Roofing in Monroe Township (Middlesex County), 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 Monroe Township Construction Department's Required Inspections sheet says construction work "must be INSPECTED IN ACCORDANCE WITH THE STATE OF NJ UNIFORM CONSTRUCTION CODE REGULATIONS" and names no code edition.

No permit is needed under state law to reroof a detached one- or two-family house, and the Monroe Township Construction Department's own notice says roofing on one- and two-family dwellings no longer needs a construction permit. A townhouse, other attached dwelling or any other building needs a permit from the Construction Department, 732-656-4585, which the State's directory of construction offices lists on Perrineville Road (mailing address Jamesburg, NJ 08831); the department's notice gives its hours as Monday through Friday, 8:30 a.m. to 4:30 p.m., and its in-person address as 76 Gravel Hill Spotswood Road. Inspections are scheduled by phone between 8:30 a.m. and 2:30 p.m., and the owner or person in charge of the work "MUST NOTIFY THE CONSTRUCTION OFFICE WHEN WORK IS READY FOR ANY REQUIRED INSPECTION." The notice also says "all final inspections for building, electric, plumbing, fire protection and elevators must be completed before final payment is made to the contractor." A memo dated June 5, 2023 from the Township's Zoning Officer to all contractors gives the permitted hours of construction under the Municipal Code as 7:00 a.m. to 6:00 p.m. on weekdays and 8:00 a.m. to 5:00 p.m. on Saturdays, with no construction activity on Sundays, and warns of fines of up to $500.00 for each day.
