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, Chapter 119 of the Cedar Grove code establishes the "Cedar Grove Construction Inspection Agency" as the township's State Uniform Construction Code enforcing agency, and the Building Department page names no code edition. The township code also still carries Chapter 102, Building Construction, adopted in 1973, which incorporates "The Basic Building Code of the Building Officials Conference of America, Inc., Fifth Edition/1970" with local amendments.

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 Cedar Grove needs one from the township's Building Department, the "Cedar Grove Construction Inspection Agency" under Chapter 119 of the township code, at 525 Pompton Avenue, Cedar Grove, 973-239-1410, ext. 246. Where a roof permit is required, Section 119-3B(4) says "For decks, porches, satellite dishes, communication tower, roofing, central conditioning, fences six feet or over, sheds 100 square feet or more and/or 10 feet in height and any other outdoor structures shall be figured under the alteration fee," and the alteration fee in Section 119-3B(2) is "$50 per $1,000 or part thereof for the first $2,000 of the estimated cost of the work and $25 per $1,000 or any part thereof in excess of $2,000." Plan review adds 5% of the permit fee for alterations in Use Groups R-3 and R-4 and 20% in other use groups. The Building Department page says "No cash will be accepted for any permits." Inspections are by appointment only: "You must call the building department at 973-239-1410, ext. 246, to schedule all inspections." The building inspector inspects Monday through Friday, 1 pm to 4:30 pm.
