SLF
Also called Sertifikat Laik Fungsi, certificate of worthiness
SLF, or Sertifikat Laik Fungsi, is the certificate confirming a completed building is fit for use, issued after construction and inspection, and it is separate from the PBG that authorised the build.
PBG is permission to build. SLF is confirmation that what you built is actually fit to occupy, granted after the work is done and inspected against the approved design. A building can hold a valid PBG and still not have an SLF, which means the paperwork chain is incomplete.
The formal SLF application is usually lodged once the building is around 90% complete, not at handover. But the process starts well before that in practice: the inspections, as-built records and documentation the certificate depends on need to be kept from the start of construction, not assembled retroactively once the building is finished.
This has become sharper for villa owners letting to guests. Indonesian compliance requirements for tourist accommodation now expect the full set: a business identification number, a valid PBG, and an SLF. Villas listed on booking platforms fall inside that scope, and a compliance deadline for this passed in March 2026.
If you own a villa in Bali that takes paying guests and you are not certain whether it holds an SLF, that is worth establishing now rather than at the point someone asks.
Where people get caught
Assuming the certificate exists because the villa was built by a reputable contractor and has been operating for years. Operating history is not evidence of compliance. Check the actual document.
Where this comes up
This is general information, not legal advice. Indonesian property law changes, and how it applies depends on your situation, your visa status and the specific plot. Always take advice from a qualified notaris before you commit money. Last checked 2026-08-25.
