A general contractor can perform and manage the physical construction of a building whenever the job involves at least two unrelated building trades, which covers framing, carpentry, drywall, siding, insulation, flooring, and the structural work that holds a building up. What a general contractor can do also includes pulling permits, hiring and sequencing subcontractors, and running the project through inspections to final sign-off. What they cannot do, in almost every state, is take a standalone contract for electrical, plumbing, HVAC, or gas work. Those jobs require a separately licensed specialty tradesperson.
Building Work a General Contractor Can Self-Perform
The core of the scope is the physical assembly of a structure meant to shelter people, animals, or property. That means wood or steel framing, rough carpentry, subfloor and finish flooring, drywall hanging and finishing, exterior siding, and insulation. Most licensing frameworks let a general contractor self-perform framing and carpentry without a separate specialty license, which matters because those tasks make up a large share of any residential or light commercial project.
The “two unrelated trades” rule is what separates a general contractor from a specialty contractor. A crew that only frames isn’t operating as a general contractor. A contractor who frames the walls, hangs the sheathing, installs drywall, and lays flooring is combining trades in a way that falls squarely within a general building license.
Roofing sits in an unusual spot. On a larger project that already involves two or more unrelated trades, the general contractor can typically include roofing in the overall scope. A standalone roofing contract, with no other trades involved, usually requires a dedicated roofing license.
Load-bearing work gets extra scrutiny because mistakes are expensive and dangerous. Foundations, bearing walls, headers over openings, and roof trusses or rafters all fall to the general contractor, and building inspectors verify compliance at multiple stages before the project can move forward.
Hiring Subs, Running the Schedule, and Handling Change Orders
A general contractor’s real value often has less to do with swinging a hammer and more to do with orchestrating everyone else who does. On any project involving electrical, plumbing, HVAC, concrete, tile, painting, and a half-dozen other trades, the general contractor decides when each crew shows up, how long they have, and what condition the site needs to be in before they start. Get that sequencing wrong and you end up paying a plumber to stand around waiting for framing to finish.
Hiring subcontractors is a core responsibility. The general contractor evaluates each sub’s licensing, insurance, and track record, then negotiates scope and pricing before the sub ever touches the site. Once work begins, quality control falls on the general contractor. Every task a subcontractor performs needs to match the architectural plans and contract specifications. When something doesn’t line up, the general contractor stops the work, demands corrections, and absorbs the schedule hit. Experienced contractors build buffer time into the schedule specifically for rework.
Change orders are built into this job. When an owner wants to upgrade finishes, or an unforeseen site condition forces a design adjustment, the general contractor documents the change, prices it, and gets written approval before any new work begins. Skipping the written approval is one of the most common mistakes in construction. Courts have consistently held that contractors who proceed with extra work based on verbal agreements risk not getting paid, and owners who silently allow unapproved work may still end up owing for it. The safest approach for both sides is a signed change order that spells out the revised scope, cost impact, and any schedule extension before anyone picks up a tool.
Permits, Inspections, and Code Compliance
Pulling building permits is one of the general contractor’s most important administrative duties. Before any physical work begins, the contractor submits plans to the local building department, pays the applicable fees, and waits for approval. For a typical residential job, permit fees run roughly $500 to $3,000, with large or complex projects running considerably higher. The permit confirms the proposed work meets local zoning requirements and safety standards before ground is broken.
Once the permit is issued, the project enters a cycle of build-and-inspect. Local building officials visit the site at specific milestones to verify the work matches the approved plans and complies with adopted building codes. A standard sequence looks like this:
- Foundation inspection, after footings are dug and forms are set but before concrete is poured, covering soil conditions, rebar placement, and drainage.
- Framing inspection, once the structural frame is up but before insulation and drywall go in, covering wall heights, header sizes, joist spacing, and shear panel placement.
- Mechanical inspections of electrical, plumbing, and HVAC rough-ins before they get buried behind walls.
- Final inspection of the completed building for code compliance, safety, and habitability before an occupancy certificate is issued.
