Do I need consent to remove a wall?
Opening up a room can change how your home feels. Whether you need consent depends on what the wall does. Some internal walls only divide space. Others carry the roof or floor above, or help the house resist wind and earthquakes.
Walls you can usually remove without consent
Work on an internal wall in an existing building can be exempt from building consent, as long as the wall is not:
- Load-bearing (supporting the roof, ceiling or floor above)
- A bracing element (helping the house resist wind and earthquakes)
- A fire separation wall
- Part of a fire safety system, such as alarms or sprinklers
- A masonry wall, such as brick or concrete block
How to tell what a wall does
You often can’t tell by looking. Original plans in your property file may show load-bearing and bracing walls. A builder, designer or engineer can confirm on site. If there is any doubt, treat the wall as structural until someone qualified says otherwise.
Before you start
- Check for wiring, plumbing and ducts inside the wall
- In homes built before 2000, test for asbestos before cutting or sanding
- Plan how the floor, ceiling and finishes will be repaired
Common questions
What happens if I remove a load-bearing wall without consent?
The house can sag or crack, and the work may count as unconsented. That can affect insurance and a future sale.
Where can I find my house plans?
Auckland Council holds property files for most homes. They often include plans from earlier consents.
