DeKalb is the largest city in DeKalb County, with about 40,000 residents and a strong university presence that shapes its housing and commercial districts. That mix of campus-adjacent neighborhoods, older platted blocks, and outlying growth makes an accurate plat of survey valuable when buying, building, or resolving a boundary question. The document pins down exactly where a parcel sits amid a varied urban fabric.
A plat of survey is a drawing, signed and sealed by a licensed Illinois land surveyor, that locates the corners and boundary lines of your lot and depicts the buildings, driveways, fences and recorded easements on the property. It is the document lenders, title companies and municipal permit desks rely on.
The Pi Surveying process — clear, sealed, and ready for your closing or permit.
Though DeKalb is the county’s biggest city, the county seat is neighboring Sycamore, where land records are kept. Plats of survey for DeKalb properties are recorded with the DeKalb County Recorder / Clerk & Recorder. The South Branch of the Kishwaukee River runs through the DeKalb area, and the county’s Special Flood Hazard Areas follow the Kishwaukee mainstem and its branches, so parcels near those corridors should be evaluated for floodplain limits. Surveyors here handle a broad range of work, from tight in-city lots and campus-area properties to larger tracts on the developing edges of the city.
No. DeKalb is the largest city in DeKalb County, but the county seat is Sycamore, where the Recorder’s office keeps land records and where plats are filed.
It can. The South Branch of the Kishwaukee runs through the DeKalb area, and mapped flood hazard areas follow it, so parcels near the river deserve a closer floodplain review.
Common triggers include buying or selling property, applying for a building permit, adding a structure, or clearing up a boundary question with a neighbor.
