What it is

You put up ready-made garage kits (wood, steel or vinyl-clad) on a slab or foundation the customer already has or you arrange. Work includes the frame, siding, roof, doors and finishing.

Your first three steps

  1. Check your state and county contractor licensing rules and which job sizes they cover
  2. Get general liability insurance and a trailer-ready tool kit, then line up one or two helpers
  3. Contact local kit dealers and lumber yards and offer to be their recommended installer
Who pays

Homeowners who bought a kit from a dealer or big-box store and want it built, plus kit dealers who need reliable installers.

How it makes money

A fixed installation fee per garage, usually based on size and kit type. Extras such as pad prep, electrical referrals and painting add to the job.

Skills that help
  • Basic carpentry and framing
  • Reading kit plans and instructions
  • Safe lifting and working at height
  • Clear quotes and customer communication
Watch out for
  • Contractor license requirements, which vary by state and sometimes by job value
  • Building permits, zoning, setbacks and HOA rules before any build starts
  • General liability insurance, plus workers' compensation once you hire help
  • Weather delays, missing kit parts and who pays for them, so put it in your contract
  • Foundation quality, since a poor slab from someone else can become your problem
