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

Do you own a place in Onondaga County, New York and you're weighing whether to put it on Airbnb or Vrbo? Well, the good news is that you can. Onondaga County has never banned short-term rentals, and neither has Syracuse. What changed, and changed recently, is that the county finally caught up to them: since September 2025, a short-term stay here gets treated much the way a hotel room has been treated since 1975, registered, taxed, and checked on.

That catch is worth sitting with before you list anything. Local Law No. 9 of 2025 rewrote the county's decades-old Hotel Room Occupancy Tax Law to define what a short-term rental is, require every host to register with the county, and apply the same 7% tax hotels already pay. Syracuse adds its own wrinkle on top of that. The city runs a separate Rental Registry Certificate for one- and two-family properties, and even after reading the city's own pages closely, it's genuinely unclear whether that certificate is meant to cover a nightly Airbnb stay the same way it covers an ordinary lease.

So let's walk through what it actually takes to do this properly: what the county requires in 2026, what Syracuse asks for on top of that, the taxes stacking up on a single booking, and how hard any of this gets enforced so far. Every figure below comes from Onondaga County's or Syracuse's own pages, or from Airbnb's own tax-collection page, checked as of July 2026. If you're weighing a Syracuse-area property against other Central New York markets, run the numbers through BNBCalc first.

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

Before you run those numbers, it helps to know exactly which law governs a short-term rental here, because two different governments touch it, and they don't touch it the same way.

Start with the negative case, since it's the one first-time hosts worry about most. Nothing in Onondaga County's code or Syracuse's code bans short-term rentals outright, and neither government has tried to, at least not in anything my research turned up. New York State doesn't force the issue either. The state's own training materials for local governments say plainly that it's "up to each municipality to define, prohibit and/or regulate short term rentals as they choose" (NYS DOS training presentation), though one piece of background state law does bind every locality regardless of what it decides.

That background law is the Multiple Dwelling Law, and it's the one that makes New York City's whole-apartment ban possible. It only reaches cities of 325,000 residents or more, under Multiple Dwelling Law § 3, and right now that's only New York City and Buffalo. Syracuse, at roughly 146,000 residents, doesn't come close. So if you've read an older or more generic guide that imports NYC's 30-day rule to Onondaga County, do treat that as wrong here. Nothing in state law forces Syracuse or the towns around it to classify a short stay as illegal.

What governs a short-term rental in Onondaga County arrived far more recently, and it came from the county rather than the city. On September 2, 2025, the County Legislature adopted Local Law No. 9 of 2025, rewriting the county's Hotel Room Occupancy Tax Law, on the books since 1975, to define a "Short Term Rental Unit" for the first time and fold it into the same tax and registration system hotels have always used. Local Law No. 9 relies on Chapter 99 of the Laws of 2025, the state statute that gave counties the choice to build their own short-term rental registry or opt out, and Onondaga's Legislature chose to build one rather than pass on it.

Put the pieces together and three obligations fall out, and no amount of paperwork makes any of them optional:

• Register with the county and keep the Certificate of Authority current. Registration runs two years, and the certificate has to be posted in the unit and named on every listing (Local Law No. 9 of 2025, §24(f)).
• Collect and remit the county's Room Occupancy Tax, 7% of the rent. That rate has applied to hotels since Local Law No. 1 of 2021 raised it from 5%, and LL9 extended it to cover short-term rentals too.
• Clear the law's safety and insurance floor. A posted evacuation diagram, posted emergency numbers, a working fire extinguisher, and at least $300,000 in liability insurance, which a booking platform's own coverage can satisfy if it meets or beats that figure (LL9, §24(i)).

Starting a Short-Term Rental Business in Onondaga County

Those three obligations are the county's floor, not the whole picture, because the individual town or village you're in still gets a say. LL9 says as much directly: it lets any city, town or village inside the county pass its own local law "prohibiting or further limiting" short-term rentals, and the county's registration system doesn't override that (LL9, §24(e)). Onondaga County has nineteen towns and a handful of incorporated villages outside Syracuse, from Camillus to Manlius to Cicero, and each keeps its own zoning code. Before you buy or convert anything, do check your specific municipality's zoning office, since a county-level "yes" doesn't guarantee a village-level one.

Assuming your address clears local zoning, you still have to clear the county's own registration process. Who qualifies is broader than you might expect. LL9 defines a "Short-Term Rental Host" as anyone in lawful possession of the unit, so an owner or a tenant can both register, provided a tenant has the owner's written consent on file and can produce it to the county on request (LL9, §24(f)(3)). Once you're registered, the booking side of the business is what you'd expect anywhere else: nightly or weekly stays, a listing on Airbnb or Vrbo, the 7% county tax layered onto the state sales tax covered further down.

