Executive Summary

399 Campus Drive presents a Class A office investment opportunity with significant value-add potential in Somerset, NJ. The property encompasses approximately 126,000 square feet on a 7.57-acre parcel and currently offers a large block of availability totaling ±78,000 square feet. Occupancy stands at 34.2%, providing investors room to capture upside through lease-up or redevelopment strategies.
Recent capital improvements include a new roof, replacement of most HVAC systems, upgraded restrooms, and renovations to the lobby and common areas. Tenants benefit from an enhanced on-site experience that includes a fitness center and tenant lounge. Positioned at the convergence of major highways and regional corridors, the property offers direct access to Route 22, the NJ Turnpike (Exit 10), Garden State Parkway, and Interstate 78, ensuring outstanding transportation connectivity.
Located in a high-income labor market, the property sits near major employers such as Johnson & Johnson, Regeneron, RWJ Barnabas, and SHI, offering a strong base of corporate activity. Pending approvals for an industrial redevelopment plan provide an additional avenue for investment flexibility, which includes a proposed ±120,102 square foot warehouse/distribution project with 22 loading docks. This dual-path potential increases optionality for ownership and enhances overall exit strategies.
