New Planning Rules Restrict Short-Term Lets in Irish Cities Over 20,000 Population as Airbnb Crackdown Takes Hold
New national planning regulations are being implemented across Ireland that will effectively prohibit new planning permissions for short-term letting in cities with populations exceeding 20,000, in a significant tightening of the rules governing platforms such as Airbnb and Vrbo. The regulations, which apply to Dublin, Cork, Limerick, Galway, and Waterford, are designed to return properties currently used for tourist accommodation to the long-term rental market. Existing operators of unauthorised short-term lets have been given a grace period until the end of 2026 to regularise their arrangements.
Background
The growth of short-term letting platforms in Ireland over the past decade has been dramatic. At their peak, platforms such as Airbnb listed tens of thousands of properties across the country, with Dublin, Galway, and Kerry among the most popular destinations. For property owners, the economics of short-term letting have often been compelling: nightly rates for tourist accommodation can generate significantly higher returns than long-term residential rents, particularly in city centres and popular tourist areas.
The consequences for the long-term rental market have been well documented. Properties removed from the long-term rental pool reduce the supply available to workers, students, and families, putting upward pressure on rents and making it harder for people to find affordable accommodation. Research commissioned by the Department of Housing estimated that at the height of the short-term letting boom, several thousand properties in Dublin alone had been effectively removed from the long-term rental market. In a city already experiencing severe housing pressures, this represented a significant aggravation of an existing problem.
The government's response has been gradual. Initial regulations introduced in 2019 required short-term letting operators in rent pressure zones to obtain planning permission, but enforcement was patchy and the impact on the overall market was limited. The new regulations represent a more comprehensive approach, extending the restrictions to all cities above a certain population threshold and establishing a clearer framework for compliance and enforcement.
Key Developments
The new planning rules, reported by The Irish Times on Wednesday, establish a general presumption against the granting of planning permission for short-term lets in cities with populations over 20,000. This covers Dublin, Cork, Limerick, Galway, and Waterford — the five largest urban centres in the state. The regulations do not apply to rural areas or smaller towns, where short-term letting is regarded as a legitimate and important part of the tourism economy.
Existing operators of short-term lets who do not have the required planning permission have been given a grace period until the end of 2026 to regularise their situation. This can be done either by applying for retrospective planning permission — which, under the new rules, is unlikely to be granted in the affected cities — or by converting the property to long-term residential use. The Department of Housing has indicated that enforcement action against non-compliant operators will begin in January 2027.
The regulations also introduce new requirements for short-term letting platforms to share data with local authorities, enabling more effective monitoring of compliance. This data-sharing requirement has been welcomed by housing advocates, who have long argued that the lack of reliable data on the scale of short-term letting has hampered enforcement efforts.
Why It Matters
The new short-term letting regulations represent one of the most significant interventions in the private rental market in Ireland in recent years. If effectively enforced, they have the potential to return a meaningful number of properties to the long-term rental market in the cities where housing pressure is most acute. The experience of other European cities that have implemented similar restrictions — including Amsterdam, Barcelona, and Lisbon — suggests that the impact on rental supply can be significant, though it is rarely transformative on its own. The key challenge in Ireland, as elsewhere, is enforcement. Local authorities have historically struggled to monitor and enforce planning regulations in the private rental sector, and the new data-sharing requirements from platforms will be essential to making the system work. The grace period until the end of 2026 gives operators time to adjust, but it also means that the full impact of the regulations will not be felt until 2027 at the earliest.
Local Impact
In Dublin, the regulations will have their most significant impact in the city centre, the Docklands, and popular tourist areas such as Temple Bar, Portobello, and the Liberties, where short-term letting has been most prevalent. Dublin City Council has welcomed the new rules and has indicated it will prioritise enforcement in areas where the concentration of short-term lets has been highest. In Cork, the regulations will affect the city centre and the areas around Cork Airport, which has seen significant growth in tourist accommodation in recent years. In Galway, where the short-term letting market has been particularly active during the summer festival season, the regulations will require many operators to make difficult decisions about the future use of their properties. Estate agents in all five cities have reported increased interest from short-term letting operators seeking advice on their options.
What's Next
The grace period for existing unauthorised short-term lets runs until 31 December 2026. From January 2027, local authorities will begin enforcement action against non-compliant operators, with penalties including fines and, in persistent cases, prosecution. The Department of Housing will publish guidance for local authorities on enforcement procedures before the end of the year. A review of the regulations' impact on the rental market is planned for 2028, which will assess whether the restrictions have achieved their intended effect of increasing the supply of long-term rental accommodation in the affected cities.
