Barndominium or Custom Home: What Really Differs?
Barndominiums and traditional custom homes can both make great Texas homes, but they are framed, engineered and permitted differently.
Price per square foot varies widely by site, finishes and builder, so compare real bids for your land rather than published averages.
JRH Engineering is a Structural Engineer, Civil Engineer and Land Development firm serving Texas, North Carolina and Florida.
JRH guiding principles are: Engineering Excellence. Delivered on Time. Built on Value.
Key Differences
Framing: barndominiums often use steel or pre-engineered metal building (PEMB) frames; custom homes usually use wood framing
Interior space: steel frames allow tall ceilings and wide clear spans with fewer interior bearing walls
Foundations: both need a foundation matched to the soil, such as a post-tension slab, pier-and-beam or deep foundation
Supplier coordination: PEMB column reactions and anchor bolt layouts must be coordinated with the foundation design
Engineering Both Home Types Need
A geotechnical report on the soil (by others)
PE-sealed foundation plans
Site grading and drainage so water moves away from the home
Code review by the local building official, where one has jurisdiction
Project: Helical Pile Foundation, Custom Home, Mt. Enterprise, TX
Single-family custom home in Mt. Enterprise, Rusk County
Permitting through the City of Mt. Enterprise

Challenges
Site soils were unsuitable for conventional spread footings or a slab foundation
Several consultants had separate scopes, including a separate waterproofing designer
Objectives
Design a deep foundation to support the full home load.
Keep clear scope boundaries across the design team.

Barndominiums and Custom Homes in Texas, North Carolina and Florida
Texas
Texas cities follow minimum IRC requirements set by state law (Texas State Law Library); requirements in unincorporated areas depend on the county.
On expansive clay, post-tension slabs are common; see our Aledo post-tension case study and Post-Tensioning Institute resources.
For budgeting, see 2025 Guide: Breaking Down Barndominium Costs in Texas.
North Carolina
The NC Office of State Fire Marshal lists the 2018 NC codes as current, with 2024 pending; mountain and sloped lots often need engineered foundations.
Florida
Wind and flood zones shape both home types; see our Florida Building Code 9th Edition guide.
