A contractor in real estate is an independent business hired under a formal contract to perform construction, renovation, or repair work on a property. Unlike an employee, the contractor brings their own crew, materials, tools, and expertise, and controls how the work gets done. The property owner specifies the finished result; the contractor delivers it. That legal distinction shapes who pays taxes, who carries insurance, who pulls permits, and who is liable when something goes wrong on the job site.
Contractor vs. Employee: Why the Distinction Matters
The IRS classifies contractors based on who controls the work. When you hire a contractor, you can specify the outcome you want, but you don’t dictate the daily schedule, choose the tools, or direct the step-by-step methods. That autonomy over how the work gets done is what separates an independent contractor from an employee under federal law.1Internal Revenue Service. Independent Contractor (Self-Employed) or Employee?
The practical consequences follow from that. Property owners don’t withhold income tax, pay Social Security contributions, or provide benefits for independent contractors the way they would for employees. The contractor handles all of that through self-employment tax filings and their own insurance policies. Misclassifying an employee as an independent contractor can expose the hiring party to back taxes and penalties, so the label is not just a formality.
General Contractors and Subcontractors
Most construction projects run through a two-tier structure. The general contractor holds the master contract with the property owner and is responsible for delivering the finished project on time and within budget. They are the single point of accountability.
To handle specialized work like electrical wiring, plumbing, or HVAC installation, the general contractor hires subcontractors under separate agreements. These trade-specific professionals answer to the general contractor, not to the property owner. The contractual chain flows from owner to general contractor to subcontractor, which simplifies communication but also means the general contractor is on the hook when a subcontractor’s work falls behind schedule or fails to meet specifications.
Trades that involve safety systems, such as electrical and plumbing, usually require credentials beyond a basic contractor license. Electricians, for instance, typically progress through apprentice, journeyman, and master certifications. A journeyman can work independently; a master electrician can pull permits, supervise other electricians, and take on the most complex projects.
What a Contractor Actually Does on the Job
The day-to-day role is part construction manager, part bureaucrat. Before any work begins, the contractor secures building permits from the local building department. Working without permits is one of the clearest red flags in the industry: unpermitted work can trigger fines, void insurance coverage, and even force you to tear out finished construction.
During the build, the contractor coordinates inspections at each major phase. Inspectors typically need to sign off on foundation work, framing, electrical rough-in, plumbing, and insulation before walls close up. Skipping an inspection means either ripping open finished work later or facing code violations that surface when you try to sell the property.
Most jurisdictions base their building standards on the International Building Code or the International Residential Code, adapted with local amendments. The contractor is responsible for knowing which version applies and ensuring the work meets every applicable standard, from structural load requirements to fire-resistance ratings to energy efficiency. When an inspector flags a deficiency, the contractor corrects it and schedules a re-inspection. That cycle repeats until every phase passes, the building department issues a certificate of occupancy, and the project is legally complete.
How Contractors Get Paid
How a contractor gets paid depends on the contract type, and choosing the wrong one for a project can cost real money. Two structures dominate:
- Fixed-price (lump sum). You and the contractor agree on a total price before work starts, with the contractor’s profit built in. If the job comes in under budget, the contractor keeps the savings. If costs run over, the contractor absorbs the loss. This works best when the scope of work is well-defined and unlikely to change.
- Cost-plus. You pay the contractor’s actual expenses for labor, materials, and equipment, plus a separate fee or percentage markup for profit. The final price isn’t known until the project wraps. This offers flexibility when the full scope is hard to predict, but it requires trust and transparency.
Regardless of structure, the contract should spell out how change orders work. Change orders are formal amendments that adjust the scope or price when unexpected conditions arise, such as hidden water damage behind a wall. Getting those terms in writing before work begins prevents the payment disputes that derail so many projects.
Licensing: Why It Matters to the Owner Too
Licensing requirements vary by state and sometimes by city or county. In most jurisdictions, a general contractor needs to pass a trade exam, demonstrate a certain number of years of hands-on experience, and show financial stability through net worth disclosures or audited financial statements. Initial application fees typically range from a few hundred to several thousand dollars depending on the license class and jurisdiction.
Working without a valid license exposes the contractor to civil fines and, in many states, makes the underlying contract unenforceable. That last consequence is the one that bites hardest: an unlicensed contractor may lose the legal right to collect payment for work already completed. For property owners, hiring an unlicensed contractor creates its own risks. Homeowner’s insurance policies frequently exclude coverage for damage caused by unlicensed work, and you may have limited legal recourse if the job falls apart.
Before signing anything, verify the license with the issuing state agency. Most states offer a free online lookup. Confirming the license is current, in the correct classification for your project, and free of disciplinary actions takes a few minutes and prevents the worst outcomes.
Insurance and Performance Bonds
Three types of financial protection show up in virtually every serious construction project.
General liability insurance covers damage to third-party property and bodily injury on the job site. If a contractor’s demolition work sends debris through your neighbor’s window, general liability pays for it. What it does not cover are mistakes in the contractor’s professional judgment, such as a roof designed with the wrong load capacity. That gap is where professional liability insurance (sometimes called errors and omissions coverage) comes in, though not all contractors carry it.
Workers’ compensation insurance covers medical costs and lost wages when a laborer gets hurt on the job. Nearly every state requires employers, including contractors with employees, to carry this coverage. Without it, an injured worker’s medical expenses could become the property owner’s problem, particularly if the owner failed to verify coverage before the project started.
Performance bonds work differently from insurance. A performance bond is a guarantee from a third-party surety company that the contractor will finish the project according to the contract terms. If the contractor abandons the job or goes bankrupt, the surety either completes the work or pays for someone else to finish it. Federal law requires both performance and payment bonds on any government construction contract exceeding $100,000.2Office of the Law Revision Counsel. 40 U.S. Code 3131 – Bonds of Contractors of Public Buildings or Works Private projects have no universal federal bonding mandate, but many owners on larger commercial builds require them anyway. Bond premiums typically run around 1% of the contract value, with smaller projects paying proportionally more.
Mechanic’s Liens: The Risk Most Owners Miss
One of the most consequential risks in any construction project is the mechanic’s lien, a legal claim that contractors, subcontractors, and material suppliers can file against your property when they don’t get paid for their work or materials. Every state has some version of this tool.
Here is the uncomfortable part: a subcontractor can place a lien on your property even if you’ve already paid the general contractor in full. If the general contractor pockets the money instead of paying the sub, the subcontractor’s dispute becomes your problem. The lien attaches to the property itself, clouding the title and blocking sale or refinancing until the debt is resolved.
The best defense is requiring lien waivers at each payment milestone. A conditional lien waiver is a document in which the contractor or subcontractor agrees to release their lien rights for a specific payment amount once the check clears. Collecting these waivers with every progress payment builds a paper trail that prevents double-payment situations. Filing deadlines, notice requirements, and rules about which property types are covered vary significantly by state, so understanding your state’s lien laws before the first payment goes out is worth far more than any amount of cleanup afterward.
The Three-Day Cancellation Window
If a contractor signs you up for home improvement work at your residence rather than at their office, federal law gives you three business days to cancel. The FTC’s Cooling-Off Rule requires the contractor to disclose this cancellation right in writing at the time you sign.3Federal Trade Commission. Cooling-Off Period for Sales Made at Home or Other Locations The rule applies to contracts exceeding $25 that are signed outside of the seller’s permanent business location. Once the three-day window closes, you lose this particular escape hatch. If you feel pressured into signing something at your kitchen table, use those 72 hours.
