Modular homes in Portugal: building can be simpler with the new rules

Modular homes in Portugal: what changes with Decree-Law No. 108/2026?

Since 1 October 2026, new rules have come into force that simplify planning procedures and expand the situations in which construction is possible through prior notification, without waiting for prior authorisation from the Municipal Council. The reform aims to make the process simpler and more predictable, while also placing greater responsibility on technicians and developers to comply with the applicable standards.

What does Decree-Law No. 108/2026 mean for those who want to build a modular or prefabricated home?

On land where the planning parameters are properly defined, including certain areas covered by approved subdivisions, it may be possible to proceed with construction after submitting the necessary documentation, paying the required fees, and complying with the formalities relating to the start of works. The application of this regime always depends on the characteristics of the land and the project: not all land allows for the construction of a residential home, and not all operations are subject to prior notification.
