Franklin County, Ohio business license guide
Last updated: October 7, 2026
Starting a business in Franklin County can mean dealing with a city, village, township, Franklin County, the State of Ohio, or several of them at the same time. The hard part is not finding one “Franklin County business license.” It is finding the government that controls your exact address and activity.
This guide explains that map, including Franklin County’s unusual township zoning split and the separate food-licensing territories of Columbus Public Health and Franklin County Public Health.
Bottom line
Franklin County’s official business resources do not identify one general countywide business license that every business must obtain. Instead, the county routes owners to Ohio registrations and licenses, the local municipality or township that controls the address, and county or health agencies for specific functions.
The address question matters more here than in many counties. Franklin County Economic Development & Planning administers zoning for ten townships, while seven other townships administer their own zoning. Incorporated cities and villages have their own local processes. Food licensing follows another map: Columbus Public Health handles Columbus and Worthington, while Franklin County Public Health handles Franklin County outside those two cities.
Do not treat an Ohio LLC filing, trade name, vendor’s license, food license, zoning approval, or Columbus activity-specific license as substitutes for one another. They answer different questions.
Quick start: use this order
- Pin down the exact business address. Do not rely on the city name printed in the mailing address.
- Identify the local government and zoning authority. Use Franklin County’s jurisdiction tools and local-government directory before signing a lease or changing a home use.
- Describe the activity precisely. “Food business,” “contractor,” or “online seller” is too broad. Write down what you sell, where customers go, whether food is prepared, whether vehicles or signs are used, and whether employees will work there.
- Check local zoning and premises approvals. Ask about permitted use, change of use, zoning compliance, building approval, occupancy, fire review, signs, parking, and home occupation rules that apply at the address.
- Check the Ohio layer. Review entity or name filings, tax registration, a vendor’s license if you make taxable retail sales, professional or industry licensing, and employer accounts if you hire.
- Add activity-specific approvals. food, mobile vending, child care, construction trades, transportation, and other regulated activities may have separate agencies.
For the broader state layer, use BLG’s Ohio business license guide. For the basic government-layer distinction, see city license vs. county license vs. state registration.
County, city, township, or state? Start with this decision
“Franklin County” is a geographic description, not a single licensing authority. A Columbus storefront, a home business in Brown Township, a shop in Dublin, and a warehouse in a self-zoning township can follow different local paths even though all are connected to Franklin County.
| Issue | Inside an incorporated municipality | Unincorporated area | Ohio layer |
|---|---|---|---|
| General/basic business license | Check the city or village. Local requirements vary by activity and jurisdiction. | No general countywide license was identified in the county’s official business guidance; check township/county land-use rules and any activity-specific requirement. | Ohio has entity, name, tax, professional, and industry filings rather than one universal state business license. |
| Business or local income tax | Municipal income-tax registration may apply. The administrator can be the municipality, RITA, or another system. | Do not assume “unincorporated” means no local tax. A JEDD/JEDZ or other tax jurisdiction may matter. | Use Ohio tax systems and The Finder for address-based tax jurisdictions. |
| DBA / assumed business name | Ohio uses Secretary of State trade-name and fictitious-name filings. This is not a Franklin County business-license filing. | Ohio Secretary of State. | |
| Zoning | Usually the city or village zoning authority. | Franklin County EDP handles ten townships; seven townships administer their own zoning. | State law provides the legal framework, but the practical land-use approval is local. |
| Building / occupancy | Use the certified building authority for that municipality or area. | County handles specified residential building work; the county says the State of Ohio issues commercial building permits in its unincorporated framework. | Ohio Department of Commerce is important for commercial building permits where the county directs projects to the state. |
| Food / health | Columbus Public Health for Columbus and Worthington; Franklin County Public Health for Franklin County outside those two. | Franklin County Public Health, subject to state food-law roles and the exact operation type. | Ohio Agriculture and Ohio Health also regulate certain food activities. |
| Employer accounts | Local withholding can depend on work location and tax jurisdiction. | Ohio withholding, unemployment, workers’ compensation, and new-hire reporting may apply. | |
Is your address actually inside a city or village?
