Building licences for home improvements in Spain are obtained from the local Town Hall and come in two main forms:
-Minor Works Licence or “obra menor” which covers all minor refurbishments such as refitting your bathroom or kitchen, retiling, painting and any other small works which do not include any structural changes. Most of the usual home improvements would be covered by this type of licence
-Major Works Licence or “obra mayor” which covers more substantial works and those affecting structural nature such as property extensions, remodelling of property layout, building a swimming pool.
