Starting a Small Manufacturing or Fabrication Shop in Michigan: Permits, Reviews, and Who to Call
You are leasing, buying, building out, or expanding a small Michigan manufacturing or fabrication shop. The example below follows one broad metal-fabrication purchase and shows who decides each task, what to ask, what to have ready, and the official sources behind it. Products, processes, tanks, land work, materials, and employee hazards can change the list.
You plan to make or fabricate products in the community where the site sits. Local rules can treat the process, noise, truck traffic, outdoor storage, hours, signs, parking, and fire use differently.
Ask
“Is this exact manufacturing or fabrication use allowed at this address? What zoning, site-plan, loading, outdoor-storage, noise, sign, fire, or occupancy approvals come first?”
Have ready
The address and parcel number, short process description, machine list, materials, hours, employee count, truck activity, outdoor uses, and a simple site layout.
Who decides
The city, village, or township that controls land use at the site
This check cannot see the zoning district, interpret a local ordinance, identify every enforcing office, or approve the use.
Trace every process liquid and get the discharge answer in writing
Official check
The process-water or drain destination is not confirmed. A sewer connection or landlord statement is not written approval for an industrial discharge.
Ask
“Where does every floor drain, trench, sink, sump, wash line, scrubber, cooling stream, and outdoor catch basin go? What written sewer, groundwater, surface-water, septic, or hauling approval is required?”
Have ready
Plumbing drawings, drain photos, dye-test or plumber records, process flow, flow estimate, pollutants and concentrations, pH, metals, oils, solvents, treatment, sewer letters, holding-tank and hauler records, and nearby waters or wells.
Who decides
The local sewer authority and plumbing official, with Michigan EGLE for groundwater, surface-water, or other regulated discharges
This check cannot approve a discharge, trace a drain, decide whether pretreatment or a permit applies, or treat a floor drain as permission to use it.
Get the air answer before choosing or moving equipment
Official check
Your answers include a process, exhaust route, collector, booth, oven, furnace, boiler, or engine that may make dust, fumes, mist, smoke, odor, or vapors. Michigan starts with a Permit to Install or a valid, documented exemption before covered equipment is installed or changed.
Ask
“For each emission unit, do we need an air Permit to Install, or does a specific exemption fit after its limits, records, and Rule 278 exclusions are checked?”
Have ready
Equipment make and model, maximum production and hours, every material and SDS, coating or solvent use, fuel and heat input, exhaust destination, stack and collector design, control equipment, and existing air records.
Who decides
Michigan EGLE Air Quality Division and its free Clean Air Assistance Program
This check does not calculate emissions, select an exemption, approve equipment, or show that existing or small equipment is exempt.
The seller's records may describe a different owner, process, production rate, material, exhaust system, or waste stream. Do not assume that each authorization follows the sale.
Ask
“For every permit, exemption record, site ID, sewer approval, stormwater record, tank registration, plan, and reporting account, what must the buyer apply for, update, or confirm before operating?”
Have ready
The asset and equipment list, closing date, seller and buyer names, permits, exemption records, environmental site ID, sewer letters, stormwater coverage, tank records, Tier II filings, inspections, and planned process changes.
Who decides
Each issuing state, federal, sewer, and local program, with transaction counsel
This check cannot decide transferability, update an authorization, or determine whether the buyer's planned operation matches the seller's records.
Make one process map and run the EGLE permit screen
Official check
Manufacturing questions cross air, waste, wastewater, stormwater, storage, and property programs. EGLE offers a permit checklist and free coordination help for new or changed facilities.
Ask
“Using this process and equipment list, which EGLE programs should review the site before we sign, install equipment, change a process, or begin operating?”
Have ready
Process flow, maximum production, equipment list, raw materials and safety data sheets, air outlets, drains, wastes, outdoor activity, storage amounts, site plan, and existing environmental records.
Who decides
Michigan EGLE Environmental Assistance Center and permit coordinator
This is a routing step. It does not decide that a permit, exemption, registration, plan, or report applies.
Michigan warns that a buyer can face successor-liability issues when a business seller has unpaid taxes. The seller can request tax clearance, but the transaction facts still need professional review.
Ask
“Will the seller request current Michigan tax clearance, and what escrow or closing steps should my lawyer or tax adviser use for this purchase?”
Have ready
The purchase agreement, asset and inventory list, seller's legal and tax names, Treasury account details available from the seller, clearance request, closing date, and professional contacts.
Who decides
Michigan Department of Treasury and your qualified legal or tax adviser
This check cannot determine successor liability, interpret the purchase agreement, protect escrow funds, or replace transaction-specific advice.
