Portugal's short-term-rental rules were rewritten once in 2023, partly reversed in 2024, and now sit inside a new EU-wide framework. What a buyer needs to check today before counting on Alojamento Local income.
Portugal's short-term-rental rules have moved twice in recent years — tightened in 2023, partly reversed in 2024 — and now sit inside a new EU-wide reporting framework. A buyer planning Alojamento Local (AL) income needs the current picture, not the headlines from either round of changes.
The EU framework behind it
EU Regulation 2024/1028 — the first bloc-wide short-term-rental framework — reached full effect in May 2026, requiring platforms (Airbnb, Booking.com, Vrbo) to report monthly per-listing activity data to national authorities across all 27 EU states, Portugal included. This sits on top of Portugal's own registration system, not instead of it.
RNAL: the mandatory registration number
Every short-term rental in Portugal needs a Registo Nacional de Alojamento Local (RNAL) number to operate legally and appear on booking platforms. A valid civil liability insurance policy — commonly cited at a minimum of €75,000 per claim, specifically covering short-term-rental activity — is a mandatory part of registration, not an optional extra.
Municipal containment zones
The 2024 reversal (Decreto-Lei 76/2024) made existing AL licences permanent and transferable again and lifted the national freeze that had been introduced the year before. But it didn't remove local control: municipalities — notably Lisbon, Porto and parts of the Algarve — can still declare containment zones ("zonas de contenção") where new AL registrations are suspended or capped. An existing licence in such a zone keeps its validity; a new application in the same zone may not be possible.
What this means before you buy
- Check whether the specific property already holds an active RNAL registration — an existing, transferable licence is worth more than the theoretical right to apply for one.
- Confirm whether the parish/municipality has declared a containment zone covering that address, and what it means for new applications.
- Budget for the mandatory insurance as a real, ongoing cost, not a formality.
- Treat a seller's claim of strong Airbnb income as a starting point to verify against the property's actual registration status, not a given.
FAQ
Does every short-term rental in Portugal need an RNAL number? Yes — it's the mandatory national registration, without which a listing can't legally operate. Did the 2024 law make it easier again? It restored permanence and transferability to AL licences and ended the earlier national freeze, but local containment zones in cities like Lisbon and Porto still restrict new registrations. Is the insurance requirement optional? No — a liability policy covering AL activity is a mandatory part of a valid registration. Does the EU regulation change Portugal's own rules? No — it adds EU-wide data reporting on top of Portugal's existing RNAL and municipal system.
How we help
We check a property's actual AL registration status and whether its municipality currently restricts new licences before you buy on the assumption of short-term-rental income. Informational only, not legal advice — this area has changed direction twice already in a few years, so confirm current status for the specific property and municipality before relying on it.
