No plan is required for minor construction job.

Generally you don’t require plans for internal renovation provided you are not knocking out load-bearing walls – walls that are integral to the support of the building.  If they are support walls, you will require planning approval.  Internal remodelling like putting in a new bath or revamping the entire kitchen do not require plans, but if you are putting in a fireplace you DO require approval as there are fire regulations involved.  Even if you are intending to erect a boundary wall, Council approval is required.  As well if you are putting in a swimming pool, there are rules and regulations that have to be complied with and a plan is required.  Should you have wish to add another storey to your existing dwelling you will require an engineer’s report and plans must be submitted.  Another important aspect is if your building is going to be used by the public you will require a fire protection plan.
