That's according to a newly published GeoView Residential Buildings Report.
Speaking on behalf of Geodirectory, who published the report, Dara Keogh said this is a manageable level. He believes it's a sign that Limerick's housing market is operating efficiently.
"Nationally you have (a vacancy rate of) 4.5 and in Limerick you have 4.7," said Keogh. "That's actually down on 2020 when it was 4.8."
"What that means is that the vacancy rate is within the tolerance range but within the lower end of it," he added. "What you'll start to see is pressure on pricing, pressure on the houses that are there. While there's a perception that there's loads of vacancies, there isn't, because for the market to function you need real vacancies."
In February the GeoView Commercial Property Report found that Limerick has one of the country's highest commercial vacancy levels.
16.2% of Limerick's commercial properties were found to be vacant, a rise from 15.6% in 2020 and above the national average of 13.5%.
