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 Millstone Construction Department page says its inspectors review work "to ensure compliance with IBC 2021, IRC 2021, NSPC 2021, NEC 2020, NFPA 2020, IFG 2021 and State Uniform Construction Code"; it does not name the 2024 edition. Chapter 14 of the Township Code establishes "a State Uniform Construction Code enforcing agency to be known as Millstone Township Enforcement Agency" and names no code 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 one from the Township of Millstone Construction Department, 470 Stage Coach Road, Millstone Township, NJ 08510, phone 732-917-2953, open Monday through Friday, 8:30 a.m. to 4:00 p.m. Where a roof permit is required, the Township's forms page posts an "Application Check List For New And Re-Roof Permits Residential" (Rev. 9/09) that asks whether the old roof is ripped off or a second layer added, whether the existing roof is wood shingled, whether ice shield is installed, whether six fasteners per shingle are used where eaves are more than 20 feet above grade, whether the shingles are ASTM D-3161 approved, and the total number of squares and of existing roofs. Section 5-14 of the Township Code (most recently amended September 3, 2025 by Ord. No. 25-10) lists no separate roofing fee: "The building permit fee for renovations, alterations and repairs shall be computed on the estimated cost of construction as follows," at "$0.040 per cost of construction," and "The minimum fee for a building permit shall be $80 for residential and $135 for commercial." Plan review is 25% of the permit fee, and the department page says that starting September 8, 2026 plan review fees "will be collected at submission." Permit applications, payments and inspection requests can be made online through the Township's GovPilot portal; "Inspection requests must be received by 1:00 pm to receive next day inspections (if possible)."
