The Silent Lapse: For Every Developer Who Asks for More Time, Twenty Walk Away

In Q1 2026, 218 developers filed extension of duration applications — the formal request to keep an expiring planning permission alive. That number, now above the Covid peak, drew attention as a measure of viability stress.

But extension applications are filed by the developers still fighting. They require proof that substantial works have been carried out. A site that never broke ground often cannot qualify. And even when developers do file, refusal rates spiked to 37% in 2022. They have since eased to 16% in 2025, but that is still double the pre-2022 norm.

At most one in twenty developers with expiring permissions files an extension — and the true rate may be higher, since the denominator includes permissions that were built but never linked to a building control record. The rest let the permission lapse. With the viability ceiling suppressing margins, the traditional escape route — selling the permitted site to another developer — offers little relief when no buyer can make the numbers work either. Either way, the planning system's output is expiring faster than it is being replaced.

How large is the expiring cohort?

2021 was a record year for residential new-build permissions in Ireland. Councils granted 9,404, a third above the lockdown-suppressed 6,987 in 2020. The post-lockdown backlog clearing was concentrated: September 2020 alone produced 1,121 grants, double the pre-lockdown monthly average. That administrative bottleneck created an artificial cliff edge: a concentration of permissions all expiring in the same quarter, five years later.

Those permissions carry a standard five-year duration. The September 2020 batch expires in September 2025. The 2021 record cohort expires across 2026.

The 2020-2021 combined cohort is 16,391 residential new-build grants, 15% larger than the 2018-2019 cohort (14,242) that preceded it.

What does the expiry calendar look like?

Every quarter of 2026 exceeds 2,000 permission expiries. Q3 2026 is the peak at 2,605. The wave does not normalise until late 2027, with Q1 2027 still at 2,401.

The Q2-to-Q3 2025 swing is 134%. That sharp step reflects the post-lockdown backlog: councils cleared a dam of applications in Q3 2020, and those decisions are now expiring simultaneously. The sustained plateau across 2026 — all four quarters above 2,000 — is the 2021 record cohort hitting its five-year mark.

The two years produce distinct sub-waves. 2020 granted fewer permissions (6,987) but with a higher average unit count (6.6 per application where unit data is recorded) — the SHD era of large apartment schemes. While the Planning and Development (Amendment) Act 2025 clarified that SHD permissions can apply for extensions, their scale makes them the least likely to have met the "substantial works" threshold if the developer ran out of funding before breaking ground. 2021 granted more (9,404) but averaged 3.7 units — predominantly one-off houses and smaller council-level developments. The 2025 expiry wave is fewer permissions with more units each. The 2026 wave is more permissions with fewer units each.

Is the pipeline replacing what's expiring?

Grant volumes fell 25% from 8,605 in 2022 to 6,456 in 2023 and have not recovered (6,243 in 2024, 6,511 in 2025). In 2021, councils granted 9,404. The current pipeline is producing roughly 30% fewer new permissions per year than the number expiring from the peak cohort.

This is not a delivery crisis today. CSO data shows 36,284 new dwellings completed nationally in 2025, the highest since at least 2011. The 2020-2021 record cohort is being delivered — that is where the completion boom comes from. But completions lag grants by two to four years. The grant decline from 2022 onward has not yet reached the completions data. When it does, around 2027-2028, the thinned pipeline will start to show.

An expired permission does not necessarily mean a lost home — the developer can reapply, or may have built under a different mechanism. But the planning system's banked output is being consumed faster than it is being replenished.

Outside Dublin, the median new-build sale price is at or below the approximate €350,000 delivery cost floor estimated by the SCSI. In rural Ireland, 69% of new-build sales in 2025 were below that threshold. The viability ceiling analysis documents this gap in detail. Permissions are expiring into a market where many of them could not have been delivered profitably even if the developer had tried.

Why don't developers extend?

An extension of duration application requires the developer to demonstrate that substantial works have been carried out. A site that never broke ground often cannot qualify. The 2025 Act created a temporary amnesty allowing extensions for uncommenced housing developments, but the application window closed on 1 February 2026. Anyone holding an expiring 2021 permission in Q2 or Q3 2026 missed it.

And the odds of success have shifted.

