In Kent County — West Michigan’s largest county, home to Grand Rapids — there is no county building department, and the State of Michigan BCC issues no permits here. Every city, village and township in the county has taken on enforcement of the state code itself and issues its own building, electrical, mechanical and plumbing permits.
This guide covers what requires a permit, the Michigan permit process, fees, trade permits, and inspections — so your Kent County project stays on track.
Kent County — West Michigan’s largest county, home to Grand Rapids, seat Grand Rapids — is made up of cities, villages and townships, and every address in it falls to one of them. The state’s jurisdiction list shows no county programme for Kent County: Grand Rapids, Wyoming, Kentwood, Walker and the other cities, the five villages and all 21 townships each run their own building, electrical, mechanical and plumbing programme. A mailing address does not settle which one governs a parcel, so confirm the unit through the BCC Statewide Jurisdiction List before you file.
Michigan enforces a single statewide construction code set by the Michigan Department of Licensing and Regulatory Affairs (LARA), Bureau of Construction Codes (BCC), under the Stille-DeRossett-Hale Single State Construction Code Act (Public Act 230 of 1972). Michigan’s defining feature is its enforcing-agency model: a city, village, township, or county may assume administration and enforcement of the state code as the local enforcing agency — running plan review, permits, and inspections itself — or the county may do so for it; where neither has, the State BCC is the enforcing agency and issues permits and inspects directly. The BCC keeps a statewide jurisdiction list so you can confirm which agency governs a specific address. Commercial, industrial, and multi-family buildings follow the Michigan Building Code (MBC); one- and two-family dwellings follow the Michigan Residential Code (MRC). As of 2026 the MBC is based on the 2021 IBC (a 2024 edition is in active rulemaking), while the MRC remains on the 2015 IRC pending the state’s residential update — so Michigan runs its commercial and residential cycles on different editions. The Michigan Mechanical Code (2021 IMC) and Michigan Plumbing Code (2021 IPC) took effect in March 2024, and the Michigan Electrical Code adopts the 2023 NEC (effective March 12, 2024). Local enforcing agencies enforce the state code as written: they set their own fees and procedures but cannot change the code.

Under the Michigan Building Code and Michigan Residential Code, a permit is required for most construction activities:
Permit required
- New residential and commercial construction, additions, and conversions
- Structural and load-bearing alterations
- Reroofing, siding, windows, doors, decks, porches, and ramps
- Finishing basements and attics
- Electrical service changes and most wiring work
- HVAC installations, changeouts, and ductwork
- Plumbing alterations, repipes, and water heaters
- Detached garages, sheds over 200 sq ft (120 sq ft under the commercial code), pools, and signs
Ordinary repair / minor work
- Painting, wallpapering, tiling, carpeting, and cabinet installation
- Minor repairs and finish work that replace materials in kind
- Gutters and downspouts (in many jurisdictions)
- One-story detached accessory structures up to 200 sq ft (120 sq ft under the commercial code), and fences up to 7 ft (zoning approval may still be needed)
Thresholds vary by enforcing agency. When unsure, confirm with the building department before starting.
Get the permit issued before starting work. Building without a permit in Kent County can result in penalties, stop-work orders, and (in many jurisdictions) doubled fees or mandatory correction.
Who handles permitting in Kent County?
Kent County itself issues no building permits. Each city, village and township in the county is its own enforcing agency for the building, electrical, mechanical and plumbing codes: it reviews plans, issues permits and inspects work under the MBC (commercial and multi-family) or the MRC (one- and two-family). Zoning approval comes from the same city, village or township and must be confirmed before a permit issues.

Kent County trade permits
Electrical, plumbing, and mechanical work each needs its own permit and an appropriately licensed contractor.
Electrical permits
Required for service installations, panel upgrades, solar PV, EV chargers, and most wiring alterations. Work is inspected against the 2023 Michigan Electrical Code — the 2023 NEC with Michigan Part 8 amendments. Electrical contractors and master/journeyman electricians are licensed by LARA’s Bureau of Construction Codes. On houses and townhouses, electrical work follows the 2015 Michigan Residential Code.
Plumbing & gas permits
Required for new plumbing, repipes, water-heater changeouts, fixtures, backflow, and sewer connections. Work is inspected against the Michigan Plumbing Code (2021 IPC-based, Part 7, effective March 2024). Plumbing permits go to a plumbing contractor licensed by LARA’s Bureau of Construction Codes, with a licensed master plumber in charge. On houses and townhouses, plumbing follows the 2015 Michigan Residential Code.
Mechanical (HVAC) permits
Required for HVAC installations, changeouts, ductwork, venting and gas piping. Work is inspected against the Michigan Mechanical Code (2021 IMC, Part 9A), or the 2015 Michigan Residential Code on houses and townhouses. Mechanical contractors are licensed across HVAC classifications by LARA’s Bureau of Construction Codes.

Get a free quote →Fire protection & specialty
Sprinkler, standpipe, and fire-alarm work falls under the MBC fire-protection provisions and is coordinated with the Bureau of Fire Services / State Fire Marshal where applicable; appropriately licensed contractors are required. Pools, demolition, signs, and elevators follow separate MBC tracks.
Verify contractor licensing before you sign. Michigan licenses residential work at the state level: anyone who contracts to build, alter, repair, or improve a residential structure on a project worth $600 or more (combined labor and materials) must hold a LARA Residential Builder license or a Maintenance & Alteration (M&A) Contractor license (Michigan Occupational Code, Article 24; MCL 339.2403). Michigan has no statewide commercial general-contractor license — commercial GC requirements are set locally, and cities such as Detroit and Grand Rapids require their own registration. Electrical, plumbing, and mechanical work is licensed separately through LARA’s Bureau of Construction Codes; a Residential Builder or M&A license does not authorize electrical, plumbing, or mechanical work — those trades require their own licensed contractors. Confirm the state Residential Builder / M&A license and any local commercial registration before work begins.
How to get a building permit in Kent County
Confirm the enforcing agency & zoning
Identify the city, village or township that governs the address, using the BCC Statewide Jurisdiction List. Confirm local zoning approval and determine whether the MBC or MRC governs.
Prepare your application package
Assemble the building permit application with construction documents — drawings sealed by a Michigan-licensed architect or engineer where required — plus scope, valuation, zoning approval, and your Residential Builder / M&A and trade-license numbers.
Submit to the enforcing agency
File with that city, village or township building department (or its online portal) and pay the plan-review fee at submission.
Plan review & corrections
Plan reviewers check for code compliance and issue comments or an approval. Address any corrections and resubmit; approval is required before a permit issues.
Permit issuance & fees
Once plans are approved, zoning is satisfied, and fees are paid, the permit is issued. Post it on site. A permit generally becomes invalid if work is not started within 180 days or is abandoned for 180 days, so schedule your start promptly.
Inspections & Certificate of Occupancy
Schedule the required inspections (foundation, framing, rough-in electrical/plumbing/mechanical, energy, and final) with the enforcing agency. A Certificate of Occupancy is required before legal occupancy of new or changed-use space.
