Do You Need a Permit for Pressure Washing? in Verenigde Staten
Rarely. Residential pressure washing of driveways, siding, decks, and patios does not require a building permit in the vast majority of jurisdictions. However, wastewater discharge regulations may apply — some municipalities require runoff capture to prevent contaminated water from entering storm drains. Commercial pressure washing is more heavily regulated and may require a business license and compliance with Clean Water Act provisions.

Country-specific detail
In the US, residential pressure washing does not require a building permit. The work is classified as exterior cleaning and maintenance, which falls outside the scope of the International Building Code and International Residential Code. However, the Clean Water Act and the National Pollutant Discharge Elimination System (NPDES) regulate the discharge of wash water into storm drains. Many municipalities — particularly in California, Florida, and the Pacific Northwest — require that pressure washing runoff be captured, filtered, or directed to sanitary sewer systems rather than storm drains. Commercial pressure washing businesses typically need a general business license and may require an NPDES stormwater permit. Some HOAs restrict pressure washing hours and equipment noise levels. Pressure washing historic masonry may violate local preservation ordinances if it damages the surface.
