A unit owner must not perform an act that is harmful to the preservation of the building or any other act that goes against the common interest of the unit owners in connection with the management or use of the building.
区分所有者は、建物の保存に有害な行為その他建物の管理又は使用に関し区分所有者の共同の利益に反する行為をしてはならない。
Within the scope necessary to preserve or improve an exclusively-owned area or a common area, a unit owner may request to use the exclusively-owned area of another unit owner or to use a common area not under their ownership, or to preserve these areas themselves. In such a case, if another unit owner incurs damage, the requesting unit owner must pay them compensation.
The provisions of paragraph (1) apply mutatis mutandis to a possessor of an exclusively-owned area who is not a unit owner (hereinafter referred to as the "possessor").
The provisions of Article 264-8 and Article 264-14 of the Civil Code (Act No. 89 of 1896) do not apply to exclusively-owned areas and common areas.
