Housing supply pressures remain acute in parts of the Shannonside region with some of the lowest levels of construction activity in the state, according to the latest GeoDirectory Residential Buildings Report.
While Ireland's total residential stock rose to just over 2.2 million dwellings by the end of 2025, counties such as Longford, Leitrim and Roscommon continue to see limited new supply, despite rising demand and increasing house prices.
Longford recorded the weakest construction activity in the country, with just 147 buildings under construction at the end of the fourth quarter of 2025.
Leitrim followed closely with 156 buildings under construction, while Roscommon accounted for 348 buildings, or 1.2 per cent of the national total.
The commencements data paints a similarly stark picture.
In the 12 months to December 2025, just 82 housing units were commenced in Longford and 52 in Leitrim - the lowest figures recorded nationwide.
Roscommon fared marginally better with 111 commencements, but still ranked among the weakest-performing counties.
Despite low levels of new building, vacancy rates remain well above the national average locally.
Leitrim recorded the highest vacancy rate in the country at 11.7 per cent, more than three times the State average of 3.7 per cent.
Roscommon followed closely with a vacancy rate of 10.1 per cent, while Longford's vacancy rate stood at 7.1 per cent, still significantly above the national figure.
