Lapsed or Expired Building Approvals on a Brisbane Property: What Sellers Should Disclose and How to Fix It

A lapsed approval is not the same as no approval. It is a half-finished paper trail council can see, and it almost always surfaces in buyer due diligence. Here is how to deal with it properly before you list.

Of all the title and council issues that derail a Brisbane sale, a lapsed or expired building approval is one of the most common and the most misunderstood. Sellers often confuse it with the more familiar problem of unapproved works (where approval was never sought). It is a different situation, with different disclosure requirements, a different fix, and a different impact on the contract. Approval was issued. The paper trail exists. Brisbane City Council can see it on their system. But the approval itself is no longer live, and what that means for the sale depends on exactly how it lapsed and how far the work progressed before it did.

Across Brisbane's inner east, where character homes have been added to, extended, lifted, raised, and reclad through multiple ownership cycles, lapsed approvals turn up in PD Online searches with surprising frequency. A new deck that received approval in 2017 but was never finalised with a Form 16. A bathroom renovation that lapsed when the original builder dissolved. A pool excavation that was approved, started, paused for a divorce, and never re-engaged. Each of these is a discoverable record that any competent buyer's solicitor will pick up. Knowing what is in the file before you list is the only way to control how the buyer hears about it.

What lapsed and expired actually mean under Queensland law

Building approvals in Queensland are issued under the Building Act 1975 and the Building Regulation 2021. Every approval has a defined currency period. For most residential building work, the approval lapses if the work has not been started within two years of the approval being given, or if it has been started but not completed within four years (or whatever shorter or longer period the certifier specified in the conditions). These periods are extendable on application before they expire, but if the deadline passes without an extension being granted, the approval ceases to have any legal effect.

Lapsing is not just an administrative inconvenience. Once an approval has lapsed, any further work on that project cannot rely on it. If the work was already completed but the final inspection (the Form 16 Certificate of Completion or, for pools, the Form 17) was never issued, the work is in legal limbo: physically built, paper-trail incomplete, and not formally certified as compliant with the Building Code of Australia at the time of approval. In practice, this looks identical to unapproved work from a council records standpoint, but the cause is different and so are the available remedies.

There is also the related situation of expired conditions. Some approvals are subject to development conditions, often issued by Brisbane City Council under the Planning Act 2016, with their own timeframes. A material change of use approval for a granny flat, for example, may have a currency period of four years for the use to commence. If the use was never commenced within that window, the planning approval has lapsed even if the building approval was finalised. This is uncommon but it does happen, particularly with secondary dwellings and home-based business approvals.

The three most common lapse scenarios in Brisbane's inner east

The first and most common scenario is what I would call the unfinalised approval. The work was approved, the builder turned up, the structure was built, but the certifier was never called back for the final inspection. The Form 16 sits unissued. This happens routinely with owner-builder projects, with builders who left the trade, and with renovations where the owner thought the work was done and moved on. The structure is physically complete but the council file shows the approval as open and the work as uncertified.

The second scenario is the abandoned approval. Approval was granted. Work was started or about to start. Then something changed: finance fell through, the contractor went into liquidation, the relationship that funded the renovation ended, or the owners decided not to proceed. Years passed. The approval expired. The remnants of the work may or may not still be on site (footings poured, services roughed in) but nothing has progressed since.

The third scenario is the partially completed approval, where work was approved for a multi-stage project, the first one or two stages were finalised, and the remaining stages never were. The classic example is a multi-room renovation where the kitchen and ensuite were certified but the master bedroom extension or the second bathroom was never finalised. The overall approval is closed against the certified stages and open against the rest.

How a lapsed approval surfaces during a sale

Buyers' solicitors conducting standard pre-contract searches will routinely order a Brisbane City Council building records search, a planning records search, and a title search. The building records search will show the history of lodged applications, including those that are open, lapsed, certified, or refused. Where an approval is on file but no Form 16 has been issued, the search result will flag this. The same applies to planning approvals that show an unactivated material change of use.

If your contract is already signed when the search surfaces a lapsed approval, you are now in negotiation. The buyer's solicitor will typically ask for either rectification (you fix the file before settlement), an indemnity (you compensate the buyer for the future cost of fixing it), or, in some cases, a price reduction. The leverage at this point sits largely with the buyer. They have a signed contract, a standard cooling-off period or a finance and inspection clause, and an issue to raise. The further into the contract you are when this comes up, the more difficult it becomes to negotiate cleanly.

If you have already done the same search yourself before listing and the issue is disclosed up front, the dynamic is very different. Buyers who are told about a lapsed approval at the point of inspection, with a clear explanation of what it is and what is being done about it, generally factor it into their offer without making it a contract-stage issue. They have committed to the purchase with eyes open. There is no later surprise to renegotiate against.

Your disclosure obligations under the Property Law Act 2023

Since 1 August 2025, every Queensland seller must give the buyer a Form 2 seller disclosure statement before the buyer signs the contract. The Form 2 is prescribed under the Property Law Act 2023 and the Property Law Regulation 2025. It is not optional, and the consequences of giving an incorrect or incomplete Form 2 are serious. The buyer can terminate the contract at any time before settlement and recover their deposit if a required matter was not properly disclosed.

