City business license guide
Last updated: April 28, 2026
Starting a business in Detroit can mean more than one filing. Some businesses need a City of Detroit business license. Many also need zoning, building, fire, health, state tax, county name, or federal tax steps.
Bottom line
Detroit does not treat every small business the same way. The City says some, not all, business types need a business license. The city requirement is called a business license, and it is handled through the Buildings, Safety Engineering, and Environmental Department, often called BSEED, through Licensing & Permits and the Business License Center.
Before paying for rent or equipment, check three things: whether your business type is licensed by Detroit, whether the address is allowed under zoning, and whether you need a certificate, permit, inspection, or health/fire approval before opening.
Quick start: what to check first
- Use Detroit’s Business Licensing page to see whether your business type is listed.
- Check the address through the Detroit Zoning Portal or ask BSEED about the legal use of the property.
- If you will lease, buy, remodel, change the use, or open to the public, ask if you need a building permit, Certificate of Occupancy, Certificate of Acceptance, or commercial Certificate of Compliance.
- If you will sell food, operate a food truck, serve alcohol, run a lodging business, operate entertainment, sell from a vehicle or cart, offer tattoo/body art, operate a gas station, tow vehicles, or run a similar regulated use, check the city license category before opening.
- If you will use a trade name as a sole proprietor or partnership, check Wayne County assumed name rules. If you will form an LLC or corporation, check Michigan LARA filings.
- Register with Michigan Treasury or UIA if your sales, employees, withholding, or business activity require it.

City of Detroit business license requirement
The City of Detroit calls the local requirement a business license. The city’s public FAQ says some, not all, business types need one. Do not assume you are exempt because you are small, home-based, online, or already registered with Michigan.
Detroit’s BSEED Business Licensing page lists licensed categories and related clearances. Examples include vendors, lodging, entertainment venues, amusement uses, massage or tattoo/body art, concert cafes, gas stations, motor truck permits, vehicles for hire, parking lots, valet parking, cigarette retail, pet shops, secondhand sales, towing yards, scrap tire businesses, adult uses, carnivals, and riding devices.
Check the city list and ask BSEED Licensing & Permits if your exact activity fits a category. Be specific. Say whether you sell from a store, truck, stand, event, home, online site, or appointment-only space.
Important: Paying a fee or submitting an application is not the same as being licensed. Detroit’s business license application guide says Licensing & Permits reviews the application, invoices the account, gives the applicant a checklist of required approvals, and issues the license only after required approvals are secured.
How renewal terms work
Detroit’s current licensing FAQ says most business licenses are bi-annual and that the city sends an email link to renew. Some categories have their own dates. Use the renewal date shown in your license record, renewal email, or Accela/eLAPS account.
Zoning, buildings, fire, health, signs, and related approvals
In Detroit, the city may need to verify that the location is legal for your use, safe for the public, and approved for your planned work.
Zoning and legal use
BSEED’s Zoning Division handles zoning reviews, conditional land uses, and zoning verification. A Zoning Verification Letter can identify the zoning district, overlay zones, legal land use, and permissions for a proposed use at a parcel.
Some uses need Site Plan Review or a Special Land Use hearing. BSEED’s Zoning / Special Land Use page explains those paths.
Building permits and occupancy
If you build, remodel, add equipment, change the use, or move into a space used for something else, check BSEED before work starts. The city’s Building Permits page says permits may lead to final documents such as a Certificate of Acceptance or, for change of use, new construction, or additions, a Certificate of Occupancy.
BSEED’s Construction Inspection Division explains how to request a Certificate of Occupancy after approved work and inspections. Detroit also says a Commercial Certificate of Compliance is required every two years for all commercial buildings and structures.
Fire Marshal approvals
The Detroit Fire Marshal Division handles fire prevention, inspections, code enforcement, plan review, permits, and business license fire clearances. Detroit’s Fire Permit page lists several Fire Marshal permit forms.
Food, mobile food, and health approvals
If you prepare or serve food to the public, start with the Detroit Health Department. Detroit’s Food Safety Licensing page says all food facilities, including permanent, temporary, fixed, or mobile facilities, must obtain a license before beginning operations. It also says there is no separate catering license; a catering business is licensed as a Food Service Restaurant and must meet restaurant requirements.
Food trucks, hot dog carts, ice cream trucks, and similar businesses should check Detroit’s Mobile Food Establishments and Special Transitory Food Units page. Detroit says a business license and plate from the Business Licensing Center is also required. For construction, remodeling, or a new mobile unit, Detroit’s Food Safety Plan Review page says plan review is needed before construction starts.
Signs and exterior advertising
If you install, repair, replace, or change a business sign, check BSEED sign rules before ordering the sign. Detroit has a page for Advertising and Business Sign Permits.
Home-based businesses should also check local zoning and lease or HOA rules. Our home occupation permit guide explains why a home business can still have local rules.
Wayne County requirements that may apply
Wayne County is not the same as the City of Detroit. A business inside Detroit should first check Detroit rules. County filings still matter in some cases.
The most common county issue is a trade name. The Wayne County Clerk says assumed names are handled by mail, and that a certificate of conducting business under an assumed name or certificate of co-partnership must be filed with the Wayne County Clerk’s Office if you are doing business in Wayne County.
The Michigan LARA publication on business names says assumed names of sole proprietorships and co-partnership names are filed with the county clerk in each county where business is conducted. If you form an LLC, corporation, limited partnership, or other state-filed entity, your name and assumed name rules may run through the State of Michigan instead.
What does this mean for me? If you are “Maria Lopez” doing business as “East Side Event Balloons” without an LLC or corporation, ask Wayne County about an assumed name filing. If you form “East Side Event Balloons LLC,” check Michigan LARA and then ask Detroit whether your activity needs a city business license or zoning approval.
