How to 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: Verify the Surveyor Is Licensed in Illinois
Before you do anything else, verify that the surveyor holds an active Professional Land Surveyor (PLS) license issued by the Illinois Department of Financial and Professional Regulation (IDFPR). This is a non-negotiable requirement.
To check a license:
- Go to idfpr.illinois.gov
- Click on the license lookup tool
- Search by the surveyor's name or license number
- Confirm the license status is active and the license type is Professional Land Surveyor
Under the Illinois Professional Land Surveyor Act of 1989 (225 ILCS 330/), anyone who performs boundary surveys, sets monuments, or prepares plats in Illinois must hold a valid Illinois PLS license. 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 at idfpr.illinois.gov 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: Ask the Right Questions Before Hiring
Before committing to a surveyor, ask these questions:
- Is your Illinois PLS license current? (Verify independently at idfpr.illinois.gov)
- Have you done surveys on properties in my county recently?
- What does your quote include? Does it cover deed research, fieldwork, monument setting, and the final plat?
- What is your typical turnaround time for this type of survey?
- Will you provide a written quote before starting work?
- Do you carry professional liability (errors and omissions) insurance?
- Will the survey plat be signed and sealed by a licensed Illinois PLS?
Step 6: Get Multiple Quotes
Survey pricing in Illinois varies widely between firms. 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 7: 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. A rush job (under one week) may cost 25 to 50 percent more than a standard-turnaround survey.
Red Flags to Watch For
Be cautious if a surveyor:
- Cannot provide their Illinois PLS license number for verification
- Refuses to provide a written quote before starting work
- Promises unusually fast turnaround at a price well below other quotes
- Does not provide a signed and sealed plat as part of the deliverable
- Has disciplinary history on the IDFPR license lookup
