Kitchen exhaust and your Form 3: what SA building owners lodge, and when.
One dated obligation touches kitchen exhaust in South Australia, and it lands on the owner’s desk every January. Here it is in plain English.
Every year, in writing, within 60 business days.
A South Australian building with Essential Safety Provisions carries a schedule of them — the fire and life-safety features it must keep working for as long as it stands: sprinklers, alarms, exit systems, and the fire and smoke control features of its mechanical services. Kitchen exhaust systems sit in that last group where they appear on the building's ESP schedule.
Each year the owner must confirm to council, in writing, that those provisions have actually been maintained. In South Australia that confirmation is Form 3, the ESP maintenance verification, lodged within 60 business days of the end of the calendar year. In practice: last year's paperwork is due by roughly the end of March, and the maintenance evidence behind it has to already exist by 31 December.
The authorities: PlanSA publishes Form 3 and administers the planning-and-building framework it sits under; the SA Metropolitan Fire Service is the fire-safety authority for maintenance of installed fire safety systems.
The instrument: Regulation 94(11) of the Planning, Development and Infrastructure (General) Regulations 2017 (SA), under which Form 3 is the approved form for annual verification to council, read with Ministerial Building Standard MBS 002 — Maintaining the performance of essential safety provisions — which sets the maintenance requirements listed on the building’s ESP forms.
A fire load inside
the building fabric.
The maintenance standard behind most ESP line items is AS 1851-2012 — routine service of fire protection systems and equipment. Its Section 13 covers the fire and smoke control features of mechanical services, which is where a commercial kitchen's exhaust system lives: the canopy, filters, ductwork and fan that carry grease-laden air out of the building. Grease accumulating in that ductwork is a fire load sitting inside the building fabric — a fire-safety maintenance item, not a housekeeping one.
A Form 3 signed on the strength of an unserviced or unevidenced exhaust system is a verification the owner cannot stand behind. What stands behind it properly is measured evidence: grease-depth readings against the AIRAH Best Practice Guideline benchmark, identical-position photographs, full-vs-partial disclosure and a numbered deficiency register — the record an auditor, insurer or fire authority can verify after the fact.
Six questions, one document
| Question | Answered by |
|---|---|
| Was it serviced? | Dated works report |
| To what standard? | AS 1851-2012, named |
| Measured how? | Readings in microns vs the AIRAH benchmark |
| Whole system? | Full-vs-partial disclosure |
| By whom? | Named technician, numbered certificate |
| What is outstanding? | Numbered deficiency register |
What managing agents
most often get wrong.
- Treating the invoice as the evidence. A paid invoice proves a visit happened, not that the system meets criteria. Verification needs measurements and photographs, not a line item.
- Accepting a sticker as a certificate. A dated sticker on the canopy says nothing about the duct runs the sticker never saw.
- Partial service recorded as full service. Sections with no access panels silently skipped, with nothing on paper disclosing it — the gap an assessor finds first.
- Assuming the tenant's arrangement discharges the owner's duty. The lodgement duty sits with the owner. A tenant's ad-hoc contract on the tenant's schedule does not automatically produce the evidence the owner's Form 3 relies on — and the owner usually never sees what it produced.
- Discovering the gap in February. The verification covers the calendar year just ended. If the maintenance did not happen by 31 December, there is nothing compliant to verify — the deadline can be met on paper and still be hollow.
What stands behind
the kitchen exhaust line.
Readings in microns
At every access point opened, before and after works, against the AIRAH Best Practice Guideline benchmark — mean grease depth below 0.2 mm (200 μm), no single reading above 2 mm (2,000 μm).
Identical-position photographs
Before and after, from the same position and framing, one label per pair.
Full-vs-partial disclosure
Whether the whole system was serviced or only part of it, and every unreached section with the reason.
A numbered deficiency register
Location, severity, photo reference, recommended action — what was known and what was recommended, on the record before the signature.
Before the Form 3 is signed, measure the asset.
A site survey tells the owner or agent, in writing, exactly where each kitchen exhaust asset stands against its servicing standard — measured, photographed, and specific enough to hand to whoever signs.
