Kentwood is the third of the Kent County jurisdictions in this series, sitting between Grand Rapids and the county’s southern townships. Its most useful feature for anyone working across Michigan is that it does something most cities do not: it publishes the edition it enforces for each code part, on one page.
Electrical, mechanical, plumbing and roofing permits can be applied for online. Building permits and pool permits cannot: those go to the office on Breton Avenue with the application, the plans and the plan review fee together.
This guide covers work inside the Kentwood city limits. Grand Rapids, Wyoming and the other Kent County communities permit separately, and a Grand Rapids postal address does not settle which city a parcel is in.
Kentwood publishes the split, and it is stark. The city’s enforced codes page lists commercial building work under the twenty twenty-one Michigan Building Code while residential building, electrical, plumbing and mechanical work all sit under the two thousand fifteen Michigan Residential Code. Two projects on the same street, one commercial and one residential, are reviewed against editions six years apart.
What requires a building permit in Kentwood?
Michigan builds on a single statewide construction code adopted under the Stille-DeRossett-Hale Single State Construction Code Act (1972 PA 230) and administered by the Bureau of Construction Codes within the Department of Licensing and Regulatory Affairs. The state code adopts International Code Council model codes with Michigan amendments, but it adopts them part by part on separate effective dates — the building and rehabilitation parts, the plumbing part, the mechanical part and the electrical part each move on their own schedule. Local units may amend only to make the code more restrictive, never less, and local amendments are filed with the bureau. So the first question in Kentwood is which authority holds the code for the parcel and which edition governs each part of the work.
Permit required
- New commercial, multi-family and residential construction, additions and change of occupancy
- Structural alterations, load-bearing changes, foundations, decks and retaining walls
- Electrical work — services, panels, circuits, solar and EV charging — under the electrical part of the state code and the referenced National Electrical Code
- Plumbing and gas work under the plumbing part of the state code, pulled by a state-licensed plumber
- Mechanical and HVAC change-outs, and work affecting the energy code envelope
- Re-roofing above the exempt scope, pools, signs, and demolition
Often exempt
- Minor repairs and maintenance replacing materials in kind
- Small accessory structures below the code threshold, where zoning allows
- Painting, flooring, cabinetry and other finish work
- Like-for-like fixture or appliance swaps with no alteration to wiring or piping
Local amendments, fee schedules and the choice of third-party agency differ from one municipality to the next, so an exempt list from a neighbouring township is not reliable. An exemption from a building permit is never an exemption from zoning, the energy code, or an electrical or plumbing permit. Confirm scope with Kentwood Inspections before work starts.
The statewide layers that apply everywhere
Two Michigan features catch projects owners assume are simple. First, enforcement runs down a three-tier ladder: the local unit of government administers and enforces the act and the code; where it declines to, the county may give notice that it will; and where neither does, the bureau’s director assumes responsibility for that unit. Unlike states where the county never issues a building permit, a Michigan county can be the authority having jurisdiction outright. Second, licensing is statewide, not local: residential builders and maintenance and alteration contractors are licensed by the state, as are the plumbing, electrical and mechanical trades, and the permit application itself must carry the licence number and its expiry date. The residential part in particular has not moved in step with the commercial parts, so a house and a shop on the same street can be reviewed against editions years apart — confirm the edition in force for each part on your filing date. Great Lakes and inland floodplain administration applies along the state’s shorelines and rivers, and snow loading is a live structural constraint. The filing route splits too. Electrical, mechanical, plumbing and roofing permits are available online, but building permits and pool permits must be submitted to the office at Breton Avenue with the application, plans and plan review fee together. Permits applied for outside business hours are processed on the next business day.
Who handles permitting in Kentwood?
The Inspections team enforces codes for building, electrical, mechanical, plumbing, property maintenance, rental programmes and signs, covering both new construction quality and the condition of existing structures and exterior property.

| Contractor access | First-time portal users need a web pin from the office; homeowners do not |
Access to the online system differs by applicant. Contractors using it for the first time in Kentwood need a web pin, obtained by contacting the office during business hours. Homeowners need neither a web pin nor an account to apply for a permit, which makes the homeowner route unusually low-friction here.
Inspectors are reachable directly only in two windows a day, from half past seven to nine in the morning and from half past three to four in the afternoon, Monday to Friday, and the permit holder is asked to call twenty-four hours before the inspection is needed. Between those windows the route is the main office line or email.
Permit types
Residential permits
Residential building work in Kentwood is reviewed against the residential code, which the city lists as covering the residential electrical, plumbing and mechanical work as well. Building and pool permits are filed in person with the plans and plan review fee; the other trades can be filed online. Concealed work must be inspected before being covered.
