Residents of a block of flats in Cromer say they're upset and angry at being told they have 28 days to get rid of their pets or face legal action.
People living in Clevedon House have been sent letters from Watsons Property of Norwich warning them that the freeholder wants to enforce a 'no pets clause' which has long been ignored.
The letter states: “No bird, dog or other animal shall be kept in the premises without the written consent of the lessor which may be withdrawn at any time.”
Residents have also been warned that failure to comply could: “result in formal proceedings being instructed by a solicitor which could have a detrimental effect on your tenure of the lease and any mortgage product you have in place.”
The news has come as big blow to those who rely on their pets - including Esme Gubbins who says her dog Eddy is a constant companion to her teenage daughter Saleema who has ME and rarely leaves their home.
"She (Saleema) was housebound for a year and slowly she's started to go out," Esme said.
"She will now go out for about 10 minutes a day to walk the dog. We're staying with the dog!"
Some residents admit they were aware of the clause when they moved into their flats, but have never thought it would be an issue.
Alistair Dunnett, who owns the property, told ITV News Anglia that he put a clause in all the leases that flat owners and tenants mustn't keep pets when he bought the block in 2001.
He went on to say that all the flats are old and don't have sound-proofing, but he did admit that in exceptional circumstances he is prepared to look at individual cases.
