Changing the use of an agricultural property: what it involves

When talking about changing the use of an agricultural property, it is worth distinguishing, as a first step, between different levels of change, because they do not all carry the same considerations. A first level is switching from one crop to another within the agricultural use itself — for example, moving from cereal to a woody crop, or from rain-fed to irrigated farming if you hold the corresponding right — which tends to be the simplest change from an administrative point of view, although it may require its own investment and agronomic planning. A second level is changing the type of use, for example from agricultural to livestock or forestry. A third, deeper level is switching from an agricultural use to a non-agricultural one, such as residential, industrial or tourism-related use.

This guide covers the general concept of these changes and why it is worth confirming them with the competent authority before acting; it does not detail the exact procedure for any specific case, because that depends on the urban-planning and sector-specific regulations applicable in each municipality and autonomous community, which can vary considerably from one place to another.

Clearly distinguishing these three levels from the outset helps you ask the right question of the right party: it makes little sense to go straight to the town council to ask about a simple change of crop, just as relying solely on an agricultural consultant to assess the feasibility of a change to residential use can leave out planning aspects that this professional has no reason to know in detail.

Switching from one crop to another while keeping the property's overall agricultural use tends to be the level of change with the fewest administrative implications, although it is not without practical considerations: moving from a herbaceous crop to a woody one involves a long-term investment that is worth planning carefully, and switching to an irrigated crop may require holding a recognised irrigation right, as explained in the guide on rain-fed versus irrigated farming within this same cluster.

Even within this simpler level of change, if the property has current agricultural commitments tied to some form of aid — for example, linked to a specific farming practice — it is worth confirming with a consultant specialised in the CAP whether the intended change is compatible with those commitments before carrying it out, since modifying the crop without that prior check could affect the status of that aid.

This type of change is also worth planning with the time a new crop takes to become established in mind: a herbaceous crop can be changed from one season to the next relatively easily, but a newly planted woody crop takes several years to reach full production, a period during which the property generates less income than it could once mature. Any decision of this kind should factor in that transition period as part of the overall project, not just the expected end result.

Changing the type of use of a property — for example, from an agricultural use to a livestock one, or adding forestry use over part of the land — tends to involve, besides the investment and technical planning itself, the need to check whether there is any restriction tied to the land's urban-planning classification or to specific sector regulations, such as forestry or livestock rules, which may require their own authorisations depending on the type of installation planned (fencing, sheds, drinking troughs, among others).

This type of change is worth approaching with enough lead time, first checking with the relevant town council on the land's current urban-planning classification and with the competent regional department on any applicable sector regulations, rather than starting the change of use and later discovering some overlooked restriction.

A common example of this level of change is bringing livestock onto a property that had until then been used exclusively for crops: besides the investment in fencing, drinking troughs or basic installations, it is worth confirming whether the area has any health-related restriction or minimum distance requirement relative to other farms or population centres, an aspect that is usually regulated at regional or even municipal level and that is worth checking before buying animals or putting up any installation.

The deepest change, from an agricultural use to a non-agricultural one — building for residential purposes, putting the property to industrial use or developing a tourism project, among other possible examples — is also the one most likely to involve a formal administrative procedure, generally tied to municipal urban-planning regulations and, where applicable, additional sector regulations depending on the type of project. Rustic or agricultural land tends to have, by its very classification, a limited range of permitted uses, precisely designed to protect its agricultural purpose or its natural value.

This guide does not detail what type of authorisation or procedure would be needed in each specific case, because that depends entirely on the land's urban-planning classification, the current municipal planning and the applicable regional regulations, aspects covered in more depth in this platform's legislation guides. What can be stated in general terms is that this type of change of use should never be taken for granted or assumed to be straightforward: it is worth confirming with the relevant town council, and where applicable with the competent regional department, the real feasibility of the project before buying a property with that intention, and certainly before starting any building work or activity.

This type of project tends to generate interest precisely because a property's value can be perceived as higher if it is put to a non-agricultural use, but it is worth being especially cautious with that expectation until you have a real administrative confirmation: buying a rustic property at a price that already anticipates an unconfirmed change of use is one of the most common ways of taking on a disproportionate risk relative to the potential benefit, if that change ultimately turns out not to be feasible.

Regardless of the level of change being considered, the general message is the same: get informed with the competent authority before acting, not afterwards. For changes within the agricultural sphere, the agriculture department or a specialised consultant can advise on the practical implications and, where applicable, on any current agricultural commitments. For changes that affect the land's classification or involve a non-agricultural use, the relevant town council and, where applicable, the competent department for urban planning or the specific sector regulation are the right parties to consult.

Buying a property while assuming that a specific change of use will be possible, without having confirmed it beforehand with the authorities, is a risk worth avoiding, especially when the purchase project depends directly on that change being achievable.

This guide relates to the rest of this platform's content on legislation applicable to rustic properties and on the CAP: any change of use can have both urban-planning and agricultural implications, and it is worth reviewing both angles rather than treating the question as settled after a single enquiry. The aim of this guide is to make clear that different levels of change exist, each with its own point of contact and its own complexity, not to offer a single procedure valid for every case.
