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 and Zoning page says "Permits are required when work being performed falls under the jurisdiction of the New Jersey Uniform Construction Code (UCC)" and names no code edition. Chapter 195 of the Township Code sets up the local enforcing agency to carry out the State Uniform Construction Code Act and adopts no building code of its own.

Under state law a reroof needs a permit on a townhouse or other attached dwelling, on any other building, and wherever the work reaches the roof structure; reroofing a detached one- or two-family house is ordinary maintenance with no permit (N.J.A.C. 5:23-2.7(c)1.x, "The repair or replacement of existing roof covering on detached one- and two-family dwellings"). The Township's Construction and Zoning page says the same in its own words: "No permit is required for what the state defines as ordinary maintenance." Where a roof permit is required, Section 235-6 of the Mine Hill Township Code lists "Roofing and siding" at "Group R-2, R-3, R-4, flat fee: $250" and "All other groups: cost of construction per $1,000," with a plan review fee of "25% of the amount to be charged for the construction permit" and a $50 minimum for a basic construction permit. Applications go on the state permit forms (the construction permit jacket and the subcode technical sections), with "A copy of the contractor(s) license" where applicable, and are dropped off at the Construction Department at the Township offices, 10 Baker Street, Mine Hill. An approved permit "will need to be picked up and paid for by check or cash between 9:00 a.m. and 4:30 p.m. Monday through Friday." Inspections are scheduled with the Construction Department at 973-366-9031 ext. 4 or through the Construction Permit Portal the page links.