Check UIA successorship before the business transfer
Official check
Buying a business or most of its assets can affect unemployment-tax liability and the contribution rate. This question belongs in the deal file even if the buyer has not decided its future hiring plan.
Ask
“Which UIA acquisition notice, seller information, clearance, experience-account, contribution-rate, and possible liability steps apply before this transfer, and what deadlines run from the offer or transfer date?”
Have ready
Purchase agreement, asset list and percentage acquired, seller and buyer legal names and UIA account details, offer date, transfer date, seller-provided UIA information, clearance request, payroll history available from the seller, and adviser contacts.
Who decides
Michigan Unemployment Insurance Agency and your qualified legal or tax adviser
This check cannot determine UIA successorship, the buyer's contribution rate, transferred liability, or how the purchase agreement should allocate risk.
Screen the site for industrial stormwater coverage
Official check
You selected outdoor exposure or uncertainty. Industrial materials, loading, scrap, waste, fueling, maintenance, or equipment exposed to rain or snow can raise stormwater permit, plan, operator, inspection, and record duties.
Ask
“Based on the primary industrial activity, every outdoor exposure, and the drainage path, does this site need permit coverage, a No Exposure Certification, or another documented result?”
Have ready
Primary activity and SIC or NAICS help, drainage and outfall map, storm drains and ditches, outdoor inventory and photos, loading and fueling practices, lease responsibilities, and any old coverage, certification, or pollution-prevention plan.
Who decides
Michigan EGLE Industrial Stormwater Program
This check cannot determine coverage. Keeping work indoors does not by itself prove that no stormwater filing or ongoing condition applies.
A building can come with old equipment, unapproved changes, open violations, permit limits, drain questions, or missing environmental records that are hard to spot during a tour.
Ask
“Please provide occupancy and construction records, equipment lists, air permits or exemption records, waste determinations, sewer approvals, stormwater records, chemical inventories, tank files, spill or cleanup records, inspections, and violation notices.”
Have ready
The lease or purchase draft, seller disclosures, asset list, site and floor plans, utility records, permit numbers, agency contacts, and records for equipment that will stay.
Who decides
The owner or seller, then each office that issued or keeps the record
This is a document request. A complete-looking file does not prove the site or equipment is approved, transferable, or free of contamination.
Your work may make dust, sludge, media, spent liquids, oil, coolant, filters, rags, aerosols, batteries, lamps, or off-spec product. The generator must characterize each stream and follow the rules for its waste type and monthly amount.
Ask
“How should each waste be characterized, counted in its busiest month, stored, labeled, inspected, shipped, recycled, and documented? Does the site need an environmental ID?”
Have ready
Process description, SDSs, sample results, waste profiles, monthly weights and volumes, acute or severely toxic waste information, container and storage plan, hauler and destination records, manifests, and site ID.
Who decides
Michigan EGLE Materials Management Division
This check cannot classify a waste or generator category. Very small quantities, recycled material, used oil, universal waste, and nonhazardous liquids can still have rules.
Check the property's environmental history before committing
Official check
Older industrial work, plating, chemicals, tanks, dry cleaning, spills, or unknown drains can leave contamination. Michigan liability protections and due-care duties can matter to a new owner or operator, including some tenants.
Ask
“What environmental review should happen before I become the owner or operator or disturb this soil? Do I need a Phase I assessment, testing, a Baseline Environmental Assessment, a due-care plan, or a soil-management plan?”
Have ready
Historical uses, Phase I or Phase II reports, EGLE files, tank and spill records, permits, violations, cleanup records, site plans, seller disclosures, and the planned closing or occupancy date.
Who decides
A qualified environmental professional, transaction counsel, and Michigan EGLE
This check cannot tell whether contamination exists. A Phase I or Baseline Environmental Assessment does not certify that property is clean or remove every duty.
You selected metal powder, dust, resin, or another inventory that can raise fire, combustible-dust, SDS, storage, and community-reporting questions. The answer turns on the exact material and particle form, maximum amount onsite, container, handling, and layout.
Ask
“For this inventory, process, and layout, what combustible-dust or fire review, emergency-planning notice, safety-data-sheet submission, Tier II report, or other material record is required?”
Have ready
Complete material and chemical list and SDSs, powder or dust form and handling, maximum daily amounts, mixture percentages, container and tank sizes, indoor and outdoor locations, cabinets and containment, ignition and collection equipment, process use, and site map.
Who decides
The local fire-code authority, MIOSHA when employees are exposed, and Michigan SARA Title III Program
This check does not classify a material, calculate a reporting threshold, approve storage, or decide that Tier II reporting applies.
Screen bulk storage, containment, and spill planning
Official check
Fuel, oil, polluting materials, bulk storage, or outdoor fueling can raise overlapping Michigan spill-prevention, federal oil-planning, fire, containment, and release-reporting questions.
