Who Keeps Rock Island County Property Records?

Public access to Rock Island County property records is governed by the Illinois Freedom of Information Act (5 ILCS 140). The responsibility for keeping these records is distributed across these three county offices:

• The Supervisor of Assessments equalizes township-level assessments to the statutory 33.33% ratio, administers homestead exemptions, and serves as Clerk of the Board of Review during the appeal season.

• The Recorder of Deeds maintains the public chain of title for Rock Island County. As a separately elected position, the Recorder operates independently from the County Clerk's office.

• The County Treasurer bills property taxes each May, processes payments, conducts the annual tax sale for delinquencies, and oversees owner redemptions after a sale.

How to Search Rock Island County Property Records Online

Online property research in Rock Island County requires moving across three portals, as outlined below:

1. Begin with the Rock Island County Assessor portal. Searches may be conducted using an address, owner name, and PIN. Each result reveals current ownership, the assessment value, characteristics like square footage and year built, recent sales prices, and any homestead exemptions filed.

2. Check the tax record at the Rock Island County Treasurer portal. The Treasurer’s database shows current and past tax bills, the taxing-district breakdown, payment status, and any delinquency or active refund.

3. Recorded documents are available through the Recorder of Deeds’s portals. The portals accept searches by party name, document number, PIN, or recorded date. Free guest searches show the index. Full images often require a pay-per-search or subscription option.

4. Trace ownership history by working backward from the current deed. The grantor on each deed should be the grantee on the one immediately before it. A break in that chain often signals a missing document worth flagging for a title professional.

5. The county GIS portal handles mapping needs. Parcel boundaries, zoning overlays, FEMA flood zones, and an aerial imagery layer are on a single interactive map.

Foreclosure and the Annual Tax Sale

Illinois separates mortgage foreclosure from tax-delinquency foreclosure. Mortgage cases (judicial only in Illinois) are handled through the Rock Island County Circuit Court under 735 ILCS 5/15-1101 et seq.. Tax-sale cases are handled by the Treasurer's Office under the Property Tax Code at 35 ILCS 200, Article 21.

Annual tax sale

The Rock Island County Treasurer holds an annual tax sale for prior-year unpaid taxes. Tax buyers compete by bidding the penalty interest rate downward from a 9% statutory maximum. The lowest bidder wins a tax certificate, which is a lien rather than ownership.

Right of redemption

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

Scavenger sales

A scavenger sale runs every two years under 35 ILCS 200/21-145 for properties that have been delinquent three or more years and did not sell at the annual tax sale. Bidding is on the dollar amount rather than the penalty rate.

Costs to Access Property Records

Online access to property records in Rock Island County is usually free. Paper copies and certified copies are subject to per-page fees set by the county, while new recordings follow Illinois's Predictable Fee Schedule.

The Predictable Fee Schedule applies in Rock Island County under 55 ILCS 5/3-5018.1. Documents are categorized into five classes. These include deeds, mortgages, leases, miscellaneous items, and non-conforming items. Each class attracts a flat fee, while non-conforming filings incur a doubled fee.

In addition to the recording fee, Illinois imposes a state real estate transfer tax of $0.50 per $500 of consideration. Rock Island County adds another $0.25 per $500.

How to Record a Document

A quitclaim deed, a release of mortgage, or a personal lien can be filed with the Rock Island County Recorder's office by doing the following:

1. Confirm the document meets Illinois formatting under 55 ILCS 5/3-5018.2. Use 8.5" by 11" white paper of 20-lb weight or better, printed in black ink, with half-inch margins. Leave a clear 3" by 5" area in the upper-right corner of the first page for the recording stamp.

2. Look up the recording fee on Rock Island County's Predictable Fee Schedule. The fee is flat per document class. Non-conforming filings (poor formatting, wrong paper, missing PIN) get charged at double the standard rate.

3. If the document transfers property, file the PTAX-203 transfer declaration through MyDec at the same time as the deed. MyDec is the state Department of Revenue's online system. The filing produces a stamp number that the Recorder ties to your document.

4. Three filing options are available. Walk-in submission at 1504 3rd Ave, 2nd Floor, Rock Island, IL 61201, mail-in filing (include payment and return envelope), or e-recording through approved vendors like Simplifile or CSC. Once recorded, the document gets a permanent recording number and enters the public index.

The Recorder assigns a permanent document number at filing, which is the fastest lookup parameter for any future certified copy request or title research.
