Repairs to a listed building: do you need a permit in Portugal?

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

Repair and upkeep of a listed building, or one being listed, needs a licence unless the heritage authority has given a favourable opinion. With that opinion the work is exempt, and you file the opinion with the start-of-works notice.