How Michigan contractor credentials work
Michigan does license at state level, and the licence is the substantive credential rather than a registration. Residential builders and maintenance and alteration contractors are licensed under Article 24 of Public Act 299 of 1980, administered by the Bureau of Construction Codes, and the plumbing, electrical and mechanical trades are licensed by the state as well. A state licence is valid across the whole of Michigan; what does not travel is the local permit, fee schedule and inspection route.
The licence number goes on the permit application. Michigan requires the application to set out the licence number and expiry date of the residential builder, maintenance and alteration contractor, architect or engineer acting for the owner, together with a written instrument — a contract, power of attorney or letter of authorisation — showing that person is authorised to act. Doing residential work that requires a licence without one is a civil violation, which the county prosecuting attorney or the Attorney General may pursue. Confirm what Kentwood Inspections requires for the parcel, along with insurance coverage.
Commercial permits
Commercial work is reviewed against the twenty twenty-one building, plumbing and mechanical parts and the twenty twenty-three national electrical code with the state Part Eight changes, with the rehabilitation code applying to existing buildings and the property maintenance code to condition. Confirm each part at your filing date rather than assuming a single edition.
Licenses, trade classifications and design professionals
Practically, three credential layers appear on Michigan projects: the state residential builder or maintenance and alteration licence on residential work; separately licensed electrical, plumbing and mechanical trades, also licensed by the state; and, on commercial and larger residential work, drawings sealed by a Michigan-licensed architect or professional engineer, with a licensed plan reviewer required on commercial work above defined thresholds. Confirm what Kentwood Inspections requires for the specific building before filing.
Kentwood permit costs and fees
Kentwood permit fees follow the published schedules by permit type, with the plan review fee due at submission for building and pool permits. Rental inspection fees are charged per unit, with separate re-inspection, missed appointment and expired certification charges.
| Fee component | How it works |
|---|---|
| Building permit | Based on project valuation or square footage; set by the local unit, the county, or the state where it is the authority |
| Plan review | A percentage of the permit fee or a flat charge; commercial work above defined thresholds needs a licensed plan reviewer |
| Trade permits | Separate electrical, plumbing and mechanical fees under the local schedule |
| State construction code fee | The statutory state fee collected with the permit under the construction code act |
| Zoning and use | Zoning, use-and-occupancy and, in some places, contractor-licence fees |
| Re-inspections and revisions | Additional fees for failed inspections, revisions and expired permits |
Michigan fees are set by whoever holds enforcement for the parcel — the local unit, the county, or the state where neither has taken it on — so the schedule follows the authority rather than the state. A figure from a neighbouring municipality is not reliable, and a figure from a neighbouring township can be wrong even where the county enforces both. Ask Kentwood Inspections for the schedule in force on your filing date.

Trade permits and who may pull them
Trade permits are separate from the building permit and, on projects that require one, generally cannot be issued until the building permit is in place. Each trade follows its own part of the state construction code, and is tied to a contractor holding the relevant state licence — which, unlike a municipal credential, is portable across the whole of Michigan.
Michigan licenses the trades at state level. Electrical, plumbing and mechanical contractors hold licences issued by the state, valid anywhere in Michigan, and residential builders and maintenance and alteration contractors are licensed the same way. What varies by parcel is not the licence but the permit, the fee and the inspection route. Performing residential work that requires a licence without holding one is a civil violation the county prosecutor or the Attorney General may act on.
- Electrical work follows the electrical part of the state code and the referenced National Electrical Code, under a state-licensed electrical contractor.
- Plumbing work follows the plumbing part of the state code, under a state-licensed master or journeyman plumber.
- Mechanical work follows the mechanical and energy parts of the state code, under a state-licensed mechanical contractor.
Permit required
- Service installations, panel upgrades, new circuits, solar PV and EV chargers
- New plumbing, repipes, water heater change-outs, fixtures, backflow and gas piping
- HVAC installation and change-out, ductwork, venting and commercial kitchen exhaust
- Sprinkler, standpipe and fire alarm work on commercial and multi-family structures
Typically exempt
- Replacing a fixture, switch, receptacle or light with no alteration to wiring or piping
- Clearing a stoppage without replacing or rearranging concealed piping
- Filter, thermostat and routine component service
- Like-for-like appliance repair that does not alter the connection
How to apply for a Kentwood building permit
Kentwood publishes the edition it enforces for each code part, and the commercial and residential positions differ materially.
First-time portal users need a web pin from the office during business hours. Homeowners need neither pin nor account.
Electrical, mechanical, plumbing and roofing go online. Building and pool permits go to the Breton Avenue office with plans and the plan review fee.
Permits applied for outside business hours are processed on the next business day, so a late filing does not gain a day.
Inspectors are directly reachable from half past seven to nine and half past three to four, Monday to Friday.
