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, Borough Code Section 13-1.1 establishes "Watchung Construction Code Department" as the State Uniform Construction Code enforcing agency, and neither it nor the Building / Construction page names an 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 Watchung Construction Code Department, 15 Mountain Boulevard, Watchung, phone (908) 756-6093, ext. 219, takes paper applications only: "Permits can be dropped off to the Construction Department Monday - Friday or mailed to the Municipal Building with attention to the Construction Department," and "we cannot accept incomplete applications." Payment is in the office, "Monday - Friday 8AM - 3:30PM," by check or cash in the exact amount. Inspections are on Tuesdays and Thursdays; to schedule one, call (908) 756-0080, press 2 for Construction, then 1 for Inspections, and "Requests made less than 24 hours in advance will not be filled." Property owners can view basic permit information through an SDL Portal account. Where a roof permit is required, the Borough's posted Construction Fee Schedule lists "Roofing" at a "Flat Fee" of "$65.00" on its building fee pages, and Borough Code Section 13-1.3 sets building subcode fees "in accordance with the fees established by the Department of Community Affairs, pursuant to N.J.A.C. 5:23-4.20."
