Most owners of a landed rebuild think of completion as the day the scaffolding comes down. The building tells a different story. A house is finished when it has been certified as complete — and the certificate is issued on the strength of a paper trail that was either built alongside the house or was not.

This is the part of a project where the difference between a licensed builder and a cheap one becomes visible, and by then it is too late to change either.

TOP and CSC are not the same thing

Two documents get confused constantly, and owners sign contracts without knowing which one they are being promised.

A Temporary Occupation Permit lets you move in. It says the building is safe to occupy while some items remain outstanding. It is temporary in the literal sense — it is granted on the basis that the remaining work will be closed out.

A Certificate of Statutory Completion is the end state. It is issued by the Commissioner of Building Control once the building work has been completed in accordance with the approved plans and the required clearances from the relevant authorities are in place. It is the document that says the project is done, in the eyes of the law rather than in the eyes of the owner.

Both are applied for by your Qualified Person, not by you and not by the builder. The QP submits; the builder makes the submission possible by having actually built what was approved and by holding the records to prove it.

Some projects go straight to CSC without a TOP. Which route applies to yours is a question for your QP early, not a detail to discover at the end, because it changes when you can realistically move in.

The certificate is only as good as the record

The single most common cause of a slow closeout is not defective work. It is missing evidence of work that was done perfectly well.

Building work gets covered up. Reinforcement is cast into concrete, waterproofing disappears under screed, services vanish into walls. If nobody recorded and no one inspected at the moment those things were open, the fact that they were done correctly becomes an assertion rather than a record — and an assertion is not what a submission runs on.

This is why the inspection regime during construction is not bureaucracy for its own sake. On a project requiring supervision and filings, the inspections happen at defined stages precisely because those stages are the last moment anything is visible. Miss one and the choice at the end is opening work up again or arguing.

The practical consequence for an owner is simple. Ask, during construction and not after it, whether the record is being kept — inspection records at each stage, material and test records where the design calls for them, and the as-built information showing what was actually built where the approved drawing and the site diverged.

Where landed rebuilds get caught

A few things account for most of the delay we see, and all of them are decisions made months earlier.

What was built is not what was approved. A wall moved during construction, a window enlarged, a level adjusted because it worked better on site. Every one of these is fine if it is picked up and regularised through the QP while the project is running. Left unaddressed, the completion submission describes a building that does not exist and the discrepancy surfaces at the worst possible moment.

Work outside the approval. Structures added at the end — a shelter, a deck, an enclosure — are building work whether or not they feel like it, and they can sit outside what was approved. We have written separately about what unapproved works from a previous owner do to a property; the mechanism is the same when the works are your own and recent.

Boundary and neighbour conditions. Anything agreed with a neighbour during the works — access, a party wall condition, protection of an adjoining property — needs to end in the state the approvals assume, not in the state that was convenient during construction.

Services and their clearances. The systems in a house have their own sign-offs, and they are not interchangeable with the building sign-off. They run on their own timelines and they cannot be compressed at the end by wanting them faster.

What we do so the closeout is not a project of its own

We are a BCA General Builder Class 2 (GB2) licensed builder, and the licence carries obligations that exist for exactly this reason — the ability to demonstrate what was built, by whom and to what standard.

In practice that means the record is assembled as the work happens rather than reconstructed afterwards: inspections called at the right stage rather than the convenient one, deviations raised with the QP when they arise rather than filed away, and the as-built information kept current instead of drawn from memory at the end.

It is unglamorous, and it is invisible in a quotation. It is also the difference between a completion that takes weeks and one that takes a great deal longer.

Questions worth asking before you sign

• Who is applying for TOP or CSC, and is that person appointed? The QP does it. Confirm the appointment exists rather than assuming it is included.
• Is the QP's fee inside the builder's price or outside it? This is a routine source of surprise. We have set out what is and is not included separately.
• What happens to the retention, and when? Completion and the release of money should be tied to defined events, not to goodwill.
• Who closes out the deviations? There will be some. The question is whether they are tracked and regularised as they occur.
• What records will I receive at handover? As-built information and the inspection and test records are the house's history. They matter again when you sell, or when the next owner's surveyor asks.

Common questions

Can I move in before CSC?
Where a Temporary Occupation Permit is granted, yes — that is what it is for. The outstanding items still have to be closed out afterwards.

How long does the closeout take?
It depends entirely on how complete the record is and whether what was built matches what was approved. A project where those two things were managed throughout closes out quickly. One where they were not can take far longer, and no builder can honestly quote a duration for it in advance.

Who is responsible if the works do not match the approved plans?
Practically, it becomes the owner's problem, because it is the owner's property and the owner's submission. That is the reason to appoint a licensed builder and an engaged QP rather than to treat both as paperwork.

Do small A&A works need this?
The scope decides it, not the size of the budget. We cover what we check on a small A&A separately — the first question is always what the works actually are in regulatory terms.
