Required State License(s):

While Mobile Pressure Washing units don't need a business license to be recognized as a pressure washer, the activity of pressure washing usually requires a wastewater discharge permit from the Department of Environmental Quality or the local wastewater treatment plant depending upon the destination of the wastewater discharge.

For a better understanding of permits and licenses associated with wastewater disposal, which will depend upon your chosen wastewater destination, refer to: http://www.deq.state.mi.us/documents/deq-ead-tas-powrwash.pdf and for follow-up questions contact the Department of Environmental Quality at (800) 662-9278.
