Winnebago County is committed to providing access to land surveying records as cost effectively as possible. In an effort to expand this access, the GIS Division is providing Plats of Survey from approximately the 1940’s to early 2000’s online. These documents have been converted from Microfiche to pdf. To access newer documents please visit the Winnebago County Planning and Zoning Department. We anticipate increased accessibility to more Plats of Survey in the future.
To view official Certified Survey Map, Subdivision Plats, and Deeds please visit the Winnebago County Register of Deeds Office or use Tapestry.
