Union City's Building Department at City Hall, 3715 Palisade Avenue, enforces the Uniform Construction Code for the most densely populated city in New Jersey — a Hudson County city on the Palisades that is routinely confused with Union Township in Union County and shares nothing with it but a name. Chapter 122 of the city code carries a waiver found nowhere else: the city waives all building construction permit fees for improvements to buildings constructed after 2002 that currently use exterior ceramic tiles, alongside waivers for qualified New Jersey nonprofit corporations' construction and for improvements that make structures more accessible for disabled persons.
The city's other rules follow the building after the permit. Under the building requirements and maintenance article, owners of all occupied buildings submit an annual certification to the Health Department by June 30 that there is no visible mould and no pending tenant mould complaint; an owner whose illegal occupancy displaces tenants is responsible for their relocation costs under state law; and the Rent Leveling Board, at the same City Hall address, administers rent control over the city's rental stock.
This guide covers Union City in Hudson County. West New York, North Bergen, Weehawken and Hoboken are separate Hudson County municipalities with their own enforcing agencies, Hudson County issues no construction permits, and Union Township in Union County is a different municipality with a different code.
Ceramic tile is a fee waiver, not a violation. Chapter 122 says the city shall waive all building construction permit fees for any building constructed after 2002 currently utilising exterior ceramic tiles, to promote replacement of those facades. The waiver covers the city's fees, not the state training fee, and it applies to the improvement of the building — ask for it on the application rather than after the fee is paid.
What requires a building permit in Union City?
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, Union City 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
- Facade replacement on a post-2002 ceramic-tile building, which takes a permit like any other but with the city's fees waived on request
- Nonprofit construction and accessibility improvements, which take permits with the city's fees waived under Chapter 122
- Any renovation to a rent-controlled unit, which the Rent Leveling Board registers alongside the construction 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 Building 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. Union City'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 Chapter 122 fee waivers and the annual mould certification and rent control regimes that follow every occupied building.
Who handles permitting in Union City?
The Building Department is the enforcing agency, with the Construction Official and the building, electrical, plumbing and fire subcode officials reviewing their sections of the state UCC jacket at City Hall. The zoning officer signs off before the permit, the Planning Board and Zoning Board hear applications, the Health Department receives the annual mould certifications, and the Rent Leveling Board administers rent control from the same building.

Permit types
Residential permits
A Union City house project files the state UCC jacket with the subcode sections at City Hall, with zoning sign-off attached and the home improvement registration number on the application. A post-2002 building with a ceramic-tile facade files the same jacket and requests the Chapter 122 waiver of the city's fees; a rent-controlled building registers the renovation with the Rent Leveling Board; and every occupied building's owner files the mould certification with the Health Department by June 30 each year.
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 Union City licenses no trades of its own.
Commercial permits
Commercial and multi-family work in Union City clears site plan review, then files for construction review under Chapter 155's subcode fee schedule, amended most recently in 2024 and 2025. Nonprofit corporations building in the city and any project improving accessibility for disabled persons request the Chapter 122 waiver, and a change of use takes the certificate of occupancy or continued occupancy priced under the fee chapter.
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 Union City the Palisades bring steep-slope and retaining-wall questions to nearly every site, the North Hudson Sewerage Authority signs off on connections, and the Hudson County planning board reviews frontage on county roads. 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.
Union City permit costs and fees
Fees follow Chapter 155 of the Union City code — the building, electrical, plumbing and fire subcode fees and the certificate fees it lists — plus the state training fee, with the Chapter 122 waivers applied on request.
| Item | Fee or rule |
|---|---|
| Construction permit | Sum of the subcode fees under Chapter 155, amended in 2024 and 2025, paid before issuance |
| Ceramic-tile facades | City permit fees waived for improvements to post-2002 buildings with exterior ceramic tile |
| Nonprofits and accessibility | City permit fees waived for qualified nonprofit construction and accessibility improvements |
| Certificates | Certificate of occupancy and continued occupancy fees under Chapter 155 |
| Rent control | Rent Leveling Board registration and any capital improvement surcharge application |
| State training fee | Added to every permit under N.J.A.C. 5:23-4.19 — not waived |
June 30 is a construction deadline too. Every owner of an occupied building in Union City files an annual certification with the Health Department, no later than June 30, that there is no visible mould and no pending tenant mould complaint. A renovation that opens walls in the spring is the moment to fix what the certification will have to swear to.
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
- Rent-controlled units — Rent Leveling Board registration alongside the construction permit
- 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 Union City 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
Union City reviews on the state's twenty-business-day clock at a busy counter. What delays a Union City file is a waiver requested after the fee is paid, a rent-controlled renovation the Rent Leveling Board has not seen, and the wrong municipality — applications and calls meant for Union Township in Union County arrive here every week.
Inspections in Union City
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. Union City inspects by subcode from the Building Department at City Hall, with certificates of occupancy and continued occupancy priced under Chapter 155; the Health Department's mould certification and the Rent Leveling Board's registrations run on their own calendars beside the construction file.
