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 Division of the Construction Code Official says it is empowered by the Jersey City Municipal Code to "Administer and enforce the State Uniform Construction Code and conduct the centralized issuance of permits and inspection services," and City Code Section 131-2 (added April 23, 2025 by Ord. No. 25-026) repeats the six-month grace period "In accordance with N.J.A.C. 5:23-1.6 (Grace Period)."

Jersey City's ordinary-maintenance list, which includes reroofing a detached one- or two-family house, is headed "THIS DOES NOT SUPERCEDE HISTORIC APPROVAL REQUIREMENTS," and City Code Section 131-13 says "No permits shall be issued for the alteration, renovation, repair or demolition of a building or structure officially designated and approved as a historic site until such plans are approved by the Historic Preservation Commission." Where a reroof needs a permit, the application, payment and inspection requests go through the City's online customer portal, which also takes Historic Preservation applications. The Division is at the City Hall Annex, One Jackson Square (364 MLK Drive), phone (201) 547-5055; office hours are 9:00 a.m. to 4:30 p.m. and the permit counter is open 9:00 a.m. to 3:00 p.m. The Division states that "Construction Site Work Hours are Monday thru Friday 7:00am-6:00pm (Excluding Federal Holidays)." A dumpster permit is a separate application to the City's Department of Infrastructure.
