Local short-term-rental rules

At this review, no municipal AL containment-area regulation was found for Cascais; registration follows the national prior-communication regime.
Under Decreto-Lei n.º 76/2024, municipalities may declare containment areas — confirm the current status with the Câmara Municipal de Cascais before registering.

How to register a short-term rental

Gather the property's use title, the responsibility statement (termo de responsabilidade), the land registry (caderneta predial) and the tax authority activity declaration (CAE 55201 or 55204).
Take out the mandatory civil-liability insurance (minimum €75,000 per claim).
Submit the prior communication on the Balcão Único Eletrónico (eportugal.gov.pt), addressed to the president of the competent municipal council.
Receive the registration number (RNAL/RNT), assigned automatically — it is the only valid opening title and must appear in all advertising and on booking platforms.
Wait out the council's opposition window: 60 days, or 90 days in containment areas. With no opposition, the registration is confirmed.

Since Decreto-Lei n.º 76/2024 (in force 1 November 2024), AL registrations no longer expire and are again transmissible. The Extraordinary Contribution on Local Accommodation (CEAL) has been revoked.
