Property Value Assessment Process in Ross County

If you live in Ross County, Ohio, understanding how your property is assessed can help you manage your property taxes and make sure you’re paying a fair amount. Many homeowners don’t realize how the county determines property values or what steps to take if they believe their home is overvalued.

This guide explains each stage of the Property Assessment Process in Ross County, what it means for you, and how you can take action if necessary.

What Is the Property Assessment Process?

A property value assessment is the official review of your home or land’s market worth, conducted by the Ross County Auditor’s Office.

The purpose of this assessment is to determine your property’s fair market value, which is then used to calculate the amount of property tax you owe.

Each property in Ross County is reviewed on a regular schedule to ensure that its assessed value reflects current real estate market conditions and maintains fairness across all property owner

Step 1: Data Collection and Property Review

The assessment process begins with data collection. The Ross County Auditor’s Office keeps detailed information about every property in the county, including:

• Lot size and location
• Type of structure (residential, commercial, or agricultural)
• Year built and total square footage
• Improvements or renovations
• Recent sales of similar nearby properties

When necessary, field appraisers from the Auditor’s Office may visit properties to confirm updates, additions, or structural changes.

Your role:
Help keep your property records accurate. If you make improvements, demolish a structure, or split or combine land parcels, notify the Ross County Auditor’s Office to ensure your property is valued correctly.

Step 2: Determining the Market Value

After collecting property data, the Ross County Auditor’s Office estimates your property’s market value — the price your home would likely sell for in a normal, open-market transaction.

To calculate this, the county uses a mass appraisal system that applies three main methods:

• Sales Comparison Approach: Compares your property to recent sales of similar homes in the same neighborhood.
• Cost Approach: Considers how much it would cost to rebuild the property, minus depreciation.
• Income Approach (for rental or commercial properties): Evaluates how much income the property could generate.

Your role:
You can review and compare your home’s market value with similar properties online using the Ross County Auditor’s Property Search tool

Step 3: Calculating the Assessed (Taxable) Value

Once the market value is determined, the Ross County Auditor’s Office calculates your assessed value, which is the portion of your property’s market value that is subject to taxation.

In Ohio, the assessed value is 35% of the property’s market value.

Example:
If your home’s market value is $180,000, your assessed (taxable) value will be $63,000.
Your property tax is then calculated based on that assessed amount, multiplied by the local millage rate — the tax rate approved by voters to fund public services such as schools, safety, and infrastructure within Ross County.

Step 4: Reappraisal and Triennial Updates

Property values in Ross County are not permanent. Under Ohio law, counties must regularly update property values to ensure assessments stay fair and reflect true market conditions.

There are two main valuation cycles:

• Sexennial Reappraisal (Every 6 Years): A complete, in-person reinspection of all properties to determine their current market value.
• Triennial Update (Every 3 Years): A statistical adjustment based on recent property sales data — no on-site inspection required.

These updates help ensure that Ross County property values remain consistent with current market trends.

Your role:
Watch for reappraisal or value update notices from the Ross County Auditor’s Office. Review your notice carefully, and if you believe your property value is too high, gather supporting evidence (such as recent comparable sales or property condition details) to file a formal complaint.

Step 5: Understanding Special Adjustments

At times, property values may change outside the regular reappraisal or update cycles. The Ross County Auditor’s Office can make special adjustments when certain property changes occur, such as:

• Adding new construction, like a room, garage, deck, or pool
• Removing or demolishing a structure
• Experiencing damage from fire, storm, or flooding
• Changing the property’s classification (for example, from residential to commercial, or vice versa)

Your role:
Promptly report any major changes to your property to the Ross County Auditor’s Office. Keeping your property information current helps ensure your tax bill remains accurate and fair.

Step 6: Review Your Assessment Notice

After the Ross County Auditor’s Office completes the property assessment process, you’ll receive an assessment notice in the mail. This document includes:

• Your updated market value
• The new assessed (taxable) value
• An estimate of your upcoming property tax amount

Your role:
Read your notice carefully. If you agree with the new valuation, no further action is required.
If you believe your property value is inaccurate or unfair, proceed to the next step filing an appeal with the Ross County Board of Revision.

Step 7: How to Appeal Your Property Value

If you believe your property has been overvalued, you have the right to file a formal complaint with the Ross County Board of Revision.

Appeal Process Overview:

1. File a complaint by March 31 of the tax year in which you receive your assessment notice.
2. Provide supporting evidence, such as:
   • Recent sale prices of similar properties in your area
   • Photos showing the property’s current condition
   • An independent appraisal report or contractor estimates for damage/repairs
3. Attend a hearing (in person or virtually) to explain your case and present your evidence.
4. The Ross County Board of Revision will review your complaint and issue a written decision regarding any value changes.

Your role:
Prepare your evidence early and submit your appeal before the March 31 deadline. If your appeal is approved, your assessed value — and therefore your property taxes — will be reduced accordingly.

Step 8: Apply for Exemptions or Credits

Even after your property’s assessed value is finalized, you may qualify for property tax reductions in Ross County.

Common programs include:

• Homestead Exemption: Available for homeowners 65 or older or those who are permanently disabled.
• Owner-Occupancy Credit: For residents who live in their primary residence.
• Veteran or Disability Exemptions: For qualifying military veterans and their spouses.

Your role:
Check your eligibility each year and submit the required exemption or credit forms through the Ross County Auditor’s Office to reduce your property taxes.

Step 9: Stay Informed and Monitor Your Property Record

The Ross County Auditor’s website allows you to:

• Search for your property by owner name, address, or parcel number
• View your property’s market and assessed value
• Estimate your taxes using the available Tax Estimator tool
• Track updates, appeals, or exemption filings

Regularly reviewing your property record helps ensure your information stays accurate and that your tax payments remain fair.
