Roofing in Hanover Township, New Jersey

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. The Township of Hanover Building & Zoning page states nothing further on code editions.

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 Hanover Building & Zoning Department, 1000 Route 10, Whippany (mailing address P.O. Box 250), phone 973-428-2462, open Monday to Thursday, 8 a.m. to 4:30 p.m., and Friday, 8 a.m. to 1 p.m. Where a roof permit is required, the Township's code enforcement fee section, Code section 125-5 (last amended March 12, 2026 by Ord. No. 5-2026), prices "Roofing and siding" at "(a) Group R-5, flat fee: $100. (b) Group R-2, R-3, R-4, flat fee: $250. (c) All other groups: cost of construction per $1,000." The cost-based rate for renovation, alterations and repairs is "$35 per $1,000 up to $50,000. From $50,001 and up, the fee shall be $20 per thousand of the estimated cost," with a minimum fee of $150, and "The fee for plan review shall be 25% of the amount to be charged for the construction permit." The Schedule an Inspection page says "Please do not leave inspection requests on voicemail, as they will not be honored," and "Under State Law, Contractors should not ask for final payment and final payment should not be made until a Certificate of Occupancy or Certificate of Approval is obtained."
