Carroll County, IL Property Records: Search Deeds, Owners, Tax Records, and Maps

If you are searching property records in Carroll County, three county offices keep the information you need. The Recorder of Deeds is separately elected, the Supervisor of Assessments handles parcel data, and the Treasurer handles tax bills. The system covers roughly 9,000 square miles in the county.

Homes in Carroll County generally sell within 70 to 100 days of listing, slower than the statewide median. The housing market is dominated by single-family detached homes in Mt. Carroll, Savanna, and Lanark. The Mississippi River forms the western border, with Mississippi Palisades State Park anchoring the southwest corner. Housing stock skews older, with many homes built between 1890 and 1940. Working farmland fills most of the unincorporated areas.

Recent records reveal the underlying factors influencing the local real estate market, with a median home value of {median_home_value} and median rent of {median_rent}, alongside a median household income of {median_household_income} and a median real estate tax rate of {median_real_est_tax}, serving as a percentage of the property's assessed value.

Who Keeps Carroll County Property Records

In Carroll County, three elected offices manage property records, with the Freedom of Information Act at 5 ILCS 140 governing public access. The Property Tax Code at 35 ILCS 200 governs assessment and collection. Here is how the three offices divide responsibility:

• The Supervisor of Assessments values every parcel in the county, administers homestead exemptions, and maintains the parcel database used by the Treasurer and the Board of Review.

• The Recorder’s office houses all recorded real-estate documents in Carroll County. The Recorder of Deeds is its own elected office, separate from the County Clerk.

• The County Treasurer handles the tax-bill workflow end-to-end, from generation, mailing, collection, delinquency, and the annual tax sale to the post-sale redemption.

Carroll County was organized in 1839 and named for Charles Carroll, the longest-lived signer of the Declaration of Independence. Land records run back to that year.

How to Search Carroll County Property Records Online

Online property research in Carroll County involves three portals: ownership and assessment at one office, deeds and liens at another, and tax bills and payment status at a third. The following steps works for nearly every search task:

• Start at the Carroll County Assessor Property and Map Search portal. Enter the property's address, owner name, or PIN. The result page shows the current legal owner, equalized assessed value, property class, sales history, and any active homestead exemptions.

• Check tax-bill status through the Property Tax Inquiry portal. This is where you see what the property owes, what's already been paid, the breakdown by school, county, township, and municipal levies, and whether anything has gone delinquent.

• The Land Records Search portal shows the recorded chain of title. Index searches are usually free for guest users. Pay-per-search options like Tapestry handle one-off retrievals, and Laredo subscriptions handle high-volume research.

• Walk the chain of title back from the most recent recorded deed. The grantor on each older deed must match the grantee on the deed that came after. If a name doesn't line up, you've found a gap that needs research.

• For mapping and boundary work, use the county GIS portal. The map layers parcels, zoning, flood zones, and aerial imagery. Most Carroll County GIS layers are also downloadable for further analysis.

Assessor: Ownership, Values, and Parcel Data

Carroll County's assessment work runs through the Supervisor of Assessment. The office maintains parcel data, equalizes township-level work, administers exemptions, and serves as Clerk of the Board of Review during the appeal season.

Recorder of Deeds: Deeds, Mortgages, and Liens

The Recorder of Deeds in Carroll County is responsible for recording every document that touches title. Deeds, mortgages, liens, plats, easements, and similar documents pass through this office and become part of the public chain of title.

Treasurer: Tax Bills and Payments

The Treasurer in Carroll County manages everything tax-bill-related: the bills themselves, payment processing, the annual tax sale for delinquencies, and redemption from tax-buyers.

Property Tax in Carroll County: Rates, Exemptions, and Appeals

Carroll County property taxes follow the Illinois Property Tax Code structure. Assessed value targets one-third of fair market value, the state may apply an equalization factor, exemptions reduce the equalized assessed value, and then taxing-district rates produce the bill.

Homestead exemptions

Carroll County homeowners typically qualify for one or more of these statutory homestead exemptions. Each reduces taxable EAV, lowering the final tax bill:

• General Homestead Exemption: Up to $6,000 EAV reduction for owner-occupied homes (35 ILCS 200/15-175). Carroll County uses the baseline tier (applicable in most Illinois counties) under the three-tier statutory structure.

