I would like to know about the tax implications of renting out permitted space in a home. I am not sure how to claim the income. I can not depreciate the space in the home because it technically does not exist. I can not claim it on tax records as it can not be added to the square footage of the house. I checked into permitting and it can not be permitted. The space was existing when I purchased my home, I didn't add it on, but now I want to rent it out. It is not accessible from the primary residence and not counted is its total square feet.
