Re: Minor offenses

I assume you are asking about "the age of consent".

It is 18 with less than 3 years age difference.California:

The age of consent is 18, with a misdemeanor if the minor has 3 or fewer years of difference with the major. Penalties increase if the minor is under 14 and the major is above 21.
