Local developer eyes housing for office building in Cedar Knolls near Interstate 287

June 18, 2025

The developer who recently purchased 14 acres containing a roughly 117,000-square-foot office building in Morris County is eyeing potential housing at the site just off Interstate 287.

Whether or not anything comes of the idea remains to be seen. Josh Mann, co-founder of Millburn-based Iron Ore Properties LLC − which recently announced that it purchased the property − said he wants to get a discussion going with local officials and town residents.

The property, 240 and 255 Cedar Knolls Road in the Cedar Knolls section of Hanover, is currently zoned for office and medical, something Mann said would have to be addressed with the local zoning board of adjustment.
