Reference
Most references tell you a control exists and where to find it on a map. These pages start one step later: what the control actually sets, whether that number can be argued with, what a schedule or a second map can do to it, and which question you have to take to the council rather than to a reference page.
Victoria
A Victorian zone states its height and storey limits in the ordinance itself, and a schedule to the zone varies them. Overlays sit on top and add their own.
New South Wales
A NSW zone settles what you may build through the Land Use Table; how big it may be comes from separate maps — height of buildings, floor space ratio, minimum lot size — each with its own clause in the LEP.
The most expensive mistake in moving between these states is assuming the zone means the same thing. In Victoria the zone is the control: the General Residential Zone sets eleven metres, and a schedule adjusts it. In New South Wales the zone is a permissibility test and nothing else — R3 does not set a height, a floor space ratio or a lot size, and a site’s yield comes from three separate mapped standards that can be, and often are, varied independently of one another.
The second difference is what happens when you want more than the standard allows. Victorian residential siting standards are mostly discretionary, so exceeding one is a merits argument against the standard’s objective; the zones’ maximum heights are mostly requirements no permit varies. NSW development standards are contravened through a specific clause — clause 4.6 — with its own written test, and a few standards are put beyond its reach altogether.
