§ 1The term
AFO stands for asimilado a fuera de ordenación. It is a status created in some regional rules for buildings that were built without a licence, or in breach of the plan, but that can no longer be made the subject of measures to restore the legal position. The building is tolerated and treated in some respects like a building that is out of planning. Regional rules differ, and the name, requirements and effects of the status vary. The outline below is general, and the regional law decides the details. It is part of the chapter on irregular properties in illegal builds in detail.
§ 2What the status means
The status recognises a situation of fact: the building exists, it has been there long enough, and the authorities can no longer order its demolition. It does not make the building fully lawful. The owner can usually obtain a certificate from the town hall that recognises the status, which helps with utilities, registration and sale. Without the certificate the building may be in a weaker position.
§ 3What the owner can do
An owner of an AFO home is usually limited to the works that keep the building safe, healthy and in good repair. Works that increase the volume, change the use or intensify the occupation are usually not allowed. If you plan to extend, add a pool or divide the home, ask the town hall whether it is possible. The answer may be no. The wider rules on regularisation are in how legalising works.
§ 4What the certificate gives
The certificate can allow the connection of utilities, the registration of the building and a basis for sale. It does not remove every restriction. Ask the town hall to state in writing what the certificate covers and what it does not. Ask also how the status affects insurance and taxes.
§ 5Financing
Lenders judge AFO homes case by case. Some will lend with lower limits, others will not lend. Tell your lender that the home is AFO before you reserve. A cash purchase is simpler, though the resale issue remains.
§ 6Land type
AFO status is often met with houses on rural land, where building rules are stricter. The category of the land matters to what is possible. The rules are explained in the rules on rustic land.
§ 7Before you buy
Ask the seller for the certificate, or ask the town hall whether the status can be obtained. Have your lawyer read the certificate and the local rule, and price the home as a limited-use property. If the seller cannot show the status, take the home as unresolved. A promise of “AFO” in the listing is not a certificate.

FAQRelated questions
Is an AFO home legal?
It occupies a middle position: it is not treated as a lawful building, but it is protected from some enforcement. The owner can usually obtain a certificate that recognises the status. Ask what the certificate allows, and how lenders and utilities treat it.
Can I improve an AFO home?
Only within limits. In general the owner may carry out the works needed to keep the building safe and habitable, but not extensions or changes that increase its volume or change its use. Ask the town hall what is allowed for the specific property.
Will a bank lend on it?
Some lenders do and others do not. A bank that lends may value the property lower and lend less. Ask your lender early, before you reserve, and make the purchase conditional on finance if you need it.
