Roofing in Frelinghuysen 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. Locally, Chapter 8 of the Township Code, read on October 3, 2026, establishes "a State Uniform Construction Code enforcing agency to be known as the Frelinghuysen Building Department" and sets its fees; it adopts no building code and names no code edition.

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 Frelinghuysen Building Department, which the State's municipal roster lists at 210 Route 661, PO Box 417, Johnsonburg, NJ 07846, phone 908-852-4121. Where a roof permit is required, section 8-1.7 of the Township Code, amended through Ord. No. 2025-03, prices "Renovations, alterations, repair and minor work" at "Estimated cost: $36 per $1,000," charges plan review at "20% of the construction permit fee," and says "There shall be a minimum fee of $75.00 on all permits, which does not include State Fees." The same section also states a "Minimum fee for construction permit, in part or in total" of $46.00, so confirm the current fee with the office. The roster lists the same construction official for Vernon Township; Frelinghuysen keeps its own office. The Township's own construction office web page could not be read when this record was prepared (it returned a bot challenge); call the office to confirm hours and forms before applying.
