How it works
Carports run $4,000–20,000 installed: a metal 2-car kit on gravel at the low end, a custom wood structure on concrete matching your house at the top. Per square foot, expect $15–25 for metal, $25–35 for wood, $40–55 for custom.
Metal kits win on price and speed (often installed in a day), but check the snow and wind ratings — the cheapest kits are rated for places without weather. In snow country, engineered trusses and proper footings are non-negotiable.
Attached carports cost ~10% less (the house carries one side) and feel like part of the home — but the ledger connection must be flashed and lagged to structure, not siding. Freestanding can go anywhere the setbacks allow.
Frequently asked questions
How much does a 2-car carport cost?
$5,000–9,000 for a metal kit installed on gravel/pavers; $10,000–18,000 for wood; $18,000–30,000+ custom-built to match the house.
Metal vs wood carport?
Metal: cheaper, faster, zero maintenance, utilitarian looks. Wood: 2x the price, beautiful, needs staining. Custom: matches the house, priced like a small addition.
Do I need a permit?
Usually yes — most jurisdictions treat carports as structures requiring permits, footings and setback compliance. Kit sellers who say "no permit needed" are selling, not advising.
What size for 2 cars?
20×20 ft minimum; 22×24 ft is comfortable (room to open doors). For trucks/SUVs, add 2 ft of width. Height: 8–9 ft clearance minimum.
Gravel, pavers or concrete base?
Gravel ($2/sq ft): cheapest, drains well, dusty. Concrete ($9/sq ft): clean, permanent, best for daily use. Pavers ($12/sq ft): pretty, pricier. Match the base to how you will use it.
Will it survive snow?
Only if rated for it — check the snow-load rating (psf) against your local code. Cheap kits rated 20 psf fail where 40+ is required. This is the #1 carport failure mode.
Attached or freestanding?
Attached: cheaper, convenient in rain, needs proper ledger flashing. Freestanding: flexible placement, full footings, ~10% more. Both need permits.
Can I enclose it later?
Plan for it now: size footings and posts for future walls, run electrical during construction. Converting a cheap kit later usually means rebuilding.
Does a carport add home value?
Modestly — appraisers credit covered parking below garage value. A handsome custom carport adds curb appeal; a rusting kit subtracts.
How long does installation take?
Metal kit: 1–2 days pro. Wood: 1–2 weeks. Custom: 3–6 weeks with permits. Concrete curing adds a week before posts go up.
