How to Start a General Contractor Business
General contracting is a high-ticket trade built on licensing, relationships, and project management. You coordinate subs, materials, schedules, and clients, so the business runs on organization as much as construction skill. Here is how to start one.

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 cost | Typical 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
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
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
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
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
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
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.
| Service | Typical 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 orders | billed separately |
| Progress draws | tied 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
What year one actually looks like
The parts of general contracting work nobody warns you about, which show up once you have customers rather than while you are deciding whether to start.
Two jobs running at once is the first real wall
One project is a series of decisions you can hold in your head. Two overlapping ones need written schedules, because the tile setter who slips a day on the first has just moved four trades on the second. Most contractors hit this before their tenth job.
You own the gaps between everyone else's schedules
Each trade on site keeps its own calendar and none of them is arranging the sequence. Waiting for an inspection, a delivery or a sub who took another job is unproductive time that still costs you, and closing those gaps is most of what the job actually is.
Following up on sent bids is the cheapest work available
Estimates go quiet for ordinary reasons and a large share of them will close on a second conversation. New contractors spend their evenings writing new bids instead, which is far more work for the same revenue, and the old ones simply expire.
Run it like a business from day one
The operators who pull ahead in any trade are the ones who systematize the boring parts, meaning booking, scheduling, invoicing, payments and reviews. Smarfle is the all-in-one CRM built for general contracting operators, so you can take on more work without drowning in admin.
