All 45 apartments in block B of Hue Court have been designated to essential workers like doctors, nurses and social workers.
The high-rise building has recently undergone a major refurb to meet Decent Homes Standards.
Former residents have all been re-housed in Andium properties elsewhere.
"Independent reports from both the Care Inquiry and the Care Commission told us that we need to provide better quality accommodation for key workers in our public services to reduce the high turnover of staff in some areas of health and social care.
"Providing good quality homes will help Jersey to attract and retain high-quality professional workers who can then maintain a sustainable workforce and provide a more consistent service for the island.
"The redevelopment of Hue Court demonstrates our continuing commitment to fulfilling the recommendations of the Independent Care Inquiry, while still housing more Islanders in the new or refurbished homes that are being developed by Andium.” - Senator Sam Mezec, Minister for Children and Housing.
Specialist consultancy firm Altair was appointed commissioned by the Housing Policy Development Board last April to carry out research to inform the Keyworker Accommodation Strategy.
"We are pleased to have helped provide this solution for keyworkers at Hue Court. 48 units of accommodation have already been provided at Plaisant Court and these newly refurbished homes will add to the high-quality accommodation that is now available to the professionals we need to keep our public services operating efficiently." - Sir Mark Boleat, Chair of Andium Homes.
