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 Township's Construction Office page says the office "enforces the regulations of the Uniform Construction Code (UCC) of the State of New Jersey" and refers readers to the Department of Community Affairs for "the applicable codes in effect."

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 Raritan Construction Office, One Municipal Drive, Flemington, 908-806-6100 (the Township's main number; the Construction Office page lists the Construction Official at ext. 2245), open 7:30 a.m. to 3:30 p.m., Monday through Friday. Where a roof permit is required, the Township's fee section (Code Section 230-3) prices it: "All roof replacements and overlays shall have a flat fee of $50 for the R-3 and R-5 Use Groups, and $30 per $1,000 of the estimated cost for all other use groups." The Township takes paper applications, with the forms posted on its website and three-part forms and permit jackets available at the office. Its checklist asks for the construction permit application, the original plus two copies of each applicable subcode technical section, "One copy of a State Home Improvement Contractors License for all general contractors," and an approved zoning application where the work needs zoning approval: "Applications will not be accepted if the approved Zoning is not included." To schedule a permit inspection, call 908-806-6114.
