This may be the single most misunderstood phrase in Australian vacant-land marketing. "DA approved" can mean almost anything — from "the council is willing in principle" through to "we have a registered plan, services at the boundary, and you can lodge construction drawings tomorrow." The wording is rarely a lie, but it's almost always shorter than the truth.

Planning law in Australia separates two distinct approvals. The subdivision approval answers a question about the land: can this parcel exist as separate lots, and is residential use permissible? The construction approval answers a question about a specific building: does this proposed house meet the National Construction Code and the conditions attached to the subdivision? A subdivision approval — by itself — gives you a lot. It does not give you the right to build any particular house on it.

The full chain typically runs like this. First, a subdivision DA (or planning permit in Victoria, or development approval in Queensland, depending on the state). Then engineering and operational works approvals — sign-off on the civil engineering for roads, drainage, sewer and water. Then construction of those subdivision works by the developer. Then a Subdivision Certificate (NSW), Statement of Compliance (VIC), Plan Sealing (QLD) or equivalent — the council's confirmation that the developer has met all conditions. Then the plan is registered at the state land titles office, and only then do the new lots legally exist with their own titles. Once you have a registered title, you can start a separate process for a Construction DA (or Building Permit, or Complying Development Certificate), followed by a Construction Certificate, then critical-stage inspections during the build, then an Occupation Certificate (or Occupancy Permit) when the house is complete.

A "build-ready" lot is one where the plan is registered and the title issued, services are connected to the boundary, any developer-imposed design covenants are known and reviewable, and no outstanding subdivision conditions remain to be discharged. Anything short of that is a lot still in progress, and a buyer should know which step it's at.

State terminology adds confusion. NSW uses "DA" (Development Application). Victoria calls the planning approval a "Planning Permit" and the construction approval a "Building Permit." Queensland's Planning Act 2016 has its own taxonomy — MCU (Material Change of Use), ROL (Reconfiguring a Lot), Operational Works, and Building Work. WA, SA, Tasmania, the ACT and NT each have their own variants. The substance is similar everywhere, but the labels and timelines vary.

Questions worth asking the seller:

  • Is the plan of subdivision registered, and can you show me the new title and deposited plan number?
  • Are all subdivision conditions fully discharged, or are some ongoing (landscape maintenance, infrastructure works)?
  • What approvals are still required between today and slab-down on a typical home?
  • Are there deferred infrastructure contributions I'll inherit (Section 7.11 in NSW, GAIC in Victorian growth corridors, infrastructure charges in Queensland)?
  • Are mandatory design and siting covenants in place, and what is the developer-approval process?
  • Has the council flagged any conditions that survive settlement?
  • What is the currency period of any approval — when does it lapse?

Who can help. A town planner (Planning Institute of Australia-registered, often with the post-nominals RPIA or CPP) interprets the planning scheme and identifies what's permissible — typically $1,500–$5,000 for a property-specific feasibility. A private accredited certifier (NSW), building surveyor (VIC/SA/WA/TAS) or building certifier (QLD/ACT/NT) issues construction and occupation certificates. An architect or building designer prepares the construction approval documents.

A useful sanity check. For a registered, build-ready lot, a typical project home takes 10–18 months from purchase to Occupation Certificate. A custom architect-designed home in a complex council area is more often 18–30 months. If marketing implies you could be in the house in six months, ask exactly which steps in the chain have been completed — and how the timeline accommodates those that haven't.

The point of asking these questions is not to catch the seller out. It's to ensure everyone is using the same words to mean the same things, and that the asking price reflects what you're actually getting.

Approval terminology, timeframes and fees vary by state, territory and council and are subject to change. Always engage qualified professionals — a town planner, conveyancer or solicitor, and accredited certifier — and request from the seller copies of every approval document, condition of consent and certificate referenced above. Independent advice should be obtained before making any property decision.
