The Blake will create between 80-100 new jobs at full occupancy, according to a news release.
"It's a crown jewel for Kingsport," Sullivan County Mayor Richard Venable said of The Blake.
"It's a great place to eat with your friends and make new friends," said Kingsport Mayor Pat Shull.
The 110,000-square-foot, $21 million development has 70 assisted living units and 48 memory care units.
"I've had many sleepless nights getting to this point," said Nicole Briggs, The Blake's executive director. "But I can say my team has been phenomenal on this journey."
The Blake offers customized care for every resident, developed with the resident, family members and medical professionals.
Residents have their own dining room, spacious living areas and a secure landscaped courtyard.