• Senior Homestead Exemption: Up to $5,000 EAV reduction for owners 65 and older under 35 ILCS 200/15-170.

• Senior Citizens Assessment Freeze: Freezes assessed value at a base year for seniors with household income at or below $75,000 (indexed to CPI from 2026).

• Disabled Veterans Standard Homestead: Tiered by VA disability rating: $2,500 EAV at 30-49%, $5,000 at 50-69%, full exemption at 70%+.

• Persons with Disabilities and Home Improvement: $2,000 EAV reduction for permanent disability; separate four-year exemption shielding up to $75,000 of improvement value.

Appealing an assessment

The appeal process in Carroll County has two steps. Start with the Board of Review by filing within 30 days of the assessment notice. If the Board denies, the next stop is the Illinois Property Tax Appeal Board, filed within 30 days of the Board's decision.

GIS Maps and Parcel Viewer

Carroll County maintains a GIS portal layering parcels, zoning, school districts, voting precincts, and floodplains over recent aerial imagery. The viewer is web-based, and most layers download as shapefiles.

• County GIS portal: The county's web GIS layers parcels, zoning, and floodplains with recent aerial imagery for Carroll County.

• Illinois Geological Survey clearinghouse: The state-level ISGS clearinghouse hosts statewide layers including soil, hydrology, and DEM data.

Foreclosure and the Annual Tax Sale

Mortgage foreclosures are judicial in Illinois and are run through the Circuit Court under 735 ILCS 5/15-1101. Tax-delinquency foreclosures run through the Treasurer's annual tax sale under 35 ILCS 200, Article 21.

Annual tax sale

Carroll County's annual tax sale is the Treasurer's mechanism for clearing prior-year delinquencies. The bid system runs in reverse, with buyers competing by accepting lower penalty interest rates, and the lowest bidder receiving the certificate.

Right of redemption

The redemption right runs about 2 to 2.5 years from the sale date. The Property Tax Code at 35 ILCS 200/21-345 sets the math. The owner pays original taxes plus penalty at the buyer's winning rate (compounded semi-annually), buyer costs, and any subsequent-year taxes the buyer has paid.

Scavenger sales

Scavenger sales target properties three or more years tax-delinquent, and that did not sell at the regular annual sale. The sale runs every two years, and the bidding format differs from the annual sale. Bidders submit cash bids on the lien rather than competing on interest rate.

Costs to Access Property Records

Carroll County adopted the Illinois Predictable Fee Schedule under 55 ILCS 5/3-5018.2. The schedule replaces per-page fees with a flat fee per document class. Five classes exist: deeds, mortgages, leases, miscellaneous, and non-conforming. Non-conforming documents pay double.

There are three categories of fees in Carroll County. Copy fees cover retrieving an existing recorded document. Certification fees cover getting a certified copy. Recording fees cover filing a new document.

Property transfers in Carroll County pay two transfer taxes: state ($0.50 per $500 of consideration) and county ($0.25 per $500). Chicago and a few of its suburbs add a municipal transfer tax; most municipalities do not.

How to Record a Document

Document recording in Carroll County follows four steps. They are the same whether you're filing a deed, mortgage release, or lien:

• Check formatting first. Illinois law at 55 ILCS 5/3-5018.2 requires 8.5"x11" white paper, 20-lb or heavier stock, black ink only, half-inch margins, and a blank 3"x5" rectangle in the upper right of the first page for the Recorder's stamp.

• Determine the fee using the county's adopted Predictable Fee Schedule. Each document class (deed, mortgage, lease, miscellaneous) has a single flat fee. Non-conforming documents pay double under 55 ILCS 5/3-5018.2, which is why step one matters.

• Property-transfer documents require a simultaneous MyDec filing of the PTAX-203 declaration. MyDec runs through the Illinois Department of Revenue. The filing generates a stamp number that goes on the deed at recording. Exempt transfers still require the MyDec filing.

• Submit the document to the Recorder of Deeds in person at 301 N Main St, Mt. Carroll, IL 61053, by mail with payment and a self-addressed stamped envelope, or through an approved e-recording vendor. Simplifile and CSC are the most common vendors. The recording process typically finishes within 1 to 3 business days.

After the document is officially recorded, the document number becomes the permanent reference. Title insurance companies, attorneys, and the Recorder's research staff all use this number to retrieve the recorded document later.
