How can she do this without him claiming it as income.
Sorry, I missed that part of your question and my previous answer is probably the opposite of what you are looking for.
In that case, she would need to just sell it and gift him whatever she wants. But again, I am unsure of how Community Property laws affect things. But as a Single Member LLC, it would SEEM to be that it is 'separate' property and only she would be taxed.
