Suffolk County, New York Short-Term Rental Regulations: A 2026 Guide For Airbnb Hosts

Do you own a place in Suffolk County, New York and you're weighing whether to put it on Airbnb or Vrbo? Well, the good news is that the county has no rule of its own against renting your house out, and it isn't the government that decides your case anyway. The less welcome news is that the ten towns Suffolk is divided into mostly do say no, and several of the incorporated villages sitting inside those towns go further still.

That refusal is rarely written as the word "ban", which is why it catches people. Riverhead's code prohibits any rental of 29 days or less, Brookhaven won't issue a rental registration for a transient occupancy at all, and the Town of Islip makes you swear on the application form that your house won't be used as one. Out on the East End the shortest legal stay is two weeks. Only two governments in the whole county will sell you a permit for a genuinely short stay: the Town of Huntington, if you live in the house and stop at 90 nights a year, and Shelter Island, which licenses stays of 14 days or less for $150. Suffolk County, meanwhile, wants its 5.5% occupancy tax on every paid night under 30, whether or not your town would ever have let you rent.

So let's walk through what all that means for one specific address: which town you're in and what it allows, what a permit costs and how long it lasts, the two layers of tax you'll be collecting, how hard any of it gets enforced now that the towns have bought software, and who to call when something doesn't add up. Every figure below comes from a town's own code or application form, or from Suffolk County's and New York State's own pages, read in July 2026, and where I couldn't confirm something I've said so rather than filling the gap with a guess. Before you spend a dollar on furniture, run the property through BNBCalc first.

What are Short-Term Rental (Airbnb, VRBO) Regulations in Suffolk County, New York?

The county wanting its tax while your town forbids the rental sounds like a contradiction, so it's worth untangling the three governments that have a say here, because they're answering different questions.

New York State sets the floor, and it's a low one. A New York Department of State training deck for local governments puts it plainly: it is "up to each municipality to define, prohibit and/or regulate short term rentals as they choose". There's no state preemption to appeal to, so a town that wants nightly rentals gone can have them gone.

Suffolk County sits in the middle, and it collects rather than regulates. The Comptroller's own hotel/motel tax page puts the county occupancy tax at 5.5% of the per-diem rental rate, effective June 1, 2023, under Chapter 523, Article II of the county code. Then it adds the line that catches homeowners out, which is that the law "applies to all lodging facilities including residences and tourist homes, not just traditional hotels and motels." Beyond that tax, though, I found no county ordinance saying where or whether a short-term rental may operate. That's the piece people expect a county to handle, and Suffolk doesn't.

Your town writes the rule that decides everything. One more thing worth clearing up before the table: readers arriving from New York City coverage often assume the state's famous thirty-day rule travels with them. It doesn't, at least not by itself, since Multiple Dwelling Law § 3 says the chapter "shall apply to all cities with a population of three hundred twenty-five thousand or more" and leaves other municipalities to adopt it if they want it. Suffolk County contains no city at all, so the town code is the document that matters.

Town	Shortest legal paid stay	Where it's written
Babylon	No transient rule found; a permit is required for any home the owner doesn't live in, and it goes to a public hearing	Ch. 153, Art. I
Brookhaven	28 nights in the code, 30 nights on the town's own form	Rental License Application
East Hampton	Two weeks, and no more than twice in six months	Ch. 255 § 255-1-20
Huntington	Under 30 days is allowed with a permit, owner living there, 90 days a year	Rental Permits
Islip	Transient rentals prohibited; no night count published	Rental Occupancy Permits Application
Riverhead	30 nights, since 29 or fewer is transient	Rental Law Summarized
Shelter Island	14 days or less, under a license	Property Rentals
Smithtown	Not confirmed; a rental registry exists	Rental Property Registration Program
Southampton	15 nights, since 14 days or less is transient and prohibited	Ch. 270 §§ 270-1, 270-9C
Southold	14 nights, reported	East End Beacon, below

A few of those rows deserve their own sentence, because the mechanism differs. Southampton's code defines TRANSIENT as "a rental period of 14 days or less" and then says a transient rental is prohibited, which puts the first lawful booking at 15 nights rather than 14. East Hampton doesn't ban anything by name; instead its zoning says a single-family residence rented "for a term of not more than two weeks, on three or more occasions during any six-month period, shall be deemed to be unlawfully operating as a 'motel'", so two short lets a season are tolerated and the third one converts your house into an illegal hotel. Southold's 14-night minimum I could only source to the East End Beacon's report of the August 2023 vote, because the town's code chapter wouldn't render for me, so treat that number as reported rather than read.

