Only as an exception. In Andalusia, a detached single-family house on rural land (suelo rústico) that is not tied to a working farm is an extraordinary action: it needs prior authorisation from the town hall before the building licence (licencia de obra), it must not encourage new settlements to appear, and it carries a compensatory levy of 15% of the construction budget (article 22 of Andalusia's planning act, the LISTA). Agricultural structures tied to a working farm, such as an agricultural building or a store, are ordinary actions and go through a municipal licence.
Ordinary and extraordinary actions
The LISTA distinguishes two types of action on rural land:
- Ordinary (article 21): agricultural, livestock, forestry and similar uses, and the buildings linked to them. They are processed with a municipal licence.
- Extraordinary (article 22): uses of public or social interest that have to be located on rural land and, on the terms set by the regulations, detached single-family houses that do not lead to the formation of new settlements.
What a detached house requires
- Prior authorisation from the town hall that qualifies the land, with a public information period of at least one month and a hearing for the adjoining owners.
- A binding report from the regional ministry (Consejería) responsible for spatial planning when the action has an impact beyond the municipality.
- Time limit: the town hall has six months to decide on the authorisation, and silence means refusal.
- A compensatory levy of 15% of the material execution budget of the works (presupuesto de ejecución material).
- A building licence after the authorisation.
In addition, the local plan (PGOU) of your municipality may set a minimum plot size, distances and other conditions.
A worked example
For a detached house of 150 m² with a construction budget of €150,000, the compensatory levy would be €22,500, before the licence, municipal fees, professional fees and VAT. You need to allow for it before you buy the land.
Before you buy a rural property
Ask for a feasibility report. Within a few days you will know what class of land it is, whether there is any route to building on it, how much it would cost and whether anything already built has a problem.
Frequently asked questions
Can I put a prefabricated house on my rural land?
A prefabricated house is a dwelling for all purposes. If it is not linked to the farm, it follows the same route as any detached house: prior authorisation and the 15% levy.
What about a building for farm tools and equipment?
If it is linked to your farm and proportionate to it, it is an ordinary action: a municipal licence with no prior authorisation.
