Roofing in Commercial Township, New Jersey

Not required

Required

The 2024 International Residential Code, New Jersey edition, adopted by the State, with the Rehabilitation Subcode for work on existing buildings. New Jersey has one construction code, the Uniform Construction Code (N.J.A.C. 5:23), which every municipality enforces; municipalities do not adopt building codes of their own (N.J.S.A. 52:27D-123.1 and 52:27D-139). N.J.A.C. 5:23-3.21(a)1 adopts the International Code Council's "2024 International Residential Code known as the IRC/2024 as the one- and two-family dwelling subcode in New Jersey subject to the modifications stated at (c) below," and 3.21(b) applies it to "detached one- and two-family dwellings and townhouses not more than three stories above grade plane in height." The section was rewritten by R.2026 d.086, "effective August 17, 2026," in the Department of Community Affairs' print of the rules "adopted and published through the New Jersey Register, Vol. 58 No. 16," and the Department's Current Construction Codes page lists the "International Residential Code/2024, NJ ed" with an adoption date of Aug 17, 2026. Other buildings fall under the building subcode, the International Building Code/2024, NJ edition (N.J.A.C. 5:23-3.14). Roof work on an existing building is held to the Rehabilitation Subcode: "Existing structures, when repaired, renovated, altered or reconstructed, shall conform to the requirements of N.J.A.C. 5:23-6, Rehabilitation Subcode" (N.J.A.C. 5:23-2.4(a)). A six-month grace period follows the adoption. N.J.A.C. 5:23-1.6(a): "For a period of six months following the operative date of a subcode revision, applicants may submit a complete permit application, including all prior approvals, to be reviewed under the code in force immediately preceding the subcode revision." The rule history gives R.2026 d.086 no date other than its effective date, so on that reading the window runs from August 17, 2026 until about February 17, 2027: a complete application filed inside it may be reviewed under either the prior edition or the 2024 edition, at the applicant's choice, and one filed after it closes is reviewed under the 2024 edition. Everything above is New Jersey state law, the same in every municipality. The township's Construction page (commercialtwp.com) and Chapter 131 of its code, Construction Codes, Uniform, state nothing further on roofing.

No permit is needed under state law to reroof a detached one- or two-family house; a townhouse, other attached dwelling or any other building in Commercial Township needs one from the township construction office. The State's roster of construction officials, as of September 02, 2026, lists the office at 1768 Main St, Port Norris, phone 856-785-3100. The township's Construction page says "Construction permits are required for all interior and exterior construction work on all structures" and "Homeowners should contact the Building Department for information on obtaining a permit prior to starting the project." It adds that "A survey of the property and a zoning application are required before a permit can be issued for any exterior projects, or an expansion of a primary structure," and that the zoning application goes to the zoning official first. Where a roof permit is required, Chapter 131 of the township code prices building work on renovation, alterations and repair at "$40 per $1,000 in estimated costs for all residential use groups," with a $100 minimum, and $50 per $1,000 for other use groups, plus a plan review fee of 20% of the construction permit fee; it has no separate roofing line. Inspections need at least 24 hours' notice and are scheduled at extension 320. The office is open Monday to Wednesday 8:00 AM to 5:30 PM and Thursday 8:00 AM to 4:30 PM, and is closed Fridays.