Ask
“Using maximum onsite capacity and the largest container—not yearly purchases—which containment, PIPP, SPCC, fire, inspection, and release-reporting duties should we check?”
Have ready
Every product and SDS, maximum onsite capacity, largest container, tanks and cylinders, indoor or outdoor location, drains and outfalls, containment, site slope, delivery plan, and existing response plans.
Who decides
Michigan EGLE, the local fire-code authority, and U.S. EPA where federal oil rules may apply
This check does not calculate thresholds, decide whether a plan applies, design containment, or give one universal spill-reporting amount.
02Before ordering equipment, building, or changing the site
Line up occupancy, building, trade, and fire review
Official check
Your project includes equipment or site work that can require plans, permits, licensed contractors, inspections, or an updated occupancy approval.
Ask
“What is the approved use now? Which building, electrical, mechanical, plumbing, boiler, fire, and occupancy reviews apply before this exact work and equipment can be used?”
Have ready
Certificate of occupancy, approved plans, machine and collector cut sheets, equipment weights and anchoring, electrical loads, exhaust, gas and process piping, plumbing, storage heights and amounts, fire systems, and contractor details.
Who decides
The state, county, or local enforcing agency for each code discipline
Different trades may have different enforcing offices. This check cannot classify occupancy, design the work, approve storage, or confirm that a floor can support equipment.
Check the federal paint-stripping and spray-coating rule
Official check
You selected spraying, coating, or solvent work and said certain coating metals or methylene chloride may be present or are not yet ruled out. Federal Subpart HHHHHH can apply to methylene-chloride paint stripping, spray coating of complete motor vehicles or mobile equipment, and some spray coating of metal or plastic parts.
Ask
“Are we coating complete motor vehicles or mobile equipment, or ordinary parts? Do that category, the coating ingredients, spray method, and paint-stripper chemicals bring the operation into Subpart HHHHHH, and what petition, notice, training, booth, filter, spray-gun, and record duties would follow?”
Have ready
Coating and stripper SDSs and technical sheets, cadmium, chromium, lead, manganese, and nickel content, any methylene chloride or dichloromethane use, parts coated, application method, annual stripper use, booth and filter details, spray guns, painter training, and older notifications.
Who decides
U.S. EPA, with Michigan EGLE Air Quality Division assistance
Spraying, cleaning, or using a booth does not by itself prove this rule applies. This check cannot classify the operation, read product chemistry for you, or complete a notification.
Check the boiler, oven, furnace, kiln, or engine before ordering
Official check
Boilers and stationary engines can raise state air, building, mechanical, fire, boiler, and separate federal air questions. The answer turns on fuel, size, dates, use, hours, and exhaust.
Ask
“What state and federal air review, construction permit, boiler review, licensed installation, inspection, and startup record apply to this exact unit?”
Have ready
Nameplate, make and model, fuel, heat input or horsepower, manufacture and construction dates, emergency or production use, expected hours, exhaust, piping, and equipment location.
Who decides
Michigan EGLE Air Quality Division and the applicable construction-code or boiler office
This check cannot classify the equipment or decide which state or federal rule applies. A Michigan air-permit exemption does not settle separate federal engine or boiler duties.
Set up employer accounts and the incident-reporting path
Official check
Hiring brings unemployment, tax, workers' compensation, workplace-safety, poster, record, and incident-reporting jobs. Serious-event reporting has its own official route and should not be confused with environmental spill reporting.
Ask
“Which employer accounts, insurance, posters, injury and illness records, emergency contacts, and fatality or serious-injury reporting steps must be ready before the first production shift?”
Have ready
Entity and tax IDs, hire dates, payroll plan, job list, expected headcount, workers' compensation information, safety contacts, recordkeeping decision, emergency plan, and incident-reporting instructions.
Who decides
MIOSHA Consultation Education and Training, UIA, Treasury, and the Workers' Disability Compensation Agency
This is a starting handoff. It does not decide recordkeeping coverage, classify workers, run payroll, determine insurance coverage, or replace emergency instructions.
Put the business name and tax accounts in one startup file
Official check
Entity filing, tax registration, and site approval are separate jobs. Keeping the same legal name and address across applications prevents avoidable delays.
Ask
“Which entity or assumed-name filings, annual filings, and Michigan tax accounts fit this business and location?”
Have ready
Legal and assumed names, entity records, owners, federal tax ID, addresses, products, sales channels, expected start date, and hiring plan.
Who decides
Michigan LARA Corporations Division and Michigan Department of Treasury
This check does not recommend an entity type, classify sales, prepare tax returns, or provide legal or tax advice.
