Answers about the 18x40 Steel Carport, including pricing, layout, product options, free delivery and installation, and local project requirements.

This specific configuration lists a 6-foot leg height. Overall width and length do not establish adequate vehicle height clearance. Confirm the lowest usable clearance against your vehicle, including rooftop equipment, before ordering; taller vehicles may require a taller configuration.
Confirm permits, zoning, setbacks, foundation requirements, and required wind, snow, and seismic design criteria with your local building department before ordering. Requirements depend on your address and intended use. Ask ProBuilt which certification and engineering documents are available for your project; a listed wind rating alone does not guarantee local approval.
