How to Verify a Texas Contractor License Before Hiring

License verification is a foundational step in contractor selection across Texas, with distinct processes depending on the trade category and the licensing authority involved. Texas does not operate a single unified contractor licensing system — responsibility is divided among state agencies, municipal licensing boards, and trade-specific regulatory bodies. Understanding which agency holds authority over a given contractor type determines where verification must occur and what records are accessible.

Definition and scope

Contractor license verification is the process of confirming that a contractor holds a valid, current authorization to perform specific work in a defined jurisdiction. In Texas, this confirmation must occur at the correct level — state, county, or municipal — because licensing authority varies by trade and location.

Texas law, specifically the Texas Occupations Code, mandates state-level licensing for trades including electrical, plumbing, air conditioning and refrigeration, and fire suppression work. The Texas Department of Licensing and Regulation (TDLR) administers licenses for air conditioning contractors, irrigators, and a range of other specialty trades. The Texas State Board of Plumbing Examiners (TSBPE) governs plumbing licensure. Electrical contractors and master electricians are licensed through the Texas Department of Licensing and Regulation under the Electricians program.

Scope coverage and limitations: This page addresses contractor license verification within Texas state jurisdiction. Federal contractor registrations (such as SAM.gov registration for federal projects), out-of-state licenses, and municipal business permits not linked to trade-specific state boards fall outside this page's scope. General contractors performing residential or commercial construction in Texas are not subject to a state-issued general contractor license — that classification is not covered by a statewide credential and does not appear in state license lookup systems. Verification for general contractors relies on other mechanisms described below. For a broader orientation to how the Texas contractor services sector is structured, the Texas contractor regulatory agencies reference outlines the full landscape of oversight bodies.

How it works

License verification operates through official online lookup portals maintained by the relevant licensing authority. The process differs by trade:

1. TDLR License Search — Navigate to the TDLR License Search tool and enter the contractor's name, license number, or business name. Results display license type, status (active, expired, suspended, revoked), expiration date, and associated disciplinary history.
2. TSBPE Licensee Lookup — The Texas State Board of Plumbing Examiners provides a searchable database of licensed plumbers and plumbing contractors. Search by name or license number returns current status and endorsements.
3. Municipal Verification — Cities including Houston, Dallas, San Antonio, and Austin maintain independent licensing registries for trades or for general business authorization. Houston, for example, administers its own Contractor Registration program through the City of Houston's Administration and Regulatory Affairs Department.
4. Insurance and Bond Confirmation — License status alone does not confirm current insurance. Verification of active liability insurance and bonding requires requesting a certificate of insurance directly from the contractor, then confirming the certificate with the named insurer. Texas contractor insurance requirements are detailed separately at Texas contractor insurance requirements.

Expired licenses are a common failure point. A contractor whose license lapsed within the prior 12 months may still appear in search results but with a status of "expired" — that status means the contractor is not currently authorized to perform licensed work. Contracting with an unlicensed or lapsed-license contractor exposes a property owner to significant legal and financial risk, as documented under Texas unlicensed contractor penalties.

Common scenarios

Residential remodel — plumbing subcontractor: A homeowner hiring a general contractor for a bathroom renovation should independently verify the plumbing subcontractor through TSBPE, not solely rely on the general contractor's assurances. The general contractor's own license does not transfer authority to perform licensed plumbing work.

Commercial HVAC installation: A commercial property manager contracting for a rooftop unit installation should verify the HVAC contractor through TDLR's air conditioning contractor license database. The Texas Department of Licensing and Regulation requires that firms performing air conditioning and refrigeration work hold an HVAC Contractor License, distinct from a technician-level EPA 608 certification. More on qualification standards appears at Texas HVAC contractor requirements.

Electrical work — residential vs. commercial contrast: Residential electrical work and commercial electrical work in Texas both require licensure through TDLR, but the license class differs. A Residential Wireman license is valid for single-family and duplex structures; a Journeyman Electrician or Master Electrician license is required for commercial projects. Verifying that the license class matches the project type is as important as verifying that any license exists. Additional classification detail appears at Texas electrical contractor requirements.

Roofing contractors: Texas does not require a state-level roofing contractor license. Verification for roofing work must occur at the municipal level (where applicable) and through confirmation of liability insurance and, where required, surety bonding. The regulatory context is detailed at Texas roofing contractor regulations.

Decision boundaries

The appropriate verification path depends on three factors: trade category, project location, and project type (residential vs. commercial).

When a contractor's license number cannot be found in any state database and the trade category requires state licensure, that absence is dispositive — the contractor is not authorized to perform that work under Texas law. Proceeding with an unlicensed contractor for a state-licensed trade creates liability exposure and may void building permits. Permit requirements that intersect with licensing are covered at Texas contractor permit requirements.

For background screening beyond license status — including criminal history checks relevant to residential contractor hiring — the standards are outlined at Texas contractor background check requirements.
