Codes, exemptions & field inspections

Build to the adopted code. Verify every exception.

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

The code baseline for Otsego County.

Michigan statewide codes applicable in 2026: 2021 Michigan Building Code for commercial/nonresidential work (effective April 9, 2025); 2015 Michigan Residential Code for one- and two-family dwellings remains current while the proposed 2021 residential update is stayed; 2021 Michigan Mechanical Code and 2021 Michigan Plumbing Code (effective March 12, 2024); 2023 National Electrical Code with Michigan amendments (effective March 12, 2024); and current Michigan energy and rehabilitation code provisions. The county webpage still labels its handouts as 2015 residential/building code references.

Inspection lane

Give at least 24 hours' notice by calling (989) 731-7400, selecting option 1 for Building, then option 1 to schedule. Provide the permit number, property address, inspection type, requested date, and point-of-entry instructions. Building inspections are Monday-Friday; electrical, mechanical, and plumbing inspections are Tuesday and Thursday. Requests must be received by 8:30 a.m. on the requested date. Do not cover work before approval; missed inspections can cause extra excavation/removal costs and delay the Certificate of Occupancy.

Minor-work playbook

Understand what may be exempt—and what is not.

The county application lists work commonly exempt from a building permit: painting, papering, tiling, carpeting, cabinets, countertops and similar finish work; one-story detached accessory structures up to 200 square feet; above-ground prefabricated pools under 24 inches deep and no more than 5,000 gallons; grade-level water tanks up to 5,000 gallons meeting the height-to-width limit; sidewalks and driveways no more than 30 inches above adjacent grade and not over a basement/story; swings and similar playground equipment; qualifying window awnings; and decks up to 200 square feet and no more than 30 inches above grade, subject to code conditions. Exempt work must still comply with applicable laws and ordinances.

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

Keep the work visible at every release point.

  1. 1

    Request with lead time

    Give at least 24 hours' notice by calling (989) 731-7400, selecting option 1 for Building, then option 1 to schedule.

Building inspections are Monday-Friday; electrical, mechanical, and plumbing inspections are Tuesday and Thursday. Requests must be received by 8:30 a.m. on the requested date.

  3. 3

    Close the record

    Retain the approved plans, inspection approvals, correction responses, and final certificate or occupancy release with the property file.

Contractor verification

Verify the builder before the contract is signed.

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

Keep the parcel rules beside the building plans.

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.

Which codes and exemptions should I review?

Michigan statewide codes applicable in 2026: 2021 Michigan Building Code for commercial/nonresidential work (effective April 9, 2025); 2015 Michigan Residential Code for one- and two-family dwellings remains current while the proposed 2021 residential update is stayed; 2021 Michigan Mechanical Code and 2021 Michigan Plumbing Code (effective March 12, 2024); 2023 National Electrical Code with Michigan amendments (effective March 12, 2024); and current Michigan energy and rehabilitation code provisions.

Exempt work must still comply with applicable laws and ordinances.

Field sequencing matters

The inspector needs to see the work at the right moment.

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.
