After nearly four years, the Robert C. McEwen Customs House, 127 N. Water St., is again home to the U.S. Border Patrol.
The building has seen a series of renovation projects that have brought the 200-year-old structure into the 21st century, without compromising its historical integrity.
The citys Customs House is the oldest federal building still in active use in the country.
The projects, totaling close to $2 million, installed a separate prisoner and processing unit, room for a canine division, a secure entrance, a waiting area, conference space, locker rooms and an elevator.
The project also saw a new sign installed along with an American flag flanked by U.S. Department of Homeland Security and Border Patrol flags.
The building is managed by the federal General Service Administration.
General Service Administration spokeswoman Renee Miscione said the upgraded heating, ventilation and air conditioning system were installed.
All upgrades were performed at this 200-plus year old building in such a way as to retain the integrity of the historically significant architecture while meeting the current mission and standards of U.S. Customs and Border Protection, Ms. Miscione said.
The Border Patrol were officially moved in Jan. 31.
For the past four years the Border Patrol was renting space from the Ogdensburg Bridge and Port Authority at the port of entry for $60,000 a year.
