Practical Completion and Handover in QLD Residential Construction
In QLD a builder reaches practical completion when the work is done apart from minor defects or omissions. Where the owner claims defects, the builder hands over a defects document under Schedule 1B.
What it is
Practical completion is the point in a Queensland residential build where the work is substantially performed and the home can be handed over to the owner. It is defined in Schedule 1B of the Queensland Building and Construction Commission Act 1991, and the regulated contract the parties signed usually restates that definition. Once practical completion is reached, the builder issues a notice of practical completion, the owner pays the final progress claim and the defects liability period starts.
It is not the same as "all finished" or "every snag closed". A build can be at practical completion with a punch list still open, as long as the items left over are minor and do not stop the owner using the home for the purpose it was built for.
What Schedule 1B actually says
The definition lives in section 1 of Schedule 1B of the QBCC Act. Practical completion is the day the subject work is completed:
- in compliance with the contract, including all plans and specifications and all statutory requirements applying to the work
- without any defects or omissions, other than minor defects or minor omissions that will not unreasonably affect occupation
- where the owner claims minor defects or minor omissions, on the day the builder gives the owner a defects document for them
That is the whole test. Note what is not in it. Practical completion does not require a certificate of occupancy or a Form 21 final inspection certificate. Those belong to the building approval pathway under the Building Act 1975 and are a separate question about lawful occupation, not about whether the contract has reached practical completion.
The defects document matters. Where the owner says minor items remain, practical completion is not reached until the builder hands over a defects document. Under the Schedule 1B definition that document lists the minor defects and omissions both sides agree exist, sets a time to fix them and records any items the owner claims but the builder disputes. The builder signs it. Get the defects document right on the day and the practical completion date is clean.
Substantial performance in practice
A defect or omission is minor if it does not prevent the owner from reasonably occupying and using the home. A missing tap washer is minor. A leaking shower waste is not. A bedroom door that needs adjustment is minor. A bedroom door that will not close is not. The QBCC and QCAT have long held that the test is functional, not cosmetic perfection.
Substantial performance also means the contracted scope is built. Walls, roof, services, fitout, finishes and external works listed in the contract have been carried out. Variations have been priced and signed. Provisional sums have been adjusted. Prime cost items have been supplied at the values agreed.
Form 21 and lawful occupation
The Form 21 final inspection certificate is real and it matters, but it is a Building Act 1975 document, not part of the practical completion definition. The building certifier, not the builder, issues the Form 21 under sections 98 and 99 of the Building Act once the final inspection passes. A Form 21 cannot be issued unless every required stage inspection has been signed off, the plumbing final has been done by the Form 4 or Form 9 pathway and any pool, energy efficiency or termite management documents are on file.
A home can be at practical completion under the contract before the Form 21 is in hand, and it can have a Form 21 while contractual defects are still being closed out. Keep the two ideas separate. Practical completion is a contract milestone. The Form 21 is an approval milestone. A clean handover lines both up, but they are decided under different laws.
What handover should include
Handover is the day the builder gives the owner control of the home. A clean handover in QLD usually includes:
- Notice of practical completion in writing with the date
- Final progress claim invoice
- The signed defects document if the owner has claimed minor items
- Form 21 final inspection certificate
- Form 16s for inspections carried out by competent persons (waterproofing, termite, structural)
- Plumbing compliance documentation (Form 4 or Form 9)
- Electrical safety paperwork covering the connected work
- Manufacturer warranties for installed equipment such as the hot water unit, oven, cooktop, rangehood, air conditioning and alarm
- Operation and maintenance information for those items
- Keys, remotes, alarm codes and any letterbox key
- The QBCC home warranty insurance notice if not already provided
Walk the home with the owner and record a defects list. Date it. Sign it. Give the owner a copy. That list becomes the start of the defects liability period.
Defects liability period and statutory warranties
The defects liability period on a QBCC residential contract is typically 12 months from practical completion for general defects. This is a contract period during which the builder returns to fix items on the handover list.
The statutory warranties under Schedule 1B are separate and run longer. Under section 29 of Schedule 1B the warranty period is six years for a breach that results in a structural defect and one year for any other case. Section 29(3) runs that period from completion of the work, not from a certificate or an inspection. Section 29(2) adds a tail: if a breach becomes apparent in the last six months of the warranty period, the owner has a further six months to start proceedings.
During the defects liability period the builder has to attend and fix items that fall inside the warranty. The owner has to give the builder reasonable access. If a dispute starts, the QBCC early dispute resolution pathway is the first stop before QCAT.
Common reasons handover stalls
Most QLD handovers do not stall on the building work. They stall on the paperwork.
- Form 21 cannot be issued because a stage inspection was skipped
- Plumbing compliance has not been lodged with the local council
- The energy efficiency report does not match the as built window schedule
- Termite management notice has not been fixed to the meter box
- The owner has paid the second last claim and is refusing the final until a cosmetic list is cleared
Builders who pre check the document pack two weeks before practical completion avoid almost all of these.
Who signs off practical completion
The builder issues the notice of practical completion. The owner can dispute the date inside the period set by the contract, usually five business days. If the owner does nothing inside that period, practical completion is taken to have been reached on the date in the notice. If the owner disputes, the QBCC dispute pathway or QCAT decides.
The building certifier, not the builder, issues the Form 21. The builder cannot self issue the final inspection certificate.
Practical takeaway for QLD builders
Treat practical completion as the Schedule 1B test, not a Form 21 test. The work is at practical completion when it is done bar minor defects or omissions. Where the owner claims minor items, that day is when you hand over a signed defects document. Book the final building inspection early so the Form 21 is not the thing holding up handover. Chase the plumbing final and the Form 16s. Print the warranty pack. Hand over in person, not by email. Record the defects list on the day. That is the shortest path from last trade on site to final payment cleared.

Schedule 1B section 1 defines practical completion as the day the subject work is completed apart from minor defects or minor omissions that will not unreasonably affect occupation, and where the owner claims minor items, the day the builder gives a defects document. Section 29(3) runs the statutory warranty period (six years structural, one year otherwise) from completion of the work.
