NYC Local Law 18: short-term rental registration guide

Last updated 2026-07-26

What is NYC Local Law 18 and why does it matter for short-term rentals?

Local Law 18 of 2022 is New York City's short-term rental registration law. It took effect for enforcement purposes on September 5, 2023, after a phase-in period, and it requires anyone hosting paid stays of less than 30 days to register with the Mayor's Office of Special Enforcement (OSE) before listing or booking a unit ^[1]. The law didn't invent short-term rental restrictions in New York. State law (the Multiple Dwelling Law, often called the "three-guest law") already barred whole-unit rentals under 30 days in most Class A multiple dwellings unless a permanent resident stays on site ^[2]. Local Law 18 layered a registration and enforcement system on top of that existing restriction, and it forced booking platforms like Airbnb and Vrbo to verify registration numbers before processing NYC bookings. The practical effect has been dramatic. OSE's own reporting and independent tracking after the law took effect showed active short-term listings on major platforms drop sharply, with many hosts either registering, switching to 30-plus-day rentals, or pulling listings entirely ^[1]. If you're a small landlord who rented out a spare room or an accessory unit on Airbnb before 2023, this law is almost certainly why your old listing strategy stopped working.

Who needs to register under Local Law 18?

You need to register if you host, or plan to host, paid occupancy of fewer than 30 consecutive days in a dwelling unit within the five boroughs, and you (or a permanent resident of the unit) will be present during the stay ^[1]. This covers homeowners renting a spare bedroom, co-op or condo owners hosting occasional guests, and landlords who live in one unit of a small multifamily building and want to rent out a room short-term. It generally does not cover traditional long-term tenancies of 30 days or more, hotels, or class B multiple dwellings that already operate under different rules. It also doesn't apply if you're renting the entire apartment while you're away, because OSE requires a host or permanent resident present for the duration of the stay in most residential buildings covered by the law ^[1]. If you're unsure whether your unit qualifies, check your building's certificate of occupancy and confirm with your city rental licensing office or OSE directly, because building class and permanent resident status drive the answer more than anything else.

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

Registration happens through OSE's online portal. You'll need to create an account, provide identifying information about yourself and the unit, attest that you meet the requirements (permanent residency in the unit, compliance with building and fire codes, no more than two paying guests at a time), and submit the application for review ^[1]. OSE reviews each application and either approves it, issues a registration number, or denies it with a stated reason. Processing times have varied since launch; some hosts report approvals in a few weeks, others report longer waits, especially early in the program when application volume was high. Confirm current processing timelines with OSE's registration page directly, since this has changed as the backlog has cleared. Once approved, your registration number must be included on every listing you post on a booking platform. Platforms are legally required to verify that number against OSE's registry before allowing a listing to go live or a booking to be completed ^[1]. If your registration lapses, gets revoked, or was never issued, platforms are supposed to block the listing.

What are the actual rules once you're registered?

Registration isn't just a formality. It comes with operating conditions that OSE and the city can enforce. You or a permanent resident of the household must be present in the unit for the entire stay. You cannot rent out the whole apartment while you travel and call it compliant, that's the core distinction from the pre-2023 short-term rental market ^[1]. No more than two paying guests may occupy the unit at a time, consistent with the underlying Multiple Dwelling Law restriction on unrelated occupants in these arrangements ^[2]. Internal doors within the unit cannot be locked to separate guests from the host or other household members. This rule exists because the whole legal theory behind allowing short-term stays in a Class A building rests on the unit still functioning as one household's home, not a partitioned mini-hotel. You must keep your registration current and display your registration number accurately on every platform listing. A registration number is unit-specific and host-specific; you can't borrow someone else's or reuse an old one for a different apartment.

What happens if you don't register or you break the rules?

