A general contractor is the person or company that takes a set of architectural plans and turns them into a finished building. They sign the primary contract with the property owner, hire and coordinate the subcontractors who perform specialty work, pull permits, manage the budget, and keep the schedule on track. If you’re asking what a general contractor does, the short answer is that they are the single point of accountability for a construction project — the one party legally responsible for getting the job built correctly, safely, and within the agreed scope.
Running the Project Day to Day
Most of a general contractor’s work is coordination rather than construction. Before anyone picks up a tool, the contractor secures building permits from the local building department and confirms the project complies with zoning and safety codes. Starting without the right permits risks shutdowns and daily fines.
Once work begins, the contractor runs the site itself. That means installing security fencing, arranging temporary water and power, scheduling waste removal, and calling in inspections at each phase of construction. The real skill is sequencing the trades. Concrete has to cure before framing starts. Framing has to pass inspection before electrical rough-in. Get the order wrong and the delays cascade: every subcontractor’s schedule slips, labor costs rise, and the completion date keeps moving.
Change orders are the other constant. A change order is a formal written amendment to the original contract when the scope, cost, or timeline shifts. A homeowner who decides mid-project to move a wall or upgrade finishes triggers one. The contractor documents the revised work, calculates the cost impact, and gets written approval before proceeding. Verbal “go aheads” with no paper trail are where disputes are born.
Managing Subcontractors and the Payment Chain
In the legal structure of a construction project, the general contractor sits between the property owner and every specialty trade. The owner signs one contract, with the general. The general then signs separate agreements with plumbers, electricians, roofers, concrete crews, and whoever else the job requires. Communication and money both flow through the general contractor.
That payment chain matters more than it looks. The owner pays the general, and the general distributes funds to subcontractors as work is completed. If the general collects payment but fails to pay a subcontractor, that subcontractor can file a mechanic’s lien against the property itself. A mechanic’s lien is a legal claim that attaches to the real estate to secure payment for labor or materials used to improve it. The lien comes from state law, not from any contract with the owner, so the owner’s property can be encumbered even after the owner has already paid the general in full.1Legal Information Institute – Cornell Law School. Mechanic’s Lien
Lien waivers guard against this double-payment risk. These are documents signed by subcontractors confirming they have been paid for specific work and giving up their right to file a lien for that amount. Conditional waivers only take effect once the payment actually clears the bank, which makes them safer for whoever signs. Owners working with a reputable general contractor should expect lien waivers from every subcontractor at each payment milestone, not just at the end.
Filing deadlines for mechanic’s liens vary by state. The window typically runs from three months to one year after work is completed, and many states also require subcontractors to send a preliminary notice near the start of a project to preserve their lien rights at all.
Licensing, Bonds, and Insurance
Most states require general contractors to hold a license before they can legally bid on or perform construction work. About a third of states handle licensing at the city or county level instead of through a statewide board. The specifics differ, but the common elements line up: verified field experience, passing scores on trade and business law exams, proof of insurance, and a surety bond.
States that license contractors generally want applicants to show several years of hands-on experience, often two to five years within the last decade, sometimes with a mix of formal education and field work. Examinations cover both trade knowledge and the business side — safety regulations, labor law, and contract management. A fingerprint-based background check is standard.
A surety bond protects consumers if the contractor violates a contract. Bond amounts range from as low as $1,000 for small residential work to $2,000,000 for large commercial licenses. The bond is not insurance for the contractor; it is a guarantee that money is available to compensate an owner if something goes wrong.
On top of the bond, contractors carry at least two kinds of insurance. General liability covers injuries to third parties and damage to others’ property caused by the contractor’s work. Workers’ compensation covers the contractor’s own employees if they are injured on the job and is required in nearly every state. Some owners also require builder’s risk insurance, which covers damage to the structure itself during construction from events like fire, theft, or storms. Builder’s risk is first-party coverage protecting the building under construction; general liability is third-party coverage protecting everyone else.
Responsibility for Jobsite Safety
General contractors carry a level of safety responsibility that surprises people outside the industry. Under federal OSHA regulations, the prime contractor on a construction project bears overall responsibility for safety compliance across the entire site, including work performed by subcontractors.2Occupational Safety and Health Administration. 29 CFR 1926.16 – Rules of Construction The regulation is explicit: subcontracting out a portion of the work does not relieve the prime contractor of responsibility for that portion. Prime and sub share joint responsibility.
OSHA’s multi-employer worksite policy goes further by classifying the general contractor as a “controlling employer” — an employer with supervisory authority over the worksite and the power to require others to correct violations. A controlling employer must exercise reasonable care to prevent and detect hazards, which in practice means regular site walks, flagging violations, and following up to confirm they are fixed.3Occupational Safety and Health Administration. CPL 2-0.124 – Multi-Employer Citation Policy A large, fast-moving site demands more frequent inspections than a small renovation.
Construction’s most lethal hazards are falls, struck-by incidents, caught-in-between accidents, and electrocutions. OSHA’s construction standards under 29 CFR Part 1926 set detailed requirements for fall protection, scaffolding, excavation shoring, electrical safety, personal protective equipment, and hazard communication.4Occupational Safety and Health Administration. 29 CFR 1926 – Safety and Health Regulations for Construction The general contractor does not need to be an expert in every subcontractor’s trade, but they do need to recognize obvious hazards and act on them.
Penalties are steep. OSHA fines for willful or repeated violations reach $165,514 per violation.5Occupational Safety and Health Administration. OSHA Penalties Those penalties hit the general contractor as the controlling employer, not just the subcontractor whose crew was exposed.
Tax Reporting and Worker Classification
General contractors operate as businesses, and the IRS expects them to report payments to subcontractors the same way any other business reports payments to independent contractors. For tax years beginning after 2025, the reporting threshold on Form 1099-NEC rose to $2,000, up from the longtime $600 floor.6Internal Revenue Service. 2026 Publication 1099 Any subcontractor paid $2,000 or more in a calendar year must receive a 1099-NEC.7Internal Revenue Service. Instructions for Forms 1099-MISC and 1099-NEC
Worker classification is where contractors get into the most expensive tax trouble. The IRS applies a common-law control test asking whether the hiring party controls how, when, and where the work is performed. Who provides the tools, whether the worker can take jobs from other companies, how payment is structured, and whether the relationship is ongoing or project-based all matter.8Internal Revenue Service. Worker Classification 101: Employee or Independent Contractor The Department of Labor uses a broader “economic reality” test under the Fair Labor Standards Act that can reach workers the IRS test might not.9Federal Register. Employee or Independent Contractor Status Under the Fair Labor Standards Act, Family and Medical Leave Act, and Migrant and Seasonal Agricultural Worker Protection Act
A contractor who treats workers as subcontractors when they should legally be employees is on the hook for back withholding, Social Security and Medicare contributions, unemployment taxes, and penalties. The IRS runs a Voluntary Classification Settlement Program that offers partial relief from past employment tax liability for businesses willing to reclassify workers going forward, but partial relief still means writing a check.
Hiring Without a License
One thing property owners should know before signing anything: in a state that requires licensure, operating as a general contractor without a license is not a technicality. Penalties range from misdemeanor fines to felony prosecution carrying up to five years in prison, and some states impose per-day civil penalties for each day of unlicensed work. In many states an unlicensed contractor cannot legally enforce a construction contract at all, meaning if the owner refuses to pay, the contractor has no right to sue. Hiring one also risks voided insurance coverage, liability for unpermitted work, and complications years later when a title company or buyer’s inspector takes a close look at the property. Every state with a licensing board maintains a public lookup tool, and verifying a license takes under a minute.
