What it is

You act as the general contractor for a private client's custom home. You price the job, manage permits, hire trade subcontractors such as framers, electricians and plumbers, order materials, keep the schedule and check quality through to handover.

Your first three steps

  1. Check your state's contractor licensing board for the license class needed to build homes, and what experience or exam it requires
  2. Get quotes for general liability insurance, workers' compensation (once you hire) and any required surety bond
  3. Build relationships with a few reliable subcontractors, an architect or designer and a local lender, then write a simple sample contract with a lawyer's review
Who pays

Private landowners and families building a home on their own lot, often working with an architect or designer. Some are move-up buyers or retirees.

How it makes money

Usually a fixed price contract or cost-plus contract with a builder's fee or markup. Clients pay in stages (draws) as the build progresses, so cash flow needs careful planning.

Skills that help
  • Reading plans and estimating costs
  • Scheduling and managing subcontractors
  • Clear communication with clients
  • Basic knowledge of building codes and construction methods
Watch out for
  • State contractor license rules and any local business license, which vary by state, county and city
  • General liability insurance, builder's risk insurance and workers' compensation once you have employees
  • Cost overruns on fixed price contracts, so build in contingencies and use written change orders
  • Cash flow gaps between paying subcontractors and receiving client draws
  • Check lien rules and warranty requirements in your state, and have a lawyer review your contracts
