Does Missouri require contractors to be licensed in St. Louis?

Missouri does not require a statewide general contractor license. Anyone can legally call themselves a general contractor in Missouri without a state credential. St. Louis city and St. Louis County each have their own local contractor registration and permit requirements. Specialty trades (electrical, plumbing, HVAC) are licensed statewide through the Missouri Division of Professional Registration at pr.mo.gov.

How do I verify a contractor in St. Louis?

For trade contractors, verify the Missouri state license at pr.mo.gov. For general contractors, contact St. Louis County's Department of Public Works or the City of St. Louis Building Division depending on your location. Check the Missouri AG's complaint database at ago.mo.gov. Also search the BBB's St. Louis database and call the insurance carrier directly to verify the policy is current.

What contractor scams are common in St. Louis?

St. Louis has seen documented cases of contractors collecting deposits from multiple homeowners and failing to perform work. Missouri AG Andrew Bailey obtained a default judgment against a St. Louis County general contractor (A-1 Construction, John G. Adams) for defrauding six homeowners. Missouri contractor Brandon Ward was convicted of felony charges for collecting $61,650 in upfront deposits and abandoning projects. The deposit-and-abandon pattern is most common.

What is the Illinois side of the St. Louis market?

The greater St. Louis area spans Missouri and Illinois, with cities like Belleville, O'Fallon, Edwardsville, and Collinsville on the Illinois side. Illinois has its own licensing rules — most importantly, Illinois does not require a state GC license either, but roofing contractors must be licensed through IDFPR. If your project is on the Illinois side of the metro, Illinois law governs your contract, including the requirement for written contracts on jobs over $1,000.

How do I report a contractor scam in St. Louis?

For Missouri addresses: File with the Missouri AG at ago.mo.gov or call 800-392-8222. For Illinois addresses: File with the Illinois AG at illinoisattorneygeneral.gov or 1-800-386-5438. Also file with the BBB serving Eastern Missouri.

How to Find a Good Contractor in St. Louis: Missouri Licensing, Fraud Cases, and Verified Pros

St. Louis homeowners face a combination of risks: Missouri's no-GC-license environment, a documented history of local contractor fraud, and the cross-state complexity of the metro spanning Missouri and Illinois. Getting the verification steps right before signing anything is especially important here.

Missouri's Contractor Licensing Gap — What St. Louis Homeowners Need to Know

Missouri does not require a statewide general contractor license. This is not unusual for the Midwest — Ohio and Indiana share this gap — but it means every homeowner must rely on local verification rather than a statewide credential database.

What is licensed at the state level:

Electrical contractors: Missouri Division of Professional Registration, pr.mo.gov
Plumbing contractors: pr.mo.gov
HVAC contractors: pr.mo.gov

What requires local verification:

General contractors in St. Louis County: St. Louis County Department of Public Works
General contractors in St. Louis city: City of St. Louis Building Division
St. Charles County, Jefferson County, and other surrounding counties: Each has its own building department

Illinois side of the metro: If your property is in Belleville, O'Fallon, Edwardsville, or other Illinois communities, Illinois rules govern. Illinois also has no state GC license requirement (only roofing is state-licensed via IDFPR). The Illinois Home Repair and Remodeling Act requires a written contract for any job over $1,000.

Documented St. Louis-Area Contractor Fraud Cases

St. Louis County — A-1 Construction General Contractor (John G. Adams): Missouri AG Andrew Bailey obtained a default judgment against Adams and his company after he falsely promised home renovation and repair services to six Missouri homeowners, collected deposits, and did not perform the contracted work. The default judgment was entered because Adams did not respond to the lawsuit — a pattern common when contractors know they cannot defend the claims. (Missouri Attorney General)

Statewide — Brandon Ward / Insight Contractors (felony conviction): Ward pleaded guilty to felony Deceptive Business Practice and Stealing charges after collecting $61,650 in upfront payments from homeowners for projects that were never completed. Sentenced to probation with full restitution ordered in October 2025. This case illustrates how Missouri's AG uses consumer protection statutes to pursue criminal charges — not just civil judgments — against repeat offenders. (Hoodline, October 2025)

St. Louis Storm Season and Contractor Risk

St. Louis sits in a corridor that experiences significant spring storm activity — hail, high winds, and tornadoes. The Midwest storm-chaser problem (documented extensively in Illinois, Ohio, and Indiana) is equally present in St. Louis. After large events, out-of-state contractors specifically enter the St. Louis market targeting both the Missouri and Illinois sides.

After any storm: Do not sign a contract before your insurance company has completed its own damage assessment. Never let a door-to-door contractor convince you that signing their contract first is required to "lock in" insurance coverage — it is not. Your insurer's adjuster visit is the starting point, not the contractor's pitch.

Missouri Contract Law — What You're Entitled To

Missouri requires a written contract for home improvement projects over $500. For larger projects, a detailed, itemized contract is not just good practice — it is your primary legal protection.

Every St. Louis contractor contract should include:

Full project scope with specific materials (brand, grade, quantity)
Start date and projected completion date
Payment schedule tied to completion milestones
Change order process requiring written approval before work proceeds
Contractor's business license number, insurance carrier and policy number
Lien waiver clause

Missouri's mechanics lien law allows subcontractors and suppliers to lien your property if the GC doesn't pay them — even if you paid the GC. Require signed lien waivers at every payment milestone.

What to Ask Before Hiring in St. Louis

Are you registered with St. Louis County/City and in good standing with the building department?
