Authority Network America: Full Member Directory

Authority Network America functions as the central hub for a structured network of trade- and service-sector reference properties, each covering a distinct vertical within the U.S. home services and contractor landscape. This directory documents all 8 member sites, their subject scope, and how they interrelate within the broader network architecture. Professionals, researchers, and service seekers can use this reference to identify which member property governs a given trade category and how the network's credentialing and quality standards apply across verticals. The member directory is the authoritative index for all current network affiliations.

Definition and scope

Authority Network America (ANA) is a nationally scoped reference network comprising 8 member sites organized by trade vertical. Each member site operates as an independent reference authority for its designated sector — covering licensing frameworks, regulatory bodies, professional qualifications, and service delivery standards — while drawing on shared network-level policies documented in the Authority Network America standards reference.

The network does not operate as a contractor marketplace or lead-generation service. Its function is informational and structural: establishing publicly accessible, sector-specific reference infrastructure for the U.S. trades and home services industry. The Authority Network America provider framework governs how providers are represented across member properties, and the network membership criteria define the qualifications a site must meet to carry the ANA designation.

Scope spans the following trade and service verticals:

Plumbing systems and licensed plumbing contractors
HVAC (heating, ventilation, and air conditioning) systems and technicians
Electrical systems, licensed electricians, and electrical contractors
General contracting and specialty contractor classifications
Residential and commercial roofing
Swimming pool construction, service, and compliance
Cross-vertical network reference (authoritynetwork.org)
National authority standards and policy reference (nationalauthority.org)

How it works

Each of the 8 member sites covers a single vertical with depth sufficient for licensing research, regulatory navigation, and contractor qualification assessment. The hub-and-spoke architecture means ANA maintains network-level policies — including the network quality benchmarks and the network compliance requirements — while each member site applies those standards within its own trade context.

Member site breakdown:

National Plumbing Authority covers licensing requirements, code jurisdiction maps, and professional classification standards for plumbers across all 50 states. It is the primary reference for understanding the distinction between journeyman and master plumber licensing tiers, which vary significantly by state board. Additional context on this vertical appears in the plumbing, HVAC, and electrical overview.

National HVAC Authority addresses EPA Section 608 certification requirements, NATE credentialing, state-level contractor licensing, and equipment classification standards for heating, cooling, and ventilation professionals. The site covers both residential and light-commercial HVAC contexts.

National Electrical Authority documents the National Electrical Code (NEC) adoption status by jurisdiction, state licensing structures for electricians, and the tiered classification system distinguishing apprentice, journeyman, and master electrician credentials. NEC editions adopted at the state level have diverged by as many as 3 code cycles in some jurisdictions (NFPA NEC Adoption Map).

National Contractor Authority provides reference infrastructure for general contractors and specialty trades not covered under plumbing, HVAC, or electrical verticals. It addresses bonding requirements, general liability insurance thresholds, and the classification differences between general, residential, and commercial contractor licenses. The contractor verification framework draws directly on this member's scope.

National Roof Authority covers roofing contractor licensing (which exists in fewer than 25 states as a standalone credential), manufacturer certification programs, and the material-specific standards governing asphalt shingle, metal, and low-slope roofing systems. The roofing and pool exterior overview provides cross-vertical context.

National Pool Authority addresses pool contractor licensing, the Association of Pool & Spa Professionals (APSP) standards, and state-specific requirements for pool construction permits and water safety compliance.

Authority Network Org serves as a cross-vertical reference point addressing how the network's shared infrastructure — quality benchmarks, data integrity policies, and referral protocols — functions across trade categories.

National Authority Org operates as the broadest-scope member, addressing national-level authority standards, professional designation frameworks, and the policy architecture that underpins the network's reference credibility.

Common scenarios

Scenario 1 — Contractor licensing research. A property developer operating across multiple states needs to verify that subcontractors hold valid trade licenses in each jurisdiction. Depending on the trade, the relevant member site provides jurisdiction-specific licensing structure: plumbing licensing through National Plumbing Authority, electrical through National Electrical Authority, and general contractor classification through National Contractor Authority. The home services vertical summary maps trade categories to their relevant member properties.

Scenario 2 — Credential tier comparison. A researcher distinguishing between EPA 608 certification (a federal requirement for HVAC refrigerant handling) and state-level HVAC contractor licensing finds that these are parallel, non-substitutable credentials — one is federally mandated by the U.S. Environmental Protection Agency, the other is administered at the state level. National HVAC Authority documents both layers.

Scenario 3 — Network provider onboarding. A trade association seeking to understand how member sites evaluate and list providers consults the network provider onboarding and provider listing standards pages. These reference the quality and compliance requirements enforced uniformly across all 8 member properties.

Decision boundaries

The ANA network is structured around vertical exclusivity: each trade category maps to exactly one primary member site. Overlap scenarios — such as a contractor who holds both plumbing and HVAC licenses — are addressed at the cross-vertical level through the cross-network referral protocol rather than by duplicating content across member properties.

Reference site vs. licensing authority: ANA member sites document licensing frameworks; they do not issue licenses, certifications, or professional designations. Licensing authority rests with state boards, the EPA (for EPA 608), and trade-specific bodies such as NATE and APSP. The authority designation explained page clarifies this distinction in detail.

Network scope vs. geographic scope: All 8 member sites cover U.S.-national scope by default, with state-level detail where licensing structures vary by jurisdiction. The network geographic coverage page documents which regulatory variations are tracked at the state level across each vertical.
