Union Short-Term Rental Regulations: A 2026 Guide For Airbnb Hosts

Do you own a house in Union, New Jersey and you're weighing whether to put it on Airbnb or Vrbo? Well, the good news is that Union hasn't banned short-term rentals, which is more than several towns around it can say. The Township of Union, in Union County, licenses them instead, under an ordinance its Township Committee passed in the summer of 2023.

The catch is that the ordinance was written for homeowners rather than for investors. Chapter 447, Article IV of the Township Code only permits a short-term rental in a home you live in yourself, caps you at 15 separate rentals or 90 nights a year, whichever hits first, and charges $500 for a licence that runs twelve months. Rent out the pool or the yard on its own and you're already in breach, since the Committee banned that in October 2024.

So let's walk through what it actually takes to do this properly: who qualifies, what the licence costs in 2026, the two layers of tax on a booking, how fast the township can pull your licence, and who to call when your property doesn't fit. Every figure below comes from Union's own code or from New Jersey's Division of Taxation, checked in July 2026. Before you spend that $500, run the property through BNBCalc first, because 90 nights is a short season to earn it back.

What are Short-Term Rental (Airbnb, VRBO) Regulations in Union, New Jersey?

Ninety nights is the number that decides most of this, so it helps to see the whole shape of the rule before you budget around it.

Union defines a short-term rental as a dwelling unit where transient lodging is provided for compensation for stays of between one and 30 consecutive nights. The unit has to be one that would normally count as a residence rather than a hotel, motel or bed-and-breakfast. Anything longer than 30 nights falls outside Article IV entirely and becomes a normal tenancy question.

The gate everything else hangs on is owner-occupancy. Under § 447-45F, the person offering the unit must be the owner, and a tenant of a property may not apply. If the owner is a company or a trust, at least one principal or member has to live there.

"Live there" carries a definition with teeth, too. Your principal residence is the address where you spend the majority of your non-working time, no fewer than 150 days in a calendar year. It also has to be the clear centre of your domestic life, and the address printed on your driver's licence or state ID. All three tests apply, not just the convenient one.

Assuming you clear that, your property still has to sit in one of four categories:

• A unit in a condominium, homeowners or cooperative association, where the bylaws or master deed permit short-term rentals and where you legally identify an address inside that association as your principal residence.
• An owner-occupied single-family residence.
• A legally approved and permitted accessory dwelling unit, where you live in the primary residence on the lot.
• A two-family dwelling where both units are under common ownership and one of them is owner-occupied.

Several things are ruled out flatly. Non-habitable basements, attics and cellars can't be rented. Neither can illegally nonconforming properties, so your lot has to comply with zoning, hold a variance, or be certified by the Zoning Board as a preexisting nonconforming condition under N.J.S.A. 40:55D-68.

Multifamily buildings where rent is set by HUD, a State agency or a developer agreement are excluded as well. So are hotels, motels, rooming houses, dormitories, nursing homes, assisted living, senior housing, shelters, and housing owned by a school or run for religious or charitable purposes.

One amendment catches people out, because it's newer than most of the write-ups floating around. On 22 October 2024, Ordinance No. 5833 added a definition of "amenities" covering swimming pools, pool cabanas, hot tubs, decks, patios and yards, then banned renting any of them at any time. So the pool-by-the-hour listing, the cabana rental, the backyard party booking: none of those are permitted in Union, licence or no licence.

Don't forget to check that against anything you were told before autumn 2024.

There's also a zoning gate sitting above all of it. Article IV opens by saying short-term rentals are permitted only in districts where they're allowed as accessory uses, yet a search of the whole Township Code turns up no zoning provision that names short-term rentals anywhere. That makes the Zoning Officer's reading of your specific district the answer, so do check your address with the Building Department before you assume anything.

