Aurora Property Records Search

Aurora property records are split across three counties. Most of the city falls in Kane County, but parts extend into DuPage County and Will County. This makes Aurora unique in Illinois. You need to know which county your parcel sits in before you can look up records or file an appeal. Each county runs its own assessor's office with its own search tools and fee schedules. This page breaks down how to find Aurora property records no matter which county your property is in.

Kane County Property Records for Aurora

The bulk of Aurora sits in Kane County. If your address is on the Aurora side of Kane County, the Kane County Assessment Office handles your property records. You can reach them at (630) 208-3818. The office is inside the Kane County Government Center in Geneva. Staff there set assessed values, process exemption forms, and handle first-level appeals for Aurora parcels in Kane County.

The Kane County property search portal lets you look up any parcel by address, owner name, or PIN. This is the fastest way to pull up Aurora property records for the Kane County portion of the city.

Use PIN lookup tools to find which county handles your Aurora parcel and get the right assessment office.

Under 35 ILCS 200/, all property in Illinois must be assessed at 33 1/3 percent of fair market value. Kane County follows a quadrennial cycle, meaning reassessments happen every four years. When your area comes up, the assessor reviews sales data, building permits, and market conditions to set new values. You get a notice in the mail with your updated assessment.

DuPage County Property Records for Aurora

Parts of Aurora extend into DuPage County. If your parcel is on the DuPage side, the DuPage County Supervisor of Assessments handles your records. Call them at (630) 407-5858. DuPage uses its own search system and has its own appeal deadlines. Do not mix up the two. Filing with the wrong county will not help you.

The DuPage County property lookup tool covers all parcels in DuPage, including those in Aurora. You can search by address, PIN, or owner name. The tool shows assessed values, tax history, exemptions, and sales data. It is free to use and does not require a login.

DuPage County also follows the quadrennial assessment cycle. But the reassessment years may differ from Kane County. So your Aurora property in DuPage might be reassessed in a different year than a neighbor across the street in Kane County. That is one of the complications of living in a city that spans three counties.

Will County Property Records for Aurora

A small section of Aurora falls in Will County. The Will County Supervisor of Assessments can be reached at (815) 740-4648. If your Aurora address is in Will County, your assessment, exemptions, and appeals all go through Will County offices. The Will County system is separate from both Kane and DuPage.

Will County has its own online search tools for property records. You can check your assessed value, look at tax bills, and see if any exemptions are on file. The county seat is in Joliet, so if you need to visit in person, that is where you will go. Most Aurora property owners are in Kane County, but it pays to check if you are near the southern edge of the city.

Aurora Property Tax Records

Property taxes in Aurora are paid in arrears. The bill you get covers the prior year's assessment. Because Aurora spans three counties, tax bills come from three different county treasurers. The process works the same in each case. The assessor sets the value. Local taxing bodies set the rates. The treasurer sends the bill and collects payment. Schools take the largest share of the tax bill in all three counties.

Tax rates in Aurora vary by location. Two houses a block apart can have different rates if they sit in different school districts or park districts. The total rate is the sum of all overlapping taxing districts. Check your tax bill to see the full breakdown. If you think your assessed value is too high, appeal to the assessor in your county. If you have a billing question, call the treasurer.

The lien date under Illinois law is January 1 each year. That date sets who owns the parcel and what condition it is in for tax purposes. Any changes after January 1 apply to the next tax year.

Aurora Property Tax Exemptions

Aurora property owners can apply for exemptions to lower their tax bill. The forms go through your county's assessor office. Since Aurora is not in Cook County, the exemption amounts differ from Chicago. The General Homestead Exemption cuts $6,000 from your assessed value. That is the standard amount for non-Cook County areas in Illinois.

• General Homestead Exemption: $6,000 reduction
• Senior Citizens Homestead Exemption: $5,000 (age 65+)
• Senior Citizens Assessment Freeze: locks value for qualifying seniors
• Disabled Persons Homestead Exemption: $2,000 reduction
• Disabled Veterans Homestead Exemption: varies by VA rating
• Returning Veterans Homestead Exemption: $5,000 one-time break

You must own and live in the home to qualify for homestead exemptions. File with the assessor in whichever county your parcel is in. Forms are usually due by a set deadline each year. Check with Kane, DuPage, or Will County for the current dates.

Appeal Aurora Property Assessments

If your Aurora property records show a value that seems too high, you can appeal. The process depends on which county your parcel is in. In Kane County, file your appeal with the Kane County Board of Review. In DuPage, go through the DuPage County Board of Review. In Will County, the Will County Board of Review handles it. Each board has its own filing window and forms.

Bring comparable sales data when you file. The board looks at what similar homes sold for in your area. You do not need a lawyer. The process is free. If the board does not rule in your favor, you can take the case to the Illinois Property Tax Appeal Board or circuit court. Most homeowners handle the first appeal on their own without much trouble.

Aurora Building and Permit Records

The City of Aurora Building Division handles permits for construction, renovation, and demolition within city limits. Call (630) 256-3080 for questions about permits. Building permits can affect your property records because new construction or major work may trigger a reassessment. When you pull a permit, the assessor's office in your county will eventually review the change and update your assessed value.

The Illinois Department of Revenue property tax page provides statewide guidance that applies to Aurora and all other Illinois cities. The state does not manage property taxes directly but sets rules that local offices follow.

The state-level page covers assessment rules, equalization factors, and links to local offices across Illinois.
