Homelessness describes the condition of people without a regular dwelling and is not a criminal activity. However, when you see someone doing something illegal, you should call the police. Panhandling is not illegal, but if the panhandler is aggressive and you feel threatened, call 9-1-1 and move away from the subject. You should always call 9-1-1 if you need emergency assistance from police or fire or there is a medical emergency or an immediate threat to public safety. Additionally, the Napa Police Department will take action for theft, public consumption of alcohol, trespassing, or other disruptive behavior. These offenses are typically classified as misdemeanors.
