A landlord who ignored planning rules and converted two letting properties into flats without permission faces paying a council almost £90,000 in fines and costs.
David Dahan, 65, also has to fork out for the expense of demolishing and rebuilding extensions on both homes to comply with planning restrictions.
Barnet Council, North London, started enforcement action against Dahan when he built an extension on a home in Golders Green, North London, which was larger than plans the council had agreed.
The council ordered him to demolish or make the extension smaller.
When planners returned to check Dahan had complied with the order, they found the building work had finished and tenants were living in the flats.
Another home owned by Dahan was checked, and planners found he had converted the building into 11 flats without permission.
A council investigation revealed Dahan was earning £10,000 a month in rents – and £5,000 was the result of the illegal conversions.
Dahan refused to comply with the council orders, and faced two charges of breaching planning rules.
At Harrow Crown Court, he admitted the offences and was fined £2,000 on each count with £7,000 costs.
The judge also ordered Dahan to pay the council £75,636 under the Proceeds of Crime Act within six months. If he does not, Dahan could go to jail for up to two years.
Councillor Richard Cornelius said: “Dahan showed a blatant disregard for the planning process and made a tidy profit over a number of years from illegally renting these properties out.
“I hope the confiscation of his ill-gotten gains serves as a warning to others that we can, and will, come after anyone who we learn has profited from the proceeds of crime.”
The illegal extension now complies with the original plans, said the councillor.
