Del. Code tit. 25, § 2232

Each unit and its proportionate undivided interest in the common elements, as determined by the declaration and any amendments thereof, shall be assessed and taxed for all purposes as a separate parcel of real estate entirely independent of the building or property of which the unit is a part. Neither the building, the property nor any of the common elements shall be assessed or taxed separately after the declaration and declaration plan are recorded nor shall the same be subject to assessment or taxation except as the units and their proportionate undivided interests in the common elements are assessed and taxed pursuant to the provisions of this section.
