Definition
A contractor is any person or entity that enters into a contract — most broadly, one of the parties to a binding agreement. In practical legal usage, however, the term carries a narrower meaning: a person or company that agrees to perform work or supply goods on a relatively large scale, for a fixed price or defined compensation, either for a public body, a corporation, or a private party.
Legal usage recognizes at least two distinct senses:
1. General sense: Any contracting party. A contractor, strictly, is anyone who makes a contract. This usage appears in older treatises and statutory definitions and is broad enough to encompass both sides of any agreement.
2. Specialized sense: A person engaged to perform construction, infrastructure, service, or supply work under a discrete contract, typically for a defined scope, price, and timeline. This is the dominant modern usage in construction law, public procurement, government contracting, and labor law. Sub-specialties include general contractors (responsible for overall project completion), subcontractors (engaged by the general contractor for specific portions of the work), and specialty contractors (licensed for particular trades such as electrical, plumbing, or mechanical work).
The legal significance of the term depends heavily on context. In employment law, "contractor" (usually "independent contractor") defines a worker classification carrying distinct tax, benefits, and liability consequences. In public procurement, "contractor" defines who bears contractual obligations to a government entity. In construction law, the term anchors allocation of risk, indemnity, and lien rights.

Common Language
Modern common usage (Wiktionary): A person or company that builds or improves structures; performs specific construction trades; maintains facilities; or is hired for a defined job under a business contract rather than as a permanent employee.
Historical common usage (Webster's 1913): One who contracts; one of the parties to a bargain; one who covenants to do anything for another; specifically, one who contracts to perform work on a rather large scale, at a certain price or rate, as in building houses or making a railroad.
The common usage and legal usage largely overlap for the construction sense, but the common meaning has narrowed — ordinary speakers today think primarily of construction and building trades. The legal term is simultaneously broader (any contracting party) and more technically differentiated, particularly around the independent contractor classification, which has no real counterpart in everyday speech but carries significant legal consequences in tax, employment, and benefits law.

Common Confusion
CONTRACTOR vs. EMPLOYEE: The distinction between a contractor (particularly an independent contractor) and an employee is one of the most litigated classification questions in employment and tax law. The relationship may look identical from the outside — one party performs work for another in exchange for compensation — but the legal consequences diverge sharply on liability, benefits entitlement, tax withholding, workers' compensation, and wage-and-hour protections. Misclassification of employees as independent contractors is a major enforcement focus at both federal and state levels.
CONTRACTOR vs. SUBCONTRACTOR: A contractor holds a direct agreement with the project owner or principal. A subcontractor holds an agreement with the contractor, not the owner, and generally has no direct privity with the owner unless established separately. The distinction matters for lien rights, bond claims, and direct liability.

Recognized Forms
/SUBTYPES
General Contractor: Holds the prime contract with the owner; bears overall responsibility for project completion, coordination of subcontractors, and delivery of the finished work.
Subcontractor: Engaged by the general contractor to perform a defined portion of the work. Derives rights and obligations primarily from the subcontract, not from the prime contract, though the prime contract terms are frequently incorporated by reference.
Independent Contractor: A worker or entity engaged to produce a result but not subject to the engaging party's control over the manner and means of performance. The classification carries distinct tax, benefits, and employment law consequences and is determined by multi-factor tests that vary by jurisdiction and legal context.
Government Contractor: A private party contracted to supply goods, services, or construction to a federal, state, or local government entity. Subject to procurement regulations, compliance obligations, and, in many contexts, constitutional constraints that do not apply to purely private contracting.
Prime Contractor: Synonymous with general contractor in most usage; the party holding direct contractual privity with the project owner or government agency.

Why It Matters in Research
The word "contractor" is a research trap precisely because it is used in multiple legal fields with overlapping but distinct meanings. A researcher must identify context before assuming which body of law applies.
In construction law sources, "contractor" presumptively means the general or prime contractor, and the analysis concerns lien rights, bonding requirements, indemnity chains, and scope-of-work disputes. In employment and tax law sources, the operative concept is "independent contractor" as a classification, and the question is whether the classification is valid under the applicable test — which changes depending on whether the issue is FLSA coverage, IRS tax treatment, state wage-and-hour law, or workers' compensation eligibility. These tests are not uniform and have diverged significantly.
Historical sources — Bouvier's, Black's, Anderson's — use "contractor" in the general sense (any contracting party) or the construction/procurement sense interchangeably. Modern legal research will almost always involve the specialized sense. Be alert to nineteenth-century cases and treatises that use "contractor" where modern law would use "obligor," "promisor," or "vendor."
The independent contractor classification has evolved substantially since the mid-twentieth century. Early sources have little on this; the modern doctrinal framework developed primarily through labor and tax regulation. Research on worker classification should not rely primarily on treatise definitions from Bouvier's or Anderson's — those sources predate the framework.
Jurisdictional variation is acute in the independent contractor context. California's ABC test, adopted by statute, is significantly more restrictive than the federal common law control test or the economic realities test used under the FLSA. Research that is not jurisdiction-specific in this area will mislead.
Public contracting adds another layer. Government contractors face regulatory requirements — compliance with procurement statutes, prevailing wage laws, anti-kickback provisions, and in some cases constitutional due process constraints — that have no analog in private contracting. Historical sources covering public works contracts may reflect superseded procurement frameworks.

Historical Dictionary Support
The historical dictionaries agree on the dual meaning — general (any contracting party) and specialized (large-scale work or supply for a fixed price) — and treat both as settled. Black's (both editions) and Bouvier's each acknowledge that while "contractor" is strictly applicable to any contracting party, common usage reserves it for those undertaking work or goods on a large scale. Bouvier's is particularly useful for pointing toward independent contractor liability, explicitly cross-referencing that entry for third-party negligence analysis — an early signal that contractor classification was already a recognized legal problem by the nineteenth century.
Anderson's entry, as captured here, pivots quickly to contract validity doctrines (fraud, illegality, public policy) rather than defining "contractor" as a status, which reflects Anderson's tendency toward doctrinal synthesis over definitional precision. That entry is less useful for understanding who a contractor is and more useful for understanding when a contractor's agreement may be unenforceable.
None of the historical sources address the independent contractor/employee distinction in its modern form. That framework belongs to twentieth- and twenty-first-century statutory and regulatory law. Researchers relying on Bouvier's or Black's alone for worker classification analysis will find the definitions unhelpfully thin.

Jurisdictional Note
Worker classification tests for independent contractors vary significantly across jurisdictions. The IRS applies a multi-factor control test for federal tax purposes; the FLSA uses an economic realities test for wage-and-hour coverage; and many states have adopted their own standards, with California's strict ABC test representing the most employer-restrictive approach currently in force. A determination that a worker is an independent contractor under one standard does not ensure the same result under others.
