Title 24 of the Code of Federal Regulations is a set of rules created by the government to keep people safe when they go into buildings. It tells people who build and design buildings what they need to do to make sure the building is safe for everyone who uses it, including kids like you. For example, the rules might say that a building needs to have fire alarms, sprinklers or emergency exits in case of a fire. It also tells people how to make a building energy efficient, which means it uses less energy and helps the environment. These rules are important because they help make sure that buildings are safe and efficient, which is good for everyone.
