A tiny house in Italy, with your paperwork in order

Consolidated building act, DPR 380/2001

What the law says about tiny houses

The law does not look at the wheels but at the use. Article 3 lists among new buildings the installation of "light structures, including prefabricated ones", including caravans, motorhomes and mobile homes, when they are used as a home or a workplace.

• The first question is always the plot: the municipality's zoning plan and building regulations say whether a home can be built there, how large and what it should look like.
• The regions can extend the list of works that need no permit and name other works that need a permit or a SCIA (art. 6, comma 6; art. 10, comma 3; art. 22, comma 4), so the law of your region matters too.
• In an area protected for its landscape or cultural heritage, you also need the opinion or authorisation of the protection authority (art. 22, comma 6).
• Always ask your municipality, before ordering, what applies to your plot. The municipality decides, not us.

Our houses

All our houses, measured against the rules

In Italy size does not change the building permit: to live in it you need the permit, whatever the house. It does matter for energy: below 50 m² of usable floor area a detached building is excluded from D.Lgs. 192/2005. Here the area is the external one, length times width; the usable area is a little smaller.

The exclusion below 50 m² concerns D.Lgs. 192/2005; other rules, such as the obligation to use renewable sources in new buildings or the energy rules of some regions, may still apply. Your designer checks this. The mobile models have light insulation (wall about U 0.44), the semi-mobile and non-mobile houses much more. Ask us for drawings and U-values of the model you are interested in.
