Roofing in West Milford 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, West Milford's Building Department codes page lists the "International Residential Code New Jersey Edition" as the one- and two-family dwelling subcode without naming an edition, and says the Rehabilitation Subchapter "regulates work on ALL existing buildings in the state."

No permit is needed under state law to reroof a detached one- or two-family house, and West Milford's Building Department FAQ says the same: "As of March 5, 2018 a roof permit is NOT required for the repair or replacement of a roof on DETACHED one and two family dwelling. All other buildings will require a permit." A townhouse, other attached dwelling or any other building needs a permit from the Building Department, 1480 Union Valley Road, 973-728-2780. Where a roof permit is required, the Township's construction fees (Code section 135-5 as amended by Ordinance 2026-004, adopted January 21, 2026 and effective February 10, 2026) set a flat fee of $100 for a residential roof in use groups R-3 and R-5 and, for all other use groups, $50 per $1,000 of estimated cost of work with a $100 minimum; the FAQ says "Roofing, siding, pools and sheds have a flat fee." For a property on the Township's Lake Community Master List, Code section 110-7 requires every applicant for a zoning, building or construction permit to give the property owners' association notice of the application by certified mail and submit the receipt; applications without it "will be deemed incomplete and will not be considered until such proof of notice has been provided." Inspections are scheduled by phone: "Call only when work is ready for inspections and give at least 24 hours notice prior to the time inspection is needed."
