Fines for illegal houses can reach €150,000

The institutions urge great caution and thorough information when opting for modular, prefabricated, or “container” homes

The modular or industrial construction of homes is not in question; what is questionable is the misleading advertising by many companies and the lack of information among many residents when buying prefabricated houses, sources from the sector say.

“What is in doubt is the deceptive advertising of many companies and the lack of information among many residents when buying prefabricated houses.”

In this regard, both the municipality of La Oliva and the municipality of Puerto del Rosario have launched an informational campaign explaining to residents that every dwelling must be legalized and that it is essential to obtain this information at the municipal offices.

The message from both institutions is unequivocal: purchasing a container or a prefabricated home does not automatically grant the right to reside in it. Whether the construction is traditional or modular, all must comply with the same legal requirements.

It is essential to adhere to:

• Land classification: Installations cannot be placed on any plot.
• Building permit: Mandatory before any installation.
• Habitation certificate: Must meet first‑occupancy requirements.

Consequently, both institutions warn that campaigns generating false expectations can lead to an economic disaster for the buyer.