Starting a Short-Term Rental Business in Union

Unfortunately for most people reading this, that owner-occupancy rule is where the investment case quietly ends. You can't buy a second house in Union, furnish it, and run it as a nightly rental, because you don't live in it. You can't have a tenant run one for you either, since tenants are barred from applying at all. And an LLC doesn't solve it, because a principal of the LLC has to be sleeping there 150 nights a year anyway.

It's a homeowner's rule, not an investor's.

What's left is the spare-room or second-unit model. You live in the house, you rent the whole thing or a legal second unit inside it for stretches when you're away or when you have space, and you stop at 90 nights.

Work that ceiling through with real numbers, because it changes the shape of the business. A dwelling unit is limited to one short-term rental contract at a time, and you're permitted 15 separate rentals or 90 nights a year, whichever comes first.

Fifteen weekend bookings of two nights each burns all fifteen rentals while using only 30 of your nights. On a weekend-heavy calendar, the rental count binds long before the night count does. Longer stays use the allowance far better, since six two-week bookings spends six rentals and 84 nights.

Two more operating rules land on the marketing side. You aren't allowed to put up any sign or other marker identifying the property as a short-term rental, and your township licence number must appear in every print, digital and internet advertisement, plus any real estate listing.

Which means the listing you write on day one has to carry a number you don't have yet. That's the practical reason the ordinance treats advertising before licensing as an offence in itself.

If the numbers don't work at 90 nights, the honest alternatives are a 30-plus-night furnished rental, which sits outside Article IV altogether, or a different municipality. Our New Jersey statewide guide sets out how much this varies town by town, and the Union County guide covers the neighbouring municipalities where the rules are looser.

Short-Term Rental Licensing Requirement in Union

Assuming your home does qualify and you're able to live with the 90 nights, there's still the licence itself to get through, and it runs through one office rather than several.

The short-term rental licence comes from the Zoning Officer of Union Township, or a designee, and § 447-46A requires it before you rent or advertise any short-term rental. The initial registration fee is $500, and the ordinance is blunt that it's non-refundable, including where the application is denied. Renewal is annual, dated from the anniversary of your original issuance, at a $250 renewal registration fee.

Once you file a complete application with all documents and fees, the Zoning Officer has 30 days to either issue the licence or hand you a written denial stating the reasons, provided you give access to the property for any inspection. A granted licence is valid for one year.

Approval isn't a private matter, either. Notice of the decision gets mailed to you and to the adjoining property owners, so your neighbours find out you've been licensed. Any aggrieved party, which includes those neighbours, can appeal to the Zoning Board of Adjustment within 20 days under N.J.S.A. 40:55D-72, and the Board then has 30 days to affirm, reverse or modify. That Board meets Wednesdays at 7:30 p.m. in the Municipal Building, so an appeal is heard in public.

Two expiry rules are worth putting in your calendar now. A licence expires automatically when the property changes ownership, and the new owner starts over with a fresh initial application and the full $500. A new initial application is also required if your licence lapses for more than three months, or if it's revoked or suspended. Renewing a day late is fine; forgetting for a season costs you $250 extra.

Required Documents for Union Short-Term Rentals

Since that $500 doesn't come back, it's worth getting the paperwork right the first time. Section 447-46B lists six things every initial application has to carry:

• The Township's own short-term rental licence application form. It isn't published on the Township website, so you'll need to get it from the Zoning Officer at the Building Department counter.
• The $500 initial registration fee, non-refundable whatever the outcome.
• Proof of your current ownership of the unit.
• Proof of general liability insurance of at least $500,000. Standard homeowners policies routinely exclude paid guest stays, so make sure you ask your carrier for a short-term rental endorsement or a separate policy rather than assuming your existing declarations page satisfies this.
• Documentation that the property was inspected for compliance with the Township's fire code and Property Maintenance Code within the past six months. On renewal the window widens to three years, so only the first application forces a fresh inspection.
• Proof that all city taxes and water charges are paid to date. An outstanding sewer bill is enough to stall the file, so clear the Tax Collector's office before you file.

