SLF, also known as Sertifikat Laik Fungsi, is a certification that attests to the functional suitability of a completed building. This certification indicates that the building meets all necessary administrative and technical requirements corresponding to its intended function. Achieving functional appropriateness means the building complies with regulations and standards set forth for its specific use, ensuring it is safe, operational, and legally recognized for its designated purpose.
Without an SLF, a building may be considered legally constructed and existing; however, it cannot be legally utilized for its intended function. This means that, despite its physical presence and adherence to construction standards, the building lacks the official approval for occupancy and operation. Therefore, obtaining an SLF is essential for validating both the construction process and the building’s functional use, thereby legitimizing its occupancy and ensuring compliance with all relevant laws and regulations.
