YOUNGSTOWN — The Youngstown Neighborhood Development Corp. is building three new duplexes in the 3000 block of Glenwood Avenue — with onsite solar panels — as part of its ongoing effort to revitalize the South Side corridor.

The three duplexes — to be located at 3013, 3021 and 3031 Glenwood Ave. — will join two other duplexes already built near them, said Ian Beniston, YNDC executive director.

Construction on the first two duplexes were finished in September and are rented. Each duplex has two, two-bedroom, two-bathroom apartment units that are about 1,100-square feet each.

Each duplex costs about $425,000 to build.

YNDC is building three duplexes — also with two bedrooms and two bathrooms each — but these will have onsite solar panels, Beniston said.

“These are the first housing units of any type that we’ve built that are all electric with the power generated by solar panels on the property,” he said. “I don’t think any of these have been built in the city. It’s part of our effort to increase energy efficiency and affordability. We’re reducing the utility costs.”

Most months, tenants in the duplexes being built won’t have a power bill, Beniston said.

The funding for those duplexes came from the Federal Home Loan Bank of Pittsburgh’s Affordable Housing Program, the Federal Home Loan Bank of Cincinnati’s Affordable Housing Program and Mahoning County, Beniston said.

The site of what will be five duplexes has been vacant for at least two decades, with some parts abandoned for even longer, Beniston said.

YNDC has focused much attention on revitalizing the Glenwood Avenue corridor by building new houses on and just off the street as well as renovating other homes. It also turned a previously vacant and fire-damaged Glenwood Plaza into a location for new businesses as well as other commercial buildings on and near Glenwood Avenue, and purchased the former Foster Art Theatre to eventually turn it into housing and retail space.
