Porto’s Short-Term Rental Containment Zones: 2026 Guide

Porto was the first Portuguese city to create a system of containment zones for short-term rentals — and the regulation defining them has been in force since December 2024. If you own or are considering a short-term rental property in Porto, understanding which zone your property falls into is the essential first step before anything else.

This guide explains what containment zones are, which parishes are affected, what is and is not permitted in each type of zone, and how to verify the classification of your specific address.

What is a short-term rental containment zone?

A containment zone is a geographic area where the municipality has determined that the number of short-term rentals already represents significant pressure on the local housing market. In these zones, opening new short-term rentals — known in Portugal as Alojamento Local (AL) — is restricted or prohibited, except in specific circumstances defined by law.

The system works through a pressure ratio calculated per parish: the number of short-term rentals registered in the RNAL (Portugal’s national short-term rental registry) divided by the number of residential properties with an active water meter from AdP (Águas do Porto, the city’s water utility). When that ratio reaches or exceeds 15%, the parish is classified as a containment area.

Under Article 4 of Decree-Law 76/2024 — Portugal’s legislation governing short-term rentals since November 2024 — municipalities have the authority to adopt local regulations with this type of zoning. In Porto, that authority was exercised through Municipal Regulation 1462/2024, published in Portugal’s Official Gazette (2nd series, No. 246, 19 December 2024), which reinstated the original April 2023 regulation. For a detailed breakdown of the national legislative changes, see our article on Portuguese short-term rental legislation — October 2024.

Porto’s containment zones in 2026

Based on July 2026 data, five parishes in Porto’s historic centre exceed the 15% threshold and are classified as containment areas:

Parish	Registered STRs (RNAL)	Housing units with AdP meter	Pressure ratio	New registrations
Vitória	966	1,610	60.0%	Not permitted (except exceptions)
São Nicolau	530	1,129	46.9%	Not permitted (except exceptions)
Sé	1,019	2,588	39.4%	Not permitted (except exceptions)
Santo Ildefonso	2,458	7,025	35.0%	Not permitted (except exceptions)
Miragaia	346	1,630	21.2%	Not permitted (except exceptions)

The combined pressure ratio across these five parishes stands at 38.0% as of July 2026. All five form part of Porto’s historic centre, a UNESCO World Heritage Site.

Sustainable growth zones in Porto

The remaining ten parishes in Porto are classified as sustainable growth areas. In these zones, opening new short-term rentals is permitted, but each parish has a maximum cap — the numerus clausus — calculated individually. When that cap is reached, the parish automatically becomes a containment zone.

Parish	Ratio (Jul. 2026)	Available slots (numerus clausus)	Maximum total
Paranhos	1.1%	3,959	4,262
Ramalde	0.6%	2,825	2,946
Campanhã	1.1%	2,388	2,575
Bonfim	8.3%	1,053	2,374
Cedofeita	9.9%	803	2,377
Lordelo do Ouro	0.9%	1,575	1,673
Foz do Douro	2.8%	710	875
Aldoar	0.4%	877	898
Massarelos	7.8%	326	677
Nevogilde	0.8%	356	375

The numerus clausus figures are updated by mayoral decree without requiring a formal revision of the regulation. Cedofeita (9.9%) and Massarelos (7.8%) are the parishes with the smallest remaining capacity. Porto City Council’s interactive map at geo.cm-porto.pt/regulamentoal/mapa/ shows live pressure ratios and available slots per parish.

How is the pressure ratio calculated?

The pressure ratio is calculated by dividing the number of short-term rentals registered in the RNAL by the number of residential properties with an active water supply meter from AdP. It does not use census data — it uses water meters as a proxy for housing that is genuinely occupied.

This means a vacant property without an active water meter does not count in the denominator. The methodology makes the ratio more sensitive to actual pressure on housing in real use.

Can I open a new short-term rental in a containment zone?

The general rule in a containment area is that new short-term rental registrations are not permitted. However, there are specific exceptions set out in Article 5 of the sustainable growth regulation. Any of the following circumstances may allow for exceptional authorisation:

• New or rehabilitated buildings with a mixed-use character (social, cultural or affordable housing), where at least 50% of the area is housing and 20% is affordable housing for a minimum of 25 years
• Operations that promote street-level commerce: 60% of the ground floor for retail and 20% of the remaining area for affordable housing for a minimum of 25 years
• A building, unit or part thereof that has been entirely vacant for more than three years
• A property that has undergone rehabilitation works in the last two years enabling it to move up two conservation levels (from poor or very poor condition)
• A property that changed use from industrial to residential or services in the last two years
• New buildings constructed following demolition of a property in very poor condition or at risk of collapse
• Demolition of structures in private courtyards with no architectural value, resulting in surface sealing below 70% of the plot

In any of these cases, the municipality carries out a mandatory prior inspection before registration. The inspection is arranged by municipal services, and any inability to attend must be communicated within 15 days.

Room rental is always permitted

There is one universal exception: the room rental modality — where the property owner rents out rooms within their own primary residence, with a maximum of three rooms — can always be authorised in any containment area, regardless of the conditions listed above. This exception is expressly set out in Article 5(4) of the regulation.

What happens to existing short-term rentals in containment zones?

Establishments with a valid registration in containment areas continue to operate normally. The regulation does not retroactively cancel existing registrations. What changes is the impossibility of opening new short-term rentals in those zones (except under the exceptions above) and the requirement to comply with all current legal obligations.

Key obligations include: a valid liability insurance policy with a minimum cover of €75,000 (mandatory since March 2025), guest registration in SIBA (Portugal’s official guest reporting system), and keeping registration details up to date. Non-compliance can lead to cancellation — in May 2026, Porto City Council confirmed the start of proceedings to cancel 1,413 short-term rental registrations with irregularities, with the possibility of regularisation.

How to check if your property is in a containment zone

Porto City Council provides an updated interactive map at geo.cm-porto.pt/regulamentoal/mapa/. You can search for a specific address and check the zone classification, the current pressure ratio, and the available capacity for new short-term rentals in that parish.

The Portal do Munícipe — Porto’s online municipal services portal — also allows you to access short-term rental information and submit enquiries directly to the council.

If you are looking to register a short-term rental in Porto and your property is in a sustainable growth area, the process goes through the Balcão Único Eletrónico (Portugal’s single digital business registration counter) at ePortugal.gov.pt — the municipal opposition period is 90 days (60 days in containment areas). For full details on the licensing process and requirements, see our guide on the short-term rental licence in Porto.

2026: active enforcement phase

After years of approving and reinstating the regulation, 2026 marks the transition to active enforcement. In May 2026, Porto City Council announced the start of cancellation proceedings against 1,413 short-term rentals with irregular registrations — most due to missing liability insurance reported through the official portal, outdated records, or zoning violations.

For property owners with valid registrations and a compliant status, the direct impact is limited. But the signal is clear: the municipality is actively enforcing the rules, and non-compliance has consequences.