Penalties under Local Law 18 are real money, not a slap on the wrist. Violations can run up to $2,500 for a first offense and higher for repeat violations, with penalty structures set out in the local law and enforced by OSE alongside the Department of Buildings and other agencies with jurisdiction over illegal occupancy ^[1]. Booking platforms face their own penalties (up to $1,500 per violation in some structures) for processing transactions tied to unregistered units, which is exactly why Airbnb and similar platforms now block unregistered NYC listings outright rather than risk it ^[1]. Beyond OSE penalties, an unregistered short-term rental that violates the underlying Multiple Dwelling Law occupancy restriction can also draw a Department of Buildings violation for illegal occupancy, which carries its own fine schedule and can complicate a sale or refinance down the road ^[2]. Stacking a Local Law 18 violation on top of a DOB violation is a genuinely bad outcome for a small landlord, since it turns a one-time fine into a paper trail that shows up in title searches.

How does Local Law 18 relate to New York's Multiple Dwelling Law?

Local Law 18 is a city registration and enforcement scheme. The underlying legal restriction on short stays comes from state law, specifically New York's Multiple Dwelling Law Section 4(8), which defines what counts as a legal "permanent resident" occupancy versus a transient one in Class A buildings ^[2]. That state law is why whole-unit short-term rentals under 30 days have been restricted in most NYC apartment buildings since well before Local Law 18 existed. The city law didn't loosen or tighten that underlying restriction; it built a registration and platform-verification system to actually enforce it, since prior enforcement relied mostly on complaint-driven inspections that were slow and inconsistent. If you own a two-family or three-family home that isn't a Class A multiple dwelling, different rules may apply, and this is exactly the kind of building-class question worth confirming with your city rental licensing office or a local land use attorney before you list anything.

Does Local Law 18 apply to landlords renting to long-term tenants?

No. If your lease term is 30 days or longer, Local Law 18's registration requirement doesn't apply to that tenancy at all ^[1]. This law targets the short-term, hotel-like rental market, not standard month-to-month or annual leases. That said, plenty of landlords who normally run traditional long-term rentals also dabble in short-term hosting between tenants, during renovations, or in an owner-occupied unit. If that's you, the moment you list a stay under 30 days for pay, you're inside Local Law 18's scope for that listing, even if 95 percent of your business is long-term leasing. If you're building out a broader landlord operation that includes both long-term units and occasional short-term hosting, it's worth reading up on tenant rights and tenants rights generally, since your obligations differ meaningfully between a Local Law 18 short-term guest and a standard leaseholder.

How do you become a landlord in NYC, and what does landlording actually involve?

Becoming a landlord starts well before your first tenant moves in. At a minimum you need a legally habitable unit (proper certificate of occupancy, working smoke and carbon monoxide detectors, no open hazardous violations), a lease that complies with New York's rent stabilization and habitability rules where applicable, and a plan for handling repairs, rent collection, and turnover. "Landlording" is the ongoing work of running rental property: screening tenants, collecting rent, handling maintenance requests, managing move-in and move-out inspections, keeping insurance current, and staying compliant with city and state housing codes. A landlord, simply put, is the owner (or their authorized agent) who leases real property to a tenant in exchange for rent and who remains legally responsible for keeping that property habitable. Many first-time landlords underestimate how much of the job is paperwork and compliance rather than tenant relations. Building violations, registration lapses, and missed inspection windows cause more financial pain for small landlords than difficult tenants do, in our experience covering these programs city by city. If you're starting from zero, landlord landlords and landlord cover the foundational registration and compliance steps most cities require before you can legally rent at all.

What rights do tenants have without a signed lease, and how much notice is required to end a tenancy?

A tenant without a written lease still has real legal protections in New York; an oral or month-to-month tenancy is still a tenancy, and the tenant is entitled to habitable conditions, protection from illegal lockout, and proper notice before eviction or non-renewal. Notice requirements in New York scale with how long the tenant has lived there. Under New York Real Property Law Section 226-c, a landlord who wants to raise rent by 5 percent or more, or who doesn't intend to renew a lease, must give 30 days' notice for tenancies under one year, 60 days' notice for tenancies between one and two years, and 90 days' notice for tenancies of two years or more ^[3]. Those notice periods apply regardless of whether the original agreement was written or oral, which surprises a lot of first-time landlords who assume a handshake lease means no rules apply. If you're managing a unit without a formal lease, read up on tenant and tenant rights and renters rights before you send any notice, since getting the timeline wrong can void the notice entirely and restart your clock.