Two more items aren't application documents but have to exist before a guest arrives. Working smoke and carbon monoxide detectors must be installed in the locations the Township's adopted code requires, and a functional fire extinguisher has to be visibly installed in any kitchen area. Keep in mind that the fire inspection is what confirms both, which is why booking it early is the difference between a licence in 30 days and a licence in three months.

You'll also be posting a small pack of information in a prominent spot inside the unit, and preparing it alongside the application saves a second pass later. Five items go up:

• Your name, or the name of a principal if an entity owns the property, with an email address and phone number.
• The maximum number of parking spaces available to guests.
• The trash and recycling pick-up day, with the disposal rules that go with it.
• A copy of the Township nuisance ordinance in Chapter 735.
• Notice that guests and owners alike can be cited or fined for breaking any Township ordinance.

Union Short-Term Rental Taxes

Assuming you get through all that and are able to start hosting, there's still tax to deal with, though Union's stack is lighter than most New Jersey hosts expect.

Charge	Rate	Collected by
New Jersey Sales Tax	6.625%	NJ Division of Taxation (platform collects)
State Occupancy Fee	5%	NJ Division of Taxation (platform collects)
Municipal Occupancy Tax on short-term rentals	not imposed	not applicable in Union
Total on a taxable booking	11.625%	as of July 2026

That third row is the one that surprises people, so it deserves a moment. Union Township does impose a 3% municipal occupancy tax, effective 1 November 2003. The state's list of municipal rates, dated 14 May 2026, shows that rate applying to hotel and motel occupancies only.

Extending it to short-term rentals takes a separate ordinance. The Division of Taxation's list of municipalities that have adopted one, updated April 2026, contains no Union County municipality at all. So a Union host owes 11.625%, not the 14.625% payable a few towns over.

Union sits well outside the Meadowlands district too, so the 3% Meadowlands Regional Hotel Use Assessment doesn't apply. That one covers ten named Bergen County towns and four in Hudson County, per Technical Bulletin TB-81R2.

Whether you owe anything at all depends on how the booking was made. TB-81R2 charges Sales Tax and the State Occupancy Fee only where the stay comes through a transient space marketplace such as Airbnb or Vrbo, or where the unit is "professionally managed". A unit counts as professionally managed when the owner or controller offers two or more other New Jersey units for rent that year.

A Union homeowner renting their own single house directly, with no platform involved, therefore falls outside the tax entirely. Given the owner-occupancy rule, plenty of Union hosts land in exactly that position.

For everyone booking through a platform, Airbnb's New Jersey tax page confirms it collects and remits the 6.625% Sales Tax and the 5% State Occupancy Fee on reservations of 89 nights or shorter, so you don't handle either yourself. Where a unit is professionally managed and rented directly, the owner registers with the Division of Revenue and Enterprise Services on Form NJ-REG at least 15 business days before renting, then collects and remits.

Four exemptions sit in the statute and are worth knowing about:

• Stays of 90 consecutive days or more.
• Rentals executed entirely by a New Jersey licensed real estate broker, with keys handed over at the broker's office.
• Rentals to Form ST-5 exempt organisations.
• Rentals to the federal or state government.

Your income tax is a separate matter, and the Township has no role in it.

New Jersey Wide Short-Term Rental Rules

Those tax rules are state law, which is a useful reminder that almost nothing above the tax line comes from Trenton at all.

New Jersey doesn't preempt local short-term rental regulation. The Division of Local Government Services told municipalities as recently as Local Finance Notice 2026-09, issued 7 April 2026, that "rental of short-term transient accommodations is largely subject to municipal ordinance".

The one statute that speaks directly to licensing is enabling rather than restrictive. N.J.S.A. 40:52-1(n) authorises a municipality to license the rental of property for terms under 175 consecutive days, and leaves the fee to each town's own ordinance. Union used that authority in 2023, and nothing in state law required it to.

