Having a bunch of noisy Polish neighbours renting a few doors away, I feel your pain. By the way I have nothing against Eastern Europeans, but don't want to spend my summer listening to their choice of music even when I'm indoors with the windows closed. The police have come around a couple of times when they've been phoned at 1am, but this is a 24/7 nuisance.
I've come up with this http://www.environ.ie/en/Environment/NoisePollution/ on the Dept. of Environment website, some of which says
Noise Pollution - Neighbourhood/Domestic
Noise nuisance caused by neighbours makes up the vast majority of noise complaints in Ireland. Once again, the source of a neighbourhood noise complaint most often dictates the way it should be addressed, depending on whether the individual causing the noise nuisance is a private rented tenant, a local authority tenant or a private home-owner.
Private Rented Tenants:
In the case of noise nuisance being caused by individuals in private rented accommodation, the Residential Tenancies Act 2004 imposes minimum statutory obligations on landlords and tenants of private residential tenancies. Tenant obligations under the Act include an obligation not to engage, or allow visitors to engage, in anti-social behaviour which is defined as including persistent noise that interferes with the peaceful occupation of other dwellings in the neighbourhood. The Act also imposes an obligation on landlords to enforce the tenant obligations.
There is provision in the Act for third parties who are adversely affected by a failure on the part of a landlord to enforce tenant obligations to refer a complaint to the
Private Residential Tenancies Board in accordance with the procedures in the Act. If an alternative legal remedy, such as the remedy provided for under the Noise Regulations (see below) is being pursued then the PRTB cannot intervene.
Since December 2004 all privately-rented properties must be registered with the PRTB. You can check if a property is registered by contacting the PRTB."
The Private Residential Tenancies Board has a website:
www.prtb.ie and they can be contacted at 01-888 2960 from 10am - 1pm and 2pm - 4pm weekdays.