Then there are the villages, and this is where a lot of owners get caught, since a village writes its own code and the town's rules stop at the village line. The Village of Babylon shows how blunt that gets, since § 281-4 says flatly that "no rental permit shall be issued to a transient rental property", defines that as any non-owner-occupied dwelling rented for less than 30 nights, and then adds that offering the unit "on a short-term rental website, including Airbnb, Home Away, VRBO and the like" creates a rebuttable presumption you're running one. Keep in mind that a mailing address tells you nothing about which code applies, so check whether your parcel sits inside an incorporated village before you read a single word of the town code.

Starting a Short-Term Rental Business in Suffolk County

Given how the village line can flip the answer on the same street, the honest question isn't whether short-term renting exists in Suffolk County but where it survives. Unfortunately for most people reading this, the thing you're probably picturing, a furnished house let by the weekend at nightly rates, is off the table across most of the county, and no permit, LLC or management company unlocks it. There's no workaround.

What's left are four different businesses, and they're not variations on one idea.

• The East End seasonal lease. In Southampton, East Hampton and Southold the market runs on two-week, monthly and full-season lets, which is what those minimums were designed to protect. The revenue per booking is large and the turnover is tiny, so it behaves more like landlording than hosting.
• Huntington's owner-occupied room. The town's short-term rental permit covers a room or rooms inside a one- or two-family home you live in, capped at no more than two bedrooms, stays under 30 consecutive days and no more than 90 days per calendar year. That's a spare-room income, not an investment thesis.
• Shelter Island's licensed vacation rental. The town licenses stays of 14 days or less for $150 and registers longer ones for free, which makes it the one place in Suffolk County where a whole-house short stay is squarely legal.
• The thirty-plus-night furnished rental. Anywhere in the county, a stay long enough to clear the local transient definition falls outside these rules and under ordinary landlord and tenant law, though you'll still need the town's rental permit.

Assuming none of those four fits your property, you're still better off knowing that now than after closing. The Nassau County guide covers the western half of Long Island, where the pattern is much the same and the towns are, if anything, blunter about it.

Short-Term Rental Licensing Requirements in Suffolk County

Whichever of those four routes matches your address, you'll be applying for two separate things rather than one: a permit from your town, which decides whether you may rent at all, and a Certificate of Authority from the county, which only lets you collect tax. Neither substitutes for the other, and the county's own portal says as much.

Town	Permit	Cost	Term
Babylon	Rental permit, after a public hearing	$400 first unit, $50 each additional	2 years
Brookhaven	Provisional House Rental License	$500 for 1 to 5 bedrooms, $500 per extra bedroom	15 months
East Hampton	Rental registry number	$200	2 years
Huntington	Short-term rental permit	$50 new, $25 renewal	1 year
Islip	Rental occupancy permit	$500 one-family, $1,000 two-family	2 years
Riverhead	Rental permit	$300	2 years
Shelter Island	Vacation rental license	$150	Expires 12/31/2027
Southampton	Rental permit	$400 standard on the 2026 schedule	2 years
Southold	Rental permit	$300	2 years

Smithtown is the gap in that table. Its rental property registration program exists and runs through an online portal, but the town publishes no fee, term or minimum stay on the page, and its code chapter wouldn't open for me, so I'd rather leave the row blank than print a number I haven't read.

Southampton's schedule is worth a closer look, because it prices behavior rather than paperwork. The 2026 fee schedule drops to $175 for veterans, seniors and volunteer fire or ambulance workers, waives the fee entirely for income-qualified tenants, and then charges $800 where the property is already in violation of Chapter 270. Apply after you've been caught and the permit costs twice what it would've cost you in January. Every fee here is as of July 2026, and towns reset them by resolution, so do check the current schedule before you write the check.

