Monaghan County Council is responsible for dealing with derelict sites

The Derelict Sites Act, 1990 allows the local authority to prosecute owners who do not comply with notices served, to compulsorily acquire land and to carry out necessary work themselves and charge the owners for the cost.

The Local Authority also keeps a register of derelict sites: Derelict Sites Register June 2024

What is a derelict site?

Legally, “derelict site” means any land which detracts, or is likely to detract, to a material degree from the amenity, character or appearance of land in the neighbourhood of the land in question because of—

(a) the existence on the land in question of structures which are in a ruinous, derelict or dangerous condition, or

(b) the neglected, unsightly or objectionable condition of the land or any structures on the land in question, or

(c) the presence, deposit or collection on the land in question of any litter, rubbish, debris or waste, except where the presence, deposit or collection of such litter, rubbish, debris or waste results from the exercise of a right conferred by statute or by common law.

What if my property is a derelict site?

You are required by law to make sure your property does not become derelict or you may become liable for prosecution by your local authority.

Monaghan County Council will advise you through a series of statutory notices on what action is needed and necessary works on your site or if your property is being added to the Derelict Sites Register.

The local authority can apply a financial penalty on you. This could amount to 7% of market value of your derelict site for every year it remains on the Derelict Sites Register.

In some cases, a compulsory acquisition may be pursued.
