Hopes are high in Long Island City that Amazon’s plan to open a new headquarters there will bring tens of thousands more residents to a Queens neighborhood that was once heavily industrial but now has a mix of rowhouses, shiny towers, and a slowly growing collection of residential staples like grocery stores and pharmacies.

The first Amazon employees will arrive in January, but because the company will add them gradually, with a goal of 40,000 hires by 2034, Long Island City won’t exactly balloon overnight. And of course, some employees will decide to find a home in another area anyway.

Long Island City has been one of the busiest neighborhoods for new construction in New York, according to Localize.city, a building data site. In the first six months of 2018, about 3,000 apartments were completed, representing about a quarter of all the new units in the city, and another 3,300 apartments are expected to come to market there by 2020.

But in the weeks since announcing its move — one marked by contention over $1.525 billion in financial incentives from the state of New York — Amazon has already had an impact on Long Island City’s residential market, according to brokers, developers and residents.
