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 Oakland County.

Michigan's current State Construction Code applies countywide, with the 2021 Michigan Building Code and 2015 Michigan Residential Code as the principal building codes; current Michigan trade codes include the 2021 Mechanical and Plumbing Codes and 2023 Michigan Electrical Code/NEC. Oakland County's 2026 Statewide Jurisdiction List identifies no county program and shows local enforcement for the listed municipalities, so confirm the applicable local enforcing agency for the project address.

Inspection lane

Use the municipality's building department for local projects. For state-administered projects, the inspector phone is supplied on the permit; call with the job location, permit number, and contact information, giving advance notice. The state application says scheduling responds within two business days and inspections are typically performed within five business days, subject to the inspection schedule. No work may be concealed before inspection.

Minor-work playbook

Understand what may be exempt—and what is not.

Michigan LARA states that ordinary repairs do not require a building permit when they do not cut away walls or partitions, remove or alter structural beams or bearing supports, change required means of egress, or affect regulated plumbing, electrical, mechanical, public-health, or general-safety work. Municipal exemptions and zoning requirements may add local conditions.

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

    Use the municipality's building department for local projects. For state-administered projects, the inspector phone is supplied on the permit; call with the job location, permit number, and contact information, giving advance notice. The state application says scheduling responds within two business days and inspections are typically performed within five business days, subject to the inspection schedule. No work may be concealed before inspection.

  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.

Project questions

Frequently asked questions for Oakland County

Who handles permitting for this jurisdiction?

This record is marked Municipal Fallback. Confirm whether a city, state agency, or other local authority controls the parcel before filing.

How should I begin an application?

Begin with the online permit gateway listed in the application guide. If the portal does not recognize the address or project type, contact N/A countywide; Oakland County Planning, Zoning & Land Use: 248-858-4071; Michigan BCC permit questions: 517-241-9313.

How long might review take?

N/A for Oakland County because there is no county program and municipal review times vary. For state-administered inspections, scheduling responds within two business days and inspections are typically within five business days; this is not a plan-review guarantee.

How are inspections scheduled?

Use the municipality's building department for local projects. For state-administered projects, the inspector phone is supplied on the permit; call with the job location, permit number, and contact information, giving advance notice. The state application says scheduling responds within two business days and inspections are typically performed within five business days, subject to the inspection schedule. No work may be concealed before inspection.

Which codes and exemptions should I review?

Michigan's current State Construction Code applies countywide, with the 2021 Michigan Building Code and 2015 Michigan Residential Code as the principal building codes; current Michigan trade codes include the 2021 Mechanical and Plumbing Codes and 2023 Michigan Electrical Code/NEC. Oakland County's 2026 Statewide Jurisdiction List identifies no county program and shows local enforcement for the listed municipalities, so confirm the applicable local enforcing agency for the project address. Michigan LARA states that ordinary repairs do not require a building permit when they do not cut away walls or partitions, remove or alter structural beams or bearing supports, change required means of egress, or affect regulated plumbing, electrical, mechanical, public-health, or general-safety work. Municipal exemptions and zoning requirements may add local conditions.

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.
