In Wayne County — Michigan’s most populous county, home to Detroit — building permits come from the city, village or township where the work is — Wayne County itself runs no building-code program, and every one of its 43 cities, villages and townships, from Detroit and Livonia to Canton and Van Buren townships, enforces the building, electrical, mechanical and plumbing codes itself. There is no unincorporated land, and no Wayne community relies on the State Bureau of Construction Codes.
This guide covers what requires a permit, the Michigan permit process, fees, trade permits, and inspections — so your Wayne County project stays on track.
Wayne County — Michigan’s most populous county, home to Detroit, seat Detroit — contains 33 cities, one village (Grosse Pointe Shores) and nine townships, with no unincorporated land. The BCC’s statewide jurisdiction list shows no county program in Wayne: each of the 43 communities runs its own building, electrical, mechanical and plumbing program. Confirm the community that holds the parcel — mailing addresses and school districts often cross city lines — 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 — and where no local agency has assumed that role, 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 above the state size limit, 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)
- Fences up to 7 ft (zoning may still need a permit), and one-story sheds up to 200 sq ft next to a house (120 sq ft under the commercial code)
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 Wayne County can result in penalties, stop-work orders, and (in many jurisdictions) doubled fees or mandatory correction.
Who handles permitting in Wayne County?
Building permits in Wayne County are handled by the building department of the city, village or township that holds the parcel. Wayne County government has no building-code program, so it issues no building or trade permits, and no Wayne community uses the State BCC. Each enforcing agency reviews plans, issues permits, and inspects work for the MBC (commercial/multi-family) or MRC (one- and two-family). Township zoning approval is handled separately and must be confirmed before a permit issues.

Wayne 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.
Plumbing & gas permits
Required for new plumbing, repipes, water-heater changeouts, fixtures, backflow, and sewer/gas connections. Work is inspected against the Michigan Plumbing Code (2021 IPC-based, Part 7, effective March 2024). Plumbing contractors and master/journeyman plumbers are licensed by LARA’s Bureau of Construction Codes.
Mechanical (HVAC) permits
Required for HVAC installations, changeouts, ductwork, and venting. Work is inspected against the Michigan Mechanical Code (2021 IMC, Part 9A). Mechanical contractors are licensed across HVAC classifications by LARA’s Bureau of Construction Codes.
On detached one- and two-family houses and townhouses, electrical, plumbing and mechanical work follows the 2015 Michigan Residential Code rather than the electrical, plumbing and mechanical codes above.

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 by 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 Wayne County
Confirm the enforcing agency & zoning
Identify which city, village or township holds the parcel — its building department is the enforcing agency, as the BCC jurisdiction list confirms. Confirm township 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 community’s 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.
