NYC Local Law 18 short-term rental registration with OSE

Last updated 2026-07-25

What is NYC Local Law 18 and what does it actually require?

Local Law 18 of 2022 is the law that created New York City's short-term rental registration law. It took effect for enforcement purposes on September 5, 2023, after the city finished building the registration system and giving booking platforms time to comply ^[1]. The law requires anyone who wants to host a short-term rental (a rental of a dwelling unit for fewer than 30 consecutive days where the host doesn't have exclusive use of the entire unit for the whole stay) to register with the Mayor's Office of Special Enforcement, commonly called OSE. Once registered, you get a registration number. Booking platforms like Airbnb and Vrbo are legally barred from processing transactions for New York City listings that don't have a valid registration number attached ^[2]. This is not a separate 'you can now rent your whole apartment on Airbnb' law. It's closer to the opposite. Local Law 18 codifies rules that already existed under the city's Multiple Dwelling Law and just builds enforcement teeth around them, mainly by cutting off the platforms' ability to process unregistered listings ^[1][2].

Who actually has to register with OSE?

You need to register if you plan to rent out part of your home, or your whole home, for a stay under 30 days, and you intend to advertise that stay on a booking platform. That includes owners and tenants, though tenants need to confirm their lease and building rules actually allow subletting at all. Here's the part that trips people up: registering doesn't mean you're now allowed to do a whole-apartment rental while you're away. Under the Multiple Dwelling Law provisions Local Law 18 enforces, most short-term rentals in Class A multiple dwellings (typical apartment buildings) require the permanent resident to be present in the unit during the guest's stay, and the total number of guests is capped at two unless they're part of the host's immediate family ^[3][1]. So in practice, registration is aimed at hosts doing home-share style rentals, renting a spare bedroom while they live there, not people trying to run a full-time Airbnb out of an empty unit. If you own a one- or two-family house (not a multiple dwelling), different and generally looser rules may apply, but you still need to register if you're advertising short-term stays through a platform ^[1].

How do you register a short-term rental with OSE?

Registration happens through the OSE short-term rental registration portal, not through your local buildings department or a general business license process. You'll need to provide details about the unit, proof you live there (if the host-presence rule applies), and information about the building ^[1]. OSE reviews applications and either registers the unit, denies the application, or asks for more information. As of city guidance, OSE aims to act on applications, but processing times have varied and backlogs have been reported since the portal opened, so don't assume same-day or same-week approval ^[1]. Once approved, you get a registration number. That number has to be included in your listing on any booking platform. If a platform can't verify the number against OSE's registration list, it's required to block the transaction under Local Law 18 ^[2]. If you're also dealing with a building-level rental license or a separate landlord registration in another jurisdiction, keep those processes distinct in your head. OSE registration covers the short-term rental use specifically. For general background on running a rental property as a landlord in a licensed city, see our overview on landlord basics.

What happens if you rent short-term without registering?

Fines are real and can add up fast. The city can issue civil penalties, and violations tied to illegal short-term rental activity under the Multiple Dwelling Law and Local Law 18 framework can run up to $5,000 per violation, depending on the specific provision violated and whether it's a repeat offense ^[3][1]. Beyond city fines, there's a practical enforcement layer that hits harder for a lot of hosts: platforms cutting you off. Airbnb and other platforms operating in New York City are required to stop processing bookings for unregistered units, meaning an unregistered listing may simply stop generating income even before the city issues a fine ^[2]. Landlords and co-op or condo boards have their own enforcement angles too. Many proprietary leases and condo bylaws separately prohibit short-term subletting, so you could face a lease violation or board action on top of any city penalty. If you got a notice or a fine already, don't guess at your next move; confirm the specific code section cited with your building's management or with OSE directly before you respond.

How is Local Law 18 different from a rental license or registration in other cities?

