Short answer
Yes, properties in historic zones, especially UNESCO-listed areas like Angra do Heroísmo, are subject to strict heritage rules. Renovations and alterations must be approved by heritage authorities, which can add time and cost. Before buying, check with the local council and heritage bodies about what is allowed. Always confirm the specific restrictions for the property.
