The Health Information and Quality Authority has revoked a threat to close the Áras Attracta residential care home in Co Mayo.
The decision follows a series of new inspections at the Swinford facility.
Áras Attracta is home to 75 people with intellectual disabilities.
A report last year found that most residents were experiencing an institutional model of care, with centralised practices and limited or no opportunities for personal development and growth.
The finding led to a notification that would have resulted in the cancellation of the registration of all three centres on the campus.
Since then, HIQA inspectors have found a number of improvements in the management of the centre and care provided there.

But they say a number of areas of concern remain, with several issues relating to non-compliance with regulations.
The latest inspections, which were carried out in January, found that improvements had been made to residents' safety and quality of life since the previous review in May 2017.
Three inspection reports published this morning said revised management and oversight arrangements have been put in place.
Residents were found to have more choice in how they spent their day and were better able to participate in making decisions that affected them, through regular resident and family forums.
But the reports said work still needs to be done to improve quality and safety standards.
More staff training is required and record keeping needs to be enhanced, it said.
HIQA said the HSE has submitted a "satisfactory action plan" to fully address outstanding issues and bring the centres into full compliance with the regulations.
The authority said it will continue to monitor progress, amid concerns about the sustainability of planned improvements.
The Health Service Executive has welcomed the HIQA decision.
The Executive says it is committed to implementing the other required improvements at Aras Attracta by September.
It says it has submitted a new application for registration to HIQA.
The HSE’s Chief Officer for the Western Region, Tony Canavan, thanked staff and management at the Swinford facility for their efforts in making improvements.
He acknowledged that more work needs be done in the coming months and said the HSE is dedicated to sustaining improvements already made there.
