Renting in Ireland: the rules

Private lettings of self-contained homes are governed by the Residential Tenancies Act 2004 as amended, most recently by the Residential Tenancies (Miscellaneous Provisions) Act 2026 (signed 24 February 2026), with the main changes applying to tenancies created from 1 March 2026. A tenancy can be written, spoken or implied, and no contract can take away rights under the Act. The RTB publishes a template agreement and encourages written leases. A fixed-term lease does not cut these rights short: after six months in the home without a valid notice of termination, the tenant gains security of tenure (called Part 4 rights) whatever the lease says (RTB, as of 2026-09).

What that security looks like depends on the start date. Tenancies created from 1 March 2026 run in rolling six-year 'Tenancies of Minimum Duration'. With a large landlord (four or more tenancies, or any company) the tenancy is effectively unlimited, because it can only be ended for tenant breach or if the home no longer suits the tenant's needs. With a small landlord (one to three tenancies) there are a few extra grounds during and at the end of each six-year cycle (see Notice). Tenancies created between 11 June 2022 and 28 February 2026 are 'tenancies of unlimited duration' (Residential Tenancies (Amendment) Act 2021) and can be ended for six reasons, including sale and landlord's own use. Older six-year Part 4 cycles all turn into unlimited tenancies by 11 June 2028 (RTB, as of 2026-09).

The landlord must register every tenancy with the RTB within one month of the start and again every year on the anniversary. Registration costs €40 a year plus €10 for each month it is late (RTB, as of 2026-09). Since 1 March 2026 the landlord must also give the tenant, and send the RTB, a rent-setting notice at the start explaining how the rent was set. Student-specific accommodation, Approved Housing Body and cost-rental homes follow partly different rules.

For tenancies created from 9 August 2021, a landlord cannot ask for a deposit of more than one month's rent, or more than one month's rent in advance, so no more than two months' rent in total to secure a home (Residential Tenancies (No. 2) Act 2021; RTB and Citizens Information, as of 2026-09). A tenant may choose to pay more in advance, but cannot be required to. Students in student-specific accommodation can opt out of the cap only when they pay rent and fees to the same education provider.

The landlord (or their agent) holds the deposit. A state deposit protection scheme run by the RTB is provided for in law but has still not been brought into force (Citizens Information, as of 2026-09). The deposit must be returned promptly at the end of the tenancy, minus only rent arrears, unpaid bills the tenant was responsible for, damage beyond normal wear and tear, or losses from leaving without proper notice or breaking a fixed term early. A landlord cannot hold the tenant's belongings against money owed.

Take dated photos and check the inventory when you move in and out, pay by traceable transfer and get a receipt. A tenant can apply to the RTB (mediation is free, adjudication costs €30). Licensees such as lodgers are outside the RTB and may have to use the Small Claims procedure instead (Threshold).

From 1 March 2026, Rent Pressure Zones were abolished and a national system of rent control covers every private tenancy and student-specific accommodation. Rent can be reviewed once every 12 months, and the increase is capped at 2% or the rate of inflation (Consumer Price Index), whichever is lower (Residential Tenancies (Miscellaneous Provisions) Act 2026; RTB, as of 2026-09). In apartments and student accommodation where construction started on or after 10 June 2025, rent can rise with inflation without the 2% ceiling. Approved Housing Body and cost-rental tenancies have their own rent rules. Before March 2026 the whole country had already been a Rent Pressure Zone since June 2025 (Residential Tenancies (Amendment) Act 2025).

A landlord can reset the rent to market level only in set cases, and only for tenancies created from 1 March 2026: at the start of a new tenancy if the previous tenant left by choice, breached their obligations or the home no longer suited them; for a first-ever letting; after two years with no tenancy (one year for a protected structure); after a genuine substantial renovation; and at the end of each six-year cycle. After a 'no-fault' termination (sale, own use, change of use) the next tenancy cannot be reset for two years. Tenancies created before 1 March 2026 can never be reset to market rent while they last. Student-specific accommodation may reset once every three years, starting 1 March 2029 (RTB, as of 2026-09).

Every rent review needs a written notice served at least 90 days before the new rent applies, with a copy to the RTB, the landlord's calculation from the RTB Rent Calculator and three comparable rents from the RTB Rent Register; a notice not sent to the RTB is invalid. A tenant can challenge a rent increase at the RTB before it takes effect or within 28 days of receiving the notice, and a challenge to a market-rent reset can lead to repayment of overpaid rent and damages of up to €20,000 (RTB, as of 2026-09).

