Short-term rental rules updates this week: Mountainside, Sydney, and France each moved on rules affecting short-term rental operators — one tightening pre-emptively, one investigating a suburb-level ban, and one bringing a long-planned national registration obligation into force.
Mountainside Borough Bans Short-Term Rentals Before FIFA World Cup Arrives
- Mountainside Borough Council in Union County, New Jersey introduced an ordinance that would ban all short-term rentals of 30 days or less within borough boundaries. The proposal continues to allow rentals longer than 30 days. The ordinance passed its first reading and is expected to return for a future public hearing.
- Violations would carry fines of up to $2,000 per day, including for advertising a prohibited rental online. Enforcement runs through the borough’s existing zoning violation procedures rather than a new dedicated regime.
- Council members cited the 2026 FIFA World Cup as the driver. The next Mountainside Council meeting is scheduled for May 19, 2026 — no final vote date has been set.
- Mountainside sits roughly 20 miles from MetLife Stadium in East Rutherford, NJ — one of the tournament’s primary US venues. Mountainside is not itself a FIFA host city; the borough’s move is preemptive rather than responsive to a specific projection.
Uvika’s Views
- Mountainside is not on FIFA’s host-city list, but it’s within a one-hour drive of MetLife Stadium and within commuter range of Manhattan, putting it in the spillover zone where fans search for accommodation when host-city inventory thins out. New York–New Jersey World Cup demand has been building since the December draw — occupancy was already running more than 20 times higher than the same point last year. Whether other suburban municipalities adjacent to host venues take similar action is the variable to watch.
- For property managers with inventory in any New Jersey town within roughly 30 miles of MetLife — particularly in Union, Essex, Bergen, and Hudson counties — Mountainside is the early indicator. Operators in this zone may want to check whether their own town council has a similar item on the agenda before deciding whether to onboard new properties for the tournament.
- The contrast with Hoboken, NJ is sharp. Hoboken — within sight of Manhattan — has remained essentially laissez-faire, and listings there have surged as operators position for tournament demand. Same state, similar proximity to a host venue, two opposite responses. The takeaway for PMs is that New Jersey regulatory exposure currently varies block-by-block, not state-by-state.
- Mountainside acting unilaterally could put pressure on Union County to coordinate a county-level framework, particularly if Hoboken-style surges develop in nearby Springfield, Berkeley Heights, or Westfield. Whether the borough’s neighbours follow Mountainside’s lead is the next data point.

MetLife Stadium — A primary venue for the 2026 FIFA World Cup, hosting eight matches including the final on July 19, 2026. The stadium sits in East Rutherford, Bergen County, NJ — roughly 30 minutes north of Mountainside. Its location adjacent to the New York metropolitan area makes the surrounding suburban zone one of the highest-demand accommodation markets during the tournament.
Sydney Council Backs Investigation of Suburb-Level Short-Term Rental Bans
- The City of Sydney Council passed a motion in late April — on Tuesday, April 28, 2026 — directing the Chief Executive Officer to investigate new restrictions on short-term rental accommodation, including a possible suburb-level ban. Moved by Councillor Matthew Thompson and seconded by Councillor Jess Miller, the motion originated from Greens Councillor Sylvie Ellsmore and was carried with cross-bench support.
- The investigation scope names 11 inner-Sydney suburbs as candidates for a potential ban: Millers Point, The Rocks, Darlinghurst, Woolloomooloo, Ultimo, Haymarket, Kings Cross, Surry Hills, Potts Point, Chippendale, and Pyrmont — with “but not limited to” language allowing other areas to be added.
- The trigger mechanism under consideration: a ban would activate when a suburb’s rental vacancy rate falls below 3 percent. Per SQM Research data, the City of Sydney’s vacancy rate sat at 1.1 percent in March 2026, down from 1.3 percent in February. Several individual suburbs in scope are already well under 2 percent.
- The ban would apply only to non-primary-residence properties — homes used as the owner’s primary residence would remain exempt, consistent with the framing the City has applied to STR policy since 2023.
- Context on the existing framework: NSW state law caps non-hosted Short Term Rental Accommodation (STRA) — the official planning category for short-term rental of residential property to paying guests — at 180 days per year in Greater Sydney. The City’s own analysis identified 5,454 active STRA properties in the LGA versus 2,468 officially registered — a gap the council has cited as evidence the state framework is not being adequately enforced.
- Stayz responded that existing state regulations are sufficient and additional local restrictions would create unnecessary complexity for owners and visitors. Airbnb said short-term rentals are an important part of the tourism economy.
Uvika’s Views
- This is an investigation, not a ban yet. The motion instructs the CEO to study restrictions and report back to council; it does not implement a ban now. Several news headlines have blurred this distinction. Property managers in the 11 named suburbs have a reporting cycle to watch — likely a council report later this year — before anything materially changes on the ground.
- The Sydney story connects directly to a strategic question RSU flagged in May about Airbnb’s hotel push: Airbnb’s open job postings include a Senior Market Manager, Hotels role in Sydney, alongside similar roles in Tokyo and Singapore. A Sydney STR ban that pulls non-primary-residence properties out of the home market in 11 tourist-dense suburbs would create exactly the supply gap Brian Chesky described on the Q1 earnings call as the strategic case for hotels on the platform. Whether or not Sydney appears explicitly in the May 20 Summer Release, the underlying logic of Airbnb’s hotel pivot just got sharper.
- The vacancy-rate trigger is the operationally interesting design choice. Tying a ban to a 3 percent threshold means the rule would activate automatically based on market data, rather than requiring a separate council vote each cycle. Vacancy-rate triggers are increasingly common in housing-affordability legislation globally, but rarely seen in STR rules specifically. Whether this design survives the investigation phase is worth watching.
- The Byron Bay precedent sits behind this. The NSW Independent Planning Commission has already endorsed Byron Shire’s tighter 60-day cap on non-hosted STRA as a housing-affordability measure. Sydney’s investigation builds on that precedent. Notably, recent University of Sydney research presented at a Byron Council event on May 8 found the existing 180-day and 60-day NSW caps have not reduced Airbnb’s market share in coastal NSW towns — the empirical case for caps as a housing tool is contested even as the political appetite for them grows.

