Since they require you to have a California )CA) address, and if you provide a CA address for an employer, you may have to file a CA return next year as a resident. It's not clear why any employer would require you to provide an address where you do not live.
Currently, in CA, the rule is, if a nonresident receives W-2 wages for work performed out of state, even if it's from a California employer, the income is not subject to California income taxes. This means if you do not perform your work within the state of CA, then your income should not be taxed to CA. However, this employer is requiring a CA address which will likely complicate things for you.
