Franklin County Building Permits, Inspections & 2026 Services
If you are building, remodeling, replacing a roof, adding a deck, installing HVAC or electrical work, demolishing a structure, or preparing a new home project in Franklin County, Ohio, the first challenge is not usually the application itself. It is figuring out which government office actually has authority over your address.
Franklin County Building Department Contact Information
| Need | Current information |
|---|---|
| Building Department | Franklin County Economic Development & Planning – Building Department |
| Building permit office | 142 S. Front Street, Columbus, OH 43215 |
| Building permits | 614-525-3166 building@franklincountyohio.gov |
| Planning / zoning help | 614-525-4872 for planning application assistance planning@franklincountyohio.gov |
| Planning & zoning mailing / office location | 150 S. Front Street, FSL Suite 10, Columbus, OH 43215 |

| In-person building meeting | The county’s current operations notice says the Building Department is open by appointment. Call 614-525-3166 before visiting. |
The two Front Street addresses can be confusing. The county’s current building-permit information directs building applicants to 142 S. Front Street, while planning and zoning materials identify 150 S. Front Street, FSL Suite 10. Use the office that matches the service you need and call first for an appointment when necessary.
Step 1: Confirm Who Has Authority Over Your Property
This is the most important step because building-code authority and zoning authority are not always the same agency.
| Property location | Where to start |
|---|---|
| Brown, Clinton, Franklin, Hamilton, Madison, Mifflin, Norwich, Pleasant, Sharon or Truro Township | Franklin County Economic Development & Planning handles county zoning compliance. Building permits may also run through the county building process depending on the project. |
| Blendon, Jackson, Jefferson, Perry, Plain, Prairie or Washington Township | These townships administer their own zoning. Obtain the required local zoning approval before or as directed for the building permit. |
| Harrisburg, Lockbourne, Minerva Park, Riverlea, Urbancrest or Valleyview | County guidance directs applicants to obtain zoning compliance from the village before applying for the applicable county residential building permit. |
| Groveport or Obetz | County residential guidance states these municipalities issue their own zoning compliance and building permits. |
| City of Columbus | Use the City of Columbus Department of Building and Zoning Services, not the county permit process. See our Columbus Building Department guide. |
| City of Bexley | Bexley operates its own Building and Zoning Department. See our Bexley building permit guide. |
| Canal Winchester | Canal Winchester currently operates its own Building Division and publishes its own building applications, permits and inspection process. |
Micro-step: verify jurisdiction before filing
- Write down the exact project address and, if available, the parcel number.
- Use the Ohio Board of Building Standards jurisdiction map to identify the responsible residential or commercial building department.
- If the property is in an unincorporated township, check the county’s official zoning information.
- If the address is close to Columbus or another municipal boundary, verify the municipality instead of relying only on the postal city.
- Only after the jurisdiction is confirmed should you create the permit application.
Which Residential Projects Need a Franklin County Building Permit?
The county’s published Building FAQ identifies the following common residential projects as work requiring building approval.
| Project | County guidance | Other approval to consider |
|---|---|---|
| New house or modular house | Building permit required | Zoning, utilities, plumbing, septic/well where applicable |
| Residential addition or interior alteration | Building permit required | Separate electrical, HVAC or plumbing permits if included |
| Deck | Building permit required | Zoning/site placement review |
| Detached garage or pole barn | Building permit required | Zoning compliance |
| Accessory structure over 200 sq. ft. | Building permit required | Zoning may apply even to smaller structures |
| Roof, siding, windows or exterior doors | County FAQ lists residential replacement work as permit work | Confirm project-specific permit category |
| Swimming pool | Building approval can apply; county says an above-ground pool does not require a building permit | Zoning compliance is still required for any pool; electrical bonding requirements may apply |
| Sunroom or porch | Building permit required | Zoning compliance |
| Move a structure | Building permit required | Site and zoning review |
| Demolition | Demolition permit required | Utility disconnection or other clearance may be required |
When in doubt, send the department a short description of the project before starting work. A small project can still require zoning, electrical, plumbing, septic, well or another approval even when a structural building permit is not required.
How to Apply for a Franklin County Building Permit Online
- Confirm jurisdiction. Make sure the county is actually responsible for your property.
