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

Do you own a place in Mount Vernon and you're weighing whether to put it on Airbnb or Vrbo? Well, the good news is that this Westchester County city on the Bronx border says yes. That's not a given in this part of New York. Mount Vernon's Council wrote short-term rentals into the zoning code in 2024 as a permitted principal use in every residential district, from the R1-7 one-family zones through RMF-15 multifamily, and the city's own text of that law says so in as many words.

The catch is that the permission attaches to you, not to the property. Article XV of Chapter 267 only allows a short-term rental in an "occupied primary residence," so an investor who buys a two-family here and furnishes both units for nightly stays has no legal path at all. Even as a resident, renting the whole unit is capped at 180 days in a calendar year, and the Building and Fire Departments inspect the place before your first permit and again before every renewal. The permit also dies the day the property changes hands.

So let's walk through what it takes to do this properly in 2026: which homes qualify, what the permit involves, the documents you'll be gathering, the layers of lodging tax that stack over a Mount Vernon stay, how the city enforces any of it, and who to call when something doesn't fit your situation. Everything below comes from Mount Vernon's, Westchester County's or New York State's own pages, checked in July 2026, and where a number isn't published I've said so instead of guessing. Assuming you're still deciding between this and a market with no owner-occupancy rule, run both through BNBCalc before you commit.

What are short term rental (Airbnb, VRBO) regulations in Mount Vernon, New York?

That 2024 zoning amendment is where every Mount Vernon rule starts, so it's worth reading closely before anything else.

Article XV defines a short-term rental as an entire dwelling unit, or a room or group of rooms inside one, "made available to rent, lease or otherwise assigned for an occupancy of less than 30 consecutive days," with hotel and motel rooms carved out. Stay at or above 30 consecutive days and you're outside the article entirely, which is the same line the state draws for tax purposes.

The law reached the Council through the normal zoning route. At the public hearing on September 11, 2024 the Clerk read no-objection letters from the Westchester County Planning Board, the Mount Vernon Planning Board and the city's Planning Commissioner, while one resident spoke for it and one against.

Three rules do most of the work, and they're worth taking one at a time.

• Primary residence, always. It's unlawful to operate a short-term rental at a property that isn't an occupied primary residence, and the article requires the home to stay your primary residence "at all times during the term of the permit." Where the property is titled to an LLC or partnership, every owner or member has to live there, which closes the obvious workaround.
• Residential zones only, but all of them. Short-term rentals are permitted in one-family, two-family and multifamily dwellings, in every district where residential use is allowed. The amendment adds them as a permitted principal use in R1-7, R1-4.5, R1-3.6, R2-4.5, RMF-6.75, RMF-10 and RMF-15.
• Some buildings are off the table regardless. No short-term rental is allowed in a multifamily building with an active PILOT agreement with either the Mount Vernon or the Westchester County Industrial Development Agency, in a building that's entirely rent regulated, in any dwelling whose lease or occupancy agreement prohibits it, or in a non-residential building.

One more clause decides how disputes start. Under the article's presumptive-evidence section, offering a property on Airbnb, HomeAway, Vrbo or a similar site, or advertising it anywhere for a period under 30 days, creates a rebuttable presumption that it's being used as a short-term rental. Your listing is the evidence, so nobody has to catch a guest at the door.

Now for the part that trips up people who read about New York City and assume it carries north. It doesn't. The Multiple Dwelling Law, which is what makes whole-apartment Airbnb rentals illegal in the five boroughs, applies by its own terms to cities of 325,000 or more. Mount Vernon isn't close to that, so the NYC-style ban on sub-30-day occupancy in class A buildings never reaches it. Article XV governs instead, with a state and county layer sitting above it.

Starting a Short Term Rental Business in Mount Vernon

Since the permission travels with the resident rather than the building, the business you can still run here is narrower than the zoning map suggests.

Unfortunately for anyone shopping for a dedicated Airbnb property, there's no version of this that works. You can't buy a Mount Vernon house, furnish it and rent it nightly, because you'd have to live in it. You can't hold it in an LLC with silent members either, since all of them would have to live there too.

And you can't inherit a seller's permit. Under Article XV a permit expires automatically "upon a change in ownership or tenancy of the dwelling unit," so a listing that looks like a going concern in a broker's pitch stops being one at closing.