Why do landlords require renters insurance, and what should the lease say about it?

Landlords require renters insurance mainly to shift liability risk away from the building owner's policy. A landlord's own property insurance covers the structure and the landlord's assets; it typically does not cover a tenant's personal belongings or the tenant's personal liability if they cause a fire, flood, or injury to a guest. Requiring renters insurance, usually with a modest liability minimum like $100,000, gives the landlord a second layer of protection: if a tenant's negligence causes damage, the tenant's own policy often pays first, reducing claims against the landlord's coverage and keeping premiums lower over time. It's not a legal requirement in most cities the way registration or licensing is, but it's become close to standard practice in professionally managed buildings. We're not a law firm and this isn't legal advice, but as a practical matter, if you're going to require renters insurance, put the requirement and the minimum coverage amount directly in the lease, and ask for a certificate of insurance naming you as an interested party so you actually know coverage is active, more than promised.

What can a landlord look at during a rental inspection, and who's responsible for it?

Inspection scope depends heavily on the city and the type of inspection (move-in/move-out walkthrough versus a mandatory rental licensing inspection). In cities with mandatory rental inspection programs, code enforcement officers generally check smoke and carbon monoxide detector function, egress windows, electrical panel condition, plumbing leaks, pest evidence, and general structural safety, not a tenant's personal belongings or lifestyle. For routine move-in and move-out walkthroughs (as distinct from government licensing inspections), responsibility for conducting and documenting the inspection typically falls to the landlord or property manager, though many states require the landlord to offer the tenant a chance to participate and sign off on the condition report before any security deposit deductions are made. In California specifically, Civil Code Section 1950.5 gives tenants the right to request an initial move-out inspection before vacating, so they can fix issues themselves and avoid deposit deductions, and the landlord must give at least 48 hours' written notice before conducting that inspection ^[4]. A landlord conducting a mandatory city licensing inspection (the kind tied to a rental registration program) usually cannot search personal belongings, closets full of clothes, or private papers; the inspection is limited to conditions affecting habitability and code compliance. If a notice for this kind of inspection just landed in your mailbox, it helps to walk your own unit first and fix anything a code officer would flag on sight, like a missing smoke detector cover or a blocked emergency exit.

What can't a landlord do in Ohio, and how does that compare to New York?

Ohio's landlord-tenant law, codified at Ohio Revised Code Chapter 5321, prohibits several things landlords in other states sometimes get away with. A landlord cannot shut off utilities, change the locks, or remove a tenant's belongings to force them out without going through the formal eviction process in court; that's illegal self-help eviction, and Ohio courts treat it seriously ^[5]. Ohio landlords also cannot retaliate against a tenant for reporting a code violation or joining a tenant organization, and they're required to maintain the premises in a fit and habitable condition under R.C. 5321.04, covering things like functioning plumbing, heat, and structural safety ^[5]. Compare that to New York, where similar self-help eviction bans exist and where warranty of habitability protections are arguably even broader given the density of multiple dwelling law and local housing code layered on top of state law. The specifics differ by state, but the core principle is consistent nationally: a landlord anywhere in the U.S. generally cannot lock out a tenant, seize belongings, or cut utilities to force a move without a court order.

How does a $79 packet help with Local Law 18 or other city rental compliance?

None of this is legal advice, and every city's rental licensing and short-term rental program has its own quirks, forms, and fee schedules that change over time. What tends to trip up small landlords isn't the concept, it's the paperwork logistics: knowing which forms your specific city or program requires, what documentation an inspector or OSE reviewer will actually ask for, and how to organize it before a deadline instead of scrambling after a violation notice arrives. That's the gap our $79 one-time City Rental License & Inspection Prep Packet is built to close. It's not a substitute for reading your city's actual ordinance or OSE's registration guidance directly, but it gives you an organized starting point, a checklist built around what registration and inspection programs commonly require, so you're not starting from a blank page after your first violation notice shows up. If you want a structured way to prep before you register or before an inspector shows up, the rental packet builder walks through it step by step.

