Lease Agreement in Porto — Model NRAU 2026
Porto has a very competitive rental market, especially in the refurbished historic neighbourhoods of the centre (Cedofeita, Bonfim, Paranhos), where university and tech demand overlap. Contracts in Porto have their own specifics: refurbished properties require an up-to-date energy certificate; the presence of university students raises the question of 10-month contracts vs. annual contracts; and distance to the Metro is often a reference clause in the listings.

Registration with the Tax Authority (AT)
In Porto, registration of the lease agreement is done online on the Portal das Finanças (e-balcão → Arrendamento → Comunicar contratos) within 30 days. For properties in Porto's historic centre (Cedofeita, Miragaia, São Nicolau, Vitória), it is common for Tax Offices Porto 1 and 2 to have high registration volumes: the e-balcão avoids queues. The proof of registration must be kept by the landlord for the entire term of the contract.
Stamp duty
For a lease agreement in Porto with a median rent of €1,100/month, the Stamp Duty due is €110 (10% of one month's rent). This tax is the landlord's responsibility and must be paid within 30 days after registration of the contract. For multi-year contracts (e.g. 3 years), the Stamp Duty is calculated on 3x the monthly rent with no discount; for 5+ years, there is a 50% discount on the amount of the tax.
Landlord and tenant obligations
In Porto, the landlord is obliged to hand over the property with a valid energy certificate (minimum F for refurbished pre-1990 properties), with all infrastructure functioning (water, electricity, gas). For properties in the classified historic centre, works require prior authorisation from the CMP and DRCN Norte. Ordinary maintenance works are the landlord's responsibility; extraordinary maintenance works (e.g. roof replacement) may be passed on to the tenant by contractual agreement.
Frequently asked questions
Can a landlord in Porto make a 10-month contract for students?
Yes, but with restrictions. The NRAU allows contracts for less than 1 year only for leases for non-permanent housing (displaced students or temporary workers). In this case, the contract must explicitly state the non-permanent purpose. For ERASMUS students or Portuguese nationals who have relocated to attend university in Porto, this arrangement is legal and common. For permanent residential leases, the minimum term is 1 year.
What is the difference between a lease agreement and alojamento local in Porto?
A residential lease (NRAU) is a contract for a minimum of 1 year, with the tenant as a permanent resident protected by the Civil Code. Alojamento Local (AL, local tourist accommodation) is a short-term tourist lodging service, subject to municipal licensing and registration in the Registo Nacional de Alojamento Local (RNAL). In Porto, the City Council has imposed moratoriums on the opening of new AL units in several parishes of the historic centre since 2023. Mixing AL with NRAU leases is illegal and creates tax risks.
How does automatic renewal of lease agreements work in Porto?
Lease agreements with a 1-year term renew automatically for an equal period (1 year) unless renewal is opposed by notice given at least 120 days in advance (tenant) or 240 days in advance (landlord). For contracts of less than 6 months, the landlord's notice period is 120 days. For contracts of 2+ years, the landlord's notice period for non-renewal is 240 days before the end of the term. Failure to observe the notice periods requires the contract to be maintained.
