A permit checklist for backyard structures
Many pergolas, patio covers and carports need a permit. Use this checklist to get your paperwork together before you order.
Freestanding and cantilever aluminum carports for one or two vehicles.

Key things to decide before you order.
Allow about 10 to 12 ft of width per car and a length a few feet longer than your longest vehicle so doors open freely.
Flat-roof carports use a post at each corner. Cantilever models keep one side open for easier parking and a cleaner look.
Loads depend on span and post spacing. Check the typical ratings on each product against your local requirements before you order.
Posts anchor to a sound slab or new concrete footings. Most cities want a permit and a site plan with setbacks.
Measure the driveway and check clearance for tall vehicles with our size guide. Carports usually need a permit, so our install and permit guide walks through footings, setbacks and the documents we can provide. Comparing carports with patio covers for a side yard? Compare structures to see which fits.
Quick answers about sizing, installation and delivery.
Ratings depend on size and post spacing. Each product lists typical load information, and our team can confirm whether a size suits your area before you order.
Posts need a solid anchor: an existing slab in good condition or new concrete footings. Your local code sets the footing size and depth.
Patio covers are designed to attach with a wall hanger or ledger. Carports are freestanding. Either way, check the wall or roofline with a contractor if you are unsure it can carry the load.
Orders ship by freight to your driveway in the lower 48. The carrier calls ahead to schedule a delivery window.
Warranty terms depend on the product and component. We confirm the applicable manufacturer coverage with your order; contact us with your product and order details for help.
Available payment methods and any installment options are shown before you place your order. Contact our team about payment arrangements for a project quote.
