Legal protection for common land objects in the management and establishment of the Association of Owners and Residents of Apartment Units (Perhimpunan Pemilik dan Penghuni Satuan Rumah Susun or PPPSRS) is a crucial issue requiring special attention. Common land objects, as essential elements in apartment units, often face legal challenges related to ownership, usage, and management due to delays and inertia in the formation and regulation of PPPSRS. This study aims to analyze the available legal protection for owners and residents of apartment units regarding common land objects and to identify obstacles in the formation and management of PPPSRS. The research adopts a normative juridical method with a legislative approach, case studies, and relevant document analysis. The findings reveal that delays in establishing PPPSRS, caused by a lack of legal understanding or implementation delays, negatively impact the management of common land objects. Therefore, strengthening regulations, oversight, and legal awareness among owners and residents is essential to ensure effective management and optimal legal protection.
