Which codes and exemptions should I review?
Ionia County lists the 2021 Michigan Building Code for commercial work, 2021 Michigan Plumbing Code, 2021 Michigan Mechanical Code, 2023 National Electrical Code with Michigan Part 8 amendments, and 2015 Michigan Residential Code. The county administers these codes for the county jurisdiction; the City of Portland independently enforces them. Minor ordinary repairs that do not affect structural members, required egress, or regulated plumbing, electrical, mechanical, public-health, or general-safety systems may be exempt under Michigan code; verify with the building official. The county publishes a Notice Regarding Construction of Agricultural Building for qualifying agricultural exemptions. Construction-document seals are not required for one- and two-family dwellings under 3,500 square feet or public works under $15,000, but that is a plan-submittal exception rather than a general permit exemption.
