Business licenses and permits in Hamilton County, Ohio
Hamilton County, Ohio, seat Cincinnati, is a statutory (non-charter) county, and the Legislative Service Commission's Overview of Local Government in Ohio (Members Brief, 2 September 2026) explains what follows from that: 'Counties and townships are creatures of statute - they have only the authority expressly stated in the Revised Code or impliedly derived therefrom,' while 'municipal corporations and charter counties have constitutional home rule authority', and 'the two charter counties (Cuyahoga and Summit)' are the only Ohio counties outside the default structure. Ohio Constitution Article X, Section 3 supplies that limit, and ORC Chapter 307, which states a board of county commissioners' powers and duties, carries only three regulatory sections — 307.37 on adopting a county building code, 307.38 on the county building inspector and 307.39 on publishing building regulations. Every county record here therefore traces to a named Revised Code grant: ORC 5739.17 (vendor's license), ORC 5743.15 (cigarette), ORC Chapter 3717 (food), ORC Chapter 3730 (body art), ORC 3709.21 (health district regulations), ORC Chapter 3718 (sewage systems), ORC 307.37 with Chapter 3781 (building), ORC Chapter 303 (county rural zoning), ORC Chapter 6117 (county sewer district), ORC 4737.07 (junk yards) and ORC 311.37 (the sheriff's transient vendor filing). The county's own Forms, Permits and Licenses page lists what it issues under Licenses — Food Service License, Food Service License Mobile, Food Service License Temporary, Pools and Spas, Tattoo and Piercing Facilities, Vendor's License — and under Permits — Buildings + Inspections, Engineer's Office, Soil & Water Conservation District, Southwest Ohio Air Quality Agency, Stormwater + Infrastructure, Earth Movement Permit and Weights and Measures. Four bodies split the county's map. Hamilton County Public Health licenses food, pools, body art, plumbing and sewage systems in the General Health District, which its own body art page defines as 'within Hamilton County but... NOT within the cities of Cincinnati, Norwood, or Springdale'; its served-communities list names 45 jurisdictions including Sharonville, and the Ohio Department of Health's directory lists only the Cincinnati, Norwood and Springdale city health departments alongside it. Buildings + Inspections states that it 'is responsible for issuing building permits in the unincorporated townships of Hamilton County and in six contract jurisdictions' — Amberley Village, Elmwood Place, Indian Hill, North Bend, Terrace Park and Wyoming, with Elmwood Place, Terrace Park and Wyoming for commercial permits only. Zoning is split three ways on the county's own account — 'zoning adopted for cities or villages, zoning adopted for townships under township trustee jurisdiction, and zoning adopted for townships under county commissioner jurisdiction' — and county Development Services administers only the third, covering 'all of Columbia and Harrison Townships and the majority of Green and Miami Townships' plus Symmes Township and the Village of North Bend by contract. The Metropolitan Sewer District of Greater Cincinnati is a county sewer district under ORC Chapter 6117 that the City of Cincinnati operates. The county lists 37 incorporated cities and villages — Addyston, Amberley Village, Arlington Heights, Blue Ash, Cheviot, Cincinnati, Cleves, Deer Park, Elmwood Place, Evendale, Fairfax, Forest Park, Glendale, Golf Manor, Greenhills, Harrison, Indian Hill, Lincoln Heights, Lockland, Loveland, Madeira, Mariemont, Milford, Montgomery, Mt. Healthy, Newtown, North Bend, North College Hill, Norwood, Reading, Sharonville, Silverton, Springdale, St. Bernard, Terrace Park, Woodlawn and Wyoming — and 12 townships: Anderson, Colerain, Columbia, Crosby, Delhi, Green, Harrison, Miami, Springfield, Sycamore, Symmes and Whitewater. Each city and village runs its own licensing, building and zoning regime on top of, or in place of, the county records below, which is why the first question at any Hamilton County address is which of these authorities it falls under.

