Some antennas, aerials and support structures don’t need development or building approval if they comply with rules set out in regulations.

Exemptions from development approval

You don’t need development approval if a mast antenna complies with relevant provisions (Schedule 1, Part 1.3, Division 1.3.2, Section 1.60) of the Planning and Development Regulation 2008, Schedule 1.


A mast antenna and support structure doesn’t need development approval if:

  • it isn’t a transmitting-only antenna
  • its diameter isn’t wider than 0.75 metres
  • it is no higher than 6m from its highest to lowest part, excluding any part that is in ground or part of another building or used for a purpose other than supporting the aerial
  • if the antenna is mounted on a building, the antenna isn’t more than 1.5 metres above the highest point of the building and the antenna’s colour matches the colour of the building
  • Mast antennas are classified as class 10 buildings. Additional criteria apply if two exempt class 10 structures are built within 1.5m of a side or rear block boundary. More.

If you are seeking to build on a rural block different exemption rules apply. (See Schedule 1, Part 1.3, Division 1.3.5, Section 1.85 of the regulation).

If you are still unsure whether your development is exempt you should check the regulation or call EPD Customer Service Centre on 6207 1923.

A building certifier can ensure plans and work are completed in accordance with the law.
