A Sinn Féin Private Members' Bill to protect the national monument at Moore Street in Dublin was amended by the Government and passed by 78 votes to 38.
Minister of State Dinny McGinley said the original wording of the proposed legislation contained factual inaccuracies.
The legislation called on the Government to ensure the preservation of houses numbered 14 to 17 Moore Street as a national monument.
Mr McGinley said there was currently no new planning application and that full permission had been granted in 2010 for the development of the site containing the national monument.
He added that the Moore Street monument is protected under existing legislation and an application for consent for proposed works to the national monument were being examined by the Government.
Sinn Féin leader Gerry Adam said there was no justification for giving the go ahead to a development that would demolish the surrounds of a national monument, in favour of the commercial interest of a property developer.
He said there was a moral obligation on the minister to restore and develop the area as a fitting tribute to the heroes of the 1916 Rising.
