanco County, on the Pedernales River.

North along I-35

Dripping Springs — Hays County, on the western edge of the Austin area.

Kyle and Buda — Hays County, along I-35 between San Marcos and Austin.

East and south

Selma, Schertz and Cibolo — on the northeast side of San Antonio.

Kingsbury — Guadalupe County, east of Seguin.

Martindale — Caldwell County, on the San Marcos River east of San Marcos.

What changes when you cross a county line

People assume a Hill Country build is a Hill Country build. It is not. Permitting authority, water source, soil and inspection regimes all change at county lines, and sometimes at city limits inside them. This is the short version of what we carry between jobs.

Comal County: city and county mixed

Canyon Lake and Spring Branch are unincorporated — county permitting, septic and wells. New Braunfels and Bulverde are cities with their own departments and inspections. Much of the county sits over the Edwards Aquifer recharge zone.

Hays County: two different halves

Wimberley and San Marcos share a county and not much else. Wimberley is wells, steep ground and floodplain along the Blanco River; San Marcos is city code, cover limits and tree protection over the aquifer.

Blanco County: almost no oversight

Rural, and light on regulation. Outside the city there is generally no building permit or framing inspection at all — septic and floodplain only. The standard is whatever your builder holds himself to.

Guadalupe County: clay, not rock

East of the escarpment the rock gives out and you are on expansive clay that moves with moisture. Foundation design and drainage matter more here than slope ever will.

Common questions about where we build

How far will you travel to build?

We build across the Texas Hill Country and the I-35 corridor: Comal, Hays, Blanco, Guadalupe, Kendall and Gillespie counties, and into Bexar and Caldwell. We take a limited number of projects at a time precisely so distance never becomes an excuse for not being on site. If our schedule will not let us do your job properly, we will say so rather than take it.

Ask us. If it is close to where we already work, very likely. If it is far enough that we could not be on site when it matters, we will tell you that instead of stretching ourselves and doing you a disservice.

Yes — most of our homes are built on land the owner brings us. If you have not bought yet, talk to us first. We will review the tract for access, slope, soil, septic feasibility, water and floodplain before you are committed to it.

No, and that is the point of this page. A slab detailed for Canyon Lake limestone is wrong in Seguin. A permitting schedule that works in Blanco County is meaningless in San Marcos. The house you want stays the same; what sits under it and who approves it does not.

On FM 3159 at Canyon Lake, Texas. We moved there from New Braunfels, and we still build in both — along with everywhere else on this page. Call 830-625-1111 or use the form below.

Have a lot in mind?

Send us the address and we’ll walk it — access, slope, septic feasibility, water, and what it will genuinely cost to build on. Before you close, not after.
