How to Start a General Contracting Business: The Complete 2026 Roadmap

Most people who start a general contracting business already know the work. You've framed, hung drywall, run a crew, or managed jobs for someone else's company. What you're starting now is different. A general contractor doesn't get paid for swinging the hammer. You get paid for taking a messy project, pricing it right, lining up the people who do the work, and making sure the owner gets what they signed for and everybody on the job gets paid.

There's room for you. The U.S. Bureau of Labor Statistics counts about 609,100 construction manager jobs in 2025 and projects 9 percent growth through 2035, with roughly 49,700 openings a year. The BLS also says about 38 percent of construction managers are self-employed, and that people with a high school diploma and many years in a construction trade are more likely to work as self-employed general contractors. That's most of us. Nobody hands you a book of work, so you build it.

This guide walks through how to start a general contracting business in the order things happen, from the license to your first jobs and beyond. Where the rules change from state to state, I'll say so and point you to the board that decides.

1. Decide What Kind of General Contractor You'll Be

"General contractor" covers a lot of ground. Pick your lane before you spend a dollar, because it drives your license, your insurance, your bond, and who you hire.

Residential remodeling: kitchens, baths, additions, whole-house renovations. Homeowners, steady demand, and jobs a small crew can run. Most one-truck GCs start here.
Light commercial and tenant improvements: offices, retail build-outs, small restaurants. Bigger tickets, slower payment, more paperwork.
New residential construction: custom homes, spec homes, small multi-family. Big dollars, big float, and a lot of subs.
Specialty and repair: decks, outdoor structures, punch-list work, small repairs. A good way to build cash flow and a reputation while you earn bigger jobs.

The other decision is how much you self-perform. Some GCs frame and finish with their own crew and sub out only electrical, plumbing, and HVAC. Others never touch a tool. Either way, the more you sub out, the more your business is paperwork, scheduling, and cash flow. Write down the type of work, the size of job you're comfortable carrying, and the area you'll cover.

2. Check the License. This Is the Gate.

Do this before anything else, because the answer decides what you can legally bid and build.

The national picture: there is no national general contractor license. States set the rules, and in some places cities and counties do. The SBA says states tend to regulate a broader range of activities than the federal government, with construction among them, and that local governments set their own registration, licensing, and permit rules.

Your state could look like any of these:

A strict statewide license. California is the example. The Contractors State License Board requires at least four years of experience in the class you're applying for before you can sit for the exam, and someone with firsthand knowledge of your work has to verify it. A contractor there needs a license for any project worth $1,000 or more in combined labor and materials.
A statewide board with its own exams. Florida licenses general contractors through the Construction Industry Licensing Board.
No statewide license at all. Texas does not require one. Next Insurance's Texas guide notes that cities set their own rules: Dallas requires annual registration with proof of insurance, Austin requires registration, and Houston asks for a business license.

Your state will look like one of those, or something in between. I won't guess at the exact requirements, because a wrong guess here costs real money.

The common pieces

Most licensing systems are built from the same parts:

Experience, often verified by someone who saw the work.
Exams: usually a trade exam plus a business and law exam.
Proof of insurance, and in many states a license bond.
A qualifying individual who passed the exam and answers for the business.
Renewals, and in many states continuing education.
Classifications: residential vs. commercial, building vs. specialty, sometimes a cap on job size.

The NASCLA exam

The NASCLA Accredited Examination for Commercial General Building Contractors is a standard exam that participating states accept in place of their own trade exam. NASCLA's list of participating agencies is a short one that includes California, Florida, Georgia, North Carolina, Oregon, Utah, and Virginia. It helps if you plan to work in more than one state, but it's not a free pass. You still apply in each state, and many still require their own business and law exam, which NASCLA tracks on its state exams page.

How to check your state

Search "[your state] contractor license board" and open the official .gov site.
Find the general contractor classification and read the requirements for experience, exams, bond, and insurance.
Check what your city or county requires on top. Start at the SBA page above.
Ask what happens if you take a job over any dollar limit on your classification.

Guess at this and you can lose a lot: fines, invoices you can't legally collect on, and a harder application later. The startup checklist in our General Contracting Business Starter Kit has a licensing section to work through, and I'll say more about it in step 6.

