Complaints concerning incidents of noise nuisance are investigated on behalf of the Council by Environmental Health Officers (EHOs). These complaints mainly relate to complaints about commercial enterprises operating within Dún Laoghaire-Rathdown County Council’s functional area.

Noise from Construction Works

While there are no set times in law limiting the working hours on building sites, there are guideline standard times that apply to construction activity. If work takes place outside of these hours, it can then be regarded as a source of noise nuisance and investigated by the Council’s EHOs. Site development and building works in Dún Laoghaire/Rathdown are restricted to:

  • Monday to Friday: 7 a.m. to 7 p.m.
  • Saturdays: 8 a.m. to 2 p.m.
  • Sundays & Bank Holidays: Works not allowed.

However, please note that these are guideline times only, and in certain circumstances it may be necessary for building works to take place outside of these hours. In addition, these guideline times do not apply to any kind of emergency works carried out by the ESB, Bord Gais, Iarnród Eireann etc. Construction working hours on a particular development may also be regulated by way of a condition attached to the planning permission and breaches in these cases are enforced by the Planning Enforcement Section of the Council.