So there's no statewide short-term rental registry, no state licence, and no state cap on nights. What you get instead is every municipality writing its own rules, which is why a guide for one town tells you nothing reliable about the next one.

That's not a small caveat in this corner of the state, where neighbouring municipalities land on completely different answers. So check the ordinance for the specific address before you buy, never a statewide summary.

The state layer that does bite is the tax framework enacted by P.L. 2018, c.49 and narrowed by P.L. 2019, c.235, which is what limits Sales Tax and the State Occupancy Fee to marketplace bookings and professionally managed units. And if you're comparing Union against the northern part of the state, the Meadowlands assessment is the one extra layer to price in, which the Bergen County guide covers town by town.

Does Union Strictly Enforce STR Rules?

Enforcement here doesn't look like a patrol. It looks like your neighbours, which follows naturally from a rule that mails them a notice the moment you're licensed.

Nobody is driving around counting suitcases. They're waiting for the phone to ring.

The trigger throughout § 447-49 is the "substantiated complaint". Three or more of them and the Zoning Officer or the Business Administrator shall revoke your licence, with no discretion in the wording, and the property is then ineligible for a new permit for a full year.

A single substantiated complaint can do it too, where the officer decides the interests of the township justify immediate revocation. Two substantiated complaints about excessive guest vehicles are enough on their own to put the licence at risk, which tells you how the ordinance expects most trouble to start.

Suspension can arrive faster still. Where a civil or criminal complaint or a code violation involves a condition creating substantial risk of injury to life or property, the licence can be suspended pending substantiation. You get written notice of any revocation or suspension within 10 days, then 10 business days to appeal in writing to the Business Administrator, who has 30 days to decide.

The ordinance also closes the obvious loophole. Failing to obtain a licence before advertising is equivalent to operating without one, and it brings enforcement action, a summons and the full penalty schedule. A live Airbnb listing with no licence number in it is therefore evidence of a violation on its own, whether or not anybody has stayed.

The penalties themselves run on a ladder. A first violation draws a warning, a second draws a civil penalty, and a third costs you the approval with a one-year bar on reinstatement. Under § 447-49C(3), the fine runs from $100 to $2,000, alongside up to 90 days imprisonment or 90 days of community service, in any combination the Municipal Court judge chooses. Be aware that each successive day a violation continues is a separate offence, so a listing left up through a summer weekend isn't one $2,000 exposure, it's several.

Union doesn't publish how many licences it has issued or how many summonses it has written, and I couldn't find a count anywhere official, so treat the enforcement question as one of mechanism rather than of odds. The mechanism is complaint-driven, the paperwork trail is public, and the appeal route runs through a township official rather than a court.

How to Start a Short-Term Rental Business in Union

Given how much of that is decided before you ever take a booking, the order you work through it in matters more than it looks.

1. Confirm you're eligible before spending anything. You must own the property, live in it as your principal residence for at least 150 days a year, and fit one of the four permitted property categories. Tenants and absentee owners stop here.
2. Check the zoning with the Building Department. Article IV permits short-term rentals only where they're allowed as an accessory use, and no zoning provision in the code names them, so get the Zoning Officer's read on your district in writing.
3. Read your association documents if you're in a condo, co-op or HOA. The bylaws or master deed have to permit short-term rentals, and the township will expect that in your file.
4. Book the fire and property maintenance inspection early. Initial applications need documentation of an inspection within the past six months, and inspection calendars, not paperwork, are what usually set your start date.
5. Sort the insurance. You'll need proof of general liability cover of at least $500,000 written for paid guest stays.
6. Clear your taxes and water bill. Proof that all municipal charges are paid to date is an application requirement, not a formality.
7. File with the Zoning Officer and pay the $500. Expect a decision within 30 days of a complete file, and expect your adjoining neighbours to be told.
8. Set up the unit before your first guest: smoke and CO detectors, a visible kitchen fire extinguisher, and the posted pack of owner contact details, parking count, trash day, nuisance ordinance and fine notice.
9. Put your licence number in every listing, put up no signage at all, and start the occupant log: names, plus the start and end date of each stay, available to the Zoning Officer and the Police on request.
10. Run the calendar against the cap. Fifteen rentals or 90 nights, whichever lands first, one contract at a time, and no guest under 21 signing the agreement.
11. Diarise the renewal for the anniversary of issuance, at $250, with an inspection no older than three years.

