Ireland’s New Tenancy Laws: What Landlords and Tenants Need to Know From March 2026
The Irish rental sector underwent one of its most significant legal reforms in decades on 1 March 2026, following the introduction of the new residential tenancy legislation and associated amendments to the Residential Tenancies framework.
The reforms are designed to strengthen tenant protections, reform rent controls, and alter the circumstances in which landlords may terminate tenancies. While the legislation aims to create greater security and stability within the private rental market, it also introduces a more complex compliance environment for landlords, investors, managing agents, and tenants alike.
Importantly, the new rules generally apply only to new tenancies created on or after 1 March 2026. Existing tenancies remain subject to the previous regime unless otherwise stated.
1. Introduction of “Tenancies of Minimum Duration” (TMDs)
One of the most significant reforms is the replacement of the traditional Part 4 tenancy structure for new tenancies with a new “Tenancy of Minimum Duration” (“TMD”).
Under the new system:
• New tenancies created from 1 March 2026 operate on rolling six-year tenancy cycles.
• Once a tenant has occupied the property continuously for six months without receiving a valid Notice of Termination, they acquire enhanced security of tenure.
• During the protected six-year period, landlords may terminate only on limited statutory grounds.
This represents a substantial shift away from the previous framework, under which landlords had broader termination rights after the expiry of fixed-term leases.
2. Distinction Between “Large” and “Small” Landlords
The legislation now differentiates between:
• “Small landlords” (generally those owning three or fewer tenancies), and
• “Large landlords” (four or more tenancies or certain corporate landlords).
This distinction is critically important because termination rights differ depending on landlord classification.
Small Landlords
Small landlords retain certain termination rights during a TMD, including where:
• the landlord or a family member intends to occupy the property;
• the landlord experiences financial hardship;
• the property is to be substantially refurbished;
• the property is to be sold; or
• the property is no longer suitable to the tenant’s needs.
Large Landlords
Large landlords face significantly more restrictive termination rights. In many cases, they may no longer terminate during the protected period merely because they intend to sell, renovate, or change use of the property.
The reforms are expected to have substantial implications for institutional investors, approved housing bodies, and PRS operators.
3. National Rent Control System Replaces RPZ Model
Another major reform is the replacement of the Rent Pressure Zone (“RPZ”) system with a national rent control framework.
For applicable tenancies:
• annual rent increases are capped at the lower of:
o 2% per annum; or
o the rate of inflation as measured by the Consumer Price Index (“CPI”).
This effectively extends rent regulation nationwide rather than limiting it to designated RPZ areas.
The legislation also imposes stricter procedural obligations on landlords when reviewing rent, including:
• mandatory RTB notifications;
• provision of supporting calculations;
• evidence of comparable market rents from the RTB Rent Register.
Failure to comply may invalidate a rent review notice.
4. Resetting Rent to Market Levels
A controversial aspect of the reforms is the new ability to “reset” rent to market value in certain circumstances.
For new tenancies created after 1 March 2026:
• landlords may reset rent to current market levels at the commencement of a new tenancy where:
o the previous tenant left voluntarily;
o the previous tenancy ended because of tenant breach; or
o the property no longer suited the tenant’s needs.
Thereafter:
• rent may generally only be reset again at the end of each six-year cycle.
This mechanism seeks to balance stronger tenant protections with maintaining investment incentives within the rental market.
Critics have argued that the reforms may lead to sharp rent increases between tenancies, particularly in high-demand urban areas.
5. Enhanced Procedural Requirements for Landlords
The reforms place additional compliance obligations on landlords and agents.
Key procedural changes include:
• mandatory service of notices on both tenants and the RTB simultaneously;
• stricter documentary requirements for Notices of Termination;
• greater evidential requirements for rent reviews;
• increased tenant rights to challenge unlawful rent setting.
The RTB also receives enhanced oversight and enforcement powers under the new regime.
Landlords who fail to comply with statutory formalities risk:
• invalid notices;
• RTB sanctions;
• compensation orders;
• administrative penalties.
6. Existing Tenancies Remain Under Previous Rules
A critical point often misunderstood by landlords and tenants is that the March 2026 reforms generally do not apply retrospectively.
Tenancies already in existence before 1 March 2026 remain governed by the previous Residential Tenancies regime and existing Part 4 protections.
However, if an existing tenancy ends and a new tenancy is created after 1 March 2026, the new tenancy may fall within the revised framework.#
7. Practical Implications
For Landlords
Landlords should urgently review:
• tenancy documentation;
• notice procedures;
• rent review practices;
• RTB registration compliance;
• portfolio structuring.
The distinction between “small” and “large” landlord status may materially affect future exit strategies and asset management decisions.
For Tenants
Tenants benefit from:
• stronger security of tenure;
• enhanced protection from no-fault terminations;
• greater transparency in rent setting;
• stronger dispute resolution rights.
However, concerns remain regarding affordability and the potential for increased rents at the commencement of new tenancies.
Conclusion
The March 2026 tenancy reforms represent a fundamental restructuring of Irish residential tenancy law. The legislation significantly strengthens tenant protections while simultaneously attempting to maintain investment within the private rental sector.
Given the complexity of the new framework, both landlords and tenants should seek legal advice where disputes arise regarding:
• tenancy termination;
• rent reviews;
• RTB compliance;
• landlord classification; or
• security of tenure rights.
As the legislation is interpreted by the RTB and the courts over the coming years, further legal developments and clarifications are expected.
