Starting a General Contracting Business typically costs between $10,000 and $75,000 (SBA, 2025), depending on your state's licensing path, the surety bond your work requires, and whether you run residential remodels or chase commercial projects. The $10,000 version is a handyman-turned-GC with a license, a license bond, general liability, a used truck, and a trade-account at the lumber yard. The $75,000 version is a residential remodel or new-construction GC with a higher bond, workers comp for a small crew, a second truck and trailer, estimating and project-management software, and the working capital to pay subs before the first owner draw clears. A general contractor earns a markup on the job, usually 10-20% of project cost, on work that ranges from a $15,000 bathroom remodel to a $500,000+ custom home.

Detailed Cost Breakdown
License, Exam & Surety/License Bond - $700 to $8,000
Most states require a general contractor or B license before you can pull permits or sign a contract above a dollar threshold. The path usually runs trade exam plus law-and-business exam, a few years of documented experience, and a fee. California's CSLB charges roughly $450 in application and license fees and requires a $25,000 contractor bond (CSLB, 2025); Florida's state certified GC license runs a similar exam-and-fee track; many states cap licensing at the county or city level for smaller residential work. Budget $200-$600 for exam prep courses and $100-$400 in application and exam fees. The license bond (often $15,000-$25,000 of coverage) costs you only the annual premium, usually 1-5% of the bond amount, so $150-$1,250 a year depending on your credit. Do not confuse the license bond with a project surety bond, covered below. Form an LLC or S-corp ($40-$520 in state filing fees) before you sign anything, because a single construction-defect claim can outlive the project by a decade.
Insurance (GL + Workers Comp deposits) - $1,500 to $12,000
General liability for a contractor runs $1,200-$5,000 a year for a solo operator and climbs with revenue and risk class. Roofing, framing, and any work at height price higher than kitchen-and-bath remodels. Workers comp is the line that surprises new GCs: it is priced per $100 of payroll by trade code, and the rate for a high-risk code like roofing can run several times the rate for finish carpentry. Even if you hire only subcontractors, most states make you carry comp or collect a current certificate of insurance from every sub, because an uninsured sub's injury rolls onto your policy at audit. Carry a builder's risk policy on the structure during construction and name the owner and lender as additional insured. First-year insurance deposits and the first quarter or two of premium are real cash out the door before a single invoice gets paid.
Truck, Trailer & Field Tools - $3,000 to $30,000
A GC manages and coordinates more than swings a hammer, so the tool list is lighter than a specialty trade's. Most subs bring their own tools and ladders. You need a reliable work truck ($3,000-$25,000 used to new), a trailer for hauling materials and debris ($1,500-$6,000), and a core kit: a laser level, a good tape and layout tools, a cordless drill and impact set, a circular saw, a job-site table saw, ladders, and a generator for sites without power. A site office trailer or a locking job box protects tools and documents on larger projects. New GCs overspend here. Buy the truck used, rent the rare tool you need twice a year, and put the saved capital into working capital instead, because an undercapitalized GC fails before an under-equipped one does.
Estimating & Project Software Setup - $300 to $3,000
The job that wins money is the estimate, and the job that loses it is the one you bid in a spreadsheet and forgot a line item. Takeoff and estimating software prices a project from plans and tracks change orders against the original bid. Buildertrend and CoConstruct run $99-$399 a month and bundle estimating, scheduling, client portals, and selections, which residential remodelers and custom builders lean on. Procore is built for commercial and larger jobs and prices on annual construction volume, often several thousand dollars a year. A solo GC can start with QuickBooks plus a basic takeoff tool and a shared schedule, then graduate to a full platform once the job count justifies it. Annual setup, training, and the first months of subscription land in startup cost.
Marketing, Office & Launch - $500 to $4,000
Most GC work comes from referrals, repeat clients, and a strong Google Business Profile with project photos and reviews. A clean website with a portfolio of completed jobs ($100-$1,500) closes leads that find you. Vehicle lettering, yard signs on active job sites, and a presence on Houzz and Angi feed the residential pipeline. Builder's accounts at the lumber yard, the plumbing supply house, and the electrical distributor are worth setting up early because they extend net-30 terms that smooth cash flow. Branded estimates, a contract template reviewed by a construction attorney, and a basic CRM round out the launch.