Who to Contact in Union about Short-Term Rental Regulations and Zoning?

Whichever of those steps you get stuck on, four offices in the same building handle nearly all of it, and picking the right one first saves an afternoon.

What Do Airbnb Hosts in Union on Reddit and Bigger Pockets Think about Local Regulations?

Since the ordinance decides so much before a single guest books, host sentiment here is less about compliance and more about whether the model survives the cap. I should be straight about my sources, though. Reddit blocks automated access and its platform policy rules out the commercial data use we'd need, and I couldn't reach a single Union-specific BiggerPockets thread. So what follows is my read of the general pattern rather than a survey of anything.

The recurring complaint about New Jersey among investor-minded hosts is fragmentation, and Union is a clean illustration of it. Three neighbouring municipalities can run a ban, a 60-night cap and a 90-night cap, which makes any statewide rule of thumb useless and pushes people toward buying in whichever town they already understand.

The owner-occupancy requirement draws less anger than you'd expect, though, mostly because it's unambiguous. There's no grey zone to litigate and no structure that gets around it. People either qualify or they move on, which is a different experience from towns where the rules are vague enough to tempt a gamble.

What does generate friction is the combination of a neighbour-notified licence and a complaint-triggered revocation. A host who annoys two neighbours has a live problem, and no amount of paperwork insulates them from it. So if your driveway holds two cars and your guests routinely arrive with three, the vehicle-complaint clause is the one to worry about long before the fine schedule.

If you're weighing Union against the rest of the state before committing, the New Jersey market data is the faster way to see where 90 permitted nights can still clear a return and where it can't.

Frequently Asked Questions

Can you legally run an Airbnb in Union, New Jersey in 2026?

Yes, with real limits. The Township of Union licenses short-term rentals under Chapter 447, Article IV of its code, adopted in July 2023. You must own the home and occupy it as your principal residence for at least 150 days a year. The property must also be an owner-occupied single-family home, a qualifying association unit, a permitted accessory dwelling unit, or a two-family under common ownership with one unit owner-occupied. Tenants cannot apply.

How much does a Union, New Jersey short-term rental licence cost?

The initial registration fee is $500 and it is non-refundable, including where the application is denied. The licence runs one year from the date of issuance, and renewal costs $250 annually on that anniversary. A licence expires automatically when the property changes hands, so a buyer pays the full $500 again rather than taking over the seller's licence.

How many nights a year can you rent a short-term rental in Union?

Ninety nights, or 15 separate rentals, whichever comes first. Only one rental contract may run at a time. Because the rental count and the night count both apply, a calendar built on two-night weekends exhausts the 15-rental limit after only 30 nights, while longer bookings use the night allowance more efficiently.

What taxes apply to a short-term rental in Union, New Jersey?

New Jersey Sales Tax of 6.625% and the 5% State Occupancy Fee, for a combined 11.625%. Union has not extended its municipal occupancy tax to short-term rentals, and the Meadowlands assessment does not reach Union County. Those state taxes apply only where the booking comes through a marketplace such as Airbnb or Vrbo, or where the unit is professionally managed. Airbnb collects and remits both on stays of 89 nights or shorter.

What are the penalties for renting without a licence in Union?

Advertising a short-term rental before obtaining a licence counts as operating without one, and draws enforcement action and a summons. Fines run from $100 to $2,000 per offence, with the possibility of up to 90 days imprisonment or 90 days of community service at the Municipal Court judge's discretion. Every additional day a violation continues is a separate offence, and three substantiated complaints require the township to revoke a licence for a year.
