The Airbnb ban
won't fix
Barcelona.

The story writes itself — and that's the problem.

Barcelona. Rent up 62% in a decade. Protest signs reading "Tourist Go Home." Thousands of apartments locked behind tourist licences while locals are priced out of their own neighbourhoods. Mayor Collboni's announcement in June 2024 felt like justice: by 2028, all 10,101 short-term rental licences expire. No renewals. No exceptions.

Spain's Constitutional Court upheld it in March 2025. The hotel industry exhaled. Housing advocates cheered. International headlines followed. The narrative was clean: Airbnb causes housing crisis; remove Airbnb; crisis ends.

The problem with clean narratives is what they leave out.

Seven percent of housing stock is not trivial. But it is not the whole story either. Rents in Barcelona were already rising sharply before Airbnb reached meaningful scale in the city — driven by a decade of under-construction, mortgage lending changes, and surging demand from digital nomads and remote workers. Identifying which of these forces is doing how much work is not simple. The policy, however, is.

Correlation is not a housing policy.

The link between STR density and rising rents exists in the research — but it is weaker and more conditional than the political rhetoric suggests.

Wachsmuth & Weisler (2018) found a meaningful relationship between Airbnb penetration and rent increases in New York. Other studies in Barcelona confirm the correlation. But correlation is doing heavy lifting when it's used to justify an outright ban.

Consider the counterfactual cities. Vienna has Europe's most regulated short-term rental market — and one of its most stable housing markets. But Vienna also has 60% social housing, strict rent controls, and decades of active municipal construction. Tokyo has essentially no short-term rental market to speak of, and a housing crisis driven entirely by land-use restrictions. Berlin banned STRs entirely in 2016, then reversed course two years later after housing prices continued rising anyway.

The pattern is consistent: where housing supply is constrained by zoning, permitting, and construction inactivity, STR removal does not produce meaningful rent relief. STRs can exacerbate a supply shortage; they rarely cause it.

The cities with the highest STR penetration are not uniformly the cities with the worst rent growth. Tokyo, Singapore, and Zurich have severe housing affordability problems and negligible short-term rental markets. The causal arrow is more complicated than the ban implies.

Where do the tourists go?

Banning short-term rentals does not reduce demand for accommodation. It redirects it — overwhelmingly back into the hotel sector.

This is not a theoretical concern. It is what happened in New York. When Local Law 18 reduced Airbnb listings by over 90% in September 2023, hotel occupancy in Manhattan surged. By July 2024, hotel rates in the city were up 7% year-on-year. The hotel sector captured the demand that had previously been distributed across residential neighbourhoods. That demand didn't disappear — it concentrated.

In city terms, this matters. Short-term rentals distribute visitors into diverse neighbourhoods — Gràcia, Poblenou, Sarrià in Barcelona — spreading spending across local bakeries, markets, restaurants, and transit. Hotel zones, by contrast, concentrate visitors. La Barceloneta fills further. The Gothic Quarter thickens. The places residents actually live stay clear of tourists — but the places they work, shop, and pass through do not.

The one thing the ban did accomplish in New York: neighbourhood nuisance complaints dropped. Revolving-door party apartments in residential buildings became less common. That is a real benefit — and one that targeted regulation (occupancy limits, noise rules, host-present requirements) could deliver without eliminating the entire sector.

$100 in a hotel vs. $100 in a flat.

The economic circulation argument for short-term rentals is not made often enough, because it requires nuance. Here is the nuance.

When a visitor stays in a local host's apartment, spending does not vanish — it enters the local economy differently than hotel spending does. The host is a resident. Their rental income stays in the city. Their mortgage or rent is paid locally. The visitor, sleeping in a neighbourhood, tends to buy coffee around the corner, groceries at the market, dinner at a place without a tourist-menu prix fixe.

The point is not that hotels are bad. It is that the economic geography of tourist spending shifts meaningfully when accommodation is distributed versus concentrated — and that a blanket ban on residential hosting removes the accommodation type with the highest local multiplier.

Grau-Folch et al. (2023) estimated that tourist apartment visitors in Barcelona spend approximately 30% more in the local economy outside accommodation than hotel guests — a function of neighbourhood location driving more independent food and retail purchases.

The precedent board.

Barcelona is not the first. Every major city that has significantly restricted short-term rentals provides a data point. The pattern is not what the ban's proponents suggest.

The political economy of the ban.

The Airbnb ban has many genuine supporters — residents exhausted by tourist noise, activists fighting for affordable housing, city planners seeking breathing room. Their concerns are real. So are the interests that fund the lobbying effort.

This is not to say the ban is cynical. It reflects genuine political pressure from residents with genuine grievances. But the structure of who gains from it — and what the evidence says about its likely effectiveness — should weigh in how we evaluate it.

The interventions that show evidence.

If the goal is affordable housing and liveable neighbourhoods, the evidence points to a different set of tools. None of them fit in a press conference headline.
