Is commercial contractor verification different from residential?

Commercial and residential contractor verification overlap on the public-records core but diverge on procurement structure, financial thresholds, and federal compliance.

Residential contractor verification:

- License board check (state). - Secretary of State entity match. - County and federal court records. - OSHA enforcement records. - BBB profile. - Workers' comp via licensing board. - Insurance via direct insurer call. - Reference checks with prior customers. - Permit history via local building department or BuildZoom.

Coverage limits typically: $1M general liability minimum, $5,000-$25,000 contractor bond, workers' comp.

Commercial contractor verification adds:

1. Project-specific bonds. Commercial projects typically require performance bonds (guarantees project completion) and payment bonds (guarantees subs and suppliers get paid). Bond amounts equal contract value. The surety underwrites the contractor's capacity before issuing the bond — meaning the contractor must demonstrate financial strength.

2. Higher insurance limits. $2M-$5M general liability standard for mid-size commercial. $10M-$25M for large commercial. Umbrella policies above primary GL.

3. Project labor agreements (PLA) and union compliance. Commercial union contractors must demonstrate compliance with local PLAs, prevailing wage requirements (Davis-Bacon on federal, state prevailing wage laws), and trade-specific labor agreements.

4. Safety-management system review. Commercial contractors typically maintain ISN, Avetta, Veriforce, or other prequalification accounts. These platforms aggregate insurance, training, OSHA history, and safety-management documentation. Owners require contractors to maintain a passing score before being eligible to bid.

5. Federal contracting compliance (for federal work or federally-funded projects).

- SAM.gov registration and exclusion check. Federally debarred contractors cannot perform federal work. - CPARS (Contractor Performance Assessment Reporting System) ratings for prior federal performance. - DUNS/UEI numbers, NAICS code certification. - Small Business Administration certifications (8(a), HUBZone, WOSB, SDVOSB, etc.) if relevant. - Federal tax lien check (more comprehensive than residential). - Buy American Act and Trade Agreements Act compliance.

6. Financial statements review. Commercial owners often request audited or reviewed financial statements before bid award. Working capital, bonding capacity, debt-to-equity ratios.

7. Project portfolio and case studies. Commercial contractors are evaluated on completed projects of similar size and scope.

8. Insurance certificate for the specific project. Commercial COIs are project-specific, listing the owner as additional insured, with waivers of subrogation. Standard ACORD 25 with proper additional-insured endorsements.

9. Lien waivers integrated into payment process. Commercial payment applications include monthly conditional and unconditional lien waivers from the GC and all subs/suppliers.

10. Default workforce verification. Some commercial owners verify worker eligibility via E-Verify, especially on federal or government-funded work.

Where Groundcheck fits:

Groundcheck (earthmove.io/trust) handles the public-records core for both residential and commercial: state license, Secretary of State, court records, OSHA, BBB, phoenix detection. Pro tier ($99.99/month) adds SAM.gov debarment and federal tax lien coverage.

For commercial procurement above $500,000 contract value, supplement Groundcheck with:

- A commercial prequalification platform (Avetta, ISNetworld, Veriforce, Browz) for ongoing safety and insurance compliance. - Bond capacity verification with the surety. - Financial statements review (in-house finance team or outside CPA). - Owner-controlled insurance program (OCIP) or contractor-controlled (CCIP) for very large projects. - Project-specific bond and insurance certificate review by risk management or legal.

For residential and small commercial under $500,000: Groundcheck Deep Dive + insurer call + reference checks + permit history review is sufficient diligence.

The risk profile difference: residential project failure costs the homeowner up to the contract value (typically $20,000-$200,000). Commercial project failure can cost millions in delay damages, scope-of-work coordination issues, and litigation. The verification depth scales with the dollars at stake.
