What's Being Built in Morris County: A 2026 Development Roundup
A sourced survey of the housing, redevelopment, warehouse, and public-construction projects reshaping the county — and the infrastructure questions following close behind.
The clearest picture of where development stands in Morris County comes from the county's own ledger. On March 26, 2026, the Office of Planning and Preservation released its 2025 Development Activity Report, and the figures describe a year of unusually concentrated growth — driven by a handful of very large projects rather than a broad spread of small ones.
The year in figures
Planning director Joseph Barilla presented the report to the Board of County Commissioners. The county noted that four projects alone accounted for more than 60 percent of the proposed units, and roughly 14 percent were designated for age-restricted or assisted-living housing. Parsippany-Troy Hills again led all municipalities with 26 submissions, followed by Randolph Township with 18 and Hanover Township with 17. New single-family subdivision activity continued its long decline, with just 23 new lots proposed.
Two themes frame everything below. Affordability remains a pressure point — the county reported a 2024 median sales price of $773,858 for new attached homes and $1,012,840 for detached homes, with median two-bedroom rent at $2,216 a month. And the dominant structural trend is the conversion of aging office campuses and commercial sites into mixed-use residential, retail, and industrial space.
The marquee redevelopments
The District at 15Fifteen
The county's headline example of the office-to-residential shift along the Route 10 corridor. A former office campus redeveloped into a mixed-use district: the residential apartments are completed, while retail shops and a hotel component remain under construction.
Highline Marketplace
A multi-tenant commercial redevelopment on the Sylvan Way office corridor, with Phase 1 construction underway. The broader site has been reported in connection with a large residential and amenity component — on the order of 280 luxury apartments with a fitness club — reflecting the same campus-to-mixed-use pattern.
Morris Marketplace
Built on the former Colgate-Palmolive corporate campus, this lifestyle-retail center delivered more than 140,000 square feet of retail and has opened to tenants. It sits within a larger parcel envisioned to add townhomes and rental units near Mennen Sports Arena. (A separate project from Highline Marketplace, despite the similar name.)
Large residential applications
71 Bassett Highway
One of the larger single proposals in the pipeline: demolition of an existing commercial building and construction of three mixed-use buildings with 640 residential units and 11,733 square feet of commercial space. The filing pairs the housing with roadway, parking, drainage, utility, and stormwater work, and states it would include affordable housing.
Mount Kemble Avenue Redevelopment Plan
The township adopted an amended redevelopment plan covering 9.2 acres and allowing 139 multifamily or townhouse-style units, including 23 affordable units. Township materials list additional affordable-housing sites at 300 Madison Avenue, 100 Southgate Parkway, and 291 James Street.
High Pointe at Florham Park
National homebuilder Lennar announced High Pointe at Florham Park as part of a broader Northeast expansion, offering luxury townhomes in the borough, with delivery slated for fall 2026.
104-unit housing project
A 104-unit Lincoln Park housing project was selected for New Jersey's permitting-dashboard pilot, a state program intended to make project permitting status more transparent to the public.
Earlier-cycle projects still in the picture
Prior-cycle reporting named several redevelopments that remain relevant context: Parq Parsippany (office-to-residential), KRE East Hanover (reported at roughly 239 multifamily units and 309 townhomes), and two Morristown train-station efforts, Morristown Plaza and Morristown Station. Current status on each should be confirmed against municipal agendas.
The big-footprint proposals
Riverdale Quarry redevelopment
The single largest non-residential item in the 2025 numbers — nearly 1.2 million square feet of proposed warehouse space, the main reason county-wide non-residential submissions jumped to about 1.8 million square feet. The site is the long-running Tilcon/Riverdale granite quarry; the borough's master plan has long contemplated reclaiming the quarry as it nears the end of active life.
Former BASF site
A redevelopment of the former BASF site into a roughly 585,000-square-foot warehouse, illustrating the continued conversion of legacy industrial sites along the western highway corridors.
What the public sector is building
Morris County Courthouse project
A major county facility project is reshaping the downtown street grid. In March 2026 the county issued road-closure notices for Schuyler Place, citing excavation, sanitary connections, and a water-service connection for the new courthouse facility.
Morris School District bond referendum
The district is moving toward a bond referendum covering facility needs across its 10 schools, including HVAC and communications-systems upgrades. The district frames the work around long-standing building needs, though the timing overlaps with area housing growth and questions about school capacity.
2026 Capital Spending Plan & trail grants
The Board of County Commissioners presented a 2026 Capital Spending Plan in December 2025 covering infrastructure, public safety, and education across all 39 municipalities. Separately, the county opened its 11th annual Trail Construction Grant cycle, making more than $1 million available to municipalities, with updated rules approved January 7, 2026.
Several of the largest applications — Dover's 71 Bassett Highway, the Morris Township redevelopment plans — explicitly bundle utility, drainage, and stormwater work with their housing. That pairing is itself a signal of where the pressure points are, and where the next round of public hearings is likely to focus.
Housing is moving. Can the systems keep pace?
Across the individual projects, county and municipal records point to a consistent secondary story. The conversation has shifted from whether more housing is coming to whether the surrounding systems — roads, sewer and water connections, parking, stormwater infrastructure, and school capacity — can keep pace once approvals turn into occupancy.
This roundup is built from the Morris County Office of Planning and Preservation's 2025 Development Activity Report and the county's accompanying announcement; municipal planning board exhibits and redevelopment-plan materials from Dover and Morris Township; county road-closure and capital-plan notices; and developer and trade-press reporting. Proposed unit counts and square footage reflect application-stage figures and may change through the approval process. Keep Up Local reports development from public records and official statements, and does not assert outcomes that the record has not yet established.