What's left is a resident host business, and it comes in two shapes with very different ceilings. Rent out part of your home while you're physically in residence and there's no annual day limit at all.

Rent the entire unit and you're capped at 180 days in any one calendar year. The city can ask for a platform letter on company letterhead stating how many whole-unit rentals happened that year, plus your own certified letter saying the same. Keep in mind that a rental day counts as any day the property is occupied overnight, so a Friday-to-Sunday booking burns two of your 180.

Tenants get a path too, which is unusual for an ordinance this strict. A renter can apply, though the application has to be signed by the landlord and backed by evidence that the landlord owns the unit, and any later change to the application needs the owner's signature as well. Practically, that means your lease conversation happens before your Airbnb account does.

There's a quieter eligibility filter sitting inside the document list. The application requires proof that the property receives the New York State STAR credit or STAR exemption, and the state's own STAR page limits that benefit to an owner-occupied primary residence where the owners' combined income is $500,000 or less. My read is that the STAR requirement is doing double duty as a primary-residence test. Check it first, since a property that has never had STAR on it is a problem you can't fix with paperwork in the same week.

The demand side is small. AirROI's Mount Vernon page, updated August 8, 2026, counts 44 active listings with an average daily rate of $145, occupancy of 43.3% and average annual revenue of $14,043 across the August 2025 to July 2026 window. Those are aggregator estimates rather than city data, so treat them as a sense of scale, not a pro forma.

Even so, they tell you what the ordinance is aimed at. A spare-room operation at that ADR is supplemental income, which is roughly what the Council said it was legislating for when it wrote that short-term rentals let homeowners "supplement their income to defray the cost of housing."

Short Term Rental Licensing Requirement in Mount Vernon

Supplemental or not, none of it is legal without the permit, and the permit is the step that takes real time.

The rule is blunt. You must obtain a short-term rental permit from the Building Department before the unit or room is advertised, and if you don't advertise, then before it's rented. Article XV makes it unlawful to use, establish, maintain, operate, occupy, rent or lease any property as a short-term rental without one. Advertising first and permitting later isn't a sequencing preference here, it's the violation.

Permits run for one year and renew for further one-year terms on application, compliance and payment of the fee. Every renewal has to be accompanied by a record you've kept through the whole term showing the number of guests and the start and end dates of each stay. Do start that log with your first booking rather than reconstructing it in month eleven.

Inspections are where Mount Vernon differs from most cities that merely register hosts. The Building Department and the Fire Department inspect the property at the time of the initial application and before any renewal, and the unit stays subject to periodic inspections after that. If either inspector determines in writing that the space isn't compliant, you have to stop renting until the problems are corrected, then apply for reinspection and pay an additional fee. That's a real cost in money and in calendar time, so build it into your assumptions.

The fee itself is the one number I couldn't put in front of you. Article XV sets it by reference to the City Fee Schedule rather than naming an amount, and the Department of Buildings fee schedule for 2025 carries no short-term rental line at all. What it does carry is the ordinary counter work: building and equipment permits at a $125 filing fee plus $10 to $15 per $1,000 of estimated cost, certificates of occupancy, multiple-dwelling inspections and so on.

Nor does the city's documents, forms and fees page publish a short-term rental application. As of July 2026, the fee and the form both live at the Building Department counter, so call before you budget around either.

A few conditions can stop an application cold. No permit will be issued where there are unresolved code compliance issues, outstanding City fines or fees, or unpaid taxes on the property. The application also requires certification that the necessary building permits and certificates of occupancy exist for every structure. Clear the old open permit on the deck first.

Revocation is broader than most hosts expect, and it runs through the Building Inspector rather than a court. The grounds are worth knowing in full:

• a permit issued in error, or on a false, untrue or misleading statement;
• an owner or tenant who stops occupying the premises as a primary residence;
• use that creates a hazard or public nuisance, or that hurts the surrounding community's quality of life;
• failure to comply with the conditions of the permit;
• violation of any federal, state or local law, regulation or rule.

There's a counting rule aimed squarely at apartment buildings, too. A permit for a unit in a multifamily building may be revoked if the Police Department or Building Inspector receives three substantiated written complaints in a twelve-month period. "Substantiated" means a complaint about a City law or ordinance backed by other evidence, such as a police report, a photograph or a video.

