Oak Lawn is a well-established southwest-suburban village of about 58,400 residents, sitting entirely within Worth Township. In a community this size where most lots were platted generations ago, a plat of survey brings a decades-old legal description into agreement with the property you can actually see.
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.
Oak Lawn, with roughly 58,400 residents in Worth Township, is one of the larger built-out suburbs southwest of Chicago. Deeds and finished plats of survey are recorded through the Cook County Clerk’s Recordings Division, which absorbed the county Recorder of Deeds in December 2020. Long-settled residential blocks here mean many original lot corners have been disturbed over the years by fences, garages, and additions, so a survey is often the tool that confirms exactly where a line runs. Owners typically request one before a fence or addition permit or before closing on a sale. Low-lying parcels near local drainage should be checked against FEMA Special Flood Hazard Areas within the MWRD watershed.

Older lots have often seen fences and structures added over decades, and a current plat of survey confirms how those improvements sit relative to the recorded property lines.
Buyers and lenders commonly ask for a current survey so boundary lines, encroachments, and easements are clearly documented before closing.
The Cook County Clerk’s Recordings Division records plats and related documents for Oak Lawn and all of Cook County.
