The permit system changed in 2021 and a great deal of the advice circulating online still describes the old one. If someone tells you that you need an IMB, they are working from a framework that no longer exists.
Here is the current sequence, in the order it actually happens.
Step one: spatial conformity (KKPR)
Before any building approval, the intended use has to be consistent with the spatial plan for that parcel. This is the KKPR stage, confirmation that what you propose to do matches what the land is designated for.
This is where most projects fail, and they fail early and cheaply if you do it in the right order, or late and expensively if you do not. The RTRW is the provincial spatial plan; the RDTR is the detailed regency plan and, where it exists, it governs at plot level: coverage ratio, floor area ratio, height, setbacks, permitted use.
Practical consequence: establish classification before you buy land, not after. A parcel that cannot pass KKPR for your intended use is a different project, not a permitting problem.
Step two: PBG, approval to build
PBG, Persetujuan Bangunan Gedung, replaced the IMB under Government Regulation 16/2021. It approves your design before construction starts, confirming it meets technical, safety and zoning standards. It is required for a new build, an extension, or a major change to an existing building.
Applications go through SIMBG, the building management information system, which works alongside the OSS business licensing system.
Requirements worth knowing before you budget:
- Technical drawings must be signed off by a certified Indonesian architect (IAI) and a
certified engineer (SKA). This is not a formality you can satisfy with drawings from home.
- A complete submission typically clears in 14 to 30 working days.
- Realistically, allow three to four months end to end. The portal is fast; document
preparation and KKPR are not.
Step three: build
Nothing surprising here, except the timeline: 8 to 10 months for a simple two-bedroom villa, 12 to 14 months once a pool and landscaping are involved.
What matters legally is that what gets built matches what was approved. Deviating during construction because something looked better on site is one of the more common reasons the final step goes wrong.
Step four: SLF, clearance to use
SLF, Sertifikat Laik Fungsi, is issued after a site inspection confirms the completed building matches the approved plans. It is your clearance to actually use the building.
Treating SLF as optional paperwork is a mistake with a delayed cost. It surfaces when you try to sell, when you try to insure, when you try to connect certain utilities, or when someone official has a reason to look. A building without SLF is a discount waiting to be applied by a future buyer's lawyer.
Why a foreigner cannot hold a PBG
This is the structural point that reorganises everything above.
A foreigner cannot apply for a PBG personally. The application is made by the entity holding the land right. In practice, for anyone intending commercial use, that means a PT PMA holding HGB (Hak Guna Bangunan, the right to build).
Which pulls the company question forward in the timeline, because setting up a PT PMA is not instant and carries its own thresholds:
- Minimum investment above IDR 10 billion per line of business per location, excluding
land and buildings.
- Of the IDR 10 billion issued capital, IDR 2.5 billion must be paid up at incorporation;
the remainder may be loan capital.
- The investment plan must be realised within five years.
A widely repeated claim online is that the minimum capital requirement is IDR 2.5 billion. That figure is the paid-up tranche, not the requirement. Budgeting against it is how people discover a gap of IDR 7.5 billion at the wrong moment.
The sequence that saves money
Most permit disasters come from doing these in the wrong order. The order that works:
1. Confirm parcel classification and whether your intended use passes KKPR. 2. Decide the holding structure (lease, Hak Pakai, or PT PMA on HGB), because it determines who applies for what. 3. Engage a certified Indonesian architect and engineer. 4. Submit PBG through SIMBG. 5. Build exactly what was approved. 6. Obtain SLF.
Only step five is visibly construction. The other five are where the project is actually won or lost.
What happens when this is skipped
Building first and regularising afterwards is common enough to feel normal, and it is a bad trade in a way that has become worse.
In October 2025 a villa project in Karangasem was sealed over permit problems. A sealed site does not pause costs: crew, site rental, financing and lawyers all continue while nothing is built and nothing can be sold at value.
Meanwhile the enforcement environment tightened. In September 2025, following flooding that killed 17 people, the province prohibited conversion of productive agricultural land for commercial use, with instructions issued to every regent and mayor. Housing genuinely for personal residential use on private land is assessed case by case; a set of keyed units with a booking calendar is not that, whatever the drawings say.
The permit path costs three to four months and a defined sum. The alternative costs an undefined sum, on someone else's timetable.
Before you engage anyone
Ask for the parcel classification in writing with its plan reference. Ask which structure will hold the land right and therefore make the application. Ask for the architect's IAI registration and the engineer's SKA certification.
Three questions, answered in one message by anyone competent. The pattern of the answers tells you more about who you are dealing with than any portfolio will.
