Roofing in Cinnaminson 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 220 of the Township Code establishes the enforcing agency, the "Cinnaminson Township Code Enforcement Agency." The construction office's page says "This office follows the requirements under the DCA and Cinnaminson codes" and refers applicants to the Department of Community Affairs' list of current adopted codes; it names no code edition of its own.

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 in Cinnaminson needs one from the Township construction office, 1621 Riverton Road, Cinnaminson, 856-829-6000 extension 5 (the Building Inspections line on the office's page). The office's own permit guide lists "Roof: Building (Commercial only)," while the Township's Code Enforcement and Zoning FAQ says a new roof needs a permit "under most circumstances" and advises calling the Construction Department at extension 2312. Where a roof permit is required, section 265-7 of the Township Code (amended April 21, 2014 by Ord. No. 2014-8) says "The subcode fee for a permit to replace roofing or siding on a residence shall follow the schedule in Subsection A(1)(b) above," which charges "Up to $50,000: $30 per $1,000," then $23 per $1,000 for the next $50,000 and $19 per $1,000 above $100,000. The office says "Municipal Construction Permits WILL NOT be issued without proof of registration from any contractor working on your home" and lists "roofing and siding" among home improvements. The permit must be posted on the site with a copy of the approved plans, and the page warns that "State law mandates that the Construction Official issue a fine to any person who performs work without a permit if the construction is of a nature which requires a permit." Building inspections are made Tuesday and Thursday, 8:00 am to 12:00 pm and 5:00 pm to 7:00 pm. The construction permit application and subcode technical sections are posted on the Township's page as PDF forms.