Work cannot proceed past any of these checkpoints until the inspector signs off. Covering up framing before the framing inspection, for example, can trigger a stop-work order and a requirement to tear out drywall so the inspector can see the structure. Fines for code violations or unpermitted work can reach several thousand dollars, and in serious cases the municipality can require demolition of non-compliant construction. The general contractor schedules these inspections and makes sure the site is ready when the inspector arrives.
Work That Requires a Specialty License
This is the hard boundary. A general contractor cannot accept a standalone contract for electrical work, plumbing, HVAC installation, or gas line work. These trades involve systems where mistakes create fire hazards, flooding, carbon monoxide exposure, or electrocution risk, and every state requires separate specialty licenses for the people who install and repair them.
The distinction between “part of a larger project” and “standalone” matters. When a general contractor is building a house, the project naturally includes electrical, plumbing, and HVAC work. The general contractor can include those trades in the overall contract and manage the schedule, but has to hire licensed specialty subcontractors to perform the actual installation. What a general contractor cannot do is accept a contract solely to rewire a kitchen, replace a sewer line, or install a new furnace. Those are specialty contracts that require the corresponding license.
Penalties for crossing this line are serious. Depending on the state, performing work outside the scope of a license can result in misdemeanor or even felony charges, with fines that can reach hundreds of dollars per day of unauthorized work. Some states add civil penalties on top of criminal ones. A general contractor caught performing specialty work risks suspension or revocation of their license, which effectively shuts down the business.
Safety Responsibility Across the Entire Site
General contractors carry safety obligations that extend well beyond their own employees. Under OSHA’s multi-employer citation policy, a general contractor who controls a construction site can be cited for safety hazards created by subcontractors, even when the general contractor’s own workers aren’t the ones at risk. On most sites, the general contractor is the controlling employer.
That role means exercising reasonable care to detect and correct hazards across the entire site: regular safety walkthroughs, enforcing fall protection and hard hat requirements, making sure trenches are properly shored, and stopping work when conditions are dangerous. Failing to do so can produce OSHA citations and fines directed at the general contractor, not just the subcontractor whose crew created the hazard.
Workers’ compensation adds another layer. If a subcontractor doesn’t carry workers’ compensation insurance and one of their workers is injured on the job, the general contractor can be held financially responsible for medical expenses and lost wages. That is why experienced contractors require every subcontractor to provide a certificate of insurance before setting foot on the site and verify coverage stays active throughout the project.
Warranty Obligations After the Build
Finishing a project doesn’t end a general contractor’s legal exposure. Most states recognize implied warranties on new construction, and many builders also provide express written warranties. The industry-standard structure breaks into three tiers:
- One year for workmanship and materials, covering issues like paint defects, gaps in trim, or cabinet hardware that fails.
- Two years for mechanical systems, including electrical, plumbing, and HVAC distribution.
- Ten years for major structural defects, such as a failing foundation, load-bearing wall failure, or roof structure collapse.
Beyond express warranties, most states also impose statutes of repose that set the outer limit on when a construction defect claim can be filed. These range from about 4 years to 15 years depending on the state, measured from the date of substantial completion. A homeowner who discovers a foundation crack in year eight can still bring a claim in a state with a ten-year repose period, even if the express warranty expired years earlier. Liability can linger long after the final inspection.
Insurance and Bonding the Contractor Must Carry
Most states require a general contractor to carry general liability insurance and a surety bond before issuing a license. These are the financial safety net that protects property owners and the public when things go wrong on a job site.
General liability insurance covers property damage and bodily injury caused by the contractor’s work. Minimum coverage amounts vary by state and are often tied to the dollar value of projects the contractor is licensed to take on. A contractor licensed for smaller residential work might carry $100,000 in coverage, while one handling multi-million-dollar commercial projects typically needs $1,000,000 or more. Contractors also carry workers’ compensation insurance for their own employees.
Surety bonds do something different. A contractor’s license bond guarantees the contractor will follow state licensing laws and fulfill contractual obligations, with bond amounts running from as low as $2,500 in some states to $100,000 or more in others, depending on the type and size of work. On larger projects, owners or lenders may also require performance bonds, which guarantee completion, and payment bonds, which guarantee subcontractors and suppliers get paid. Performance bond premiums typically run between 0.5 and 2.5 percent of the contract amount, with smaller projects paying rates toward the higher end of that range.
