Tenant Rights in Ireland 2026: Security of Tenure, Rent Caps, Deposits and the RTB

Renting in Ireland changed more in the year to March 2026 than in the previous decade. A national rent cap replaced Rent Pressure Zones, tenancies that begin on or after 1 March 2026 carry a new 6-year security-of-tenure model, and the grounds on which a landlord can end a tenancy now depend on how many tenancies that landlord holds.

This overview maps the core tenant rights in the Republic of Ireland in 2026: security of tenure, rent rules, minimum standards, deposits, RTB registration, and how to enforce your rights when something goes wrong.

Who is protected by Irish tenancy law?

The Residential Tenancies Acts, policed by the Residential Tenancies Board (RTB), cover private rented tenancies, including tenancies supported by HAP or RAS, student-specific accommodation, and approved housing body and cost-rental homes. The rent-setting rules do not apply to approved housing body or cost-rental tenancies, and they operate differently for student accommodation.

Two groups fall outside this framework entirely: local-authority tenants, and licensees who rent a room in their landlord's own home. If you share your landlord's home, you have no Residential Tenancies Act protection, whatever your agreement says.

Security of tenure: which regime covers your tenancy?

Everything in Irish tenancy law now pivots on one date. A tenancy created before 1 March 2026 stays under the old regime; a tenancy created on or after that date falls under the new one.

The 6-year TMD cycle binds the landlord, not the tenant. A tenant can end the tenancy at any time by serving the correct notice period, whatever stage the cycle has reached.

Smaller and larger landlords: the 2026 dividing line

For tenancies created on or after 1 March 2026, what a landlord may do depends on their size. A smaller landlord holds 3 or fewer tenancies and is not a company. A larger landlord holds 4 or more tenancies, or is a company of any size.

Larger landlords can end one of these tenancies only for tenant breach or because the dwelling no longer suits the household's needs. They can no longer terminate to sell: they must sell with the tenant in place. Smaller landlords keep limited additional grounds, such as a hardship sale or a family member needing the home, backed by statutory declarations, with wider options at the end of each 6-year cycle. The full breakdown, including the grounds that still apply to pre-2026 tenancies, is in our eviction rules guide.

Rent rules in 2026: the national cap

Since 1 March 2026, one rent-control system covers the whole country. Rent can rise at most once every 12 months, by 2% a year or CPI inflation, whichever is lower. A rent review notice must go to the tenant and the RTB on the same day, at least 90 days before the new rent takes effect.

There is one important exception to the 12-month cycle. If your area only became a Rent Pressure Zone in the two years before 1 March 2026, your first review cannot take place until 24 months after the rent was last set for the tenancy. Reviews after that follow the normal 12-month cycle. This matters most for the roughly 40,000 tenancies swept into rent control by the nationwide designation in June 2025.

A tenant can dispute an increase up to the later of two dates: the day the new rent is due to start, or 28 days after receiving the notice. Because the notice must give at least 90 days, that normally means you have until the new rent's start date, not 28 days. If the notice itself is invalid there is no time limit.

Newly built apartments with a commencement notice on or after 10 June 2025 are capped by CPI only, with no 2% ceiling. Market-rent resets are confined to narrow windows, and where a tenancy was ended so the landlord could sell, house themselves or a family member, or change the use, no reset to market is possible for two years afterwards. For the full mechanics, including what happened to Rent Pressure Zones, see our guide to Ireland's national rent cap and the end of RPZs.

Minimum standards your home must meet

Every private rented dwelling must meet the Housing (Standards for Rented Houses) Regulations 2019 (S.I. No. 137 of 2019). Among other things, the dwelling must be structurally sound and free of damp, with proper sanitary facilities, heating the tenant can control, cooking and food-storage facilities, laundry facilities, ventilation, lighting, fire safety including smoke alarms, carbon-monoxide alarms, and refuse facilities.

Local authorities, not the RTB, inspect rented homes and enforce these standards. A tenant can also refer a dispute to the RTB where a landlord fails to carry out repairs required by their obligations.

Deposits: the upfront-payment ceiling

A landlord cannot ask for a deposit of more than 1 month's rent, and total upfront payments cannot exceed 2 months' rent: one month's deposit plus one month's rent in advance. The deposit cap has no exceptions.

There is one narrow exception on the advance-rent side. A student may agree to pay more than one month's rent in advance only where they pay both their tuition fees and their rent to the same education provider, which in practice means college-owned accommodation. Since 19 July 2024 that is the only case in which a larger advance payment is lawful, so a privately-run student residence cannot ask you for a term or a year upfront.

Ireland still has no deposit protection scheme. Legislation for an RTB-run scheme was passed in 2015 but has never been brought into effect, so the landlord or agent simply holds your money. The deposit must be returned promptly and in full when you leave properly, with deductions allowed only for rent arrears, unpaid bills you were liable for, damage beyond normal wear and tear, or losses caused by leaving without proper notice. Deposit retention is one of the most common RTB dispute types. Our guide to deposits and landlord obligations covers the details.

RTB registration and the public rent register

Your landlord must register the tenancy with the RTB within 1 month of it starting, and renew the registration annually. The standard fee is €40 a year per tenancy, with a €10 monthly late fee and a composite €170 fee for up to 10 tenancies in one building registered together on time.

Since 1 March 2026, registration also captures bed spaces, floor area and BER rating. That data feeds the new public rent register, which publishes rents and property details and anchors the 3-comparable-property requirement for any market-rent reset.

Ending a tenancy: notice periods

Termination notice periods were not changed by the 2026 reforms. A landlord must give between 90 days (tenancy under 6 months) and 224 days (8 years or more), depending on how long you have rented. A tenant must give between 28 and 112 days on the same sliding basis, and can leave at any point in the 6-year cycle with proper notice.

In purpose-built student-specific accommodation the duration tables do not apply at all: the minimum is a flat 28 days on both sides.

Since 1 March 2026, notices can also be served electronically through a system that records sending, and since 28 February 2026 a landlord must copy every notice of termination to the RTB on the same day it is served on the tenant, or the notice is invalid. A landlord can never simply remove you: enforcing a termination runs through the RTB, and self-help eviction is unlawful. If you want to challenge a notice, a validity dispute must reach the RTB within 90 days of receiving it, or 28 days where the notice is for tenant or landlord default. The band tables and special cases are in our notice of termination guide, or you can get an instant answer from the Ireland notice period calculator.

You may have a right to be offered the home back. If a tenancy was ended so the landlord could sell but no sale agreement is signed within 9 months of the notice period ending, or the landlord or family moved in and the home is re-advertised within 12 months, or the use was changed and it is let again within 12 months, or it is let again after a refurbishment, the landlord must offer you the tenancy again. Our eviction rules guide sets out how to enforce that at the RTB.

Taking a dispute to the RTB

The RTB, not the courts, is the first venue for almost every landlord-tenant dispute: deposits, rent increases, standards and repairs, notice validity, and unlawful eviction.

For a rent increase, refer the dispute by the later of the new rent's start date and 28 days after you received the notice. For the validity of a notice of termination, the deadline is 90 days from receiving the notice, or 28 days where it was served for tenant or landlord default. Threshold's Tenancy Protection Service (1800 454 454) offers free advice if you are worried about losing your home. For the wider Irish legal picture beyond renting, see our Ireland law hub.
