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 Arenac County.

Current Michigan codes identified by LARA for 2026: 2021 Michigan Building Code (effective April 9, 2025); 2015 Michigan Residential Code (current code, effective February 8, 2016, with later 2021 residential rules held by court order); 2021 Michigan Rehabilitation Code; 2021 Michigan Mechanical Code; 2021 Michigan Plumbing Code; 2023 National Electrical Code/Michigan Electrical Code (effective March 12, 2024); and 2021 Michigan Commercial Energy Code (effective April 22, 2025). Arenac's revised June 2025 application separately identifies Michigan Residential Code/Michigan Building Code review cycles and requires separate electrical, mechanical and plumbing applications.

Inspection lane

Call 989-846-9791 when ready and provide the permit number, site address and access instructions; the applicant is responsible for requesting every inspection. Normal inspection days are building Thursday, electrical Tuesday, and mechanical/plumbing Tuesday, generally between 8:00 a.m. and 6:00 p.m.; other days may be arranged if available. An unclear road address can cause an additional inspection fee.

Minor-work playbook

Understand what may be exempt—and what is not.

Michigan code exemptions include one-story detached tool/storage sheds or playhouses up to 120 square feet, fences up to 7 feet, retaining walls up to 4 feet unless supporting a surcharge or impounding regulated liquids, grade-level water tanks up to 5,000 gallons, certain low sidewalks and driveways, painting/papering/tiling/carpeting/cabinets/countertops and similar finish work, qualifying above-ground pools under 24 inches deep, agricultural shade-cloth structures, playground equipment, qualifying window awnings, and specified movable fixtures. Ordinary repairs are exempt only when they do not affect structural supports, egress, regulated systems, public health or general safety. Arenac advises calling before starting because garages, sheds, pole barns, decks, porches, pools, additions and demolitions may require permits.

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

    Call 989-846-9791 when ready and provide the permit number, site address and access instructions; the applicant is responsible for requesting every inspection. Normal inspection days are building Thursday, electrical Tuesday, and mechanical/plumbing Tuesday, generally between 8:00 a.m. and 6:00 p.m.; other days may be arranged if available. An unclear road address can cause an additional inspection fee.

  2. 2

    Preserve access

    Do not cover framing, reinforcement, wiring, piping, damp-proofing, or life-safety work until the required inspection has been completed and documented.

  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.

No verified planning reference link is listed; ask the agency for the parcel-specific source.

Which codes and exemptions should I review?

Current Michigan codes identified by LARA for 2026: 2021 Michigan Building Code (effective April 9, 2025); 2015 Michigan Residential Code (current code, effective February 8, 2016, with later 2021 residential rules held by court order); 2021 Michigan Rehabilitation Code; 2021 Michigan Mechanical Code; 2021 Michigan Plumbing Code; 2023 National Electrical Code/Michigan Electrical Code (effective March 12, 2024); and 2021 Michigan Commercial Energy Code (effective April 22, 2025).

Arenac advises calling before starting because garages, sheds, pole barns, decks, porches, pools, additions and demolitions may require permits.

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.
