Dublin will need at least 35,000 homes to be built over the next four years, according to the Society of Chartered Surveyors.
A new report by the society says there are more than 2,000 hectares of rezoned land in Dublin, which could deliver up to 100,000 houses.
However, planning permission is available for just 26,000 units.
Conor O'Donovan from the Society of Chartered Surveyors says building has stalled since the financial crash.
He said: "In '06 we built 90,000 units, last year we built just 8,000 units across the country.
"So we need to get back to the stage where there is a more sustainable level of activity in the property market, where people have the confidence to purchase, where developing finance is available to people to build homes, and where there is more people going into the market, buying land, buying sites to build the houses and supply the market."
