Do I need a business license to start a pressure washing business?

In most U.S. states, yes — you’ll need at least a general business license to legally operate a pressure washing company, even as a one-person operation. Requirements vary significantly by state and municipality: some only require a basic local business license and an EIN, while others require a specific contractor’s license once your annual revenue crosses a certain threshold, particularly for work tied to construction or property restoration. Beyond licensing, general liability insurance is effectively mandatory in practice, since a single accidental window break or siding strip can cost thousands of dollars in damages. Many states also regulate wastewater runoff disposal, which may require a separate environmental permit. Before taking on paying clients, check with your state’s Secretary of State website and local city hall, since operating without the required license can result in fines or an inability to collect on unpaid invoices.
