How to Start a Construction Company Step by Step

Starting a construction company is not a to-do list you can attack in any order — it is a dependency chain where each step unlocks the next. You cannot bind insurance without a registered entity, cannot pull most licenses without proof of insurance, and cannot open supplier credit without all three. Contractors who launch clean do it in a fixed sequence and run the slow parts in parallel with the fast ones. Here is that sequence, in the order that actually works, with the timing and the gates that decide it.

Step 1: Form the entity and get the EIN (week 1)

Nothing else can start until this exists. File articles of organization for an LLC with your secretary of state ($50 to $500 depending on the state), then apply for an EIN on irs.gov — it is free, takes about ten minutes, and every downstream step demands it. The LLC matters more in construction than in most trades because a structural defect or an injury on your site is exactly the claim that reaches for your house; the entity is the wall between the business and your personal assets, but only if you run it as a separate company.

The moment the EIN lands, open a dedicated business bank account (Chase Business Complete, Bluevine, or a local bank that knows contractors) and a business credit card. Do this before any money moves. Commingling funds is the single easiest way for a plaintiff’s attorney to pierce the LLC and reach you personally.

Step 2: File the contractor license and bond immediately (week 1, in parallel)

The license is the slowest step, so you start it the same week as the entity, not after. Requirements swing hard by state — some need years of documented experience and two exams, others just a city registration.

Order your license bond at the same time — a contractor bond typically runs $10,000 to $25,000 in coverage and costs roughly $100 to $400 a year — because the license application usually requires it. Book your exam date through PSI or Pearson VUE early; seats fill weeks out in busy states, and the licensing clock does not start until your file is complete.

Step 3: Bind insurance the week your entity clears (weeks 2 to 3)

With the entity and bank account live, bind coverage — and you need it before the license approves anyway, since most applications require the certificate. The core stack for a general contractor:

• General liability: $1M per occurrence / $2M aggregate is the market standard GCs, GCs’ clients, and permit offices expect. Roughly $1,200 to $6,000 a year depending on scope and revenue.
• Workers compensation: required in nearly every state the day you have one employee. Construction class codes are mid-to-high risk, commonly $5 to $15 per $100 of payroll depending on trade.
• Commercial auto: on the work truck, about $1,500 to $3,500 a year.
• Builder’s risk / tools: per-project coverage for the structure under construction and your equipment.

Pick your agent like a subcontractor, not a vendor. Construction runs on certificates of insurance — every GC you sub for, every supplier credit line, every commercial bid wants a COI naming them, often same-day. An agent who issues certificates within hours is worth a slightly higher premium.

Step 4: Open supplier accounts and set up the back office (week 3 to 4)

Once you are licensed and insured, take the certificate package to your suppliers and open net-30 trade credit at more than one. For a general contractor that means the lumberyards, a supplier like ABC Supply or Beacon for envelope materials, and Home Depot Pro or a local building-supply house. Open at least two accounts even though you will favor one — the delivered price on an identical material list varies by hundreds of dollars per job between suppliers, and after a busy season the accounts you hold get materials allocated first.

At the same time, stand up the minimum back office: estimating and project-management software (Buildertrend or Procore for larger operations, a spreadsheet plus a contract template to start), a written contract vetted for your state’s lien and payment rules, and a bookkeeping system. This is the point where the full launch sequence and cost detail is worth reading in depth, and where you decide how you will price — markup versus margin is where new contractors lose money.

The rule: start owner-operator (or with vetted subs) until your pipeline consistently exceeds what one person can build, then hire your first employee the month you are turning work away.

Getting found is the part that decides everything

You can complete every step above and still sit idle if the phone never rings. Two moves are free and worth doing the week you are legal.

Claim and fully complete your Google Business Profile — service area, real photos of finished work, and your first reviews — and ask every early client for a review before they leave the site. Then list yourself in the local channels where homeowners search for contractors. Those two steps pull more first calls than any ad while you are new. The broader playbook is in getting your first clients.

The higher-stakes part is your website and paid lead flow, where doing it badly costs more than not doing it. A contractor site is not a brochure — it has to load fast on a phone, rank for “contractor near me,” and turn a searching homeowner into a booked estimate.
