Buying property in the Azores: the archipelago runs its own agricultural reserve, not Portugal's

Almost everything written in English about buying land in Portugal describes two national reserves, the RAN and the REN, and the statutes behind them. In the Azores, the agricultural half of that answer is the wrong statute.

The short answer: the archipelago has its own Reserva Agrícola Regional (RAR), set up by Decreto Legislativo Regional 32/2008/A and republished in its current form by Decreto Legislativo Regional 20/2019/A, in force since 6 September 2019. On RAR land the soils "devem ser exclusivamente afetos à agricultura" — must be used exclusively for agriculture — and building is listed among the prohibited acts. The exception that allows a house is written for working farmers: the applicant must have been established as a farmer for at least three years, or be acting under a first-installation project, on their own rustic property, for own and permanent residence on the holding. A house built that way is inalienable for ten years, the charge is registered against the title, and only one dwelling per applicant may be built in the reserve at all.

Everything below is read from the regional instruments on 9 November 2026. Where our conclusion is a reading rather than something the text states, this page says so.

The Azores have a Reserva Agrícola Regional of their own, and it is not the national RAN

The national agricultural reserve regime, Decreto-Lei 73/2009, provides in its own article 48 that it applies to the autonomous regions subject to the adaptation each region introduces by regional legislative decree. The Azores did not adapt it; they had already legislated their own reserve in July 2008, before the national statute existed, and have amended it twice since — by DLR 33/2012/A and by DLR 20/2019/A, which altered articles 5, 8, 9, 14 and 15 and republished the whole regime as an annex.

So a buyer looking at a plot on São Miguel, Terceira, Pico or Faial is dealing with the RAR, administered by its own managing entity, and not with the RAN delimitation that a mainland lawyer would check. The register of what is in it is also regional: article 19 of the republished regime provides for nine parcel maps, one for each island of the archipelago, at 1:25,000.

The regime's reach is defined by soil quality rather than by location: article 3 takes in soils of land-use capability classes I to IV and other soils worth protecting, with explicit attention to islands where those classes are thinly represented. The instruments are at the Azores Reserva Agrícola Regional regime.

What the Azores reserve prohibits: building is on the list, not an exception to it

Article 4 of the republished regime is the general rule, and it is unusually blunt:

> "Os solos da RAR devem ser exclusivamente afetos à agricultura, sendo proibidas todas as ações que diminuam ou destruam as suas potencialidades agrícolas, ou que se traduzam na sua utilização para fins não agrícolas, designadamente: a) Vias de comunicação e acessos, construção de edifícios, aterros e escavações"

Roads and accesses, the construction of buildings, embankments and excavations are the first category named. The article continues with the dumping of urban or industrial waste, excessive volumes of slurry and manure, and actions causing erosion, landslides, waterlogging or flooding.

A reader coming from a listing that describes a plot as "ideal for a villa" should notice what this means. On RAR land the planning question is not how long permission takes. Construction is in the prohibited list, and the only way to a house is through one of the exceptions in article 5 — which were written for farming, not for settling.

The Azores exception that allows a house is written for working farmers

Article 5(1) sets out the exceptions, and the two that concern housing are narrow:

• (b) housing "para agricultores instalados há pelo menos três anos ou ao abrigo de um projeto para primeira instalação, nos seus prédios rústicos, para fixação em regime de residência própria e permanente na exploração agrícola" — for farmers established at least three years, or under a first-installation project, on their own rustic properties, for own and permanent residence on the agricultural holding.
• (c) works of reconstruction and extension of existing buildings, provided they were already and continue to be used as an own permanent residence.

The rest of article 5(1) covers agricultural works and farm buildings, agritourism, renewable-energy equipment where no economically and technically viable alternative exists outside the RAR, compliance with legal obligations, works of recognised public interest, cultural and environmental defence, and telecommunications and fuel stations.

Limb (c) is the one worth knowing about before viewing. An existing house on reserve land that is already someone's permanent home can be reconstructed and extended. Bare reserve land is a different proposition entirely, and limb (b) decides whether you are a candidate for it.

