Tenancy Agreement Ireland: What Must Be In It (2026)

A tenancy agreement is the single cheapest piece of protection a landlord or tenant will ever buy. Get it right and most disputes never start. Get it wrong — or rely on a handshake — and you are arguing about deposits, notice and repairs with no paper trail. Irish rental law changed substantially on 1 March 2026, so a template downloaded a couple of years ago is now out of date. This guide sets out what a tenancy agreement in Ireland should contain, what the law requires separately from the agreement itself, and where a lease agreement most often goes wrong.

Does a tenancy agreement have to be in writing?

Strictly, no. Under the Residential Tenancies Act 2004 (as amended) a tenancy can be created verbally, and the tenant still gets the full statutory protections either way. The Residential Tenancies Board (RTB) encourages written agreements so both sides are clear on what was agreed.

The practical point is evidential. If a dispute reaches RTB adjudication or a tribunal, the party with a signed agreement, a dated inventory and photographs is in a far stronger position than the party relying on memory. A written agreement does not create rights the law does not already give — it proves what was agreed.

What a tenancy agreement should contain

The basics

• Full legal names of every landlord and every tenant, and the address of the property
• The start date of the tenancy and its intended term
• The rent, the payment date, and the payment method
• The security deposit and the conditions for its return
• What is included in the rent — and which utilities, bins, broadband or management charges are not
• Who is responsible for which repairs, and how the tenant reports them
• Rules on subletting, assignment and adding occupants
• Rules on pets, smoking and alterations

The clauses landlords most often leave out

Contact details are a legal obligation, not a courtesy: a landlord must give the tenant details allowing the landlord or their agent to be contacted at all reasonable times. Where an agent manages the property, say so and name them.

Access and inspection should be spelled out. A tenant is entitled to peaceful and exclusive occupation; a landlord has no general right to let themselves in. Where a landlord is selling and wants viewings, the date and time must be agreed with the tenant in advance.

An inventory and condition report, signed by both sides and backed by dated photographs, is the clause that saves the most money. Deposit disputes are among the most common cases the RTB deals with, and they usually turn on whether damage existed at the start.

Money: deposits, advance rent and rent increases

For all tenancies created since 9 August 2021, a landlord cannot require upfront payments of more than the equivalent of two months’ rent — that is, a deposit of no more than one month’s rent plus no more than one month’s rent in advance. An agreement demanding more than that is asking for something the law does not allow.

On rent, the picture changed on 1 March 2026. Rent Pressure Zones were replaced by a national system of rent control covering private tenancies and student-specific accommodation everywhere in the State. Rent can be reviewed once a year and increased by no more than 2%, or by the rate of inflation measured by the Consumer Price Index if that is lower. Newly built apartments and new student accommodation where construction commenced on or after 10 June 2025 follow CPI without the 2% cap.

Where a landlord sets or re-sets a rent, they must now give the tenant a rent setting notice explaining how the figure was reached, including three comparable properties drawn from the RTB Rent Register, and send the same information to the RTB. A rent review clause in a lease agreement that simply says “rent may be increased annually at the landlord’s discretion” is unenforceable to the extent it conflicts with these rules.

Security of tenure: what your agreement cannot shorten

For tenancies created on or after 1 March 2026, a tenant who has been in occupation for six continuous months without receiving a valid notice of termination acquires a tenancy of minimum duration lasting six years, renewing in six-year cycles.

The grounds for ending it now depend on the size of the landlord. A larger landlord — four or more tenancies, or any registered company — can end a tenancy of minimum duration only where the tenant breaches their obligations or the property no longer suits the tenant’s needs. A smaller landlord with three or fewer tenancies has additional grounds, including needing the property for themselves or an immediate family member, or selling to avoid undue hardship, with further grounds available at the end of each six-year cycle. Statutory declarations are required for several of these grounds.

None of this can be contracted out of. A fixed-term clause saying the tenancy “ends after 12 months” does not remove statutory security of tenure. Tenancies created before 1 March 2026 continue under the older rules, which is why the start date matters so much.

Obligations that sit outside the agreement

• RTB registration. The landlord must register the tenancy with the RTB within one month of the commencement date and again on each anniversary. The standard fee is €40 a year, with a €10 late fee for each month a registration is late. Landlords must now also supply floor area, bed spaces and BER to feed the Rent Register.
• Minimum standards. The Housing (Standards for Rented Houses) Regulations 2019 set physical standards covering structural repair, ventilation, lighting, heating and the safety of gas, oil and electrical installations. Local authorities enforce them.
• Rent book. Tenants are entitled to a rent book or an equivalent document recording rent paid and tenancy details, enforced by the local authority.
• Notices. Since 1 March 2026, notices — including notices of termination — may be served electronically, provided they go to a contact point the other party uses and the system records that the notice was sent.

Where DIY templates go wrong

The recurring problems we see are clauses purporting to allow the landlord to retain a deposit for reasons the RTB would not accept; “no pets, no children” style terms that raise equality issues; rent review clauses that predate the 2026 rules; termination clauses that ignore statutory notice periods; and agreements that quietly try to convert a tenancy into a licence to avoid the Act altogether. Whether an arrangement is a tenancy or a licence is determined by the substance of the occupation, not by the label on the document.

The RTB publishes a free sample residential tenancy agreement, updated for tenancies created from 1 March 2026, and a sample inventory and condition report. Those are a sound starting point. A property with unusual features — a part-let building, a shared entrance, an existing tenant, commercial use, or a management company overlay — usually needs the document adapted rather than filled in.

Frequently asked questions

Does a tenancy agreement have to be in writing in Ireland?

No. A tenancy can be created verbally and the tenant still has full statutory rights. The RTB nonetheless recommends a written agreement, because in a dispute the written record is what an adjudicator can rely on.

What is the difference between a lease agreement and a tenancy agreement?

In everyday Irish use the terms are interchangeable for residential letting. Where a distinction is drawn, a lease agreement usually means a fixed term of a year or more, while a tenancy agreement covers periodic arrangements. The Residential Tenancies Act applies either way, so the label does not change the underlying rights.

Can I use a free tenancy agreement template?

You can, and the RTB’s own template is a reasonable base for a straightforward private letting created from 1 March 2026. Templates found elsewhere online are often drafted for another jurisdiction or predate the 2026 reforms, and any clause conflicting with the Act is unenforceable.

How much deposit can a landlord ask for under a tenancy agreement?

Upfront payments are capped at the equivalent of two months’ rent for tenancies created since 9 August 2021 — a deposit of at most one month’s rent, plus at most one month’s rent in advance.

Does a fixed-term lease agreement end automatically after 12 months?

Not necessarily. A tenant who has been in occupation for six months without a valid notice of termination acquires statutory security of tenure, and for tenancies created on or after 1 March 2026 that means a six-year tenancy of minimum duration. The contractual term does not override the statutory protection.