A “Columbus” mailing address does not prove the parcel is inside Columbus city limits. The same problem can arise with other mailing names. Before you apply for a permit, look up the parcel and identify the government that controls zoning and building approvals.
Franklin County’s Planning & Zoning page provides a Building and Zoning Jurisdiction Lookup and explains the township split. The county’s cities, townships, and villages directory links to local governments. For tax jurisdiction, use the Ohio Department of Taxation’s The Finder, then verify the result with the relevant taxing authority when needed.
Before you sign a lease: ask the zoning authority to confirm that your exact proposed use is allowed at the exact address. A landlord’s statement that a site is “commercial” does not answer whether your restaurant, salon, repair shop, warehouse, child-care use, sign, or outdoor activity is allowed.
What Franklin County actually handles
Franklin County still has important business functions even though it is not a one-stop county licensing office. The strongest county roles for an ordinary small business are jurisdiction guidance, zoning in part of unincorporated territory, certain residential building functions, public-health functions outside the Columbus/Worthington health district, and practical routing to state and local agencies.
The county’s Business Location & Compliance page is unusually useful because it changes the path based on whether the business is home-based, mobile, or in commercial property. The county’s Following the Law page also separates local, state, food-safety, building, zoning, tax, and employer layers.
Unincorporated Franklin County: the zoning split is the key
Franklin County Economic Development & Planning says it administers zoning for Brown, Clinton, Franklin, Hamilton, Madison, Mifflin, Norwich, Pleasant, Sharon, and Truro townships. It also states that Blendon, Jackson, Jefferson, Perry, Plain, Prairie, and Washington townships administer their own zoning and do not fall under county EDP zoning jurisdiction.
For property subject to the Franklin County Zoning Resolution, the county’s zoning page says a Certificate of Zoning Compliance is required before changing the use of buildings or land and for specified construction or land-disturbance activity. The county’s planning FAQ specifically lists home occupations, commercial buildings, changes in use, and signs among common projects that require zoning compliance.
The county currently posts a Franklin County Zoning Resolution effective February 20, 2026. Use the current county page and permit portal rather than an older saved copy of the resolution or an old form.
Building authority is a separate question. Franklin County says its Building Department issues permits for one-, two-, and three-family residential structures and associated development, while the State of Ohio issues commercial building permits in this county framework. The county’s business portal likewise directs commercial building permits in unincorporated Franklin County to the Ohio Department of Commerce Division of Industrial Compliance.
Do not assume “unincorporated Franklin County” automatically means Franklin County zoning. First identify the township. Seven townships run their own zoning systems.
Inside a city or village, use that local government’s rules
If the property is incorporated, county zoning is usually not the starting point. Use the city or village’s own planning, zoning, building, tax, and licensing pages. Franklin County’s local-government directory is the safest routing page when you do not know which site to use.
Columbus is a good example of why “business license” needs precise language. The Columbus Business License Section publishes a list of specific license categories, including mobile food vending and other regulated activities. That page is not a statement that every ordinary business needs one universal Columbus license.
If the business is inside Columbus, BLG also has a verified Columbus, OH Business License Guide. Use it together with current city pages, because a county guide cannot reproduce every Columbus permit path.
Other municipalities can use different zoning portals, tax administrators, and permits. Use The Finder for the address, then follow the named local tax administrator.
Home businesses: zoning comes before the word “license”
A home business can be lawful as a business entity and still have a land-use problem. Customer visits, employees, parking, deliveries, signs, noise, equipment, inventory, outdoor storage, and the exact type of work can change the zoning answer.
