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 Township's Building Division says it "is responsible for assuring compliance with the New Jersey Uniform Construction Code" and names no code edition of its own.

Piscataway Township's Building Division works from the Public Works building at 505 Sidney Road, phone 732-562-2325, Monday to Friday 8:30 a.m. to 4:30 p.m.; the page notes "we are closed from 12:20 - 1:30 p.m. daily for lunch." Its FAQ treats reroofing a detached one- or two-family house as ordinary repair work, listing "Roofing - The repair or replacement of existing roof covering on detached one- and two-family dwellings," and says "Permits, notifications, and inspections are not required for ordinary repair work." Reroofing a townhouse or other attached dwelling, or any other building, needs a construction permit. The FAQ says permits are charged "in accordance with the construction code fee schedule, which can be found in the Township Code - Chapter 14, Section 1.3," and that where no prior approvals are needed "a minimum of 20 business days should be planned for processing applications." Where a roof permit is required, that section, Township Code Section 14-1.3 as last amended in 2022, sets building subcode fees of $20 per $1,000 of cost, minimum $75, for "Roofing (nonresidential)" and a flat $75 for "Roofing and siding (residential)." The FAQ says: "A penalty of $2,000 is assessed and any work done may be required to be removed." Inspections of permitted work are requested through the SDL Portal or by emailing a written inspection form to [email protected], and "Inspections are conducted Monday through Friday from 9:45 AM - 3:15 PM."