Frequently asked questions

Do I need to register with OSE if I only rent my apartment while I'm on vacation?

No, and in most cases you legally can't. Local Law 18 requires the host or a permanent resident to be present for the entire stay, so whole-unit rentals while you're traveling generally aren't eligible for registration in Class A multiple dwellings. That kind of rental was already restricted under New York's Multiple Dwelling Law before Local Law 18 existed.

How much does Local Law 18 registration cost?

OSE's registration process itself doesn't carry a listed application fee as of the law's rollout, but confirm current costs directly with OSE's registration portal since city fee schedules change. The real cost risk is the penalty side: violations can run up to $2,500 or more per offense if you host without a valid registration.

Can I still rent out a room in my apartment on Airbnb in NYC?

Yes, if you register with OSE first, remain present in the unit during the stay, host no more than two paying guests, and don't lock interior doors to separate yourself from guests. This is exactly the scenario Local Law 18 was built to allow, distinct from whole-apartment rentals while the host is away.

What building types are exempt from Local Law 18?

The law applies primarily to Class A multiple dwellings, which is most NYC apartment buildings. Hotels, Class B multiple dwellings, and certain smaller buildings may fall under different rules. Check your building's certificate of occupancy and confirm your building class with your city rental licensing office before assuming you're exempt.

How to become a landlord if I've never rented out property before?

Start by confirming your unit is legally habitable and properly classified, then check whether your city requires rental registration or licensing before you can lease it out. Draft a compliant lease, secure landlord insurance, and set up systems for rent collection and maintenance requests before you list the unit, not after.

What is landlording as a day-to-day job?

Landlording is the ongoing work of owning and operating rental property: screening tenants, collecting rent, responding to repair requests, handling move-in and move-out inspections, keeping required licenses and registrations current, and staying compliant with local housing codes. It's more compliance and maintenance work than most first-timers expect.

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

The landlord is generally responsible for conducting the inspection, but California Civil Code Section 1950.5 gives tenants the right to request an initial inspection before move-out, with at least 48 hours' written notice, so they can fix deficiencies themselves and avoid losing part of their security deposit.

What rights do tenants have without a signed lease in New York?

A tenant without a written lease is still legally a tenant, generally on a month-to-month basis, and retains rights to habitable conditions and protection from illegal lockout. Under New York Real Property Law Section 226-c, notice periods before rent increases or non-renewal still apply based on how long the tenant has occupied the unit.

Why do landlords require renters insurance if it's not legally mandatory?

Renters insurance shifts liability for a tenant's belongings and personal liability away from the landlord's own policy. If a tenant causes damage or an injury occurs in their unit, their policy typically pays first, which reduces claims against the landlord's coverage and helps keep the landlord's premiums stable.

How much notice does a landlord have to give before ending a tenancy in New York?

Under New York Real Property Law Section 226-c, landlords must give 30 days' notice for tenancies under one year, 60 days' for tenancies between one and two years, and 90 days' for tenancies of two years or more, when raising rent 5 percent or more or not renewing a lease.

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

Mandatory city rental inspections typically focus on smoke and carbon monoxide detectors, electrical and plumbing systems, structural safety, egress windows, and pest conditions. Inspectors generally aren't authorized to search personal belongings or private papers; the inspection is limited to habitability and code compliance issues.

What can't a landlord do in Ohio under state law?

Under Ohio Revised Code Chapter 5321, a landlord cannot shut off utilities, change locks, or remove a tenant's belongings to force them out without a court-ordered eviction. Landlords also cannot retaliate against tenants for reporting code violations and must maintain the unit in fit, habitable condition under R.C. 5321.04.

What happens if a booking platform lists my NYC apartment without my Local Law 18 registration number?

Booking platforms are required to verify a valid OSE registration number before processing a short-term booking in NYC. Platforms that process bookings for unregistered units face their own penalties, which is why Airbnb and similar sites now block listings that lack a verified registration number.
