What Is SLF in Indonesia?

Sertifikat Laik Fungsi (SLF) = Certificate of Building Worthiness

If you’re building or buying property in Bali, there’s one certificate you must obtain before using the building: the SLF.

What Is SLF?

SLF (Sertifikat Laik Fungsi) is an official certificate issued by the Indonesian government to confirm that a building is safe, legal, and ready for use. Without it, you cannot legally operate or live in the building.

Who Issues It?

The SLF is issued by the Ministry of Public Works and Spatial Planning (PUPR) via the SIMBG system — Indonesia’s national online permit portal.

Validity Period:

What Do Authorities Check Before Issuing SLF?

1. Compliance with original building permit (PBG)

2. Structural safety (beams, foundations, evacuation routes)

3. Electrical and fire safety systems

4. Environmental documents (SPPL, UKL-UPL, or AMDAL)

5. Urban planning compliance

6. Accuracy of submitted documents

Documents Required to Apply for SLF:

• Architectural and structural drawings

• Construction reports and safety test results

• Photos of the completed building

• Land ownership documents or lease agreement

• Tax proof (PBB)

• SKRK (zoning certificate)

• IPPT (land use permit)

• Environmental compliance documents (SPPL / UKL-UPL / AMDAL)

• ID of the owner or company legal documents

Why Is SLF So Important?

• Without SLF, you legally cannot use or rent the building

• Operating without SLF can result in:

  • Fines

  • Forced closure

  • Demolition

  • In severe cases: up to 5 years in prison

   

• If SLF was obtained improperly (using false data), it can be revoked at any time, even after the building is in use

Summary:

Getting SLF is not optional — it’s the final step to make your building legal and usable.

If you’re unsure how to apply or want help with documentation, it’s highly recommended to work with a local architect or legal consultant who understands the process.
