Metal Building Prices in California
Small starter carports in California typically cost around $4,000 to $5,000. Bigger garages, barns, and light commercial shells often run $30,000 and up. Your number depends on size, engineering, site work, and the options you pick.
Here is what usually moves the price
- Size and span: Once you reach 30 feet in width, you require heavier steel and stronger anchors to withstand seismic loads. That pushes cost per foot up.
- Steel and finish: Upgrading to 26-gauge panels adds life and dent resistance. Near the coast, galvalume or premium coatings help with salt air.
- Energy and insulation: Basic fiberglass often starts around $1 to $2 per square foot. Radiant barriers or spray foam cost more, but they effectively control heat and condensation.
- Doors and windows: Plan about $500 to $2,000 for a roll-up door and $100 to $300 for a standard window. Lean-tos, gutters, skylights, and interior framing are also factored into the total.
- Site and slab: A level pad and good truck access keep labor tight. Hillside work, long driveways, or tricky soils raise the bid.
- Wildfire and WUI: In designated areas, ember-resistant vents, Class A roof assemblies, and noncombustible trims may be required.
Certified engineering and proper anchoring save headaches at plan check and protect your budget over time.