- Check zoning first. Determine whether Franklin County or your township/village issues the required zoning compliance.
- Prepare plans. Have the site plan, floor plans, sections, elevations and required trade information ready before opening the application.
- Open the official portal. Go to the Franklin County Public Portal.
- Create or sign in to your account. Do not create duplicate applications when one is already awaiting review.
- Select the correct application. Choose the residential building, electrical, HVAC or applicable zoning service rather than using a similar-looking permit type.
- Enter the property and project details. Use the exact address and describe the scope clearly.
- Upload the documents. The county FAQ currently asks for one electronic drawing set in a flattened PDF format.
- Submit and monitor the portal. Staff may ask for corrections, missing documents or revised plans.
- Pay only through the legitimate county process. Current county notices warn about fraudulent development-fee invoices. Payment requests should be verified through the official portal and county contacts.
- Wait for permit issuance. A submitted application is not permission to begin regulated work.
What Plans and Documents Should You Prepare?
For a standard residential building permit, Franklin County identifies a practical set of documents that allows reviewers to understand exactly what you intend to build.
- Electronic drawing set or accepted hard-copy drawings
- Drawing index
- Foundation plan and details
- Building elevations
- Building sections
- Site plan showing the project location
- Floor plans
- Exterior wall-envelope information
- Mechanical, electrical and plumbing layout information where applicable
- Recorded deed for new house construction
- Zoning-compliance letter or certificate when required
Plans must be clear, dimensioned and drawn to a usable scale. Most routine residential drawings do not automatically have to be prepared by an architect or engineer, but the Residential Building Official can require professional or stamped documents when construction is unusual or cannot be adequately demonstrated with ordinary plans.
Deck applicants: prepare for staged inspections
The county’s official deck guide is more specific than many general permit pages. It calls for a post-hole layout, post-hole section, framing plan, framing sections, deck elevation and stair details. The published guide uses a 32-inch frost depth for normal conventional Franklin County construction.
The same guide identifies three basic deck inspection stages: footing before concrete and framing, framing after structural framing is installed, and a final inspection after the deck, stairs, handrails and guards are complete.
Open the official Franklin County Deck Permit Guide (PDF).
Zoning Compliance May Come Before the Building Permit
Building code and zoning solve different problems. Building review checks whether construction meets safety standards. Zoning determines whether the structure, use, setbacks and site arrangement are allowed on that property.
Franklin County states that a Certificate of Zoning Compliance is generally required before a change in land or building use, the construction or alteration of a structure, or certain land disturbance. Common examples include new homes, additions, pools, detached garages, sheds, fences, home occupations and similar projects.
For county-zoned townships
- Open the Franklin County EDP Forms & Applications page.
- Select the zoning application matching your work.
- Prepare the required site plan showing the property and proposed improvement.
- Submit through the Franklin County Public Portal.
- Wait for zoning review before assuming the building permit can be issued.
Franklin County Building Permit Fees
The county’s current Forms & Applications page links to an official building and zoning fee schedule. However, the linked PDF itself states an effective date of January 1, 2014. Because of that age, the amounts below are best treated as the county’s currently linked published schedule—not as a guaranteed final 2026 quote. Your portal-calculated amount or written county confirmation should control before payment.
| Published fee item | Amount shown in county-linked schedule |
|---|---|
| Building permit — first 1,000 sq. ft. | $120 base |
| Additional building area | $10 per additional 100 sq. ft. |
| Deck under 1,000 sq. ft. | $75 |
| Roof replacement | $50 |
| Siding replacement | $50 |
| Window replacement | $50 |
| Occupancy permit | $50 |
| Demolition permit | $50 |
| Electrical permit | $60 minimum in the published schedule |
| HVAC permit | $75 minimum in the published schedule |
| Initial plan review | $50; schedule notes no plan review for roof, siding and window replacement |
| Re-inspection | $75 in the published schedule |
The linked schedule also notes a 1% State of Ohio building permit surcharge. Project-specific zoning, plumbing, septic, well, plan-review or correction fees can be separate.
Practical step: submit the application first, review the fee produced by the official portal, compare it with the county’s published fee schedule, and contact staff if the amount does not make sense.