What you won't find in Onondaga County is the New York City problem of an entire-apartment ban, so the market here looks a lot more like a normal Central New York rental market with a tax and a registry attached than a fight over legal status. If Syracuse's numbers don't pencil out on their own, the Oneida County guide and the Monroe County guide cover two neighboring Central and Western New York markets that took different paths on their own registries, which is worth knowing if you're comparing sites across the region.

Short-Term Rental Licensing Requirement in Syracuse

That comparison is a useful segue, because Syracuse itself is where this gets genuinely murky, and I want to be straightforward about that rather than paper over it. The city runs a Rental Registry Certificate through its Division of Code Enforcement, required for "each one-family and/or two-family non-owner occupied dwelling rented or leased" in the city, at a fee of $150.00, valid three years or until the property sells (City of Syracuse Rental Registry Certificate page). I read that page, and the city's older FAQ version of it, and neither one uses the words "short-term," "Airbnb," "transient," or "vacation rental" anywhere. The certificate, on its face, describes ordinary landlord-tenant leasing, not nightly stays.

I couldn't confirm on a primary source whether the city treats an Airbnb booking as "rented or leased" for registry purposes, so I'm not going to assert either way. What I can say is that Local Law No. 9 of 2025 only lets a municipality skip the county's registry if it already runs "its own Short-Term Rental Unit registry or registration system" (LL9, §24(m)), and from what I can tell, Syracuse's general landlord registry doesn't meet that bar. It's not short-term-rental-specific in the way the law describes. If that reading holds, Syracuse hosts register with the county under LL9, the same as everyone else in Onondaga County, and the city's $150 certificate is a separate question you'll want to put to the Division of Code Enforcement directly rather than assume your way through.

Syracuse does have one more tax wrinkle worth knowing about here, since it touches "Syracuse" specifically rather than the whole county. State law separately authorizes the city, not the county, to charge up to a 2% hotel occupancy tax of its own under NY Tax Law § 1202-nnn, and Syracuse's Common Council adopted that tax on January 21, 2025. Whether it reaches short-term rentals is another thing I couldn't pin down. The statute's own "hotel" definition tracks traditional lodging language rather than naming platforms the way the county's amended law does, and tellingly, Airbnb's own New York tax page lists the county's 7% tax by name but never mentions a separate Syracuse charge (Airbnb, New York occupancy tax collection). Treat that as suggestive rather than proof, and check with the city's Finance office before you assume it doesn't apply to you.

Required Documents for Onondaga County, New York Short-Term Rentals

Given how much of that hinges on paperwork you'll be asked to produce, it's worth gathering the county's list before you touch a listing calendar. For the county registration itself, expect to show:

• Proof you're the owner, or written consent from the owner if you're a tenant. A tenant who can't produce that consent doesn't qualify for registration at all (LL9, §24(f)(3)).
• Proof of liability insurance meeting the $300,000 minimum, unless your booking platform's own coverage already meets or beats that number.
• The unit's safety setup, which the county can ask you to certify: a posted evacuation diagram, posted emergency numbers for police, fire and poison control, and a working fire extinguisher.

Keep in mind the paper trail doesn't stop once you're approved. Hosts have to hold onto guest-stay records, including dates, guest counts, cost and the tax collected, for two full years after the calendar year each stay happened in, and produce them for the county on request (LL9, §24(j)). If you also end up applying for Syracuse's Rental Registry Certificate, that's a separate application with its own inspection and its own paperwork, so don't assume the county file covers it.

Onondaga County Short-Term Rental Taxes

Once you've got the paperwork sorted, tax is the next thing that costs real money, and in Onondaga County it stacks in three layers rather than one.

Charge	Rate	Collected by
Onondaga County Room Occupancy Tax	7% of the rent	Onondaga County Department of Finance, though Airbnb collects it automatically
City of Syracuse Hotel Room Occupancy Tax	up to 2%, applicability to short-term rentals unconfirmed	City of Syracuse
New York State and Onondaga County sales tax	8% combined (4% state, 4% county)	NYS Dept. of Taxation and Finance, generally via your booking platform

The county tax is the one most hosts here will feel most directly. It's 7% of the rent, and it doesn't apply below a rate of $2.00 per day or to a guest who stays 90 consecutive days or more, who counts as a permanent resident instead of a transient guest (LL9, §24(p)). Airbnb already handles this tax automatically on any booking it processes. Airbnb's own New York tax page confirms the rate directly: "Onondaga County Hotel Room Occupancy Tax: 7% of the listing price including any cleaning fees, for reservations 29 nights and shorter." If you book direct, or through a platform without a collection agreement, that responsibility falls back on you, and the county wants a return filed quarterly regardless, due April 20, July 20, October 20 and January 20 (onondaga.gov/finance/occupancy).

