Authority Industries Listings
The home services industry in the United States spans hundreds of licensed trades, regulated professions, and consumer-facing service categories — from residential plumbing and electrical work to roofing, landscaping, and pest control. This page provides a structured reference to the major industry categories operating under authority-network standards, explaining how listings are organized, what qualifies a provider for inclusion, and how homeowners can use category-level data to make informed decisions. Understanding the scope and structure of industry listings helps both service professionals and property owners navigate licensing requirements, insurance mandates, and contractor verification processes with greater precision.
Definition and scope
An authority industries listing, in the context of a national home services reference network, is a structured directory entry that identifies and categorizes licensed home service providers by trade, credential type, and geographic service area. These listings are not advertising placements — they are reference-grade classifications built around verifiable professional standards, including state-issued licenses, bond requirements, and trade-specific certifications.
The scope of coverage extends across the full residential services spectrum. The home services industry categories page breaks this into 12 primary trade groupings, ranging from skilled mechanical trades (HVAC, plumbing, electrical) to specialty services (pest control, home cleaning, home remodeling). Each grouping operates under distinct regulatory frameworks: electrical contractors in most states must carry a master electrician license, while landscaping professionals face licensing requirements in fewer than half of all U.S. states, according to the National Home Services Regulatory Landscape.
Within this network, listings are scoped nationally but resolved locally. A provider appearing under a roofing category listing, for example, will be associated with specific state licensing credentials applicable to their operating jurisdiction — not a generalized national credential.
How it works
Authority industry listings are organized through a three-layer classification structure:
- Trade category — The primary service type (e.g., electrical, HVAC, plumbing, roofing, pest control)
- Licensing tier — Whether the provider holds a journeyman, master, or contractor-grade license as defined by the applicable state licensing board
- Credential verification status — Whether the provider's bonding, liability insurance, and active license have been cross-referenced against state licensing board records
The how to verify a home services contractor reference outlines the specific data points used in this process, including license number formats by state, insurance certificate standards (typically $1,000,000 per occurrence in general liability for most residential trades), and bond thresholds.
Listings that appear in trade-specific authority references — such as the plumbing services authority reference or the electrical services authority reference — carry additional trade-specific metadata, including relevant certifications (e.g., EPA 608 for refrigerant-handling HVAC technicians) and applicable code compliance standards.
The distinction between this model and a general contractor marketplace is addressed in detail at home services network vs franchise vs marketplace. The core operational difference: marketplace platforms aggregate self-reported provider data, while authority listings require third-party verifiable credentials as a baseline entry condition.
Common scenarios
Scenario 1 — Homeowner researching before hiring
A homeowner seeking a licensed roofer in a state with mandatory contractor licensing uses trade category listings to identify credential requirements before contacting any provider. The roofing services authority reference documents that 46 states require some form of contractor registration or licensing for roofing work, giving the homeowner a baseline expectation for verification.
Scenario 2 — Service professional seeking classification
A pest control operator with a state-issued pesticide applicator license seeks to understand how their credentials map to listing standards. The certifications for home service professionals reference clarifies that EPA-registered pesticide licensing, administered at the state level under the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA), is the minimum federal baseline — states may layer additional requirements above this threshold.
Scenario 3 — Dispute or complaint context
When a service interaction leads to a dispute, the listings structure provides a reference point for which regulatory body holds jurisdiction. Electrical contractor complaints, for instance, route to state electrical licensing boards, while general contractor issues may involve the contractor licensing division of a state's department of consumer affairs. The home services complaint and dispute resolution page maps these jurisdictional boundaries by trade type.
Decision boundaries
Not all home service providers are eligible for inclusion across all listing categories, and the boundaries follow three primary criteria:
Licensed vs. unlicensed trades — Trades requiring a state-issued license (electrical, plumbing, HVAC in most states) are separated from trades where licensing is optional or varies by municipality. The home services contractor licensing by trade reference documents 28 trade types and their licensing status across all 50 states.
Bonded and insured vs. unverified — Providers without documented general liability insurance and surety bonding are excluded from primary listings and flagged in the bonding and insurance requirements home services reference. Minimum bond thresholds vary by trade and state, with figures ranging from $5,000 for basic handyman registrations to $500,000 for general contractors in states with more stringent requirements.
Authority network model vs. independent contractors — The authority industries vs independent contractors page defines the operational distinction. Independent contractors operating outside a licensed business entity face different insurance obligations and are classified separately within listing data, particularly in states where sole-proprietor contractor licenses carry different scope limitations than entity-based contractor licenses.
Providers operating in regulated trades without current, active licensure are not listed under credential-verified categories, regardless of experience or customer reviews — credential currency is evaluated against the issuing state board's real-time license status database as the authoritative source.
