Frequently Asked Questions
How much does a pole barn cost per square foot?
A basic pole barn (open sides, metal roof/siding) costs $8-12 per square foot for materials. A fully enclosed standard barn is $15-25/sqft. With insulation, concrete floor, and finishing, expect $25-45/sqft. Labor adds 40-60% to material costs.
How deep should pole barn posts be?
Pole barn posts should be buried at least 4 feet deep, or below the frost line plus 6 inches, whichever is deeper. Posts are typically set in concrete collars. For a 12ft sidewall, use 16ft posts (12ft above grade + 4ft buried).
