Last updated: June 2025
New Jersey Bottom Line: A permit is required in all New Jersey municipalities. NJ uses a unique subcode system — electrical and construction subcode permits are both typically required. Fees: $200–$450. Review time: 1–3 weeks. PSE&G and JCP&L handle utility interconnection (3–5 weeks).
How New Jersey Battery Permits Work
New Jersey operates under the Uniform Construction Code (UCC), which is administered by local construction officials (not called 'building inspectors' in NJ). For a home battery installation, you typically need both an Electrical Subcode permit and a Construction Subcode permit. This dual permit requirement is unique to New Jersey among major states.
The Permit Process
NJ permits are filed with your local Construction Official's office. Most NJ municipalities now have online filing through the NJ Department of Community Affairs portal or their own systems. The dual subcode requirement means two separate approvals and potentially two separate inspections. PSE&G covers northern/central NJ; JCP&L covers parts of NJ; Atlantic City Electric covers South Jersey — each has its own interconnection application process.
What Documents You Need
New Jersey requires: Electrical Subcode permit application, Construction Subcode permit application (for structural attachment), single-line diagram, UL 9540 spec sheets, NJ licensed electrical contractor information (NJ Board of Examiners of Electrical Contractors license), and installer UCC registration.
