North Norfolk Clinical Commissioning Group wants to replace six respite care beds with a mobile team looking after patients in their own homes.
But campaigners fear this will lead to the closure of the home, where beds commissioned by Norfolk County Council are also under review.
Today North Norfolk council's scrutiny committee voted unanimously to support a motion calling for existing services at Cranmer House to be retained.
The council is also calling for any future changes to take account of the area's increasingly aging population .
In a statement after the meeting, the clinical commissioning group said: 'We are constantly reviewing the patients who use our community beds – this is nothing new.
'However, the way we use our beds has changed enormously in recent years, and it will continue to do so as more people are cared for and supported in their own homes.
'It is also important that we ease pressure on the local health and social care system by keeping beds free for those who need to be cared for in a bed setting.'
