Yes the sq footage can be included in the total sq footage of the house, but when it comes to appraisals and in the eye of the buyer it will not be as valuable of space as the main part of the house, so be sure to keep that in mind.... more
The answer is yes it can be included. But if it did not have a permit and does not show up on the county assessors site, you will need to reveal that in the agent notes and/or in the listing and in the Seller Disclosure Statement.
Please let me know if I can help.