A tenant can leave for any reason by giving a signed written notice of termination: 28 days if the tenancy is under six months old, 35 days for six months to one year, 42 days for one to two years, 56 days for two to four years, 84 days for four to eight years and 112 days after eight years (RTB, as of 2026-09). Leaving before the end of a fixed term can cost the deposit or rent for the rest of the term, unless there is a break clause, the landlord agrees, the landlord refuses consent to sublet or assign, or the landlord has failed to fix a breach (then 28 days' notice), or there is imminent danger (7 days).

A landlord must give written notice, send a copy to the RTB, and give at least 90 days if the tenancy is under six months old, 152 days for six months to one year, 180 days for one to seven years, 196 days for seven to eight years and 224 days after eight years (RTB, as of 2026-09). Rent arrears require a 28-day warning notice, copied to the RTB, before a 28-day termination notice; other tenant breaches need a warning first; serious anti-social behaviour allows 7 days. Any landlord can end a tenancy in the first six months without a reason, but must now copy the notice to the RTB.

After six months, the grounds depend on the start date and landlord size. For tenancies from 1 March 2026, large landlords (four or more tenancies, or companies) can only end the tenancy for tenant breach or because the home no longer suits the tenant's needs. Small landlords (one to three tenancies) may also end it during a six-year cycle for their own or a close relative's use or to sell to avoid serious financial hardship, and at the end of the cycle to sell, for their own or a family member's use, to substantially renovate or to change the use. A tenant served with notice can ask the RTB to confirm the landlord's size. Tenancies created before 1 March 2026 can be ended for six reasons: breach, unsuitability, sale within nine months, landlord or family use, substantial refurbishment, or change of use. Sale, own use and renovation notices need a statutory declaration. A tenant who disputes a notice has 90 days to go to the RTB (28 days if the notice is for breach) (RTB, as of 2026-09).

The landlord must keep the home up to the legal minimum standards (Housing (Standards for Rented Houses) Regulations 2019): no damp and structurally sound, hot and cold water, heating the tenant can control, ventilation, natural and artificial light, fire detection and a fire blanket, carbon-monoxide alarms where needed, window restrictors, safe gas and electrics, bin storage, and for leases under ten years a four-ring hob, oven, grill, microwave, fridge-freezer and sink (RTB, as of 2026-09). Local councils enforce the standards and can inspect, issue improvement notices and bar re-letting. The landlord must also do repairs within a reasonable time (or refund reasonable costs of essential repairs a tenant arranged), insure the structure and give the tenant a rent book or rent receipts. The tenant must keep the home in good order, report problems promptly and allow access by arrangement; entry is by permission except in emergencies.

Who pays electricity, gas, broadband and bin collection is not fixed by law but by the tenancy agreement; the tenant pays whatever charges the agreement specifies, such as utility bills, waste collection or a share of apartment management fees, so check this before signing (Citizens Information, as of 2026-09). Local Property Tax is paid by the owner, not by a tenant on a lease of under 20 years (Revenue, as of 2026-09). Tenants should arrange their own contents insurance.

Letting agents act for and are paid by the landlord, and must hold a licence from the Property Services Regulatory Authority, whose public register you can check. Whatever an agent says, the upfront cap of one month's deposit plus one month's rent applies.

Ireland has no address registration like the Spanish padrón or German Anmeldung. The number that matters is the PPS number (Personal Public Service number), which you need for work, tax and public services. To get one from the Department of Social Protection you show photo ID, a reason (such as a job) and proof of address dated within three months: a household utility bill, an official letter, a lease or tenancy agreement, or a letter from a hotel, hostel or accommodation owner (Citizens Information, as of 2026-09). A written lease or letter from your landlord therefore helps you get set up.

Landlords often ask for a PPS number, ID, an employer letter, payslips and references, and the RTB register links tenancies to named parties; since the 2026 Act the RTB and Revenue can exchange landlord and tenant details, including PPS numbers, to find unregistered tenancies (Residential Tenancies Act 2004 s.147A as substituted, 2026). Before paying anything, check that the address has a registered tenancy using the RTB's online register search.

The Housing Assistance Payment (HAP) is the main rent support: the council pays the landlord and the tenant pays a weekly income-based contribution to the council. It is only open to people on a council housing list, which needs a long-term right to live in Ireland, income under the limit and a housing need; people with temporary protection cannot apply. Rents must be within local HAP limits, which councils can exceed by up to 35%. It is illegal to discriminate against tenants because they receive HAP, including stating 'no HAP' in an advert (Citizens Information, as of 2026-09).

A tenant needs the landlord's written permission to sublet (let the home to someone else while staying responsible) or assign (hand the whole tenancy over to someone new). If the landlord refuses, the tenant can end the tenancy by notice, even during a fixed term. Subletting and assignment are not allowed in Approved Housing Body, student-specific or cost-rental tenancies. A flatmate who shares the home with the tenant is not a sub-tenant (RTB, as of 2026-09).

