Clause 55 for a second dwelling
Adding a second dwelling to a residential site brings the proposal into Clause 55. The standards are the same everywhere — but the answer is set by the site in front of you, long before any decision guideline is reached.
Two dwellings brings in Clause 55
A single dwelling on a site in these zones generally isn't assessed under Clause 55 at all. The moment a second dwelling is proposed on the same site, the application must be assessed against Clause 55 — part of the ResCode provisions — in the relevant residential zones. That's a step up in rigour: Clause 55 works through a set of objectives, each paired with a standard, and backed by decision guidelines. The proposal is tested against each one.
Standard, objective, decision guideline
The structure matters because it sets how a finding should be expressed. Each standard is a measurable test — a setback, an amount of private open space, a site coverage figure. Where a proposal meets the standard, it complies. Where it doesn't, that's not automatically a refusal: the responsible authority may still be satisfied the objective is met, having regard to the decision guidelines. That's a variation — a considered judgement that the objective is achieved even though the standard is not.
"Complies subject to information or a condition" is not a variation
This is the distinction most worth getting right, and the one most often blurred. When a standard broadly complies but a single detail needs to be confirmed off the plans — a setback that reads as compliant but isn't dimensioned, an open-space area that looks adequate but isn't labelled — the correct finding is complies, subject to additional information or a condition on any permit issued, identifying what to confirm or condition. It is still a compliance finding; it just flags the detail.
Escalating that to a variation overstates the planning issue. A variation signals genuine non-compliance that needs the decision guidelines to resolve. Reserve it for that. Reaching for it whenever a plan is under-dimensioned turns a documentation gap into an apparent merits problem — and makes the assessment read as more contentious than the proposal actually is.
The site decides before the guideline does
Almost every Clause 55 standard is a function of the site itself. Site coverage and permeability are proportions of the site area. Private open space, setbacks and overlooking turn on the site's dimensions and orientation. And, separately, whether a garden area requirement applies under the zone — and how much — depends on the site size. So you cannot assess Clause 55 in the abstract: the answer is largely fixed by the site's real area, shape and frontage before you reach any qualitative guideline.
This is why a generic "a second dwelling on a typical site usually complies" is the wrong instinct. The standards are statewide, but they resolve to numbers that come from this site. An assessment that doesn't start from the actual site dimensions is guessing.
How PlanSuite assesses it
PlanSuite anchors the Clause 55 assessment to the proposal's real identity — what's retained, what's proposed, and the site's actual dimensions — and reads the standards against that, rather than re-deriving the proposal differently for each standard. Where a standard broadly complies but a detail needs confirming, it records that as complying subject to additional information or a condition on any permit issued; it reserves "variation" for genuine non-compliance where the decision guidelines are in play. Every finding is tied back to the standard it's assessed against, so the reasoning is checkable against Clause 55 itself.
