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 Construction Department page says it enforces "the regulations of the State Uniform Construction Code, which was established by the State of New Jersey" and names no edition of its own.

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 needs a permit. The Borough of Mount Arlington Construction Department page names no roof work in its list of work that needs a permit and asks owners to call if unsure. It also says "In general all improvements require zoning review before work may begin even if the project is exempt from construction permit requirements"; it does not say whether a reroof is such an improvement, and it gives the zoning fees as "Zoning permit application review fee is $50 and the permit fee is $100." Where a roof permit is required, Borough Code Section 67-5A(3) charges "$32 per $1,000 of estimated cost of work, provided that the minimum fee shall be $70" for renovations, alterations and repairs, and the department page says "All payments must be cash or check, no credit card." The Construction Department is at 419 Howard Boulevard, Mount Arlington, NJ 07856, open Monday to Friday, 8:30am to 4:30pm, and answers at 973-398-6832 ext. 114. Inspections are booked by phone at that number, and "Your permit number is required for all inspection requests." The State's directory of construction offices lists the office at the same address with the phone 973-398-0974.
