Buying a lot in a subdivision near Genoa? What you want is the Sycamore plat map, since it shows lots, streets and easements as approved. In this Sycamore guide: where to request a copy, plat versus tax map, and the details that matter to buyers.
The Sycamore plat map: start here
For a lot in Sycamore, the deed usually cites the plat; bring that to the recorder's office or its online index.
The free map to start with
The public parcel map for this area is the DeKalb County GIS Web Base, and anyone can open it without signing up. For property near Maple Park, type a street address, an owner's name or a parcel number, and the matching parcel lights up. For property near DeKalb, write down the parcel ID while you have it open; each clerk in the county will want it.
A word on accuracy
The acreage figure is an estimate; only a licensed surveyor establishes the real lines for a parcel near Kirkland. Out toward Maple Park, records update in batches, so a deed recorded last month might lag behind.
When there's no plat
Rural land near Malta that was never subdivided is often described by metes and bounds or survey description; the deed and any recorded survey describe it instead.
A quick look at the area

Sycamore, IL: the basics

For acreage around Kirkland, city or town hall handles things like zoning, permits and utilities within town limits, but the county runs assessment and recording. Land beyond the town limits toward Malta generally follows county rules instead.
Using it on a phone
The parcel map usually runs in a mobile browser, which helps when you're standing on land near DeKalb, though signal can drop in rural spots. A saved image of the lot near Maple Park and its lines is a good backup.
Plat map vs. parcel map

What a plat shows

Building or septic questions for a lot near Cortland are for the local planning and health departments, depending on whether the land is inside town limits.
Deeds, plats and who keeps them
The map is an index, not the title: deeds, plats and easements for land near Malta are filed with the county Recorder of Deeds (in many counties the County Clerk and Recorder). Inherited tracts around Genoa can go back through several deeds, and a title company is worth hiring if money is changing hands.