If the home is in one of the ten townships under Franklin County EDP zoning, start with the county zoning page and permit portal. Franklin County’s Planning & Zoning FAQ lists home occupations as a common use requiring a Certificate of Zoning Compliance. If the property is in one of the seven self-zoning townships, use that township’s zoning office instead. If the address is in an incorporated city or village, use that municipality’s rules.
Do not use one township’s home-occupation limits as though they apply countywide. Food, child care, personal services, repair work, and other regulated activities can add separate state or health rules.
For the general concept, BLG’s home occupation permit guide explains why a home-use approval is different from an LLC, tax account, or professional license.
Food businesses: Columbus/Worthington and the rest of the county split
This is one of the clearest reasons Franklin County deserves its own guide. Health jurisdiction does not follow a simple “city versus county” rule.
Columbus Public Health (CPH) licenses and inspects retail food businesses in the cities of Columbus and Worthington. Its current Food Protection Program covers restaurants, grocery stores, bars, delis, convenience stores, vending, food carts, and food sold at fairs and festivals, with separate processes for new facilities, mobile operations, and temporary food operations.
Franklin County Public Health (FCPH) states that it inspects food facilities in Franklin County outside Columbus and Worthington. Its Food Safety program covers food service operations, retail food establishments, mobile food operations, vending, and related facilities.
Mobile food adds another layer. Franklin County’s Business Location & Compliance page says the health-license route is based on the business address: CPH for a business address in Columbus or Worthington and FCPH for a Franklin County address outside those cities. But a mobile food vendor that operates in the City of Columbus must also follow the City of Columbus Mobile Food Vending license process. Columbus Fire likewise states that mobile food vendors operating in Columbus generally need a current city MFV license.
State food rules can still apply. The county portal points certain home bakery, processing, wholesale, meat, poultry, dairy, and other food operations to the Ohio Department of Agriculture. A local food license does not necessarily cover every production activity.
If you are planning a food truck, BLG’s verified food truck license and permit guide explains the layers that commonly stack together. For a home food business, the cottage food business guide gives the national framework; Ohio’s current official rules control the final answer.
Ohio entity, name, tax, and employer steps
Entity and business-name filings
Franklin County is not the normal DBA filing office. Ohio uses state-level business and name filings through the Secretary of State. If you form an LLC, corporation, or another registered entity, start with the Ohio Secretary of State Business Services page and the Ohio Business Filings portal.
Ohio’s Secretary of State says “DBA” is a general term. Ohio uses a trade name or fictitious name. A trade name must be distinguishable and can provide exclusive use; a fictitious name does not grant exclusive rights. Neither is zoning approval.
Sales tax and vendor’s license
If you make retail sales that are subject to Ohio sales tax, Ohio law generally requires the appropriate vendor’s license unless an exception applies. Franklin County’s Business Registration & Taxes page directs taxable retail sellers to the Ohio Business Gateway. Use the current state tax path rather than assuming a city or county “business license” handles sales tax.
Municipal income tax and address-based taxes
Franklin County contains many municipal and joint tax jurisdictions. Use The Finder to identify municipal income-tax, school-district, and sales-tax information for an address. The Ohio Department of Taxation itself recommends verifying Finder results with the appropriate municipality or county auditor when needed.
If you hire employees
Hiring creates a separate stack: Ohio employer withholding, unemployment insurance, workers’ compensation, and new-hire reporting. New employers can register for unemployment through The SOURCE. Ohio’s general new-hire reporting deadline is no later than 20 days after the covered hire or engagement.
Professional and industry licensing
Regulated industries can require separate state approval. For other regulated activities, the Ohio Division of other regulated activities Control is the state permit authority, while local zoning and premises rules still matter.
Four Franklin County examples
1. Home-based consultant in Brown Township
First verify that the parcel is in unincorporated Brown Township and under county EDP zoning. Check the home-occupation path, then complete the Ohio name/entity and tax steps that fit the business.
