Introduction
On 1 March 2026, the Residential Tenancies (Miscellaneous Provisions) Act 2026 (the Act) came into force, introducing one of the most significant structural reforms of Ireland’s private rental market in recent years.
The legislation replaces the Rent Pressure Zone (RPZ) model with a national rent regulation framework, introduces six-year Tenancies of Minimum Duration (TMDs) for all new private residential tenancies, and creates a formal distinction between small and large landlords for the purposes of termination rights.
The stated objective is to enhance tenant security while maintaining conditions that support continued private investment. The practical implications for landlords, investors and developers are material and require careful consideration.
Key Changes under the Act
(i) Three Parallel Tenancy Regimes
As the Act does not retrospectively alter the legal status of existing tenancies, the rental market will now operate across a number of overlapping tenancy regimes determined by the date on which the tenancy commenced. From 1 March 2026, Ireland’s private rental market therefore operates across three parallel tenancy regimes:
- Tenancies commenced on or before 10 June 2022 continue under the pre-existing Part 4 framework, including RPZ rent controls where applicable;
- Tenancies commenced between 11 June 2022 and 28 February 2026 become tenancies of unlimited duration once six months’ occupation has accrued (in the absence of a valid notice of termination) and remain subject to the RPZ rent regulation framework where applicable; and
- Tenancies created on or after 1 March 2026 are subject to the TMD structure introduced by the Act, including the national rent regulation framework.
(ii) Tenancies of Minimum Duration
All new private residential tenancies are TMDs with a minimum term of six years. Once a tenant has been in occupation for six months and no valid notice of termination has been served, statutory security of tenure applies. The tenancy does not automatically expire at the end of the six-year period and will continue thereafter unless lawfully terminated.
During the six-year minimum term, termination rights are significantly restricted. A central feature of the Act is the distinction between a landlord which is not a company and has three or fewer tenancies and a landlord who has four or more tenancies or is a company, with classification determined by reference to the number of tenancies rather than properties. These two categories of landlord have commonly been referred to in commentary as “small” and "large" landlords.
- Large landlords may terminate during the six-year term only in cases of tenant breach or where the dwelling is no longer suitable to the tenant’s needs. They may not terminate on grounds of sale, substantial refurbishment, change of use or occupation by the landlord or family.
- Small landlords retain limited additional flexibility. During the six-year term, they may terminate for tenant breach, unsuitability, defined financial hardship requiring sale, or occupation by a narrowly defined immediate family member. Following expiry of the six-year term, small landlords regain broader termination grounds, including intention to sell and substantial refurbishment. Large landlords do not regain equivalent no-fault termination rights.
(iii) National Rent Regulation
The Act replaces the RPZ system with a national rent regulation framework. The cap is now linked to the Consumer Price Index (CPI), replacing the previous Harmonised Index of Consumer Prices (HICP), an EU-wide measure of inflation previously used under the RPZ system.
For most properties, annual rent increases are capped at the lower of:
- CPI; or
- 2% per annum (calculated on a pro-rata basis).
This means that where CPI is below 2%, the permitted increase will be limited to CPI. Where CPI exceeds 2%, the increase is capped at 2%.
At the commencement of a tenancy, rent may be set at market rent, supported by evidence from the RTB Rent Register. During the six-year term, increases are limited to the statutory cap. Rent may be reset to market rent where a tenant leaves voluntarily and at the end of each six-year cycle (provided no unlawful termination has occurred).
(iv) New Development Exception - Newly Built Apartments and Student Specific Accommodation
An important carve-out applies to newly built apartments and student-specific accommodation with commencement notices lodged on or after 10 June 2025. For such units, rent increases are capped by CPI only and are not subject to the 2% ceiling, allowing rent increases to track inflation more closely over time. This exemption is widely regarded as a targeted attempt to preserve the viability of build-to-rent (BTR) and purpose-built student accommodation (PBSA) development.
(v) Enhanced Enforcement
The reforms are accompanied by a significant strengthening of enforcement. The Residential Tenancies Board (RTB) will receive a budget increase of over 70% in 2026, rising to €22.8 million. Landlords must disclose the previous rent and explain how any new rent has been calculated in accordance with the statutory rent regulation framework. The RTB will continue to exercise investigative and enforcement powers, including issuing binding Determination Orders and imposing sanctions for non-compliance.
Market Reaction and Supply Considerations
Initial commentary suggests a mixed market response. Certain reporting indicates renewed institutional interest in forward-fund and pre-purchase structures, with the CPI-only carve-out for new apartments and PBSA viewed as a targeted measure aimed at supporting new supply. For developers and institutional investors operating at scale, this exemption provides greater visibility in income modelling and may assist in underwriting new BTR and PBSA schemes.
At the same time, the broader reform materially alters the operating environment for private rental. A six-year minimum duration capped rental growth and restricted termination rights (particularly for large landlords) affect portfolio management flexibility and exit assumptions. For institutional-scale investors, the removal of broad no-fault termination rights requires recalibration of risk and return expectations. For smaller landlords, the extended commitment and compliance obligations may influence decisions regarding continued participation in the market.
Polling referenced in national coverage indicates that a significant proportion of respondents anticipate further rent increases and potential contraction of supply. Industry commentary has also noted the possibility of short-term rent adjustments where lawful market resets are available between tenancies prior to the commencement of new six-year cycles.
While the full impact of the reforms will only become apparent over time, it is clear that the regulatory framework now places a premium on certainty. Development viability depends on stable assumptions regarding income, exit and compliance risk. The CPI-only exemption for new development forms part of that architecture. However, given the lead-in time associated with planning, funding, procurement and construction, any increase in rental supply arising from new development is likely to emerge over the medium term rather than immediately. Even where investment appetite strengthens, delivery of new units typically follows a multi-year cycle.
The success of the reforms will therefore depend not only on strengthening tenant protections but also on whether the wider housing and regulatory framework provides sufficient certainty to support sustained investment in new supply.
Key Takeaways for Landlords and Investors
Most private landlords and institutional investors operating in Ireland will need to reassess their approach under the new regime.
Key considerations include:
- Reviewing portfolio structures to determine small versus large landlord classification.
- Reassessing termination strategies and exit assumptions.
- Updating rent review processes to ensure strict compliance with CPI/2% caps and disclosure requirements.
- Factoring six-year minimum duration commitments into underwriting and funding models.
- Evaluating the relative attractiveness of new-build BTR and PBSA opportunities under the CPI-only framework.
For professional operators, enhanced RTB enforcement underscores the importance of robust compliance systems and accurate documentation.
Conclusion
The Act introduces structural reform rather than incremental adjustment. It embeds six-year minimum tenancies, nationwide rent regulation framework and differentiated landlord treatment into the framework governing new private residential lettings. The legislation is clearly designed to enhance tenant security and increase transparency. It also recalibrates the balance of risk and flexibility within the sector.
Regulatory change of this scale will inevitably influence market behaviour. Capital allocation decisions turn on certainty, return and operational flexibility. Housing delivery, in turn, depends on development viability and confidence in a stable and coherent policy environment.
The long-term effectiveness of the reforms will depend not only on the operation of the new rent regulation framework, but on whether the wider housing ecosystem supports sustained investment in new supply. Security of tenure is a central objective of the reforms. However, in a market where availability remains constrained, the delivery of additional units at scale will be critical to achieving lasting stability. The interaction between enhanced tenant protection and sustained supply will ultimately determine how the market evolves under the new regime and whether the reforms succeed in creating the policy certainty required to support long-term investment in Ireland’s rental housing market.
