Opening restrictors on first floor windows

A safety requirement treated as an accessory.

Owner Inspections · Leppington 2179 · 2026-03-13

In short: Three first floor windows without restrictors on one Leppington home.

What they do

They cap how wide a window above ground can swing, so a child cannot pass through.

What the Code asks

Restriction on windows meeting set height and sill criteria above ground, limiting the opening to a specified dimension.

What we recorded

Three first floor windows on a single Leppington home with the restriction required and not fitted.

Why it gets missed

It is a small hardware item on a window schedule, and it is invisible unless somebody opens the window and measures.

How it is reported

As a safety item, apart from the finish list, because the consequence is of a different order.

FAQ

Questions Leppington owners ask about this

Is it genuinely required?

Yes, wherever the criteria apply. We record which window, what was measured and what was required.

Can it be retrofitted?

Easily, which is why there is no good reason to leave it outstanding at handover.

Is every window upstairs caught by this?

No, only those meeting the criteria, which is why it is measured rather than assumed.

Who fits it?

Your builder, since it forms part of the window supply.
