IMB No Longer Exists — But Buildings Still Need Permits

In 2021, the Job Creation Law (UU Cipta Kerja) fundamentally restructured the building permit system. IMB (Izin Mendirikan Bangunan — Building Construction Permit) that had been familiar for decades was replaced by PBG (Persetujuan Bangunan Gedung — Building Approval). This isn't just a name change — the concept and process changed too.

Important to know immediately: IMBs issued before PP No. 16/2021 came into effect remain fully valid and do not need to be replaced. But for new construction or renovations that alter the structure, you need PBG.

What's the Difference Between IMB and PBG?

IMB was a permit granted before construction began — it was a front-end verification mechanism. PBG focuses more on compliance with technical standards throughout the construction process and upon completion.

Other significant changes:

  • IMB was issued by local government; PBG is also local government but more integrated with the OSS (Online Single Submission) national system
  • PBG is accompanied by an SLF (Sertifikat Laik Fungsi — Certificate of Functional Worthiness), which certifies the building meets technical standards and is fit for occupancy
  • Building supervisors are more formally involved in the PBG process

When Is PBG Required?

  • Building a new house on vacant land
  • Adding a floor (building upward)
  • Extending floor area (expanding sideways or to the rear)
  • Changing the building's function (e.g., residential to commercial)
  • Renovations that alter the main structure (columns, beams, foundation)

For non-structural renovations — repainting, retiling, or interior renovations without structural changes — PBG is not required.

Documents Required for a Residential PBG

  • PBG application form (available at local DPMPTSP or online via OSS)
  • KTP of the owner/applicant
  • Proof of land ownership (SHM, HGB, or land ownership certificate)
  • Architectural and structural drawings (prepared by a registered architect/designer)
  • Building technical specifications
  • Environmental documentation (for buildings with total floor area over 200 m²)

Application Process

Online Route (Recommended)

  1. Register or log in to the SIMBG system (Sistem Informasi Manajemen Bangunan Gedung) at simbg.pu.go.id
  2. Fill in the application form and upload all documents
  3. The system automatically verifies document completeness
  4. If complete, the application is forwarded to the relevant technical department for review
  5. Technical staff may conduct a site visit
  6. PBG is issued once all requirements are met

Offline Route

Visit the local DPMPTSP (One-Stop Licensing Service Office) in your city or district. Bring all documents in physical form. This route is slower but appropriate if you're less comfortable with the digital system.

How Long Does It Take?

Under regulations, PBG processing should be completed within 28 working days for simple buildings (1–2 story residential homes). In practice, timelines vary significantly by region — some areas process quickly with well-functioning systems, others are slower due to administrative backlogs.

What Does It Cost?

PBG fees are calculated using an Integrated Index that accounts for building area, function, and location. For a simple residential home, the fee typically ranges from a few hundred thousand to a few million rupiah. The official fee is set by each city's Local Regulation (Perda) — ask your local DPMPTSP for the specific figure in your area.

What's the Risk of Building Without PBG?

Buildings without PBG are legally subject to administrative sanctions up to and including a demolition order. More practically: a property without complete permit documentation creates serious obstacles for KPR applications (banks require IMB/PBG), property sales, and building insurance claims.
