A new low-hazard storage and warehouse building of about 71,094 square feet is proposed at 35 South Jefferson Road in the Whippany area of Hanover Township. County records describe it as a storage building.
Trade press reports say the site is a 6.6-acre property with a vacant office building of about 40,000 square feet. The developer, Marcus Partners, is turning it into a logistics building of about 72,000 square feet. That building would have 36-foot ceilings and could be used by one tenant or several. Trade press says the developer broke ground in October 2025 and expected to finish in the third quarter of 2026. No tenant was named in the sources found.
No township meeting records or opposition were found. The press describes a conversion, while the county record calls it a new building. The two may describe the same project, but that was not confirmed.

- A vacant office property would be put back into use, which is the main local effect the sources describe.
