Nowadays, the Certificate of Functional Worthiness (SLF) is a document that shows that a building has met the standards of safety, health, comfort, and environmental worthiness in accordance with applicable regulations. The development of the industry requires the government to issue SLF as a legalization of buildings and hotels in Bali. In the context of tourism, especially for lodging buildings such as hotels, resorts, and villas, the publication of SLF is very important to ensure that the building is not only safe for visitors, but also supports the desires of the tourism sector. The purpose of this study is to analyse the SLF regulations for building tourism in Bali Province, as well as the challenges in its implementation; and to see the extent to which tourism actors have mentioned the rules on tourism accommodation that apply in Bali Province, especially related to the implementation of the Certificate of Functional Worthiness (SLF). The formulation of the problem in this study: (i) Regulation of the Certificate of Functional Worthiness (SLF) for tourism hotel buildings in Bali Province, (ii) How is the government's commitment to implementing the Certificate of Functional Worthiness (SLF) for tourism hotel buildings in Bali Province. This study uses a qualitative descriptive approach research method with case studies on several tourism buildings in Bali. The results of this study relate to the regulation of the certificate of functional feasibility (SLF) for tourism accommodation buildings in Bali Province so that its implementation can guarantee the safety and comfort of tourists. The Bali Provincial Government has shown a high commitment in implementing the certificate of functional feasibility (SLF) to build tourism accommodation by issuing clear regulations. The implication for the implementation of the certificate of functional feasibility (SLF) is that every tourism industry player who has so far paid less attention to the SLF must be required to implement the SLF in the tourism hotel buildings they own.
