Tradie Forms: complete QLD Form 16 on the official Queensland PDF layout while the stage inspection details are still fresh. Work through the stage, property, component, basis, reference, certifier, inspector, signature and date sections in one pass.
QLD Form 16 turns a site inspection into a formal stage record. It looks short until you are standing beside the slab edge, scrolling through drawings, checking lot and plan details and trying to describe exactly what the certificate covers.
Complete it while the inspection, photos, notes, plans and approval documents are still open and the record is usually sharp. Leave it until tonight and the stage description goes vague, reference documents shrink to "plans", and the office has to chase missing numbers before the next stage can move. This guide covers filling the certificate. For what happens to it afterwards, read keeping the Form 16 stage inspection record clean.

What is QLD Form 16 for?
Recording a stage inspection result. The official Queensland Form 16 PDF says it is the approved form used under section 10 of the Building Act 1975 and section 53 of the Building Regulation 2021, used by the relevant building certifier, another building certifier, or an appointed competent person to state that a stage of work is compliant with the building development approval.
Business Queensland describes building certification as independently checking and approving building work against the safety, health, amenity and sustainability standards set by legislation and building codes. Form 16 is the certificate that carries one stage of that. It is not a general site note - the form asks for the stage, property, building or structure, components certified, basis of certification, reference documents, certifier details, inspector details, signature, inspection date and certificate date, and each block has to match the actual inspection and approval.
Who can complete and sign Form 16?
A building certifier for the work, another building certifier, or the appointed competent person for inspection. That is what the Form 16 appendix says, and Business Queensland guidance adds that a certifier may use a competent person to provide inspection help for aspects of a stage only after deciding the person is competent for that help.
For single detached class 1a buildings and class 10 buildings or structures, the appendix also notes restrictions around who can sign certificates for certain stages, including foundation or excavation, footings, slab and final stage work. On those jobs Form 16 is not a hand-off to whoever is nearby. Check the official form and the building approval before signing.
Before you fill anything, confirm you are the relevant building certifier, another building certifier, or an appointed competent person for this inspection help; that the stage on the certificate matches the inspection requested; that the work inspected matches the components certified; and that licence, registration, company and contact details are current.
Where Form 16 sits in the job
Business Queensland lists mandatory inspection stages for new houses including excavation, footings, slab, frame and final. It also notes that class 10 buildings and structures other than swimming pools have the final stage as the only mandatory stage under the Building Regulation 2021, though a building approval may list more.
So Form 16 usually sits between a finished stage and the next part of the job, with the builder wanting to move and the certifier needing the record. It also sits beside other certificates. The official appendix says the inspecting person may rely on aspect certificates from appointed competent persons, such as Form 12, or from QBCC licensees, such as Form 43. At the end of the job the certifier issues Form 21. The QLD building certificates workflow maps how the set fits together.
Filling the certificate section by section
Before you leave site, have the approval number, certifier reference, property details, inspection request, photos, drawings, reports and related certificates in front of you.
Stage of building work
Name the stage in plain terms, aligned to the approval and the Building Regulation language. "Frame stage" or "final stage" may be enough on a small job. On a larger job you may need a location, area, building, unit or stage split. Avoid wording that makes the certificate look bigger than the inspection - if it covered a defined part of the job, say so.
Property and building details
The property description should identify the land subject to the application. Do not rely on the job booking address. Check street address, suburb, state, postcode, lot and plan, and local government area against the approval or title details.
For the building or structure, include the class. "Class 1a dwelling and attached Class 10a garage" tells the story better than "new house". Where a job has multiple structures, use wording that ties the certificate to the right one.
Components certified
This is the section that matters most. The official form asks you to clearly describe the extent of work covered by the certificate. Write it so a builder, certifier, council officer or future inspector understands what you inspected without ringing you.
"Frame stage to single-storey dwelling, excluding detached garage" is clearer than "frame". "Footing reinforcement to retaining wall along western boundary" is clearer than "footings".
Basis of certification
The form asks for the basis for giving the certificate and the extent to which tests, specifications, rules, standards, codes of practice or other publications were relied upon.
Name the plans, engineering drawings, inspection notes, test results, specifications or related certificates that supported the decision. It does not need to be an essay, but it should stand on its own.
Reference documentation
Use document numbers, drawing revisions, dates, report references and certificate names where available. Where you relied on a Form 12 or a Form 43, include enough detail to identify that certificate later.
Certifier and inspector details
Check the building certifier reference number and building development approval number before you send - these are easy to copy from the wrong job. The inspector block needs the correct name, company, contact details, postal address, licence class or registration type where applicable, and licence or registration number where applicable. Saved details in Tradie Forms cut the repeat typing, but the final check belongs to the person issuing the certificate.
Where Form 16 goes wrong
The recurring faults are all wording and role faults, not layout faults. The stage gets named too loosely, so "stage inspection" replaces the actual stage of work. The component wording covers the whole job when the inspection covered part of it. The basis is thin, with no reference to the tests, plans, standards, codes, reports or certificates relied on. The wrong person signs, because Form 16 gets treated as a generic builder sign-off. And the inspection date and certificate date - two separate fields - get carried across from an old PDF.
Tradie Forms maps your entries onto the official layout and flags missing required fields. It does not decide whether the stage complies, whether you are properly appointed, or whether the certifier can rely on the certificate. That stays with the inspecting person and the building certifier.
Next steps
Start the QLD Form 16 inspection certificate when the stage inspection is ready to document, then follow the filing steps in the Form 16 record keeping guide.
If the record is an aspect certificate rather than a stage certificate, compare the Form 12 aspect inspection guide and the Form 43 QBCC licensee aspect certificate guide before you prepare the wrong paperwork.
