How Do I Find a Licensed Land Surveyor in Illinois?
Finding the right land surveyor in Illinois is not just about price. You need someone with an active Illinois PLS license, experience with the type of survey you need, and familiarity with your county's recorded plats and local requirements. This guide walks you through every step of finding and hiring a qualified surveyor in Illinois.
Step 1: Hire a Licensed Surveyor
In this state, only a licensed Professional Land Surveyor can certify a survey. The Illinois Department of Financial and Professional Regulation maintains the official registry of licensed professionals. Every surveyor in our Illinois directory is sourced from state licensing records. Hiring an unlicensed person to do survey work is not just risky; the resulting work has no legal standing and cannot be recorded, used in court, or accepted by lenders or title companies.
Step 2: Use Official and Professional Directories
IDFPR License Search
The IDFPR license database is the authoritative source for licensed Illinois surveyors. You can search by individual name, company name, or license number. The database shows license status, license number, and expiration date.
Illinois Association of Professional Land Surveyors (IAPLS)
The IAPLS at iapls.org is the primary professional organization for licensed land surveyors in Illinois. Their member directory allows you to search for IAPLS members by location or specialty. IAPLS members have voluntarily joined the professional organization and are typically active practitioners in the field.
Online Directories
Our Illinois land surveyor directory at /illinois/ lists licensed PLSs by county with contact information and service types. You can filter by survey type (boundary, ALTA, topographic, elevation certificate) to find surveyors who match your needs.
Step 3: Match the Surveyor to Your Survey Type
Not all surveyors specialize in the same types of work. Before contacting a firm, confirm they handle your specific survey type:
| Survey Type | Notes on Specialization |
|---|---|
| Residential Boundary Survey | Most Illinois PLS firms handle this; common and widely available |
| ALTA/NSPS Survey | Requires knowledge of ALTA standards; common in Chicago metro commercial markets |
| Elevation Certificate | Requires flood zone expertise; look for surveyors in flood-prone river counties |
| Subdivision Plat | Requires familiarity with Illinois Plat Act (765 ILCS 205/) and county plat review processes |
| Expert Witness | Some PLSs testify in boundary disputes; ask specifically about litigation support experience |
Step 4: Check Experience in Your County
Land surveying in Illinois is highly local. A surveyor who regularly works in Cook County will be familiar with the Cook County Recorder of Deeds, the Cook County Assessor parcel database, and Chicago's dense urban lot patterns. A surveyor who works in downstate rural counties will be more familiar with agricultural parcel descriptions and section-line surveys in the Public Land Survey System (PLSS).
When contacting a surveyor, ask how many surveys they have completed in your county in the past year. Local experience matters for deed research efficiency and awareness of common boundary issues in your area.
Step 5: Get Multiple Quotes
A boundary survey on a standard residential lot might cost $600 from one firm and $1,100 from another in the same county. Getting two to three quotes is the best way to understand fair market pricing for your project.
When comparing quotes, make sure you are comparing equivalent scopes of work. One quote may include monument setting while another does not. One quote may include a detailed plat drawing while another offers only a certificate. Clarify the deliverables before choosing based on price alone.
Step 6: Understand Turnaround Time
Illinois surveyors are often busy, particularly in spring and summer when property transactions and construction activity peak. Standard turnaround times are two to six weeks from order to delivery of the final survey document. If you need a survey for a real estate closing with a fixed deadline, communicate that timeline upfront and confirm the surveyor can meet it before signing a contract.
Rush surveys are available from some firms at a premium. Every surveyor in our Illinois directory is sourced from state licensing records. Search by county, compare services, and request quotes from verified Illinois PLS professionals at our Illinois land surveyor directory.
