Remodeling Permits in Michigan: What You Actually Need
Remodeling permits get treated as red tape by people who have never seen what unpermitted work looks like when a wall comes down twenty years later. They are not a formality. They are the only independent check that somebody other than the person being paid has looked at the work.
Here is which permits a project pulls, who should apply for them, what the inspector is actually looking at, and what happens when work was done without any of it.
Which remodeling permits a project actually pulls
Residential construction in Michigan is governed by the Michigan Residential Code, and permits are issued and inspected by your local building department. In municipalities that do not administer code enforcement themselves, the state Bureau of Construction Codes does it instead, so the first practical question is simply which office covers your address.
Most remodeling projects pull some combination of four permits, each with its own inspections:
- Building. Structural work, framing, wall removal, additions, egress openings, decks.
- Electrical. New circuits, altered wiring, panel work, added devices and fixtures.
- Mechanical. Heating, cooling, ductwork, ventilation, gas piping.
- Plumbing. New or relocated fixtures, drainage, venting, water supply.
A basement finish is the clearest example: it typically pulls all four at once, which is one reason it takes longer than its square footage suggests.
What generally does not need a permit
Cosmetic work is usually exempt. Painting and wallpapering. Flooring over an existing subfloor. Replacing cabinet doors or countertops without moving plumbing. Swapping a light fixture for another in the same location. Replacing a faucet or a toilet in the same position.
The grey area is wider than people expect. Replacing a window in the existing opening may be exempt, while enlarging that opening is not. Replacing a water heater usually needs a permit, although homeowners rarely realise it. Replacing a deck board is maintenance, rebuilding the deck structure is not. When you are unsure, call and ask. Building departments answer that question all day and they would rather answer it than fail an inspection.
Zoning is the check that can stop a project on day one
Zoning is separate from building code and it runs first on anything that changes the footprint. Setbacks from property lines, maximum lot coverage, height limits, easements and, in some neighbourhoods, private covenants can all restrict where a structure may go before any code question is asked.
This is why an addition should be checked against zoning before anyone falls in love with a footprint. Finding out at design stage that the addition cannot go where you pictured it is inconvenient. Finding out after paying for drawings is expensive.
Who should pull the permit, and why it should not be you
The licensed contractor performing the work should apply for the permit in their own name. That is the arrangement the licensing system assumes.
Michigan does allow homeowners to pull permits for work on their own homes in defined circumstances, and that provision exists for people actually doing the work themselves. Using it to cover work a contractor is performing shifts responsibility onto you: for compliance, for the inspection outcome, and for anything discovered later.
If a contractor asks you to pull the permit, ask why. The answers are usually that they are unlicensed, uninsured, or would rather not have their name attached to the record. The permit responsibility clause belongs in the contract, in writing. Everything in the work we take on is permitted under the builder's licence, which is the ordinary arrangement rather than a selling point.
What the inspector is actually checking
Inspections happen at fixed points in the sequence, and the pattern is consistent: anything that will be covered gets inspected before it is covered.
A footing inspection before concrete. A framing inspection once the structure is up and before insulation. Rough electrical, mechanical and plumbing inspections while everything is still open, sometimes combined into one visit. An insulation inspection before drywall in many jurisdictions. Then final inspections on each trade once the work is complete.
The inspector is checking structural adequacy, fire and life safety, and the parts of the installation that become invisible. In a basement, egress requirements are the usual sticking point, along with ceiling height, smoke and carbon monoxide alarms, and combustion air for any appliance sharing the space.
How permits affect your schedule
Two ways, and both are worth planning around.
At the front, review time. A single-trade permit for simple work may be issued quickly. An addition with a plan review and a zoning check can take weeks. That time is the department's, not your contractor's, and no amount of urgency changes it.
During construction, hold points. Work stops at each inspection until it passes. Inspections are scheduled, not summoned, and a single day of slippage can cost a week if it pushes past the next availability of a subcontractor booked around three other trades. Our guide on where permits sit in the schedule puts both effects in context.
A failed inspection is usually not a disaster. Most are corrections rather than condemnations: something needs a fastener, a clearance, or a detail added, and the reinspection follows quickly.
What happens if work was done without a permit
Plenty of West Michigan houses contain unpermitted work, most of it done by previous owners with good intentions. The recurring examples are a finished basement with no record, a bathroom added with no venting, a deck with undersized footings, and wiring extended without ground or fault protection.
The consequences are real but rarely immediate. At sale, an inspector finds it, an appraiser may exclude unpermitted finished area from the valuation, and a buyer uses it to renegotiate. On an insurance claim, unpermitted work can complicate a settlement. And on your next project, a contractor opening a wall finds it and cannot in good conscience build over it.
The right response is assessment rather than concealment. Much of it can be brought into compliance through a permit now, sometimes with modest correction work. If you have found something in your own house and do not know how serious it is, ask us what your project needs and we will tell you honestly whether it is a safety problem or a paperwork one.
Frequently asked questions
Do I need a permit to remodel a bathroom or kitchen?
Almost always, if anything beyond finishes is changing. Moving or adding plumbing, altering electrical, changing ventilation, removing or altering a wall, and structural work all require permits. Purely cosmetic work such as painting, replacing cabinet doors, or swapping a light fixture for one in the same location generally does not. The reliable test is whether anything behind the surface is being changed.
Who applies for the permit, me or the contractor?
The licensed contractor doing the work. When a homeowner pulls the permit, they take on responsibility that was meant to sit with the licensed builder, including responsibility for the work passing inspection. If a contractor asks you to pull it, the usual explanations are that they are not licensed, not insured, or trying to keep their name off the record. Any of the three is a reason to stop.
How long does permit review take in Michigan?
It varies by municipality and by project. A single-trade permit for straightforward work is often issued quickly. A structural addition with zoning review takes considerably longer, sometimes weeks, particularly where a plan review or a zoning board decision is involved. Ask your building department at the start rather than assuming, and build the answer into the schedule rather than hoping.
What happens if I find unpermitted work in a house I already own?
Do not panic and do not cover it back up. Have it assessed by someone competent, because the real question is whether it is unsafe rather than whether it is on file. Common findings are wiring without ground or fault protection, a removed wall with no header, or a bathroom added with no venting. Many can be brought into compliance through a permit now, and doing so protects you at sale and on any insurance claim.
Will unpermitted work cause a problem when I sell?
It can. Buyers' inspectors find it, appraisers may exclude unpermitted finished area from the valuation, lenders can baulk, and buyers use it to renegotiate. A finished basement with no permit record is one of the most common examples. Resolving it before listing is almost always easier than resolving it during a transaction with a deadline attached.