The county side is quicker and stricter about timing. Under the Comptroller's rules, every lodging facility has to register within 10 days of its first lodging rental, the Certificate of Authority that comes back must be displayed prominently where guests can see it, and it's non-assignable, so it dies with a sale of the property. Miss the registration and the fine is $50 for each day the facility goes unregistered, which is the sort of penalty that compounds while you're not thinking about it. That clock never stops.

These days, registration runs through Suffolk County's short-term rental portal. It calls itself "one central location for your registration and tax payment", though a banner warned when I checked in July 2026 that the filing and payment side was down, and that quarterly returns had to go in on the paper form.

Required Documents for Suffolk County Short-Term Rentals

Registering with the county asks for little more than your name and address, so the paperwork that takes real time is the town's. What each town wants varies, though the shape repeats across all ten of them.

• A notarized application signed by the owner. Agents and management companies generally can't sign for you. Brookhaven goes furthest here, requiring four separate notarized affidavits covering the rental, rooming house, residential and transient questions, and its short-form disclosures end the application outright with an "If Yes, STOP" if you answer either one the wrong way.
• Proof the house is legally what you say it is. A current certificate of occupancy or compliance, a property survey and floor plans for each unit are standard, and Babylon asks for all three plus the recorded deed.
• An inspection, or a licensed professional's certificate instead of one. Huntington schedules a town inspection or takes a licensed professional's report; Shelter Island requires written certification from a licensed architect, engineer or home inspector that the unit complies with the Property Maintenance Code; East Hampton makes the owner work through a self-inspection checklist covering smoke alarms, egress and bedroom sizes.
• A sworn statement about the use. Islip's application has you affirm "that the rental dwelling unit(s) are not to be occupied as a transient rental property, as is defined and prohibited within Town of Islip Code, Chapter 68, Article L". Signing that and then listing the place nightly isn't a code violation, it's a false sworn statement, which is a different order of problem.
• Notice to the neighbors, in Babylon. A 200-foot radius mailing and a posted sign are part of the application, and every new permit goes to a public hearing before the Rental Permit Review Board.
• A local contact. Most towns want a name and number for someone who can be reached about the property, and Brookhaven wants that person within 25 miles.

Do check the certificate of occupancy against reality before you file anything. A finished basement, a converted garage or a bedroom that was never on the plans will surface during the inspection, and at that point you've paid a non-refundable fee to tell the town about an unpermitted conversion.

Suffolk County Short-Term Rental Taxes

Assuming you get through all that and are able to start renting, there's still tax to deal with, and Suffolk hosts sit under two separate collectors who use two different definitions of a long stay.

Charge	Rate	Collected by
Hotel and motel occupancy tax	5.5% of the per-diem rate	Suffolk County Comptroller
New York State sales tax	4%	NYS Dept. of Taxation and Finance
Suffolk County local sales tax	4⅜%	NYS Dept. of Taxation and Finance
MCTD surcharge	⅜%	NYS Dept. of Taxation and Finance

The bottom three add up to a combined sales tax of 8¾%, which Publication 718 confirms against reporting code 4711. That combined figure moved recently, mind you: notice ST-25-1 raised Suffolk's local piece from 4¼% to 4⅜% on March 1, 2025, taking the total from 8⅝% up to 8¾%. Stack the county's occupancy tax on top and a guest is paying 14.25% over the nightly rate, and no town or village lodging tax turned up anywhere in my search to add to it.

That sales tax layer is newer than most hosts realize, since the state's own publication says that sales tax reaches short-term rental unit occupancy from March 1, 2025 wherever the rate is more than $2.00 per unit per day, and it makes booking services register as vendors and collect on everything they facilitate. So where a platform handles all of your bookings and gives you Form ST-155, you're off the hook for collecting it yourself. Get that form and keep it, though, because the relief hangs on the paperwork rather than on the platform's habits.

