Welcome to 20 Nassau!


More than uniquely Princeton, 20 Nassau is uniquely perfect for you.

At five stories and with 70,000 + square feet of space, 20 Nassau is the largest office building in downtown Princeton. Its red brick, Federal-style design is topped with a striking copper mansard (roof). Extensively renovated since 2000, the building has 13 stores and 112 office suites ranging in size from 150 to 450 square feet, ideal for small companies and entrepreneurs, therapy practices, and one- or two-person accounting firms. In addition, 20 Nassau occasionally features larger spaces (above 1500 square feet.)

Location + Amenities

20 Nassau is ready…and it’s right where you need to be.

We’re located at the corner of Chambers Street and Nassau Street, downtown Princeton’s main street.

Our eighteen years of renovations have brought us a new sophistication. The building’s interior hallways and foyers are adorned with large-format art, original sculpture, and bountiful foliage. We’re Wi-Fi ready and equipped with fiber optic Internet infrastructure. The property manager is on-site during 9 AM – 1 PM business hours, and there is a 24/7 emergency contact.


Classic in 1918…classic now.

When 20 Nassau was constructed, just after World War I in 1918, it became an instant Princeton landmark. Over the years it was used as a dormitory. We believe hundreds of Princeton University students called the building home. One can only imagine the conversations that occurred within its rooms. Step outside, and you’re literally in the footsteps of Hamilton, Einstein, and generations of other men and women at the forefront of American business and culture.


Convenience is everything. Everything is convenient.

Long a noted business incubator, 20 Nassau’s neighborhood begins in the building itself where you’ll find doctors, lawyers, architects, accountants, financial advisors, an advertising agency, Internet start-ups, physical therapists, acupuncturists, a massage studio, a barber shop, a yarn and needlepoint shop, an art gallery, and street-level restaurants including a NY deli, a creperie, farm-to-table take-out and more.

Just beyond our front door is Princeton’s very best. Stroll over to Palmer Square in the center of town, or cross Nassau Street to Princeton University and its famed art museum and architecture. For lunches and after-work dining, Princeton’s wide variety of restaurants, from fine dining to quick meals and cafés, is minutes away. For shopping, Urban Outfitters, Ralph Lauren, Lululemon Athletica, Talbots, and Origins are all nearby. And when culture calls, we’re just a short walk from the Tony Award-winning McCarter Theatre.

You and your guests will always have somewhere to park. There are plenty of metered spots on the street, and we’re very close to the multi-level garages in town. We’re minutes from US 1, Interstate 95/295, and Route 206. NJ Transit’s Princeton station and Dinky are a walkable distance away, and NJ Transit’s Princeton Junction (Northeast Corridor) station with regular, frequent service to New York City and Philadelphia. Trenton is only ten minutes away.

Come experience 20 Nassau yourself.
