Illinois Contractor License Lookup & IDFPR License Verification
Checking a sub's Illinois license by hand? TrackMyVendor monitors every Illinois IDFPR license daily and alerts you the moment anything changes — before it becomes a problem on your job site.

Enter an IDFPR license number to instantly check its holder, status, and expiration date.
Why a one-time IDFPR check isn't enough
An Illinois IDFPR license can move from Active to Not Renewed or Suspended without any warning to the hiring party. Roofing contractor licenses, home inspector licenses, and professional engineer licenses all renew on their own cycles — and IDFPR does not notify you when a sub's credential lapses.

Illinois contractor license requirements
Illinois uses a split licensing model: the state licenses certain professions through IDFPR, while most trades (electrical, plumbing, HVAC, general contracting) are regulated at the city or county level. Before hiring contractors in Illinois, you need to verify they hold the appropriate credential for their scope:
- A valid IDFPR license for regulated professions (roofing, architecture, engineering, home inspection, real estate, etc.)
- A city or county business license for trades not regulated at the state level (electrical, plumbing, HVAC, general construction)
- Active general liability insurance (Certificate of Insurance)
- Workers' compensation insurance (if they have employees)
- Tax documentation (W-9 forms)
For a full breakdown of which trades need which license, see our Illinois subcontractor license requirements guide.
Chicago adds a separate licensing layer
Contractors working in Chicago must comply with both Illinois IDFPR requirements and Chicago's city-specific licensing rules. The City of Chicago requires separate licenses for electrical work, plumbing, general contracting, and other trades — these are issued by the City of Chicago Department of Buildings, not IDFPR. An IDFPR license alone is not sufficient for work inside Chicago city limits.
Illinois IDFPR license types TrackMyVendor covers
TrackMyVendor pulls from the IDFPR public license database and tracks the following contractor-relevant license types.
| IDFPR License Type | Category | Relevant Trades / Notes |

| Geology | Engineering | Licensed Professional Geologist; relevant for site assessments, soil work, and environmental reports |
What IDFPR does not cover: Illinois does not issue a state-level license for general contractors, electricians, plumbers, or HVAC technicians. Those trades are licensed at the city or county level. If your sub is an electrician or plumber working in Chicago, they need a Chicago Department of Buildings trade license — not an IDFPR credential.
What Illinois IDFPR license status codes mean
When you look up a sub's Illinois license, IDFPR returns one of several status values. Here is what each means and what action it should trigger before that sub sets foot on your job site.
The license is current and the holder is authorized to practice.
This is the only status that confirms a contractor's license is valid and current. Note the expiration date — even an Active license can be weeks away from lapsing. IDFPR license renewal cycles vary by license type: roofing contractors renew every 2 years, home inspectors every 2 years, architects every 2 years, and professional engineers every 2 years.
The license renewal deadline has passed without action.
Not Renewed is the most common lapsed status in the IDFPR database. The contractor's authorization to practice has expired. Do not engage a sub with a Not Renewed license for regulated work — they need to complete the IDFPR renewal process and return to Active status before resuming licensed activity.
The licensee has placed the license on voluntary inactive status.
An Inactive IDFPR license does not authorize the holder to perform services requiring that license. Contractors sometimes go Inactive between engagements or when winding down. Verify Active status before allowing any licensed work to proceed.
IDFPR has temporarily restricted the license following a disciplinary action.
A Suspended IDFPR license results from disciplinary proceedings — unpaid child support, disciplinary orders, or enforcement actions. Unlike some states that auto-suspend for bond lapses, Illinois IDFPR suspensions are typically the result of a formal action. A Suspended license does not authorize practice. Do not allow a Suspended sub to perform licensed work.
The license has been permanently cancelled.
Revocation and Cancellation are terminal statuses — the license no longer authorizes practice and cannot be reinstated through renewal. Remove this contractor from your approved vendor list immediately. A Terminated status carries the same implication.
Property manager note: Illinois requires Community Association Managers (CAM) to hold an active IDFPR license. If your HOA or building uses a management company, verifying their CAM license status is a routine part of due diligence — particularly at contract renewal. The license is searchable under "COMM ASSOC MGR" in the IDFPR database.
Illinois contractor license requirements by trade
Illinois uses multiple licensing authorities depending on the trade. Use this breakdown to confirm which credentials to verify for each sub you hire.
Illinois is one of relatively few states that requires a statewide roofing contractor license. Any company performing roofing work in Illinois must hold an active IDFPR Roofing Contractor license — regardless of where in the state the work occurs. The license requires a qualifying party and renewal every 2 years. An unlicensed roofing sub in Illinois is performing illegal contracting work, which can expose the GC to liability.
Searchable as "ROOFING CONTRACTOR" in the IDFPR database. TrackMyVendor monitors this daily.
Illinois home inspectors must hold an active IDFPR license under the Illinois Home Inspector License Act. The license requires 60 hours of education and ongoing continuing education for renewal. Property managers, real estate agents, and buyers who hire home inspectors should verify their IDFPR license is Active before engaging them for an inspection.
Searchable as "HOME INSPECTOR" in the IDFPR database.
Architects, Professional Engineers, Structural Engineers, and Design Firms are all licensed through IDFPR. Illinois is notable for having a separate Structural Engineer license distinct from the Professional Engineer license — verify which credential your project actually requires before engaging a design professional. Land Surveyors and Landscape Architects are also IDFPR-licensed.
Searchable as "ARCHITECT," "PROF. ENGINEER," "STRUCTURAL ENGINEER," "DESIGN FIRM," "LAND SURVEYOR BOARD," or "LANDSCAPE ARCHITECT."
Illinois does not issue a statewide license for electricians, plumbers, HVAC technicians, or general contractors. These trades are licensed at the local level. In Chicago, the Department of Buildings licenses electrical contractors, plumbing contractors, and general contractors separately. In the suburbs, requirements vary by municipality — Cook County, DuPage, Lake County, and others each have their own rules. You cannot verify these credentials through IDFPR.
If your sub says they're a licensed electrician or plumber in Illinois, ask for their city or county license — not an IDFPR number. There is no IDFPR electrical or plumbing license to verify.
Locksmiths, locksmith agencies, private alarm contractors, and alarm contractor agencies are licensed through the IDFPR Detective Board. Property managers who hire security contractors or alarm installation companies should verify the contractor holds an active IDFPR alarm contractor or locksmith license. These are trackable through TrackMyVendor under the "DETECTIVE BOARD" license type.

What Illinois GCs and property managers actually track
License verification gets all the attention — but most GCs find their day-to-day compliance headaches come from the other two documents.
| Document | How often it expires | How most GCs track it |
|---|---|---|
| IDFPR License | Every 2 years (most types) | Manually, or not at all |
| Certificate of Insurance (COI) | Annually or per project | By email, when they remember |
| W-9 | Per vendor | By request, often at year-end |
