Buying a Rustic House on the Costa Blanca: Is It Legal?

Somebody has told you that the villa you are looking at, the one up in the campo with the pool and the almond trees, needs an AFO. Maybe the agent said it. Maybe a friend who bought near Málaga said it. And now you are trying to work out how to get one for a house near Benissa or Dénia.

Let me save you the search. There is no AFO here.

My name is Daniel Bertomeu and I work alongside my father Juan Bertomeu, a lawyer with offices in Moraira and Dénia, here on the Costa Blanca, with over 30 years of experience. We are independent lawyers and tax advisors, which means we act for the buyer. Juan is the lawyer of the family, ICALI number 4643, and he has been doing this since 1991. Rustic land is where we see foreign buyers lose the most money, and it is almost always because they spent three months solving the wrong problem.

So, do you need an AFO certificate for a rustic house on the Costa Blanca?

No. AFO stands for asimilado a fuera de ordenación, which translates roughly as treated as outside the planning regime, and it belongs to Andalusian planning law. It does not exist in the Valencian Community. The expression does not appear once in the Valencian planning act. Not once.

I am not going to tell you the term exists nowhere else in Spain, because I have not checked every region and I am not going to pretend otherwise. What I can tell you is that here, in Alicante, Valencia and Castellón, it is not a document, not a certificate, and not a procedure. If somebody has told you to apply for one on this coast, they have read something written for a different region.

And I understand exactly how it happens. Andalusia has a huge English-speaking property market, the word travels through forums and dinner tables and estate agents, and it lands here as if Spain had one planning law. Spain does not. Planning is regional, and the region you are buying in is the one that decides.

Then what actually applies to a rustic house in the Valencian Community?

Two different things, and they do two different jobs. The first is what the law calls minimisation of territorial impact. The second is the fuera de ordenación regime, which does exist here, for buildings that no longer fit the planning that came after them.

Here is the part worth reading twice, because it is the opposite of what most people assume. The Andalusian AFO does not legalise anything. It is a recognition that the authorities can no longer act, and the law there says in plain words that it does not amount to legalisation. The Valencian minimisation route is a different animal. Where it applies, it can actually legalise the building work and the residential use.

So no, minimisation is not "the Valencian AFO". It is a stronger instrument with a much narrower door. And the door is a date.

The date that decides the whole thing: 20 August 2014

The Valencian route can only legalise the work and the residential use of buildings that were completely finished before the 20th of August 2014. That is the parameter. Everything else in the file is secondary to it.

So the first question we ask about a rustic house is never about the pool or the terrace. It is: when was this actually finished, and what proves it. Aerial imagery, the cadastral record, the certificate of works completion, old utility contracts. Not what the seller remembers.

Say two villas are on the market at 420,000 euros each, on the same lane, same view, same tiles. One was finished in 2011. The other was finished in 2016. They look identical in the estate agent's window and they are not the same asset at all. One of them may have a route into legality. The other one does not have that route, and no amount of paperwork later invents it.

Okay, but the surveyor says the council can no longer act. Is the house legal now?

Well, no. Those are two separate questions and the market mixes them constantly.

Enforcement running out of time means the administration can no longer order you to knock something down. It does not convert an unlawful build into a lawful one. The building stays what it is, and the consequences follow you into the things you actually care about: the occupation paperwork, the utility contracts, the mortgage valuation, and the day you want to sell it to somebody whose lawyer asks the same questions we are asking now. So when somebody tells you it is fine because the years have passed, that is half an answer, and it is the half that does not protect you.

What does the Valencian route actually involve?

There are two tracks, and which one your house is on depends on whether it stands alone or sits inside a cluster of houses that the town hall treats as a consolidated group.

For a group, the route runs through municipal planning, so it is a collective process and it moves at the speed of the town hall's own planning work. For an isolated house, which is the typical Marina Alta villa in the middle of a plot, the owner has to apply for an individualised declaration of minimisation of territorial impact. That decision is reserved to the full council sitting in plenary session, and it is taken as a rule-bound, case by case decision, a decisión reglada y singular in the words of the act. After that come a minimisation licence, a landscape integration study, and then the occupation side.

