(1) A class B unit is a unit that is identified as a class B unit—
(a) before a units plan is registered—in the relevant unit title application; or
(b) after the relevant units plan is registered—in the units plan.
(2) After a units plan is registered, a "class B unit" of the units plan includes any unit subsidiary shown on the units plan as annexed to the unit.
Note A unit title application must show a class B unit as land unlimited in height, except to the extent of any encroachment, whether at, above or below ground level, by another part of the parcel (see s 18).
