Under Section 34(b) of the Residential Tenancies Act 2004, a landlord may terminate a Part 4 tenancy where the tenant has failed to comply with an obligation of the tenancy. Anti social behaviour is the most common reason landlords rely on this ground — alongside causing nuisance to neighbours, unauthorised subletting, and damage to the property beyond fair wear and tear.

This page explains how much notice you must give for anti-social behaviour, the crucial difference between serious and less-serious anti-social behaviour, the evidence and wording a valid notice needs, and how to avoid having the notice struck out at an RTB hearing.

Key Points for Landlords

Notice Period for Anti-Social Behaviour

The notice period depends on the severity of the behaviour. For most breaches of obligation (including persistent but less-serious anti-social behaviour), the standard notice scale under Section 66 of the Residential Tenancies Act 2004 applies, based on how long the tenancy has lasted:

Tenancy DurationNotice Period
Less than 6 months28 days
6 months to 1 year35 days
1 to 2 years42 days
2 to 3 years56 days
3 to 4 years84 days
4 to 5 years112 days
5 to 6 years140 days
6 to 7 years168 days
7 to 8 years196 days
8 or more years224 days
Shorter notice for serious cases: Where the anti-social behaviour is serious — for example behaviour that is a threat to the safety of others, or that causes serious damage — the Act permits a reduced notice period (as short as around 7 days), rather than the standard scale above. Because this is fact-specific, confirm the exact period that applies to your case with the RTB before serving. See our full guide to RTB notice periods.

Serious vs Less-Serious Anti-Social Behaviour

The Residential Tenancies Act draws an important distinction that affects both the notice period and what you must prove:

Serious anti-social behaviour

This is behaviour that consists of conduct constituting a serious danger to the life or wellbeing of other occupants or neighbours, or behaviour that causes (or could cause) fear, injury or serious damage — for example violence, threats, intimidation, or drug-dealing. For serious behaviour, the landlord does not have to give the tenant the same opportunity to put things right, and a reduced notice period may apply.

Less-serious anti-social behaviour

This covers persistent but lower-level conduct such as repeated noise, untidy or disruptive use of common areas, or nuisance that interferes with neighbours' peaceful enjoyment. For this category you should normally warn the tenant in writing and give a reasonable opportunity to stop before serving notice, and the standard notice period applies.

Important: Section 34(b) notices are frequently challenged at RTB hearings. Without documented evidence of the breach — and, for less-serious behaviour, a prior warning — the notice may be ruled invalid. Build your paper trail before serving. See the common reasons notices are ruled invalid.

What the Notice Must Contain

A notice on this ground must meet the general validity requirements of Section 62 of the RTA 2004 and, importantly, state the reason clearly. For a breach-of-obligation termination the notice must:

Frequently Asked Questions

How much notice for anti social behaviour from a tenant?

For less-serious anti-social behaviour the standard scale applies (28 days up to 224 days, depending on tenancy length). For serious anti-social behaviour that endangers others, the Act allows a reduced notice period — as little as around 7 days. Because the figure depends on the facts, confirm the period that applies to your case with the RTB.

Can you evict a tenant for anti social behaviour in Ireland?

Yes. Anti-social behaviour is a breach of tenant obligations under Section 34(b) RTA 2004, so a landlord can terminate the tenancy by serving a valid Notice of Termination. You cannot remove the tenant yourself — if they overhold past the termination date you must apply to the RTB for a determination order. Self-help eviction is illegal under Section 78.

What counts as anti-social behaviour under the RTA 2004?

Section 17 of the Residential Tenancies Act 2004 sets out tenant obligations. Anti-social behaviour includes persistent noise, intimidation of neighbours, drug-related or violent conduct, damage to common areas, and behaviour that substantially interferes with the peaceful enjoyment of other occupants. A single minor complaint is usually not enough for less-serious cases — a pattern is typically required.

Do I need a prior warning before serving notice for breach of obligations?

For less-serious behaviour, yes in practice — a written warning giving the tenant a chance to stop strongly strengthens your case, and the RTB adjudicator will consider whether the tenant had an opportunity to rectify. For serious anti-social behaviour, the same opportunity to remedy does not apply, but documented evidence is still essential.

Can I serve notice for damage to the property?

Yes, where the damage goes beyond fair wear and tear and breaches the tenant's obligation to maintain the property under Section 16(f) RTA 2004. Document the damage with photographs and obtain repair quotes to support your case.