Between 2018 and 2020, councils refused 3-8% of extension applications. The rate jumped to 11.4% in 2021 even before the main spike. The Planning and Development (Amendment) Act 2021 introduced a temporary Covid relief extension mechanism (Section 42B) that ran until December 2023, but the spike in standard EOD refusals suggests councils were simultaneously applying stricter scrutiny to non-relief extensions. The rate has since come down but remains elevated.

January 2026 produced 148 residential EOD filings, the highest single month on record. The 2021 cohort — the largest on record at 9,404 grants — is hitting its five-year mark across 2026. The EOD surge documented in the viability ceiling analysis is the expiry clock running out.

Meath is the outlier. With 129 residential EODs against 457 residential new-build grants from 2020-2021, it has a 28.2% extension rate, roughly four times the national average. In most councils, the rate is below 5%. Meath's commuter-belt self-builders — many holding one-off rural permissions on unsewered sites where Covid-era supply chain delays and pyrite remediation pushed timelines beyond five years — are the exception: they want to build and are actively fighting for time. The viability ceiling analysis documents this pattern in detail.

For many developers, letting a permission die is a quiet financial loss. But for those holding zoned land, the expiry wave is about to collide with a tax liability.

Who is being taxed on permissions they're about to lose?

Seven hundred and thirty-one residential new-build grants on RZLT-liable land expire in the next twelve months, representing 5,741 permitted housing units. These developers are paying 3% of site value annually on land where they hold a permission the market could not activate and the clock is about to run out.

The RZLT was designed to penalise landowners who sit on zoned land without developing. On these sites, the developers obtained planning permission and could not make the economics work within the statutory window. The permission is about to expire while the tax continues to accrue. Part 3 of this series tracks what happens to these sites — and who ends up holding the land.

Which councils deteriorated most?

Each bar shows the change in activation rate from the 2016-2019 baseline to the 2020-2021 cohort, measured only in councils where the building control linkage data is reliable.

Louth and Kildare are commuter-belt counties where sale prices sit at or near the viability ceiling. Limerick and Roscommon face a similar squeeze from the cost side. Cork County's -2.4pp decline is notable given its volume (1,693 grants) — the mix of one-offs and developer schemes averages down. The rural western councils — Mayo, Galway, Kerry, Cavan, Leitrim — show no deterioration at all; several improved.

What does this mean before you submit a scheme?

The expiry wave changes the competitive landscape for anyone holding or seeking a residential permission.

If you hold a 2020-2021 permission approaching expiry, the extension data says your odds of getting more time depend heavily on where you are. Meath developers are extending at 28%. Most councils are below 5%. The refusal rate has come down from 37% (2022) to 16% (2025), but filing is still not a formality — and the substantial works requirement may disqualify you if your site never broke ground.

If you are applying for a new permission, the contracting pipeline means less competition from existing permissions in your area. As 2021-era grants lapse, sites that were locked up by unactivated permissions become available again. The gap between permission expiry and new application is where opportunity sits.

If you are advising on RZLT exposure, the collision between tax liability and permission expiry is sharpest over the next twelve months. 731 grants on RZLT land are approaching expiry. The three available paths — extension (if eligible), fresh application, or letting the permission lapse while the 3% annual charge continues — each carry different cost and timeline profiles. The delivery cost benchmarks have shifted since the 2020-2021 economics these permissions were based on.

What the data does and doesn't show about where this leads

The logical conclusion from these two articles — that private delivery is structurally broken outside Dublin and the State will be forced to step in — is plausible but not yet measurable in the planning data.

What the data does show: of the residential permissions that expired in 2024-2025, only 3.1% of sites have had a new application submitted. The other 97% remain dormant. This is not cyclical churn where permissions expire and get resubmitted under better conditions. It looks more like sustained abandonment.

What the data does not show: whether those sites are being sold, whether AHBs or local authorities are acquiring them, or whether developers are pivoting to turnkey deals with the State. Social housing and Part V indicators are effectively invisible in the planning register (below 0.1% of proposal text). The secondary market for permitted sites — frozen or functioning — leaves no trace in the data Archa collects.

What the data contradicts: the assumption that planning activity is concentrating toward Dublin. Dublin's share of new-build PPR sales has fallen from 43.5% to 26.3% over the period. Rural Ireland's share of planning activity has grown, not shrunk. The viability ceiling is real, but it has not yet translated into the geographic collapse that the economics might predict.

The honest reading is that the planning system's output is evaporating and the replacement pipeline has thinned. Whether the State fills the gap, or whether these sites simply sit vacant, is a policy question the planning data cannot answer.
