How to start a construction company

From your first business plan to your first signed contract: the licensing, insurance, money and people decisions that set a new contractor up to last.

In shortTo start a construction company, choose your niche and service area, write a business plan with startup costs and pricing, form a legal entity and get an EIN, obtain the contractor licenses your state and city require, buy general liability and workers’ compensation insurance, get bonded if your work or clients require it, set up accounting and job costing, buy or lease equipment, hire and train a crew, and start bidding on jobs. Licensing, insurance and bonding rules vary widely by state and trade, so check them before you take your first job.

Step 1: Choose your niche and market

“Construction” covers very different businesses. A residential remodeler, a commercial concrete subcontractor and a general contractor building custom homes need different licenses, equipment, insurance and clients. Most successful new companies start narrow, in a trade or project type where the owner already has hands-on experience.

Common construction business types
Type Typical clients Startup notes
Residential remodeling Homeowners Lower equipment cost; strong need for sales and customer communication
Specialty trade (roofing, concrete, framing, drywall, painting) General contractors, homeowners Skilled crew and trade-specific licensing in many states
General contractor (residential) Homeowners, developers Manages subcontractors; licensing and bonding often required
General contractor (commercial) Businesses, property owners, public agencies Higher bonding, insurance and cash flow demands
Site work and excavation Developers, GCs, municipalities Heavy equipment investment
Handyman and small repairs Homeowners, property managers Lowest startup cost; check job-size limits for unlicensed work in your state

Our guide to types of construction jobs describes the roles and trades in more detail.

Step 2: Write a business plan

A construction business plan does not need to be long, but it should answer these questions in numbers:

Cash flow deserves special attention. Construction companies often pay for labor and materials weeks before a client pays, and some contracts hold back retainage until the job is finished. Plan for that gap. Our construction profit margin guide explains how margins work in the trade.

Step 3: Estimate your startup costs

Typical startup cost categories
Category Examples
Legal and licensing Entity formation, contractor license applications, exam fees, local permits
Insurance and bonds General liability, workers’ compensation, commercial auto, tools and equipment coverage, license or surety bonds
Vehicles Work truck, trailer
Tools and equipment Hand and power tools, ladders, scaffolding, safety gear; rent heavy equipment at first
Office and software Estimating, accounting, scheduling and time tracking tools, phone, computer
Marketing Website, business cards, truck lettering, online listings
Working capital Several months of payroll, materials and overhead before receivables come in

Actual amounts vary enormously by trade and region, so price each line yourself rather than relying on a national average. Leasing or renting equipment is a common way to preserve cash in the first year.

Step 4: Form your business and get an EIN

Many contractors form an LLC or a corporation to separate business and personal finances. The right structure depends on liability, taxes and growth plans, so talk to an accountant or attorney. Then:

  1. Register your business name and entity with your state (see our guide to articles of organization for LLCs).
  2. Get an Employer Identification Number from the IRS (see how to apply for an EIN).
  3. Register for state taxes, including sales tax where it applies to your work and state payroll taxes once you have employees.
  4. Open a separate business bank account and credit line.
  5. Get any city or county business license your location requires.

Our legal requirements checklist covers the general steps for any small business.

Step 5: Get licensed

Contractor licensing is set by states and, in many places, by cities and counties too. Depending on where you work, you may need:

Requirements often depend on the type of work and the size of the job. Some states allow small jobs without a license, but the thresholds differ. Check with your state licensing board and local building department before you bid, because unlicensed work can affect your ability to collect payment and may carry penalties.

Step 6: Insurance and bonding

Coverage new contractors commonly need
Coverage What it does Notes
General liability Covers third-party injury and property damage claims Most clients and GCs ask for a certificate of insurance
Workers’ compensation Covers employee work injuries Required for employers in most states; rules vary
Commercial auto Covers business vehicles Personal auto policies may exclude business use
Tools and equipment (inland marine) Covers tools and equipment on job sites and in transit Useful once you own costly equipment
Builder’s risk Covers a building under construction Often required on new builds
License or permit bond Guarantees you follow licensing rules Required for licensing in some states and cities
Bid, performance and payment bonds Guarantee you will sign, finish and pay for the job Common on public and large commercial projects

Federal construction contracts above a set dollar threshold require performance and payment bonds under the Miller Act, and many states have similar rules for public work. Our construction insurance guide goes deeper on each policy.

Step 7: Set up accounting and job costing

Many construction companies that fail were busy, not idle. They simply did not know which jobs made money. Set up job costing from day one:

A mobile time clock that records hours by job site makes job costing much easier than paper timesheets.

Step 8: Price your work

Good estimates add up direct costs and then add overhead and profit. A simple structure:

  1. Materials from takeoffs, with a waste factor.
  2. Labor as hours times a fully loaded rate that includes payroll taxes, workers’ compensation and benefits.
  3. Equipment owned or rented for the job.
  4. Subcontractors based on written quotes.
  5. Overhead share for office, insurance, vehicles and your own salary.
  6. Profit margin on top.

Step 9: Hire and manage your crew

When you hire, you take on employer duties. Key ones include:

Common mistakes new contractors make

Frequently asked questions

Do I need a license to start a construction company?

In most states, yes, at least for certain types or sizes of work. Licensing is set by states and often by cities and counties as well, and trade work such as electrical and plumbing usually requires its own license. Check with your state licensing board and local building department.

How much does it cost to start a construction company?

It depends on your trade, location and equipment. A small remodeling or specialty trade business can start with a truck, tools, insurance and licensing, while heavy civil or commercial work requires much more equipment and working capital. Build your own startup budget line by line.

What insurance does a new construction company need?

Most need general liability, workers’ compensation once they have employees, and commercial auto. Many also need tools and equipment coverage, builder’s risk and surety bonds, depending on the work and client requirements.

Should a construction company be an LLC?

Many contractors choose an LLC or corporation to separate business and personal finances. The best choice depends on liability, taxes and growth plans, so consult an accountant or attorney.

How do new contractors find work?

Through personal networks, subcontracting for established general contractors, online listings and reviews, referrals from suppliers and real estate professionals, and, over time, bidding on public projects.

Can I hire subcontractors instead of employees?

Yes, but whether a worker is truly an independent contractor depends on the actual relationship under federal and state tests. Misclassifying employees as contractors can lead to back wages, taxes and penalties.