Who counts as a farmer in the Azores: an income test and a working-time test, with pensioners excluded

The regime defines the word rather than leaving it to custom:

> "«Agricultor» a pessoa singular, cujo rendimento bruto proveniente da atividade agrícola é igual ou superior a 50 % do seu rendimento global e que dedica pelo menos 50 % do seu tempo total de trabalho à mesma exploração"

So an individual whose gross income from agriculture is at least 50% of total income and who devotes at least 50% of total working time to the same holding. The definition then excludes, expressly, anyone who draws a retirement or invalidity pension under any social security regime, and anyone carrying on an activity that occupies more than half the professional working hours a full-time worker in that profession would normally work.

Read against the profile of most people searching for Azorean property, that is decisive. A remote worker, an early retiree, a pensioner from another EU country and a buyer keeping a job elsewhere are each excluded by name or by arithmetic — not refused on the merits, but outside the class the exception is written for.

A house built on Azorean reserve land cannot be sold for ten years

This is the provision that most often surprises, and it is article 6:

• 6(1) — houses built under the farmer exception are inalienable for ten years from the issue of the alvará de utilização, the use permit, except where the sale is made together with the whole agricultural holding and the buyer meets the requirements demanded of the seller.
• 6(2) — that charge must appear in the use permit issued by the municipality that licensed the works, and it is subject to land registration, so it runs with the title rather than living in a file.
• 6(3) — the municipality and the applicant each send the documents to the RAR managing entity within 30 days of issue.
• 6(4) — "Fica limitada a construção na RAR a apenas uma habitação por requerente": construction in the RAR is limited to one dwelling per applicant.

The practical consequence for anyone buying an existing property rather than building: a house on reserve land may carry a registered ten-year restriction, and the two places it shows are the use permit and the land register. Both are checkable before signing, and neither is in the listing.

Who decides an Azores RAR application, and what the opinion is worth

Article 8 splits the decision. The exceptions in article 5(1)(a) to (c) — farm works, farmer housing, reconstruction and extension — are confirmed by the entidade gestora da RAR, the regime's managing entity. The exceptions in (d) to (i), the agritourism, energy, public-interest and infrastructure limbs, additionally need a favourable opinion from the relevant members of the regional government.

Article 15 puts the instruction of infringement proceedings with the same managing entity, and article 7 lists what an application carries: social-security proof, income declarations and property certificates — the documents that prove the income and working-time test rather than assert it.

What this changes about the national rules, and what it does not

Three things carry over from the mainland and one does not.

The REN, the ecological reserve under Decreto-Lei 166/2008, is a separate regime from the agricultural one, and its article 46 contains the same clause as the RAN's article 48: it applies to the autonomous regions subject to regional adaptation. This page makes no claim about how the REN is delimited in the Azores — we have not read an Azorean adaptation of it, and the absence of a reading is not a finding that none exists.

The classification of soil as rustic or urban is the planning question that precedes both reserves, and it is decided in municipal and inter-municipal plans. Nothing we read in the regional instruments displaces that.

Transfer tax, stamp duty and the agency rules are national. What a purchase costs in IMT, including the 2026 non-resident rate that does not reach land, is in buying land in Portugal. How to check that an agent is licensed, and why an unwritten mediation contract is void, is in estate agents in Portugal.

Our reading, stated as a reading: the regional regime we read does not mention Decreto-Lei 73/2009 anywhere, so we do not say that it formally displaces the national RAN in the Azores. What we say is narrower and sufficient: the instrument that regulates agricultural reserve land in the Azores, and the one an application is decided under, is the regional one.

What we could not establish about Azorean property rules

• An Azorean adaptation of the REN. Decreto-Lei 166/2008 article 46 provides for one; we did not read one, and we do not conclude from that that there is none.
• The formal relationship between the RAR and the national RAN. The regional text is silent on it, and we are not inferring a repeal from silence.
• Which parcels are in the RAR. Article 19 provides for nine island maps at 1:25,000; those maps, not this page, are the answer for a specific plot.
