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 Leelanau County.

Leelanau County Building Safety reviews and issues building, electrical, plumbing, and mechanical permits under the current Michigan Construction Code. Current Michigan codes include the 2021 Michigan Building Code and 2021 Michigan Rehabilitation Code (effective April 9, 2025), 2015 Michigan Residential Code, 2021 Michigan Mechanical and Plumbing Codes (effective March 12, 2024), 2021 Michigan Commercial Energy Code (effective April 22, 2025), and 2023 Michigan Electrical Code/NEC (effective March 12, 2024). Land-use permits remain the responsibility of the applicable township or village.

Inspection lane

Call 231-256-9806 at least 24 hours before the inspection. Required stages include open footings, foundations before backfill, underground piping/ducts before covering, rough frame after rough trades and before insulation, and final building after plumbing, heating, and electrical approvals. A Certificate of Occupancy is required before occupancy, and the permit/address must be posted before construction.

Minor-work playbook

Understand what may be exempt—and what is not.

The county's materials defer ordinary building-permit exemptions to the Michigan code, including ordinary repairs that do not affect structural members, required egress, regulated plumbing, electrical, mechanical, or public-safety systems. One township ordinance cited in the county materials exempts an accessory structure of 100 square feet or less unless it is on a permanent foundation; verify the local zoning rule before relying on it. Architect/engineer seal exceptions for qualifying small one- and two-family dwellings also apply under state law.

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 231-256-9806 at least 24 hours before the inspection. Required stages include open footings, foundations before backfill, underground piping/ducts before covering, rough frame after rough trades and before insulation, and final building after plumbing, heating, and electrical approvals. A Certificate of Occupancy is required before occupancy, and the permit/address must be posted before construction.

  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.

N/A; the county publishes application requirements and inspection notice rules but no standard plan-review timeline

How are inspections scheduled?

Call 231-256-9806 at least 24 hours before the inspection. Required stages include open footings, foundations before backfill, underground piping/ducts before covering, rough frame after rough trades and before insulation, and final building after plumbing, heating, and electrical approvals. A Certificate of Occupancy is required before occupancy, and the permit/address must be posted before construction.

Which codes and exemptions should I review?

Leelanau County Building Safety reviews and issues building, electrical, plumbing, and mechanical permits under the current Michigan Construction Code. Current Michigan codes include the 2021 Michigan Building Code and 2021 Michigan Rehabilitation Code (effective April 9, 2025), 2015 Michigan Residential Code, 2021 Michigan Mechanical and Plumbing Codes (effective March 12, 2024), 2021 Michigan Commercial Energy Code (effective April 22, 2025), and 2023 Michigan Electrical Code/NEC (effective March 12, 2024). Land-use permits remain the responsibility of the applicable township or village. The county's materials defer ordinary building-permit exemptions to the Michigan code, including ordinary repairs that do not affect structural members, required egress, regulated plumbing, electrical, mechanical, or public-safety systems. One township ordinance cited in the county materials exempts an accessory structure of 100 square feet or less unless it is on a permanent foundation; verify the local zoning rule before relying on it. Architect/engineer seal exceptions for qualifying small one- and two-family dwellings also apply under state law.

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.
