Taking something from someone's house without their permission is generally referred to as theft or burglary, depending on the circumstances.
Theft: Theft is the act of dishonestly taking someone else's property with the intent to permanently deprive them of it. If someone takes an item from another person's house without permission and with the intention of keeping it for themselves, it can be considered theft.
Burglary: Burglary is a specific type of theft that involves unlawfully entering a building, such as a house, with the intent to commit a crime, typically theft. So, if someone enters a person's house without permission and takes something, it can be considered burglary.
The severity of the offense and the legal consequences can vary depending on the jurisdiction, the value of the stolen items, and the circumstances surrounding the act. Both theft and burglary are illegal acts and can result in criminal charges if caught and prosecuted.
