Amazon looks to lease new Boston office, mayor announces

Amazon is seeking a new office in Boston's Seaport District, a move that could bring 2,000 employees to the city in the next few years.

The company filed documents this week with the Boston Planning and Development Agency to lease a building in the proposed Seaport Square development. Democratic Mayor Marty Walsh formally announced the project Tuesday, saying it puts a "tremendous vote of confidence" in the city's economy.

Amazon and the developer are seeking $5 million in city property tax breaks, which would depend on the company creating at least 2,000 jobs in the area by 2025.

The company included Boston and neighboring Somerville on a shortlist of finalists for its second North American headquarters. The $5 billion project is estimated to generate up to 50,000 new jobs.
