The state has given the Town of Riverhead the go-ahead to convert a National Guard armory into new space for the overcrowded town justice court and police department.
The town’s next step is to determine how much the conversion will cost and how long it will take.
The armory became surplus when several National Guard companies and Army and Marine Reserves centers in Nassau and Suffolk counties were consolidated into a single building in Farmingdale earlier this year.
Last week, Gov. Andrew M. Cuomo signed legislation to transfer the armory to the town.
The building has been vacant for several years.
Preliminary estimates last year placed the cost of conversion at more than $1 million.
The cost would become part of the town’s capital budget and thus not subject to the state’s 2 percent tax cap.
The armory is on Route 58, a few miles from Town Hall.
Town plans call for relocating other scattered departments into the existing police and court building, which is next to Town Hall.
The armory had been used by the 133rd Quartermaster Company of the New York National Guard, which served in Iraq.
Earlier this year, another armory in Nesconset was opened as a public library.