Most rental licensing programs around the country (the kind our other city guides cover) are about long-term rental housing: making sure a unit rented for six months or a year meets safety codes, has a certificate of occupancy, and is registered with a housing department. Local Law 18 is narrowly about short-term stays, under 30 days, booked through platforms. That means a landlord can be fully compliant with their city's regular rental registration or licensing program and still be violating Local Law 18 if they're also running short-term stays without OSE registration. The two systems don't substitute for each other in New York City. If you're comparing how strict NYC is relative to other short-term rental cities, the honest answer is: very strict, because the underlying host-presence and two-guest-cap rules predate Local Law 18 and come from the Multiple Dwelling Law itself ^[3]. Local Law 18 mainly added the registration requirement and platform enforcement mechanism on top of rules that already made most whole-unit short-term rentals illegal in multiple dwellings.

Does Local Law 18 apply if you only rent occasionally, like a few weekends a year?

Yes, frequency doesn't exempt you. If the stay is under 30 consecutive days and you're advertising through a booking platform, the registration requirement applies whether you do it twice a year or every week. The host-presence and two-guest rules under the Multiple Dwelling Law also don't have a carve-out for occasional use. If your unit is in a Class A multiple dwelling and you won't be present during the stay, that's not a registration problem you can fix, it's a use that's not permitted regardless of registration status ^[3][1]. The only way occasional short-term rentals cleanly avoid the whole framework is if the stay is 30 days or longer, which puts it outside Local Law 18's definition of a short-term rental entirely.

What can OSE or a city inspector actually check?

OSE enforcement staff can investigate complaints, which often come from neighbors, building management, or tips generated by monitoring booking platforms. Investigations can include site visits, records requests to platforms, and cross-referencing a listing against the OSE registration database ^[1]. Generally speaking, in any rental inspection context (whether it's OSE checking short-term rental compliance or a housing department doing a standard rental unit inspection), what an inspector can look at is tied to the specific code or law they're enforcing: things like occupancy limits, safety equipment, exits, and, for OSE specifically, evidence of who's actually staying in the unit and for how long. Inspectors generally can't search unrelated areas of a home or demand entry without proper authority; if you're unsure of your rights during any inspection, ask the inspector to identify the specific legal authority for the visit before letting them in. If you're preparing for a standard rental license inspection (separate from OSE short-term rental enforcement), our brand's $79 City Rental License & Inspection Prep Packet walks through the common line items landlords get flagged for, smoke detectors, egress windows, handrail height, that kind of thing. It's built for long-term rental license inspections, not OSE short-term rental reviews specifically, so keep the two processes separate in your planning.

How to become a landlord in New York City (and what changes if you plan to short-term rent)

Becoming a landlord in NYC starts the same way it does anywhere: you either own property already or buy one, and you decide to rent out space you're not using yourself. There's no single 'landlord license' most owners need for standard long-term rentals in NYC the way some other cities require, but multiple dwellings (three or more units) generally need to be registered with HPD (the Department of Housing Preservation and Development), and owner-occupied buildings with certain unit counts have their own filing rules. What is landlording, in practical terms? It's managing a property you don't live in full-time (or a portion you rent out) for other people to live in, which comes with legal duties: keeping the unit habitable, handling repairs, following notice rules for entry, and following eviction procedures set by state and local law. A landlord, put simply, is the person or entity that owns rental property and is legally responsible for its condition and its compliance with housing law. If part of your plan is renting rooms or your unit short-term when you travel, the extra step is the OSE registration process outlined above, on top of any standard HPD registration your building already requires. Skipping HPD registration and skipping OSE registration are two separate violations with two separate enforcement tracks, so confirm both are current if you're doing any hosting.

What rights do tenants have without a lease, and how does that interact with subletting?

Tenants without a written lease (month-to-month tenants, in most states) still have real legal protections. In New York, that includes the right to a habitable unit, protection from illegal lockout or self-help eviction, and, in many cases, notice requirements before a landlord can end the tenancy, generally 30, 60, or 90 days depending on how long the tenant has lived there, under New York's Real Property Law §226-c ^[4]. This matters for short-term rental compliance because a tenant without a lease (or with a lease silent on subletting) is not automatically free to Airbnb their unit. New York's Multiple Dwelling Law and Local Law 18 registration requirements apply to tenants the same way they apply to owners, and most leases separately prohibit subletting without landlord consent regardless of what city law allows ^[3]. If you're a tenant thinking about short-term subletting, check your lease's sublet clause first, then confirm the building type and OSE registration requirement. Doing one without the other is how tenants end up facing both a lease violation from their landlord and a city fine at the same time.

