The administration of Mayor Eric Adams, through the Office of Special Enforcement (OSE), has officially acknowledged that Airbnb is adhering to the technical verification requirements established under New York City’s rigorous short-term rental registration law, known as Local Law 18. However, despite this technical compliance, city officials are signaling that the platform could—and should—take more proactive measures to prevent the conversion of verified legal listings into illegal operations. This stance comes as the city intensifies its crackdown on "shadow hotels" and illegal rental networks that officials argue exacerbate the city’s chronic housing shortage.
Christian Klossner, the Executive Director of the Office of Special Enforcement, clarified the city’s position in a recent statement, noting that while Airbnb is meeting its legal obligations under the current framework, there remains a gap between regulatory compliance and the platform’s potential to curb illicit activity. According to Klossner, Airbnb complies with the verification requirements of Local Law 18, but the company could further support New York City hosts and residents by preventing verified legal listings from being surreptitiously changed to offer illegal stays. He noted that while such preventative measures would be beneficial for the city’s housing integrity, nothing in the existing legislative language mandates that Airbnb implement these specific technological safeguards.
The timing of these remarks coincides with a high-profile lawsuit filed by the city against a landlord and several associates who allegedly operated a sophisticated network of illegal short-term rentals across three residential buildings. This enforcement action serves as a poignant reminder of the challenges the city faces in policing a market that has largely moved underground or into the "gray market" following the implementation of strict registration protocols in late 2023.
The Regulatory Framework: Understanding Local Law 18
Local Law 18, also referred to as the Short-Term Rental Registration Act, was designed to bring transparency and order to a sector that city officials argued had spiraled out of control. Passed in January 2022 and entering full enforcement in September 2023, the law requires short-term rental hosts to register with the OSE. To receive a registration number, hosts must meet several stringent criteria: they must be the permanent resident of the unit being rented, they must be present during the guest’s stay, and they cannot host more than two guests at a time. Furthermore, the law mandates that the entire unit cannot be rented out; the host must share the living space with the guests.
For platforms like Airbnb, VRBO, and Booking.com, the law imposes a "verification" burden. These platforms are prohibited from processing transactions for listings that do not have a valid, city-issued registration number. The OSE maintains a database that platforms must check before a listing can go live or accept payments. Klossner’s confirmation that Airbnb is complying with these checks suggests that the automated systems between the city and the platform are functioning as intended. However, the "bait-and-switch" tactic—where a host registers a legal shared-room listing but then advertises or provides an illegal "entire home" stay after the initial verification—remains a point of contention.
Chronology of Enforcement and Legal Challenges
The path to the current regulatory environment has been marked by years of litigation and political maneuvering. The tension between New York City and Airbnb dates back over a decade, but the timeline leading to the current situation is particularly dense:
- January 2022: New York City Council passes Local Law 18 to curb the proliferation of illegal hotels.
- June 2023: Airbnb files a lawsuit against New York City, labeling the new regulations a "de facto ban" on its business model. The company argued that the requirements were overly burdensome and designed to eliminate short-term rentals entirely.
- August 2023: A New York state judge dismisses Airbnb’s lawsuit, clearing the way for the city to begin enforcement. The court ruled that the regulations were a reasonable exercise of the city’s power to manage housing and safety.
- September 5, 2023: Full enforcement of Local Law 18 begins. Thousands of unverified listings are removed from major platforms overnight.
- Early 2024: The OSE begins a series of targeted enforcement actions against large-scale illegal operators, moving beyond individual hosts to target landlords and property managers.
- Mid-2024: City officials acknowledge platform compliance but call for "voluntary" measures to close loopholes related to listing modifications.
Data Analysis: The Impact on Listings and the Housing Market
The implementation of Local Law 18 has had a profound impact on the landscape of short-term rentals in the five boroughs. Data from third-party analytics firms like AirDNA and Inside Airbnb reveal a dramatic shift in the market.
Prior to the enforcement of the law in August 2023, there were approximately 38,000 active Airbnb listings in New York City. By late 2023, that number had plummeted. Current estimates suggest that only a fraction of those listings remain as "legal" short-term rentals. As of early 2024, the OSE had received thousands of applications for registration, but the approval process remains rigorous. Hundreds of applications have been denied due to the units being located in buildings on the "Prohibited Buildings List"—a list of addresses where landlords have explicitly banned short-term rentals.
The reduction in short-term inventory has had a dual effect. On one hand, hotel industry data suggests a significant uptick in demand and pricing for traditional lodging. According to data from STR, the average daily rate (ADR) for New York City hotels saw a double-digit percentage increase in the months following the enforcement of Local Law 18, as travelers who previously relied on Airbnbs were funneled back into the hotel market.
On the other hand, the impact on the long-term rental market remains a subject of intense debate. Proponents of the law, including housing advocacy groups, argue that the return of thousands of units to the long-term market is essential for cooling the city’s record-high rents. Critics and host advocates, however, argue that many of these units were never destined for the long-term market, as they are located in owner-occupied homes where the owner has no intention of taking on a full-time tenant.
