Monroe Township’s own rules
Building permitRequired
New construction and additions under the Monroe Township Construction Office, Williamstown NJ, per the township guide
The guide is dated rev. 7/25/12 and lists the Williamstown construction office; confirm it is current.
Construction may proceed only after the listed approvals (zoning permit, planning board approval if needed, county health approval, utility connection permits) are submitted with the construction permit application.
The checklist is stated to be a general guide, not all-inclusive.
“this checklist represents the general requirements for the submission of a new construction permit application.”
A resident homeowner doing their own work on their own property in Monroe township
The owner signs a certification in lieu of oath stating they are performing the work themselves; the guide warns that this forfeits New Jersey home builder warranty protections.
A resident homeowner may draw plans without a seal; plans for all other applicants must be sealed by a New Jersey licensed architect or engineer.
The guide notes that owners who sign for an unlicensed builder forfeit protection under the law.