3. Set Up the Business Entity

Sole proprietorship or LLC. A sole proprietorship is the simplest: you and the business are one legal person, so a lawsuit or unpaid debt can reach your house, your truck, and your savings. A general contractor carries more of that risk than most trades, because you're responsible for the whole project, including your subs' work. Most GCs form an LLC. The SBA's guide to business structures lays out the options, and your Secretary of State handles the filing. Fees vary by state.

Get an EIN. It's free from the IRS, and you can apply online. You need it for your bank account and your license application.

Register your name. If you operate under a name other than your legal one, file a DBA where your state requires it, and check that the name isn't taken. The SBA's registration guide walks through it.

One tip: in many states the license is issued to the company and a named qualifier. Sort out your entity before you file for the license, not after, so you don't have to amend it.

4. Get Insured and Bonded

Insurance and bonds are the first things clients, lenders, and license boards ask to see. They are not the same thing, and mixing them up is a common beginner mistake.

Insurance

According to Insureon, whose data comes mostly from general contractors with fewer than five employees, the 2026 averages look like this:

General liability: about $162 a month ($1,950 a year) for $1 million per occurrence and $2 million aggregate. This covers property damage and injury claims from your work, and it's the policy clients and boards ask about first.
Workers' compensation: about $196 a month. Required in most states once you have employees; it scales with payroll and the type of work.
Commercial auto: about $287 a month for a business vehicle.
Builder's risk: about $136 a month. It covers a structure while it's being built. Sometimes the owner buys it, sometimes you do, so settle that in the contract.
Business owner's policy: about $125 a month, bundling liability with property coverage.

Those are averages. Your quote depends on your state, payroll, and claims history. Get at least three.

Two things catch new GCs off guard. First, your subs' insurance is your problem too. If a sub's worker gets hurt and the sub has no workers' comp, the claim can land on you. Second, owners and commercial clients often want to be named as additional insureds. Ask your agent how that works before you bid.

Bonds

There are two kinds, and they do different jobs.

A license bond is something many states require to issue or renew your contractor license. It protects the public, and it won't cover your own losses. California, for example, requires a $25,000 contractor license bond that protects consumers harmed by defective work or violations, and employees owed unpaid wages. You don't pay the full amount; you pay a premium. NFP puts typical premiums at 1 to 3 percent of the bond for strong credit, around 3 to 5 percent for average credit, and 8 to 10 percent or more for poor credit, usually charged yearly for a license bond. Your board sets the bond amount, so your state's number could be higher or lower.

Bid, performance, and payment bonds are contract bonds. A performance bond guarantees you'll finish the job, and a payment bond guarantees your subs and suppliers get paid. Public work often requires them (the federal version is the Miller Act, and most states have their own). You probably won't need them on residential work in year one. You will if you chase public jobs.

If you can't get bonded on your own, the SBA Surety Bond Guarantee Program can help. It guarantees contract bonds for qualifying small businesses on contracts up to $9 million, or $14 million on federal work, and the SBA charges 0.6 percent of the contract price on performance and payment bond guarantees. You still have to meet the surety's credit, capacity, and character standards.

5. Set Up the Money Side

A general contractor lives and dies on cash flow, because you often pay subs and suppliers before the owner pays you.

Open a business bank account with your EIN and run every dollar through it. Mixing business and personal money wrecks your books and weakens the protection your LLC gives you.
Take a deposit before you buy anything, and check your state's rule first. California's consumer guide, for instance, tells homeowners to pay no more than 10 percent down or $1,000, whichever is less.
Tie payments to milestones, not dates. Deposit at signing, then payments at framing, rough-ins, drywall, finishes, and final. Each payment should cover work already done, so you're never financing the owner.
Understand retainage. On larger jobs the owner holds back part of each payment until the work is done. Levelset says retainage typically runs 5 to 10 percent of each progress payment, and some states cap it. You'll hold it from your subs the same way, so put the percentage and release date in writing.
Keep a cash cushion for a few weeks of costs before a job pays out.

