It depends. Whether pergola or trellis needs a permit in Unincorporated Crawford County comes down to the details of your project.
Missouri has no statewide residential building code; whether a permit is required depends entirely on the city or county code that covers the address. Missouri has no statewide rule for pergolas or arbors; a local code decides, and an attached pergola or one with a solid or louvered roof is more likely to need a permit. Many rural Missouri counties have not adopted a county building code, and a county code applies only outside city limits; inside a city, the city's own code governs. A solid, waterproof or louvered roof turns an open pergola into a roofed structure, which departments generally review like a patio cover, with attention to roof framing and wind loads. An open lattice or rafter pergola is the version most often treated as minor, so if you are comparing designs, ask your department how it treats each one before you buy a kit.