The occupancy tax works differently, and this is where hosts get tripped. Airbnb's own New York tax page says it collects the Suffolk "Hotel and Motel Occupancy Tax: 5.5% of the listing price including any cleaning fees, for reservations up to 29 nights", so a platform-only calendar is largely handled. Take a direct booking, though, or use a platform without that agreement, and the 5.5% is yours to collect and hand over. You file quarterly, for the periods ending the 20th of March, June, September and December. File late and the county adds a 10% penalty plus 1% a month, and if you willfully don't collect or pay the tax at all, that's a misdemeanor carrying up to $1,000 and a year.

Watch out for the two different long-stay thresholds, since they don't line up and people assume they do. A guest becomes a "permanent resident" exempt from the county's occupancy tax at 30 consecutive days, and the Comptroller says the first 30 days' tax then has to be refunded to them and taken as a credit on your next return. For state sales tax the same guest isn't exempt until 90 consecutive days. A 45-night booking is therefore free of occupancy tax and still fully taxable for sales tax. Two clocks, two answers.

New York State Short-Term Rental Rules Affecting Suffolk County Hosts

That collection duty landed on the platforms because Albany put it there, and it wasn't the only thing the state changed. Chapter 672 of 2024 and Chapter 99 of 2025 built a registration framework in Real Property Law Article 12-D, and it works from the county up rather than from the state down.

Section 447-c requires every covered county to run a short-term rental registration system unless it opted out by local law, with registrations valid two years, fees set locally to cover the registry's costs, and a power to revoke after three violations in two consecutive calendar years. The opt-out window closed around June 25, 2026, so Suffolk's decision is settled in law. Whether it opted in or out, I couldn't confirm: the county's own site and the legislature's document center both refuse automated access, the county code isn't archived anywhere I could reach, and no state body publishes a county-by-county list. The county's short-term rental portal does invite you to "register and update your Short Term Rental property", though nothing on it identifies itself as the Article 12-D registry rather than the occupancy-tax registration the Comptroller has run for years. Be aware that the answer may simply be a phone call away, and the number is in the contacts section below.

For most Suffolk hosts the answer changes less than you'd think, because § 447-b protects what already exists. Subdivision 6 protects any registry a county, city, town or village was already running when the article took effect, and that covers East Hampton, Southampton, Shelter Island and every other town program in this guide. Subdivision 7 blocks a town or village inside a covered county from starting a new registry, so the towns that don't have one probably won't be getting one.

The same section sets a baseline that's worth adopting whatever your county's status turns out to be:

• a conspicuously posted evacuation diagram identifying all means of egress from the unit
• a posted list of emergency numbers for police, fire and poison control
• a working fire extinguisher
• third-party liability cover of at least $300,000
• two years of guest records, including dates, guest counts and what each stay cost

Subdivision 5 suspends those duties until the applicable county registry exists, so they may not bind you today. Remember that your insurer doesn't care about that distinction: a standard homeowner's policy generally excludes paying guests, and $300,000 of third-party cover is a reasonable floor whether or not New York State is currently enforcing it. For how the rest of the state handles all this, our New York statewide guide maps the pattern, and the Westchester County guide covers the other big suburban county where town-level rules do the real work.

Does Suffolk County Strictly Enforce Short-Term Rental Rules?

State duties may be on hold, then, but nothing local is. Enforcement in Suffolk County comes from two directions at once, and the county's half is the more aggressive of the two.

Comptroller John M. Kennedy, Jr. has said in writing to the real estate industry that "there is substantial non-compliance with this law which has caused me to commence an initiative to vigorously pursue scofflaws", and the notice asks brokers and agents to tell their clients about the tax before a rental is arranged. The lever there is the $50-a-day non-registration fine rather than the tax itself, and it accrues from your first paid night, not from the day somebody notices.

On the town side, the change that matters arrived in 2026. The East Hampton Press reported in May 2026 that East Hampton Town would run RentalScape, from Deckard Technologies, on a 12-month $43,120 contract prorated for six months, "up and running by July 1". The software pulls listing data from the rental sites, gets tuned to the town code, and generates non-compliance letters that town staff review before sending. Councilwoman Cate Rogers told the board that "upward of 10 percent of the town's housing stock is advertised on rental platforms", and framed the purchase as a way "that we can look at compliance for the now thousands of rentals that are out there". She was careful to add, though, that the old tradition of a family renting out the house for a season is "not something that I want to impact in any way". If the software flags you in error, meanwhile, you can take that to the Code Enforcement Department and contest it.

