Victorian planning controls
Zones and overlays as they affect what you can build. Each page states what the control sets, whether that figure is a requirement or a standard, and where the number that actually binds a site is likely to be instead. Written against the ordinance rather than around it.
Zones
A zone is on every parcel of land in the state, and it is the first thing that decides what the land can become.
| Control | What it is | Reference |
|---|---|---|
| HCTZ | Housing Choice and Transport ZoneMandatory heights that change with the schedule number and again with site size — the large-site uplift and why consolidation matters. | Clause 32.10 |
| NRZ | Neighbourhood Residential ZoneThe most restrictive of the residential zones — nine metres, two storeys, and a garden area that decides more projects than the height does. | Clause 32.09 |
| GRZ | General Residential ZoneVictoria’s default residential zone, and the one whose street setback most published guidance still gets wrong. | Clause 32.08 |
| RGZ | Residential Growth ZoneThirteen and a half metres, and no storey maximum at all — the second half of that sentence is the one people miss. | Clause 32.07 |
| MUZ | Mixed Use ZoneThe zone that sets no height. Every number that binds a Mixed Use lot lives somewhere the zone cannot see. | Clause 32.04 |
Overlays
An overlay sits on top of the zone and adds a permit trigger, a referral, or a set of built-form controls that the zone knows nothing about.
| Control | What it is | Reference |
|---|---|---|
| DDO | Design and Development OverlayThe parent clause sets no built-form numbers. Every height, street wall and setback that binds is in the schedule the overlay number points at. | Clause 43.02 |
| HO | Heritage OverlayIn preparationMaps a curtilage, not a rule — and sets no height limit of its own. | Clause 43.01 |
| ESO | Environmental Significance OverlayIn preparationThe overlay records where; the schedule records why, and cites the study it came from. | Clause 42.01 |
| VPO | Vegetation Protection OverlayIn preparationMaps a control area, not trees. A cleared lot inside one is still inside one. | Clause 42.02 |
| LSIO | Land Subject to Inundation OverlayIn preparationModelled flood extent, adopted into the scheme on amendment cycles. The zone height is measured from the minimum floor level, not natural ground. | Clause 44.04 |
| SBO | Special Building OverlayIn preparationOverland stormwater flow rather than riverine flood — same floor-level mechanism, different authority. | Clause 44.05 |
| BMO | Bushfire Management OverlayIn preparationDefendable space is a footprint cost, and the extent tracks state remapping rounds. | Clause 44.06 |
