Do I need a permit for pergola or trellis in Unincorporated Vigo County?
It depends. Whether pergola or trellis needs a permit in Unincorporated Vigo County comes down to the details of your project.
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. Indiana's residential code deletes the IRC's permit, exemption, inspection, and fee sections (R105 and R108 to R114), so whether this job needs a permit is set by the local ordinance of the city, town, or county, not by the model IRC exemption list. Under Indiana's Section R309.6, detached accessory structures must be constructed to applicable sections of the residential code unless Table R309 says otherwise, so the local office may review a pergola as an accessory structure, especially one with a louvered or solid roof. Indiana's residential code states that appendix provisions are not enforceable unless specifically adopted, so ask the local office which rules it applies to pergolas and patio covers.
