All 62 apartments have been rented at Niagara City Lofts, the new name for the redeveloped former South Junior High School in Niagara Falls.
Mayor Paul A. Dyster announced full occupancy Monday for the site, which opened six months ago. The building at 561 Portage Road was converted by CB Emmanuel Realty of Queens at a cost of $20 million.
Incentives included $6.4 million in state tax credits and $5 million in RestoreNY grant funding.
The school closed in 1987. Niagara Falls voters approved the sale of the property by the Board of Education in a December 2013 referendum.
Tearing down the building would have cost an estimated $1.2 million. City officials estimate Niagara City Lofts will pay $377,000 in property taxes over the next 15 years.
