15 years old. State has many restrictions regarding hours and duties 15 year olds can perform and work. They can't work before 7am or after 7pm. only 18 hours a week when school is in session, etc.
It's a good "starting" kind of job, so the lowest legal working age in the state is what is required.
Probably 15. Just go in and ask. Makes a good impression if you meet manager in person before applying anyway.
