3. Who Conducts Property Assessments in Franklin County?
3.1 Role of the Franklin County Auditor
In Franklin County, property assessments are carried out by the County Auditor’s Office.
The Auditor is responsible for ensuring all valuations follow Ohio state guidelines and accurately reflect current market conditions.
Whether it’s a residential home, commercial building,
or agricultural land,
every property is assessed under the Auditor’s direction to maintain fairness in the county’s tax system.
3.2 Staff Qualifications and Certification
The team conducting assessments includes trained and certified professionals, many of whom are licensed appraisers or field experts.
They are certified through the Ohio Department of Taxation,
with ongoing education to stay updated on market trends,
valuation methods, and legal requirements.
Their knowledge of local building standards and property behavior ensures precise and responsible assessments.
3.3 Ensuring Fairness and Accuracy
Franklin County uses a transparent and data-driven approach to assessments.
The Auditor’s team relies on verified market data, recent property sales, and—when necessary—on-site inspections.
A state-approved timeline and methodology guide the entire process.
Homeowners are also given an opportunity to review and appeal their assessment, helping ensure fairness and public trust in the system.
4. How Often Are Properties Assessed in Franklin County?
In Franklin County, properties are reassessed every three years, in line with Ohio state law.
This cycle helps ensure that each property’s value reflects real-world changes in the housing market, whether prices rise, drop, or remain stable.
For example, if you bought your home in Franklin County for $180,000 five years ago,
and since then local development—like new transit options or school improvements—has increased home demand, your property might now be worth more.
The reassessment doesn’t mean you’re being penalized—it means the system is adjusting to make sure every taxpayer contributes based on today’s market value.
Regular reassessments help prevent outdated valuations that might otherwise cause inequities in taxation.
And remember—a higher assessment doesn’t automatically mean a higher tax bill.
It simply helps distribute the tax burden more fairly among property owners,
based on what their properties are truly worth today.
5. Steps in the Property Assessment Process – Franklin County
5.1 Data Collection
The property assessment process in Franklin County begins with comprehensive data collection.
This includes details such as your property’s square footage, number of bedrooms and bathrooms, construction type, and recent upgrades.
For example, if you’ve added a new deck or remodeled your kitchen, those changes can impact your property’s value.
Trained field staff may conduct in-person visits or use aerial imagery to gather accurate, updated information.
This process is not about invading privacy—it’s about ensuring fair and accurate taxation, so you aren’t overtaxed or undertaxed.
5.2 Market Analysis
Once data is collected, assessors analyze local real estate trends.
This means looking at recently sold properties in your neighborhood that are similar in size, age, and style.
For instance, if three nearby homes sold for $250,000, your home’s assessed value will likely fall within that range.
If you live in a growing area of Franklin County with high housing demand, your property value may increase accordingly.
These changes reflect actual market conditions—not guesses—ensuring assessments are fair and up to date.
5.3 Property Valuation – Franklin County
Finally, based on collected property data and real estate market trends in Franklin County, the Auditor’s Office determines your home’s fair market value.
This value becomes your assessed value—which is then used to calculate your property taxes.
The purpose isn’t to surprise you with an unexpected figure—it’s to ensure that your tax is based on the true market value of your property.
That’s why this step is handled using verified sales data, local trends, and professional oversight to keep things fair for all homeowners.
6. How to Review or Dispute Your Property Value – Franklin County
6.1 Understanding Your Assessment Notice
Every property owner in Franklin County receives an official Assessment Notice by mail.
This document contains your updated property value and is your first opportunity to check for any errors. Review it carefully—mistakes can happen.
For example, the square footage might be wrong, or a listed improvement (like a finished basement) might not actually exist.
6.2 Informal Review Options
If something doesn’t look right, you can request an informal review by contacting the Franklin County Auditor’s Office.
Many issues—like incorrect property features or building records—can be fixed through this simple process. You’re not alone;
hundreds of Franklin County residents file informal reviews every year and successfully correct their valuations.
6.3 Filing an Appeal (Board of Revision) – Franklin County
If your concerns aren’t resolved informally, you can file a formal appeal with the Franklin County Board of Revision.
This legal process allows property owners to contest their property’s assessed value.
For instance, a homeowner in Gahanna recently appealed due to falling sale prices on their block—and successfully received a lower valuation.
6.4 Required Documents and Deadlines – Franklin County
To support your appeal, you’ll need solid evidence—such as a recent independent appraisal, photos, or sale prices of comparable properties in your area.
Appeals must be filed between January 1 and March 31 of the next year.
If you miss this window, you’ll have to wait until the following year to try again, so be sure to track these dates.
7. How Property Assessment Affects Property Taxes – Franklin County
7.1 Tax Formula Breakdown
Your Franklin County property tax is determined by multiplying your assessed property value by the effective tax rate.

7.2 Millage Rates and Local Levies
Franklin County’s millage rates vary depending on where you live—Columbus, Westerville, Grove City, and other areas all have different local levies.
These levies fund critical services such as public schools, police, EMS, libraries, and infrastructure.
That’s why two properties of equal value may receive very different tax bills.
7.3 Exemptions (Homestead, etc.)
There are tax relief options available. Franklin County offers the Homestead Exemption to senior citizens, disabled residents, and surviving spouses.
