IMB / building permit (Izin Mendirikan Bangunan)

IMB (Izin Mendirikan Bangunan) was the traditional building permit in Indonesia. For Bali villas, buyers and long-term renters sometimes still see IMB mentioned in due diligence, especially on older properties.

Regulations have evolved: new construction and significant changes may require permits under updated rules (including PB UMKU / “PBG” style licensing depending on period and local interpretation). What matters in practice is whether the structure on the land is documented in a way your notary and engineer accept for your use case—not only the old three letters “IMB.”

Always verify current paperwork with a qualified notary and, where needed, a structural survey—not only the marketing description.