Working Capital (pay subs before draws) - $4,000 to $18,000
This is the line that decides whether a GC survives year one. You pay subcontractors and material suppliers on their terms, often before the owner's draw or progress payment clears, and the owner withholds retainage on top. A GC who books a $60,000 remodel can be $20,000 out of pocket on subs and materials before the second draw funds. Carry two to three months of fixed costs plus a float for the gap between paying subs and getting paid. A line of credit or supplier net-30 terms covers part of the gap, but cash reserves cover the rest, and the GCs who run out of cash mid-project are the ones who never finish.
Monthly Operating Costs
| Expense | Low Estimate | High Estimate |
|---|---|---|
| Insurance (GL + comp, allocated) | $150/mo | $1,400/mo |
| Software (estimating + accounting) | $50/mo | $500/mo |
| Truck, fuel & maintenance | $300/mo | $1,200/mo |
| Office, phone & supplies | $100/mo | $600/mo |
| Marketing & lead services | $100/mo | $800/mo |
| Total Monthly | $700/mo | $4,500/mo |
Business Models and How They Change the Math
The kind of work you take decides your bond, your insurance class, your cash-flow gap, and how much capital you need before the first job.
Residential Remodel GC
The most common entry point. You manage kitchen, bath, addition, and whole-home remodels, coordinating plumbers, electricians, drywall, and finish trades. Projects run $15,000-$200,000, the license is usually a state or county GC license, and bonding requirements are modest. Markup runs 10-20% on cost-plus or fixed-bid contracts. Startup lands in the $10,000-$40,000 range because tools are light and the bond is small. The cash-flow risk is real but bounded: a single delayed draw on a $50,000 job hurts but does not sink you if you carry reserves.
New-Construction Home Builder
The highest capital model on the residential side. You build custom or spec homes, which means larger budgets ($250,000-$1,000,000+), longer timelines, draw schedules tied to construction milestones, and a construction loan or builder's line. Bonding capacity becomes the gating question because the surety underwrites your balance sheet before backing a project. Spec building ties up your own capital in land and the structure until sale. Startup capital and working capital both run high, and a single project ties up cash for six to twelve months.
Commercial GC
The most regulated and most bond-dependent model. Public and commercial projects often require performance and payment bonds, prevailing-wage compliance, certified payroll, and stricter insurance limits. Procore-class project management is effectively required. Bonding capacity, not tools, sets the ceiling on the size of job you can bid, and that capacity grows with your track record and your audited financials. Startup costs run well past $75,000 once bonding, insurance limits, and software are factored in, but margins on a managed commercial job can be steadier than residential.
Handyman Scaling to GC
The lowest-cost on-ramp. A handyman who already owns tools, a truck, and a customer base adds a GC license to take on jobs above the handyman dollar cap and to pull permits and hire subs. Startup is mostly license, bond, and insurance because the truck and tools already exist. This is the cheapest path to a license, often under $10,000, and it lets you grow project size and markup as your bond capacity and reputation build.
What Most People Forget
Hidden costs that catch first-time general contractors off guard.
Surety Bonding Capacity Is the Real Ceiling (limits job size, not just a fee)
A surety bond is not insurance you buy off a shelf. The surety underwrites your credit, your experience, and your working capital before it backs a project, and your single-project and aggregate bonding capacity cap the size and number of jobs you can run at once. New GCs often get approved for $250,000-$500,000 in aggregate capacity and grow from there. Thin financials or a soured project can shrink your capacity overnight and lock you out of bigger work. Build the relationship with a surety agent early.
Workers Comp Is Priced by Trade Code ($2-$30+ per $100 of payroll)
Comp rates swing wildly by the trade classification on the payroll. Clerical and estimating payroll prices near the floor; roofing and structural work prices many times higher. Misclassifying payroll or letting an uninsured sub work under you triggers a brutal audit bill at year end when the carrier reclasses the exposure. Collect a current certificate of insurance from every subcontractor before they set foot on the site.
Retainage Withheld From Every Draw (5-10% held until completion)
Owners and general contractors above you withhold a percentage of each progress payment, commonly 5-10%, until the project is complete and signed off. On a $100,000 job that is $5,000-$10,000 of your money sitting in escrow for months. You still owe subs and suppliers in full, so retainage is a permanent working-capital drag you have to finance until final payment releases it.