2. Restaurant in Worthington
Worthington handles the local premises path, while Columbus Public Health is the food licensor. Being in Franklin County does not send this restaurant’s food license to FCPH.
3. Mobile food business based outside Columbus but selling in Columbus
The health license follows the applicable health district, while operating in Columbus adds the city’s Mobile Food Vending path.
4. Storefront in a self-zoning township
In Blendon, Jackson, Jefferson, Perry, Plain, Prairie, or Washington Township, start with township zoning rather than county EDP, then identify the building, tax, and activity-specific layers.
Common mistakes
- Searching only for “Franklin County business license.” That phrase hides the real city, township, health, tax, and state layers.
- Using the mailing city as the legal jurisdiction. Confirm the parcel and zoning authority.
- Assuming all unincorporated property uses county zoning. Seven townships administer their own zoning.
- Sending every food business to Franklin County Public Health. Columbus Public Health covers Columbus and Worthington.
- Calling an Ohio trade name a county DBA license. The name filing is with the Ohio Secretary of State and does not grant operating permission.
- Signing a lease before checking allowed use. A change of use, building work, occupancy issue, sign, parking plan, or food build-out can trigger added approvals.
- Assuming a food health license covers mobile vending in Columbus. Columbus has a separate MFV licensing path for operation within the city.
- Ignoring municipal income tax or joint districts. Use an address-based tax lookup instead of guessing from the ZIP code.
What to ask the local agency
When the address or activity is complicated, a short, specific question usually gets a better answer than asking, “Do I need a business license?”
“I am planning a [business type] at [full street address]. The business will be [home-based / storefront / mobile / office / warehouse] and will involve [customers, employees, food, vehicles, equipment, signs, storage, deliveries]. Is this address in your zoning jurisdiction, is this use allowed, and what zoning, change-of-use, building, occupancy, fire, sign, or home-occupation approvals should I complete before opening?”
“My food business is based at [address] and will operate as [restaurant / caterer / mobile unit / temporary event / home bakery / other]. Are you the correct health licensor for this address and operation type? What plan review, license, inspection, and other local approvals apply before I start?”

FAQ
Does Franklin County require one general business license for every business?
Franklin County’s official business guidance does not identify one general countywide business license for every business. The practical path is to identify the city, village, township, or county land-use authority for the address, then add Ohio tax, entity, professional, and activity-specific requirements that apply.
How do I know whether Franklin County or a township handles my zoning?
Franklin County EDP administers zoning for Brown, Clinton, Franklin, Hamilton, Madison, Mifflin, Norwich, Pleasant, Sharon, and Truro townships. Blendon, Jackson, Jefferson, Perry, Plain, Prairie, and Washington townships administer their own zoning. Use the county jurisdiction lookup before applying.
Who licenses restaurants and retail food businesses in Franklin County?
Columbus Public Health licenses and inspects retail food businesses in Columbus and Worthington. Franklin County Public Health handles Franklin County outside Columbus and Worthington. Ohio Agriculture or another state agency can also regulate certain food-production activities, so identify the exact food operation before applying.
Where do I file a DBA in Franklin County, Ohio?
Ohio uses Secretary of State trade-name and fictitious-name filings rather than a Franklin County DBA business-license filing. A trade name or fictitious name records the business name; it does not replace zoning, tax registration, a food license, or another operating permit.
Does a home business need Franklin County zoning approval?
It depends on the address. If the property is in one of the ten townships under Franklin County EDP zoning, the county’s planning FAQ lists home occupations among common uses requiring a Certificate of Zoning Compliance. Self-zoning townships and incorporated municipalities use their own zoning rules.
If my food truck has a health license, can I automatically operate in Columbus?
No. A health license and a Columbus operating license are separate. A mobile food business may receive its health license through Columbus Public Health or Franklin County Public Health based on the applicable health district, while operation in the City of Columbus can also require the City of Columbus Mobile Food Vending license and related city inspections.
