Do you need a permit for a patio cover installation? in Verenigde Staten
Sometimes. A patio cover (solid roof extension, alumawood, or attached pergola with a roof) may or may not require a permit depending on size, whether it's attached to the house, and local zoning setback rules. Attached structures almost always need permits; freestanding covers under local size thresholds may be exempt.

Country-specific detail
In the US, most jurisdictions require permits for attached patio covers because they impose lateral and gravity loads on the house structure. Freestanding patio covers under approximately 200 sq ft (varies by jurisdiction — some use 120 sq ft) may be exempt from permit requirements but still must meet setback rules. The IRC requires engineering for wind and snow loads, proper footing depths, and ledger board attachment details (lag bolts into rim joist, flashing). Adding electrical for ceiling fans or lights triggers a separate electrical permit. HOA architectural approval may also be required.
