Roofing in Millburn 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, the Millburn Building Department page says the department enforces "the Uniform Construction Code of the State of New Jersey" and names no code edition, and its permitting FAQ says permits are required "in strict accordance with the requirements of the State of New Jersey Uniform Construction Code, N.J.A.C. 5:23"; Chapter 9 of the Township Code names no edition either.

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 needs one from the Millburn Building Department, 973-564-7055, which lists its physical address as 22 East Willow Street, the Township's temporary location (the department's page also still describes its office as on the first floor of Town Hall at 375 Millburn Avenue). It is open "Monday through Friday from 8:30 a.m. to 3:30 p.m." Where a roof permit is required, Millburn's fee ordinance, Township Code Section 9-1.5, lists among its miscellaneous building fees "(f) Siding/roofing: $10 per $1,000 estimated costs, provided the minimum fee shall be $65," and "The fee for plan review shall be 20% of the amount to be charged for the construction permit." Permit fees "can be paid by check or exact cash at Town Hall, or through mail," and "Any permit that is not paid for and picked up within 6 months of application will be voided." The department's FAQ says that for working without a permit "A penalty of $2,000 is assessed" and "Any work completed may require removal." It also says "Zoning approvals are required for all exterior building and site improvements and for all changes in use or tenancy of any rental space, building, or property," and that work in the Historic District may need Historic Preservation Commission approval. Inspections are requested in writing through the Township's SDL Portal or on the Construction Permit Inspection Request Form.
