Clifton's ON3 Is Turning the Old Roche Campus Into a Live-Work Destination: What It Means for Home Values

Clifton is in the middle of its biggest transformation in decades, and it is happening on the old Hoffmann-La Roche campus right off Route 3. The site, now called ON3, has been redeveloped into a live-work campus with thousands of jobs, and in July of 2025 the developer cleared the final approvals for a huge new phase that adds up to 1,074 apartments, new retail, a hotel, and more. I grew up in this area and have watched Clifton change my whole life, and I can tell you this project is one of the biggest things to happen to property values here in a long time. Here is what is actually going on at ON3, what it means for Clifton and Passaic County home values, and why buyers and sellers should be paying attention.

What ON3 Actually Is

The site is the former North American headquarters of Hoffmann-La Roche, a 116-acre campus that spans Clifton and Nutley along Route 3. Prism Capital Partners bought it in 2016, and instead of leaving a dead corporate campus behind, they turned it into one of New Jersey's most watched redevelopments. Today the roughly 1.47 million square feet of office and lab space on the campus is fully occupied and home to more than 5,500 professionals. That is not a distant plan. That is happening right now, and it is already the largest mixed-use redevelopment New Jersey has going.

The Companies and Jobs Already There

The roster reads like a map of New Jersey employers. Eisai, the pharmaceutical company, anchors the landmark high-rise with around 330,000 square feet. Ralph Lauren has a major corporate presence. Quest Diagnostics is there. Hackensack Meridian School of Medicine and Seton Hall University's Graduate College of Nursing and School of Health and Medical Sciences bring the academic side, alongside Modern Meadow, Y-mAbs Therapeutics, and the new Hackensack Meridian Health and Wellness Center that opened in July of 2025. Add it all up and you have a campus with real, stable jobs. Jobs are what drive demand for housing, and that demand is what shows up in prices.

The New Housing Phase

The big news for home values is Phase IV. In July of 2025, Prism secured the final approvals to build up to 1,074 multifamily apartments on the Clifton side, along with about 90,000 square feet of additional retail and a 150,000-square-foot research and development facility. Around 200 of those units are earmarked as affordable. This is the first real residential piece of the campus, and it turns ON3 from a place people commute to into a place people live. That mix of jobs, shopping, and homes within walking distance is exactly the kind of environment that pulls buyers to a town.

The Retail Wave Is Already Landing

Retail is arriving fast. Starbucks opened in late 2024 as the first retail tenant. Chase Bank and Chipotle came next, with Chipotle's groundbreaking targeted for late 2025, and Panera with a drive-thru was announced in March of 2026. A 266-room dual-brand Marriott AC and Element hotel with a rooftop bar got its final site plan approval back in July of 2021. Add in the Route 3 improvements and the PSE&G-backed upgrades to the campus power plant, and you have the infrastructure to support all of it. When a neighborhood gets places to eat, bank, and stay, it stops feeling like a business park and starts feeling like a community.

Beyond ON3: Nash Park and Main Avenue

It is not only the campus. Clifton broke ground on a major rejuvenation of Nash Park, the 530,000-square-foot park on Lexington Avenue, with an inclusive playground, ADA-accessible walking paths, restoration of the historic rose garden, an upgraded dog park, and new basketball courts, and a splash pad was dedicated there in May of 2026. At the same time, the city's facade program is helping spruce up the Main Avenue and Botany Village business districts, and the long-planned renovation of Corrado's, the big specialty market on Main Avenue, began in late 2025. These are the quality-of-life upgrades that make a town a place families choose to stay in.

What It Means for Clifton Home Values

Here is how all of this lands on your house. First, jobs and amenities attract buyers, and more buyers against the same supply pushes prices up. Second, the new apartments bring thousands of new residents who want to live near where they work, and many of them will buy single-family homes in surrounding neighborhoods like Montclair Heights and Allwood. Third, redevelopment signals to lenders, appraisers, and the whole market that Clifton is a place worth investing in. Clifton homes are already selling at a median of roughly $600,000 to $640,000 depending on the source, with homes moving in about a month, and this kind of momentum is a big part of why.

The Honest Caveats

I want to keep this real. New supply can also put a lid on rent growth, because more apartments means more choices for renters. And there is still a dispute over Clifton's affordable housing ordinance that could affect how many of the planned units actually get built. Clifton also carries some of the highest property tax rates in the country, so the tax bill is always part of the math. None of that takes away from the direction this town is heading. It just means the smart buyer and seller looks at the whole picture, not just the headline.

The Bottom Line

I have lived and worked in North Jersey my whole life, and I have never seen a single project move the needle in Clifton the way ON3 is. If you are thinking about buying, selling, or investing anywhere in Passaic County, Clifton included, the value story is getting stronger by the quarter. Let me help you put real numbers on it, because the goal is not just to close, it is to help you win.
