IMB (the pre-2021 building permit) , Bali villa glossary

In one sentence. The building permit in force until 2021. It was replaced by the PBG, but buildings older than five years still carry an IMB in their files.

IMB (Izin Mendirikan Bangunan) was the building permit issued before the Cipta Kerja law and PP 16/2021 took effect. Since 2021 new buildings receive a PBG, while previously issued IMBs remain valid for the buildings they covered.

On the resale market this means a 2015 villa will have an IMB, not a PBG, and that is normal. There are three checks. The IMB covers this building (area and storeys), the building has not been extended beyond the permit, and an SLF exists. Older buildings often lack one and must obtain it before commercial rental.

If the seller of a new build shows an "IMB", that is a red flag, since no such document has been issued since 2021.

Updated 2026-09-20. Not a public offer. Regulations change, so we cite enacted acts only and update the entry when they do.
