The definition of self-contained living space is a living space with:
- One's own (lockable) front door and house number;
- A private bathroom (with at least a toilet and shower);
- One's own cooking facility (with a minimum of 1 meter sink with kitchen cabinet and a grounded outlet for the fridge)
As soon as one of the above facilities has to be shared, it is a case of non-self-contained living space.
