Living in a tiny house all year round: rules, comfort and daily life

Living in a tiny house all year round is a lifestyle choice that appeals for its simplicity. But a house lived in twelve months a year does not have the same requirements as a weekend retreat: the legal framework, utility connections, thermal comfort and the organisation of daily life all need to be thought through from the start.

Is it legal to live in a tiny house all year round?

Yes, within the right framework. The Code de l’urbanisme (French planning code) defines a caravan as a dwelling intended for temporary or seasonal leisure occupation: this is not the right status for a main residence. Two frameworks are suitable for permanent housing:

• A demountable dwelling (résidence démontable) used as a permanent home (article R111-51): an installation without foundations, occupied as a main residence for at least eight months a year, and easily and quickly demountable at any time. Laying out the plot requires a prior declaration (déclaration préalable) or a development permit (permis d’aménager).
• A building: a tiny house set on foundations, with a prior declaration (from 5 to 20 m²) or planning permission (permis de construire, over 20 m²).

In both cases, the land must allow it: the PLU (local urban plan) of the municipality has the final say. See our guides tiny houses and the law and where to site a tiny house.

Can you receive APL housing assistance in a tiny house?

Yes, in some cases. The Ministry of Housing clarified in 2024 that a tiny house that keeps a permanent means of mobility does not give entitlement to personal housing assistance (APL, aides personnelles au logement). However, a tiny house with no means of mobility, treated as a demountable dwelling used as a permanent home, may give entitlement to it, subject to three conditions:

1. it must be the applicant’s main residence, that is, occupied for at least eight months a year;
2. it must meet the decent-housing criteria, including a minimum level of energy performance;
3. the applicant must meet the usual conditions for APL, in particular in terms of income.

Among the decent-housing criteria: a main room of at least 9 m² with a ceiling height of 2.20 m, or of at least 20 m³; drinking water; a kitchen area with a sink; indoor sanitary facilities with a WC separate from the kitchen and a shower or bath supplied with hot and cold water; an electrical installation; waste-water drainage; adequate ventilation.

How do you get water and electricity all year round?

There are two options, which can be combined:

• Connection to public networks: drinking water, electricity, mains sewer. Note that a building that should have been authorised but was not cannot be permanently connected (article L111-12 of the Code de l’urbanisme).
• Self-sufficiency: solar panels and batteries, rainwater harvesting for permitted uses, off-mains drainage or dry toilets. For a demountable dwelling that is not connected, the planning application must include a certificate covering water, drainage, electricity and fire safety.

Everything is explained in our guide on tiny house utility connections.

Is a tiny house comfortable in winter?

Yes, if it has been designed for it. In a small volume, the house heats up quickly but also cools down quickly: everything depends on the building envelope.

• Insulation of the walls, the roof and the floor, which is exposed to the air on a trailer. On the Skywood, the insulation is rock wool, at least 10 cm thick in the walls and 14 cm under the floor. See our guide on insulation.
• Ventilation: a well-insulated house must renew its air to remove moisture from cooking, the shower and breathing. MVHR (balanced ventilation with heat recovery) does this while recovering heat from the extracted air. See our guide on MVHR.
• Heating, sized for the volume and the local climate.
• Windows and doors, whose quality and installation matter as much as the insulation.

How do you organise daily life in a small space?

• Sort through your belongings before moving in: a tiny house forces you to choose what you keep. Do it beforehand, not on delivery day.
• Plan storage at the design stage: stairs with drawers, cupboards under the beds, mezzanines (sleeping lofts), high-level storage.
• Plan an outdoor space: a terrace or a garden shed extends the house and holds whatever does not fit inside (bikes, tools, firewood). A shed of 5 to 20 m² requires a prior declaration, and planning permission above that.
• Air the house every day, in addition to the mechanical ventilation.
• Plan ahead for working from home: a desk area, a good internet connection and, if needed, a second unit such as a tiny house office in the garden.

Which tiny house should you choose to live in?

For one person or a couple, 15 to 20 m² can be enough if the layout is well designed. For a family, aim for a house with separate sleeping areas. For example, the Skywood and the Sharewood offer 30 m² and sleep six, and the Mobile Home offers 35 m² and two bedrooms. Our guide how to choose your tiny house will help you compare.

Key points

• Caravan status is intended for leisure; for permanent housing, aim for a demountable dwelling or an authorised building.
• A tiny house with no means of mobility, used as a decent main residence, may give entitlement to APL.
• Utility connections or self-sufficiency: plan for them as soon as you choose the land.
• Winter comfort depends on insulation, ventilation and heating.
• Storage and outdoor space make the difference in daily life.
