How to Start a General Contracting Business: 2026 Step-by-Step Guide

What it takes to run your own jobs

Learning how to start a general contracting business comes down to eight moves: pick a lane, write a plan, register the entity, get licensed, get bonded and insured, build a bench, price for margin, and quote fast. Every number in this guide traces to the Bureau of Labor Statistics, the Small Business Administration, or the IRS, so you can verify every claim.

The demand is real. The BLS projects employment of construction managers, the occupation that covers self-employed general contractors, to grow 9 percent from 2024 to 2034, with about 46,800 openings each year, and the median construction manager earned $106,980 in May 2024. The BLS also notes that people with a high school diploma and trade experience may be more likely to work as self-employed general contractors, so the experience you already have is the foundation.

How to start a general contracting business in 8 steps

The steps run in order because each unlocks the next: no bank account without an entity and an EIN, no legal bids without a license, no bigger jobs without bonding. This is how to start a general contracting business without a compliance surprise.

1. Pick your lane and validate demand

   Decide what you build before anything else. Residential remodels and additions are the most common entry point: smaller jobs, short sales cycles, and one happy homeowner refers the next. Count real demand in your area first, then expand as your track record and bonding capacity grow.

2. Write a one-page plan and startup budget

   Skip the 40-page plan. One page answers four questions: what you build, who buys it, what it costs to start, and what revenue target makes the year worth it. List license fees, bonds, insurance, a vehicle, tools, and software honestly, then reverse-engineer the target into projects per year.

3. Choose a legal structure and register it

   Per the SBA, a sole proprietorship is easy to form but leaves you personally liable for the debts of the business, while an LLC protects personal assets in most lawsuit and bankruptcy scenarios. A general contractor answers for subcontractors and jobsite safety, so most skip the sole proprietorship. Register the entity with your state.

4. Get an EIN and open a business bank account

   An EIN is your federal tax ID, and the IRS issues it free in minutes at IRS.gov, so never pay a third-party site for it. You need one to hire employees or run a corporation or partnership. Open a dedicated business checking account the day the EIN arrives.

5. Get your general contractor license

   Most states require a general contractor license above a dollar threshold, often with a trade exam plus a business and law exam, and rules vary by state and city. Check your state licensing board and local building department before you bid, because unlicensed contractors often cannot enforce a contract in court.

6. Get bonded and insured

   A license bond is often required to get licensed at all, and bid or performance bonds unlock public and larger private work. The SBA guarantees bid, performance, and payment bonds for small contractors who might not qualify on the open market. Carry general liability from day one and add workers’ compensation when you hire.

7. Build your subcontractor and supplier bench

   A general contractor wins by coordinating other people’s labor. Vet every electrician, plumber, framer, and finish crew for license, insurance, and references, because their work becomes your liability. Open accounts at the supply houses you buy from most for contractor pricing, credit, and same-day material.

8. Price for margin, then quote fast

   Build every bid from the cost up: burdened labor, real material prices, subcontractor quotes, then overhead and a target margin set by project type and risk. Owners reward the contractor who sends a clear, itemized proposal first. Our guide to how to bid a construction job breaks down the full bid.