Assuming a denial, suspension or revocation does land on you, there's still an appeal route, and it's a short one. You get 30 days from the written notice to appeal to the Zoning Board of Appeals under Article IX of the zoning chapter. Assuming the ZBA's decision doesn't satisfy you either, you then have 30 days from the filing of that decision with the City Clerk to bring an Article 78 proceeding.

Violations of Article XV are otherwise enforced through the civil and criminal penalties in Article X of Chapter 267. One caveat applies to this whole guide. The codified code sits on eCode360, which the city's Zoning Ordinance page links to and which blocks automated access, so I worked from the city's own published text of the law and from its Council record instead. Which is also why I won't quote you a fine I haven't read on the page.

Required Documents for Mount Vernon Short Term Rentals

None of those penalties matter much if the application goes in clean. The Building Department decides the form's content "from time to time," so the article's minimum list is the reliable part, and it's the one to assemble before you set foot in Room 210.

• Proof of the STAR credit or STAR exemption for the property.
• A utility bill in the applicant's name.
• The property particulars: the address, the total number of dwelling units in the building, the number of bedrooms and bathrooms in your unit, how many rooms you're proposing to rent, where each one sits in the building, and how many people each will accommodate.
• A signed and notarized certification attesting that you live there as your primary residence, that the property is fit for human habitation and safe, that you'll comply with the permit conditions, that no cellar or attic space will be used as habitable space unless it meets the International Fire, Residential and Building Codes, that the property complies with the City Code and the New York State Code Supplement, and that the necessary building permits and certificates of occupancy exist.
• Your landlord's signature and proof of their ownership, if you're a tenant.
• A responsible person's name and contact details, if you plan to rent the entire unit. That person needs the right to enter and maintain possession of the dwelling, has to be reachable 24 hours a day, and must be able to respond in person within two hours of the City calling.

Two obligations attach after approval and are easy to overlook. Any change to the information in your application has to reach the Building Department in writing within 30 days, and failing to file that change is itself a violation of the section. Then there's the guest log for renewal, which has to run the full permit year.

Mount Vernon Short Term Rental Taxes

Assuming you get through the inspections and are able to start taking bookings, there's still tax to sort out, and it comes from three different governments rather than one.

Charge	Rate	Collected by
New York State and local sales tax	8.375%	NYS Dept. of Taxation and Finance, via the booking platform
Westchester County Room Occupancy Tax	3%	Westchester County Dept. of Finance
Mount Vernon hotel and motel tax	up to 5.875%, authorized but not confirmed adopted	City of Mount Vernon, if it adopts the local law

The sales tax piece is the one that changed most recently. New York extended sales tax to short-term rental unit occupancy statewide effective March 1, 2025, with booking services registering as sales tax vendors and collecting on the occupancies they facilitate. The state's rate table, Publication 718, lists Mount Vernon as its own jurisdiction at 8⅜%, reporting code 5521, effective March 1, 2025. Guests who stay 90 consecutive days or more count as permanent residents and fall out of the tax.

Westchester County's Room Occupancy Tax sits on top of that, and it predates all of this by decades. The county's Department of Finance says a tax of three percent is paid on the rent for every occupancy of a room or rooms in the County, excepting permanent residents and exempt occupants. Every operator has to register within three days of opening under County Code Chapter 285 § 285.06, by filing an Application for Certificate of Authority.

Returns are quarterly. They go through the county's online system within 20 days of the quarters ending in February, May, August and November.

Whether you personally remit either of those depends on your platform. Airbnb's New York occupancy tax page says it collects the Westchester County Room Occupancy Tax of 3% for reservations of 88 nights or shorter, and state sales tax of 7% to 8.875% for reservations of 89 nights or shorter outside New York City. Direct bookings, a personal website, or any platform without an agreement leave the collecting and remitting to you, so do check your own platform's tax settings rather than assuming coverage.

The city layer is the live one this year. New York authorized Mount Vernon to impose its own hotel and motel tax through Senate Bill S7321B, signed on October 16, 2025 as Chapter 452 of the Laws of 2025. The rate may not exceed 5.875% of the per diem rental rate, and the covered list is explicit: "hotels, motels, tourist homes, motel courts, bed-and-breakfast establishments, short-term rentals, vacation rentals, airbnbs, clubs or similar facilities." Anyone staying at least 30 consecutive days is exempt.

