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

It depends on where you work. Many cities and counties require a general business license, some limit what wash water can run into storm drains, and a few states and cities require a contractor or home improvement registration for work on homes. The SBA says license requirements depend on your activity and location. ProfitDrawer's pressure washing guide budgets $50 to $300 for a business license and registration and says to check local rules before your first paid job.

**Checklist from the guide:**

1. **Business license:** ask your city and county. The SBA suggests checking your state and local government websites.
2. **Business name:** register a DBA if you work under a name that is not your own, or register an LLC with your state.
3. **Wash water:** ask your city or county stormwater office what they expect, especially for water with chemicals, oil or grease. Plan for drain covers or water recovery on commercial jobs.
4. **Contractor or home improvement registration:** ask your state licensing office whether house washing counts.
5. **Insurance:** general liability covers damage to a car, window or plant. Commercial clients often ask for a certificate before you start.
6. **Tax numbers:** you may need a state sales tax permit if your state taxes cleaning services. An EIN from the IRS costs $0.

The SBA also notes that some licenses expire after a set period, so keep renewal dates in your calendar. Rules differ by place, so treat this as general information, not legal advice.