6. Set Your Rate and Price the Job

Most GCs who fail don't fail on skill. They fail on math. You win a job at a price that doesn't cover your overhead, then slowly lose money on every project.

Start with your own rate. Figure out what you need to take home, add your overhead (insurance, truck, phone, software, bookkeeping, license fees, the hours you spend on estimates that don't win), and divide by the hours you can actually bill. That's your hourly cost. You can run quick numbers on our free general contracting calculators, including a job cost estimator that builds a total from materials, labor hours, rate, and markup.

Then price the project from the bottom up:

Labor: your crew's hours at a rate that includes payroll taxes and workers' comp.
Materials: itemized, with waste factored in.
Subcontractor quotes: at least two per trade, in writing, with the scope spelled out.
Permits, dumpsters, and other job costs.
Overhead and profit, the part new GCs leave out or guess at.
Contingency for surprises.

Markup is not margin

This trips up almost everybody. Mark a $10,000 cost up 20 percent and you charge $12,000, but your margin is about 16.7 percent. To earn a true 20 percent margin, mark up 25 percent. Decide which number you're targeting and use the right formula.

The kit that does this for you

If you'd rather start with working math than a blank spreadsheet, the General Contracting Business Starter Kit is $49, one payment, and the files are yours to keep. It includes a pricing calculator that builds a project price from your labor, materials, and subcontractor quotes with a payment schedule, an estimate and invoice spreadsheet, a change order form in Word and PDF, and a startup checklist covering licensing, bonding, subs, and lien waivers. You don't need a Bit & Grain account to use it.

7. Get the Subcontractor Paperwork Right

Subs are where a general contractor makes or loses money, and where much of the risk lives. Each electrician, plumber, framer, and painter you hire is a business you're responsible for managing. A handshake isn't enough.

What a good subcontract covers

Contractor magazine's overview of sub agreements lists the same core clauses you'll find in most templates:

Scope of work, written so two people can't read it two ways. What's included, and what isn't.
Price and payment terms. Lump sum or time and materials, how often you pay, and when. Pay-when-paid and pay-if-paid clauses are common, but how enforceable they are depends on your state.
Schedule: start and finish dates, and what happens when the job slips.
Insurance requirements: types, limits, and whether you're named as an additional insured.
Indemnification: who covers what if there's a claim. It's the most negotiated clause, and the rules differ by state.
Dispute resolution, termination, and governing law.
A change order rule: no changed work without a signed change order.
Lien rights and waivers: what the sub signs when they're paid.

Pay a construction attorney in your state to review your master subcontract once. It's cheap for a template you'll use on twenty jobs.

Your sub onboarding checklist

Before a sub touches your job or gets a check, collect:

A signed subcontract with the scope and price for this job.
A W-9. The IRS Form W-9 gives you their legal name, entity type, and tax ID for year-end 1099s.
A certificate of insurance showing general liability and workers' comp at the limits your contract requires. Check the expiration date.
A copy of their license, if your state or the job requires one.
An independent contractor check. A real sub runs their own business, brings their own tools, and has other clients. If someone works for you like an employee, they may legally be one, and misclassification can cost more than the payroll tax you tried to save.

Bit & Grain's subcontractors feature keeps each sub's contact info, rates, insurance and license expiration dates, W-9 status, and job history in one record, with alerts before a certificate lapses. It also rolls sub costs into each job's profit and loss, so you can see what a job really made.

8. Use Lien Waivers and Know Your Lien Rights

New general contractors skip this step, and it bites hardest.

What a mechanics lien is

A mechanics lien is a legal claim against a property, filed by someone who supplied labor or materials and didn't get paid. Levelset explains that anyone who furnishes labor or materials for a permanent improvement can generally file one, including general contractors, subs, and suppliers. Contractors typically have anywhere from two months to a year after finishing work to file, but notice requirements and deadlines differ by state, and missing one can cost you your lien rights.

That's your protection if an owner doesn't pay you. It's also your exposure if you don't pay a sub: they can lien the owner's property, and the owner will come looking for you.

