Landlord Jack Collins has been found guilty and ordered to pay £25,324.60 within two months for failing to maintain a property at Beeston in Yorkshire.
Mr Collins denied exposing vulnerable tenants to substandard housing which included leaving the house with defective fire doors, a broken fire alarm, exposed electrical cables, rotten windows and no heating or hot water. One tenant was left without washing facilities for six months.
Leeds Council ruled that Mr Collins had left tenants in considerable distress, forcing them to live day to day in substandard conditions.
In February 2018 Mr Collins had been prosecuted for offences at the same property and had to pay £8,655 including fines and costs for failing to comply with improvement notices served by the local authority to ensure safety of tenants.
In addition, Collins had been fined on two other occasions in the past two years for poor conditions in his Beeston properties.
Over the four prosecutions Collins has incurred fines and costs totalling £59,217 initiated by the council.
Mr Collins' property on Sefton Terrace is one of two recently designated 'Selective Licensing' areas which is a Leeds Council initiate to improve the standard of rented homes in part of Beeston and Harehills.
From 6 January 2020, any person renting out a property in these areas will need to apply for a licence or they could be fined.
