New Law Caps Lisbon Rents at 3% Annually for 85,000 Tenants

The Assembly of the Republic passed the National Housing Stability Act 2026 on 8 July, setting a 3 percent annual cap on rent increases for residential leases in Lisbon and other municipalities. The change applies to roughly 85,000 existing rental contracts in the capital, according to housing ministry data released with the bill. Tenants whose leases renew after 1 January 2027 will receive written notice of the capped adjustment from their landlords.

Housing costs have climbed steadily in Lisbon since 2022, when the city recorded an average monthly rent of 1,050 euros for a two-bedroom unit. The new rules respond to repeated requests from municipal authorities for national tools to address supply shortages in older districts such as Mouraria and Arroios. The legislation states that the cap will remain in force through 2029 unless Parliament votes to extend or amend it.

Direct Effects on Household Budgets

For a household in the Intendente area currently paying 950 euros, the cap means the landlord may raise the rent by no more than 28.50 euros next year. Families renewing leases in 2027 will avoid the double-digit increases seen in 2024 and 2025, when some contracts rose by 8 to 12 percent. Local advocates note that the savings will stay within the same postal codes where many service-sector workers already live close to their jobs in hotels and restaurants.

The legislation also requires landlords to register the new rent amount with the municipal housing office within 30 days of any adjustment. Tenants who receive notices exceeding the 3 percent limit can file a complaint through the city’s online portal or at the Junta de Freguesia office. The government projects that the measure will affect 42 percent of Lisbon’s private rental stock, based on the 2025 housing census figures.

Implementation begins with training sessions for property managers scheduled for September in the Lisbon municipal chambers. Landlords must update their contract templates by December, and the city’s housing department will publish a list of compliant properties on its website each quarter. Analysts at the national statistics agency expect the first batch of capped renewals to reach tenants in late January 2027.
