A Certificate of Building Fitness for Use (SLF, Sertifikat Laik Fungsi) is not a one-time document. For most buildings in Indonesia it must be renewed periodically, and every SLF renewal starts with a fitness-for-use inspection by a technical assessor. This article sums up the legal basis, the steps and the documents you should prepare well before your SLF expires.

The main rules are in Government Regulation (PP) No. 16 of 2021, which implements Indonesia's Building Law. The most relevant articles are:

  • Article 297(1) and (2): an SLF must be renewed after a set period: 20 years for detached and terraced houses, and 5 years for all other buildings.
  • Article 297(3): renewal is preceded by a fitness-for-use inspection.
  • Article 298(1): the inspection is carried out by a technical assessment provider.
  • Article 302(2): the owner or user applies for renewal through SIMBG, the government's building management information system.

So for offices, hotels, hospitals, malls, apartments and factories, SLF renewal runs on a five-year cycle. Local governments may add their own technical rules, so check the requirements of the city or regency where your building stands.

Steps in an SLF renewal

In outline, the process looks like this:

  1. Gather building data. Collect the previous SLF, the building approval (PBG, or the older IMB), as-built drawings and the periodic inspection reports from the period of use.
  2. Appoint a technical assessor. The owner appoints a technical assessment provider with the required competence and certification.
  3. Fitness-for-use inspection. The assessor inspects the building using a checklist, compares site conditions with the as-built drawings from the last SLF, and prepares a report and a statement of fitness for use.
  4. Apply through SIMBG. Once the statement is issued, the owner or user applies to the city or regency government through SIMBG.
  5. Verification and issue. The local government checks the documents and issues the SLF. Under Article 302(3), no fee is charged for the SLF issued from this application. The technical assessor's fee is a separate matter.

Tip: Start preparing several months before your SLF expires. If the inspection finds damage or unrecorded changes, you will need time for repairs or updated drawings before you apply.

Documents to prepare

Requirements vary slightly between local governments, but usually include:

GroupTypical documents
AdministrativePrevious SLF, PBG or IMB, proof of land rights, owner identity
DrawingsAs-built architectural, structural and MEP drawings matching the site
MaintenancePeriodic inspection reports and maintenance records for the SLF period
TechnicalFitness-for-use inspection report and statement from the technical assessor

The item most often missed is the as-built drawings. Article 297(4) and (5) of PP 16/2021 state that the inspection considers whether site conditions match the as-built drawings from the last SLF, and that the owner must update the drawings if they do not. Renovations, new mezzanines or layout changes from the past five years need to appear on the drawings.

Periodic inspections during the SLF period

Renewal goes much more smoothly when the building is maintained and inspected regularly. Article 295(5) of PP 16/2021 requires periodic inspections at least once every six months, unless technical standards set another interval, with results recorded in a report. Article 298(4) says the assessor's checklist takes these periodic inspection reports into account.

In other words, periodic inspection reports are not just paperwork for the archive. They show the building has been looked after, and they feed directly into the renewal.

The role of the structural assessment

The fitness-for-use inspection covers safety, health, comfort and accessibility. For the structure, the technical assessor typically carries out:

  • A visual inspection of columns, beams, slabs, shear walls and connections, looking for cracks, corroded reinforcement, leaks and deflection.
  • A review of changes in load and use, such as offices turned into heavy archive storage, or new equipment placed on the roof.
  • Field testing where needed, for example non-destructive tests such as the rebound hammer to estimate concrete strength.
  • Recommendations for repair or strengthening if problems are found, before the statement of fitness is issued.

If there are findings such as cracks that keep widening, or a change of use that adds load, a more detailed evaluation or structural audit may be needed. For buildings on soft ground, foundation data from the original project also helps, as discussed in Bored Piles vs Driven Piles.

Common mistakes

  • Looking for a technical assessor only when the SLF is about to expire.
  • Not updating as-built drawings after renovations.
  • No periodic inspection reports for five years.
  • Changing how rooms are used without checking the effect on the structure.

Conclusion

For buildings other than houses, SLF renewal is a five-yearly event you can plan for. What makes it go smoothly is up-to-date as-built drawings, well-kept periodic inspection reports and a fitness-for-use inspection by a competent technical assessor. The outcome still depends on the building's condition and the local government's verification.
