Concern has been expressed about whether the deadline to set up a short-term letting register will be met.
Under a European Union regulation, anyone offering paid accommodation for up to and including 21 nights will be required to register each unit with Fáilte Ireland.
The deadline for the introduction of the register is 20 May.
The Irish Self-Catering Federation said that many operators do not have short-term rental planning permission, which is needed to join the register.
Chief Executive Máire Ní Mhurchu said that this was a retrospective requirement, but it has not been simple to secure, as planning requirements can differ, depending on the county.
September – at the end of the summer season – would be a much better time to begin the register, she told RTÉ's Today with David McCullagh.

Threshold said that too many homes were being used as short-term tourist lets when housing shortages were worsening.
The housing charity’s Chief Executive, John Mark McCafferty, said that a planning structure to implement the change should have been put in place.
He told the same programme that operators should have been informed that permission was required before they began renting their properties.
"Any lack of urgency is at the Government’s hands," Mr McCafferty said, as the EU had given due notice about the change.
He also said that there had been a lack of enforcement and policing in the short-term letting sector at local authority level.
Mr McCafferty said that it would be ironic if Ireland was fined by the EU for implementing the register by the deadline as it is in the Government’s power to ensure that a proper framework is in place.
"This is how we get quality data for the sector at a time when supply is absolutely key," he added.
All councils zoning land for housing, committee to hear
All 31 local authorities have begun work on zoning more land for housing as requested by the Minister for Housing.
Fourteen councils have varied their development plans to provide more serviced or easily serviced land for housing.
In an update to the Oireachtas Committee on Infrastructure and National Development Plan Delivery, the County and City Management Association will say that a further 10 local authorities will have completed some of the work by June.
It will also say that all 31 councils will have some part of the variations completed by the end of this year.
Minister for Housing James Browne wrote to councils in July 2025 requiring them to rezone more land for housing in order to reach increased targets.
He has since warned local authorities that they have not been making sufficient progress.
In its opening statement to the committee, the association will say that when all planned rezonings are complete, the process will yield approximately 15,102 hectares of residentially zoned land in development plans nationally.
It will say that based on an average density of 35 units per hectare, this represents a total residential capacity of approximately 528,000 units, sufficient to house over 1.1 million people - at an occupation rate of 2.1 persons per unit.
The association will warn that rezoning alone will not deliver housing.
"The constraint on the realisation of these lands as actual homes will be infrastructure - particularly water and wastewater services and transport connectivity.
"Many of the lands being brought forward through the variation process are serviceable in principle, but their activation is contingent on capital investment by Uisce Éireann, ESB Networks, BGE (Bord Gáis Energy) and other utilities and, in respect of transport, by local authorities acting as road authorities.
"The alignment between planning timelines and infrastructure investment timelines is an area requiring sustained Governmental attention," it will say.
