The property is not allowed to live.

You mean that your houses are 1503-2 and 1603, but obviously 1603 and 1503-2 are two separate houses on the drawing. The problem now is that your house can be certified, that is, you have a place to live. There is no doubt about it.

If it is just a misunderstanding of the property, or if it is deliberately occupied 1503, this can be solved by the Housing Authority. But when the owner is away, he usually goes to court in the end. When looking for a property, you should ask the property to be returned to its superior unit, which has this obligation.
