PORTLAND, Ore. -- It’s the 21-story complex towering over the east end of the Burnside Bridge, and it’s tough to miss.

Decked out in dark gray steel and glass, the Yard is set to open for public tours June 18.

A total of 57 of the reported 284 units will be affordable workforce housing, meaning they’ll be available to those making 60 percent of the area's median income.

Rent for those units will start at $734 a month. Market rate units start at more than twice that amount.

Minimum rent for a 500 square-foot studio is listed at $1,500/month. One bedrooms, at just under 600 square feet, start at $1,768/month.

The most expensive unit listed on the Yard’s website is a 2-bed, 2-bath. It’s 1,042 square feet, and it goes for $4,428/month.

At the same time, developers of the new high-rise may be facing some costs of their own.

Ross Caron, spokesman for the city’s Bureau of Development Services, confirms the final project doesn’t match the initial design, approved by the city back in September, 2013.

That design, he says, had significantly more windows near the building’s top.

The problem came when heads at Hood River-based Key Development submitted a separate, standard building permit application in September 2015.

That application contained a revised design, says Caron, that matches the building’s actual exterior.

City staff approved the building permit, not noticing the changes in design.

Now, Caron says officials are “working collaboratively” with Key Development to add more windows to the Yard.

Caron says nothing has been decided as to how many will be added, or how much it will cost.

He confirms the city may help foot the bill for the new windows, by refunding building permit fees, already paid by Key Development.
