How to Start a General Contractor Business

Is a general contracting business worth starting?

Construction demand tracks housing and remodeling activity, and the building trades are projected to keep growing, so well-run contractors have steady work.

How much does it cost to start?

A typical general contracting business costs $5,000 to $50,000 to start. Licensing, bonding, insurance, and working capital to float materials and subs before you get paid are the real costs. Tools matter less than cash flow.

Startup costTypical range
Contractor license + exam + fees$300 to $3,000
Surety bond$100 to $1,000 / year (premium)
General liability + workers' comp$2,000 to $10,000 / year
Working capital (materials, subs)$5,000 to $30,000
Software, estimating, website$500 to $3,000

Ranges are typical and vary by market and scope. Confirm licensing costs with your state.

How much can you earn?

General contractors' income swings widely with project volume and margin; a solo remodeler might net $60,000 to $120,000, while a contractor running multiple crews clears far more. Profit lives in estimating accuracy and change-order discipline, not job count.

How to start a general contracting business, step by step

  1. 1

    Get licensed and bonded

    Most states require a general contractor or builder license, often with an exam, proof of experience, and a surety bond. Licensing thresholds vary by project size, so check what your state requires for the work you plan to take.

  2. 2

    Set up insurance and a legal entity

    Form an LLC, carry general liability, and add workers' comp if you have employees. Bonding protects clients and is often required to pull permits. Get your contracts reviewed; clear scope and payment terms prevent most disputes.

  3. 3

    Build your subcontractor bench

    You are only as good as your subs. Line up reliable electricians, plumbers, HVAC, framers, and finishers before you need them, and treat them well so they prioritize your jobs.

  4. 4

    Master estimating and bidding

    Accurate estimates are the difference between profit and loss. Break jobs into labor, materials, subs, permits, and margin, and track change orders rigorously; uncontrolled scope creep is what sinks projects.

  5. 5

    Find your first projects

    Start with remodels and smaller jobs to build a portfolio and reviews. A Google Business Profile, referrals, realtor and designer relationships, and a portfolio of finished work bring in the next ones.

  6. 6

    Manage projects without the spreadsheet chaos

    Estimates and proposals, change-order tracking, scheduling across subs, progress billing, and a client-facing record of the job keep multi-phase projects on time and paid. Organization is the contractor's real product.

Licensing and insurance

Most states require a general contractor or builder license, frequently with an exam, documented experience, and a surety bond; some license by project dollar threshold. You will also need general liability and (with employees) workers' comp. Permits are pulled per project. Verify with your state contractor licensing board.

How to price your work

Contractors typically price cost-plus (materials + labor + subs + a 10% to 20% margin) or fixed-bid per project. Track change orders separately and bill in progress draws tied to milestones so you are never floating the whole job on your own cash.

ServiceTypical price
Markup on cost (cost-plus)10% to 20%
Small remodel project$5,000 to $30,000
Kitchen / bath remodel$15,000 to $75,000+
Change ordersbilled separately
Progress drawstied to milestones

Example prices are typical U.S. ranges and vary by region, scope, and demand.

Pros and cons of starting a general contracting business

Pros

  • High-ticket revenue per project
  • Steady demand from housing and remodeling
  • Scales by adding crews and subs, not your own hours
  • Relationships compound into referrals

Cons

  • - Licensing, bonding, and insurance to start
  • - You float materials and subs before getting paid (cash-flow risk)
  • - Margins lost to bad estimates and scope creep
  • - Project management is the real, hard job

Common mistakes to avoid

  • Under-bidding because the estimate missed labor, permits, or subs
  • Not tracking change orders (uncontrolled scope sinks projects)
  • Floating the whole job on your cash instead of billing progress draws
  • Relying on unreliable subs you lined up at the last minute

Frequently asked questions
