Kolaudace: Co to je a proč je důležitá při výstavbě nebo rekonstrukci domu

When you finish building or renovating your home, you don’t just hand over the keys — you need kolaudace, formální proces, který potvrzuje, že stavba odpovídá schválenému projektu a platným předpisům. Also known as stavební kolaudace, it is the official stamp that says your house is safe, legal, and ready to live in. Without it, you can’t legally occupy the building, connect utilities, or even register your address. Many people think it’s just a formality, but skipping it or doing it wrong can cost you tens of thousands — or worse, leave you stuck with an unusable home.

Stavební úřad is the one who controls the whole process. They check everything: from the thickness of walls and insulation levels to the placement of windows, drainage, and even fire safety measures. They compare your finished house to the original building permit — every millimeter matters. If you changed the layout without approval, even just moving a wall, the kolaudace can be delayed or denied. That’s why it’s crucial to keep all documents, signed approvals, and inspection reports from the start. Many homeowners regret waiting until the last week to gather paperwork — by then, it’s too late to fix mistakes.

It’s not just about the structure. Kolaudace also covers technical systems: heating, electrical wiring, water supply, and sewage. If your new bathroom doesn’t drain properly, or your circuit breaker panel doesn’t match the approved design, you’ll get a list of corrections. Some people try to cut corners — using cheaper materials or skipping inspections — but those choices show up during kolaudace. And when they do, you’re forced to redo work you already paid for. It’s better to do it right the first time.

For those renovating older buildings, kolaudace gets even trickier. If your house is protected or located in a historic zone, extra rules apply. You might need to use specific materials for windows or roofing, even if modern alternatives are cheaper. The stavební úřad will check every detail, including whether you preserved original features like cornices or door frames. Ignoring these rules doesn’t just risk the kolaudace — it can lead to fines or even forced restoration at your expense.

So what happens after you pass? You get the kolaudační list — the official document that allows you to use the building. Only then can you legally connect gas, electricity, and water. Only then can you register your residence. Only then can you sell the property without legal risks. Many buyers walk away from homes without it, no matter how beautiful they look. Don’t let your dream home become a legal trap.

Below, you’ll find real-life stories and practical guides from Czech homeowners who’ve been through kolaudace — the mistakes they made, the surprises they faced, and how they finally got it right. Whether you’re building from scratch or renovating an old panelák, this collection gives you the clear, no-nonsense advice you need to avoid costly errors.
