Roofing in Old Tappan, 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, the Old Tappan Building & Zoning and Building Permit pages name no code edition.

No permit is needed under state law to reroof a detached one- or two-family house, and the Old Tappan Building Permit page lists "Re-Roofing" under "The following work does not need a Permit," adding "When in doubt, please call the Building Department." A townhouse, other attached dwelling or any other building needs a permit under the state rule from the Borough of Old Tappan Building Department, 227 Old Tappan Road, Old Tappan, NJ 07675, phone 201-664-1849 ext. 19. The page says "Permits must be obtained before the start of work." The Construction Official keeps walk-in hours ("No appointment necessary") on Monday from 12:00pm to 1:00pm, Tuesday from 9:00am to 10:00am, Thursday from 8:30am to 9:00am and Friday from 1:30pm to 2:00pm, and the Technical Assistant, who schedules inspections, works Monday through Friday from 9:00am to 4:00pm. Inspection requests are made by email from the Building & Zoning page, or by appointment at 201-664-1849 ext. 19. Where a roof permit is required, Section 100-3 of the Borough Code (last amended September 7, 2021 by Ord. No. 1190-21) prices "Renovations, alterations, repairs, minor work" at "Twenty-five dollars per $1,000 cost (or fraction thereof)" with a "Minimum fee: $65," and its fire protection fees include "Hot-tar kettle roof: $75." The same section says "The fee for not obtaining a Borough permit prior to the start of work shall be double the permit fee." The Building & Zoning page's forms list links "DCA Site - All Construction Permits"; the pages name no online permit portal.
