Relevant rules in the Regulation:

  • Schedule 1, Part 1.4, Division 1.4.1, Section 1.28.

Examples of skylights include:

  • windows in a roof
  • light shafts and ceiling openings with light diffusers, and
  • cutting a tube-type skylight into a roof and ceiling.

A skylight doesn't need DA approval if:

  • the external area isn't more than 2m2
  • it doesn't project more than 150mm above the surface of the roof next to the skylight, and
  • the skylight doesn't project beyond any relevant solar building envelope it complies with relevant general exemption criteria.

Note: If you're changing the external appearance, material or finish of a building or structure, other requirements apply. For example, heritage requirements and energy efficiency provisions of building laws.
