The Residential Tenancies Bill has been signed into law by President Catherine Connolly.
It is the Government's intention that the bill, which will drastically reform rules around renting in Ireland, will come into effect on Sunday, 1 March.
Opposition TDs argue that the legislation unfairly targets renters, claiming rental costs will skyrocket in the short-term.
However, the Government says the bill will strengthen tenants rights with security of tenure while driving investment.
Earlier this month, the bill passed the final stage in the Dáil, passing with 79 votes in favour and 70 votes against following a heated debate in the chamber.
And last week, it passed its final stage in the Seanad.
It was strongly opposed at all stages by the Opposition.
In all, there were 27 amendments tabled in the Seanad and 69 tabled in the Dáil.
However, the Government rejected all of the proposed amendments in both the Seanad and Dáil.
Minister for Housing James Browne today welcomed the enactment of the bill, saying it will provide greater certainty and stability for tenants, and increase the number of rental homes available.
He added: "It is also important that we balance a need for far stronger tenants' rights with the urgent need to grow the supply of rental homes available. This includes attracting more landlords of all sizes and retain existing landords who are providing homes to rent for people and families. This act provides certainty, as well as robust policy conditions for that sustained increase in supply."
However, Social Democrats TD Rory Hearne called for the Government to pause the introduction of the measures in light of the latest Rental Report by Daft.ie.
The report showed that market rents nationally rose by 4.4% during 2025.
Speaking outside Leinster House today, he said: "The Daft.ie report should be an absolute signal that the measures coming in to allow rents rise even higher should not happen.
"How can the Government justify, when we see these rents, to bring in measures that will allow market rents go even higher?
"It shows this Government is utterly out of touch with what is going on for people across this country."
Labour Party Spokesperson on Housing Conor Sheehan said the consequences of the Residential Tenancies Bill being signed into law will be "dire" for renters.
"The bottom line is simple. Renters trapped in Ireland's dysfunctional housing market will pay the price for what this Government has done," he said.
"Instead of freezing rents and bringing them down, Minister Browne’s rent hike will cause rents to go up by at least 10% because of the so-called market reset mechanism," he added.