That authorization expires on December 31, 2027, and it only becomes a real tax once the Council adopts a local law imposing it. I couldn't confirm on any city page that Mount Vernon has done so as of July 2026, so I won't tell you that you owe it. Do be aware that it can arrive with one Council vote, and that Article XV already requires a permitted host to "comply with any applicable occupancy tax in effect."

Your rental income is ordinary taxable income on top of all this, and the room-in-your-own-home shape of a legal Mount Vernon rental means apportioning most expenses between personal and rental use. That's fiddlier than a whole-unit rental, so it's worth getting a bookkeeper's eye on the first year.

Mount Vernon wide Short Term Rental Rules

Tax aside, Article XV's operating standards apply to every permitted rental in the city, and they read like a fire marshal wrote half of them.

Occupancy is set by room size rather than by house. The maximum is one person in a sleeping room between 70 and 100 square feet, and two people where the room is larger than 100 square feet. The Building Inspector can also disqualify a space as a sleeping room over egress, safety or over-occupancy concerns.

Every sleeping room needs a way out. That means an exterior exit opening directly outside, or an emergency escape or rescue window meeting the applicable requirements, though the Inspector may approve other means of egress at their reasonable discretion.

The safety kit is specified item by item: a working smoke detector inside each sleeping room and another on the ceiling or wall immediately outside each one, carbon monoxide detectors in any unit with a fuel-burning appliance or other CO source, and at least one functioning, inspected fire extinguisher in the dwelling unit. All of it as approved by the Building Inspector, which is what those renewal inspections are checking.

Then there's the posting and housekeeping layer, which is where hosts most often fall short without noticing.

• The permit number goes in every advertisement if you advertise the rental.
• A valid permit must be posted conspicuously inside the unit, along with a safety and egress plan, and your house rules if you have any.
• A written notice on a form provided by the Building Department covering City parking laws, garbage and rubbish rules and schedules, and snow removal, and naming whoever answers complaints, has to be left in a conspicuous spot inside the unit and kept there.
• Weekly garbage removal has to be arranged during all short-term rental occupancies, under City Code Chapter 140.
• Off-street parking as regulated by Article VIII is required, and parking on any part of the lawn is prohibited.
• A house number visible from the street has to be maintained.

Events are out. A short-term rental can't be used for any other purpose, commercial or otherwise, "such as concerts, weddings, or other large gatherings or events." The owner also has to use best efforts to stop guests creating noise, disturbance or disorderly conduct, or breaking the City Code and the laws on alcohol and illegal drugs. Whole-unit hosts carry that 24-hour agent obligation on top, with its two-hour in-person response window.

Above the city sits a state framework that's still settling. New York's 2025 amendments, enacted as Chapter 99 of the Laws of 2025, moved short-term rental registration to a county-run model with a county opt-out.

Real Property Law § 447-b then attaches its own duties to a registered unit: a posted evacuation diagram, posted emergency numbers for police, fire and poison control, a working fire extinguisher, minimum liability insurance of $300,000, and two years of guest records. Those duties are expressly not enforceable against a host "before such time as a county has established a registry."

Which brings up the gap I can't close for you. Going through Westchester County's own finance and legislative pages in July 2026, I couldn't find a published decision on whether the county stood up a registry, joined a shared one, or opted out. The deadline for making that choice has already passed.

Remember that once a county has a registry, the $300,000 insurance minimum stops being a good idea and becomes a requirement, so ask the county directly before you assume your homeowner's policy covers you. Our Westchester County guide tracks the county layer, and the New York statewide guide covers how the registry law works across the rest of the state.

Does Mount Vernon Strictly Enforce STR rules? Is Mount Vernon Airbnb Friendly?

Even with that county question open, the city half of the enforcement picture is clear enough, and "strictly" is the wrong word for it. Mount Vernon built the checks into the permit instead, which is harder to dodge than an inspector on patrol and easier to live with once you qualify.

Look at the mechanics rather than the rhetoric. Your listing itself creates a rebuttable presumption of short-term rental use, so an unpermitted host is presumed in violation from the moment the ad goes up. The Building Department also has to maintain a list of every short-term rental unit in the city and update it every six months, which means the city knows its own permitted inventory and can hold it against what's visible on the platforms.

