Before you buy
Is a modular home legal in the Canaries?
Yes, but with a permit. The idea that a demountable module escapes the paperwork because it's demountable is the most expensive mistake out there. Here is what the law says, point by point, with the source alongside.
This guide is for orientation only. Planning in the Canaries is split between the regional government, each island council and each town hall, and what applies in one municipality may not apply in the next. Before buying anything, check your specific case with your town hall.
The law that governs all of it
Ley 4/2017, de 13 de julio, del Suelo y de los Espacios Naturales Protegidos de Canarias
This is the law that governs land use in the Canaries. Every statement on this page cites the article it comes from, so you can go and read it yourself.

Nine things worth knowing
-
01
The law names prefabricated houses, specifically
Nothing needs interpreting and nothing needs arguing by analogy: the list of works requiring a municipal planning permit names this case explicitly. And it heads off the usual objection, the one that says it doesn't count if you can take it away tomorrow.
«La ubicación de casas prefabricadas e instalaciones similares, ya sean provisionales o permanentes.»
Ley 4/2017, artículo 330.1.d)
-
02
"Fixed, mobile or demountable": how it's built doesn't matter
When defining what counts as residential use on rural land, the law draws no line between what is fixed to the ground and what can be moved: all three go in the same bracket. The myth that a module escapes the paperwork because it is demountable is refuted by three words of the text itself.
«El uso residencial, con el carácter de uso ordinario, comprenderá las construcciones e instalaciones fijas, móviles o desmontables destinadas a vivienda unifamiliar.»
Ley 4/2017, artículo 60.1
-
03
On rural land, not just any plot will do
For the home to count as an ordinary use it must sit on land classified as a rural or agricultural settlement. If your plot is rural but lacks that classification, the use is not ordinary and an express declaration of public or social interest is required before the town hall can grant a permit. That is not one more form: it is a different league.
Ley 4/2017, artículos 60.1.a) y 74.1 y 74.2
-
04
In an agricultural settlement, you must prove you farm it
If the plot is in an agricultural settlement, the home must be directly tied to an actual farming operation. And note the detail that catches many people out: first occupation is only possible after proving the land has been put into production, or that the holding maintains its farming activity. You farm first, then you move in.
Ley 4/2017, artículo 60.1.b)
-
05
Every home needs an architect's project, with no minimum size
It's widely claimed that below 20 m² no project is needed. It isn't so, and that threshold appears in no regulation. The Building Regulation Act does exempt work of minor scale and technical simplicity, but it expressly carves anything residential out of that exemption. A dwelling is residential by definition, whatever its size: all eight models on this site need a project.
«…excepto aquellas construcciones de escasa entidad constructiva y sencillez técnica que no tengan, de forma eventual o permanente, carácter residencial ni público…»
Ley 38/1999, de Ordenación de la Edificación, artículo 2.2.a). El proyecto debe cumplir el Código Técnico de la Edificación (Real Decreto 314/2006)

06
The habitability certificate no longer goes by that name
Almost everything you'll read about the Canaries is out of date on this point. Since 2019 the procedure changed its name and its form: where a certificate used to be requested, you now file a prior notification with its technical certification attached. The habitability conditions you must meet are unchanged; what changed is the document that evidences them.
«Todas las referencias contenidas en el Decreto 117/2006, de 1 de agosto, a la cédula de habitabilidad y sus efectos se entenderán realizadas a la presentación de la comunicación previa a la primera ocupación o cambio de uso con destino a vivienda…»
Decreto 182/2018, de 26 de diciembre, Reglamento de Intervención y Protección de la Legalidad Urbanística de Canarias (BOC nº 5, de 9 de enero de 2019), disposición derogatoria única, apartado 2. El procedimiento está en el artículo 33 del Reglamento
-
07
Without that document, utilities cannot connect you
It isn't that it's hard: the law forbids them. Water, electricity, gas and telecoms companies are required to demand the prior notification of first occupation before contracting, and to refuse service to anything that cannot evidence its planning title. That's why a module without paperwork isn't a home: it's an object with no power.
Ley 4/2017, artículo 336, apartados 1 y 5.a)
-
08
What it costs to install it without a permit
Building without the required title is a serious infringement in the case of major works, fined from €6,001 to €150,000. If the land is a protected natural space or rural land protected on environmental grounds, it becomes very serious: €150,001 to €600,000. And on those specially protected sites there is a separate category calculated on the works themselves, from 100% to 200% of their value.
Ley 4/2017, artículos 372.3.a) y 373.b) para las graves; 372.4.a) y 373.c) para las muy graves; artículo 382 para el porcentaje sobre el valor de la obra

09
And if it can't be legalised, it comes down
The fine is only part of it. Where the building cannot be legalised, or is not legalised in time, the restoration measure is demolition, and the operations include cutting off water, electricity, gas and telecoms. Demolition is paid for by whoever installed it, so on top of the fine you add removal and the loss of the module itself.
Ley 4/2017, artículo 358, apartados 1.a) y 2.a)
The order it's done in
Five steps. None can be skipped and the order matters: if you buy before the first one, you can end up with a module you can't place on your land.
-
01
Planning certificate from the town hall
It's called a cédula urbanística and it states the classification and conditions of your specific plot. The town hall has fifteen days to issue it if you give the cadastral reference, and a month otherwise. It's valid for a year. It comes first because it can end the conversation, and because sticking to what it says exempts you from liability if the town hall got it wrong.
Ley 4/2017, artículo 328
-
02
Geotechnical survey
It analyses the ground and determines the foundations needed. A chunk of budget nobody expects comes out of here.
-
03
Stamped technical project
Drawn up by a registered architect. Required for any dwelling, with no minimum size, and without it you cannot apply for the permit.
Ley 38/1999, artículo 2.2.a)
-
04
Permit or prior notification
Depending on the town hall and the type of land, it will be a building permit or a prior notification. It is not your choice: the law lists which route applies.
Ley 4/2017, artículos 330 y 332
-
05
Prior notification of first occupation
The document formerly known as the habitability certificate. It is the last step and the one that lets you contract electricity and water and register your address. Without it, none of the rest is worth anything.
Decreto 182/2018, artículo 33 del Reglamento, y Ley 4/2017, artículo 336
What isn't in the module's price
- IGIC: in the Canaries you don't pay VAT, you pay IGIC.
- Sea freight if the module travels to another island.
- Foundations, which come out of the geotechnical survey.
- Architect's project and professional stamping.
- Town hall permit fees.
- Electricity and water connections up to the plot.
This page was written so you know what to ask, not to replace a professional. eContainer Canarias manufactures and installs modules: we are not architects or planning agents, and we do not process your permit. Each town hall and each island council has its own powers and its own criteria. Always check your specific case before making a purchase decision.
