Every county in America gets a score from 0 to 100 based on how easy — or hard — it is to build a barndominium there. We pull data from federal, state, and county sources, weight the factors that actually matter to builders, and publish the results for free.
If you've ever tried to figure out whether you can build a barndominium in a specific county, you know the pain: conflicting blog posts, outdated forum threads, and county websites that haven't been updated since 2014.
AcreScore replaces guesswork with data. We score every county on the same criteria so you can compare apples to apples — whether you're looking at Blount County, Tennessee or Williamson County, Texas.
We're honest about limitations. Some counties have better data than others. Where we're uncertain, we say so. Where barndominiums genuinely aren't a good fit (dense urban counties, extreme flood zones), we'll tell you that too.
Each county is evaluated on 8 factors. The weights reflect what actually matters when you're trying to build — zoning is the #1 blocker, so it gets the most weight.
Can you legally build a metal-frame residential structure? Are barndominiums explicitly allowed, conditionally permitted, or effectively banned? Does the county even have zoning? Counties with no zoning or explicit barndo allowances score highest.
What percentage of the county is in a FEMA-designated flood zone? High flood coverage means expensive insurance, slab complications, and potential build restrictions. We use the National Flood Hazard Layer (NFHL) dataset.
Median price per acre for vacant/agricultural land. Barndominium builders need acreage — typically 3-15 acres. We compare against state and national medians to normalize across markets.
IECC climate zone, freeze/thaw cycles, and annual build-viable days. Metal buildings perform differently in Zone 2 (Houston) vs Zone 6 (Minnesota). Longer build seasons = lower construction costs.
Distance to nearest city (50K+ population) and nearest commercial airport. Most barndo builders want rural land with metro access — the sweet spot is 30-60 minutes from a city.
Median home value and 10-year population growth rate. Growing counties signal appreciation potential. We use Census ACS data — not Zillow estimates.
Availability of rural water, electrical co-ops, broadband coverage, and septic viability (soil class). Counties where you can realistically go off-grid or connect affordably score higher.
USDA Rural Development eligibility, property tax rate, and state-level barndominium financing friendliness. USDA eligibility alone can save builders 20%+ on financing costs through zero-down loans.
Barndo-friendly zoning, affordable land, low flood risk, good infrastructure. These counties actively welcome rural residential construction.
Buildable with conditions. You may need a variance, face higher land costs, or navigate stricter permit requirements. Do your homework on the specific parcel.
Significant barriers — restrictive zoning, high flood risk, expensive land, or urban density that makes barndominium construction impractical. Consider nearby counties instead.
