Market Overview
Is Illinois a Good State for a Pressure Washing Business?
Illinois has no publication requirement and a moderate $75 annual fee. Chicago's 9-million-person metro area creates enormous demand for every service category — from handyman to digital marketing to food service. The $150 filing fee recently dropped significantly, making Illinois more competitive.
For Pressure Washing specifically, Illinois offers a competitive market with defined seasonal demand. With Chicago, Aurora, and Joliet as major population centers, there is consistent demand across the Midwest.

Entity Decision
Do You Need an LLC to Run It?
You are not legally required to form an LLC. You can operate as a sole proprietor from day one. Most Pressure Washing owners form one for one reason: Equipment and property damage liability — improper technique can strip paint, crack concrete, and damage siding. One job gone wrong can cost tens of thousands in damages without LLC protection.
As a sole proprietor, personal assets — savings, car, home — are directly exposed to any lawsuit or debt. An LLC creates a legal wall between you and your business.

Using your home address as your registered agent address
