Do I need a permit for pergola or trellis in Unincorporated Marquette County?
It depends. Whether pergola or trellis needs a permit in Unincorporated Marquette County comes down to the details of your project.
Pergolas and arbors are not named on Michigan's list of work exempt from permit (R 408.30505); a freestanding one-story structure of 200 square feet or less may fall under the accessory structure exemption. A pergola attached to the house, larger than 200 square feet, or with a solid or louvered roof is more likely to need a building permit; confirm with the enforcing agency. Wiring for lights or fans needs an electrical permit regardless of the building exemption. Local zoning setbacks still apply to structures that are exempt from a building permit. 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.
