The county record describes a permit for accessory buildings and miscellaneous structures at 249 Millburn Avenue in Millburn Township. Accessory structures are secondary buildings that support a main use on a site, such as storage, utility or service buildings. The record lists about 106,379 square feet of non-residential space and a reported construction cost of about $2.8 million.
The square footage is large for the stated cost and for the term "accessory." It may count a whole site or several structures together. The record does not say what is on the property now, who will use the structures, or what they are for.
No news coverage, developer page, township agenda or hearing notice was found for this address. Searches turned up other Millburn Avenue projects, but none at this site.
What it could mean nearby
- The records do not say what the structures will be used for, so traffic, jobs and utility effects cannot be judged.
- The record lists no new homes, so effects on schools or housing look unlikely.
Where it stands
The county shows a permit-stage filing dated 2025-03-18. No public hearing or approval was found online. Permits like this are usually reviewed by the township's construction and zoning offices, and the work can then be inspected as it is built.
