Authority Industries Coverage Verticals: Trades, Services, and Specialties

The Authority Industries directory organizes its coverage across defined industry verticals — groupings of licensed trades, professional services, and regulated specialties that share common licensing frameworks, oversight bodies, and consumer-protection stakes. Understanding how these verticals are structured helps businesses identify where they fit within the directory and helps consumers locate appropriately credentialed providers. This page defines the vertical model, explains how coverage is organized, and maps the decision logic that determines whether a trade or specialty falls within scope.

Definition and scope

A coverage vertical, as used within the Authority Industries directory, is a named cluster of related occupational categories that are subject to licensing, certification, bonding, or insurance requirements under state or federal law. Verticals are not marketing categories — they track regulatory groupings. A plumbing contractor and a gas-line installer may operate under separate license numbers but belong to the same vertical because both fall under mechanical trades oversight in most state licensing board frameworks.

The directory addresses the full span of US-licensed industries, with particular depth in four broad domains:

Construction and Trades — general contractors, electrical, plumbing, HVAC, roofing, masonry, and specialty subcontractors. Licensing in this domain is governed at the state level, with no single federal license; the US Contractor License Types by Trade reference documents how these vary across jurisdictions.
Professional and Personal Services — cosmetology, childcare, real estate, home inspection, pest control, and similar occupations licensed through state boards of professional licensing or equivalent agencies.
Health and Safety Specialties — environmental remediation, asbestos abatement, lead paint removal, and fire-suppression installation, which carry dual oversight from state agencies and, in some cases, the US Environmental Protection Agency (EPA) or the Occupational Safety and Health Administration (OSHA).
Financial and Legal Services — mortgage brokers, insurance agents, notaries, and contract attorneys whose licensing is regulated through state departments of financial institutions, insurance commissioners, or bar associations.

For a fuller breakdown of which specific categories appear across the network, the Authority Industries Directory Purpose and Scope page outlines the founding selection criteria.

How it works

Each vertical is mapped to the licensing bodies that govern it. When a business is evaluated for inclusion, its claimed trade or specialty is cross-referenced against the applicable state licensing board or regulatory agency to confirm that an active license requirement exists. Trades for which no government-issued credential is required in any US jurisdiction fall outside the directory's scope.

Within each vertical, the directory distinguishes between license types and certification types — a distinction the Industry Certification vs Licensure page covers in detail. Licenses are government-issued authorizations to practice; certifications are typically issued by industry bodies such as the National Electrical Contractors Association (NECA) or the Plumbing-Heating-Cooling Contractors Association (PHCC) and supplement but do not replace a state license.

Bonding and insurance requirements also vary by vertical. Roofing contractors in states like Florida and Texas face higher minimum bond thresholds than general handymen, reflecting the higher risk and dollar value of roofing projects. The Bonded and Insured Requirements by Industry reference provides state-level breakdowns for the highest-volume verticals.

Coverage is national in scope but the directory's depth within each vertical reflects the regulatory complexity of that trade. Construction verticals carry more sub-classifications than, for example, personal services, because state contractor licensing boards typically maintain 12 or more distinct license categories per state.

Common scenarios

A general contractor adding a specialty trade. A licensed general contractor who adds electrical work to their service offering must hold a separate electrical contractor license in most states — the GC license does not transfer. The vertical system captures both credentials under distinct sub-classifications rather than collapsing them into one listing.

A service business operating across state lines. A pest control company licensed in Georgia that expands into Alabama and Tennessee must obtain separate licenses in each state. The National Licensing vs State Licensing page explains why federal preemption rarely applies to trades and service businesses, and the Reciprocal Licensing Across States resource identifies the limited set of trades where reciprocity agreements reduce duplicate testing requirements.

A professional with an industry certification but no state license. A home energy auditor holding a Building Performance Institute (BPI) certification may not hold a state license because not all states license that specialty. Under the directory's framework, unlicensed specialties in states that do not require licensure are flagged as certification-verified rather than license-verified — a meaningful distinction for consumers reviewing credentials.

Decision boundaries

Not every trade or service business qualifies for inclusion. The vertical framework enforces three decision boundaries:

Regulatory presence — the occupation must be subject to a government-issued license, registration, or certification requirement in at least one US state. General laborers, for example, are not included because no state issues a "laborer" license.
Verifiability — the license or credential must be checkable through a public state database or licensing board portal. Trades where the only "credential" is a private membership fall outside scope.
Consumer-protection relevance — the occupation must have a documented pattern of consumer-protection oversight, such as complaint processes through a state board. This criterion excludes purely commercial B2B trades with no public licensing board structure.

Comparing two adjacent categories illustrates this logic: a licensed home inspector (licensed in 31 states as of data from the American Society of Home Inspectors (ASHI)) clears all three thresholds and is included. A property stager — who arranges furniture before a home sale — meets none of the three and is excluded, regardless of any private trade association membership.

Businesses uncertain whether their specialty falls within a covered vertical can consult the Authority Industries Listing Criteria page, which documents the full inclusion ruleset.
