A failing Diss care home began the process of closing down shortly after a regulator report stated it needed to make swift improvements in a set timescale.
The Nunnery, based in Denmark Street, closed on September 30, according to Norfolk County Council.
It was a care home for people over the age of 65 and for those with dementia.
Independent care regulator the Care Quality Commission inspected the home, owned and run by Jane Wentford, on July 16, producing a report on August 23, which highlighted a number of failings.
A spokesman for Norfolk County Council said: “In conjunction with Suffolk County Council we have found alternative accommodation for the 17 residents who were living at the home.”
The spokesman added that although the report was known to the authority, they understood that there were other factor’s which led to the closure of The Nunnery.
A spokesman for the CQC said: “CQC was informed in August that the owner of The Nunnery would be closing the service and that the registration would be cancelled.”
The CQC’s report of August 23, stated The Nunnery needed to make improvements within a set timescale.
They included failing to protecting people against the risks of unsafe care, by not effectively assessing and monitoring the quality of service provided.
It said the home was failing on cleanliness and infection control and therefore increasing the risk of a health care associated infection.
It also stated there was poor medicine management and that adequate records were not being kept.
The CQC said it would make an unannounced visit shortly after, but were told the home would be closing.
The Diss Express was not able to make contact with Mrs Wentford.
