The minimum distance is the distance specified in the regulations, which must be observed when placing buildings and construction objects in relation to the boundaries of the land plot, other buildings, public roads, forests, energy networks or elements of the armament of the site. It is these values that determine where and how you can place the house on the plot so that it complies with the regulations and does not violate the rights of neighbors.

Most often, by this concept is meant the minimum distance of the building from the border of the plot. According to the Regulation on technical conditions, the basic values look like this:

  • 4 meters, if the wall of the building contains windows or doors,
  • 3 meters, if the wall has no windows or doors,
  • 1.5 meters or even at the border of the plot - for narrow plots (less than 16 m wide), but only if additional conditions are met and the office gives consent.

These rules have a practical justification - they protect privacy, provide access to daylight, improve fire safety and make it possible to maintain the building. But that's only part of the puzzle. Minimum distances also apply in other cases, for example:

  • from a public road - usually at least 6 meters from the edge of the roadway (or according to the MPZP),
  • from the forest - most often a minimum of 12 meters,
  • from overhead power lines - depending on voltage,
  • from gas tanks, wells, septic tanks, treatment plants - in accordance with sanitary and technical regulations,
  • from other buildings - for example, in the case of garages, sheds, outbuildings.

Can these rules be waived? In special situations - yes. It is possible to apply to the Office for a derogation from the technical conditions, but this requires justification and the agreement of the competent authority. This is the exception, not the rule.

Important: The MPZP or the Building Conditions Decision (WZ) may introduce other, more restrictive or more flexible distances - these should always be checked before starting the design. For example, a local plan may require a building to be moved 8 meters away from the road or specify specific requirements for the distance from adjacent agricultural parcels.

Why is it worth knowing the minimum distances before buying a plot or choosing a project? Because they can:

  • influence the placement of the building on the plot,
  • limit its width or depth,
  • prevent the implementation of the finished project without adaptation,
  • and in extreme cases - to make the plot too small to legally put up a house.

Imagine: the investor buys a house project with side windows, and the plot is 18 meters wide. Theoretically, everything agrees, but it turns out that the neighbor has already put the building 1.5 m from the border. As a result, it becomes impossible to maintain a full 4-meter gap without changing the design or requesting a derogation. Knowing the recipes in advance would avoid such complications.
