The area marked on the house book represents the occupied area, and the tenant does not have to pay rent. Just like a nearby building with five or six floors (public property), the small courtyard on the first floor does not have to pay rent. But the lessee has absolute right to use it. It is not surprising that this exists in many places outside Little Haiti. If your yard is clearly marked in the room book, the rent here is paid according to the practical area, and it is unreasonable not to count the area.
