Practical Completion

The house looks finished. The floors are down, appliances are installed and the builder says it is time for Practical Completion. You are ready to move in - but you have also noticed incomplete items and defects.

Practical completion is one of the most important contractual milestones in the entire build. It affects payment, possession, defects and the transition from construction to occupation.

Practical Completion does not mean absolute perfection

Practical completion is a contractual milestone. In broad terms, it usually means the works have reached the stage defined by the contract at which the home is substantially complete and can be used for its intended purpose, subject to permitted minor defects or omissions.

A newly built home can therefore reach practical completion even though a defects list still exists. The exact definition in your contract matters.

Why Practical Completion matters

Practical Completion can trigger several consequences at once: the final or near-final progress payment, handover, commencement of a contractual defects period, changes to insurance responsibilities and the point from which some contractual rights are calculated.

Because so much can turn on this milestone, do not treat the practical completion notice as merely an invitation to collect the keys.

The builder's notice is the start of a process

Your contract may require the builder to give notice that Practical Completion has been reached and may provide a process for inspection, identifying defects and dealing with disagreement.

Read the procedure before the end of the build. The time allowed to inspect or respond can be short.

Inspect systematically

Walk through the home methodically. Compare what has been built with the plans, specifications and selections. Record defects and incomplete items clearly by room or location.

Consider an independent building consultant if you do not have the technical expertise to assess workmanship or compliance.

Separate defects from preferences

A defect is not simply something you do not like. The question is whether the work complies with the contract, plans, specifications, applicable standards and legal requirements.

Likewise, a minor cosmetic defect does not necessarily prevent Practical Completion. The contractual definition and seriousness of the item matter.

Final payment and leverage

The final payment is often substantial. Before paying, understand what contractual event makes it due, what documentation must be supplied and how unresolved defects are treated.

Do not assume you can withhold the entire final payment because any defect exists. Equally, do not assume that an invoice means every contractual requirement has been satisfied.

Keys, possession and handover

The timing of possession and release of keys is usually linked to the contract and payment process. Avoid creating a confrontation at the final moment by understanding the handover machinery before Practical Completion is reached.

Handover documents

Depending on the project, handover may involve certificates, warranties, manuals, keys, remotes, approvals and other records. Keep these documents together with the signed contract and completion records.

The defects liability or maintenance period

Many contracts provide a post-completion period during which listed defects can be notified and addressed. This contractual process is useful, but it is not necessarily the limit of every right a homeowner may have.

Keep a written list, report issues promptly and allow the builder reasonable access to inspect and rectify where appropriate.

Questions to ask before signing

How does the contract define Practical Completion?

Who decides whether Practical Completion has been reached?

What notice and inspection process applies?

What defects can remain at Practical Completion?

When does final payment become due?

When are keys and possession released?

What documents must be provided at handover?

How long is the contractual defects or maintenance period?

The key lesson

Practical Completion is not simply the day the house looks finished. It is a legal and commercial milestone. Understanding the definition and process before signing helps prevent the final stage of an exciting project becoming an avoidable dispute.

Before You Sign

This guide provides general educational information for South Australian homeowners. It is not personalised legal advice. The effect of any issue depends on the wording of your own contract, schedules, Special Conditions, plans, specifications and the facts of the project.

A good builder and a well-understood contract should work together. Before committing to one of the largest financial transactions you may ever undertake, consider having the actual contract reviewed so you understand the obligations, notice requirements and consequences before they are tested on site.