What makes software like that effective is a rule almost every East End town already had, which is that your permit number has to appear in the advertisement. Southampton's § 270-9K bars publishing any rental advertisement without the permit number and gives you 10 days to update your listings once a number issues; Southold added the same requirement in 2023; Huntington's page says the number goes on all advertisements. An unpermitted listing therefore announces itself, and the matching is a database exercise rather than an investigation. Your listing is the evidence.

Brokers and agents carry their own exposure, which quietly does a lot of the work. Southampton's § 270-8H makes listing, advertising or showing an unpermitted rental a ground for suspending that agent's permits for two years, plus an in-violation fee, and puts the duty to verify on them. The Town of Babylon goes at the same behavior with money, since § 153-2C makes it unlawful for any person, broker or agent to list or show a unit without a current permit, and § 153-7A now punishes that with $2,500 to $5,000 for a first offense, rising to $7,500 to $10,000 by the third within five years.

The fines on owners are worse than most people expect, so don't treat them as a cost of doing business:

• Southampton: $3,000 to $15,000 for a first conviction under most of Chapter 270, $8,000 to $30,000 for a second inside 18 months, each day a separate violation, plus a mandatory $100 community housing opportunity surcharge. The court may instead impose up to double the rent collected over the whole occupancy.
• Village of Babylon: $500 to $1,000 for a first offense, $1,000 to $3,000 for a second, $2,000 to $5,000 for a third, with your Airbnb listing serving as presumptive evidence of the prohibited use.
• Southold: a $3,000 minimum, with a maximum of "$10,000 or the 14 day published rental rate, whichever is higher", per the East End Beacon's report of the 2023 amendments.

Even Southold's own supervisor conceded at that vote that "the law isn't working" and that the code was "very difficult to enforce", which was true when he said it in 2023. The compliance software is precisely the answer to that complaint, and it arrived three years later.

How to Start a Short-Term Rental Business in Suffolk County

Since the penalties scale with what you collected, the order below still matters, and it's built to fail cheaply and early rather than expensively and late.

1. Find out which government you're actually in. Confirm the town, and confirm whether the parcel sits inside an incorporated village, because the village code supersedes the town's within its own boundary.
2. Read that jurisdiction's minimum stay before anything else. In most of Suffolk County this is where the plan ends, and knowing it now costs you nothing.
3. Check the certificate of occupancy against the house as it stands. Unpermitted bedrooms, basements and garage conversions surface at inspection, and they turn a permit application into a code case.
4. Apply for the town's rental permit or registry number, and budget for the inspection or the licensed professional's certificate that goes with it. Expect a public hearing in Babylon.
5. Register with the Suffolk County Comptroller within 10 days of your first paid night, then display the Certificate of Authority where guests can see it.
6. Put your permit number in every advertisement, on every platform, on day one. This is the single easiest violation to catch and the easiest to avoid.
7. Sort out who collects which tax. Get Form ST-155 from your platform if it handles all your bookings, and set a reminder for the quarterly occupancy-tax return due the 20th of March, June, September and December.
8. Set up the safety and record-keeping items now: posted egress diagram, posted emergency numbers, a working fire extinguisher, $300,000 of liability cover and two years of booking records.
9. Put the expiry date in your calendar. Permits run one year in Huntington, 15 months in Brookhaven and two years nearly everywhere else, and Riverhead wants the renewal filed 60 days before the current permit lapses.

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

Working through those steps, you'll want three different phone numbers, because no single office in Suffolk County can answer the whole question.

The county, for tax and the certificate of authority

The Suffolk County Comptroller's Office runs the occupancy tax, the Certificate of Authority and the registration portal.

New York State, for sales tax

Sales tax registration and Form ST-155 questions belong to the New York State Department of Taxation and Finance, not to the county. Its Sales Tax Information Center answers on 518-485-2889, 8:30 a.m. to 4:30 p.m. on business days.

