Firm Secures Two Leases in Millburn and Denville, NJ
Milburn and Denville, N.J. [Oct. 15, 2025] – Resource Realty of Northern New Jersey (RRNNJ) has secured two new office leases, one of which involves a newly constructed office space in downtown Millburn. The second involves Professional Plaza at 3155 Route 10 in Denville, a major Morris County retail corridor with proximity to Downtown Denville, a Main Street America district.
“Small- and mid-sized businesses are increasingly seeking out properties that offer high-walk-score access to lifestyle services, restaurants and entertainment,” said RRNNJ Principal Brian Wilson, exclusive leasing agent for the Millburn property. “It’s about creating a workspace that serves as an anchor for and extension of vibrant live-work-relax communities.”
Located at 378 Millburn Ave., the mixed–use building is located in the heart of Downtown Millburn, a walkable three blocks from the train station. The entire 5,000 SF second floor was leased to a national real estate company, showcasing the strong demand for Class A office space in the region.
The two-story property features street-level retail options, electric–vehicle charging stations and elevator access, providing tenants with substantial flexibility and convenient access to local amenities. Millburn, a southwestern suburban township in Essex County, is part of what is commonly referred to as the Short Hills region.
Convenient to Routes 24 and I-78, not far from both NJ Turnpike and Garden State Parkway, the town is recognized for its highly-ranked school system, unique specialty shops, award-winning dining, green space and Papermill Playhouse.
Wilson, who brokered the transaction on behalf of the landlord, added that the surge in demand for downtown office space is being driven by businesses of all sizes looking to foster a company culture that balances convenience with community.
“Several municipalities across Northern New Jersey offer the complete package for businesses – a blend of top-tier amenities with seamless access to regional transportation networks, all supported by the strong demographics that make the region attractive for owners and tenants across the professional services sector,” added Wilson.
In Denville, Wilson and Principal Greg Sabato represented the landlord, Woodmont Properties, in arranging a new lease on behalf of a medical-related services provider. The unnamed tenant is joining the high-profile building’s roster of healthcare-related tenants, including physician practices, community heath providers, dental and other ancillary services.
“Properties of this caliber, with their high visibility and demographic strength, are becoming increasingly vital for businesses looking to grow their customer and talent base in a well-established community such as Denville and the surrounding areas,” said Sabato.
Professional Plaza is located along one of the busiest corridors in the state surrounded by sought-after Morris County suburbs, from which employers attract the highly educated labor pool. The 3155 Route 10 property is located less than three miles from two train stations and has more than 150 parking spaces.
