This is the example that I believe applies to you (unless I misunderstand your initial post...that you live and work in CA.). It does not matter where your company headquarters are located or where your paycheck comes from.

Example 2 – In December 2012, you moved to California
on an indefinite job assignment. You rented an apartment
in California and continued to live in the apartment. You
retained your home and bank account in Illinois until April
2013, at which time you sold your home and transferred
your bank account to California.
Determination: Your assignment in California was for an
indefinite period; therefore, your stay in California was
not of a temporary or transitory nature. Although you kept
ties in Illinois until April 2013, you became a California
resident upon entering the state in December 2012. As a
resident, you are taxed on your income from all sources.
