A client lives in CA and considers it his primary home (domicile). He has primary house, job, votes, dmv, etc.

They have a 2nd home in Virginia to stay while visiting family.  It is possible that in some years, they may stay more than 183 (non-consecutive) days However, they do not expect to earn any income in VA.

Does a return need to be filed in VA (if they stay more than 183 days)?  If so how is that reported on CA/VA returns?   Part year resident for each doesn't seem right if they aren't moving.
