Penal Code 647e PC prohibits unlawful lodging. This is colloquially known as squatting. However, PC 647(e) also includes setting up a temporary shelter, like a tent, on property without the permission of the owner. It can even be violated when someone sleeps on another person's property. In some areas of California, illegal lodging has become a serious issue. Homelessness in many cities has grown as housing prices have increased. Enforcement of 647e PC has become controversial.
