Start a trade business

How to start a general contracting business

A general contractor sells management, not just labor: building a sub bench, writing owner contracts and subcontracts, controlling the schedule, and handling the money between the owner and the trades.

To start a general contracting business, get the experience and license your state requires for the size of work you want, form and register the company, buy general liability and workers' compensation coverage, build a bench of reliable subcontractors with paperwork in order, prepare owner contracts and subcontract forms, set up bonding if you will bid public work, and put job costing, billing, and change order systems in place before the first contract. The core skill of a GC is coordinating other people's work and money. Plan the business around that.

What a general contractor actually sells

A general contractor holds the prime contract with the owner and is responsible for delivering the whole project. Most GCs self-perform some work (often carpentry, concrete, or general labor) and subcontract the rest. The owner pays the GC; the GC pays the subs. That puts the GC in the middle of every schedule conflict, every change, and every payment.

Picture a $480,000 tenant improvement. The GC carries eight or nine subcontracts (demo, framing and drywall, electrical, plumbing, HVAC, fire sprinkler, flooring, paint, ceilings), its own general conditions, and a fee. If the GC does not catch a scope gap between the HVAC and electrical bids, the GC pays for it. If the owner pays late, the subs still call the GC. That is the business.

Step by step: starting a GC company

  1. Get the right experience. Many states require proof of experience to sit for a general contractor license, and GC licenses are often tiered by project size or type. Running jobs as a superintendent or project manager for another GC is the most common path.
  2. Write the plan. Include target project types and sizes, the sub trades you will rely on, what you will self-perform, and how much working capital you have. The U.S. Small Business Administration's traditional plan format includes market analysis, organization and management, funding request, and financial projections. See how to write a construction business plan.
  3. Form and register the company. Register an LLC or corporation with your state and appoint a registered agent, then get a free EIN from the IRS.
  4. Get licensed. Check the state license class that matches your project size and any local registration. Start at contractor license requirements by state.
  5. Buy insurance. General liability, workers' compensation (required for businesses with employees, per the U.S. Small Business Administration, along with unemployment and disability insurance), commercial auto, and builder's risk when your contract requires it. Owners and lenders will check your certificates.
  6. Set up bonding. Public owners usually require bid, performance, and payment bonds. A surety looks at your financial statements, experience, and character. The U.S. Small Business Administration's Surety Bond Guarantee program can help small contractors on contracts up to $9 million for non-federal work and $14 million for federal work. See how bonding capacity is calculated.
  7. Prepare your contract forms. An owner-contractor agreement, a subcontract with flow-down clauses, change order forms, and lien waiver forms. Have an attorney review them for your state. See what to include in a subcontract agreement.

Build the subcontractor bench

A GC is only as good as its subs. Before bidding, line up at least two subs in every trade you do not self-perform. Collect each one's license, certificate of insurance, W-9, and safety information, and set reminders for expiration dates. Pay them on time, because the best subs choose which GCs to work for. See how to prequalify subcontractors and how to track subcontractor insurance certificates.

Write a clear scope of work for each trade on every bid. Most fights between GCs and subs start with an item that both sides assumed was in the other's price: blocking, firestopping, final cleaning, access panels. A scope sheet that lists inclusions and exclusions by trade catches those gaps before the contract, when they are cheap to fix.

Pricing as a general contractor

A GC bid is built from subcontractor quotes, self-performed work, general conditions (supervision, temporary facilities, cleanup, dumpsters, permits, insurance), overhead, and fee. Level sub bids line by line so you are comparing the same scope. Price general conditions by the week of duration, because a job that runs four weeks long costs four more weeks of supervision. See how to price general conditions and how to level subcontractor bids.

Watch the payment terms as closely as the price. If the owner contract pays in 30 days and holds 10 percent retainage, but your subcontracts promise payment in 15 days with 5 percent retainage, the GC finances the gap on every job. Match the terms, use pay-when-paid or pay-if-paid language only where your state allows it, and know your cash position before you sign. See pay-if-paid vs pay-when-paid clauses explained.

Systems a GC needs from day one

  • Pay applications and retainage, both from the owner and to every sub. See how progress billing works.
  • Change order control, from owner change to sub change, priced and signed before the work.
  • Job costing and WIP, so you know which jobs are over- or underbilled. See WIP report.
  • RFIs, submittals, and daily logs, the record that protects you in disputes.
  • Lien waivers and compliance, collected with every sub payment.

Smart Business Automator covers these for small and mid-sized GCs: project tracking, invoicing, change orders, subcontractor tracking, job costing with WIP views, compliance and certified payroll preparation, and AI help drafting RFIs and summarizing daily logs. See subcontractor compliance automation.

Mistakes new general contractors make

  1. Bidding work above the license class or bonding capacity.
  2. Accepting the low sub bid without checking for scope gaps.
  3. Signing owner contracts with terms the subcontracts do not flow down.
  4. Paying subs before collecting their lien waivers and certificates.
  5. Underpricing general conditions and supervision.
  6. Letting change orders pile up unsigned until the end of the job.

Frequently asked questions

Do I need a license to be a general contractor?

Most states license general contractors, often with classes based on project size or type, and many cities add local registration. Check your state licensing board before bidding.

How much experience do I need to start a GC business?

Many state licenses require documented construction experience, and sureties and owners look for it too. Running projects for another GC is the usual way to build it.

How do general contractors make money?

Through fee or markup on the total cost of the work, margin on self-performed work, and general conditions priced to cover supervision and site costs. Profit depends on controlling scope, schedule, and change orders.

What is the difference between starting a GC company and a trade company?

A trade company sells its own labor and material. A GC sells coordination of many trades and carries the risk of their scope gaps, schedule, and payment. That needs stronger contract, sub management, and billing systems.

Do new general contractors need bonding?

Only for work that requires it, which includes most public projects and some private ones. Start building a surety relationship early with clean financial statements.