- RestaurantsFull-service restaurants carry the densest permit load of any small business: food, fire, occupancy, waste, and usually alcohol.See the full permit list
- Coffee shopsCafés are permitted as food service establishments even where no cooking happens, and the plan review step catches most operators by surprise.See the full permit list
- Retail storesRetail is the lightest common permit load, but the sales tax permit and the certificate of occupancy are non-negotiable in every jurisdiction.See the full permit list
- Salons and barbersPersonal care is licensed at state board level as well as locally, so the shop license and the practitioner licenses are separate obligations.See the full permit list
- Food trucksMobile food is the one category with no certificate of occupancy — but it gains a commissary agreement, and the unit itself is inspected rather than the premises.See the full permit list
- Fitness studiosPrepaid memberships trigger state registration and often a surety bond, which catches operators who budgeted only for the fit-out.See the full permit list
- Childcare centresThe heaviest permit load of any small business: state agency licensing, per-person background checks, and a stricter fire standard than ordinary commercial use.See the full permit list
- Contractors and tradesLicensed at state board level rather than locally, and the only common category with no premises permits at all — the bond is usually the long pole.See the full permit list
- Auto repair shopsOrdinary commercial permitting plus an environmental layer: waste oil, solvents and stormwater are each registered separately.See the full permit list
- Veterinary clinicsA state facility permit, controlled substances registration at both state and federal level, and a medical waste manifest — none of which a general business license covers.See the full permit list

What do these permits involve in Hamilton County?
County Vendor's License
This is the closest thing Hamilton County has to a general business registration, and it is the county record that reaches the widest range of businesses: any operation making taxable retail sales from a fixed location registers with the County Auditor at 138 East Court Street in Cincinnati before making sales, whether the address is in Cincinnati, a village or an unincorporated township. The amount is statutory rather than county-set. ORC 5739.17(A) requires the applicant to pay into the county treasury 'a license fee in the sum of fifty dollars for each fixed place of business in the county that will be the situs of retail sales', and directs the auditor to transmit twenty-five dollars to the Treasurer of State for the organized crime commission fund and credit the remaining twenty-five to the county general fund — so the $50 is a combined state and county figure, and the $25 still widely quoted is the county's share. The current version of the statute took effect on 9 April 2025 under House Bill 366 of the 135th General Assembly, which doubled it, and the Auditor's own page prints the same $50 and asks for 'a certified check, business check, or money order for $50.00 for a Vendor's License'. Application is on Ohio Department of Taxation form ST-1 and may also be filed through the Ohio Business Gateway. Two statutory details matter for this site's industries: ORC 5739.17(C) provides that for a vendor with no fixed place of business 'each vehicle intended to be used within a county constitutes a place of business for the purpose of this section', which is what makes a food truck a taxable place of business; and a transient vendor with no fixed place of business in the county takes a $50 transient vendor's license from the Tax Commissioner under ORC 5739.17(D), a state registration rather than a county one. A holder of a Division of Liquor Control permit must hold the vendor's license 'in the identical name and for the identical address as shown on the permit', and the license is displayed in clear sight of the public. Collision, auto glass, airbag, paintless dent, window tint and mobile repair operators need this license twice over: ORC 4775.07(A) makes a valid vendor's license issued under ORC 5739.17 a condition of the state motor vehicle repair registration. One caution about the county's own business pages: the item labelled Vendor Registration on them leads to the county's procurement bid portal for suppliers selling to the county, which is a different thing from this sales-tax license.
Plumbing Permit (commercial and residential)
Almost every fit-out in the Hamilton County General Health District meets this permit, because it is charged per fixture rather than as a flat sum: a restaurant kitchen with a three-compartment sink, hand sinks, a mop sink and floor drains, a salon with shampoo bowls and pedicure stations, a veterinary clinic with prep and kennel-area plumbing, a childcare centre with child-height fixtures. The pricing shape is worth planning around — the first, new or replacement fixture is $61.00 and each additional fixture $22.00, so the count drives the bill, and the $61.00 minimum permit fee is the floor for small work. Separate lines cover the things a fit-out often forgets: $30.00 per backflow device, $60.00 for a water heater replacement, and $61.00 for a water or sewer line up to 250 feet plus $1.00 for each additional 10 feet. Plan review is banded by fixture count from $50.00 to $150.00, with a $500.00 expedited option, and the schedule notes that digital submission avoids the per-sheet scanning charge. Permits are issued to contractors who are registered and bonded with the Plumbing Division, which HCPH requires before work starts, and repair or replacement work counts: the programme covers installation, construction, alteration and repair including replacement fixtures. A build-out can also draw in two other bodies at once, because Plumbing Regulation 3-2025 assigns pressure forced mains for sanitary sewage and certain sewer and water work to the Metropolitan Sewer District of Greater Cincinnati, and water service lines for fire protection to the building department — so the same project can carry an HCPH plumbing permit, an MSD approval and a county building permit. Inside Cincinnati, Norwood or Springdale the city health department or city plumbing inspection office handles this instead.
