1Q office vacancies nudge higher on Long Island.

The office vacancy rate on Long Island crept higher during the first quarter of 2006 as rents also inched up, according to a new report by the commercial real estate services firm Sutton & Edwards Inc./TCN Worldwide.

The overall office vacancy rate for Nassau and Suffolk Counties was 11.07 percent for the 2006 first quarter. That compared with 10.42 percent at the end of the fourth quarter last year and 10.2 percent in the 2005 first quarter.

"There has been a flight to quality," said Sutton & Edwards President Alan Rosenberg, noting demand for Class A space remains strong with most newly constructed office buildings in the region have been completely leased or in the process of being leased. This, he said, will mean continued upward pressure on rents. "Tenants won't object to pricing. They are willing to pay more."

Rosenberg said the demand for Class A space, space in professionally managed buildings with excellent locations, amenities and access, is leading landlords of high-end Class B buildings to upgrade their properties.
