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 Alger County.

Current Michigan codes identified by the state LARA code-book page 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 (effective April 9, 2025); 2021 Michigan Mechanical Code and 2021 Michigan Plumbing Code (effective March 12, 2024); 2023 National Electrical Code/Michigan Electrical Code (effective March 12, 2024); and 2021 Michigan Commercial Energy Code (effective April 22, 2025).

Inspection lane

Do not start work or conceal installations before the permit and required inspections. The inspector's telephone number is provided on the permit; call with the job location, permit number and contact information, giving as much advance notice as possible. The county states that an inspection request is answered within two business days for scheduling and inspections are typically performed within five business days, subject to the schedule.

Minor-work playbook

Understand what may be exempt—and what is not.

Michigan's official permit guidance exempts ordinary repairs only when they do not cut away walls or structural supports, alter required means of egress, or affect regulated plumbing, gas, electrical, mechanical, public-health or general-safety work. Alger County's application also notes that sealed plan documents are generally not required for one- and two-family dwellings under 3,500 square feet and public works under $15,000; this is a plan-submission exception, not a blanket permit exemption. The county says all commercial work requires a permit and advises confirming any small accessory structure or cosmetic project with the Building Codes Inspector.

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

    Do not start work or conceal installations before the permit and required inspections. The inspector's telephone number is provided on the permit; call with the job location, permit number and contact information, giving as much advance notice as possible. The county states that an inspection request is answered within two business days for scheduling and inspections are typically performed within five business days, subject to the schedule.

  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.

Which codes and exemptions should I review?

Current Michigan codes identified by the state LARA code-book page 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 (effective April 9, 2025); 2021 Michigan Mechanical Code and 2021 Michigan Plumbing Code (effective March 12, 2024); 2023 National Electrical Code/Michigan Electrical Code (effective March 12, 2024); and 2021 Michigan Commercial Energy Code (effective April 22, 2025).

The county says all commercial work requires a permit and advises confirming any small accessory structure or cosmetic project with the Building Codes Inspector.

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.
