Roofing in Allendale, 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 100 of the Allendale Borough Code, Section 100-1, establishes the "State Uniform Construction Code Enforcing Agency of the Borough of Allendale," and the Construction Code Office's "Do I Need a Permit?" page says "The State of New Jersey establishes the rules for when construction permits are required (NJAC 5:23-2.14 Construction permits-when required)."

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 Allendale needs one from the Borough's Construction Code Office. The office's "Do I Need a Permit?" page lists "Roofs" under "Permits are not required for the following (single or two family)," but the same page also says "Minor work is a category of listed work for one and two family residential structures such as roofing, siding and water heater replacements that require a construction permit; however, the work may proceed after formal notification is made to the Borough." This record does not decide which statement the office applies to a given job; a roofer who is unsure can call the office at 201-818-4400, ext. 202. Where a roof permit is required, the Borough's fee ordinance, Section 100-3A(2)(b), prices it with "Renovations, alterations, decks, roofing, siding and repairs": "The fee shall be $25 per $1,000 of the estimated cost, with a minimum fee of $75." Section 100-3A(1)(b) charges no plan review fee for roofing and siding on detached one- or two-family houses and applies the same cost-based fee "For all other use groups." Under the Borough Code, "The public shall have the right to do business with the Enforcing Agency at one central permit office located in the Municipal Building." The Construction Code Office is open "Monday through Friday between 9:00am and 4:30pm." Inspections are scheduled through the Borough's GovPilot portal, building inspections run "Mon - Thurs: 9am - 12:30pm," and the office asks for "a week lead time for inspections." The Borough's permits and forms page says "Payment for most permits can be made conveniently online through the Pay Now button at the bottom of the selected form."