What a lien waiver is

A lien waiver is a document where a contractor, sub, or supplier gives up the right to lien for a payment. There are four common types:

Conditional progress waiver: you release your rights for a progress payment, but only once the money clears.
Unconditional progress waiver: you release them now, whether or not the money shows up.
Conditional final and unconditional final waivers: the same two ideas, for the last payment.

The rule of thumb: sign conditional waivers when you submit your invoice, and sign unconditional waivers only after the payment has cleared your bank. An unconditional waiver holds up even if you haven't been paid, as Levelset's California guide warns.

The state-by-state catch

Some states, including California and Texas, require specific statutory waiver forms, and a form that doesn't follow the statute can be invalid. California won't let you waive lien rights in the contract before work begins, and Levelset's advice there is to use the exact statutory form and add no language of your own. Texas puts its rules in Chapter 53 of its Property Code. Check your state's forms and deadlines, and ask a construction attorney if you're not sure.

Make it a routine

Collect a waiver from every sub and major supplier with every payment you make them. If your state requires a preliminary notice, calendar the deadline on day one. Keep every signed waiver in the job file.

9. Tools, Truck, and Startup Costs

A general contractor needs less heavy equipment than a trade contractor, because you subcontract the specialty work. That keeps the startup cost lower, but it's still real money.

Estimates vary by source and by the work you do. ZenBusiness lists liability insurance and a surety bond at $1,500 to $5,000, state license and exam fees at $300 to $1,200, a work truck or van at $10,000 to $45,000, and basic power and hand tools at $2,000 to $8,000. Stripe puts the initial outlay for a small or multicrew construction business at roughly $15,000 to $50,000 or more. Treat both as planning figures, not quotes.

What most new GCs need:

A reliable truck. Used is fine.
A core set of power and hand tools you use every day. Rent the specialty machines until you've booked the jobs that need them.
A laptop, a phone, and a printer or scanner for plans, contracts, and signatures.
Layout tools, safety gear, and a budget for permits and plan copies.

Don't buy it all at once. Your first three jobs will tell you what you use. Keep the cash for the float between paying subs and getting paid.

10. Build Your Brand and Web Presence

Owners hire contractors they trust, and trust starts before you walk the property.

A name and logo that read well on a truck door, a yard sign, and an invoice.
A domain name, registered with a registrar like Cloudflare or Namecheap. It usually runs $10 to $20 a year.
A professional email at your domain, not a personal Gmail address.
A simple website with your services, your service area, a few project photos, and a way to request an estimate.

A plain site that loads fast beats a fancy one that never launches. If you want to see how Bit & Grain fits a GC's day, the general contracting page walks through it.

11. Set Up Your Operations System

This is where a lot of new GCs lose control. One job runs fine out of a notebook and a text thread. Five jobs at once, with two subs on each and three owners asking when the tile goes in, does not. Your operations system needs to do five things:

Estimates and invoices. Build an estimate from the job's labor and materials, send it to the owner, get approval in writing, and turn it into an invoice when the work is done. Bit & Grain's estimates and invoicing does that, and the invoice takes card payments through Stripe.
Change orders. Every scope change gets a description, a price, and an approval before the work starts. Service log and change orders tracks the approval state, so the next invoice picks up every approved adjustment and you don't argue about it at the end.
A record for every sub, with documents, rates, and expiration dates.
A schedule that shows who is on site, which trade is next, and what is waiting on an inspection.
A job file with the contract, permits, photos, receipts, and signed waivers in one place.

Bit & Grain is $29 a month with Grain AI included, and the first 30 days are free; the details are on the pricing page. With Grain AI you can ask for a job, draft an estimate, or schedule a visit by typing or talking, from your desk or once you're parked at the site. If you'd rather stay on spreadsheets for your first few jobs, the kit above works fine. Move to software when the spreadsheets start to hurt.

12. Get Your First Clients

With the license, insurance, and paperwork in place, you need the phone to ring.

Google Business Profile first. Set up a free Google Business Profile. It's how you show up when someone searches for a general contractor or remodeler near them. Add your service area, hours, services, and real photos of finished work, and keep your name, address, and phone the same everywhere you appear online.

