There has been a 29.4% increase in planning permissions granted in July, August and September compared to the same period last year.
It is the highest number of approvals since the fourth quarter of 2023, according to the Central Statistics Office.
The total number of homes granted planning in the third quarter of this year rose from 8,611 to 11,142 compared to same time in 2024.
The latest data from the CSO will be viewed as a positive indicator for the future supply of housing.
The number of apartments approved was up 51.2% from 3,318 to 5,016 while the number of house approvals increased 15.7% from 5,293 to 6,126.
Planning permissions in Dublin rose by 47.9% as the number of apartments approved more than doubled from 1,293 units to 2,792.
In contrast, the number of houses in the capital granted planning fell 57.5% from 824 units to 350.
The CSO warns that figures from one quarter to the next "can vary significantly" if several large developments are approved at the same time.
