Start a trade business

How to start a construction company

Pick a market you already know, then build the company around it: legal setup, licensing, insurance, bonding, working capital, and the job costing and billing systems that keep a growing contractor solvent.

To start a construction company, choose one market you know (residential remodeling, new homes, light commercial, or a specialty trade), write a business plan with real numbers, form an LLC or corporation and get an EIN, get the contractor licenses your state and city require, buy insurance, set up bonding if you will bid public or larger private work, and line up enough working capital to carry payroll until customers pay. Set up job costing and billing before the first job. Most young construction companies that fail do so from cash flow and pricing, not from bad workmanship.

Start with the market, not the logo

Construction is not one business. A remodeler sells to homeowners, takes deposits, and manages selections and change requests. A custom home builder works with lenders and draw schedules. A commercial contractor bids against plans, bills monthly pay applications, and lives with retainage. A specialty trade sells labor and installed material to general contractors. Each has different customers, contracts, licenses, and cash cycles.

The safest start is the market where you already have experience and relationships. A project manager who ran tenant improvements for a GC has a head start on light commercial work. A lead carpenter who built kitchens for a remodeler has one on residential remodeling. Write down the three to five customers who would hire you in the first six months. If you cannot name them, sales is your first problem.

Step by step: setting up the company

  1. Write the plan. The U.S. Small Business Administration describes a traditional plan (executive summary, company description, market analysis, organization and management, service line, marketing and sales, funding request, financial projections) and a short lean startup plan. Lenders and sureties want the traditional one. See how to write a construction business plan.
  2. Choose a structure and register. The U.S. Small Business Administration lists sole proprietorships, partnerships, LLCs, corporations, and other forms, each with different liability and tax treatment. LLCs and corporations register with the state and need a registered agent. The agency says registration typically costs less than $300, depending on state and structure.
  3. Get an EIN. The IRS issues it free online. Register the entity with the state first.
  4. Get licensed. Most states license some or all construction work, often by trade, by project size, or both, and many cities add their own registration. Start at contractor license requirements by state.
  5. Buy insurance. The U.S. Small Business Administration says businesses with employees must carry workers' compensation, unemployment, and disability insurance. General liability is the policy every customer will ask to see on a certificate of insurance. Add commercial auto and equipment coverage as needed. See workers' compensation for contractors explained.
  6. Open a business bank account and a credit line. Keep business money separate from day one. A line of credit set up while things are calm is easier to get than one requested during a cash crunch.
  7. Set up bonding if you need it. Public owners usually require bid, performance, and payment bonds. The U.S. Small Business Administration's Surety Bond Guarantee program supports small businesses that might not meet other sureties' criteria, on contracts up to $9 million for non-federal work and $14 million for federal work.

Startup cost categories

A remodeler working from a truck and a home office needs far less than a commercial contractor with a yard, a superintendent, and equipment. Plan by category and get real quotes. Working capital is the line most new owners underestimate.

Systems to set up before the first job

  • Job costing. Every cost coded to a job and a cost code, compared with the estimate weekly. See how to set up job costing for a construction company.
  • Estimating. A consistent method with burdened labor rates, overhead, and margin.
  • Billing. Deposits and payment schedules for residential work, or progress billing with retainage for commercial.
  • Change orders. Written and priced before the extra work starts.
  • Subcontractor paperwork. Subcontracts, insurance certificates, and lien waivers for every sub you hire.
  • Document retention. Contracts, plans, daily logs, and photos stored by job.

Your first year of work

Take jobs you can finish well, at a margin that covers overhead. A first-year company has no backlog to absorb a losing job. Smaller jobs with fast payment terms build cash and references. Track every job's estimated and actual costs so your second year's bids are built on your own numbers. The guide on how to decide which construction jobs to bid has a simple filter.

Hire slower than you want to. The first employee after the owner is usually a lead carpenter or foreman who can run a job without supervision, followed by part-time bookkeeping help. Owners who keep doing estimating, field work, billing, and payroll themselves hit a ceiling fast, and the billing is usually what slips first. Know which tasks you will hand off and when, and write that into the plan. See when to hire an office manager for a construction company.

Mistakes new construction companies make

  1. Taking every job offered, including ones outside your experience or license.
  2. Pricing from competitors instead of your own costs, overhead, and margin.
  3. Starting extra work without a signed change order.
  4. Mixing personal and business money, which makes taxes, bonding, and lending harder.
  5. Growing revenue faster than working capital, so the company is busy but broke.
  6. Skipping insurance certificates and lien waivers from subs.

Frequently asked questions

How much money do I need to start a construction company?

It depends on your market and trade. Plan for registration, licensing, insurance, tools and vehicles, and enough working capital to cover payroll, materials, and subs until customers pay. Get real quotes for each category.

Do I need a license to start a construction company?

In most states, yes, for at least some types or sizes of work, and many cities add local registration. Check your state's licensing board and local building department before you bid.

Should a construction company be an LLC or a corporation?

Both limit personal liability when set up and run properly, and they are taxed differently. Talk to an accountant and attorney about your situation before choosing.

When does a construction company need bonding?

Public owners usually require bid, performance, and payment bonds, and some private owners do too. Bonding capacity depends on your financial statements, experience, and character, so start the relationship with a surety agent early.

What software does a new construction company need?

At minimum, accounting plus a system for estimating, job costing, billing, and change orders. Choose one that can grow into pay apps, WIP reports, and subcontractor compliance as you take larger work.
