In Detroit — Michigan’s largest city and the seat of Wayne County — building permits are issued by Buildings, Safety Engineering and Environmental Department (BSEED), the city’s local enforcing agency under Michigan’s Bureau of Construction Codes. It reviews plans, issues permits, and inspects work for both the Michigan Building Code and Michigan Residential Code.
This guide covers what requires a permit, the Michigan permit process, fees, trade permits, and inspections — so your Detroit project stays on track.
Detroit — Michigan’s largest city and the seat of Wayne County — runs a city building department that acts as the local enforcing agency for the Michigan construction code. As an enforcing agency it reviews plans, issues permits, and inspects work for the MBC and MRC, and typically publishes a fee schedule and an online permit portal; new commercial projects also route through zoning and other reviews before a permit issues. Confirm the current submittal requirements with BSEED 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 on the state’s behalf — 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 may adopt stricter standards through LARA-approved local rules but cannot fall below the state minimum.
What requires a building permit in Detroit?
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 local threshold, fences, 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)
- Small accessory structures below the local size threshold (verify locally)
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 Detroit can result in penalties, stop-work orders, and (in many jurisdictions) doubled fees or mandatory correction.
Who handles permitting in Detroit?
Buildings, Safety Engineering and Environmental Department (BSEED) reviews plans, issues permits, and inspects work in Detroit. As the city’s enforcing agency it employs a building official, plan reviewers, and inspectors who confirm each project meets the MBC (commercial/multi-family) or MRC (one- and two-family). Zoning approval is handled separately and must be confirmed before a permit issues.

Detroit building permit cost
Michigan permit fees are set by each enforcing agency’s adopted fee schedule — typically by valuation or square footage. Where the State BCC is the enforcing agency, Michigan’s statewide permit fee schedule applies. Plan-review fees are generally due at submission.
| Fee component | How it works |
|---|---|
| Plan review fee | By valuation or square footage, set by the enforcing agency’s adopted fee schedule; generally due at submission |
| Building permit fee | Set by the enforcing agency; where the State BCC is the enforcing agency, Michigan’s state permit fee schedule applies |
| Trade permit fees | Separate electrical, plumbing, and mechanical permit fees by device, fixture, or unit |
| Plan-review surcharge | Some agencies add a plan-review or technology surcharge to the base permit fee |
| Certificate of Occupancy | Separate CO fee where applicable |
| Work without a permit | Penalties, stop-work orders, and (in many jurisdictions) doubled or investigation fees |

Detroit 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 Electrical Administrative Board.
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 State Plumbing Board.
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.
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 (the Electrical Administrative Board, State Plumbing Board, and Mechanical Division); 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 Detroit
Confirm permit requirement & zoning
Contact BSEED. Confirm zoning approval, identify the correct permit type, and determine whether the MBC (commercial/multi-family) or MRC (one- and two-family) governs. Verify any flood or environmental requirements before applying.
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 BSEED (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 (MBC/MRC), so schedule your start promptly.
Inspections & Certificate of Occupancy
Schedule the required inspections (foundation, framing, rough-in electrical/plumbing/mechanical, energy, and final) with BSEED. A Certificate of Occupancy is required before legal occupancy of new or changed-use space.
Inspections in Detroit
Schedule inspections through BSEED. Standard checkpoints include foundation, framing, rough-in electrical/plumbing/mechanical, insulation/energy, and final. A Certificate of Occupancy is required before legal occupancy of new or changed-use space.
Address correction notices before requesting a re-inspection; a final inspection and Certificate of Occupancy are required before legal occupancy or use.