Michigan Business RoadmapMichigan Department of Licensing and Regulatory Affairs · Reviewed July 11, 2026
Check the federal metal-fabrication category and notification
Official check
You selected a possible metal-fabrication source category, and cadmium, chromium, lead, manganese, or nickel may be present or is not yet known. Federal Subpart XXXXXX covers nine named source categories and has separate notification and target-metal process questions.
Ask
“Is our primary business in one of Subpart XXXXXX's nine source categories? What initial notification is required, and do the exact processes and metal content add work practices, visible-emission checks, notices, or reports?”
Have ready
Primary products and NAICS or SIC help, metal and filler-wire mill certificates, SDSs, coatings, dust analysis, process list, fume or dust controls, and any older federal notifications.
Who decides
U.S. EPA, with Michigan EGLE Air Quality Division assistance
A metal-business label, welding, machining, or a no-target-metal record does not settle the source category or every notification duty. This check cannot classify the facility or determine metal content.
Check machine guarding and stored-energy work by task
Official check
Employees may use, clean, unjam, adjust, maintain, or service powered equipment. Normal production, setup, troubleshooting, and service can need different guarding and energy-control steps.
Ask
“For each machine and employee task, which guarding, point-of-operation, electrical, startup, lockout or tagout, written-procedure, inspection, and training rules apply?”
Have ready
Machine list and manuals, task and service steps, points of operation, guards and interlocks, electrical and other energy sources, shutdown and restart steps, contractors, written procedures, inspections, and training records.
Who decides
MIOSHA General Industry Safety and Health Division and free consultation staff
This route cannot inspect a machine, approve a guard, write an energy-control procedure, decide an exception, or train an employee.
Build the employee chemical-information starting file
Official check
Employees may handle chemicals, coatings, solvents, oils, or gases. Product labels, current SDSs, the workplace chemical list, employee information, and task-specific training need to match what is actually used.
Ask
“Which hazard-communication, label, SDS, written-program, training, storage, eyewash or shower, and task-specific chemical rules apply before employees use these products?”
Have ready
Complete workplace chemical list, current SDSs, labels and secondary containers, tasks and quantities, storage plan, piping, spill and emergency steps, ventilation, eyewash or shower locations, PPE review, and training records.
Who decides
MIOSHA General Industry Safety and Health Division and free consultation staff
This route cannot classify a workplace exposure, write the program, choose emergency equipment or PPE, approve storage, or train employees.
Get the exposure and respirator questions answered before the shift
Official check
Dust, fumes, welding, spraying, loud noise, and respirator use can raise exposure-assessment, engineering-control, hearing, medical-evaluation, fit-testing, PPE, and training questions.
Ask
“Which air and noise evaluations are needed, which controls come first, and what hearing, respiratory, PPE, medical, fit-test, maintenance, and training steps apply to each job?”
Have ready
Jobs and time by task, materials and SDSs, process and ventilation details, existing air and noise data, proposed respirators and PPE, employee count, maintenance tasks, medical and fit-test plans, and training records.
Who decides
MIOSHA General Industry Safety and Health Division and free consultation staff
This route cannot measure exposure, decide that a respirator is required, select controls or PPE, perform medical evaluation or fit testing, or approve a program.
Plan forklift selection, traffic, and operator training
Official check
Powered industrial trucks bring equipment, operator, inspection, charging or fueling, pedestrian, dock, trailer, aisle, and load-handling questions.
Ask
“Which truck type, workplace evaluation, operator training and evaluation, inspection, charging or fueling, traffic, dock, trailer, and pedestrian safeguards apply here?”
Have ready
Truck types and manuals, loads and attachments, operators, floor and aisle plan, ramps and docks, trailer work, pedestrian routes, charging or fueling area, inspection plan, incidents, and training records.
Who decides
MIOSHA General Industry Safety and Health Division and free consultation staff
This route cannot choose a truck, evaluate an operator, inspect the workplace, design traffic controls, or provide required training.
04After opening, finishing work, or putting the change into use
Give every approval, record, and renewal an owner
Practical step
A permit exemption can still require records, and permits, plans, inspections, waste determinations, training, and reports can run on different schedules.
Ask
“For each approval or exemption, what must we inspect, record, report, renew, update, and keep onsite—and who will own that task?”
Some questions have no safe generic answer without the exact address, records, people, or equipment. The interactive check keeps each one visible instead of turning it into a silent gap:
The exact parcel, zoning district, and enforcing offices are not confirmed.
The process-water and production-drain path is not confirmed in writing.
Waste determinations and busiest-month generator records have not been completed.
The metal, wire, coating, and dust records have not ruled out cadmium, chromium, lead, manganese, or nickel.
