The Erie County Industrial Development Agency agreed Tuesday to move its office to the Perry Street building that currently is home to Empire State Development’s Buffalo office in a move that officials said will create a one-stop shop among the region’s main economic development agencies.

The ECIDA approved the move a little more than five years after the agency backed away from a similar initiative because of concerns about space needs.

The Buffalo Urban Development Corp. and the Binational Economic Alliance also are expected to join the ECIDA in moving their offices from Genesee Street to the fourth floor of the building at 95 Perry St. The agencies will share boardroom space with Empire State Development and the Erie Canal Harbor Development Corp. on the fifth floor.

“This move creates a critical mass of economic development agencies and will give businesses access to a wide range of services, helping them to find what’s available quickly, without spending time and effort traveling from office to office,” said Erie County Executive Mark Poloncarz.

The move will make it easier for development officials to showcase the Buffalo Niagara region to businesses interested in locating here and will provide a one-stop shop for all companies looking for economic development assistance, he said.

The World Trade Center Buffalo Niagara also will consider moving its offices to the Perry Street building once its lease expires at its current site at 725 Main St., said Chris Johnson, the trade group’s president who also serves as the ECIDA’s vice chairman.

The ECIDA, the Urban Development Corp. and the economic alliance currently have offices in a building at 143 Genesee St. that is owned by the ECIDA. Agency officials said they would consider leasing out its Genesee Street office or selling the facility. It previously sold most of its complex to Enterprise Charter School.

A lease agreement between Empire State Development and the Urban Development Corp. still needs to be approved. If that happens, both the ECIDA and the Urban Development Corp. are expected to move into the Perry Street building this summer.

Under the plan, the IDA would lease 6,143 square feet of space with access to another 4,578 square foot of common area on the fourth floor. The mixed-use building at 95 Perry St. is owned by Savarino Cos. and includes apartments and a restaurant.