Reviews. Owners hiring a GC for a $40,000 project read the reviews. Ask every happy client for one after final payment clears, when they're happiest. Bit & Grain's review requests send a branded email with a link to your Google Business Profile, by hand or on a schedule after the invoice is paid.

Referral channels that work for GCs:

Past clients and their neighbors. A finished project often leads to the next one on that street.
Architects, designers, and real estate agents who need someone dependable.
Your subs and suppliers. They know who's hiring and who's good.
Property managers and small commercial owners, once you're ready for their payment terms.

Show the work. Post finished projects and before-and-after photos on Facebook and Instagram. You don't need polish, just consistency. Bit & Grain's social media tools let you schedule posts next to your job workflow.

Bid with a process. Don't quote on the phone. Walk the job, write down the scope, and send a written estimate within a day or two. A fast, clear estimate does more for you than the lowest price. Your first few bids will lose. Track why.

13. Run the Jobsite Like a Pro

GCs earn their reputation on how clean the job runs.

Start with a kickoff walk-through. Confirm the scope, schedule, payment milestones, and who makes decisions. Put permits and inspections on the calendar.

Coordinate your trades. Give each sub a clear start date and what must be done before they begin. Check in the day before. A missed handoff costs a day, and a day costs money.

Change orders every time. "While you're in there, can you also..." is a change order, not a favor. Write down the scope, the price, and the schedule effect, and get a signature before the work starts. The kit's change order form works on paper, and Bit & Grain handles them in the app with an approval state both sides can see.

Keep the owner informed. Most owner complaints are communication complaints. Send a short update weekly, share photos, and tell them early when something will cost more or take longer.

Close the job. Do a punch-list walk with the owner, fix what's on it, collect the final lien waivers from every sub and supplier, send the final invoice, then ask for the review. A clean closeout turns one project into the next referral.

14. Track Your Money and Handle Taxes

You're self-employed now, which means nobody is withholding taxes for you.

Track every expense. Materials, fuel, tools, permits, insurance, sub payments, software, the phone. Every legitimate business expense lowers your taxable income, but only if it's recorded. Bit & Grain's receipt scanning lets you snap a photo of the ticket at the supply house counter, so it's logged and sorted for tax time.

Track your mileage. GCs put on a lot of miles between sites, supply houses, inspections, and estimates. The IRS sets the business rate each year: 72.5 cents per mile for the first half of 2026 and 76 cents from July 1, per the IRS standard mileage rates page. A log you keep as you go beats a guess in April, and Bit & Grain has mileage tracking built in.

Pay quarterly estimated taxes. Self-employed owners owe self-employment tax of 15.3 percent on net earnings on top of income tax, and the IRS expects quarterly payments through Form 1040-ES if you'll owe at filing time. A habit that works: move a set percentage of every payment into a tax account the day it lands. Ask a CPA what percentage fits you.

Plan for 1099s. If you pay subs as independent contractors, you'll report those payments on a 1099-NEC after year-end. The dollar threshold changed for 2026, so check the current Form 1099-NEC instructions or ask your accountant. The W-9 you collected at onboarding makes this painless.

Know your job-level numbers. Revenue minus labor, materials, and sub costs is your job margin. If a certain kind of project runs thin, you want to know by job three, not job thirty. Hire a bookkeeper or a CPA who works with contractors as soon as you can afford one.

15. Grow on Purpose

Once you're booked and profitable, grow deliberately.

Hire a lead carpenter or project coordinator before a crew of five. The first hire should free your time to sell and manage.
Build your bench of subs. Two good subs per trade means you're never stuck when one gets busy.
Raise your prices once your schedule fills. A backlog is a signal.
Move up in job size one step at a time. Each step means more float, more paperwork, and sometimes a bigger bond.
Add repeat revenue: service and warranty work for past clients.

The Bottom Line

The order matters. License first, then the entity, then insurance and bonds, then a pricing method that covers your costs, then signed paperwork and lien waivers with every sub. Do those in sequence and the first job starts on solid ground.

If you want the math and paperwork done for you, grab the General Contracting Business Starter Kit. When you're ready to run the jobs, the change orders, and the subs from one place, start free at Bit & Grain. Either way, start with your state's license board.
