Why You Need a Mechanical/HVAC Permit
In Detroit, all mechanical and HVAC installations are regulated under the Michigan Building Code (based on the International Mechanical Code) as adopted by the state and locally administered by the Detroit Buildings, Safety Engineering, and Environmental Department (BSEED). This means your restaurant's heating, ventilation, air conditioning, kitchen exhaust hoods, ductwork, and gas piping must comply with state safety and energy efficiency standards. The requirement is enforced through Detroit's local building ordinances, which mandate that any new installation, replacement, or significant modification of these systems requires a permit and inspection to ensure public safety, proper ventilation, and energy code compliance.
Proceeding without this permit carries immediate and costly consequences. Based on ApronPrep's analysis of enforcement actions in Detroit, the primary penalties include:
- Stop-Work Orders: BSEED inspectors can halt all construction on-site, freezing your project indefinitely until the violation is corrected.
- Daily Fines: Violations can incur compounding daily fines until compliance is achieved. While specific amounts vary by violation severity, they are authorized under local ordinance.
- Certificate of Occupancy Denial: The city will not issue a final Certificate of Occupancy for your new or renovated space, meaning you cannot legally open for business.
- Required Demolition: Non-compliant work may be ordered to be torn out and re-done at your expense, adding significant cost and delay.
- Insurance & Lease Implications: Work performed without a permit may void property insurance claims related to the system and constitute a breach of most commercial lease agreements.
Legal code: State building code (locally administered), local building ordinances, state accessibility code
Recent update: As of 2026, Detroit BSEED has implemented updated fee schedules and may require additional energy compliance documentation for HVAC systems under recent amendments to the state-adopted code.
Who Needs a Mechanical/HVAC Permit?
| Type | Required | Notes |
|---|---|---|
| Restaurant (Full-Service) | Required | Mandatory for all new installations and major modifications of mechanical systems (heating, ventilation, exhaust) under Detroit City Code, Building Construction Article III, § 10-3-1. |
| Bar / Nightclub | Required | Required due to the installation of complex HVAC, kitchen exhaust hoods, and makeup air systems necessary for occupancy, as per the Michigan Mechanical Code adopted by Detroit. |
| Food Truck | Not Required | Mobile units are regulated under vehicle codes and mobile vending permits; a Detroit Mechanical/HVAC Permit is not issued for a vehicle chassis, but any permanent, fixed utility connections at a commissary require it. |
| Coffee Shop / Café | Required | Required if installing or replacing HVAC equipment or kitchen ventilation for food preparation areas, as defined by the Detroit Buildings, Safety Engineering, and Environmental Department (BSEED). |

18 of 22 auto-filledProperty Street Address
textEnter the complete street address where the mechanical work will be performed, exactly as recorded with the Detroit Assessor's office; do not use P.O. Boxes or incomplete addresses like '123 Main'.
COMMON MISTAKE: Submitting a general business mailing address or a contractor's office address instead of the physical job site location, which is an automatic rejection.
Property ZIP Code
textEnter the five-digit ZIP code for the property; verify it matches the official city zoning map for Detroit, as the permit fee structure can vary by district.
COMMON MISTAKE: Incorrect ZIP codes from a broader metro area (e.g., using 48127 for a Detroit address) cause delays in the Department's routing and fee calculation.
Building Type
textSpecify the building's primary use classification as defined by the Detroit Building Code (e.g., 'A-2 Assembly Restaurant', 'B Business', 'M Mercantile'); this determines the applicable mechanical code sections.
COMMON MISTAKE: Using vague descriptions like 'commercial' or 'restaurant' instead of the official code occupancy group letter and description, which triggers a plan review for clarification.
Contractor Business Name
textEnter the licensed contracting company's legal name exactly as it appears on the Michigan Department of Licensing and Regulatory Affairs (LARA) license and the Detroit Buildings, Safety Engineering, and Environmental Department (BSEED) registration.
COMMON MISTAKE: Using a DBA ('Doing Business As') name not formally registered with the state or city, which invalidates the license verification.
Contractor Federal Employer ID Number
textEnter the nine-digit Federal Employer Identification Number (FEIN) issued by the IRS to the contracting business entity, formatted as XX-XXXXXXX, for city tax and verification purposes.
COMMON MISTAKE: Submitting a personal Social Security Number (SSN) or an EIN for a different, inactive, or dissolved business entity, which halts the application.
Michigan State Contractor License Number
textEnter the active Michigan license number for the appropriate mechanical contractor classification (e.g., Mechanical Contractor 'M') as issued by LARA; the license must be in 'active' status.
COMMON MISTAKE: Providing an expired license number or a license for an incorrect trade (e.g., a plumbing license), resulting in immediate application denial per Detroit Code of Ordinances § 9-1-22.
Michigan License Expiration Date
textEnter the expiration date of the state mechanical license in MM/DD/YYYY format; the date must be after the planned permit issuance date.
COMMON MISTAKE: Entering the license issue date or a date format like '12-31-2026' instead of the required MM/DD/YYYY, requiring manual correction and re-submission.
Detroit City Registration Number
textEnter the unique registration number assigned by Detroit BSEED to the contractor, which is separate from the state license and required for all work within city limits.
COMMON MISTAKE: Leaving this field blank or entering the state license number, assuming it fulfills the city requirement; Detroit mandates separate registration.
Detroit Registration Expiration Date
textEnter the expiration date of the Detroit BSEED contractor registration in MM/DD/YYYY format; an expired registration invalidates the entire permit application.
COMMON MISTAKE: Submitting with an expiration date that occurs before the planned project completion, which BSEED flags for non-renewal, delaying approval.
Workers Compensation Insurance Active
checkboxCheck this box to affirm that the contractor maintains active Michigan Workers' Disability Compensation coverage as required by MCL 418.611; you must provide a certificate of insurance (ACORD form) if requested.
COMMON MISTAKE: Checking the box without valid, current coverage or failing to provide proof upon BSEED's request, which leads to a 'stop work' order on any issued permit.