A legal sub-tenancy must be registered by the head tenant with the RTB on the paper RTB1 form, and both sides can then use RTB disputes. A sublet the landlord does not know about may be an illegal sub-tenancy, and the RTB may not be able to hear it. If the head tenant is given notice, they must pass it on to the sub-tenant within the set time. An assignee to someone other than an existing sub-tenant has to live there six months before gaining security of tenure.

Renting a room in the owner's own home (digs, lodging), employer housing and many sublets from other tenants are licences, not tenancies. Licences are not registered with the RTB, have no statutory notice periods, and most licensees cannot bring disputes to the RTB (Threshold, as of 2026-09). Get a written licence agreement with the rent, deposit, bills and notice; Threshold publishes a free template.

To let legally: register each tenancy with the RTB within one month and every year after (€40 a year, €10 a month late); failing to register can lead to prosecution with fines of up to €5,000, or an RTB sanction of up to €15,000 per tenancy (RTB, as of 2026-09). Have a valid Building Energy Rating (BER) certificate and show the BER in every advert (Citizens Information); the BER scale changed to the EU-style scale on 24 May 2026. Meet the minimum standards, take no more than one month's deposit and one month's rent in advance, give a rent-setting notice to the tenant and the RTB at the start, and follow the 2% or CPI cap with RTB-copied rent review notices. Since 1 March 2026, a small landlord relying on a small-landlord ground must also lodge a statement confirming they have one to three tenancies.

Rental profit is added to your other income and taxed at 20% up to €44,000 for a single person and 40% above (2026 bands), plus USC (0.5% to 8%) and PRSI (4.2% until 30 September 2026, 4.35% from 1 October 2026) (Revenue, Citizens Information, as of 2026-09). Deductible costs include repairs, insurance, management and letting fees, the RTB fee, service charges and costs you pay for the tenant, 12.5% a year wear-and-tear allowance on furniture and appliances, and 100% of mortgage interest on a loan to buy, improve or repair the property, but only while the tenancy is registered with the RTB. Individual landlords can also claim Residential Premises Rental Income Relief of up to €1,000 a year in 2026 and 2027 (lower of that or 20% of rental profit), against income tax only, if they keep the property let until the end of 2027. PAYE workers with net rental income under €5,000 declare it on Form 12; above that you must register for self-assessment and file Form 11. Non-resident landlords either use an Irish collection agent or the tenant must withhold 20% of the rent for Revenue (Revenue, as of 2026-09). Budget 2027 is due on 6 October 2026 and may change these figures.

Letting a room in your own home can be tax-free under Rent-a-Room Relief if gross income from it stays at or under €14,000 a year; lettings to your own child, your employer and short-term guests (28 days or less, except students and four-day digs) do not qualify, and above the limit the whole amount is taxable (Revenue, as of 2026-09). Short-term letting of a second property or a whole home for more than 90 days a year already needs planning permission in most cases. A national short-term letting register run by Fáilte Ireland opens on 1 December 2026 for stays of 21 nights or less, with registration required by 31 December 2026, and new planning rules are planned under the Short Term Letting and Tourism Bill 2025 (gov.ie, 13 May 2026; Citizens Information, as of 2026-09). The Residential Zoned Land Tax (3% of land value, first payable in 2025) targets undeveloped zoned land and does not apply to existing residential properties that pay Local Property Tax.

Tenancy disputes go to the RTB rather than the courts, as long as the tenancy is registered or is one that should be. Mediation is free and run by phone; adjudication costs €30 and ends in a binding decision; either side can appeal to a Tenancy Tribunal within 10 working days, for €30 after mediation or €85 after adjudication, as a full rehearing (RTB, as of 2026-09). Time limits: challenge a notice of termination within 90 days (28 days if it is for breach), and a rent increase before it takes effect or within 28 days of the notice. Tenants can also report a landlord to the RTB for investigation of breaches such as unlawful rent increases, which can lead to sanctions.

The outcome is a Determination Order. If the other side does not comply, it can be enforced in the District Court; the RTB supplies case documents and template court papers and, in some cases, takes the enforcement case with its own lawyers and covers some or all costs. Enforced orders are published (RTB, as of 2026-09). Minimum-standards problems can also be reported to the local council for inspection.

Free help: Threshold, the national housing charity, gives free confidential advice to tenants and licensees (freephone 1800 454 454); Citizens Information explains the rules and can help with forms; FLAC (Free Legal Advice Centres) runs a legal information line on 01 906 10 10 and free legal advice appointments. Licensees who cannot use the RTB may use the Small Claims procedure for a deposit.
