Swimming pool: do you need a permit in Portugal?

Independent site: we are not a public authority, and this is not legal or tax advice.

A swimming pool associated with a main building needs prior communication (comunicação prévia), not a full licence. You cannot choose a licence instead. Heritage and restricted areas have their own rules.

Answer

Prior communication (comunicação prévia)

Condition

The pool is associated with a main building, such as a house

No choice

Where prior communication applies, you cannot opt for a licence (art 4(6))

Pool not tied to a building

Not covered by this rule; the general rule is a licence (art 4(2)(c))

Heritage and restricted areas

Listed buildings, protection zones and areas under a public-utility restriction have their own rules (art 4(2)(d) and (h)); ask the council

Before you start

Tell the council at least 5 days before work begins, even for exempt work (art 80-A).

Council rules

Your council can add detail in its own building regulation where the law lets it, so ask before you start.
