Previous owner didn't pull permits for enclosure, now I'm selling

[Kurt Traynor]

I purchased my current home about 2 years ago, it was a Short Sale.  One of the previous owners enclosed the back porch and the garage.  All the work seems legit but my problem is this.  Tax records in Manatee County, Florida show my house as a 2,712 SqFt Living Area, but if you add in the "additions" it would be 3,323 SqFt.  I'm inquiring about this because I'm going to put my house up for sale and want to list it at 3,323.  When will the flags come up?  I wouldn't mind biting the bullet and pulling permits and paying for them so that my tax records show the increased square footage.  The X Factor is did they do it up to code?   And if they did, are they up to today's code?  I understand my taxes will increase, but honestly, since I'm selling soon, it's not that big of a deal.

If I leave it as is, will there be a potential problem for the new buyer?  I would hate to have these skeletons come out of the closet at the 11th hour.

My realtor suggested that I call the county and discuss with them, without giving my home address so that I can get some answers.   Basically, comp's are about $135SqFoot selling right now so getting that increase on the tax records could be a difference of about $75k
