If you are doing business in more than one state, you need to make sure you are registered in each state where you are doing business.  You also need to follow the formalities required for each of the states.  I address issues associated with doing business in multiple states in my most recent YouTube video, as well as in my article at http://www.llcwizard.com/doing-business-in-multiple-states.

California in particular is known for having extra rules and fees.  If you are a Californian resident and own 25% or more of a company outside the state, it has to be registered in California, even though any reasonable person would say it isn't doing business in California.  The fact that a Californian owns a chunk of the company means the company is deemed doing business in California.  Welcome to Californa and its $850+ per year fees.

Make sure you know what you need to do for every state you do business in. And yes, owning property in a state is "doing business" in that state.