Smoke Free Workplace Compliance (HCPH enforcement)
Hamilton County Public Health's Codes and Regulations page lists the Smoke Free Workplace Program, OAC Chapter 3701-52, among the codes its Environmental Health Division operates under, and its Environmental Health page links the Ohio Department of Health's programme; this is an enforcement and complaint function, so there is no county license to apply for and the county charges no fee for it. It is recorded here because it is a real operating condition for every enclosed public place and place of employment in the county — a restaurant, cafe, shop, gym, salon, repair shop, veterinary practice or childcare centre — and because the practical duties that go with it are easy to miss: posting no-smoking signage, removing ashtrays and receptacles from the enclosed area, and dealing with complaints when they are referred. Enforcement runs on complaint rather than on inspection rounds, and the rules that define a public place, a place of employment and the exemptions are state rules in OAC Chapter 3701-52 rather than county ones, so the substance does not change from one Ohio county to the next. What does change locally is who takes the complaint, and in the Hamilton County General Health District that is HCPH's Environmental Health Division.
Commercial Building Permit (Ohio Building Code)
Two things decide whether this record applies at all. The first is geography: Buildings + Inspections states that it 'is responsible for issuing building permits in the unincorporated townships of Hamilton County and in six contract jurisdictions', and the county's development-process page names them — 'Amberley Village, Elmwood Place*, Indian Hill, North Bend and Terrace Park*, and Wyoming*' — with the footnote '*Commercial permits only', so in Elmwood Place, Terrace Park and Wyoming the county issues the commercial permit but not the residential one. The division's own jurisdiction map, dated 05/22/2026, puts that in proportion: Cincinnati 79.72 square miles, individual municipalities 69.81, county commercial-only 2.88 and county full jurisdiction 260.19. Every other city and village runs its own building department. The second is sequence: the same page states that 'A Zoning Certificate from the local zoning authority is required before an application for a building permit can be submitted', and electrical work is separate because 'Electrical permits and electrical inspections are handled by Inspection Bureau, Inc.' The fee is computed rather than looked up, and a reader who budgets from a percentage of construction value will be wrong — the formula multiplies gross area by $143.68, then by a construction-type factor for the use group, then by a small permit fee multiplier, with an extra 1.25 where HVAC is included in the same permit. The use group matters as much as the size: a restaurant is A-2 assembly at 1.27 down to 0.93, a shop is M mercantile at 0.97 down to 0.63, an office or clinic is B business, and a childcare centre is I-4 at 1.22 down to 0.87. Below the formula sits a floor: $653.23 is both the up-front payment and the minimum building fee for a new building, an addition or a whole-building alteration, and $705.49 is that up-front figure with the 5 per cent technology fee and the 3 per cent state surcharge added. Smaller jobs have their own minimums — $474.01 for minor alterations as the Building Official determines them, and $318.28 for a kitchen exhaust hood, which is the line a restaurant fit-out meets most often. The penalty for skipping the permit is severe and stated on the schedule: the permit fee plus a 200 per cent penalty. Violations are separately punishable by a fine of not more than $300 per offence under ORC 307.37 and 307.99(C), rising to not more than $1,000 for offences against ORC Chapters 3781 and 3791.
Commercial Certificate of Occupancy (Ohio Building Code)
The certificate is the last gate before a business can open in the county's building jurisdiction, and it is cheap compared with what it depends on. The Buildings + Inspections fee schedule's administrative fees paragraph prices it directly: 'Buildings and structures regulated by the OBC - $189.62 ($204.79 with surcharge and technology fee included)'. Residential work under the Residential Code of Ohio is $58.44 ($61.94 with fees), and where a certificate of occupancy is not required a Certificate of Completion of Permit is $32.46. Occupying a commercial building without the certificate costs $588.29 on top of the certificate itself, and occupying without a temporary certificate carries the same $588.29 in addition to the temporary certificate fee — which is the most expensive mistake on this page, because it is the one a tenant makes by moving equipment or staff in a few days early. Two approvals outside the building department gate the certificate, and both should be started early. The county's development-process page states that 'Applicants must obtain a Sewer Tap and Inspection before a building Certificate of Occupancy can be issued', and that 'Applicants requiring a new or upgraded service must obtain a Water Tap and Inspection before a building Certificate of Occupancy can be issued' — the first through the Metropolitan Sewer District, the second through Greater Cincinnati Water Works, each with its own service exceptions. Electrical sign-off comes through Inspection Bureau, Inc. rather than the county. The certificate is issued for a use of a building or space, which matters on a change of tenant in the same use group, and a temporary certificate buys 30 days at a time while outstanding items are closed out.