Draw-Schedule Cash Gaps (pay subs before the owner pays you)
Construction runs on progress draws tied to milestones, but you pay subs and material bills on their schedule, not the owner's. The gap between writing a sub's check and the owner's draw clearing your account can run weeks, and it compounds when multiple jobs draw at once. This timing mismatch, not the markup, is what strands undercapitalized GCs mid-project. A line of credit and supplier net-30 terms bridge it.
Permit and Inspection Delays (days to weeks of idle cost)
Permits take days to weeks to issue, and a failed inspection stops the job until the re-inspection clears. Every idle day still burns your fixed costs and pushes the schedule, and a delayed inspection can leave a crew or a sub standing around on your dime. Build permit and inspection timelines into the bid and the schedule, and never let a sub start work that an inspection has to pass first.
Lien Law Compliance (preliminary notices and lien waivers)
Mechanic's lien law protects you when an owner does not pay, but only if you file preliminary notices on time and collect signed lien waivers from every sub and supplier you pay. Miss a deadline and you lose your lien rights; skip collecting waivers and a paid sub's unpaid supplier can lien the owner's property and come back on you. The paperwork is unglamorous and the deadlines are unforgiving. Many GCs use software or a service to track notice and waiver deadlines on every job.
Self-Employment Taxes (15.3% of net earnings)
15.3% of net earnings for Social Security and Medicare on top of income tax (IRS, 2026). Set aside 25-30% of every dollar of profit, and remember that paying subs as 1099 contractors shifts their payroll tax to them but does not touch your own self-employment tax on the markup you keep.
How Long Does It Take?
Plan for 8 to 20 weeks.
Licensing & Setup (3-10 weeks): Document your qualifying experience, study for and pass the trade and law-and-business exams, file the LLC, and submit the license application. In states with experience requirements and exam scheduling, this step gates everything and takes the longest.
Bond, Insurance & Accounts (2-4 weeks): Secure the license bond, bind general liability and workers comp, open builder's accounts at suppliers, and line up a line of credit. Start the surety relationship now if you plan to chase bonded work.
Tools, Software & Marketing (2-4 weeks): Buy or outfit the truck and trailer, set up estimating and project-management software, build the Google Business Profile and portfolio site, and finalize your contract templates.
First Projects (Months 2-6): Land your first jobs through referrals and your network, manage them tightly to protect margin, and build the reviews and track record that grow your bonding capacity and project size.
How Long Until You're Profitable?
Most general contracting business owners reach profitability within 6 to 18 months.
A general contracting business with $10,000-$75,000 in startup costs typically reaches monthly breakeven within 6-18 months. The constraint is rarely demand and almost always cash flow and margin discipline. A GC who marks up 15% on a $50,000 remodel books $7,500 of gross margin, but that margin only becomes profit after you survive the draw gaps, fund retainage, and absorb the one job that goes sideways. Profitability comes faster for handyman-to-GC operators who already own the truck and tools and slower for new-construction builders whose capital is tied up in long projects.
Typical Breakeven Timeline
| Period | Stage | Revenue vs. Costs |
|---|---|---|
| Months 1-3 | Licensing, first bids & first job | Operating at a loss |
| Months 3-6 | Two to three jobs running | Still in the red |
| Months 6-12 | Steady pipeline & repeat clients | Approaching breakeven |
| Months 12-18 | Larger jobs, growing bond capacity | At or near breakeven |
| Months 18+ | Crew and volume growth | Generating profit |
Most general contracting business owners break even within 6-18 months, faster for handyman-to-GC operators and slower for new-construction builders.
First-Year Cash Flow Summary
| Category | Low | High |
|---|---|---|
| One-Time Startup Costs | $10,000 | $75,000 |
| 12 Months Operating Costs | $8,400 | $54,000 |
| Total First Year | $18,400 | $129,000 |
How to Start for Less
Scale Up From a Handyman or Trade License (Save $10,000-$30,000)
If you already own a truck, tools, and a client base from handyman or specialty-trade work, adding a GC license costs mostly bond and insurance. You skip the largest one-time outlays and grow project size as your bond capacity builds.
