Ready to make it real?
You've got your number. Here's how Denton County folks actually get it built.
Build your barndominium in Denton County, Texas with accurate cost estimates.
What's actually under a Denton County barndo
Drilled well — Trinity aquifer, 350–550 ft down · $8k–$35k
Aerobic septic — the clay won't perc, so it's required · $8k–$12k + $400 permit
Power from the road — $3k–$8k (much more on a long rural run)
Engineered slab — clay soil demands it, baked into the build
Not to scale — a 550-ft well is deeper than this whole page. That's the point: your number includes what's under the dirt, not just the building.
How we calculate this
You pick a build (by bedrooms or by size) and tell us about your land in plain English — where, how big, what finish.
We translate that into real Denton County costs: Trinity-aquifer well depth, the septic type the soil forces, permit rules, and how far power has to run.
Every line shows a low–median–high range, not a blind average, so outliers don't distort your number.
Know a real figure (a well quote, your land price)? Enter it and that line locks to your actual cost — the estimate converges on reality.

What this estimate does not include
Where these numbers come from
These costs are modeled from public Denton County records and real, published build-cost reports from owners and builders — shown as low–median–high ranges, never a blind average, and updated 2026-06. Sources: Denton County OSSF fee schedule; Trinity Aquifer well data; Active land listings. Note: Texas is a non-disclosure state, so true land sale prices aren't public — land figures are modeled from active listings by acreage band, which is exactly why entering your own parcel price gives the most accurate result.