I am deliberately not going to tell you how long that takes or how it ends. It is a decision that belongs to the plenary of a specific town hall about a specific house, and anybody who promises you the outcome is selling you something.

There is one more filter that quietly kills a lot of these files. If the plot sits on protected land, or in a flood zone, a binding report from the competent authority comes into play. In the files we see, a good deal of rustic land in the Marina Alta turns out to be flood prone or classified as forest land. In our experience that is where the case ends, long before anybody gets to the plenary.

What to ask before you pay a single euro

Ask the seller, in writing, for these. If the answers are vague, that is your answer.

First, the exact date the building was completed, with something that evidences it. Second, whether there is any open enforcement or planning legality file on the property, and a municipal certificate saying so. Third, if anybody claims the house has been regularised, the actual plenary resolution and the licence that followed it, not a description of them. Fourth, the occupation title, and what the town hall requires for it on this class of land.

That fourth one matters more than people expect. Second occupation on this coast is normally a declaración responsable, a responsible declaration you file rather than a licence you wait for, and since the 1st of January 2024 that is the general rule: town halls no longer choose freely between the two. What does change is the class of land, and rustic is exactly where it changes, so what a specific town hall asks for on non-urbanisable land is not something to assume from the neighbouring municipality. And if a house does go down the minimisation route, the occupation title at the end of it is a licence, not a declaration. The town by town detail lives on our local sites for Dénia, Moraira and Jávea.

And do not expect the occupation paperwork to work as a way around an open file. If the town hall has something open on the building, that is the thing that has to be resolved first, and everything else waits behind it.

Does the Land Registry tell you any of this?

No, and this is where a lot of buyers relax too early. The nota simple tells you who owns it and what charges sit on it. It does not tell you whether the pool has a licence, whether the extension was declared, or whether the house was finished before or after a date in 2014.

Those are two separate investigations and you need both. The charges and debts side has its own logic and its own order of documents, and we set that out in how to check a Spanish property for debts and charges. The planning side is the one we are on now. A property can be perfectly clean on the registry and still be a house you cannot legally occupy.

If you are earlier in the process than that, and still deciding which part of the coast you want to be on, we built a short thing you can run through in about five minutes: where to buy on the Costa Blanca. It walks you through the towns and what tends to come up in each one, which is useful precisely because rustic land does not behave the same way in every municipality.

The tax side, in three sentences

Buying a resale property from a private seller triggers transfer tax, while buying from a business goes through VAT instead. Once you own it there is an annual non-resident filing on the deemed income even if you never rent the house out, and separate filings if you do let it, and those rental deadlines changed in 2026. Rates and deadlines move, sometimes mid-year, so I am not going to put a percentage on this page that ages badly. The tax side lives over at easy210spain.com. Here we stay on the planning and the contract.

What we check before a client of ours buys in the campo

We start with the completion date and what evidences it. Then the class of land and whether it carries any protection or flood classification. Then the town hall file: open proceedings, previous resolutions, and what the occupation route is in that specific municipality for that specific class of land. Then the registry and the cadastre against each other, and against what is actually built on the ground.

Only after that do we talk about the deposit contract, because the conditions that go into it depend entirely on what the four checks above found. The general shape of a purchase, deposit contract, notary, registry and the rest, is laid out in our guide to buying property in Spain as a non-resident, and how we run a purchase is on our conveyancing page. Conveyancing with us starts from 1,600 euros plus VAT. We do this from our offices in Moraira and Dénia, in person or remotely with a power of attorney if you cannot keep flying over.

Rustic houses on this coast can be wonderful. Some of them are also uninsurable, unmortgageable and unsellable, and the difference between the two is a set of questions you can ask in the first week instead of the last.

A quick legal note before you go

One last thing, and Juan makes me say it, because this is a law firm and a law firm has to say it. This article is general information, current as of July 2026. The Valencian planning act has been reformed repeatedly in the last two years, planning decisions belong to individual town halls, and a different class of land or one open file changes every answer above. It is not legal advice for your specific purchase, and reading it does not make you our client.

The planning law in this article has been reviewed by Juan Bertomeu, abogado, ICALI 4643.