Start With Cost-Plus Contracts and Small Remodels (Protects margin, frees capital)
Cost-plus billing passes material and sub costs straight through with a transparent markup, so you carry less risk than a fixed-bid that can underprice a surprise. Smaller remodels mean smaller draw gaps and smaller retainage holds, which keeps your working-capital need low while you learn the cash-flow rhythm.
Rent the Rare Tool Instead of Buying It (Save $3,000-$15,000)
A GC needs a reliable truck and a core kit, not a full trade shop, because subs bring their own equipment. Rent the concrete saw, the lift, or the specialty tool you touch twice a year and put the saved capital into reserves.
Use Supplier Net-30 and a Line of Credit (Bridges the draw gap)
Builder's accounts at the lumber yard and supply houses extend net-30 terms that float material costs until the owner's draw clears. Pair that with a modest line of credit and you finance the gap between paying subs and getting paid without burning your own cash.
Run Estimating in QuickBooks Plus a Takeoff Tool First (Save $1,200-$4,000/year)
You do not need a full Procore or Buildertrend subscription for your first handful of residential jobs. QuickBooks for the books plus a basic takeoff tool and a shared schedule covers a solo GC until job volume justifies the upgrade.

Comparing Startup Costs
- Handyman Business - Lower startup cost and the most common on-ramp to general contracting. Handymen handle the small jobs below a GC's threshold, and adding a GC license lets them take on permitted, sub-coordinated work.
- Painting Business - A specialty trade a GC subs out on nearly every job. Lower startup cost and a common first business for someone who later moves into general contracting.
- Roofing Business - A high-risk specialty trade with steeper insurance and comp rates. Many GCs started in a single trade like roofing before broadening into project management.
- Concrete Business - A foundation-and-flatwork trade a GC coordinates on new construction. Similar construction-and-trades cost range with more owned equipment.
- Electrician Business - A licensed trade a GC hires on every permitted job. Higher licensing barrier and a steadier sub relationship for the contractors who use them.
- Plumbing Business - Another licensed trade central to any remodel or build. A GC's most-used subcontractor alongside the electrician, with its own license and bond path.
Frequently Asked Questions
How much does it cost to start a general contracting business?
Startup costs range from $10,000 to $75,000. The low end is a handyman-turned-GC with a license, a license bond, general liability, a used truck, and supplier accounts. The high end is a residential remodel or new-construction GC carrying a larger bond, workers comp for a crew, a second truck and trailer, estimating and project-management software, and the working capital to pay subs before the first draw clears. Commercial GCs carrying performance bonds run higher still.
How much do general contractors make?
A general contractor earns a markup on the job, typically 10-20% of project cost on cost-plus or fixed-bid contracts. Solo residential GCs commonly net $60,000-$120,000 a year; established owners running multiple jobs and a crew earn $100,000-$250,000+ (Bureau of Labor Statistics, 2025). Income tracks job volume, markup discipline, and how well you manage the cash-flow gap between paying subs and collecting draws.
Is a general contracting business profitable?
Yes. Well-run GCs net 10-25% on managed projects once established. Profit depends less on demand than on margin discipline and cash flow: protecting your markup against surprises, financing retainage and draw gaps, and never letting one bad project drain the reserves. Markup, not labor hours, is where a GC makes money.
Do I need a license and bond for a general contracting business?
In most states, yes. A general contractor or B license is required to pull permits and contract above a dollar threshold, and the path usually runs trade and law-and-business exams plus documented experience. A license or surety bond is required alongside it, often $15,000-$25,000 of coverage, for which you pay an annual premium of 1-5%. Commercial and public work adds performance and payment bonds underwritten against your financials. Check your state's contractor board before you bid.
What software do general contractors use?
Residential remodelers and custom builders lean on Buildertrend or CoConstruct ($99-$399 a month) for estimating, scheduling, client portals, and selections. Commercial and larger GCs use Procore, priced on construction volume. A solo GC can start with QuickBooks for job-cost accounting plus a basic takeoff tool and a shared schedule, then upgrade to a full platform once job volume justifies it.
How long does it take to start a general contracting business?
Plan for 8-20 weeks from decision to first project. The timeline depends on documenting qualifying experience, passing the trade and law-and-business exams, securing the license bond and insurance, and landing your first jobs. States with experience requirements and scheduled exams take the longest, so start the licensing process before anything else.
