Ohana Dwelling Unit - P&Z code

[Kelena]

So let's say you have a 1500 square foot house, and above you have a 500 square foot studio (on the second floor) that is accessed independently (outside stairway). The land is zoned agricultural. There is sink to make drinks but no cooking surfaces. What have I created? An ohana? A guesthouse....or an addition that will need to be torn down at great expense.
