A house up to 70 m² without a permit: what notification instead of a building permit actually changes

'A house without a permit' sounds like it sidesteps building law altogether. In reality, the simplified 2022 procedure changes exactly one thing: instead of waiting for an administrative decision, a notification is enough — and construction can start right away. Every requirement from the local plan, zoning conditions, and all other regulations applies exactly as it would under a classic permit.

The conditions the house must meet

The own-housing-needs declaration isn't a formality

The investor files it under criminal liability for a false statement. That's a real legal risk, not an empty box on a form — take it seriously if your plans for the house's eventual use aren't settled.

What this procedure does NOT change

The simplification applies only to the administrative path — notification instead of a permit. The house still has to comply with the local plan or, absent one, the zoning-conditions decision: designation, parameters, building lines, boundary setbacks. Notification isn't a way around the plan or zoning conditions — if a plot doesn't allow residential building, a 70 m² house won't get it either.

Frequently asked questions

Is 70 m² the house's usable floor area?

No — it's the building coverage, meaning the building's footprint on the ground (the outline of the exterior walls). A two-storey house with 70 m² of coverage can have considerably more usable floor area once both levels are counted.

Can I rent out a house built under this procedure?

The procedure requires a declaration, at the time of notification, that the house is for the investor's own housing needs. Changing how it's used later is a separate legal question — treat this carefully and don't plan this route with renting in mind from the start.

Can the authority object to my notification for a house up to 70 m²?

Under this procedure the authority doesn't run the kind of compliance review, with a right to object, that a classic notification carries before construction starts — which doesn't relieve the investor of responsibility for actual compliance with the plan and regulations, which building-control inspectors can verify later.

First check whether the plot allows a house at all

Before simplifying the paperwork, make sure the plot's designation and parameters actually allow a residential building — that's what the parcel report checks.
