The Project
“Designed to be Lived In. Finished to be Admired.”
Four buildings.
Eight homes.
Four boutique buildings, built from the ground up on one of Union City's most storied blocks. Each address — 421, 423, 425 and 427 Sixth Street — holds exactly two condominiums: a full-floor Residence and a duplex Penthouse crowned by its own planted roof terrace.
New construction with a designer's hand. Red and gray brick facades, with Juliet balconies facing the street. Every home comes with its own two-car garage at street level — sixteen parking spaces across the eight residences.
Inside, wide-plank white oak floors, waterfall islands and a considered material palette carry through every room. Each building carries its own finish package — so the facade tells you which home is yours before you ever walk through the door.

Eight homes in total, from $899,900. Four are on the market today and private showings are open.

The facade tells you which home is yours.
Each building was designed as one piece — the brick outside decides the hardware, the wood and the tile inside. Drag the handle to see the same penthouse kitchen in both.

There is one Penthouse in each of the four buildings, so four in total. The two currently listed are priced at $1,499,900.
Which Union City condos have private rooftop terraces?
Each of the four Penthouses at 421–427 Sixth Street opens onto its own planted roof terrace, reached by interior stairs from inside the home. The terraces face the Hudson and the Midtown Manhattan skyline. The full-floor Residences do not have roof terraces; they sit on the first floor of each building.
What is 421–427 Sixth Street?
421–427 Sixth Street is a boutique new-construction condominium project on the southern edge of Union City, New Jersey, one block from Palisades Avenue. It is developed by Cobo Developers Group and marketed by Cobo Group · Better Homes and Gardens Real Estate Elite. The project is under construction; private showings are open.
How many residences are at 421–427 Sixth Street?
Eight. The project is four separate boutique buildings — 421, 423, 425 and 427 Sixth Street — and each building holds exactly two condominiums: one full-floor Residence and one duplex Penthouse. That makes four Residences, four Penthouses and four private roof terraces across the row.
What is the difference between a Residence and a Penthouse?
The Residence is a single-level home on the first floor: 3 bedrooms, 2 baths and about 1,100 square feet, with a kitchen that runs along one wall into a seated peninsula. The Penthouse is a duplex on the top two floors: 5 bedrooms, 4.5 baths, about 2,211 square feet, a waterfall-island kitchen and a private roof terrace.
Who is the developer and the listing brokerage?
The developer is Cobo Developers Group, at 781 North Avenue, Cranford, NJ 07016. The listing brokerage is Cobo Group · Better Homes and Gardens Real Estate Elite, at 181 North Avenue East, Cranford, NJ 07016. The listing agents are Sebastian Orozco and Ryan Longo, with Christian Cobo as broker and owner.
How close is the project to Hoboken and the 9th Street light rail?
Sixth Street sits at the southern edge of Union City, steps from the Hoboken city line. The nearest Hudson-Bergen Light Rail station is 9th Street–Congress Street, reached by a free public elevator that runs up the face of the Palisades. NJ Transit buses run to Port Authority and the NY Waterway ferry departs from Port Imperial. We do not publish travel times we have not measured.
Do the condos come with parking?
Yes — a two-car garage with every home. Each of the four buildings opens at street level to private garages behind glass-and-steel doors, and both the Residence and the Penthouse in each building get two spaces. That is sixteen parking spaces across the eight homes, which is rare for new construction in Hudson County.
How much do the condos cost?
The four homes currently listed are priced at $899,900 for a full-floor Residence of 3 bedrooms and 2 baths, and $1,499,900 for a duplex Penthouse of 5 bedrooms and 4.5 baths with a private roof terrace. Prices are as listed and can change. There is no confirmed delivery date we are prepared to publish.
