Jersey City Urby, the tallest residential building in New Jersey, has taken another step toward opening.

The 69-story building with cantilevering floors, at 200 Greene St. in Downtown Jersey City, has opened its on-site leasing office and launched its initial phase of leasing.

Jersey City Urby will feature 762 studio and 1- and 2-bedroom apartments. Studios will start at $2,000, 1-bedroom units at $2,300 and 2-bedroom units at $3,400. Occupancy is expected to begin in early April, officials said.

Co-developed by Ironstate Development and Roseland Residential Trust, Jersey City Urby stands 713 feet tall, surpassing the Trump Plaza Residences (532 feet) on Morgan Street.

It will hold the "tallest" title until Journal Squared and 99 Hudson are completed. When finished, 99 Hudson is expected to rise 900 feet and 79 stories, while one of the Journal Squared towers is projected to be 70 stories. Officials with both projects have said the projects will be done by 2019.

Jersey City Urby is the second of a planned series of Urby developments. The first Urby opened in 2016 in Staten Island and a new location will open later this year in Harrison, officials said.

Urby will include communal spaces that host classes, events and unique experiences. Other amenities include:

-- Fully equipped gym, offering regular classes, from cardio to strength training to yoga and barre, taught by certified trainers from Jersey City luxury health club Base;

-- Heated outdoor pool and a deck that will host sunset events, lawn game tournaments, meditation and more;

-- A communal kitchen will be home to cooking demonstrations by local chefs, pop-up dinners, tastings and talks;

-- Urby Creative Lab will be designed to cultivate curiosity, will be a space for residents to participate in hands-on activities, including interior design workshops and flower arranging;

-- 9 Bar Cafe coffee shop will be located on the building's first floor and serve as a lobby lounge.
