New Brunswick's Construction Department on the second floor of 25 Kirkpatrick Street enforces the Uniform Construction Code for the Middlesex County seat — the city around Rutgers, Johnson and Johnson and the Robert Wood Johnson campus, not the townships of North Brunswick or East Brunswick that share its name and its county. Its filing rules are its own: four copies of the state's uniform permit application are required per permit, a contact information sheet is filled out in addition to the application, and the continuing certificate of occupancy form is a separate document that is not part of the permit application.
Inspections in New Brunswick are scheduled between 9:30 am and 3:30 pm, and a representative over eighteen years of age must be present at the location when the inspection is conducted — an inspector who finds no adult leaves. Much of the city's construction runs through redevelopment plans administered with the New Brunswick Development Corporation and the Parking Authority, and the Division of Housing Inspections in the same building runs the city's rental and housing inspection programme.
This guide covers the City of New Brunswick. North Brunswick, East Brunswick, Highland Park, Piscataway and Franklin Township are separate municipalities with their own enforcing agencies, and Middlesex County issues no construction permits.
Four copies, one sheet, one adult. The department's instructions are exact: four copies of the uniform permit application are required per permit, a contact information sheet is completed in addition to the application, and an inspection is conducted only when a representative over eighteen years of age is present at the location between 9:30 am and 3:30 pm. A file short a copy or a site without an adult does not move.
What requires a building permit in New Brunswick?
New Jersey runs on a single statewide instrument, the Uniform Construction Code (N.J.A.C. 5:23), in force since January 1977 and administered by the Department of Community Affairs. Rather than writing its own code, the state adopts the national model codes as subcodes with New Jersey amendments: the International Building Code (building subcode), the International Residential Code for one- and two-family dwellings, the National Standard Plumbing Code — not the International Plumbing Code used in neighbouring states — the National Electrical Code, and the mechanical, fuel gas and energy codes. The 2024 editions of the I-codes and the NSPC, with the 2023 NEC, took effect on August 17, 2026 and replace the 2021 editions and the 2020 NEC; the usual six-month grace period lets an applicant file under either edition until roughly mid-February 2027. Under N.J.S.A. 52:27D-119 et seq. no municipality, New Brunswick included, may adopt different technical standards — what is local is the enforcing agency, the fee ordinance, the zoning approvals that precede the permit, and the certificates that follow it.
The UCC itself draws the exemption line. Ordinary maintenance under N.J.A.C. 5:23-2.7 needs no permit, no notice and no inspection; minor work under 5:23-2.17A needs a permit but may begin once the enforcing agency has been notified, with the application filed and inspected afterwards. Everything else waits for the issued permit.
Typically permit required
- Every construction permit, filed in four copies with the contact information sheet at 25 Kirkpatrick Street
- Work in a redevelopment area, where the adopted plan governs use and bulk and the Planning Board application precedes the permit
- Any continuing certificate of occupancy, applied for on its own form rather than with the permit
- New buildings, additions and any structural work on an existing building
- Interior alterations that reconfigure space, add plumbing fixtures or extend circuits — renovation, alteration and reconstruction under the rehabilitation subcode
- Decks, and sheds over 200 square feet, over ten feet tall or with any utility connection
Often exempt
- Ordinary maintenance under N.J.A.C. 5:23-2.7, which the department does not need to hear about
- Painting, wallpapering and interior finishes on less than a quarter of the wall area of a house
- Like-for-like replacement of windows and doors in the same opening, and glass in any window or door
- Roofing and siding replacement on a one- or two-family dwelling
- Garden sheds up to 200 square feet and ten feet high with no utilities, and fences up to six feet — the zoning permit still applies to both
What is actually local, and what is not
Technical standards are the state's. New Brunswick's layer is the local enforcing agency — the construction official and the building, electrical, plumbing and fire subcode officials, each licensed by the state under N.J.A.C. 5:23-5 — plus the municipal fee ordinance, the zoning officer's sign-off, and the four-copy filing rule, the contact sheet and the inspection window the Construction Department publishes.
Who handles permitting in New Brunswick?
The Construction Department is the enforcing agency, with the Construction Official — who also serves as a fire inspector — and the building, electrical, plumbing and fire subcode officials reviewing their sections of the state UCC jacket; the Division of Housing Inspections shares the building. The zoning officer signs off before the permit, the Planning Board and Zoning Board hear applications, and the city's redevelopment plans govern much of downtown and the hospital and university districts.

Permit types
Residential permits
A New Brunswick house project takes zoning sign-off, then files four copies of the state UCC jacket and subcode sections with the contact information sheet at Kirkpatrick Street, with the home improvement registration number on the application. Inspections are booked into the 9:30 to 3:30 window with an adult on site, and a house that changes hands or tenants takes the continuing certificate of occupancy on its own form.