One practical note before you start dialing, since it affects the links above as well. Several Suffolk County and town websites block automated traffic outright, which is why parts of this guide were read from archived copies of official pages rather than from the live ones. Those pages load normally in a browser, so if something here looks stale, the town's live page is the version to trust.

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

Speaking of pages that won't open, I owe you a straight answer about this section. Reddit blocks automated access and its platform policy bars the commercial use we'd need to mine it, and BiggerPockets' Long Island forum renders navigation without threads, so I haven't read either and I'm not going to characterize conversations I couldn't see. What I can give you is the public record, which is unusually candid in Suffolk County.

Local officials describe a compliance problem rather than a rule problem. The County Comptroller put "substantial non-compliance" in a formal notice to the real estate industry, and East Hampton's Councilwoman Cate Rogers told her own board that upward of 10 percent of the town's housing stock is advertised on rental platforms and that the town now has "thousands of rentals" to check. Southold's supervisor said out loud in 2023 that the law wasn't working and was very difficult to enforce. That's three separate governments saying, in public, that the rules on the books have been widely ignored.

The counterweight in that same record is a distinction officials keep drawing, and it's the one that matters if you own a house here. Rogers was explicit that a family renting out their own house for part of the season is a tradition she doesn't want to touch, whereas what the town is chasing is "outside investors who don't live in the community, buying up housing stock for specifically short-term rentals". Every enforcement tool in this guide points at that second group, which is why the open question is whether the software can tell the two apart. East Hampton said it would study the July and August data before deciding. So that's the thing to watch.

If you're weighing Suffolk against somewhere the whole house can legally go up for a weekend, that comparison is worth making with numbers rather than instinct, and the New York market rankings are a reasonable place to start it. What Long Island teaches, more than any specific rule, is that "is this legal?" and "who exactly says so?" are the same question. Answer the second one first, right down to the village line, and everything else you're weighing gets easier.

Frequently Asked Questions

Can you run an Airbnb in Suffolk County, New York in 2026?

Rarely on a nightly basis. Suffolk County has no ordinance of its own governing short-term rentals, so the decision belongs to your town, and most of the ten towns refuse a rental permit for a transient occupancy. Riverhead bans stays of 29 days or less, Brookhaven's code uses 28 nights, and Southampton prohibits any rental of 14 days or less. The Town of Huntington and the Town of Shelter Island are the exceptions that license short stays outright.

How much is the Suffolk County occupancy tax on a short-term rental?

5.5% of the per-diem rental rate, effective June 1, 2023, under Chapter 523, Article II of the Suffolk County Code. It applies to private residences and tourist homes, not only to hotels. Operators must register with the County Comptroller within 10 days of their first lodging rental, display the Certificate of Authority, and file quarterly returns for periods ending the 20th of March, June, September and December. Airbnb collects this tax for reservations up to 29 nights.

What is the minimum rental period in the Hamptons?

In the Town of Southampton the code defines a rental of 14 days or less as transient and prohibits it, so the first lawful stay is 15 nights. In the Town of East Hampton, a single-family residence rented for two weeks or less on three or more occasions in any six-month period is deemed to be operating unlawfully as a motel. The incorporated villages set their own rules, which are generally at least as strict.

Do I need a permit to rent my house long-term in Suffolk County?

Yes, in most towns. A rental permit or registration is required for any dwelling occupied by someone other than the owner, regardless of the length of the stay. Fees run from $200 in East Hampton to $500 or more in Brookhaven and Islip, and terms are commonly two years. Renting without one is an offense in itself, and in several towns the broker or agent who listed the property is liable too.

What happens if you rent short-term without a permit in Suffolk County?

Penalties vary by town and they're substantial. Southampton's code carries $3,000 to $15,000 for a first conviction, $8,000 to $30,000 for a second within 18 months, and the option of double the rent collected. The Village of Babylon runs $500 to $5,000 by offense number. Separately, the county fines $50 for every day a lodging facility goes unregistered for occupancy tax, and wilful failure to remit is a misdemeanor.
