Codes, exemptions & field inspections
This guide translates the available agency record into a preconstruction checklist for structural scope, minor work, and inspection release. The adopted code and the issuing official control when a field condition is disputed.
Regulatory framework
Michigan statewide construction codes administered by the county: 2021 Michigan Building Code; 2015 Michigan Residential Code; 2021 Michigan Rehabilitation Code; 2021 Michigan Mechanical and Plumbing Codes; 2021 Michigan Commercial Energy Code; and 2023 Michigan Electrical Code/NEC with Michigan amendments. Plainfield Township is the listed local building jurisdiction; the county handles the other listed Iosco County units.
Inspection lane
Call (989) 362-6511 to request inspections and provide the permit number and exact job-site location. The county requests 24 hours' notice before a footing concrete pour and its handout requests three working days' notice generally. Inspection days listed are Monday-Thursday for building, Wednesday/Saturday for electrical, and Wednesday for plumbing/mechanical; final occupancy inspection requires the project to be complete and all trades approved.
Minor-work playbook
Iosco County requires permits for all new commercial and residential construction, including pools, decks, carports, and sheds over 200 square feet. The department states that roofing and siding permits are no longer required within its jurisdiction. Ordinary repairs that do not affect structural members, required egress, or regulated systems may also qualify for Michigan-code exemptions; confirm with the department and municipality because zoning and septic approvals can still be required.
Field rule
A permit exemption generally addresses one narrow construction trigger. It does not automatically waive zoning, land-use, floodplain, shoreline, fire, energy, electrical, utility, septic, or right-of-way requirements. Obtain written confirmation when the project involves a new structure, structural alteration, change in occupancy, or concealed work.
Inspection pipeline
Request with lead time
Call (989) 362-6511 to request inspections and provide the permit number and exact job-site location. The county requests 24 hours' notice before a footing concrete pour and its handout requests three working days' notice generally. Inspection days listed are Monday-Thursday for building, Wednesday/Saturday for electrical, and Wednesday for plumbing/mechanical; final occupancy inspection requires the project to be complete and all trades approved.
Preserve access
Do not cover framing, reinforcement, wiring, piping, damp-proofing, or life-safety work until the required inspection has been completed and documented.
Close the record
Retain the approved plans, inspection approvals, correction responses, and final certificate or occupancy release with the property file.
Contractor verification
Use the state licensing system to verify active registration, trade credentials, bond status, and liability coverage where available. Match the legal business name to the proposal and permit application.
Planning reference
A building permit is only one part of statutory compliance. Check the local zoning, ordinance, map, or land-use reference before finalizing setbacks, height, lot coverage, access, drainage, or accessory structure placement.

Field sequencing matters
Code compliance is not only a plan-review exercise. Footings, reinforcement, framing, fireblocking, wiring, piping, insulation, weather protection, and life-safety systems each have points where the work must remain accessible. Build the inspection calendar into the trade schedule instead of treating it as a final administrative step.
When a project qualifies for a narrow minor-work exemption, keep a written explanation of why it qualifies and confirm that related zoning, utility, fire, energy, or environmental rules do not create a separate approval requirement.
Closeout file
Keep the approved plan set, inspection approvals, correction responses, contractor license verification, final certificate, and any occupancy release together. A clean record protects the owner, builder, lender, insurer, and future buyer.
