The 2026 Contractor Background Check Guide

Hiring the wrong contractor is the most expensive mistake a homeowner can make. This guide walks through every public record you should pull before you sign — the DIY route, what it misses, and how Scout does the same investigation in five minutes for $79.

Why a contractor background check matters

The average homeowner loses $10,000–$60,000 to a bad contractor — bounced checks, abandoned jobs, mechanics liens filed by unpaid subs, and uninsured workplace injuries. Almost every one of those losses was preventable from public records the homeowner never thought to check.

A real background check answers four questions: Is this contractor licensed and insured? Has anyone sued them? Are they cited for safety or wage violations? What do their last 50 customers actually say?

The 7 public records to pull on every contractor

  1. State license board. Status, classification, bond, workers' comp, disciplinary actions.
  2. Secretary of State. Entity status, registered agent, principals — confirms the business actually exists under that name.
  3. Court records. CourtListener + county clerk for lawsuits, judgments, bankruptcies, mechanics liens.
  4. OSHA citations. Serious / willful / repeat violations on the business name.
  5. DOL wage-theft judgments. Back-pay orders against the company.
  6. Permit history. Finalized vs open vs failed inspections across the counties they work in.
  7. BBB · Yelp · Google. Read the 1- and 2-star reviews first; those are where pattern complaints live.

The DIY route — free, but slow

You can pull every record above yourself for free. Plan on 60–90 minutes per contractor, plus the learning curve of each state's license-board UI and your county clerk's court search. Honest warning: most homeowners stop after the BBB profile and miss the records that actually predict risk (OSHA, DOL, court).

What Scout does differently

BuildSafe's Scout runs all 13 forensic modules in parallel, normalizes names across DBAs, downgrades anything it can't verify, and synthesizes a Trust Score with citations. Every finding links to the source page so you can verify it yourself.

  • Direct-board adapters for TX, CA, FL, OR, WA — plus nationwide SOS/court/OSHA/DOL coverage.
  • Shovels permit history with failed-inspection flags.
  • Subcontractor network from co-applicant permit data.
  • Sex-offender & felony registry cross-check on principals.
  • Citation-linked Top 5 Findings + plain-English Scout Verdict.

Red flags Scout looks for

  • License status "expired", "suspended", or "no record found".
  • Multiple mechanics liens filed by subcontractors in the past 3 years.
  • OSHA serious or willful citations within the last 5 years.
  • DOL back-pay judgment — a strong predictor of cash-flow problems mid-job.
  • Pattern of failed final inspections across multiple permits.

Pricing — DIY vs Scout

The DIY route is free; Scout is $79 per report. Most homeowners run 1–3 reports before signing. Investors, GCs, and insurance adjusters typically move to Scout Pro at $199/month for unlimited investigations and weekly auto-monitoring, or the BuildSafe API starting at $299/month.

Questions homeowners ask

Contractor background check FAQ

How do I run a background check on a contractor for free?
Start with your state's license-board lookup, your county clerk's court & lien search, the BBB profile, and Google / Yelp reviews. It's free but slow — typically 60–90 minutes per contractor — and you'll still miss OSHA citations, DOL wage-theft judgments, and permit history without paid sources.
What's the most important thing to check before hiring a contractor?
License status with bond and workers' comp on file. An unlicensed or lapsed contractor invalidates most homeowner insurance claims and removes your ability to file a complaint with the state board if the job goes wrong.
Are online contractor background checks legal?
Yes when they use public records. BuildSafe only aggregates publicly available data and is not an FCRA consumer reporting agency — meaning reports cannot be used for credit, employment, or tenancy decisions, but they're perfect for hiring a contractor on your own home.
How much should I budget for a contractor background check?
DIY is free but takes 60–90 minutes and misses key sources. A full BuildSafe forensic report is $79. For investors or GCs running multiple checks a month, Scout Pro at $199/mo or the BuildSafe API at $299/mo is cheaper per report.
How do I check OSHA violations for a contractor?
OSHA's Establishment Search tool is public but indexed by business name only — variations and DBAs miss. BuildSafe normalizes the name, pulls every matching inspection, and surfaces serious / willful / repeat citations with dates and penalty amounts.
