Planning permission in Andalucía is not something to guess at. The legal position can depend on municipal rules, land classification, the nature of the works and the exact intervention mechanism required under current law.
Before treating a property as developable or alterable, the planning status, local municipal position and the proposed works all need to be reviewed carefully. Under LISTA, some acts require licence, while others may fall under declaración responsable or comunicación previa.
If future works are part of the value proposition, planning advice belongs before exchange, not after completion.
