A Practical Guide to Building Permits in Indonesia
Since 2021, Indonesia's building permit system has run on PBG (Persetujuan Bangunan Gedung), which replaced the older IMB system. PBG is issued before construction starts, based on architectural, structural and utility drawings submitted to the local government, and it verifies that a design meets zoning, safety and technical standards for its category of building.
Once construction is complete, a separate document — SLF (Sertifikat Laik Fungsi) — certifies that the building was actually built the way it was approved, and that it's safe to occupy. Skipping this step is a common shortcut on smaller residential projects, but it becomes a real problem later, particularly when selling the property or applying for a mortgage against it.
The paperwork itself isn't the hard part; the timeline is. PBG approval can take anywhere from a few weeks to a few months depending on the region and building complexity, and that clock only starts once complete drawings are submitted — not when you first meet your architect.
The projects that avoid permit delays start this process in parallel with design development, not after it's finished. Building the permit timeline into the project schedule from day one, rather than treating it as a final step before groundbreaking, is the single biggest lever a client has over how long a project actually takes.
