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

Washington County property records cover roughly 7,000 parcels across a wide area of the county, built around Nashville. Three offices handle property records maintenance. The County Clerk doubles as Recorder of Deeds. The Supervisor of Assessments handles parcel data, and the Treasurer handles tax bills.

Washington County is located in southern Illinois, between St. Louis and Mount Vernon. The county’s housing stock is centered in Nashville, Okawville, Addieville, and New Minden, where single-family detached homes dominate the market. Houses typically spend 70 to 100 days on the market before selling.

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} as a percentage of the property's assessed value.

How to Look Up Washington County Property Records

Washington County property records may be accessed through three online resources. The property tax inquiry portal covers assessment information by name, address, or parcel number; the Washington County Treasurer’s office; and recorded documents are handled by the Washington County Clerk and Recorder.

Who Keeps Washington County Property Records

Under Illinois law, Washington County is the system of record for property in the county. Two statutes shape access. The Freedom of Information Act at 5 ILCS 140 governs which records the public can see. The Property Tax Code at 35 ILCS 200 governs assessment, tax bills, and exemptions. Three offices share the work:

• The Supervisor of Assessments appraises all real property in the county, manages exemption applications, and maintains the database that feeds the Treasurer's tax bills.

• The County Clerk and Recorder maintains the public chain of title for Washington County, including every deed, mortgage, lien, and recorded easement. Like most smaller Illinois counties, this office is merged with the County Clerk.

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

Washington County was organized in 1818 and named for President George Washington. The county was created the same year Illinois became a state.

How to Search Washington County Property Records Online

Online property research in Washington County means moving across three portals. One office handles ownership and assessment. Another handles deeds and liens. A third handles tax bills and payment status. This sequence works for nearly every search task:

1. Begin with the Washington County Assessor portal. Address, owner name, and PIN searches all work. Each result reveals current ownership, the assessment value, characteristics like square footage and year built, recent sales prices, and any homestead exemptions filed.

2. Cross-check the tax record at the Washington County Treasurer portal. The Treasurer shows current and past tax bills, the taxing-district breakdown, payment status, and any delinquency or active refund.

3. Recorded documents live with the County Clerk and Recorder. The portal accepts 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 aerial imagery layer onto a single interactive map.

Assessor: Ownership, Values, and Parcel Data

The Supervisor of Assessments' office handles property valuation in Washington County. This is the office to consult for ownership records, equalized assessed values, property class codes, sales history, and the homestead exemptions on file for a parcel.

County Clerk and Recorder: Deeds, Mortgages, and Liens

Recorded documents in Washington County run through the County Clerk and Recorder. The office handles the formal recording, maintains the searchable index, and produces certified copies on request.

Treasurer: Tax Bills and Payments

Washington County's Treasurer is the office to use for tax bills, payments, and tax-sale matters. Bills are mailed each year following the Illinois statutory schedule, and the portal handles both lookup and payment.

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

The Illinois Property Tax Code governs how Washington County calculates and collects property taxes. The basic math: fair market value × 33.33% assessment ratio × state equalization factor − exemptions = equalized assessed value, then × combined tax rate = bill.

Homestead exemptions

The main exemptions that Washington County homeowners qualify for fall into five categories. Each reduces the EAV before the combined tax rate is applied:

• General Homestead Exemption: Up to $6,000 EAV reduction for owner-occupied homes (35 ILCS 200/15-175). Washington 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

Two appeal levels exist. The County Board of Review takes initial appeals within 30 days of the notice. If the Board denies, escalate to PTAB within 30 days. Successful appeals at either level reduce the EAV and lower the bill.

GIS Maps and Parcel Viewer

Washington County publishes parcel-level GIS data along with zoning, school districts, voting precincts, FEMA floodplains, and aerial imagery. Most layers are accessible through an interactive web viewer and downloadable for analysis.

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

Illinois distinguishes mortgage foreclosure from tax-delinquency foreclosure. Mortgage cases (judicial only in Illinois) go through the Washington County Circuit Court under 735 ILCS 5/15-1101 et seq. Tax-sale cases run through the Treasurer's office under the Property Tax Code at 35 ILCS 200, Article 21.

Annual tax sale

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

Right of redemption

Owners get a redemption window of roughly two and a half years under 35 ILCS 200/21-345. To redeem, the owner pays the original taxes plus the bid penalty rate (compounding every six months) plus buyer costs and subsequent-year tax payments.

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 didn't sell at the annual tax sale. Bidding is on dollar amount rather than the penalty rate.

Costs to Access Property Records

Property-records access in Washington County is free for online searches. Paper copies and certified copies carry per-page fees set by the county, and new recordings follow Illinois's Predictable Fee Schedule.

The Predictable Fee Schedule applies in Washington County under 55 ILCS 5/3-5018.2. Documents are categorized into five classes: deeds, mortgages, leases, miscellaneous, and non-conforming, with a single flat fee per class. Non-conforming filings carry a doubled fee.

Property transfers in Washington 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

Filing a document yourself in Washington County is straightforward. A quitclaim deed, a release of mortgage, or a personal lien filing follows this four-step path through the Recorder's office:

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

2. Pull the fee from Washington County's Predictable Fee Schedule: The flat per-document-class fees replace the old per-page system. Skipping formatting requirements in step 1 doubles the fee under statute, so it's worth double-checking your document.

3. If the document transfers property, file the PTAX-203 transfer declaration via 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. Submit through one of three channels: walk-in at 101 E Saint Louis St, Nashville, IL 62263, mail-in with payment and return envelope, or e-recording through Simplifile, CSC, or another approved vendor. Most filings are recorded within a few business days.

Once recorded, the document is part of the public index. The recording number is its permanent identifier, stored with the original document for any future research, certified copy request, or title work.
