QUEENSBURY — A senior independent living center has such a long waiting list that it is expanding.

The owners of Cedars Senior Living Community want to add 32 more units to the site at 35 Evergreen Lane.

“We’ve been at 100 percent occupancy for 10 years, with a long waiting list,” said CEO Thomas Getz. “Demand for these units is huge. It’s been a tremendously successful project.”

But there’s only enough room at the site for one more small building. Officials would love to expand further if they can buy more land nearby, he said.

The Planning Board reviewed the concept for a new building at the site Tuesday and had no concerns, but the project has not yet been formally approved.

The company, Green Mountain Development Group, prefers to cluster its buildings together to gain an economy of scale, Getz said. So the company is less likely to buy land far from the current site, which limits its options.

“You need that critical mass in order to support having the services on site and keeping the rents low,” he said.

Seniors usually start with an independent apartment at the center, which has both one and two-bedroom apartments.

“Our model is independent senior living with optional supportive services,” Getz said. “There’s no big entry fee. Some folks just use it as an apartment. They don’t need services yet.”

When they do, they can start getting meals, housekeeping or relying on the center’s buses for transportation.

Rents are also capped, based on income, ranging from $613 to $870 with utilities included. Very low-income residents can pay as little as $367 a month, including utilities. For every resident, the company also offers cable and telephone at a special discount rate.

Residents must be at least 55 years old, with an income of no more than $26,940 for one person or $31,440 for two people. Very-low income residents must have an income of $13,500 or less for one person or $16,240 for two people to qualify for the $367 rent.

Cedars is the only facility in New York owned by Green Mountain Development Group. They are mostly in Vermont and New Hampshire, where they own 800 units and manage 500 others. Those facilities are also popular.

“Our senior portfolio averages 99 percent occupancy with a waiting list, and has for a long time,” Getz said.

The center is also supported by the New York State Low Income Housing Tax Credit Program. That program offers dollar-for-dollar state tax reduction on new construction.