Targeted Enforcement: The Case Against Illegal Operators
While Airbnb handles the digital verification of registration numbers, the physical enforcement falls to the OSE. The recent lawsuit mentioned by Klossner highlights the city’s strategy of targeting high-volume offenders. In this specific case, a landlord and a group of associates were accused of transforming residential apartments in three separate buildings into a coordinated network of illegal short-term rentals.
The lawsuit alleges that the defendants used multiple accounts and deceptive listing practices to bypass city regulations. This "professionalization" of illegal rentals is what the OSE is most concerned about. These operations often remove entire rent-stabilized units from the market, replacing long-term residents with a revolving door of tourists. The city is seeking significant monetary penalties and permanent injunctions to prevent these individuals from operating in the future.
This enforcement action underscores the "loophole" Klossner referenced: the ability for sophisticated actors to manipulate the platforms even when the platforms are technically following the verification laws. By creating multiple listings or altering listing descriptions after a registration number has been verified, bad actors can continue to operate under the radar of automated systems.
Official Responses and Stakeholder Perspectives
The discourse surrounding short-term rentals in New York City is polarized, with each stakeholder group presenting a different vision for the city’s future.
The Office of Special Enforcement: The OSE maintains that its primary mission is safety and housing preservation. "Our goal is to ensure that residential housing remains available for New Yorkers and that any short-term rental activity is done safely and legally," Klossner has stated in various forums. The office views Local Law 18 as a vital tool in identifying and dismantling illegal hotel operations that threaten the character of residential neighborhoods.
Airbnb: For its part, Airbnb has shifted its tone from litigation to a degree of cautious cooperation, though the company remains critical of the law’s severity. In public statements, Airbnb representatives have emphasized their commitment to following the law while expressing concern that the regulations hurt everyday New Yorkers who relied on the extra income from hosting to afford their own rising housing costs. The company has not yet committed to the additional "voluntary" safeguards requested by the OSE, likely due to the technical complexity and potential liability involved in monitoring every change to a host’s listing in real-time.
The Hotel Industry: Trade groups such as the Hotel Association of New York City have been vocal supporters of the city’s crackdown. They argue that Airbnb and similar platforms enjoyed an unfair competitive advantage for years by operating outside the safety, tax, and labor regulations that govern the hotel industry. For them, Local Law 18 represents a leveling of the playing field.
Host Advocacy Groups: Organizations like "Restore Homeowner Autonomy and Rights" (RHOAR) represent the interests of small-scale hosts. They argue that the law is overly broad and unfairly punishes homeowners who are simply trying to make ends meet. They have called for amendments to the law that would distinguish between "mom-and-pop" hosts and large-scale commercial operators.
Broader Impact and Global Implications
The situation in New York City is being watched closely by urban planners and regulators worldwide. As one of the world’s most popular tourist destinations and one of its most expensive housing markets, NYC serves as a laboratory for short-term rental policy.
Other global cities, including London, Barcelona, and Paris, have implemented their own versions of registration schemes and stay limits. However, New York’s requirement for the host to be physically present is among the strictest in the world. If New York successfully proves that these regulations can return units to the long-term housing market without crippling the tourism economy, other cities may follow suit with similarly aggressive measures.
Furthermore, the "verification" model—where the platform shares the burden of enforcement—is becoming the gold standard for regulators. The European Union is currently moving toward a bloc-wide regulation that would require platforms to share data with local authorities, mirroring the cooperation now seen between Airbnb and the NYC OSE.
The "Shadow Market" and Future Challenges
As the city closes the door on illegal listings on major platforms, a new challenge has emerged: the migration of these listings to less-regulated corners of the internet. There are growing reports of short-term rentals being advertised on Craigslist, Facebook Marketplace, and specialized "underground" sites that do not have verification agreements with the city.
This "shadow market" is significantly harder to police. Unlike Airbnb, which provides a centralized point of contact and a digital paper trail, these peer-to-peer platforms often lack the infrastructure to verify registration numbers or facilitate tax collection. The OSE will likely need to expand its digital forensics capabilities to track these listings and identify the operators behind them.
The evolution of the Mamdani administration’s approach suggests that while the first phase of the crackdown—securing platform compliance—is largely complete, the second phase will involve a more granular and aggressive pursuit of those who attempt to circumvent the spirit of the law. The call for Airbnb to do more to prevent listing modifications is a clear signal that the city expects the private sector to be an active partner in enforcement, rather than just a passive observer of the law.
As the legal battles continue and the data matures, the true efficacy of Local Law 18 will become clearer. For now, the city remains steadfast in its belief that the path to a more affordable New York involves a highly regulated, and significantly smaller, short-term rental market. The tension between the ease of global travel platforms and the local necessity of housing stability remains the defining conflict of the modern urban economy.
