Most parents say about 11-12 years old. But, some state laws say a child must be atleast over the age of 14 to leave the house alone or stay in the house alone. My parents respect this law. Some children leave the house at a younger or stay at home at a younger age too. But, if you want to leave the house alone you must be back before dark (law). If you want to stay at home...the minimum age would be 11 through about 12. Thirteen and fourteen year olds are more capable of controling their actions. No offense to any younger kids. There are very few states in the U.S. with legal minimum ages for children home alone, but many state agencies have published guidelines. Georgia, Illiniois, Maryland and Oregon are a few of the states with specific ages mentioned in their laws.
12 years of age appears to be the most common recommendation. Below in Related Links is an article entitled Home Alone Children Legal Age Limits state by state comparison with references.
One guideline from a California child welfare representative suggests that 8 year olds and over can be left at home for a brief amount of time(such as just after school). The most common statement is that a child's maturity should be the determining factor and not just age.
CT does not have a legal age to stay home alone. The state guidelines suggest 12 but also state that you have to make a decision based on your child's maturity, the length of time alone and other factors.

There is currently not a law that specifies the age a child has to be to stay home alone overnight. It is left up to the parents to decide if their child is mature enough to handle it.

13 is the legal age for a child to be left alone in the US
There are no legal laws about the age a child may be left alone but a child who is left alone too young could leave the parent liable for negligence or child abuse. A general rule of thumb would be if the child can cook for him/herself or call emergency services.
