Common questions from 4-Bed Barndominium shoppers.
The questions our team hears every week. Click any to expand the short answer.
How thick is the steel on a Steel and Stud 40×100 metal building?
Standard frame: 14-gauge (1.5 mm) galvanized tubing. Optional 12-gauge upgrade (2.5 mm) for high-wind/snow zones. Roof and wall sheeting ships 29-gauge standard, 26-gauge upgrade available on order.
Does Steel and Stud deliver and install in my state?
Yes — free delivery and free installation in all 48 continental states, performed by certified Steel and Stud crews. Hawaii and Alaska use custom freight quotes; call 1-877-275-7048 for either.
What's the typical lead time for a 40×100 building?
Standard: 3–5 weeks from order confirmation to install completion. Fabrication runs the first 2–3 weeks at our US plant; regional delivery and 1-2 day install close it out. Rush builds available for $345.
Can I finance a Steel and Stud building without a credit check?
Yes — Steel and Stud's rent-to-own partner does not pull credit. Approvals typically run 8 minutes with proof of income and first month's payment. 36–60 month terms, no early-payoff penalty.
What's covered under the 20-year warranty?
Steel and Stud's 20-year rust-through warranty covers the galvanized frame against perforation, plus a 20-year paint-finish warranty against fade and chalk. Workmanship on the install is warrantied for 1 year. Warranty transfers to the next owner on resale.

4-Bed Barndominium questions, answered.
What's actually included in the $77,450 shell?
Shell scope: structure + insulation pre-pack (R-19 walls / R-30 ceiling) + plumbing rough-in (kitchen + bath drain/supply) + 200A electrical entrance + HVAC mini-split rough-in + 4 egress windows per residential code. Finish-out trades (drywall, paint, flooring, cabinets, fixtures) are owner-supplied — plan $25,000 to $55,000 in trades depending on finishes.
Can this be permitted as a primary residence?
40×100 barndominium shell meets IRC framing/ceiling/egress requirements when finished to code. The structure ships with stamped engineered drawings for residential occupancy in your wind/snow zone. Permitting is handled by your local building department, file the drawings plus your finish plans for the C of O.
Property taxes after the barndominium?
Typically $25,000 to $80,000 assessed-value increase, $300 to $1,800/yr added property tax depending on county. Long-term rental income covers this 5 to 12× over.
What's the realistic total to move-in-ready?
Shell ($77,450) + slab/foundation ($8,000-$15,000) + finish trades ($25,000-$55,000) + appliances/fixtures ($6,000-$15,000) = roughly $107,450 to $162,450 total. Compare to ~$300-$450/sqft for new conventional construction.
How long to move-in-ready?
Shell goes up in 2 to 3 weeks. Finish trades 8 to 14 weeks depending on your contractor. Full move-in-ready in 3 to 5 months on average.
Financing options?
Construction loan for the shell + slab, then conventional mortgage on the finished build. Some lenders offer a single-close "barndo loan" that bundles everything; ask your local bank for "construction-to-permanent" products.