A lapsed or expired building approval is not a tick-box item with a dedicated field on the Form 2, but it sits inside several categories that the form does require. It may be relevant under the show cause notices and enforcement notices section if council has taken any action, under the structural defects and notices section depending on the nature of the work, and under the standard catch-all for material facts about the lot. Most solicitors will recommend that any known approval status issue is either captured in the Form 2 itself or attached to it through the relevant council records, with a brief explanation of the status.

The safe approach for sellers in 2026 is to obtain the council records before instructing your solicitor on the Form 2, hand the records to your solicitor with a written summary of what is open and what you know about why, and let them decide how the disclosure should be structured. This is one of the situations where a small amount of legal advice up front protects you from a much more expensive problem later.

Path one: extend the existing approval (if you still can)

If the original approval has lapsed only recently, or if it is approaching expiry but has not yet lapsed, the cleanest fix is an extension. Building approvals can be extended on application to the certifier who issued the original approval (or to a new certifier if the original one is no longer in practice). The extension application is straightforward where the work has been completed and only the final inspection is outstanding. The certifier attends the site, inspects the works against the approved plans, and issues the Form 16 to finalise the file.

Cost for this path is typically modest, often in the order of $800 to $2,500 for a residential job depending on the complexity of the inspection and any reports or engineering certificates required. Timeline is usually two to six weeks. If your campaign launch is at least six weeks out, an extension and finalisation is the cleanest pre-listing fix for an unfinalised approval and it is the path I recommend most often when the underlying work is sound.

The limitation is that you cannot extend an approval that has been lapsed for longer than the regulations allow. Once the timeframe has passed, the approval is gone and you cannot resurrect it. You are then looking at path two.

Path two: fresh approval for existing work

When the original approval is no longer extendable, the standard fix is to apply for a building approval for existing work, which is essentially the same retrospective approval process used for genuinely unapproved structures. A private building certifier assesses the existing works, in most cases against the standards that applied at the time the work was originally done, although current standards may apply to certain elements such as safety glazing, smoke alarms, or pool fencing.

The application requires drawings of the as-built work, often a structural engineer's certificate confirming the structure is adequate, and any other specialist reports the certifier needs to satisfy themselves the work complies. Cost varies widely with complexity: a simple deck might be $3,000 to $6,000 all in; a full extension with multiple trades might be $8,000 to $20,000 or more. Timeline is generally six to twelve weeks but can blow out if engineering or planning issues emerge during the assessment.

For sellers, the key question is whether you complete this process before listing or disclose the lapsed approval and let the buyer take it on. Both approaches are legitimate. Completing the process before listing produces a cleaner sale and usually a better price, because buyers are not paying both for the property and for the uncertainty of resolving the approval. Disclosing and discounting is simpler but tends to attract bargain hunters and produces lower offers, often more than the cost of the certification.

Path three: remove the work and revert

The third path is narrow but real. If the lapsed approval relates to work that has not been done or that has been partially done and is not progressed, and obtaining fresh approval is impractical or impossible, the cleanest option is to remove the works and restore the property to its previously approved configuration. This is most relevant where the original approval was for an extension that was started, paused, and abandoned, and the partial structure on site cannot reasonably be either completed or approved as built.

Removing partial works has its own cost and its own approval implications (demolition itself can require approval depending on scope). The advantage is that it eliminates the disclosure issue entirely. The council file may still show the historical lapsed approval, but there is no longer anything on the lot that requires certification. The buyer is buying a property whose physical condition matches its approved status.

What it costs you on price if you do nothing

The market discount on a Brisbane property with a known lapsed approval that has not been resolved varies significantly with the type of work involved and the buyer pool. For a small structure like a deck or a carport where the resolution cost is well-defined, the discount is generally close to the cost of the resolution plus a modest uncertainty premium. For a larger structure like a major extension where the rectification cost is harder to bound, the discount is often two to three times the actual cost, because buyers price in the worst plausible scenario rather than the expected one.

The pattern I see most often in Brisbane's inner east is that the cost of resolving the issue before listing is two to four thousand dollars and the price impact of not resolving it is somewhere between ten and forty thousand dollars depending on the structure. The maths is rarely close. The only situation where leaving it is the right call is when the rectification path is genuinely uncertain (for example, where the work cannot be approved as built and removal is impractical) and disclosure with a calibrated discount is the cleaner exit.

The pre-listing checklist for an approval status review

Order a Brisbane City Council building records search and planning records search on your property at the start of the pre-listing process. This costs less than a hundred dollars and provides the definitive record of what is on file. If anything in the result is unclear or shows an open application without a corresponding completion certificate, raise it with your solicitor and decide on the resolution path before you brief your agent on the campaign. Get an indicative cost and timeline from a private building certifier for the relevant resolution. Build the resolution cost and timeline into your pre-sale plan so the campaign launch and the certificate issue are aligned. Brief your solicitor on the status so the Form 2 disclosure is accurate.

If you uncover a lapsed approval during this process, the worst response is to do nothing and hope the buyer's searches do not find it. They will. The PD Online system makes it routine for any solicitor to pull a complete building records history. The question is not whether the issue will come to light, but whether it comes to light on your terms, before contract, or on the buyer's terms, after contract, with the leverage on their side.
