Anti-social behaviour and the 7-day notice

A landlord may end a tenancy on 7 days' notice for one reason only: serious anti-social behaviour. It is the shortest notice period in the Act, it needs no warning, and the landlord must prove the behaviour to a high standard. If the reason on your notice is anything less than that, the 7 days may not be open to the landlord at all.

The notice period is short but the dispute window is not. You have 28 days from the date of service to refer the notice to the RTB, which runs past the termination date itself. The notice checker tests the notice against section 62 and works out both dates.

This guide covers the Republic of Ireland. Threshold on 1800 454 454, Monday to Friday 9am to 9pm, reads these notices every week, and the call is free.

What the Act means by anti-social behaviour

Section 17 of the Act defines anti-social behaviour in three parts. The first is behaviour that is a criminal offence and that is reasonably likely to affect the well-being or welfare of others directly. The second is behaviour that causes, or could cause, fear, danger, injury, damage or loss to any person in the dwelling or nearby, including violence, intimidation, coercion, harassment or obstruction. The third is persistent nuisance or annoyance to people living nearby.

Only the first two parts are serious anti-social behaviour, and only they open the 7-day period. The third part, persistent nuisance, is a breach of your obligations like any other. For that the landlord must give a written warning, let a reasonable time pass, and then serve 28 days' notice.

The difference matters. Loud music, bins left out, an argument with a neighbour, a dog that barks: none of those is serious anti-social behaviour on its own. An assault, a threat to a neighbour, dealing drugs from the flat, or deliberately damaging the building would be.

Why no warning is needed

For most breaches the Act requires a warning first, so the tenant has a chance to put it right. For serious anti-social behaviour it does not, because the behaviour is of a kind that cannot be put right and that puts other people at risk. The landlord may serve the notice as soon as the behaviour is known.

That is also why the period is 7 days. The Act balances a very short period with a very narrow ground and a heavy burden of proof. A landlord who uses the ground loosely, to end a tenancy they could not otherwise end, is taking a risk at the RTB.

The period is the same for a smaller landlord and a larger one, and for a tenancy that began before or after 1 March 2026. Serious anti-social behaviour is one of the four grounds open to a larger landlord against a tenancy that began on or after 1 March 2026.

What the notice must still contain

A 7-day notice is a notice of termination and must pass every test in section 62. It must be in writing and signed by the landlord or their agent, dated, state the date of service and the termination date, and give the reason. It must say that you may refer a dispute to the RTB within 28 days. A copy must reach the RTB within 7 days of service.

The reason must be specific enough to answer. "Anti-social behaviour" alone tells you nothing. The notice, or a letter with it, should say what is alleged, when, and where. A notice that gives no particulars may be invalid, and you can say so in your referral.

The termination date must give you the whole of the seventh day after service. Notice of termination: what a valid notice must contain covers each requirement, and the 7-day RTB copy rule explains how to ask whether the RTB received its copy.

The standard of proof

At the RTB the landlord has to prove that the behaviour happened and that it falls within the serious parts of section 17. The burden is on the landlord, not on you. Because the notice period is so short, the RTB has treated the ground as one that needs clear and specific evidence: dates, incidents, witnesses, Garda involvement where there was any, photographs of damage.

A single complaint from a neighbour, relayed second-hand, is thin. So is a general account that the tenant is "difficult". If the behaviour was your visitor's rather than your own, the Act does cover behaviour you allowed in the dwelling, but the landlord still has to show what happened and that you permitted it.

None of this means the ground is never made out. Where there was a serious incident and the evidence is there, the RTB can uphold the notice. The point is that the landlord carries the proof, and a notice served on rumour will struggle.

How to dispute the notice

Refer the notice to the RTB within 28 days of the date of service. That is the window for a breach notice, and it does not close on the termination date. Mediation is free and private. Adjudication costs €30 and, since 14 September 2026, the hearing is public and the published report names both parties and the address. How to make an RTB dispute application covers the form and what happens next.

Do not move out and keep paying the rent. An invalid notice does not end the tenancy, and a notice on a ground the landlord cannot prove is a matter for the RTB to decide. Leaving in the seven days hands over the home before anyone has looked at the evidence.

Write your own account of the incident, or of the fact that there was none, while it is fresh. Note who was there, what was said, and whether the Gardaí were called. Keep every message from the landlord, the agent and the neighbours. If there was an incident involving someone else in the home, say so plainly. RTB evidence: what to bring sets out how to present it.

The landlord's only lawful route, if you stay, is the RTB and then the courts. Changing the locks or cutting the power in the seven days is improper conduct whatever the ground; illegal eviction, lock-outs and cut-offs says what to do if it happens.

If the behaviour was someone else's

Anti-social behaviour by another tenant in the building is the landlord's problem to deal with, not yours to suffer. Section 15 obliges a landlord to enforce the obligations of their tenants where a third party is affected. If you are the one being threatened or harassed by a neighbour who shares a landlord, tell the landlord in writing and keep the reply. You can refer a dispute against the landlord for failing to act.

Where the behaviour is a crime, ring the Gardaí on 999 or 112 if there is danger now, and otherwise report it at the local station and keep the reference number. A Garda record is also the strongest evidence either side can bring to the RTB.

Where this leaves you

The 7-day period belongs to one ground, serious anti-social behaviour, and the landlord has to prove it. Anything less needs a warning and 28 days, and most reasons need 90 days or more. The notice must still pass section 62, give particulars, and reach the RTB as a copy within 7 days. You have 28 days from service to refer it, and that window outlives the termination date. Check the notice, stay put, keep paying, and ring Threshold on 1800 454 454 before you answer the landlord. The notice journey takes the steps in order.
