Permit Guide: Getting MBJB/MBIP Approval for Home Extensions
House extensions — additional rooms, extended kitchens, or a second floor — usually require approval from your local town council, whether that's Majlis Bandaraya Johor Bahru (MBJB) or Majlis Bandaraya Iskandar Puteri (MBIP). Skipping this step can lead to fines or a forced demolition order.
When Do You Need Council Approval?
- Any addition to the building footprint (room, porch enclosure, extension)
- Adding a second storey or raising roof height
- Structural changes affecting shared walls (for terrace/semi-D units)
- Changing the use of a space (e.g. converting a car porch into a room)
Documents You'll Typically Need
- Copy of land title / strata title
- Building plans prepared and endorsed by a registered architect or engineer
- Original house building plan (if available)
- Letter of consent from neighbours for shared-wall extensions
- Structural calculation report for major additions
The General Approval Process
While requirements can change, the general flow for MBJB and MBIP building plan submission follows a similar structure.
- Engage a registered architect/engineer to prepare submission drawings
- Submit building plan application through the council's One-Stop Centre (OSC)
- Council technical departments review structural, fire safety and drainage compliance
- Approval issued, followed by Certificate of Completion and Compliance (CCC) after construction
Common Reasons for Rejection or Delay
- Extension exceeds plot ratio or setback requirements
- Missing structural endorsement from a qualified engineer
- Drainage plan not accounted for (a common issue in flood-prone Johor areas)
- Incomplete neighbour consent documentation

Frequently Asked Questions
Do I need MBJB approval to renovate the inside of my house?
Purely cosmetic interior work (painting, cabinets, flooring) generally does not need council approval. Approval is required once you change the building footprint, structure, or use of a space — such as extending the kitchen or enclosing the car porch.
How long does MBJB or MBIP building plan approval take?
Straightforward residential extension plans submitted through the One-Stop Centre (OSC) commonly take several weeks to a few months, depending on completeness of documents and whether technical departments request amendments.
What happens if I extend my house without approval in Johor?
The council can issue fines, stop-work orders, or require demolition of the unapproved structure, and unapproved extensions complicate future property sales. Getting approval first is always cheaper than fixing it later.