How Franklin County Building Inspections Work
The county’s online permitting system allows permit holders to request inspections and view inspection results. The exact inspections depend on the project and should follow the approved plans and permit record.
- Sign in to the Franklin County Public Portal.
- Open the permit or application associated with the job.
- Review which inspections are available or required for that permit.
- Request the inspection before covering work that must remain visible to the inspector.
- Provide accurate site-access information when requested.
- After the visit, check the portal for the inspection result.
- If an inspection is not approved, correct the listed issue before requesting another visit.
- Complete the required final inspection before treating the permit as finished.
Do not close walls, pour over required inspection areas or otherwise conceal regulated work until the appropriate inspection has occurred.
Electrical, HVAC, Plumbing, Well and Septic Permits
A building permit does not automatically cover every trade.
| Work | Where to start |
|---|---|
| Structural / residential building work | Franklin County Building Department when the property is within county building jurisdiction |
| Electrical | Separate electrical permit is required where applicable; county portal supports electrical-related permitting |
| HVAC / heating | Separate HVAC/heating permit is required where applicable; county portal supports HVAC applications |
| Plumbing / medical gas | Franklin County Public Health |
| Private well / septic | Franklin County Public Health approval is required through the applicable environmental-health process |
Franklin County Public Health currently uses Accela for plumbing and medical-gas services. Its plumbing division lists 614-525-3160 and plumbing@franklincountyohio.gov. The department says the inspection request cutoff is noon for next-day plumbing and medical-gas inspections.

How Long Does a Franklin County Permit Take?
The county publishes two timing statements that describe different parts of the process.
Building permit page: permits are described as being issued approximately 7–10 days after full plan approval for properties with access to public water and sewer.
EDP operations notice: the county also advises applicants to expect permit reviews to take at least three weeks.
Those statements are not necessarily contradictory. Plan review can take several weeks, especially when corrections are needed, and permit issuance can follow after the plans are fully approved. Private well, cistern or septic projects can take longer because Franklin County Public Health approval may be required before the building permit is released.
To reduce avoidable delay, submit a complete site plan, readable drawings, zoning approval, deed when required, and all applicable trade information the first time.
Residential vs. Commercial Building Permits
The Franklin County Building Department describes its residential role as permitting 1-, 2- and 3-family residential structures and associated development.
The county’s residential permit page states that the State of Ohio issues commercial building permits. In practice, commercial jurisdiction can also depend on whether a municipality or township has a certified commercial building department. Ohio created a statewide jurisdiction lookup specifically to solve this issue.
For a commercial project, do not assume the residential county portal is the right filing location. Enter the project address into the Ohio building department jurisdiction map first.
Building Code Used in Franklin County in 2026
For one-, two- and three-family residential construction, Franklin County currently points applicants to the 2019 Residential Code of Ohio. Ohio has amended parts of that code, including electrical provisions, so use the current Ohio rules rather than an old printed copy when a technical requirement matters.
For non-residential work, Ohio’s 2024 Ohio Building Code, Mechanical Code and Plumbing Code became effective March 1, 2024, with later amendments also adopted. The correct code depends on the building type, project scope and enforcement jurisdiction.
How to Search a Permit, Check Status or Request Building Records
If you already submitted an application, start in the same Franklin County Public Portal rather than calling immediately.
- Open the county permit portal.
- Sign in to the account used for the application.
- Open your applications or permits.
- Check status, messages, outstanding document requests and payment notices.
- Use the inspection area to view available requests and completed results.
For an older building project or information that is not available in the portal, Franklin County’s EDP Forms & Applications page provides a Public Records Request option for upcoming, active or past building projects.
Before You Submit: Five Checks That Prevent the Most Common Problems
| Check | Why it matters |
|---|---|
| Correct jurisdiction | Prevents filing with Franklin County when Columbus, Bexley, Canal Winchester or another authority actually controls the property. |
| Zoning approval | A structurally acceptable project can still be prohibited because of setbacks, use or site-placement rules. |
| Complete plans | Missing dimensions, sections, elevations or site information commonly trigger review comments. |
| Separate trade permits | Electrical, HVAC, plumbing, well and septic work can require their own approvals. |
| Final inspection | A permit is not truly complete merely because construction appears finished. |
