Roofing in Irvington 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. Locally, the Township of Irvington's Building & Construction page says the department "is designated as State Uniform Construction Code (UCC) Enforcement agency." Chapter 240 of the Township Code (Construction Code, Uniform) sets up the enforcing agency, its fees and its penalties and contains no roofing provision.

Under state law a reroof needs a permit on a townhouse or other attached dwelling, on any other building, and wherever the work reaches the roof structure; reroofing a detached one- or two-family house is ordinary maintenance with no permit (N.J.A.C. 5:23-2.7(c)1.x, "The repair or replacement of existing roof covering on detached one- and two-family dwellings"). Where a roof permit is required, apply to the Township of Irvington's Building & Construction Department, Municipal Building Room 201, 1 Civic Square, main number 973-399-6610; the Township lists its hours as Monday to Friday, 9:00 a.m. to 4:00 p.m. Township Code Section 240-3, as amended through Ordinance No. MC 3915 of September 8, 2025, has no roofing line, so a reroof is priced as renovation work under Section 240-3C(2): "Permit fees for renovation alterations and repairs shall be based upon the estimated cost of the work. Up to $50,000, the fee shall be $45 per $1,000; $50,000 to $100,000, the fee shall be $35 per $1,000 of the estimated cost. Above $100,000, the fee shall be in the amount of $25 per $1,000." Section 240-3 sets a $75 minimum for a basic construction permit. Section 240-6B fines a contractor or owner found doing construction work without a valid construction permit "a minimum of $500 and a maximum of $10,000 or a maximum of $2,000 for each discipline," and Section 240-6C says "You must have the actual permit posted on the property before work is started."
