Yes. Except for active duty military pay, CA (like other states) can tax you as a non-resident for any California-source income. For example, income you earned by physically working in CA, or rental income from a property located in CA.
Your state of residence can also tax your out-of-state income, but normally you can take a credit on your home state return for taxes paid to a non-resident state.
