Smoke alarms in Ireland (2026)

Last reviewed: 13 October 2026

In short: Rented houses in Ireland must contain a suitable fire detection and alarm system and a fire blanket, and the landlord is responsible for compliance with these standards. Multi-unit buildings have further requirements for common areas. No requirement for owner-occupied homes was found in the sources read.

Notes

  • The 2019 Regulations apply to houses let for rent, with exceptions (for example holiday lettings, some accommodation let by the HSE or approved bodies, and some caravans and mobile homes). A requirement for owner-occupied homes was not found in the sources read; building regulations for new dwellings were not read.
  • Under section 12(1)(b) of the Residential Tenancies Act 2004 the landlord must ensure the dwelling complies with the standards prescribed under section 18 of the Housing (Miscellaneous Provisions) Act 1992 and must repair and replace fittings as necessary. Regulation 10(6) requires common-area systems in multi-unit buildings to be maintained to NSAI standards.
  • The date the 2019 Regulations came into operation (regulation 1(2)). They revoked the Housing (Standards for Rented Houses) Regulations 2017; any earlier start of the fire-safety requirement was not checked. Later amending instruments were not found in the sources read.
