Garden carport: do you need a permit in Portugal?

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

A carport is not named in the law. It is exempt only if it fits the minor-works limits for an outbuilding: up to 2.2 m high, up to 10 m² and not facing the public road. Anything bigger needs a licence, or prior communication where art 4 allows it.

Answer

Exempt only inside the outbuilding limits; otherwise a licence

General rule

A permanent structure is a building work (edificação, art 2(a)) and needs a licence unless an exemption applies (art 4(2)(c))

Outbuilding limits

Not more than 2.2 m high, 10 m² or less, not facing the public road (art 6-A(1)(a))

Before you start

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

Heritage exception

Minor-works exemptions do not apply to listed buildings, buildings in the protection zone of a listed building (window frames excepted), or buildings inside listed groups or sites (art 6-A(2)).

Council rules

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

Legal basis

RJUE art 2(a), 4(2)(c) and 6-A(1)(a), RJUE (Decreto-Lei 555/99) as republished in the Annex of Decreto-Lei 108/2026