Short Term Rental Accommodation (STRA) — The official NSW Planning category covering all short-term rental of residential properties to paying guests. The current state framework caps non-hosted STRA (where the owner is not present) at 180 days per year in Greater Sydney; hosted STRA (owner on premises) is unlimited. Local councils have limited authority to deviate unilaterally; the NSW Independent Planning Commission can endorse council-level variations where housing affordability is at stake — as it did for Byron Shire’s 60-day cap.
City of Sydney LGA (Local Government Area) — The local government covering Sydney’s CBD and inner suburbs, with approximately 230,000 residents. Distinct from “Greater Sydney” (the broader metropolitan area, governed by multiple councils). Decisions in the City of Sydney LGA apply only to the suburbs within its boundaries, which include all 11 areas named in the current investigation.
France’s Declaloc Registration Obligation Activates in 9 Days — but the Portal Is Delayed
- France’s loi Le Meur — the country’s 2024 short-term rental regulation law (Law No. 2024-1039 of November 19, 2024), informally called the “anti-Airbnb law” after its lead sponsors Annaïg Le Meur and Iñaki Echaniz — activates a national registration obligation on May 20, 2026. The portal is named Declaloc, finalised by decree 2026-196 of March 19, 2026.
- Important correction from what has been widely reported: May 20 is when the legal obligation activates — not when the Declaloc portal goes live. The Direction générale des entreprises (DGE) has announced that the final landlord-facing version of the portal will not be fully operational until the second half of 2026. Hosts in communes with existing local registration systems (Paris, Lyon, Bordeaux, Marseille, Nice, and others) should continue registering through those channels. Existing local registration numbers remain valid during the transition to the national system.
- From May 20, every meublé de tourisme — the French legal category for tourist-furnished rentals — must hold a Declaloc registration number, including properties that have operated for years under local-only registration regimes. Once issued, the number must appear on all listings across all platforms.
- Penalties under Article 4 of the law: fines of up to €10,000 for failure to register on the national portal, and up to €20,000 for false declaration or use of a fraudulent registration number.
- The law gives mayors expanded enforcement powers — including the authority to lower the national 120-day annual cap for primary-residence rentals to as low as 90 days by council resolution, and to apply stricter STR rules in housing-pressure zones. Separately, co-owners in apartment buildings can now vote to prohibit STR activity in their own building by a two-thirds majority under specific conditions — a power given directly to building residents, not to mayors.
- May 20 is the same date as the EU Regulation 2024/1028 Single Digital Entry Point deadline that applies across all 27 member states. The two systems are coordinated but technically distinct — France’s Declaloc is the domestic single-portal implementation; the EU regulation governs platform-level data sharing between hosts, platforms, and member-state authorities.
Uvika’s Views
- This is operationally the highest-urgency story of the week for any property manager with French inventory — but the practical picture is more nuanced than the May 20 deadline suggests. The legal obligation to hold a registration number activates May 20. The Declaloc portal itself is delayed to Q4 2026. That means hosts in communes with existing local registration systems should verify their current numbers are in place; those in communes that had no local registration requirement are in a more uncertain position and should monitor official DGE communications closely.
- The fines structure is worth reading carefully. The €10,000 ceiling applies to missing registration — a procedural failure. The €20,000 ceiling applies to false declaration or false registration number — a substantive misrepresentation. The doubling matters because it telegraphs how French enforcement may prioritise: false-information cases are typically easier to prove than missing-registration cases and politically simpler to pursue first. Paris has already issued close to €1 million in fines in Q1 2026 alone, and nine other major French cities operate under the same national framework.
- For PMs running portfolios across multiple French markets — Paris, Nice, Lyon, Bordeaux, Marseille — the mayor’s expanded powers are the longer-term consequence. The national registration creates a single dataset that mayors can query for enforcement; in housing-pressure cities, that dataset becomes the input for tighter local rules in the months following the deadline.
- The interaction with the EU SDEP regulation is worth tracking. Both obligations activate on the same day, both apply to the same properties, both require platforms to coordinate. The portal delay on the Declaloc side may create operational uncertainty for hosts in the early weeks — particularly in communes where there is no existing local registration channel to fall back on.

Loi Le Meur — France’s law strengthening local tools for regulating tourist rentals (Law No. 2024-1039 of November 19, 2024). Tightens fiscal alignment between tourist rentals and long-term residential rentals, requires energy-performance certificates (DPE — Diagnostic de Performance Énergétique) for tourist rentals, and creates the national Declaloc registration system whose legal obligation activates May 20, 2026 — though the portal itself is delayed to Q4 2026.
Declaloc — France’s national single-portal registration system for meublés de tourisme, mandated by loi Le Meur and finalised by decree 2026-196 of March 19, 2026. Replaces the patchwork of local-only registration systems with a centralised database that mayors and the national government can query for enforcement purposes. The DGE has confirmed the final landlord-facing portal will not be fully operational until the second half of 2026; existing local registration numbers remain valid during the transition.