Inspections happen at application and again at every renewal, rather than once. And for a multifamily unit, three substantiated written complaints inside twelve months can cost the permit outright, with substantiation resting on ordinary evidence like a police report or a photograph.

Set that against the AirROI count of 44 active listings and the shape of the market gets clear enough. This is a small, mostly residential city where neighbors know which house is which, complaints are the trigger, and the Building Inspector holds the pen on revocation. Enforcement here doesn't need a task force.

So is it Airbnb friendly? For a resident host, honestly yes, and more so than most of Westchester. You get a defined legal path, permission in every residential district, no cap at all on renting part of your home while you're there, and an appeals route through the ZBA.

For an investor, no. The primary-residence rule, the 180-day whole-unit cap and the permit expiring on change of ownership together remove the entire non-owner-occupied model. Compare that with the Bronx County guide a few blocks south, where the registration regime is tighter still, and Mount Vernon starts to look like the more workable end of a difficult region.

How to Start a Short Term Rental Business in Mount Vernon

Assuming Mount Vernon still looks workable to you after that, the order of what comes next matters more than it might seem. The early steps are free, and they tell you whether the later ones are even worth the trouble.

1. Confirm the home is your primary residence and carries STAR. No STAR credit or exemption on the property means an application you can't complete. If you're a tenant, have the landlord conversation now, because their signature is part of the filing.
2. Check the building's status. An active PILOT with either Industrial Development Agency, a fully rent-regulated building, or a lease that prohibits short-term rentals all rule the unit out before you spend anything.
3. Clear what's outstanding. Unresolved code issues, unpaid City fines or fees, and unpaid taxes each block a permit, and you'll be certifying that building permits and certificates of occupancy are in place for every structure on the property.
4. Decide whole-unit or room share. Whole-unit costs you the 180-day ceiling and the 24-hour responsible agent. Rooms while you're in residence carry neither, so the model you pick changes the compliance load as much as the revenue.
5. Fix the safety items before the inspection. Smoke detectors in and outside every sleeping room, CO detectors where anything burns fuel, an inspected fire extinguisher, and an egress window or exterior exit for each sleeping room.
6. Call the Building Department for the application and the fee, since neither is published online. Room 210 at City Hall, 914-665-2483.
7. Get inspected by Buildings and Fire, then collect the permit before you list anything anywhere.
8. Set up the postings on day one: permit, safety and egress plan, the city's parking, garbage and snow notice, and your house rules.
9. Register for tax. File the county's Application for Certificate of Authority within three days of opening, then confirm what your platform collects and remits so you're not double-paying or under-paying.
10. Keep the log all year. Guest counts and stay dates, plus whole-unit day totals against the 180-day cap, because renewal requires the record and the city can ask a platform to confirm it.

Who to contact in Mount Vernon about Short Term Rental Regulations and Zoning?

Most of the steps above run through one office, though the tax questions belong to two governments that aren't the city.

Permits, inspections and the ordinance itself

The Mount Vernon Department of Buildings issues short-term rental permits, runs the inspections, holds the registry list and handles revocations.

• Address: City Hall, Department of Buildings, Room 210, Roosevelt Square, Mount Vernon, NY 10550
• Phone: 914-665-2483
• Email: [email protected]
• Commissioner: Patrick G. Holder, R.A.

Those details come from the department's own 2026 Certificate of Occupancy application and the city directory. Because no short-term rental form appears in the city's online document center, this is the office to call rather than a page to download from.

Zoning interpretation and appeals

The Department of Planning and Community Development administers the zoning ordinance and staffs the Zoning Board of Appeals, which is where a denied, suspended or revoked permit goes within 30 days.

• Address: Mount Vernon City Hall, 1 Roosevelt Square N, Mount Vernon, NY 10550
• Phone: 914-840-4029
• Email: [email protected]
• Commissioner: James Rausse

Fire safety

The Mount Vernon Fire Department inspects alongside Buildings at application and renewal. Fire Commissioner Kevin Halt's office is reachable at 914-665-2626, per the city directory.

County room occupancy tax

The Westchester County Department of Finance, Room Occupancy Tax Division registers operators and takes the quarterly returns.

