Find the constraint before you pay for the site
Most Victorian feasibility errors are not close calls. They are mandatory controls treated as negotiable, and schedule figures assumed from another job.
Where Victoria catches people out
You budget on a yield and expect to argue the garden area down
Minimum garden area is a mandatory zone control — Clause 32.08-4 in the GRZ, 32.09 in the NRZ, 32.07 in the RGZ. A permit cannot be granted below it and there is no discretion to reduce it: 25% on lots of 400–500 m², 30% on 501–650 m², 35% above 650 m². It applies to a single dwelling as much as to multi-dwelling development.
The block is well over the minimum lot size, so it must yield an extra lot
Every resulting lot counts, including the balance lot you keep. One additional lot means two lots and needs at least twice the minimum. At a 4,000 m² minimum a 6,081 m² site cannot be subdivided at all. The minimum also comes from the schedule to the zone, which overrides the standard default and is lot-specific.
You price the deal off the zone
The zone is the headline; the schedule is the substance, and overlays sit on top of both. A heritage, bushfire, flood or significant landscape overlay can require a permit for work the zone would exempt, and a covenant or Section 173 agreement on title prohibits outright what the scheme allows.
What to use, and when
Planning Insight

Detailed Planning Assessment

Certificate of Title & Plan
from $30The covenant or Section 173 agreement that stops a project is on title, not in the planning scheme, and is not visible from the address.
Getting started
Run the free snapshot across the shortlist, escalate the ones worth pursuing, and order the title before you exchange. The constraint that kills a Victorian deal is usually mandatory or registered — neither is negotiable, and both are knowable in advance.
