Want to get your contractor’s license in Illinois but not sure where to start?

Why Do I Need to Become Licensed in Illinois?

Getting a “stamp of approval” is good practice and the law. Most cities and counties in Illinois require contractors to carry licenses before they can do work, but it depends on where you live. If you’re unsure, check with your local municipal department first.

So you want to obey the law. But, there are a lot of other good reasons to get a license too. Here are a few:

  • You’ll score jobs that pay more. Chances are, you can handle smaller projects, like painting trims, installing appliances, and caulking bathrooms. But a license opens the doors to bigger, more complicated jobs… and higher pay.
  • You’ll appear credible and professional. Getting a license is a great way for new customers to find you. You’ll appear in online lists with other licensed contractors. And, your license will make you appear trustworthy, safe, and credible.
  • You’ll protect your business in big ways. What would you do if your equipment got damaged or if an employee got injured? Fortunately, most licenses require you to get business insurance, like general liability insurance and workers’ compensation. These plans protect you if there’s an unexpected loss.

Think getting a contractor’s license is a good idea? We do! Now, here are the steps you need to take to get one.