Michigan state registrations that may apply
Michigan does not replace Detroit’s local approval process. State filings depend on what you sell, how your business is formed, and whether you have workers.
Entity filings with LARA
The Michigan Department of Licensing and Regulatory Affairs, usually called LARA, handles many business entity filings through the Corporations Division. LARA says the division facilitates formation of corporations, limited partnerships, LLCs, and LLPs, and handles authority for foreign entities to transact business in Michigan. If you form an LLC or corporation, keep up with the state’s annual report or annual statement rules.
For plain differences between legal structure, trade names, sales tax, and local licenses, see business license vs LLC vs DBA vs seller’s permit.
Michigan tax and employer accounts
Michigan Treasury’s New Business Registration page says business tax registration begins through Michigan Treasury Online. If the business has a federal EIN, the EIN is also the Treasury business account number. Michigan UIA says employers can register for most Michigan business taxes, including a UIA account number and sales tax license, using e-Registration, and that employers with employees covered by Michigan UI law must register for an employer account through UIA employer resources.
State professional and industry licenses
Some work needs a state license even when Detroit also has local steps. Examples may include contractors, health occupations, child care, cannabis, liquor, transportation, food manufacturing, or other regulated fields. Food businesses may also need to check Michigan Department of Agriculture and Rural Development rules when MDARD, rather than a local health department, is the licensing agency.
Federal steps that may apply
Many Detroit businesses need a federal Employer Identification Number, or EIN. The IRS says you generally need an EIN if you hire employees, operate a partnership or corporation, pay sales or excise taxes, change your business structure or ownership, or administer certain trusts, retirement plans, and estates. Apply through the IRS EIN page, not through a paid impostor site.
Most small businesses do not need a special federal operating license. But federal permits may apply to activities such as alcohol, aviation, firearms, fish and wildlife, commercial fisheries, mining, nuclear energy, radio and television broadcasting, or transportation. The SBA’s federal licenses and permits list points to the federal agency tied to each activity.
Beneficial ownership reporting rules changed after the original 2024 rollout. FinCEN’s current BOI page says U.S.-created entities and their beneficial owners are exempt, while certain foreign entities registered to do business in the United States may still have duties under FinCEN BOI rules.
Costs you can plan for
Detroit license and permit costs depend on the exact business type, use, location, and approvals. Do not budget from a third-party blog. Check the official city page, Accela/eLAPS invoice, fee schedule, or agency office before paying.
| Cost item | Verified detail | What to do |
|---|---|---|
| Detroit business license fee | Varies by license type. Detroit’s business licensing page lists fees for many categories. | Find your exact category and confirm the current Accela invoice before paying. |
| Zoning Verification Letter | Detroit lists the fee as $93. | Use it when you need written zoning information for a parcel. |
| Site Plan Review | Detroit’s zoning page lists a $160 Site Plan Review fee. | Check whether your use or project requires site plan review. |
| Special Land Use hearing | Detroit’s zoning page lists a $1,160 fee for Special Land Use application steps. | Confirm before applying because fees and process details can change. |
| Wayne County assumed name | Wayne County lists a $16 filing fee on its assumed name page. | Use the county’s mail-in process and notarized form if it applies. |
| Food, fire, building, sign, and inspection fees | These vary by permit, review, inspection, or license. | Ask the specific department for the current fee before work starts. |
Do not treat these as your full startup cost. Rent, build-out, contractor plans, architect or engineer drawings, insurance, equipment, inspections, state tax accounts, and professional help may cost more than the city filing fees.
Real-world examples
Example 1: Online seller from a Detroit apartment
A home-based online seller may not see a simple citywide “all businesses” license. Still, they should check zoning, lease rules, Michigan tax registration if selling taxable goods, and whether any product type is regulated. If customers, inventory, employees, signs, food, or pickup traffic are involved, local rules become more important.
Example 2: Food truck in Detroit
A food truck may need Detroit Health Department mobile food approval, a Detroit business license and plate, fire inspection if there is cooking equipment, propane, or a generator, and Michigan tax registration. See our food truck license guide for the common permit stack.
Example 3: New salon or tattoo studio
A storefront personal service business should check whether Detroit lists the activity under a license category, whether the address has the right legal use, whether build-out needs permits, and whether state professional rules apply. Tattoo/body art is listed by Detroit under consumer services, with health, fire, property maintenance, and Treasury clearances shown on the city page.
What to do if this does not work
If the city page, Accela/eLAPS portal, or permit path does not clearly match your business, do not guess. Use a short written message and ask the agency to identify the correct path. Include your business type, exact address or proposed area, whether you are home-based, mobile, storefront, food-related, or online, and whether you will have employees, signs, customer visits, vehicles, cooking, alcohol, or construction.
If you get different answers, ask for the rule, page, checklist, or permit name that applies. Save the reply. For leases, build-outs, liquor, cannabis, health, fire, zoning, or large investments, talk with a qualified local professional before spending more money.
Common mistakes to avoid
- Assuming an LLC means you do not need a Detroit business license, zoning approval, or tax account.
- Signing a lease before checking whether the proposed use is legal at the address.
- Starting construction before plan review, building permits, or food plan review are approved.
- Opening after paying an invoice but before the actual license, inspection, clearance, or certificate is issued.
- Using a trade name in Wayne County without checking whether a county or state assumed name filing applies.
- Forgetting Detroit Treasury clearance or employer withholding duties when hiring workers or doing business in the city.
- Ordering signs before checking sign permit rules.
- Relying on an old PDF or third-party post instead of the current agency page or your current Accela record.
