11 Things to Check Before Buying Texas Land for a Barndominium

This is one of Texas's greatest barndominium advantages: in unincorporated areas, there are typically no restrictions on building a metal building as your primary residence.

Even in unzoned counties, agricultural land that carries a specific agricultural designation may have restrictions on permanent residential structures, or may require a minimum acreage before a residential building permit can be issued.

Always ask the county planning or appraisal district office directly: "Can I build a permanent residential barndominium on this parcel?"

Order a title search and specifically ask the title company to pull all deed restrictions, covenants, and conditions of record for the property. This typically costs $200–$500 and is worth every dollar.

Don't rely on the seller's disclosure — sellers don't always know their own deed restrictions.

Properties in VE zones, rare in most Texas inland markets, require pile foundations and significant additional costs.

This matters throughout Texas, not just near the coast. The Hill Country has flash flood zones along drainages that FEMA maps in detail. East Texas river bottoms have significant AE zone coverage. Even Central Texas parcels that appear to be on high ground can have portions in flood zones near seasonal creeks.

If any portion of the parcel is in an AE zone, get a preliminary Elevation Certificate, $500–$800, before purchasing to understand what your foundation elevation requirement and flood insurance premium will actually be.

A soil report from a licensed geotechnical engineer, $400–$700, before finalizing your land purchase is one of the highest-ROI due diligence expenses available.

It tells you exactly what foundation approach your specific parcel requires. Without it, you're guessing on what could be a $20,000 variable.

If the nearest power line is more than a quarter mile from your building site, budget $37–$50 per linear foot for line extension. A property one mile from the nearest line: $194,000–$264,000 in infrastructure costs before you pour a single yard of concrete. Ask your cooperative or POCO, Power Company, for an extension estimate before purchasing remote land.

Plan for $8,000–$25,000+ depending on depth. Hill Country wells can run 400–600 feet deep at $18–$25/foot. East Texas wells are often shallower, $8,000–$14,000 range. Get a well driller's estimate on the specific parcel.

Budget $6,000–$18,000 for a conventional septic system. If soil percolation tests, perc tests, fail — common on clay-heavy Central Texas parcels — you'll need an aerobic system, which costs $12,000–$25,000 and has ongoing monthly maintenance fees. Run a perc test before purchasing land with poor drainage characteristics.

Most rural Texas parcels have no natural gas service. Plan for propane, a 500-gallon tank installation runs $800–$1,200, or design an all-electric barndominium with heat pump HVAC and electric water heating.

Lenders require that financed properties have all-weather road access. A dirt path that becomes impassable in rain does not qualify. If you're creating a new driveway from a county road, budget $3,000–$15,000 for gravel or caliche base.

If creating access from a state highway, you need a TxDOT driveway permit — the fee is modest, $150–$300, but the approval timeline can run 60–90 days.

Confirm that the road access to your parcel is either owned by you or protected by a formal access easement recorded in the deed records. "I've always just driven through that neighbor's property" is not an easement and can be revoked.

Site work grading costs on a flat East Texas parcel: $3,000–$8,000.

Site work on a sloped Hill Country parcel requiring cut-and-fill, retaining structures, or rock removal: $15,000–$50,000+.

Get a topographic survey, $800–$1,500, on any parcel with visible slope before purchasing. The survey tells you your actual grade changes across the building site, which directly determines site preparation cost.

East Texas cedar, hardwood, and pine clearing costs: $1,500–$5,000 per acre depending on density.

Hill Country live oak clearing: $3,000–$8,000 per acre.

Some Texas counties have tree preservation ordinances that restrict removal of certain heritage trees, live oaks above a specific trunk diameter are protected in several Hill Country jurisdictions. Check with the county environmental health office before assuming you can clear freely.

Also check for any TCEQ, Texas Commission on Environmental Quality, regulated features: intermittent streams, wetland delineations, and floodplain buffers that may restrict where you can build even outside formal FEMA flood zones.

A 10-acre Hill Country parcel worth $800,000 might pay taxes based on agricultural productivity value — potentially reducing the annual tax bill from $12,000+ to $1,500–$3,000.

However: when you build a residential barndominium, the residential portion typically loses the ag exemption, reverting to market-rate taxation.

Plan for a blended property tax rate on your finished project: the portion of the parcel actively used for agriculture at agricultural rates; the footprint of the house and surrounding yard at market-rate residential rates.

If you want to maintain an ag exemption on the remainder of your acreage, plan your agricultural activity before you build: cattle grazing, hay production, beekeeping, or wildlife management are common Texas approaches.

Each requires documentation and active ongoing management.

These HOAs can and do prohibit metal building exteriors, mandate specific minimum home sizes, and ban shop buildings visible from the road.

Check the property listing's disclosure and the title documents for any HOA covenants.

This is standard in many Texas oil-producing counties and is not necessarily a dealbreaker — but you should know what you're getting.

Ask the title company to identify whether mineral rights are included in the sale or severed.
