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 Division of Construction Code Inspection and Enforcement says it "is responsible for enforcing the state Uniform Construction Code (N.J.A.C. 5:23) and other pertinent Township Ordinances" and names no code edition of its own.

Parsippany-Troy Hills' Division of Construction Code Inspection and Enforcement is at 1001 Parsippany Boulevard, phone 973-263-4366, email [email protected], open Monday to Friday 9 a.m. to 5 p.m., with inspections Monday to Friday 9 a.m. to 3 p.m. Reroofing a detached one- or two-family house needs no permit under the state rule. Reroofing a townhouse or other attached dwelling, or any other building, needs a construction permit, as does roof work that reaches the structure; the Township's Construction Portal says "All structural or system changes require permits prior to work commencing and require inspections during and upon completion of the work." The portal searches the Township's permit records and takes inspection requests; when scheduling, "make sure you have your permit number AND Application ID / Control Number." For other help, the Division's page says "please call us at 973-263-4366."
