The Oireachtas Committee on Enterprise, Tourism and Employment has written to the Minister for Housing James Browne amid concerns over the delay in introducing a new register for short-term lets.
The register - which is intended to force more Airbnb style properties into long-term use to help alleviate the housing crisis - had been earmarked to be operational from 20 May.
However, there are now concerns it will not be operational for the forthcoming tourist season with legislation underpinning the measure still being drafted.
"Rural communities that depend on heavily on tourism income have been left in limbo which is deeply unfair," said committee chair, Fianna Fáil Cork East TD James O'Connor.
The Department of Housing must bring forward a National Planning Statement and the Department of Enterprise and Tourism must progress a Short-Term Letting and Tourism Bill before the register can come into effect.
However, negotiations are ongoing between the two departments to find a solution - with the Department of Enterprise said to believe there is much more work to do before the what was initially announced in Februrary can be implemented.
The Oireachtas Committee on Enterprise met in private earlier, with TDs saying there was an urgency for Minister Browne to clarify the status of the National Planning Statement.
The committee has now written to the Minister, saying publication of the statement is necessary for it to carry out pre-legislative scrutiny of the measure.
Towns with a population below 20,000 are exempt from the planned rules.
But TDs representing constituencies reliant on tourism are still concerned about the proposals.
