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 Sanilac County.

Michigan LARA's statewide jurisdiction list revised July 29, 2026 lists Sanilac County as County for building, electrical, mechanical, and plumbing enforcement throughout the county. The current Michigan framework includes the 2021 Michigan Building Code, 2015 Michigan Residential Code for one- and two-family dwellings while the proposed 2021 residential update is stayed, 2021 Michigan Mechanical and Plumbing Codes, 2023 National Electrical Code with Michigan amendments, and current Michigan energy and rehabilitation provisions. Plumbing, electrical, and mechanical permits must conform to the Michigan Energy Code.

Inspection lane

The permit holder schedules inspections by calling (810) 648-4664 Monday-Friday, 8:00 a.m.-4:30 p.m. Requests must include the permit number, permit type, permit holder name, construction-site address, city/village/township, and a daytime contact phone. Building, plumbing, mechanical, and electrical projects require periodic inspections; concealed work must not be covered before approval, and re-inspection fees may apply.

Minor-work playbook

Understand what may be exempt—and what is not.

No complete county exemption list was published. The department's procedures identify replacement equipment as an exception allowing installation before permit issuance only when the permit application and inspection request are made within two days after installation or before the equipment is concealed. Otherwise, verify whether ordinary repairs or cosmetic finish work are exempt under the applicable Michigan code before starting.

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.

  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; no fixed county review timeline was published. Complete plans, zoning approval, scaled site plan, and required supporting documents must be submitted before issuance; the department requires framing details for review.

Building, plumbing, mechanical, and electrical projects require periodic inspections; concealed work must not be covered before approval, and re-inspection fees may apply.

Which codes and exemptions should I review?

Michigan LARA's statewide jurisdiction list revised July 29, 2026 lists Sanilac County as County for building, electrical, mechanical, and plumbing enforcement throughout the county. The current Michigan framework includes the 2021 Michigan Building Code, 2015 Michigan Residential Code for one- and two-family dwellings while the proposed 2021 residential update is stayed, 2021 Michigan Mechanical and Plumbing Codes, 2023 National Electrical Code with Michigan amendments, and current Michigan energy and rehabilitation provisions.

The department's procedures identify replacement equipment as an exception allowing installation before permit issuance only when the permit application and inspection request are made within two days after installation or before the equipment is concealed. Otherwise, verify whether ordinary repairs or cosmetic finish work are exempt under the applicable Michigan code before starting.

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.
