Authority Network America: Contractor Verification Framework

Contractor verification in the United States home services and trades sector operates without a single federal licensing standard, producing a fragmented landscape where qualification requirements vary by state, municipality, and trade classification. This page describes how the Authority Network America verification framework structures credential review, license validation, and professional classification across the eight member sites that form this network. The framework applies to licensed trades including plumbing, HVAC, electrical, roofing, pool services, and general contracting — sectors where unverified practitioners represent documented risks to property and public safety. Understanding how verification is scoped and applied is essential for service seekers, industry professionals, and researchers navigating provider selection at scale.

Definition and scope

The Authority Network America contractor verification framework is a structured protocol for confirming that trade professionals listed or referenced across network member sites hold valid state-issued licenses, carry required insurance coverage, and meet the minimum qualification standards established by the relevant licensing authority in their jurisdiction.

Contractor verification is distinct from contractor certification. Certification typically involves third-party testing against a defined competency standard — such as the North American Technician Excellence (NATE) certification for HVAC professionals. Verification, by contrast, confirms that a contractor holds a license issued by a state regulatory body and that the license is currently active and in good standing. Both processes can apply to the same professional, but they draw on different evidence sources and carry different legal weight.

The network's scope covers trades regulated under state contractor licensing boards, building departments, and occupational licensing agencies across all 50 states. Licensing structures differ materially by trade: electrical contractors in 44 states are required to hold a state-issued license (National Electrical Contractors Association, NECA State Licensing Map), while plumbing and HVAC licensing thresholds vary in ways that require trade-specific verification pathways.

The Network Quality Benchmarks page describes the minimum documentation thresholds applied to each trade category within this system.

How it works

Verification within this framework proceeds through four structured stages:

  1. License lookup — The contractor's license number is cross-referenced against the issuing state's public licensing database. Most state contractor boards maintain publicly accessible lookup tools; no data is accepted from the contractor's self-report alone.
  2. Insurance confirmation — General liability coverage and, where required by state law, workers' compensation insurance are confirmed through a certificate of insurance (COI) dated within the current policy period.
  3. Trade classification match — The license type is matched to the scope of work claimed. A licensed general contractor does not automatically satisfy verification requirements for specialty trades such as electrical or plumbing; separate licenses must be confirmed.
  4. Complaint and disciplinary record review — State licensing board complaint histories are reviewed where public records are accessible. Disciplinary actions, license suspensions, and revocations are disqualifying events under network listing standards.

The Network Compliance Requirements page details the documentation formats accepted at each stage and the renewal intervals applied to standing verifications.

Common scenarios

Residential service request — single trade: A homeowner contacts a plumber through the National Plumbing Authority, a network member site that covers plumbing licensing standards, code compliance, and service provider qualification across residential and commercial categories. Verification confirms the plumber holds an active master plumber or journeyman license appropriate to the work scope and jurisdiction.

HVAC replacement — equipment-specific licensing: The National HVAC Authority covers HVAC contractor qualifications, including EPA Section 608 certification requirements for refrigerant handling under 40 CFR Part 82. A technician performing refrigerant work must hold Section 608 certification in addition to any state contractor license — these are verified as distinct credentials.

Electrical panel upgrade — dual license requirement: In states such as California, electrical contractors must hold both a C-10 Electrical contractor license from the Contractors State License Board and demonstrate active workers' compensation coverage. The National Electrical Authority provides trade-specific reference covering electrical licensing structures, NEC compliance frameworks, and jurisdictional variation in permit requirements.

Roof replacement — insurance weight: Roofing is one of the highest-liability residential trades, with average claim values that make insurance verification especially consequential. The National Roof Authority covers roofing contractor classification, material standards, and state-by-state licensing requirements — including the distinction between states with mandatory roofing-specific licenses and those that default to general contractor classification.

Pool construction — specialty licensing: Pool and spa construction falls under specialty contractor classifications in states including Florida, California, and Texas, where separate licenses are required beyond a general contractor credential. The National Pool Authority addresses pool contractor licensing, safety standards, and equipment qualification across these jurisdictions.

The Provider Listing Standards page specifies how verification outcomes are recorded and reflected in member site listings.

Decision boundaries

Not every contractor interaction triggers the same level of verification. The framework applies a tiered review model based on risk classification:

The Authority Designation Explained page describes how trade risk classification is assigned and updated within the network.

The National Contractor Authority functions as the general contracting reference point for the network, covering multi-trade licensing, bonding requirements, and the distinction between general contractor and specialty contractor classifications across states.

Verification status is not permanent. License renewals, insurance lapses, and new disciplinary actions require re-verification at intervals defined in the Network Provider Onboarding documentation. A provider that passes initial verification but subsequently receives a license suspension would be reclassified as unverified pending resolution.
