Detroit, MI Business License Guide (2026)

City of Detroit business license requirement

Detroit uses an activity-based business license system, not one general license for every business. The current Business Licensing page groups covered activities and shows clearances, documents, fees, and expiration dates. Examples include certain entertainment uses, massage and tattoo/body art, gas stations, vehicle-related businesses, parking and valet operations, cigarette retail, pet shops, secondhand sales, towing, scrap-related businesses, and vendor categories.

Do not choose a license because its name sounds close. Tell BSEED exactly what you do and whether you operate from a storefront, home, vehicle, stand, event, warehouse, or online business.

License term and renewal

Detroit’s 2025 licensing ordinance changed the general City business-license term from one year to two years, with exceptions including rental halls and sexually oriented businesses that remain on one-year terms. Use the expiration date for your exact category and Accela record; some older City handouts still say annual renewal.

Submitting an application or paying an invoice is not the same as receiving the license. Required inspections and clearances must still be completed.

Zoning, buildings, fire, health, signs, and related approvals

The property is part of the licensing map. A legal business activity can still fail at a particular address if the use, occupancy, construction, or site does not meet Detroit rules.

Zoning and legal use

Start with the Detroit Zoning Portal. For an official written answer, a Zoning Verification Letter can identify the zoning district and legal use. Some projects need Site Plan Review or a Special Land Use hearing; use BSEED’s current Zoning / Special Land Use page. The City also points new businesses to Detroit permit-scoping tool to scope likely permits.

Building permits and occupancy

If you build, remodel, add equipment, or change a use, check BSEED before work starts. Detroit routes commercial permit applications through Building Permits and Accela, with ProjectDox used when plans are required. A Certificate of Occupancy can apply to new construction, major renovations, or a new/change of use. A separate Commercial Certificate of Compliance is required every two years for commercial buildings and structures.

Fire Marshal approvals

The Detroit Fire Marshal handles fire prevention, inspections, plan review, permits, and business-license fire inspections. Its current page says every business type is required to obtain an annual fire permit. Confirm the correct fire record for your premises, especially for cooking, assembly, propane, generators, or hazardous materials.

Food, mobile food, and temporary food

For food, start with Food Safety Licensing. Detroit says permanent, temporary, fixed, and mobile food facilities generally need the applicable food service license, subject to Michigan Food Law exemptions. Food service licenses expire April 30 each year, and new or remodeled establishments may need Food Safety Plan Review before construction.

For trucks and carts, use the Mobile Food / STFU page. Mobile establishments and STFUs have different operating rules; enclosed units using cooking, propane, or a generator need fire inspection. Packaged ice-cream trucks are a special case: Detroit says they may be exempt from food-service licensure but still need Health Department approval plus a Business Licensing Center license and plate.

For a short event, use the temporary food event page. A temporary food establishment may operate at a fixed location for no more than 14 consecutive days; Detroit says to apply at least 10 days before the event to avoid added late fees.

Home-based businesses

Detroit Chapter 50 says a home occupation that meets the City standards is allowed in a dwelling without a separate permit or registration unless the code specifically says otherwise. The code limits a home occupation to 25% of the dwelling or 500 square feet, with a different loft rule. Nonresident employees are barred in R1 and R2 districts and limited to two in other districts. The operator must live there, and traffic, nuisance, and prohibited-use rules also apply. Read Chapter 50, Sections 50-12-481 through 50-12-494.

That zoning allowance does not erase a separate business-license, food, professional-license, tax, lease, or HOA rule. See our home occupation permit guide for the general distinction.

Signs

Detroit says signs attached to a building or ground generally need a permit, including temporary signs, and sign licenses renew annually. Check Advertising and Business Sign Permits before ordering a sign.

Wayne County requirements that may apply

Wayne County is not a second general business-license layer for every Detroit business. A business inside Detroit should first check Detroit rules. The main county filing many small businesses encounter is an assumed name.

The Wayne County Clerk says assumed-name and co-partnership certificates are currently handled by mail until further notice. The form must be notarized, and the current filing fee shown by the County is $16. Sole proprietorship and co-partnership name filings are different from assumed names used by LLCs, corporations, and other state-filed entities.

Michigan state registrations that may apply

Michigan filings do not replace Detroit approvals. The state path depends on your structure, sales, workers, and regulated activity.

Entity filings

Michigan LARA’s Corporations Division handles LLCs, corporations, limited partnerships, LLPs, and related records. The current system is the MiBusiness Registry Portal. LARA says annual reports and annual statements are now filed online there. Do not use retired legacy corporation portals. See also business license vs LLC vs DBA vs seller’s permit.

Michigan tax registration

Michigan Treasury’s New Business Registration page directs businesses to Michigan Treasury Online (MTO). Whether you need sales tax, withholding, or another account depends on your activity.

If you hire

Michigan UIA moved employer unemployment-tax functions from MiWAM to MiUI on February 23, 2026. Employers now use MiUI for unemployment-tax registration and quarterly wage/tax work. Some benefits functions remain in MiWAM until November 9, 2026.

Michigan Treasury administers Detroit employer withholding. Its Detroit Employer Withholding page says a business already registered for Michigan taxes does not separately register just for Detroit withholding; returns use the federal EIN.

Professional and industry licenses

Michigan MiPLUS covers many professional licenses, including cosmetology. Tattoo/body art follows a different path: Detroit says qualifying body-art facilities need a Michigan body-art facility license and a City of Detroit business license, both with Health Department approval. Use the City’s Body Art Facility Licensure page. For alcohol, use the Michigan Liquor Control Commission’s license guide.

Federal steps that may apply

Many Detroit businesses need a federal Employer Identification Number, or EIN. Apply directly through the IRS EIN page. An EIN is a federal tax identifier; it is not permission to operate in Detroit.

Most ordinary small businesses do not need a special federal operating license. Federal permits may apply to activities such as alcohol, aviation, firearms, fish and wildlife, commercial fisheries, mining, nuclear energy, broadcasting, or transportation. The SBA’s federal licenses and permits list routes businesses to the relevant federal agency.

FinCEN finalized the current Beneficial Ownership Information rule on August 11, 2026. Under the current rule, U.S.-created companies are exempt from BOI reporting; certain foreign companies registered to do business in the United States may still have reporting duties. This final rule formalized an exemption framework that was already in practical effect before this review period. Use FinCEN’s current BOI page rather than older 2024 guidance.

Costs you can plan for

Fees depend on the exact license, permit, review, property, and activity. Use the current application record or official fee page before paying.

Real-world examples

What to do if the path is not clear

If a City page or Accela record does not clearly match your business, send BSEED your exact activity, address, operating model, customer visits, employees, vehicles, signs, food, alcohol, equipment, and construction plans. Ask for the exact license or permit category and required clearances.

If City pages conflict, favor the current ordinance, current application page, and current agency instructions. Some older Detroit pages and PDFs still contain annual-license or old food-license wording changed by the 2025 ordinances.
