Graffiti is a form of vandalism that damages property, causes public safety issues and can result in liability. It negatively impacts local neighbourhoods by making public spaces appear unsafe. More often than not, graffiti is also used as a means to mark territories.

Commonly used graffiti materials – such as aerosol sprays – can damage the environment. They can emit 'volatile organic compounds' (VOCs), which are known to the Environmental Protection Agency as organic pollutants that can contribute to ozone levels.

One key difference between graffiti art and street art is the level of legality. Graffiti art is often done without permission and is therefore illegal, while street art can be done legally with the permission of property owners or as part of a community art project.
