Derelict Sites

A Derelict Site - means any property/land which detracts, or is likely to detract, to a material degree from the amenity, character or appearance of land in the neighbourhood in question because of neglected or unsightly condition.

What qualifies as a Derelict Site?

The definition of Derelict is set out in the Derelict Sites Act 1990 (as amended).  A site can be classified as ‘derelict’ if it meets the following criteria:

It contains land or structures that are in a neglected or unsightly condition.
It contains dangerous or ruinous structures. (Dangerous or ruinous structures are also addressed under Dangerous Structures legislation, which is managed by the Building Control Division.  Derelict Sites will work with Building Control to use the most appropriate legislation to resolve a problem.)
It has accumulated a lot of litter or other waste due to the vacant nature of the site and illegal public dumping/ littering.

What Happens Next?

Cork City Council will investigate all complaints.  If a site qualifies as derelict, but it is considered that issues can be easily remedied within a relatively short timeframe, Cork City Council may work informally with a property owner instead of serving a legal notice. 

In other instances, the City Council may serve a legal notice requiring works to be carried out, add the property to the Derelict Sites Register (which results in a 3% annual levy on the market value of the property, from 2020 this will increase to 7% of the market value), or even begin steps to acquire a property.
