How to File Contractor Fraud Complaints

Last reviewed: April 28, 2026

Quick Summary

Contractor and home improvement fraud cost Americans over $3.4 billion in 2025. Common schemes include unlicensed contractors, advance payment scams, shoddy workmanship, abandoned projects, and deceptive estimates. Attorney Generals and state licensing boards have authority to investigate contractors, revoke licenses, and help consumers recover losses through restitution orders.

Most Common Scam: Contractor demands large upfront payment (50-100%), then abandons job or does substandard work. Never pay more than 10-20% upfront. Most states limit deposit amounts by law.

Common Contractor Fraud & Violations

Unlicensed Contractors

Most serious violation

  • Operating without required state/local license
  • Expired license
  • Using someone else's license number
  • Suspended or revoked license
  • No workers' compensation insurance
  • No liability insurance

Consequences: In most states, unlicensed contractors can't sue to collect payment and homeowner may void contract. Criminal charges possible.

2025 stat: 38% of home improvement complaints involve unlicensed contractors

Payment Scams

  • Demanding large upfront deposits (50-100% of job)
  • Taking deposit then never starting work
  • Abandoning job after receiving payment
  • Demanding progress payments exceeding work completed
  • Surprise charges not in contract
  • Billing for materials never purchased
  • Pressure to pay in cash only (no paper trail)

Know: Most states limit initial deposit to 10-33% of contract price or $1,000, whichever is less

Contract Violations

  • No written contract provided
  • Starting work before contract signed
  • Contract missing required information (license number, start date, payment schedule)
  • Not providing required notices (3-day right to cancel)
  • Refusing to provide lien release
  • Not honoring warranty promises

Poor Workmanship

  • Work not meeting building codes
  • Failure to get required permits
  • Using inferior materials than specified
  • Incomplete work
  • Defective work requiring correction
  • Creating safety hazards
  • Refusing to fix problems under warranty

Storm Chasers

After natural disasters

  • Door-to-door solicitation after storm
  • High-pressure sales tactics
  • Offering to waive insurance deductible (insurance fraud)
  • No local address or phone
  • Demanding cash payment immediately
  • Disappearing after deposit

Post-disaster rule: Never hire contractor who solicits door-to-door. Always research thoroughly.

Deceptive Practices

  • False claims about credentials or experience
  • Fake references or reviews
  • Bait-and-switch (low estimate, then excessive change orders)
  • Creating false sense of urgency
  • Claiming "limited time" special pricing
  • Misrepresenting scope or necessity of work

Evidence You Need to File Complaint

For guidance on how to present this evidence in writing — structure, exhibits, and tone — see how to write an effective AG complaint.

Essential Documentation Checklist

  • Written contract:
    • Original signed contract
    • All amendments or change orders

  • Communications:
    • All emails with contractor
    • Text messages
    • Letters
    • Notes from phone conversations (date, time, what was discussed)
    • Voicemails (save or transcribe)
  • Photographic evidence:
    • Before photos
    • During construction photos

How to Verify Contractor License

Why License Verification is Critical

  • Confirms contractor is legally authorized to work
  • Verifies insurance coverage
  • Shows complaint history
  • Confirms license is current and not suspended
  • Protects your legal rights (many states allow voiding contracts with unlicensed contractors)

Do this BEFORE hiring, not after problems occur.

State Contractor Licensing Boards

Each state has contractor licensing authority. Common names:

  • State Contractors Board
  • Department of Consumer Affairs - Contractors License Board
  • Board of Contractors
  • Department of Professional Regulation

To find yours: Search "[Your State] contractor license verification" or check your state AG website

What to Check

  • License status: Active, current, not expired
  • License type: Matches work being done (e.g., general contractor, electrical, plumbing)
  • Complaint history: Past complaints or disciplinary actions
  • Insurance: Liability and workers' comp current
  • Bond: Contractor bond in place (required in most states)
  • Business entity: Registered business name matches

Red Flags When Checking License

  • Contractor won't provide license number
  • License doesn't exist or is expired
  • License belongs to different person/company
  • Multiple complaints or disciplinary actions
  • License suspended or under investigation
  • No insurance listed
  • Business name doesn't match license

If you find red flags, don't hire. Report to licensing board.

Common Contractor Fraud Patterns

The patterns below describe how contractor disputes most often play out in state Attorney General contractor-fraud cases and licensing-board investigations.

The post-storm door-to-door roofing scam

After a hailstorm or hurricane, an unfamiliar contractor knocks on doors and offers a discounted roof replacement using "leftover materials from a neighbor's job." A large deposit is demanded up front, no written contract is provided, and work begins without a permit. The job fails inspection, the contractor disappears, and the license number on any paperwork turns out to be fake or recycled. Homeowners then pay a second contractor to redo the work and may pursue restitution through a state contractor recovery fund.

Lesson: verify the license with the state board before signing or paying any deposit, and put everything in a written contract that includes permit responsibilities and a clear payment schedule.

The remodel abandonment

A licensed contractor signs a contract for a kitchen, bathroom, or addition project and asks for a heavy upfront payment — sometimes 50–70% — to "cover materials." Demolition begins, but the contractor is rarely on site, no materials appear, and after a few weeks they stop returning calls. Licensing-board investigations often reveal the same contractor has taken deposits from many homeowners. Remedies include filing with the licensing board, the state contractor recovery fund (where one exists), and small claims court for amounts above any fund cap.

Lesson: never pay more than industry-standard progress payments tied to completed milestones. Many states cap legal upfront deposits.

Substandard work without permits

A contractor quotes a major repair, completes the visible portion, and collects payment, but cuts corners on materials, skips required permits, and leaves work that does not meet building code. Problems surface months later, and an independent inspection confirms the work is inadequate or unsafe. Homeowners file a licensing-board complaint, often supported by the inspection report, and pursue restitution through mediation, small claims, or AG enforcement when the contractor refuses to remediate.

Lesson: require permits in writing as part of the contract, and reserve final payment until the work has passed any required inspection.
