How to Run a Background Check: A DIY Guide to Public Records Research

Whether you are preparing to hire a local contractor, verifying a potential business partner, or trying to understand someone’s history for personal safety, background checks are a powerful investigative tool. While standard “people search” sites make bold claims, running a true, reliable background check requires a methodical search of actual public records.

Here is a step-by-step DIY guide to conducting thorough background research using open-source intelligence (OSINT) and local public records.

The DIY Background Research Process

  1. Search County Court Portals: The majority of criminal records, civil lawsuits, traffic infractions, and evictions are filed at the county level. Visit the official court clerk portal for the counties where the subject has lived. Most counties provide free search options for civil and criminal dockets.
  2. Verify Professional Credentials and Business Status: If you are checking a business or a contractor, search your state’s Secretary of State database to confirm their business registration is active. Always cross-reference their license status with state licensing boards (e.g., medical boards, real estate commissions, or contractor registry sites).
  3. Search Local Real Estate and Property Tax Assessor Portals: Locate the county tax assessor website where the target currently resides. Search their name to verify property ownership, property value, and purchase dates. This is a highly reliable way to confirm an address and financial footprint.
  4. Leverage Advanced Social Media and Digital Sweeps: Don’t rely solely on what a person chooses to show on their main profile page. Use search engine commands (e.g., “First Last Name” site:linkedin.com or “First Last Name” site:facebook.com) to trace employment history, past locations, and potential red flags.

The Legal Limits of DIY Research: The FCRA Wall

If you are running a background check for employment, tenant screening, or credit evaluation, you cannot use public search engines or standard DIY methods. These searches fall strictly under the Fair Credit Reporting Act (FCRA).

By law, you must obtain written consent from the applicant and utilize an FCRA-compliant screening process. Performing these searches informally for business decisions can expose you or your business to massive legal and financial liabilities.

Comparing DIY Research vs. Professional Background Checks

Criteria

DIY / Public Search Portals

Professional Private Investigator

Data Accuracy

High error rate; often mixes records of different people with similar names.

Manually verified by a licensed professional using full identifier data.

Comprehensive Scope

Limited to public digital indices and county systems with online search portals.

Deep-dive access including county, state, federal, and off-grid physical court archives.

Compliance & Legality

Non-compliant for FCRA decisions (tenant screening, employment, credit).

Compliant reports, legally sound methods, and court-admissible evidence.

Record Verification

Relies on instant algorithmic scraping (no manual double-checks).

Direct verification of dispositions, arrests, and dates of birth.

Why Professional Background Checks Make the Difference

Instant internet websites frequently miss critical, recent records—such as pending charges, active warrants, or cases that have changed jurisdictions. Furthermore, they are unable to access the restricted networks used by courts, credit bureaus, and state motor vehicle departments.