State sales tax is the second layer, and it's newer than you might assume. Effective March 1, 2025, New York extended sales tax to short-term rental occupancy statewide wherever the rate is more than $2.00 per unit per day (NYS Dept. of Taxation and Finance). In Onondaga County that combines to 8%, split evenly between the 4% state rate and the county's own 4% local rate. Booking services register as sales tax vendors and generally collect it on your behalf, and Airbnb's own page confirms it collects "State Sales Tax: 7-8.875%... for reservations 89 nights and shorter outside New York City," which is the statewide range that includes Onondaga's 8%.

Syracuse's own 2% city hotel tax is the layer I genuinely can't resolve for you, since it's uncertain whether it reaches short-term rentals at all, as covered above. Just make sure you keep an eye on it if the city updates its guidance, because a rate that currently sits in a gray area could firm up into an obligation without much notice. Your best move in the meantime is a quick call to Syracuse's Finance office before you set prices, rather than guessing either way. Once the tax picture is settled, it's worth comparing what a Central New York property actually clears against other spots in the state, and the state-level numbers on BNBCalc Markets are a reasonable place to start that comparison.

New York Wide Short-Term Rental Rules

Zooming out from Onondaga's own tax stack, it helps to see how much of this framework is state law wearing a county's name.

New York doesn't preempt local short-term rental regulation the way some states do; it leaves the choice to each city, town, village and county, which is exactly why Onondaga's rules look different from Oneida's or Monroe's next door. What the state did build is the registry framework itself. Real Property Law Article 12-D, enacted through Chapter 99 of the Laws of 2025, let every county either run its own short-term rental registry, join a shared one, or opt out entirely by a set deadline. Onondaga chose to run its own, which is exactly what Local Law No. 9 of 2025 built. Monroe County, by contrast, opted out, which is worth knowing if you're weighing Syracuse against Rochester as markets.

The other statewide layer is the sales tax change covered above: the March 1, 2025 extension of New York's sales tax to short-term rental occupancy, plus the requirement that booking services register as vendors and collect it. Neither of those state rules bans anything. They mean a short-term rental in New York is taxed a little differently than it was in 2024, no matter which county you're in. Our New York statewide guide walks through that framework in more depth, and it's worth reading if you're weighing markets outside Onondaga entirely.

Does Onondaga County Strictly Enforce STR Rules?

Given how new all of this is, the honest answer is that enforcement is just getting started, and it's worth saying that plainly rather than pretending the county has a long track record here.

The mechanism, though, is built to have teeth once it runs for a while. LL9 makes it unlawful for a booking service to collect a fee on a listing the county hasn't verified as registered, and requires those platforms to report guest-stay data to the county every quarter starting ninety days after the law took effect (LL9, §24(k)-(l)). That's the same checkout-layer approach New York City leans on with Local Law 18, applied to a county rather than a five-borough city. Penalties escalate rather than hit hard immediately. A first and second violation get a warning notice with a seven-day cure period, a third draws a fine of up to $200, and anything after that can run up to $500 per day (LL9, §24(n)). Operating without a Certificate of Authority at all carries its own separate penalty, up to $500 the first day and $200 for each day after, capped at $10,000 (onondaga.gov/finance/occupancy).

The county has also put real money behind running the registry rather than leaving it on paper. Legislators approved funding for registry software alongside the tax expansion. Chief Fiscal Officer Kristi Smiley told legislators the platforms would handle most of the remittance work themselves, so it "will not be on the owner to necessarily remit the sales or the room occupancy tax every time" (WAER, September 2025). Legislator Colleen Gunnip framed the registry's real purpose as visibility rather than punishment. "With the registry," she said, "we're going to have a better handle as to how many there are in our community." I couldn't find any lawsuits or public enforcement actions tied to LL9 as of my last check in July 2026, which makes sense given the law is still under a year old. Watch out for that changing quickly once the registry has a full year of data behind it, because a county that recently spent money building enforcement infrastructure tends to eventually use it.

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

Given everything above, here's the order that saves the most time, since checking eligibility before you spend money beats fixing paperwork after the fact.