The permit holder should call twenty-four hours before the inspection, and concealed work must be inspected before it is covered.
Review, corrections and what actually causes delay
In Michigan, the first cause of delay is uncertainty over who enforces the code — filing with the local unit when the county holds enforcement for it, or with the county when the state does. After that comes the edition question, because the building, plumbing, mechanical and electrical parts moved on different dates and a submission drawn to the wrong one is a correction cycle. Then a missing or expired state licence number on the application, energy-code and plan documentation, and floodplain requirements along the shorelines and rivers. Build the plan-review time into the schedule and confirm the checklist with Kentwood Inspections before filing.
Approvals do not stay live indefinitely. A Michigan building permit carries a validity period and can expire if work does not start or stalls between inspections. On phased or financed work, keep the permit active with periodic progress inspections and confirm the expiry window before it passes.
Inspections in Kentwood
Where a permit is required, standard checkpoints include footing and foundation, framing, rough-in electrical, plumbing and mechanical, insulation and energy-code compliance, fire systems on commercial work, and final, with a use-and-occupancy certificate before the building is used. Rental dwellings are inspected against the property maintenance code and need a certificate of compliance, with fees charged per unit and separate charges for re-inspection and missed appointments.
Michigan inspections are keyed to the code edition in force when the permit issued — which, because editions are adopted part by part, can differ between the building inspection and the trade inspections on the same job. They are carried out by an inspector certified by the bureau, employed or contracted by whichever authority holds enforcement for the parcel. Keep the approved plans and the energy-code documentation on site for the inspector to check against, and confirm the notice Kentwood Inspections needs and its inspection windows.
Do not cover work before the required inspection has been approved. Keep the issued permit, the approved plans, product listings, energy-code documentation and your correction responses available on site.
Kentwood permit search and official resources
Permit records in Michigan sit with the authority that issued them — the local unit, the county, or the state bureau where neither took enforcement on. Where Kentwood Inspections is the authority for the City of Kentwood, it holds the building permit, the inspection history and the use-and-occupancy certificate. If you are buying, refinancing or renovating, confirm that past work was permitted rather than assuming it was — open permits and missing certificates are a common closing problem.
Confirm the authority having jurisdiction first, then confirm the edition. Michigan enforces one statewide construction code, but enforcement may sit with the local unit, the county or the state, and the code is adopted part by part on separate effective dates. Both questions have to be answered for the parcel and the filing date before the requirements are knowable.

Frequently asked questions
Why are commercial and residential on different code editions here?
Because Michigan adopts the code part by part, and Kentwood publishes the result. Its enforced codes page lists commercial building work under the twenty twenty-one Michigan Building Code and residential building, electrical, plumbing and mechanical work under the two thousand fifteen Michigan Residential Code. One Michigan point catches almost everyone: the commercial and residential codes are not on the same edition. The bureau moved the building and rehabilitation parts to their two thousand twenty-one editions on the ninth of April, two thousand twenty-five, and the plumbing, mechanical and electrical parts moved on their own two thousand twenty-four dates. The residential code did not move with them. Replacement residential rules were filed for an August two thousand twenty-five effective date, but the Court of Claims entered a stipulated order stopping the department from implementing them while a builders’ association challenge is litigated, so the bureau still lists the two thousand fifteen Michigan Residential Code as the code in force. That case was still live when this guide was written. Confirm the edition governing each part of your work on your filing date rather than assuming the newest one applies.
Can I apply for my building permit online?
No. Electrical, mechanical, plumbing and roofing permits can be applied for online, but building permits and pool permits must be submitted to the office on Breton Avenue with the application, the plans and the plan review fee together.
What is a web pin and do I need one?
Contractors using the online system for the first time in Kentwood need a web pin, obtained by contacting the office during business hours. Homeowners need neither a web pin nor an account to apply for a permit.
When can I speak to an inspector?
Inspectors are reachable by phone between half past seven and nine in the morning and between half past three and four in the afternoon, Monday to Friday. The permit holder should call twenty-four hours before the inspection is needed.
Do I need a rental certificate of compliance?
Rental dwellings must be registered and must pass a rental inspection against the property maintenance code to receive a certificate of compliance. Fees are charged per unit, with separate re-inspection and missed appointment charges and higher administrative charges where a certification has expired.
Who licenses the contractor?
The state, not the city. Residential builders and maintenance and alteration contractors are licensed by the state under Article 24 of Public Act 299 of 1980, administered by the Bureau of Construction Codes, and the plumbing, electrical and mechanical trades are state-licensed as well. The licence is valid statewide. The permit application must set out the licence number and its expiry date, and performing residential work that requires a licence without holding one is a civil violation the county prosecuting attorney or the Attorney General may pursue.
