Miami Appraisal Is A Single Family House With A Separate Guest House Considered A Multifamily In Miami Florida?

Is a single family house with a separate guest house considered a multifamily in miami florida? - miami appraisal

I have a house in Miami, Florida, which is assessed as if it were a multi-family. However, it is actually a single family with a house outside a guest room with bath. I wonder if it was a mistake because of the changing views of the assessment on-line tools and the nature of the family at home and then the new price is about 30% higher.