Why do landlords require renters insurance, and does it matter for short-term rentals?

Landlords ask for renters insurance mainly to shift liability risk. If a tenant's negligence causes a fire, flood, or injury, renters insurance covers the tenant's liability and often the tenant's own belongings, reducing the odds the landlord's own policy has to absorb a claim or that the landlord ends up in a dispute over who pays for damaged property ^[5]. Many landlord insurance policies also specifically exclude or limit coverage for short-term rental activity, since renting out a unit for stays under 30 days is a different risk profile (more turnover, more strangers, more wear) than a standard year-long tenancy. If you're planning to short-term rent any part of your unit, call your insurance carrier before you list anything. Running an unregistered short-term rental is one problem; finding out your policy doesn't cover a guest's injury claim is a much more expensive one. Some carriers offer short-term rental or 'home-share' endorsements that add coverage for paying guests. These typically cost more than a standard renters or landlord policy and often require proof of OSE registration or equivalent local compliance before binding coverage, though exact terms vary by carrier.

How much notice does a landlord have to give before entering, and does OSE registration change that?

In New York, there's no single statewide statute spelling out an exact number of hours for routine landlord entry notice the way some states do, but New York City's Housing Maintenance Code and standard lease practice generally expect reasonable advance notice for non-emergency entry, commonly interpreted as 24 hours in practice, with emergency access allowed without notice for genuine safety issues like a gas leak or active flooding. OSE registration doesn't change a landlord's entry notice obligations to their own tenants. It's a separate compliance track entirely, dealing with the landlord's or host's relationship to the city and to booking platforms, not the landlord's relationship to a subtenant or co-tenant living in the unit. If you're a landlord who discovers a tenant is running an unregistered short-term rental, your entry rights to investigate are still governed by your lease and by state and city law on landlord entry, not by OSE's enforcement authority. You may need to document the sublet activity through legitimate means (mail, visible listings, complaints from neighbors) rather than assuming Local Law 18 gives you expanded inspection rights inside the tenant's unit.

What can a landlord look at during a standard rental inspection?

During a standard inspection tied to a rental license, HPD registration, or a housing code complaint, an inspector or landlord conducting a walk-through can generally check life-safety items: smoke and carbon monoxide detectors, means of egress, electrical hazards, plumbing leaks, structural issues, pest evidence, and whether the unit matches its certificate of occupancy. A landlord's own periodic walk-through (separate from a government inspection) is usually limited to what the lease allows and what state law permits regarding notice and purpose. Who's responsible for a rental property walk-through inspection varies by state and by whether it's a move-in/move-out inspection versus a code inspection. In many states, including California, the landlord (or their agent) is responsible for conducting and documenting move-in and move-out condition inspections, and California Civil Code §1950.5 specifically gives tenants the right to request a joint pre-move-out inspection with the landlord before the tenancy ends, so any needed repairs can be identified early ^[6]. That's a landlord-tenant condition inspection, though, not a city licensing inspection; each city with a rental license or registration program runs its own inspection process with its own scope, so confirm the specifics with your city rental licensing office. For NYC hosts specifically, OSE's enforcement checks are narrower: they're focused on verifying occupancy, presence, and registration status tied to short-term rental use, not general housing code compliance, which falls to HPD or DOB instead ^[1].

What can't a landlord do, and how do the rules differ by state (using Ohio as an example)?

