It depends. Whether pergola or trellis needs a permit in Unincorporated Coles County comes down to the details of your project.
Illinois has no statewide list of work exempt from a residential permit, so each municipality or county decides whether an open pergola needs one. Adding a solid or louvered roof, attaching the pergola to the house, or running power to lights or fans makes a permit much more likely under local codes. Zoning setbacks and lot coverage rules usually apply even where no building permit is needed.
