The four layers to check
- State business registration
LLC or DBA filing with the secretary of state (or county clerk for some DBAs).
- Contractor licensing
Some states license work above a job value or when it prepares surfaces for coatings. California: $1,000 threshold, and a C-61/D-38 Sand and Water Blasting classification.
- Local business license
Cities and counties issue general business licenses or tax receipts; check both where you are based and where you work.
- Sales tax
Some states tax cleaning services. Texas taxes pressure washing buildings, sidewalks and parking lots as building or grounds cleaning.

Wash water and storm drains
Municipal separate storm sewer (MS4) operators must hold EPA or state NPDES permits and run stormwater programs to minimize pollutant discharges, so many cities restrict what can enter storm drains - including wash water with detergents or chlorine. Ask your city’s stormwater or public works department what it requires (diverting to landscaping, vacuum recovery or discharge to sanitary sewer with permission).
Informational only, not legal advice. Rules change - confirm with the agency linked on each state page.

Frequently asked questions
Do you need a license to pressure wash?
Usually not a washing-specific state license, but you may need business registration, a local business license, a sales tax permit, and in some states a contractor license above a job-value threshold.
Do I need a permit to pressure wash?
Not typically a permit per job, but local stormwater rules can govern where wash water goes, and commercial sites may require documented practices.
Do I need a license to pressure wash in California?
A CSLB contractor license is required for projects of $1,000 or more (labor and materials), or if you employ workers or the work needs a permit. See the California page.