1. Confirm your municipality allows it. Check zoning with your specific town or village, or with Syracuse's Division of Code Enforcement if you're inside city limits, before you commit to a property.
2. Line up $300,000 in liability insurance, or confirm your booking platform's coverage meets that floor on its own.
3. Register with Onondaga County and secure your Certificate of Authority, keeping in mind the registration runs two years before you'll need to renew it.
4. Post the required safety items inside the unit: the evacuation diagram, emergency contact numbers, and a working fire extinguisher.
5. List your registration number on every listing and offering, since an unregistered listing exposes both you and the booking platform to fines.
6. Set up quarterly filing for the county's 7% tax, due April 20, July 20, October 20 and January 20, even on bookings where your platform already collects it for you.
7. Confirm your sales tax setup with your booking platform, since most of the 8% combined state and county rate should already be handled for you if you're listed on Airbnb or Vrbo.
8. Check with Syracuse's Finance office if your property sits inside the city, given how unsettled the city's own $150 rental registry and 2% hotel tax remain for short-term stays.
9. Keep two years of guest-stay records on hand, since the county can request them and the clock runs from the end of the calendar year each stay occurred in.

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

Those four offices are worth having on hand precisely because so much of this is new, and that newness shapes how hosts here talk about it. I want to be upfront that I couldn't find a live, specific Reddit or BiggerPockets thread dedicated to Onondaga County or Syracuse short-term rentals when I searched, so what follows is my read of the visible public record rather than a survey of host opinion, and I'd weigh it accordingly.

The clearest signal is timing. A county that only built its registry in September 2025 hasn't had time to generate the kind of enforcement war stories that shape investor sentiment in older, stricter markets like New York City. Central New York's investor conversation, from what I can tell, still centers more on ordinary landlord economics, cash flow, tenant turnover, winter heating costs, than on short-term rental compliance specifically, because the compliance regime is too young to have bitten anyone yet.

The one theme that does show up consistently in local reporting is confusion about who collects what. County officials themselves have leaned on the fact that platforms handle most of the remittance automatically, which suggests the county expected hosts to find the layered tax structure genuinely confusing rather than obviously self-explanatory. That tracks with what turned up researching this guide: even reading the primary documents directly, reconciling the county's 7% tax, Syracuse's uncertain 2%, and the state's 8% combined sales tax took real digging. If it took that much effort with the source documents open, it's a fair bet it takes hosts even longer working from secondhand summaries.

What that points to more broadly is a lesson that outlasts Onondaga County specifically: a market's rules aren't done changing just because a law passed. A registry that's a year old, backed by fresh funding and a fiscal officer's stated intent to "have a better handle" on the local market, tends to sharpen rather than soften as it matures. Treat any short-term rental guide, this one included, as a snapshot of a moving target rather than a settled answer.

Frequently Asked Questions

Can you legally run an Airbnb in Onondaga County in 2026?

Yes. Neither the county nor any of its municipalities bans short-term rentals outright, and the Multiple Dwelling Law's 30-day restriction that governs New York City doesn't reach Syracuse or any other city in the county, since it only applies to cities of 325,000 or more residents. What's required instead is registration with Onondaga County under Local Law No. 9 of 2025, a Certificate of Authority, and collection of the county's 7% Room Occupancy Tax, on top of whatever your specific town or village zoning allows.

How much does short-term rental registration cost in Onondaga County?

The law itself leaves the exact registration fee to be set by the county rather than fixing it in the statute, and I couldn't confirm a published dollar figure on the county's own Room Occupancy Tax page as of this guide's research. What's confirmed is the structure: registration runs two years, renewable, and failing to register at all can cost you up to $500 for the first day of unregistered activity plus $200 for each day after, capped at $10,000. Check the county's registration portal directly for the current fee before you apply.

What taxes apply to a short-term rental in Onondaga County?

Three layers can apply. The county's Room Occupancy Tax is 7% of the rent, which Airbnb already collects automatically on bookings it processes. New York State and Onondaga County sales tax adds another 8% combined, generally collected by your booking platform as well. Syracuse also has its own 2% hotel tax authorized under state law, though whether it reaches short-term rentals specifically remains unconfirmed, so check with the city's Finance office if your property sits inside city limits.

Do I need a separate license from the City of Syracuse to run an Airbnb there?

That's genuinely unclear, and this guide couldn't resolve it on a primary source. Syracuse runs a Rental Registry Certificate for one- and two-family non-owner-occupied properties, but its own pages never mention short-term rentals, Airbnb, or transient stays anywhere. Local Law No. 9 of 2025 only exempts a municipality from the county's registry if it already runs its own short-term-rental-specific registry, and Syracuse's general landlord registry doesn't appear to meet that description. Call the Division of Code Enforcement to confirm before you assume either way.

What happens if you operate an unregistered short-term rental in Onondaga County?

A first and second violation draw only a warning, with a seven-day window to fix the problem, so an honest mistake usually isn't fined right away. A third violation can cost up to $200, and each one after that runs as high as $500 per day. Operating with no valid Certificate of Authority carries its own penalty, up to $500 the first day and $200 each day after, capped at $10,000, and platforms are barred from processing fees on an unregistered listing once the county flags it.
