Cork City Council received just 10% of an estimated €1.1 million in fines it levied this year on owners of derelict sites in the city.
Invoices totaling €1,109,324 were issued to owners in 2023, with just over €102,000 collected since January.
There are 147 sites on the Derelict Site Register, up from 109 in 2022, with the local authority in the process of adding a further 55 sites to the Register, today's Cork City Joint Policing Committee was told.
Chief Executive Ann Doherty also told the committee meeting that as of the end of October, Cork City Council has a total of 10,892 units in its housing stock, with 257 of them undergoing repair, and 96 others in the process of being allocated.
In 2023, one tenant had to surrender their tenancy due to anti-social behaviour, while 30 verbal warnings have been issued to tenants this year.
The local authority can only initiate a Statutory Tenancy Warning where evidence exists of an actionable breach of tenancy, the meeting was told.
Details of on-street parking fines were also outlined, with 50,320 tickets issued between November last year and October this year.
Most of the parking tickets were issued on St Patrick Street, mainly for the failure of drivers to display a valid parking disc, while just 0.1% of tickets were issued to motorists for obstructing a cycle track.
In the past six months, some 281 litter fines were issued by wardens, with 68 people successfully prosecuted in the courts.

While those found to be in possession of drugs for personal use dropped by 19% on the 2022 figure - 636 detections down from 789 detections.
47 rapes were reported between January and November 2023 - up 9% from 43 in 2022.
