Unauthorised Building Works

Unauthorised building works are any building works that were undertaken without the correct planning, building and/or plumbing approvals and can include patios, sheds, brick fences, retaining walls as well as building alterations or additions.

If you carry out work without a permit, you may be required to re-do the work and obtain the required approvals or remove/demolish the illegal works. Rectifying illegal building works can be costly and there may also be increased fees if you are issued with an infringement notice.

Many building works require approval before they can begin. However, not all works require approval.

How to deal with unauthorised building works on your property

If you have undertaken building work without prior approval, or purchased a property with unauthorised structure/s, you will need to submit a Building Information Certificate (BIC) Application to obtain approval.

  • In certain circumstances the Council may give favourable consideration to a BIC application which may allow an unauthorised structure to remain.
  • You will need to be able to clearly demonstrate that the unauthorised development meets the relevant and applicable planning objectives and development controls.
  • Applying for a BIC for unauthorised work does not guarantee approval and Council may issue a Notice/Order for the demolition of the unauthorised building or portion.
