When you're planning to renovate your home or install custom wooden doors, stairs, or kitchen countertops, you might not think about the nesoulad v katastru, rozdíl mezi skutečným stavem budovy a záznamem v katastru nemovitostí. Also known as nepřesnost v katastrálním mapování, it can block permits, delay projects, or even lead to fines. Many homeowners in Brno and across the Czech Republic only discover this issue when they try to get a building permit or sell their flat. And it’s not just about old houses — even recently renovated apartments can have this problem if the previous owner made changes without updating the official records.
This isn’t just paperwork. A nesoulad v katastru, rozdíl mezi skutečným stavem budovy a záznamem v katastru nemovitostí can affect your ability to legally expand a room, move a wall, or even install a new kitchen island. If your kitchen was extended into what was once a hallway — but the map still shows it as a corridor — the authorities might treat it as an unauthorized modification. That’s why checking the katastr nemovitostí, oficiální databáze všech nemovitostí v České republice, která obsahuje plochy, hranice a využití pozemků a budov before starting any renovation is crucial. It’s not just about compliance — it’s about protecting your investment. If you’re buying a flat, you also need to check the SVJ, společenství vlastníků jednotek, které spravuje společné části domu a rozhoduje o úpravách. A poorly managed SVJ might have allowed changes without proper documentation, leaving you with a legal mess after purchase.
And it’s not just about walls and rooms. If you’re planning custom wooden stairs, built-in cabinets, or a new layout for your open-plan kitchen, you need to know exactly what’s allowed. A mismatch between the real structure and the official map can mean your beautiful new interior won’t get approved. You might even be forced to remove it. That’s why we always advise clients to verify the cadastral records before we start designing. It saves time, money, and stress. In our work with homeowners in Brno, we’ve seen too many projects delayed because someone skipped this step. The good news? Most nesoulady v katastru can be fixed — but only if you act early. Below you’ll find real-life examples and practical guides on how to check your property’s status, what documents to ask for, and how to avoid common traps when planning renovations.
