  1. general contracting license in Illinois: do you need one?

    A general contractor license is required in most states above a project threshold, typically involving an exam, proof of experience, a bond, and financial statements. In Illinois, the state board or agency that handles general contracting licensing is linked below — check it, and your city or county business-license office, before you advertise or take a job. If Illinois doesn't license general contracting work at the state level, a local business license (and often liability insurance) is still expected.

  2. What it costs to start a general contracting business in Illinois

    Plan for $5,000–$25,000 (licensing, bond, insurance, software) plus working capital to get operational. On top of that: about $150 to form an Illinois LLC, then an annual report is due (~$75), a free EIN from the IRS, and general liability insurance — a few hundred dollars a year for most solo operators, plus a surety bond.

  4. Form the business in Illinois

    You can operate as a sole proprietor with no filing, or form an LLC for liability protection — for hands-on general contracting work most owners choose the LLC. The Illinois LLC filing fee is about $150 and formation takes 7–10 business days online. Then get a free EIN, open a business bank account, and register for Illinois sales tax if you'll sell taxable goods or services.

  5. What to charge for general contracting in Illinois

    Cost-plus (10–20% over trade and material cost) or fixed-price bid with a contingency. Draw schedule tied to milestones. Design-build and consulting/pre-construction fees are additional revenue. Check what the established general contracting businesses in your city actually charge before you set your rates — pricing to undercut them is the fastest way to work the first year at a loss.

  6. Getting your first general contracting customers in Illinois

    Architect and designer referrals, past clients, and a portfolio of completed projects. Reputation and a reliable sub network are the assets. Design-build and repeat clients reduce the sales grind. Tied to the housing market and interest rates — remodels hold up better than new builds in a downturn. Repeat clients, architect referrals, and a portfolio reduce the bidding treadmill.

  7. The mistake most first-year general contracting owners make

    Under-capitalizing the gap between paying subs and getting paid by the client. You often front materials and the first week of labor before the first draw clears — a job that's profitable on paper can still bankrupt you on cash flow.