How New Jersey contractor credentials work
New Jersey has no state general contractor license. What it has instead is a registration that doubles as a permit gate: a home improvement contractor business must be registered with the Division of Consumer Affairs under the Contractors' Registration Act (N.J.S.A. 56:8-136 et seq.), and N.J.A.C. 5:23-2.15(b)8 requires the registration number on the construction permit application — an enforcing agency may not issue a home improvement permit to an unregistered contractor. Registration now carries commercial general liability insurance of at least five hundred thousand dollars per occurrence, workers' compensation cover and a tiered compliance bond, and the 2024 Home Improvement and Home Elevation Contractor Licensing Act is phasing in individual licensing through a new state board. New construction is different: a new-home builder registers with the Department of Community Affairs under the New Home Warranty and Builders' Registration Act and shows the builder registration card at permit. Electrical contractors, master plumbers and HVACR contractors hold separate state licenses from Consumer Affairs boards. Owners working on their own home are exempt from registration, and New Brunswick licenses no trades of its own.
Commercial permits
Commercial and institutional work in New Brunswick very often runs under a redevelopment plan, with the Planning Board application preceding the permit; construction review follows on four copies with the contact sheet, and a change of use takes the continuing certificate of occupancy filed separately. The university's and hospitals' projects follow the same enforcing agency unless the state has retained them.
Prior approvals, subcode review and the twenty-day clock
A New Jersey construction permit is one application with technical sections — the state's UCC F100 jacket with building, electrical, plumbing, fire and mechanical subcode forms — and each subcode official reviews their own section. The permit cannot issue until the prior approvals are in hand: zoning or planning board approval under the Municipal Land Use Law is a separate track that precedes the construction permit, and where a project touches a county road or county drainage the county planning board signs off as well. Sites disturbing 5,000 square feet or more need soil erosion certification from the regional soil conservation district, and DEP approvals apply in flood hazard, wetland and coastal areas. In New Brunswick the Raritan River waterfront brings DEP flood hazard approvals into the file, the Middlesex County Utilities Authority signs off on sewer connections, and redevelopment plans replace base zoning across much of downtown. Once complete, N.J.A.C. 5:23-2.16 gives the enforcing agency twenty business days to approve or reject a complete application, with a written list of deficiencies on any rejection.
New Brunswick permit costs and fees
Fees follow the city's construction code chapter — the sum of the subcode fees plus the state training fee — collected by the Construction Department before issuance.
| Item | Fee or rule |
|---|---|
| Construction permit | Sum of the subcode fees under the city's construction code chapter, paid before issuance |
| Filing | Four copies of the application per permit, with the contact information sheet |
| Continuing certificate of occupancy | Separate application and inspection on a change of ownership or tenancy |
| Certificate of occupancy | After all subcode finals, inspected within the 9:30 to 3:30 window |
| Land use applications | Planning Board and Zoning Board fees and escrows |
| State training fee | Added to every permit under N.J.A.C. 5:23-4.19 |
The inspection window is six hours. New Brunswick schedules inspections between 9:30 am and 3:30 pm, and requires a representative over eighteen years of age at the location. A contractor who leaves a site unattended in the window loses the slot, and a re-inspection is a new request.
Trade permits and who may pull them
Trade work is permitted through the same application under the electrical, plumbing, fire and mechanical subcode sections, and inspected by the subcode official for each.
Permit required
- Continuing certificates — own form, separate from the permit application
- Electrical — state-licensed electrical contractor; electrical subcode section
- Plumbing and gas piping — state-licensed master plumber; plumbing subcode section under the NSPC
- HVAC and fuel-fired equipment — licensed HVACR contractor; mechanical or fire subcode section
- Fire protection, alarms and sprinklers — fire subcode section, with fire official review
Typically exempt
- Like-for-like fixture, receptacle, switch and light fixture replacement in the same location
- Communications and low-voltage wiring in a house that does not penetrate a fire-rated assembly
How to apply for a New Brunswick building permit
A zoning permit or planning board approval under the Municipal Land Use Law precedes the construction permit.
The home improvement registration number, or the new-home builder registration card, goes on the application.
One F100 application with the building, electrical, plumbing, fire and mechanical sections the scope requires, plus sealed plans where the UCC demands them.
Soil conservation, county planning board, DEP or overlay agency sign-offs are attached before the permit can issue.
Fees follow the local ordinance plus the state training fee surcharge, and are due before issuance.
Footing to final under 5:23-2.18, then the certificate of occupancy or approval that closes the permit.
Review, corrections and what actually causes delay
New Brunswick reviews on the state's twenty-business-day clock from a complete four-copy filing. What delays a file here is an application in fewer than four copies, a missing contact sheet, and a site with no adult when the inspector arrives.
Inspections in New Brunswick
N.J.A.C. 5:23-2.18 sets the inspection sequence statewide — bottom of footing trenches, foundation and backfill, rough framing, electrical and plumbing, insulation, and final — and the enforcing agency must inspect within three business days of the request. Work that passes final receives a certificate of occupancy for new buildings or changes of use, or a certificate of approval for everything else. New Brunswick inspects by subcode from the Construction Department between 9:30 am and 3:30 pm with an adult representative present; the continuing certificate of occupancy is inspected on its own application.
