Protection zones: invisible boundaries you won’t see at first glance
When you walk a plot, you see an open space where your future home could stand, but the law sees an invisible network of constraints. Protection zones exist to safeguard nature, infrastructure, or your own safety. Their biggest trap is that they are often not recorded in the land registry as easements.
Yet they are legally binding and can carve out a surprisingly large part of your buildable parcel, an area where you may not even be allowed to put up a fence, let alone a house.
Common “neighbors” that bring statutory limits are forests and watercourses. Even if your house is not inside the forest, the law protects a buffer around it to maintain stand stability and reduce the risk of falling trees. Similarly, along streams and rivers a free manipulation corridor is required so the water authority can maintain the channel with heavy equipment.
If your land is close to roads or railways, expect additional offsets: the more important the corridor, the farther you may need to place your building to preserve space for future repairs or expansion.
Fully invisible are the zones around buried utility networks. Overhead high‑voltage lines are obvious; gas, water mains, and fiber-optic cables are not. Every cable or pipe has a safety corridor where you must not interfere with foundations, and often not with paved surfaces or pools either.
If you build within such a corridor without permission and an incident occurs, repairs can become your liability, and in extreme cases you may be forced to remove the construction at your own expense.
The most important document to verify these constraints is an official planning information statement (ÚPI), which you can request from the relevant building authority. It should list the applicable restrictions for your parcel in writing.
Another practical source is the zoning plan’s coordination drawing, which uses hatching and colors to mark protection zones for roads, forests, and major utility lines. Many municipalities publish these drawings online.
