George,
You might consider getting an address for your garage, basement, etc. With a seperate mailbox number, its a loophole that alot of at home businesses take advantage of, that way. That way "the business" is renting the garage from you. So the IRS sees that your LLC is renting, making deductions on upkeep, etc on the space they are renting. It's how guys have FFL's for gunsmithing out of their houses.
The pain of it though, is that you have the charge "the business" a nonimal amount each month for rent, and show it being paid. Benefit being that it's a tax write off for the business, depending on how you write it off.
