DUBLIN city councillors are seeking to protect five Moore Street buildings associated with the 1916 Rising.
The five include one occupied by Michael Collins during the rebellion.
People Before Profit councillor John Lyons proposed at Monday night's council meeting that the buildings be added to the register of protected properties based on their significance to the period.
Management advised the public representatives that because planning permission was granted at some of the sites, the council could leave itself open to compensation claims if the buildings were given protected status.
Mr Lyons described management's recommendation as "very disappointing".
"The level of indifference to our urban history and heritage from some in Dublin City Council is frankly quite shocking," he said.
Councillors passed the motion unanimously despite the warning from city managers.
A report will now have to be prepared for the council to assess the suitability of the buildings before they can be added to the protected list.
Numbers 14 to 17 Moore Street are protected under national monument status.
An additional 13 buildings have been recommended for inclusion on the list by experts at the Department of Heritage's National Inventory of Architectural Heritage.
Buildings suggested for protection at Monday's meeting were included in the 2012 Myles Battlefield report. They are:
l The O'Brien's Mineral Water Building in Henry Place that was occupied by volunteers.
l The White House, Henry Place, which was also used by the fighters, including Michael Collins.
l Hanlon's, 20-21 Moore Street, where the surrender order was accepted by volunteers after consultation with Thomas Clarke, Joseph Plunkett, Michael Collins and Sean MacDiarmada.
l 10 Moore Street and the O'Brien's Bottling Stores.
"The whole terrace tells the story," Mr Lyons told the meeting.
Labour councillor Dermot Lacey also supported the motion, but voiced a note of caution about the development of the city in the coming years.
"It's also important that the Dublin of the future isn't just one big museum," he said.
The area of Moore Street was subject to an evaluation before the provision of planning permission to Chartered Land to build a shopping complex on the street in 2010.
Last year, a land-swap deal that would have seen two buildings owned by the council transferred to the developer in exchange for 14-17 Moore Street was rejected by elected representatives.
Under the terms of the deal, the company would have had to commit to developing a national museum there in time for next year's centenary celebrations. Several campaigns have sought to secure the preservation of the entire terrace.