Top 5 Mechanical/HVAC Permit Mistakes
1. Mistake Title
Incorrectly describing the scope of work as 'repair' instead of 'replace' or 'install new.' The Detroit Buildings, Safety Engineering, and Environmental Department (BSEED) reviews 'repair' permits for minor fixes only. If you're swapping out an entire furnace, calling it a 'repair' will cause your application to be rejected for understating the work. This mistake adds 2–3 weeks to your timeline as you must resubmit with the correct permit type. Be specific: 'Replace 3-ton rooftop unit' or 'Install new ductwork for kitchen hood.'
2. Mistake Title
Submitting incomplete contractor or master mechanical license information. The permit application requires the licensed contractor's name, license number, and company address exactly as registered with the State of Michigan. A common rejection reason is entering a business trade name instead of the legal entity name on the license, or providing an expired license number. BSEED will not process the permit without valid, active licensure verification. Always confirm your contractor's current license status on the Michigan Department of Licensing and Regulatory Affairs (LARA) website before applying.
3. Mistake Title
Failing to submit required equipment cut sheets or manufacturer specifications. Detroit's Mechanical Code (based on the Michigan Mechanical Code) requires submittal of technical data showing the equipment's BTU input/output, electrical requirements, and compliance with efficiency standards. Applications submitted with just a model number or without the spec sheets are placed on hold, delaying review by 1–2 weeks. For example, for a new boiler, you must include the manufacturer's installation manual and the data plate showing its BTU rating and ANSI Z21.13 certification.

Timeline: Varies
Stepโ€ฏ1: Gather required documentation including property information, mechanical contractor details, and state/local license numbers
Collect the restaurant's legal address, parcel ID (from Wayne County property records), and detailed equipment specifications for all new or replacement HVAC units. You'll also need your Michigan Business Tax ID, your contractor's state license number, and their Detroit City registration certificate. Skipping the parcel ID is a common cause for application return. This prep typically takes 1-2 hours.
Step 2: Complete the Mechanical Permit Application form with accurate building type (Commercial for restaurant), job type (New or Repair), and contractor information
Use the City of Detroit's specific Mechanical Permit Application form, selecting 'Commercial' as the Building Type and the precise job type (e.g., 'New Installation' or 'Replacement'). All contractor license and registration numbers must match the certificates gathered in Step 1. Incorrectly checking 'Residential' will cause immediate rejection. Completing the form takes about 30-60 minutes.
Step 3: Verify mechanical contractor holds valid Michigan State Contractor License and Detroit City Registration
Before submission, confirm your contractor's Michigan Department of Licensing and Regulatory Affairs (LARA) mechanical license and their separate City of Detroit Buildings, Safety Engineering and Environmental Department (BSEED) registration are both active and in good standing. Work performed by an unregistered contractor violates Detroit City Code § 8-1-3 and can void the permit. This verification takes 1 day.

See All RequirementsProcessing time varies significantly based on project scope and plan review complexity. According to the Detroit Buildings, Safety Engineering, and Environmental Department (BSEED) application guide, minor replacements may be reviewed in 5–10 business days, while major installations requiring detailed plans can take 3–6 weeks. You cannot begin work until the permit is issued and on-site, so plan this timeline before starting a related Building Permit project.
Government filing fees range from $224 to $3,202, as per the Detroit BSEED fee schedule. The final cost is based on the total valuation of the mechanical work, using a formula tied to project size and equipment costs. This permit fee is separate from any costs for the required Certificate of Occupancy or other inspections.
No. Mechanical permits in Detroit are issued for a specific location, scope of work, and contractor. If you relocate equipment or move your business, you must apply for a new permit at the new address, as stated on the BSEED website. The original permit becomes invalid, and working under it at a new site can trigger stop-work orders and fines.
You do not renew a mechanical installation permit. The permit is valid only for the duration of the approved project and its final inspection. However, the installed systems must be maintained to code and are subject to periodic inspections by BSEED, often triggered during annual fire safety checks or if you apply for other permits.
A BSEED inspector will visit the site to verify the installation matches the approved plans and meets the Michigan Mechanical Code and Detroit ordinances. They check equipment sizing, clearances, ductwork, fuel gas lines, electrical connections, and safety devices. Failing the inspection typically requires rework and a re-inspection fee, adding 1–2 weeks to your project timeline.