Electrical Permit and Inspection (performed by Inspection Bureau, Inc. for the county)
This is the step that surprises people building out a unit in unincorporated Hamilton County: the electrical work does not go through the county at all. The county's own development-process page states that 'I.B.I. (Inspection Bureau, Inc.) reviews and inspects all electric plans on behalf of the Building and Inspections Division of the Planning and Development Department as well as the City of Cincinnati and over thirty other municipalities', and that electrical permits must be applied for separately from the building permit. The practical consequences are scheduling ones. The electrical application is a second filing with a second body, on its own timetable, and the county's building inspections and the Certificate of Occupancy depend on the electrical work being signed off, so a fit-out that treats electrical as part of the building permit loses time at the end of the job rather than the start. No electrical figure is published on the county's page or on the Buildings + Inspections fee schedule, which prices building, HVAC and fire-protection work only; the amount comes from Inspection Bureau, Inc. when the separate application is made. A restaurant adding hood and refrigeration circuits, a salon adding stations, a repair shop adding lifts and compressors and a childcare centre changing a unit's use will all meet this step in addition to the county permits recorded here.
Zoning Certificate — new tenant, commercial alteration or facade change
The new tenant line is the one that catches an ordinary change of occupant — a restaurant, salon, fitness studio, childcare centre or repair shop taking over an existing unit — and whether it costs $163.80 or $423.15 turns on one question: whether the change requires a parking analysis. The county's zoning fee schedule for 2026, updated 11/19/2025, prices a new tenant with no parking analysis at $163.80 and commercial alterations, facade changes or a new tenant requiring a parking analysis at $423.15, each figure already including the $46.00 inspection fee and the 5 per cent technology fee. Before using either, establish which zoning authority the address answers to, because the county administers only one of three regimes. The county's own page states that 'Zoning in Hamilton County is broken into three general categories of jurisdiction: zoning adopted for cities or villages, zoning adopted for townships under township trustee jurisdiction, and zoning adopted for townships under county commissioner jurisdiction', and that Development Services handles the third, covering 'all of Columbia and Harrison Townships and the majority of Green and Miami Townships', plus 'the Village of North Bend and Symmes Township' by contract with the Regional Planning Commission. Anderson, Colerain, Crosby, Delhi, Springfield, Sycamore and Whitewater Townships zone through their own trustees under ORC Chapter 519, and each of the county's 37 cities and villages zones for itself. Sequence matters: the county's development-process page states that a zoning certificate from the local zoning authority is required before a building permit application can be submitted, so this is the first county filing on most fit-outs, and Hamilton County Public Health separately requires written zoning approval before it will license a body art facility. Where the use is not permitted outright, the Board of Zoning Appeals route applies instead, at a materially higher fee.
Board of Zoning Appeals — Conditional Use, Variance or Appeal
Several of the industries on this site are conditional uses rather than permitted ones in a county-zoned township, and a childcare centre, a veterinary clinic with boarding, a repair shop or a gym in a district that does not list the use outright ends up here rather than at the zoning counter. The cost is the largest single county application fee a small business is likely to meet: $948.00 plus $198.00 for each acre pertaining to the conditional use area, so the acreage of the parcel involved, not the floor area of the unit, drives the number. Modifying an approval already granted is $764.00, which is the line to use when an existing conditional use changes rather than starting afresh. Commercial variances are priced on the value of the improvements in four bands from $948.00 to $3,784.00, and an appeal against an administrative official's decision — the route when a zoning certificate is refused — is $579.00, with the refusal letter itself $129.00. Two operational points from the schedule are worth reading before filing. Processing fees are non-refundable and cheques are payable to the Hamilton County Treasurer, so a speculative application is a sunk cost. And the Board reserves a penalty: it 'may invoke a penalty fee of up to two times the application fee when a project is commenced prior to obtaining an approval', which is a doubling on top of the building department's own 200 per cent penalty for work started without a permit. The jurisdiction is the same as for zoning certificates — the county commissioner zoning jurisdiction covering all of Columbia and Harrison Townships, most of Green and Miami Townships, and North Bend and Symmes Township by contract; elsewhere the township's own board of zoning appeals or the municipality's hears the case.
