Entity Decision
Do You Need an LLC for a Pressure Washing Business in Illinois?
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.
