Some external door, window, wall or wall opening alterations don’t need development or building approval if they comply with rules set out in regulations.
Exemption from development approval
You don’t need development approval if an alteration complies with relevant provisions (Schedule 1, Part 1.3, Division 1.3.1, Section 1.21 and 1.21A of the Planning and Development Regulation 2008).
Alterations could include bricking up an external window, enlarging a window, converting a window to a sliding glass door, converting a window to double doors, and cutting a doorway or window into an external wall.
An alteration does not need development approval if you are:
- replacing a door or window without changing the width of the opening in the wall
- increasing the width of the door or window by no more than 340mm
- increasing the height of the door or window by no more than 340mm
- reducing the height or width, or both, of the window or door
- installing a wall instead of the door or window or a part of the door or window
- no part of it is within 1.5m of a side boundary or 3m from a rear boundary
- installing a door or window less than 2m wide in an exterior wall that is less than 1m above natural ground level (Low impact)
Note: an alteration does need development approval if you are installing a door or window on a floor more than 1m above ground level (High impact).
You should also consider other general exemption criteria that may apply.
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 the site is on national land you should contact the National Capital Authority for development approval.
