• 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 County Clerk and Recorder houses all recorded real estate documents in DeKalb County, including deeds, mortgages, liens, plats, and easements. The county combines this role with the County Clerk position.

How to Search DeKalb County Property Records Online

Search DeKalb County property records by navigating through three county portals:

1. Start your search at the DeKalb County Assessor or Supervisor of Assessments 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 active homestead exemptions.

2. Move to the Treasurer's office portal. Tax bills, payment history, and taxing-district breakdowns are all there. Delinquent parcels are flagged.

3. For the recorded chain of title, check the County Clerk and Recorder portal, which serves as the primary source. Index search is usually free for guest users. Pay-per-search options like Tapestry handle one-off retrievals, while Laredo subscriptions handle high-volume research.

4. Build the chain of title by starting at the current deed and tracing back. Each grantor in the chain should match the grantee on the previous deed. Gaps usually mean missing records that a title company will need to research.

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

Foreclosure and the Annual Tax Sale

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

Annual tax sale

DeKalb County's annual tax sale is the Treasurer's adopted method of clearing prior-year delinquencies. The bid system runs in reverse. Buyers compete by accepting a lower penalty interest rate, with the lowest bidder winning the certificate.

Right of redemption

Owners get a redemption window of roughly 2 to 2.5 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

Targeted properties for scavenger sales are those with three or more years of tax delinquency that have not been sold at the standard annual sale. The auction is held every two years. The bidding method for scavenger auctions differs from that of annual auctions, in which bidders place cash bids for the lien rather than bidding on the interest rate.

Costs to Access Property Records

Three categories of fees apply in DeKalb County. Copy fees cover retrieving an existing recorded document. Certification fees cover getting a certified copy. Recording fees cover filing a new document. The state's Predictable Fee Schedule sets the recording fee amounts.

DeKalb County adopted the Illinois Predictable Fee Schedule under 55 ILCS 5/3-5018.1. The schedule replaces per-page fees with a flat fee per document class. Five classes exist, namely deeds, mortgages, leases, miscellaneous, and non-conforming. Non-conforming documents pay double. Property transfers in DeKalb County pay two transfer taxes: state ($0.50 per $500 of consideration) and county ($0.25 per $500).

How to Record a Document

Document recording in DeKalb County is straightforward. Whether you're filing a deed, mortgage release, lien, or any other instrument affecting title, here is how to record a property document with the Recorder of Deeds’s Office:

1. Verify the document is properly formatted. Under 55 ILCS 5/3-5018.2, documents need 8.5" x 11" white paper at 20-lb or better, black ink only, half-inch margins all around, and a blank 3" x 5" space in the upper right corner of page one for the recording stamp.

2. 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 1 matters.

3. For property-transfer documents, complete the PTAX-203 through Illinois MyDec before filing. The MyDec submission produces a stamp number that goes on the deed. DeKalb County participates in MyDec like all Illinois counties.

4. Submit the document to the County Clerk and Recorder in person at Administration Building, 2nd Floor, 110 E Sycamore St., Sycamore, IL 60178, 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. Recording typically completes in 1 to 3 business days.

After recording completes, 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.