• Address: County of Westchester, Department of Finance, Room Occupancy Tax, 148 Martine Ave., White Plains, NY 10601
• Phone: 914-995-3462
• Online: the county's Room Occupancy Tax page carries the registration forms and the filing system

State sales tax

Sales tax registration and returns belong to the New York State Department of Taxation and Finance. Its Sales Tax Information Center answers on 518-485-2889, 8:30 a.m. to 4:30 p.m. on business days, and vendor registration runs through Form DTF-17.

What do Airbnb hosts in Mount Vernon on Reddit and Bigger Pockets think about local regulations?

Those offices will answer the legal questions. What they can't tell you is how hosting here feels from the inside, and public sentiment on a market this small is thin, so I'd rather say that than dress up a handful of threads as a survey.

Searching BiggerPockets in July 2026 turned up no discussion that substantively addresses Mount Vernon's short-term rental ordinance. Westchester comes up in investor threads, though the conversation is almost always about multifamily buy-and-hold rather than nightly rentals. Reddit I don't quote here as a matter of policy, since its platform terms don't permit the kind of commercial data use these guides would require, and asserting what a thread says without having read it is worse than saying nothing.

What I can point to is the record from the city's own process. At the September 2024 public hearing, one resident spoke in favor and one spoke against, while all three planning bodies that reviewed the law filed no objection. That's about as quiet as a rule change gets, and it matches how the ordinance reads: permissive on where you can host, firm on who gets to.

Two things are worth watching if you're going to operate here. The first is the pending city hotel tax, since a Council holding a state authorization that expires in December 2027 has an obvious reason to act. The second is the county registry question, which decides whether the state's $300,000 insurance minimum and two-year record rule bite in Westchester.

Neither is settled. Both would change your cost base rather than your legality, and before committing to any of it, the New York market data is the faster way to check whether the revenue justifies the compliance.

Owner-occupancy rules like this one are becoming the default answer across the New York suburbs, and they reward a different operator than the spreadsheet model that took hold in 2021. The question worth asking about any market with one isn't whether you can get a permit. It's whether the business still works when the person running it has to be home.

Frequently Asked Questions

Can you run an Airbnb in Mount Vernon, New York in 2026?

Yes, if the home is your own primary residence. Mount Vernon's zoning code permits short-term rentals in every residential district, but only in an occupied primary residence, and only with a short-term rental permit from the city's Building Department. An investor-owned property with no resident owner or tenant has no legal path. Renting an entire unit is limited to 180 days per calendar year, while renting part of your home with you in residence has no day limit.

How much does a Mount Vernon short-term rental permit cost?

Mount Vernon's ordinance sets the permit fee by reference to the City Fee Schedule instead of naming an amount, and the Department of Buildings fee schedule published for 2025 lists no short-term rental line. No application form appears in the city's online document center either. As of July 2026 the amount isn't published anywhere official, so contact the Department of Buildings at 914-665-2483 for the current fee and the form.

What taxes apply to a short-term rental in Mount Vernon?

Two apply today. New York State and local sales tax runs at 8.375% in Mount Vernon under the state's Publication 718 rate table, and Westchester County adds a 3% Room Occupancy Tax that requires operators to register within three days of opening. Airbnb states that it collects both for qualifying reservations. A city hotel and motel tax of up to 5.875% was authorized by Chapter 452 of the Laws of 2025, though a Mount Vernon local law imposing it could not be confirmed as of July 2026.

How long does a Mount Vernon short-term rental permit last?

One year. Renewal is for further one-year terms, requires a fresh application and fee, and has to be accompanied by a record kept through the whole permit year showing guest numbers and the start and end dates of every stay. The Building Department and Fire Department inspect the property before each renewal as well as at first application. A permit also expires automatically when ownership or tenancy of the unit changes, so it can't be sold with the house.

Can you lose a short-term rental permit in Mount Vernon?

Yes, through a fairly wide door. Mount Vernon's Building Inspector can revoke a permit issued on a false statement, one where the owner or tenant stops living at the property, or one where the use creates a hazard or a public nuisance. For a unit in a multifamily building, three substantiated written complaints inside twelve months are grounds on their own. A revocation can be appealed to the Zoning Board of Appeals within 30 days.
