Key figures — as of 2026-08-26: EU Regulation (EU) 2024/1028 has applied since 20 May 2026, requiring Airbnb, Booking.com and similar platforms to verify and display registration numbers and automatically remove non-compliant listings — Lisbon City Council (CML) cancelled 6,765 AL registrations in February 2026, cutting the city's active licences from close to 20,000 to 11,779 — Santa Maria Maior, Misericórdia and Santo António remain under absolute containment, where new AL registrations are effectively prohibited — Portugal's national AL stock stood at roughly 111,000 registrations, growing only about 4% year-on-year, a marked slowdown from the pre-freeze pace.
The rule that changes everything for hosts
Foreign owners renting out Portuguese apartments on Airbnb or Booking.com no longer have room to be casual about paperwork. Under EU law that took effect on 20 May 2026, every short-term rental property must be registered with the relevant national or local authority and display a valid registration number on all listings, with data sharing making informal non-compliance effectively impossible to hide, and listings without valid registration numbers automatically removed by the platforms. For Portugal, that registration number is the Alojamento Local (AL) number issued via the Registo Nacional de Alojamento Local (RNAL).
The regulation itself, Regulation (EU) 2024/1028, doesn't invent a new licensing regime — the regulation applies from 20 May 2026, responding to the growth of platforms such as Airbnb, which has a major economic impact but also affects the availability of long-term rental housing, as authorities increasingly impose registration schemes. What it does is force the platforms themselves to police compliance. Airbnb has said publicly it's committed to helping everyday Europeans share their homes responsibly while sharing relevant information with policymakers, noting its City Portal already gives more than 450 European local authorities a single place to monitor listings, flag and take down non-compliant ones.
Lisbon's freeze collides with the EU mandate
The timing couldn't be worse for owners with lapsed paperwork in the capital. In February 2026, Lisbon City Council cancelled around 6,765 Alojamento Local licences, out of roughly 19,000 registered establishments in the city, for failing to submit proof of mandatory civil liability insurance. That single administrative sweep pushed active registrations from close to 20,000 down to 11,779.
Losing the licence is only half the problem — getting it back is the other. Lisbon's municipal AL regulation, in force since December 2025, splits the city into containment tiers: absolute containment applies where the AL-to-housing ratio is 10% or above, banning new registrations except in rare cases, while relative containment (5%–10%) requires CML authorisation for any new registration. Some freguesias eased slightly after the cancellations — Arroios, Estrela and São Vicente moved from absolute to relative containment, and Avenidas Novas exited containment altogether — but the historic core did not. Santa Maria Maior, Misericórdia and Santo António remain in absolute containment. A guide covering the reclassification is explicit that the mass cancellation did not open up vacancies for new licences in containment zones — even after nearly 7,000 registrations were removed, the ratios in those freguesias stayed well above the threshold.
GrowIN's calculation: a closed loop for foreign owners in the historic centre
Run the numbers together and the picture is stark. GrowIN Portugal's own calculation: the February cull removed roughly 41% of Lisbon's active AL stock in one stroke (a drop from near 20,000 to 11,779), yet a foreign owner whose licence lapses in Santa Maria Maior, Misericórdia or Santo António cannot simply reapply — those zones are locked under absolute containment regardless of how many slots the cancellations freed up elsewhere. Combine that with the EU's automatic delisting mandate from 20 May 2026, and an owner who misses one renewal — insurance proof, an expired registration, a paperwork gap — is now cut off from Airbnb and Booking.com immediately, with no realistic path back into the historic centre's licensed market.
"A missed insurance renewal in Lisbon's historic centre is no longer a fine — it's a permanent exit from the short-term rental market," says GrowIN Portugal Editorial.
What this means in practice
Portugal's overall AL market hasn't collapsed — the country counted roughly 111,000 active AL registrations, growth of about 4% on the previous year, a pace significantly slower than before the freeze. But that national figure masks sharply divergent local conditions. Owners outside containment zones, or in cities that haven't yet regulated, still face a separate deadline: municipalities that had more than 1,000 registered AL establishments by 31 December 2025 and haven't yet deliberated on local rules now have until 31 December 2026 to decide on their own regulations.
For non-resident owners managing property remotely, the practical checklist now runs: confirm your RNAL number is active and unexpired, confirm civil liability insurance is current and filed with CML (or your local câmara), and confirm your registration number is correctly displayed on every platform listing before 20 May enforcement catches up with older bookings still live from before the deadline. Anyone buying into the AL market for the first time should check containment status at freguesia and bairro level before signing anything — see GrowIN's guidance on property and tax obligations for non-residents in our tax & NIF hub, since AL income still needs to be declared correctly regardless of licence status.
What to watch next
Municipalities beyond Lisbon — Porto, and pressure points across the Algarve — are expected to finalise or tighten their own containment regulations before the December 2026 deadline, and CML updates its freguesia-level ratios monthly, so today's "relative containment" zone can tighten again with little notice. Owners should treat AL compliance as an ongoing administrative task, not a one-time licence application, and take professional advice before assuming a lapsed registration can simply be renewed.