Earthwork (Sediment and Erosion Control) Permit — commercial
Any earth-disturbing work for a commercial building or a parking area in unincorporated Hamilton County needs this sediment and erosion control permit from the Hamilton County Conservation District, and the county lists the Earth Movement Permit and the Soil and Water Conservation District among its own business permits. The one-acre threshold changes the shape of the charge completely. Below an acre, plan review is a flat $159.90 for a new building or a retaining wall and $106.60 for a shell, an addition, an accessory structure, a footing and foundation, a temporary structure or a demolition. At one acre or more, plan review becomes $159.90 per acre with a $1,000 minimum, and a $639.62 inspection fee covering twelve inspections is added, because the schedule requires monthly inspections for projects at or above an acre or forming part of a common plan of development — so a project that crosses the threshold by a fraction of an acre pays several times what it would have below it. A 5 per cent technology fee is assessed on all applications. The regulations behind the permit were adopted by the Board of County Commissioners on 1 November 1990 and run through the district's 2019 Rules and Regulations Article III. One provenance note belongs with these figures: the fee sheet the district links today from its own earthwork page carries the year only in its file name and prints no adoption or effective date on the sheet itself, so the figures are quoted as the schedule the district currently publishes rather than as a dated adoption. Site work sequencing matters as much as the fee: the county's development-process page places the earthwork permit, a Stormwater Drainage System or floodplain approval and a County Engineer driveway permit before the building permit, not after it.
Stormwater Drainage System Review and Inspection (and Special Flood Hazard Area permit)
A new commercial building, a new car park or an expansion in unincorporated Hamilton County that adds storm sewer structures, pipe or a detention basin goes through Stormwater + Infrastructure, and the minimum total of $1,311.00 makes this the most expensive site-work review the county charges on a small project. The components are itemised — $125 per storm sewer structure, $2 per linear foot of pipe 12 inch or greater and $624 per detention or retention basin, with a $624 minimum inspection fee, a review fee of 20 per cent of the inspection fee and a 5 per cent technology fee on top — and the sheet explains the derivation, stating that the figures are based on $66 an hour for review and $61 an hour for inspection with additional inspection billed as needed. What the fee buys is unusually broad and worth knowing before treating it as a plan-check charge: the pre-development review meeting, improvement plan review, flood study information, design calculations review, review of detention easement plats and as-builts, the pre-construction meeting, all inspections of public and private storm drainage systems, bonding through punch list, and inspections for one year after the subdivision record plat is recorded. Two things are outside it — review of a HEC-RAS study and any revision after the final improvement plan is approved. The same office administers floodplain management and the Special Flood Hazard Area permit the county lists among its business items, publishing the FEMA elevation certificate, no-rise certification and non-residential dry floodproofing certificate forms, so a business locating in a flood hazard area meets this office even without new drainage work. One provenance note: the retrieved PDF's embedded title metadata carries an older year than the sheet body, which prints effective 1 January 2025; the printed sheet is what is quoted here.
Sewer Tap and Water Tap Before a Certificate of Occupancy
These two utility approvals gate the Certificate of Occupancy, and the county's development-process page states both in terms: 'Metropolitan Sewer District of Greater Cincinnati (MSDGC) provides sanitary sewer service to most of Hamilton County (exceptions include Glendale, Indian Hill, Terrace Park, Harrison, Harrison Township, Whitewater Township). Applicants must obtain a Sewer Tap and Inspection before a building Certificate of Occupancy can be issued.' And: 'Greater Cincinnati Water Works (GCWW) provides Water service to most of Hamilton County (exceptions include, Glendale, Indian Hill, Addyston, Cleves (including Western Miami Township and most of Whitewater Township), Portions of Harrison Township, Harrison, Loveland and Wyoming). Applicants requiring a new or upgraded service must obtain a Water Tap and Inspection before a building Certificate of Occupancy can be issued.' The practical reading is that a fit-out needing a new or upgraded water service, or any new sewer connection, has two more inspections standing between finished construction and a lawful opening, each with its own queue, and the exception lists matter because an address in Indian Hill, Glendale or Terrace Park deals with a different provider. No fee for either tap is published on the county's page: MSD's Development Services page asks applicants to 'contact Development Services by phone to verify fees before making a payment', and the water tap amount is set by Greater Cincinnati Water Works. Where the premises is not on public sewer at all, the Hamilton County Public Health on-site sewage treatment system permit applies instead, and that one is priced.