Every state limits what a landlord can do, and the specifics vary, but common prohibitions include: no self-help eviction (changing locks or removing a tenant's belongings without a court order), no shutting off utilities to force a tenant out, no retaliating against a tenant for making a habitability complaint, and no discriminating based on protected classes under the federal Fair Housing Act. In Ohio specifically, landlords are barred from these actions under Ohio Revised Code §5321.02, which prohibits retaliatory conduct like decreasing services, raising rent, or filing eviction in response to a tenant reporting a code violation or exercising a legal right, and separately Ohio law prohibits landlords from using self-help methods (like lockouts) to remove a tenant instead of using the court eviction process . This matters even for out-of-state readers of a New York-focused article because the pattern repeats everywhere: local rules on registration and inspection (like Local Law 18) sit on top of a separate, usually stronger, layer of state landlord-tenant law governing eviction process, retaliation, and entry. Always check both layers, more than the local licensing rule that triggered your search.

Frequently asked questions

Do I need to register with OSE if I only rent a spare room, not my whole apartment?

Yes. Local Law 18 registration applies to any short-term rental (stays under 30 days) advertised on a booking platform, whether you're renting a spare room or the whole unit. Renting a room while you remain present actually fits the Multiple Dwelling Law's host-presence requirement better than a whole-unit rental does, but you still need to register ^[1][3].

How long does OSE take to approve a short-term rental registration?

There's no fixed statutory timeline, and processing times have varied since the portal launched, with some hosts reporting waits of several weeks. Don't book guests assuming approval before you actually have a registration number, since platforms are required to block unregistered listings ^[1][2].

Can Airbnb still list my NYC apartment if I'm not registered?

No, not legally. Local Law 18 requires booking platforms to verify a registration number before processing a short-term rental transaction for a New York City listing. Unregistered listings should be blocked from completing bookings on compliant platforms ^[2].

What's the fine for an unregistered short-term rental in NYC?

Civil penalties tied to illegal short-term rental activity under the Multiple Dwelling Law and Local Law 18 framework can reach up to $5,000 per violation, with amounts depending on the specific provision cited and whether it's a repeat violation ^[3][1].

How do I become a landlord if I already own an apartment I'm not living in?

You typically need to check whether your building requires HPD registration (common for buildings with three or more units), understand your notice and habitability obligations under New York law, and decide whether you'll self-manage or hire a property manager. There's no single citywide 'landlord license' for standard long-term rentals in NYC.

What is landlording as a business, exactly?

Landlording means owning and managing rental housing: collecting rent, maintaining habitability, handling repairs, following legal notice and eviction procedures, and complying with any local registration or licensing rules. It's a legal role with real obligations, more than passive income collection.

Who is responsible for a rental property walk-through inspection in California?

The landlord or their agent is generally responsible for conducting move-in and move-out inspections. California Civil Code §1950.5 gives tenants the right to request a joint inspection before move-out so repair issues can be addressed before the final deposit accounting ^[6].

What rights does a tenant have without a signed lease?

A tenant without a lease is usually a month-to-month tenant and still has habitability rights, protection from illegal lockout, and notice requirements before termination. In New York, required notice generally ranges from 30 to 90 days depending on tenancy length, under Real Property Law §226-c ^[4].

Why do landlords require renters insurance before move-in?

Mainly to shift liability. If a tenant's negligence causes damage or injury, renters insurance covers the tenant's liability and belongings, which reduces disputes over who pays and protects the landlord's own policy from absorbing preventable claims ^[5].

How much notice does a landlord need to give before entering a unit?

New York doesn't set one statewide number of hours for routine entry, but standard practice and NYC housing code norms generally expect at least 24 hours notice for non-emergency entry. Emergencies (active leaks, gas smells, fire risk) allow entry without advance notice.

What can't a landlord do in Ohio specifically?

Ohio landlords can't retaliate against tenants for reporting code violations (Ohio Revised Code §5321.02), can't use self-help methods like changing locks to force a tenant out instead of filing for eviction, and can't discriminate based on protected classes under federal fair housing law ^[7].

Does Local Law 18 apply to co-ops and condos, or just rentals?

It applies based on the type of building (Class A multiple dwelling) and the length of stay, not on whether units are owned as condos or co-ops versus rented. A condo owner hosting a short-term guest for under 30 days still needs OSE registration and must follow host-presence and guest-count rules if applicable ^[1][3].
