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 Green Brook Construction Department page says it enforces "the New Jersey Uniform Construction Code along with the ICC and many other codes" and names no edition.

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 Green Brook needs one from the Construction Department, 111 Greenbrook Road, Green Brook, 732-968-1023 ext. 6606, open Monday to Friday, 8:30 a.m. to 4:00 p.m. Where a roof permit is required, Section 9-1.5a.2(a)(6) of the township code as codified reads: "The fee for roofing/siding work, completed on structures of Group R shall be $46 each when the estimated cost of the work is not more than $4,000. The fee for roofing/siding shall be $65 when the estimated cost is more than $4,000. Commercial buildings shall be based on construction cost." Ordinance No. 2024-904, which the township's online code lists under "Adopted legislation that has not yet been incorporated into the Code," rewrites that item: on the ordinance copy the cost tiers are struck and "The fee for roofing / siding work, completed on structures of Group R shall be" $80.00, with commercial buildings still priced on construction cost. The ordinance copy shows no adoption date. The department's page says building inspections run Monday to Friday, 8 a.m. to 2 p.m., and inspection and permit status requests go to 732-968-1023 ext. 6606.
